Embodiment
The present invention relates to a kind of electrosurgical unit with counter.Electrosurgical counter/blocking mechanism of the present invention is designed to carry out two major functions.At first, it carries out a tally function, with the sterilization/use round-robin number of times and/or the remaining sterilization/use round-robin number of times of record electrosurgical unit elapsed sterilization/uses the round-robin number of times and experienced as user's demonstration.Secondly, in case electrosurgical unit has experienced the sterilization/use circulation of pre-determined number, then counter is carried out blocking function, thereby prevents from using described electrosurgical unit in other electrosurgical procedure arbitrarily.
According to one aspect of the present invention, counter comprises indicator, is used to be presented to lose remaining sterilization/use round-robin number of times before to electrosurgical unit.This indicator adopts temperature actuation element and mechanical actuation elements (for example mechanical lance) to increase/reduce counting.The temperature actuation element activated in response to the decontamination cycle that respectively lives through, and mechanical actuation elements activated in response to each use of carrying out circulation.By serviceability temperature actuation element and mechanical actuation elements in combination, eliminated the repeatedly increase of rolling counters forward in single sterilization/use/reduce.
According to one aspect of the present invention, actuator uses with temperature actuation element and mechanical actuation elements and increases/reduce indicator.In this embodiment, in decontamination cycle, the temperature actuation element is along the first direction movement actuator.When actuator when first direction moves, indicator does not increase or reduces.Therefore, a plurality of temperature peaks that may betide in the single disinfecting process can not cause repeatedly change in count.On the contrary, in using circulation, mechanical actuation elements is along the second direction movement actuator, causes the increase of indicator/reduce.A part of mechanical actuation elements (for example mechanical lance) is extended from electrosurgical unit.When the doctor uses this electrosurgical unit---for example insert with the electrosurgery generating is dynamo-electric by a plug portion with apparatus to engage, mechanical actuation elements is pressed into.Being pressed into of mechanical actuation elements makes actuator move and cause the increase of indicator/reduce along second direction.Actuator can not cause another time of indicator to increase/reduce, until the temperature actuation element in follow-up disinfecting process once more along the first direction movement actuator.Realize the change of indicator by serviceability temperature actuation element and mechanical actuation elements in combination, for each sterilization of finishing/use circulation, counter has realized that single ground increases/reduces.
According to another aspect of the present invention, when electrosurgical unit has experienced the sterilization/use circulation time of pre-determined number, counter stops electrosurgical unit to be used.In an embodiment of the invention, counter includes a mechanical lance, in case carried out the sterilization/use circulation of pre-determined number, this machinery lance physically stops apparatus to be used.
Referring now to accompanying drawing, Fig. 1 shows according to first embodiment of the present invention to Fig. 4 B, and Fig. 5 shows according to second embodiment of the present invention to Fig. 9, and Figure 10 shows according to the 3rd embodiment of the present invention.
As used in this, following term should have following meaning:
Term " sterilization/use circulation " should refer to the sterilization and the use of electrosurgical unit, and no matter these movable orders that take place.Though the description of the invention mode is " sterilization/use circulation ", be to be understood that teaching of the present invention is sufficiently wide, and be intended to comprise " use " that vice versa in " sterilization " situation afterwards; Crucial part is: between the continuous use of each electrosurgical unit (no matter think disinfecting process betide given use before or afterwards), counter of the present invention only increases/reduces single counting.
Term " reduces/increase " should to refer to be combined in reducing of employed counting in the counter of the present invention or increases, and finishes with indication sterilization/use round-robin.Though embodiments of the present invention disclosed herein are described as: for each sterilization/use circulation, counter " reduces ", but be to be understood that, teaching of the present invention is enough widely, and intention comprises that counter circulates and the situation of " increase " for each sterilization/use.
In addition, will use hereinafter agreement to describe the orientation of each member of counter of the present invention at this.
For Electrosurgical instrument, " far-end " is often referred to active electrode substantially, by this active electrode the patient carried out electrosurgery.Because the preferred implementation of counter of the present invention disclosed herein is placed in the plug-in unit---wherein this plug-in unit is used for electrosurgical electrode is connected to the electrosurgery generator, so, " far-end " when refer to counter and immediate that end of Electrosurgical instrument (promptly with Figure 1A in power lead 4 immediate ends), and " near-end " is when finger counter and Electrosurgical instrument that end (end that promptly has termination 8a-c in Figure 1A) farthest.Sometimes, constitute counter of the present invention each member towards also similarly term expression.
Referring now to being shown in the embodiment of Fig. 1 in the 4B, described accompanying drawing shows according to first embodiment of the present invention, and wherein electrosurgical unit 1 includes counter 10.Counter 10 is arranged in the power connector of electrosurgical unit 1, and described power connector is configured to insert in the Electrosurgical power supply---electrosurgery generator (not shown) for example.Electrosurgical unit 1 comprises the housing 2 that is used to protect electrosurgical unit 1 internals, is used for electrosurgical current is transported to the power lead 4 of Electrosurgical instrument (not shown), the termination 8a-c that is used for the window 6 of the one or more indications on the sight indicator 22 and is used for electrosurgical unit 1 is connected to the electrosurgical power supplies (not shown) from the generator (not shown).
Enter on Figure 1A now, counter is a part of electrosurgical unit 1.Counter is followed the tracks of electrosurgical unit 1 elapsed sterilization/use round-robin number of times, and in case stops electrosurgical unit 1 to be used after having finished the sterilization of pre-determined number/use circulation.This will follow the tracks of as where working together the member of counter performed sterilization/use round-robin number of times, and after stop the further use of apparatus to be discussed.As what those skilled in the art understood, can adopt the mechanism of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, can usage counter mechanism and do not use blocking mechanism.In another embodiment, can use blocking mechanism and usage counter mechanism not.
In the embodiment shown, counter includes indicator 22 and mechanical lance 40.Indicator 22 comprises a plurality of marks, and described mark illustrates to be finished or also remaining sterilization/use round-robin number of times, thereby the user can determine when electrosurgical unit should be lost.In each sterilization/use circulated, indicator 22 increased/reduces and indicates the change of sterilization/use cycle index of having finished.Thus, electrosurgical unit 1 is followed the tracks of remaining sterilization/use round-robin number of times that electrosurgical unit 1 can carry out, and follows the tracks of sterilization/use round-robin number of times individually and need not the user.
For illustrative purposes, describe remaining accompanying drawing with reference to following counter, this counter is presented at electrosurgical unit and should be dropped remaining before access times and adopts an indicator that all reduces after each sterilization/use circulation.As those skilled in the art are known, can use the method for polytype and structure and mechanism to show when electrosurgical unit ought be dropped and can not depart from category of the present invention and spirit.For example, in one embodiment, counter can be indicated the sterilization/use round-robin number of times that has carried out and use an indicator that all increases after each sterilization/use is circulated.In another embodiment, counter can be indicated relativeness between the sterilization/use round-robin number of times finished and the sterilization/use round-robin total degree that can carry out (for example in the 1st time, 4 times in 4 times the 2nd inferior).In another embodiment, counter may not indicated sterilization/use round-robin number of times of having carried out, but at internal monitoring sterilization/use round-robin number of times.In the embodiment of example and description, adopt the locked position of coupler of mechanical lance to indicate electrosurgical unit to have been lost herein to the user.In another embodiment, can adopt a kind of mechanism that is different from indicator to indicate user's electrosurgical unit when when being lost.
As those skilled in the art understand, can adopt the indicator of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, indicator reduces after once sterilizing circulation, but can again not reduce subsequently, until after carried out using and circulated and decontamination cycle.In another embodiment, indicator is indicated the residue sterilization/use cycle index that can carry out at electrosurgical unit before being dropped.In another embodiment, sterilization/use round-robin total degree that the indicator indication was carried out.
In the embodiment shown, mechanical lance 40 is on the position of partly stretching out.When the sterilization of pre-determined number/when use circulation did not also reach, mechanical lance 40 arrived at the part extended position.Machinery lance 40 is to be used to survey an example using the round-robin device.Being used for surveying other this device of use round-robin is known for a person skilled in the art.For example, be used for follow-up use key removable striker and have chip software, electric light source, bar chart, can be used as and survey to use the round-robin device.
As those skilled in the art understood, the Electrosurgical counter/blocking mechanism of polytype and structure can use with the electrosurgical unit of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, counter is used in the body of a surgery electroprobe or Other Instruments, rather than is used in the power connector.In another embodiment, counter is used for a part of modular electrosurgical apparatus, and this part carries out disinfection at the other parts after separating with described electrosurgical unit.In another embodiment, indicator illustrates sterilization/use round-robin number of times of having finished, and this number of times is the function of the sterilization/use cycle index of being recommended.
Figure 1B is the vertical view of electrosurgical unit 1, and mechanical lance 40 is in and is pressed into the position shown in it.For clarity, shown termination 8a-c is not inserted in the Electrosurgical power supply.As those skilled in the art were understandable, in a typical use was provided with, because termination 8a-c is inserted in socket or other the electrosurgical power supplies (not shown), mechanical lance 40 was pushed in the housing 2 of electrosurgical unit 1.Because mechanical lance 40 is pushed in the housing 2 of electrosurgical unit 1, indicator 22 slides along the direction of power lead 4, makes that one or more mark of indicator 22 is changed.The change of mark is indicated to the user: with indicated the comparing of Figure 1A, remaining access times have reduced once.
Fig. 1 C shows electrosurgical unit 1, and wherein mechanical lance 40 is in complete extended position.In the embodiment shown, the length of mechanical lance 40 length of being stretched out from the housing 2 of electrosurgical unit 1 and termination 8a-c about equally.After the sterilization of having finished predetermined quantity/use cycle index, mechanical lance 40 moves on to the locked position of coupler that stretches out fully.When mechanical lance 40 moved on to the locked position of coupler that stretches out fully, it can not be pushed in the housing 2 again.In this structure, mechanical lance 40 prevents that physically termination 8a-c links to each other with the power supply (not shown), thereby has stoped the further use of electrosurgical unit 1.When mechanical lance 40 was in the locked position of coupler that stretches out fully, window 6 makes that the user can sight indicator 22 and determine: electrosurgical unit 1 did not have remaining access times.
As those skilled in the art are known, can adopt the counter of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, the mechanical lance of blocking mechanism can stretch out from housing by two or more different overhangs.In another embodiment, lance can stretch out from housing by single overhang, its role is to reduce indicator and blocking function is provided.In another embodiment, first mechanism is reduced counter as a mechanical actuation elements, and second mechanism is used as a blocking mechanism.In other embodiment, the distance that striker stretches out from housing can be greater than or less than the length of termination.
The structure of shown indicator 22 makes the user to monitor remaining access times before should abandoning electrosurgical unit 1.By remaining access times are shown,, make it before will undergoing surgery, to replace to electrosurgical unit 1 for the user provides enough chances.As those skilled in the art understand, can adopt the counter of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, can use such counter: its obstruction or prevent that electric current from flowing to power lead from the termination.At one alternatively in the embodiment, in case finished predetermined sterilization/uses cycle index, then counter can so that modular electrosurgical apparatus member before performing the operation, can not correctly assemble.
Fig. 2 is the inside three-dimensional view of electrosurgical unit 1, and it shows the counter 10 according to one embodiment of the present invention.In the embodiment shown, counter 10 includes indicator assemblies 20, mechanical lance 40, bias spring 48, actuator 50, temperature actuation element 70, spring 80 and actuator engagement member 90.
Make actuator 50 correctly to operate by a mechanical actuation elements (being mechanical lance 40) and a temperature actuation element 70.When using electrosurgical unit 1, mechanical lance 40 activated at every turn.The operation of temperature actuation element 70 and each decontamination cycle of carrying out interrelate.Machinery lance 40 causes with combining of temperature actuation element 70: for each sterilization of carrying out/use circulation, actuator 50 single actuation.In one embodiment, temperature actuation element 70 makes actuator 50 move along first and second directions with mechanical lance 40 ordinatedly.This makes that actuator 50 can mobile indicator 22 and realize finishing the variation of one or more marks to show that sterilization/use circulates.
In the embodiment shown, mechanical lance 40 comprises pin or bar and comprises near-end 42 and far-end 44.Near-end 42 is between termination 8a and termination 8b, and at extended position be pressed between the position selectively and move.The far-end 44 of machinery lance 40 is adjacent to actuator 50 and indicator 22 (view 3A), and is configured to engage and mobile indicator 22 with actuator 50.Being pressed into mechanical lance 40 causes actuator 50 to move.In the embodiment shown, the near-end 42 of mechanical lance 40 is in the position of stretching out.When mechanical lance 40 by when far-end is setovered, the far-end 44 of mechanical lance 40 engages with actuator 50.This causes actuator 50 to move towards distal direction.
In the embodiment shown, temperature actuation element 70 is by marmem---for example for still being not limited to Nitinol
When temperature actuation element 70 is in enough following times of temperature, it is returned to initial shape and is rigidity, is not easy to bending.Thereby when electrosurgical unit 1 experience once sterilizing circulation time, because the hardening of temperature actuation element 70, temperature actuation element 70 is from the configuration of the more linearly type shown in the topographical variations one-tenth of a bending.The hardening of temperature actuation element 70 pushes away actuator 50 direction of past termination 8a-c.This causes actuator 50 with respect to indicator 22 displacements.Temperature actuation element 70 is an example that is used for surveying the device of the temperature that is higher than room temperature.Can adopt the device of polytype and structure to survey the temperature that is higher than room temperature and can not depart from category of the present invention and spirit.For example, in one embodiment, can adopt such temperature actuation element: its magnetic can vary with temperature.In another embodiment, can adopt so a kind of temperature actuation element: the part that it comprises the liquid part of a response temperature fluctuation or is filled with liquid.
Bias spring 48 is holding mechanical lance 40.Bias spring 48 with 40 biasings of mechanical lance to proximal direction, thereby do not stretch out from housing 2 when making near-end 42 when mechanical lance 40 with wall, socket or other surperficial contact.After the sterilization of having finished pre-determined number/use circulation, spring 80 impels mechanical lance 40 to arrive at locked position of coupler.Activate engagement member 90 and impel actuator 50 laterally to move, to guarantee the each actuating for actuator 50, indicator 22 single ground reduce.In addition, activate engagement member 90 and mechanical lance 40 interactions, thereby maintain the mobile route of the expectation of mechanical lance 40, control stretching out of mechanical lance 40 simultaneously, until the sterilization of having finished pre-determined number/use circulation.
Fig. 3 A is the inside vertical view of electrosurgical unit 1, its show according to the parts of the counter 10 of one embodiment of the present invention and connect setting.In the embodiment shown, the counter 10 that illustrates is before the use first of electrosurgical unit 1.In the illustrated embodiment, indicator assemblies 20 is shown.Indicator assemblies 20 comprises indicator 22, guide member 29, pawl spring 30 and clamp structure 34.Indicator 22 is indicated sterilization/use round-robin number of times remaining before should abandoning electrosurgical unit 1 to the user.
In the embodiment shown, indicator 22 comprises mark 24, tooth 26, guide channel 27 (view 2) and latch portion 28.Mark 24 is positioned on the upper surface of indicator 22.In the embodiment shown, mark 24 includes a plurality of lines and relevant reference number.A plurality of lines and relevant reference number indication remaining access times before should abandoning electrosurgical unit 1.The position of indicator 22 is so selected: when corresponding residue access times did not also carry out, suitably the position of mark (lines and relevant reference number) was located at and can observes part (view 1A-1C) by window 6.Along with indicator 22 leaves its near-end, also changed by the observed one or more marks of window 6 (Fig. 1).In the embodiment shown, indicator 22 reduces towards the mobile counter that makes of distal direction.
Get back to Fig. 3 A, latch portion 28 is positioned near the mechanical lance 40, be in the nearly angle of indicator 22.Latch portion 28 is configured to: when indicator 22 was shifted to its farthest position, mechanical lance 40 can activate engagement member 90 along laterally moving apart.Pawl spring 30 is fastened on the indicator 22.Pawl spring 30 is cooperated with clamp structure 34, thereby makes the accidental movement of indicator 22 to minimize.Pawl spring 30 comprises elastic arm 31 and pawl spring soldered tooth 32.Elastic arm 31 is out of shape and makes pawl spring soldered tooth 32 to move with respect to the tooth of clamp structure 34.Pawl spring soldered tooth 32 is configured to be arranged on respectively organizing between the tooth or engaging one or more teeth of clamp structure 34 or between the adjacent teeth of clamp structure 34 of clamp structure 34, thereby makes that the accidental movement of indicator 22 is minimized.When actuator 50 made that indicator 22 moves, the flexibility of elastic arm 31 was enough to allow pawl spring soldered tooth 32 to move apart clamp structure 34 along the direction of indicator 22.This makes pawl spring soldered tooth 32 can remove, cross the tooth far away first group of tooth from the position between first group of tooth and enter between second group of tooth.In the embodiment shown, pawl spring soldered tooth 32 is between first group of tooth.This be because: electrosurgical unit 1 does not also live through and uses for the first time circulation, and mechanical lance 40 does not also use in the circulation for the first time and is not pressed into.
As those skilled in the art understand, can use the indicator of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, indicator comprises seven-segment display, and described indicator is illustrated in and should abandons electrosurgical unit remaining access times before.In another embodiment, indicator includes a ring-type element.In another embodiment, indicator is a gear drive.In another embodiment, indicator comprises digital indicator.
Continue with reference to figure 3A, actuator 50 engages indicator 22 ordinatedly and causes indicator 22 to move backward.In the embodiment shown, actuator 50 includes projection 52, cam path 56, indicator soldered tooth 60 and groove 64, shows groove 64 in Fig. 2 in more detail.As shown in Figure 3A, projection 52 interacts with actuating engagement member 90 and impels actuator 50 pivoting actions.Cam path 56 interacts with pin 58 and causes actuator 50 to move backward, makes also that simultaneously actuator 50 can the motion pivotally in response to being pressed into of mechanical lance 40.The pivoting action of actuator 50 makes actuator 50 that indicator 22 is moved single decrease, and irrelevant with the difference in the displacement of the displacement of single sterilization/use circulation back pointer 22 and mechanical lance 40.
During the initial reverse of actuator 50, indicator soldered tooth 60 engages with the tooth 26 of indicator 22.During power lead 4 motion, along with the nearly portion of actuator 50 begins horizontal pivot, indicator soldered tooth 60 breaks away from the tooth 26 of indicators 22 at actuator 50.In case indicator soldered tooth 60 breaks away from the tooth 26 of indicator 22, indicator 22 further moves backward and stops.
In the embodiment shown, the projection 52 of first end, the 82 contact activated devices 50 of spring 80 and remain on the position of expectation by the supporting construction 88 that is formed in the housing 2.When mechanical lance 40 was not between actuator 50 and indicator 22, first end 82 of spring 80 to indicator 22, activated projection 52 biasings near the engagement member 90 thereby projection 52 is placed.Actuator 50 comprises groove 64 (also seeing view 2).The near-end 72 of groove 64 ccontaining temperature actuation elements 70.By making temperature actuation element 70 to locate simply and effectively with respect to actuator 50, groove 64 helps the assembling of locking/counter mechanism 10.The structure of groove 64 and temperature actuation element 70 makes actuator 50 motion as required in response to decontamination cycle, too accurately makes or assembles and need not counter 10 parts.
Describe very much the operation of actuator 50 in detail with reference to Fig. 3 B-4B.Fig. 3 B is the inside vertical view of electrosurgical unit 1, and it illustrates the motion that actuator 50 is pressed in response to the part of mechanical lance 40.In the embodiment shown, the near-end 52 of mechanical lance 40 has moved towards distal direction, but it moves the inside that whole length that degree do not make mechanical lance 40 all is positioned at housing 2.When being setovered towards the distally along with mechanical lance 40, the far-end 44 of mechanical lance 40 engages with actuator 50.This causes actuator 50 to move towards distal direction.Along with actuator 50 moves towards distal direction, indicator soldered tooth 60 engages with a tooth 26 of indicator 22.When actuator 50 engaged with indicator soldered tooth 60, along with actuator 50 distad moves, indicator 22 moved along distal direction.When indicator 22 along distal direction move past one predetermined apart from the time, realized the change of mark.The user that changes into of mark is illustrated in remaining access times after the sterilization finished/use circulation.In the embodiment shown, along with moving of at first 0.06 inch of actuator 50, the change of mark and pawl spring soldered tooth 32 move.
Be pressed further into along with mechanical lance 40 in the housing of electrosurgical unit 1 (moving to the position of Fig. 3 C from the position of Fig. 3 B), actuator 50 pivots and leaves indicator 22, prevents that indicator 22 from further moving backward.In Fig. 3 B, the tooth 26 that the nearly portion of actuator 50 begins to pivot and leaves indicator 22.Yet actuator soldered tooth 60 does not also separate with tooth 26.The structure of projection 52 and actuator engagement member 90 is convenient to actuator 50 and is left from indicator 22 pivots.Before mechanical lance 40 was pressed into, projection 52 was arranged in the groove 92 of actuator engagement member 90, as shown in Figure 3A.When 40 beginnings of mechanical lance along shown in Fig. 3 B backward during movement actuator 50, the horizontal translational surface 94 of the horizontal translational surface 54 contact activated device engagement members 90 of projection 52.Laterally translational surface 54 causes projection 52 to begin pivot with the horizontal interaction between the translational surface 94 leaving indicator 22.
In case projection 52 begins to pivot, far-end 44 beginnings of mechanical lance 40 contact with the inclined-plane 62 of indicator soldered tooth 60.When the far-end 44 of mechanical lance 40 by when distal direction promotes, 62 the length slip of mechanical lance 40 along the inclined-plane.This causes projection 52 to pivot further and laterally moves apart indicator 22.Laterally moving of projection 52 also causes laterally moving of indicator soldered tooth 60.Cam path 56 makes actuator 50 to move pivotally with the structure of pin 58, and this pivoting action is owing to following factors becomes easy: (a) the laterally interaction between the translational surface 54 and 94; And (b) interaction between the inclined-plane 62 of the far-end 44 of mechanical lance 40 and indicator soldered tooth 60.
When mechanical lance 40 repeatedly partly was pressed into, the structure of the tooth 26 of indicator 22 and indicator soldered tooth 60 prevented that with respect to the set-up mode of tooth 26 more than 22 ground of indicator from reducing.When mechanical lance 40 is pressed into fully and causes indicator 22 to reduce, in that being pressed into, mechanical lance 40 follow-up can cause needing activation temperature actuation element 70 before indicator 22 reduces further.Thus, the user can repeatedly insert or extract termination 8a-c, perhaps is pressed into mechanical lance 40 and can cause reducing of indicator 22.
Fig. 3 C is the inside vertical view of electrosurgical unit 1, and wherein mechanical lance 40 fully is pressed in the housing 2.The pivot of actuator 50 causes indicator soldered tooth 60 to break away from the tooth 26 of indicator 22.The further reverse of actuator 50 and/or mechanical lance 40 can not make indicator 22 move further, because the tooth of indicator soldered tooth 60 and indicator 22 is what to separate.The far-end 44 of machinery lance 40 keeps separating between mobile between indicator soldered tooth 60 and the tooth 26 makes actuator 50 and indicator 22.
The pivoting action of actuator 50 makes: no matter the displacement of the displacement of mechanical lance 40 and indicator 22 how, actuator 50 can make indicator 22 reduce single position.In one embodiment, in each actuating of mechanical lance 40, mechanical lance 40 is pressed into roughly 0.25 inch.In one embodiment, in each actuating of mechanical lance 40, indicator 22 only moves 0.060 inch.As those skilled in the art understand, can change the amount of movement of mechanical lance with respect to the amount of movement of indicator and can not depart from category of the present invention and spirit.In one embodiment, indicator is removable 0.01 inch to 0.75 inch.In another embodiment, indicator is removable 0.02 inch to 0.125 inch.In another embodiment, the distance that lance moved is greater than distance that indicator moved.In another embodiment, the distance that moves of lance and indicator depends on the size of the housing of electrosurgery blocking mechanism and ccontaining this electrosurgery blocking mechanism at least in part.In addition, the actuator of polytype and structure be can adopt and category of the present invention and spirit can not departed from.
When actuator 50 along far when mobile, masterpiece is used on the temperature actuation element 70, increases the curvature of temperature actuation element 70.When temperature actuation element 70 did not cause the rigidity of temperature actuation element 70 to increase because of being heated, the curvature of temperature actuation element 70 increased.Thus, temperature actuation element 70 provides minimum resistance, makes the far-end 74 of temperature actuation element 70 more near the near-end 72 (Fig. 2) of temperature actuation element 70.Because the position of temperature actuation element 70 far-ends 74 keeps by seat 76, so the near-end 72 of temperature actuation element 70 will move towards the direction of far-end 74.
In case actuator 50 breaks away from indicator 22, extracting and inserting subsequently of termination will can not cause moving of indicator 22 in the socket.Reason be because: indicator soldered tooth 60 no longer contacts with indicator 22.Machinery lance 40 can not cause actuator 50 to move towards indicator 22 directions along moving of termination 8a-c direction, can not cause indicator 22 to be engaged by indicator soldered tooth 60 yet.Thus, the user can repeatedly extract and insert the termination and can not reduce indicator 22.When mechanical lance 40 was pressed into, flange 46 caused the compression of bias spring 48 near bias spring contact member 96.The compression of bias spring 48 causes a bias force to act on the flange 46, and the direction of this power deviates from bias spring contact member 96, as long as electrosurgical unit 1 is pulled up from the electrosurgical power supplies (not shown), this power will force mechanical lance 40 to be returned to its extended position.
Along with sterilization/use round-robin repeatedly carries out, indicator 22 will move step by step along the direction of power lead 4.Along with the direction of indicator 22 along power lead 4 moves further, one or more marks 24 show, for the user indicates remaining sterilization/use round-robin number of times.As those skilled in the art understand, can adopt the blocking mechanism of polytype and structure and can not depart from category of the present invention and spirit.
As indicated above, in the embodiment shown in Fig. 1-4B, indicator 22 comprises pawl spring 30, and this pawl spring 30 makes indicator 22 as one man reduce.Pawl spring 30 comprises flexible arm 31, contacting between the pawl spring soldered tooth 32 that this arm 31 keeps pawl springs 30 and the tooth of clamp structure 34.In Fig. 3 B, pawl spring soldered tooth 32 is between one group of tooth, and this group tooth is immediately following after 32 residing those group teeth of pawl spring soldered tooth in Fig. 3 A.Reason be because: electrosurgical unit 1 has experienced for the first time and to have used circulation, and this circulation causes indicator 22 to move.
As mentioned above, pawl spring 30 comprises elastic arm 31, and this elastic arm keeps contacting between the tooth of pawl spring soldered tooth 32 and clamp structure 34.Along with indicator 22 reduces, the power that acts on the indicator 22 by actuator 50 causes moving of pawl spring soldered tooth 32.Engaging between pawl spring soldered tooth 32 and the clamp structure 34 prevents moving of indicator 22, until the power that on indicator 22, act on by lance 40 and actuator 50 above a threshold value.This makes when never the being pressed into lance 40 wittingly indicator 22 non-possibility minimums that desirably move.Lance 40 had a mind to that to be pressed into---for example when being inserted into termination 8a-c in the electrosurgical power supplies (not shown) produce---sufficiently big and exceeded mobile pawl spring soldered tooth 32 and make it to break away from the position that is between 34 first groups of teeth of clamp structure, cross a tooth in this group tooth and enter the threshold value of the required power in the position between second group of tooth everywhere.In addition, the structure of the tooth of clamp structure 34 prevents pawl spring soldered tooth 32 towards proximad moving, and allow pawl spring soldered tooth 32 towards far to move.
By the distance that makes that pawl spring soldered tooth 32 is advanced and limited between mechanical lance 40 is pressed into for twice, pawl spring 30, pawl spring soldered tooth 32 and clamp structure 34 also make indicator keep correctly reducing.As those skilled in the art understand, can adopt the mechanism of polytype and structure to make the non-desired motion of indicator minimize and can not depart from category of the present invention and spirit.
Turn to Fig. 3 D, its show after electrosurgical unit 1 uses but before the decontamination cycle subsequently when the partly operation of actuator 50 when housing 2 stretches out of mechanical lance 40.Fig. 3 D shows: when the position of moving electrosurgical unit 1 internal part when indicating electrosurgical unit to be used a time to the user fully of indicator 22.
As shown in the figure, spring 80 adjacent actuator 50 and mechanical lance 40 are provided with.Spring 80 is configured to keep the parts of counter 10 correctly to work.First end 82 of spring 80 contacts with the projection 52 of actuator 50.When mechanical lance 40 no longer was between the tooth 26 of indicator soldered tooth 60 and indicator 22, spring 80 was with the direction biasing towards indicator 22 of the projection 52 of actuator 50.In one embodiment, the biasing to actuator 50 can impel indicator soldered tooth 60 to engage with the tooth 26 of indicator 22.In another embodiment, need activation temperature actuation element 70 to make indicator soldered tooth 60 engage with the tooth 26 of indicator 22.
When indicator 22 was not in the displacement of distal direction maximum, indicator 22 contacted at least one part of mechanical lance 40 at adjacent distal end 44 places, and provided cross-brace along this part one side, for second end 84 of spring 80 provides a reacting force.Second end 84 of spring 80 and the reacting force of indicator 22 are controlled laterally moving of mechanical lance 40.In the embodiment shown, the far-end 44 of mechanical lance 40 slightly is thicker than the other parts of mechanical lance 40.The section thickness of far-end 44 is so selected: far-end 44 is wideer than tooth 26 and the gap that activates between the engagement member 90, makes the inside surface that activates engagement member 90 (promptly facing to that surface of the lance 40) prevent that the far-end 44 of mechanical lance 40 from crossing and activates engagement member 90.
Turn to Fig. 4 A, it shows electrosurgical unit 1 after activation temperature actuation element 70 but the inside vertical view after a series of sterilizations/use circulation.When activateding, temperature actuation element 70 is returned to actuator 50 on the such position: wherein indicator soldered tooth 60 engages with the tooth 26 of indicator 22 once more.To the actuating of temperature actuation element 70 be indicator 22 reduce get ready.In the embodiment shown, temperature actuation element 70 engages with actuator 50, makes activateding back temperature actuation element 70 maintenance nonlinear type configurations.By keeping the nonlinear type configuration, when needs were pressed into mechanical lance 40, temperature actuation element 70 stoped the bulged-in possibility of mechanical lance 40 to reduce.
In Fig. 4 A, temperature actuation element 70 comprises marmem---such as but not limited to Nitinil
When temperature actuation element 70 is subjected to enough temperature, its be returned to initial shape and be rigidity and be not easy to bending.Thereby when electrosurgical unit 1 experience once sterilizing circulation, then temperature actuation element 70 is transformed into a more linear configuration from a bent position (Fig. 3 C), shown in Fig. 4 A.The more linear configuration of temperature actuation element 70 is caused by firmization of temperature actuation element 70.Firmization of temperature actuation element 70 promotes actuator 50 along the direction of termination 8a-c, contacts until the far-end of pin 58 with cam path 56.This causes actuator 50 with respect to indicator 22 displacements.
With reference to Fig. 2 and 4A, temperature actuation element 70 is arranged in a seat 76, and described seat 76 is formed in the housing 2 of electrosurgical unit 1.The far-end 74 of temperature actuation element 70 engages with seat 76 and the far-end 74 that prevents temperature actuation element 70 moves along the direction of power lead 4.The near-end 72 of temperature actuation element 70 engages at groove 64 places with actuator 50, and this groove (can see best in Fig. 2) is formed in the sidepiece of actuator 50.
When temperature actuation element 70 is heated to a predetermined temperature (for example in disinfecting process), the rigidity of temperature actuation element 70 increases, intensity increases and flexibility reduces.Firmization of temperature actuation element 70 reduced the curvature of temperature actuation element 70.When temperature actuation element 70 was subjected to enough heating, its configuration from general curved (Fig. 3 C) was transformed into the more configuration of linear pattern and rigidity, caused near-end 72 to promote actuator 50 along the direction of termination 8a-c, shown in Fig. 4 A.
In Fig. 4 A, temperature actuation element 70 provides one to promote and movement actuator 50.By utilizing this to promote, temperature actuation element 70 has reduced the manufacturing cost and the complexity of counter 10, has improved the fiduciary level of system simultaneously.Reason is: firmization of temperature actuation element 70 moved actuator 50 effectively and do not needed accurately to make size, thickness and the length of temperature actuation element 70.This has reduced the design and the manufacturing cost of temperature actuation element 70.In addition, temperature actuation element 70 does not need to be coupled to integratedly other parts of counter 10 to remain on needed tolerance in the pull-up activated apparatus.On the contrary, at assembly process, temperature actuation element 70 can be easily positioned in seat 76 and the groove 64 (view 2), has greatly reduced assembling complexity, expense and the degree of difficulty of counter 10.As those skilled in the art understand, can adopt the actuation element of polytype and structure and can not depart from category of the present invention and spirit.In one embodiment, the temperature actuation element is configured to provide a pulling force, thereby causes the correct actuating of indicator.
Continue with reference to figure 4A, because the structure of the indicator soldered tooth 60 of the tooth 26 of indicator 22 and actuator 50, actuator can't cause moving of indicator 22 towards moving of termination 8a-c direction.In addition, the repetition heating and cooling of temperature actuation element 70 can not cause repeatedly reducing of counter, because moving of indicator 22 only takes place in response to being pressed into of mechanical lance 40.Thus, actuator 50 can not cause the change of one or more marks 24, has experienced decontamination cycle and along a direction movement actuator 50 and the use that mechanical lance 40 has experienced to be indicated by being pressed into of lance circulation and along opposite direction movement actuator 50 until temperature actuation element 70.
Fig. 4 B is the inside vertical view of electrosurgical unit 1, and it shows the position of the electrosurgical unit 1 different internal parts after decontamination cycle, and this electrosurgical unit has exceeded the sterilization number of times of being recommended.As shown in the figure, spring 80 and indicator 22 are fastened on mechanical lance 40 on the position of stretching out ordinatedly.In the embodiment shown, indicator 22 has been finished its last reducing, and no longer contacts with the far-end 44 of mechanical lance 40.When indicator 22 no longer contacted with the far-end 44 of mechanical lance 40, it no longer provided cross-brace and no longer provides a reacting force to stop second end 84 of spring 80 for second end 84 of spring 80.Thus, second end 84 of spring 80 contacts the far-end 44 of mechanical lance 40 and it is biased into the latch portion 28 of indicator 22.This makes far-end 44 cross actuating engagement member 90, and allows mechanical lance 40 to move to a locked position of coupler that stretches out fully, shown in Fig. 4 B.
In the time of near latch portion 28 is positioned at actuating engagement member 90, second end 84 of spring 80 is along the far-end 44 of lateral offset machinery lance 40.This provides the extra distance that activates between engagement member 90 and the indicator 22, thereby the distance between feasible actuating engagement member 90 and the indicator 22 is greater than the width of mechanical lance 40 far-ends 44.Thus, activating engagement member 90 no longer contacts with the far-end 44 of mechanical lance 40 in the mode that the reacting force of bias spring 48 on flange 46 is provided.When not existing, cause mechanical lance 40 mobile towards proximad by bias spring 48 the power on the flange 46 of acting on because of when activating engagement member 90 reacting force that provides be provided.In an embodiment of the invention, bias spring contact member and actuating engagement member and lower part of frame form.In optional embodiment, bias spring contact member and actuating engagement member can not be fixed on one or more parts of housing 2 movably.
In the embodiment shown, when flange 46 contacted with the inside surface of housing 2, proximad moving of mechanical lance 40 stopped.When flange 46 contacted with the inside surface of housing 2, mechanical lance 40 fully stretched out from housing 2.Second end 84 of spring 80 contacts with indicator 22 and mechanical lance 40 is fastened in the position of stretching out.Indicator 22 be in its maximum far on the shift position, and contact with backstop 25.Backstop 25 is formed by the bottom of housing 2.Backstop 25 prevents that indicator 22 is back further to displacement.
The far-end 44 of indicator 22, second end 84 and mechanical lance 40 prevents that mechanical lance 40 is pressed into.Shown in the position on, mechanical lance 40 is shifted from housing the biglyyest.By preventing that mechanical lance 40 is pressed into, prevented engaging of termination 8a-c and power supply (not shown).Thus, in case finished after the sterilization/use circulation of pre-determined number, counter 10 stops the user to use electrosurgical unit 1.In the embodiment shown, pawl spring Contact Tooth 32 is between last group tooth of clamp structure 34.This be because: electrosurgical unit 1 has experienced the sterilization of pre-determined number/uses and has circulated, and indicator 22 is positioned on its shift position farthest.
As those skilled in the art understand, can adopt the blocking mechanism of polytype and structure and can not depart from category of the present invention with spirit.For example, in one embodiment, blocking mechanism adopts the lateral offset mechanism that comprises the sheet spring.In another embodiment, blocking mechanism adopts the lateral offset mechanism that does not comprise the sheet spring.In another embodiment, blocking mechanism does not adopt lateral offset mechanism.In another embodiment, blocking mechanism does not comprise latch portion.
Fig. 5 is the interior views of electrosurgical unit 100, and it illustrates the counter 110 according to another embodiment of the present invention.In order to help to explain the structure and the function of electrosurgical unit 100 sum counters/blocking mechanism 110, in Fig. 5-9, never illustrate from power lead 104 up to the electric wire of termination 108a-c or other the equipment that is electrically connected.
In the embodiment shown, counter 110 comprises indicator 122, actuator 150, temperature actuation element 170 and mechanical lance 140.Temperature actuation element 170 and mechanical lance 140 make actuator 150 move along first and second directions ordinatedly.This makes that actuator 150 can mobile indicator 122 and realize finishing the change of one or more marks thereby sterilization/use circulation is shown.
In the embodiment shown, temperature actuation element 170 is marmems---for example, still be not limited to Nitinol
When temperature actuation element 170 is in enough following times of temperature, it is returned to initial shape and is rigidity, is not easy to bending.Thereby when electrosurgical unit 100 experience once sterilizing circulation times, because 170 hardening of temperature actuation element, temperature actuation element 170 is varied to the more linearly configuration of type (as shown in Figure 8) from the bending position shown in.The hardening of temperature actuation element 170 pushes away actuator 150 direction of past termination 108a-c.This causes actuator 150 with respect to indicator 122 displacements.
After decontamination cycle, when the user is intended to use electrosurgical unit 100---for example by termination 108a-c being inserted into electrosurgery outlet (not shown), the near-end of mechanical lance 140 will be touched and be pushed into the inside of housing 102.Actuator 150 is around the mechanical lance 140 of a part.The part that machinery lance 140 is positioned at actuator 150 inside engages with the inside surface of actuator 150.Thus, when mechanical lance 140 when the direction of power lead 104 moves, actuator 150 moves along the direction of power lead 104.In other words, when mechanical lance 140 was forced in the housing 102, actuator 150 was pushed to the direction of power lead 104.When actuator 150 was pushed to the direction of power lead 104, the surface that actuator 150 engages with the complementary surface of indicator 122 caused indicator 122 to move along the direction of power lead 104.Indicator 122 mobile makes the position change of mark, thereby indication sterilization/use circulates and finishes.This also causes electrosurgical unit 100 remaining access times to reduce.
When external force no longer acted on the near-end of mechanical lance 140, bias spring can be so that mechanical lance 140 stretches out from housing 2.This causes the near-end of mechanical lance 140 to stretch out from housing 2.Yet actuator 150 does not move towards termination 108a-c direction, activated in response to decontamination cycle until temperature actuation element 170.Thus, further being pressed into of mechanical lance 140 can not cause actuator 150 and indicator 122 to move, until having carried out decontamination cycle subsequently.Machinery lance 140 is one and surveys an example using the round-robin device.For those skilled in the art, other sniffer is known.For example being used for the removable striker of key of follow-up use and the software, electric light source, the bar chart that have a chip can be used as to survey and uses the round-robin device.
Fig. 6 A and 6B are the partial sectional view of electrosurgical unit 100, and it illustrates the parts of Electrosurgical counter/blocking mechanism 110 and a kind of connecting mode (view 6B) of temperature actuation element 170 and mechanical actuation elements (being mechanical lance 140) and actuator 170.In the embodiment shown in Fig. 6 A, temperature actuation element 170 be arranged in the seat 176---this is formed at the housing 102 of electrosurgical unit 100.The far-end 174 of temperature actuation element 170 engages with seat 176 and prevents that temperature actuation element 170 from moving along the direction of power lead 104.The near-end 172 of temperature actuation element 170 engages (not shown) with actuator 150.
When the temperature of temperature actuation element 170 raises (for example in disinfecting process), temperature actuation element 170 rigidity and intensity increase, and the flexibility of temperature actuation element 170 reduces.Firmization of temperature actuation element 170 reduced the curvature of temperature actuation element 170.When temperature actuation element 170 was sufficiently heated, its configuration from general curved changed over the more configuration of linear pattern and rigidity, and wherein near-end 172 promotes actuator 150 towards the direction of termination 108a-c.
Push movingly by utilization, temperature actuation element 170 has reduced the manufacturing expense and the complexity of blocking mechanism 110, has improved the reliability of system simultaneously.This be because: firmization of temperature actuation element 170 moved actuator 150 effectively and do not needed accurately to make size, thickness and the length of temperature actuation element.This has reduced the design and the manufacturing cost of temperature actuation element 170.In addition, temperature actuation element 170 other parts of not needing to be coupled to counter 110 integratedly keep needed tolerance in the pull-up activated apparatus.On the contrary, temperature actuation element 170 can be provided with in present 176, has greatly reduced assembling complexity, expense and the degree of difficulty of counter 110.
In the embodiment shown, the near-end 142 of lance 140 is positioned at outside the housing 102 of electrosurgical unit 100.The far-end 144 of lance 140 is suitable for being positioned at the inside (view 6B) of actuator 150.The far-end 144 of machinery lance 140 engages with actuator 150, thereby causes actuator 150 to move when mechanical lance 140 is pressed into.The engagement ridge 145 (view 6B) of machinery lance 140 engages with engagement member 190, and this engagement member 190 is coupled to the housing 102 of electrosurgery 100.Engagement member 190 prevents that engagement ridge 145 from moving and crosses a given position on the direction of termination 108a-c.Thus, the near-end 142 of mechanical lance 140 can not be crossed a given position along moving of termination 108a-c direction.
For operation easy and that more be shown clearly in the counter parts, several parts that Fig. 6 B illustrates actuator 150 and counter separate.In the embodiment shown, actuator 150 comprises body 152, conduit 154 and tooth 156.Body 152 keeps the rigidity and the structure of actuator 150, and provides enough intensity to come mobile indicator 122 (when being engaged by temperature actuation element 170 (referring to view 6A)) and mechanical lance 140.Conduit 154 is limited and is suitable for the far-end 144 of ccontaining mechanical lance 140 by body 152.This maintained actuator 150 towards, make laterally moving of mechanical lance 140 far-ends 144 minimize simultaneously.Tooth 156 is formed in the body 152 of actuator 150.The tooth 156 of actuator 150 engages with the tooth 126 of indicator 122.When actuator 150 was mobile backwards, the structure of tooth 156 and tooth 126 made indicator 122 backwards to moving.When actuator 150 when forward direction moves, the structure of tooth 156 and tooth 126 can not make that indicator moves.
Get back to Fig. 6 A, indicator assemblies 120 includes indicator 122 and guide member 129.Indicator 122 is suitable for moving with respect to other parts of electrosurgical unit 100, is used to refer to sterilization/use round-robin number of times of having finished and changes.Guide member 129 engages indicator 122 ordinatedly, so that laterally moving of indicator 122 minimizes and guarantee that indicator 122 steadily and effectively slides in response to moving of actuator 150.In the embodiment shown, guide member 129 comprises the sliding part that the height that is positioned at conduit rises, and this channel shaped is formed in the bottom of indicator 122.
As those skilled in the art understand, can adopt the guide member of polytype and structure and can not depart from category of the present invention and spirit.In one embodiment, guide member includes a plurality of non-desirably tooth (not shown)s of motion of indicator that prevent.In another embodiment, anti-skidding material (not shown) is arranged between the bottom surface of the top of guide member and indicator, move with the non-expectation that prevents indicator.In another embodiment, guide member includes a surface, produces enough rubbing contact between this surface and the indicator, thus the non-expectation that prevents indicator move, promptly any is not with respect to moving of actuator and moving of causing by mechanical lance.
In one embodiment, towards the needed power of termination direction movement actuator much smaller than along power lead direction movement actuator and the needed power of indicator.In another embodiment, the power of movement actuator of being used for that is provided by the temperature actuation element is used for the power of movement actuator and indicator much smaller than mechanical actuation elements provided.In the embodiment shown, mechanical lance 140 applies a power on actuator 150.Then, actuator 150 engages actuator 122 and transmit movement actuator 122 needed power.Actuator 150 is described in more detail and indicator 122 moves in response to sterilization/use round-robin with reference to Fig. 7 and 8.
Fig. 7 illustrates the interior views of electrosurgical unit 100, and it shows indicator 122 and moves moving of being carried out in response to mechanical lance 140---when the position of indicator 122 among comparison diagram 5 and Fig. 7.In Fig. 7, mechanical lance 140 is pressed into, thereby makes the whole length of mechanical lance 140 all be positioned at the inside of housing 102.As indicated above, the far-end 144 of mechanical lance 140 (view 6B) engages actuator 150.This causes actuator 150 to move along the direction of power lead 104.When actuator 150 when the direction of power lead 104 moves, the tooth 156 of actuator 150 engages the tooth 126 of indicators 122.This causes indicator 122 to move along the direction of power lead 104.When indicator 122 when the direction of power lead 104 moves, mark has changed, and finishes remaining access times after once sterilizing/use circulation for the user is presented at.In addition, when actuator 150 when the direction of power lead 104 moves, temperature actuation element 170 is returned to such structure: under the effect that is being applied to power on the actuator 150 or influence by mechanical lance 140, the temperature actuation element has curvature largely.When temperature actuation element 170 does not bear the temperature of the rigidity increase that causes temperature actuation element 170, the described curvature largely that temperature actuation element 170 can have.Thus, temperature actuation element 170 provides minimum resistance, make near-end 172 can more close joint far-ends 174 in present 176.
When mechanical lance 140 was pressed into, flange 146 shifted near engagement member 190, caused the further compression of bias spring 148.Being compressed in of bias spring 148 applied a power on the flange 146, in case make that near-end 142 will stretch out from the housing 102 of electrosurgical unit 100 when interaction force no longer was applied on the near-end 142 of mechanical lance 140.In case when actuator 150 is in present position, termination 108a-c extracted and insert subsequently will can not causes the extra of actuator 150 to be moved in the socket.This be because: lance 140 far-ends are engaged in the actuator 150 slidably.Machinery lance 140 can not cause actuator 150 moving along termination 108a-c direction along moving of termination 108a-c.Thus, the user can repeatedly insert and extract termination 108a-c and can not make that indicator 122 reduces.
Fig. 8 illustrates electrosurgical unit 110 and is in the decontamination cycle.In the embodiment shown, temperature actuation element 170 changes to more linear configuration from bent configuration shown in Figure 7.More linear configuration is the structure that rigidity increases, and the reason that this rigidity increases is the temperature variation during decontamination cycle.The rigidity that is increased provides a such pulling strengrth: it has exceeded the pulling strengrth when temperature actuation element 170 does not bear high temperature.When being in more linear configuration, the near-end 172 of temperature actuation element 170 promotes actuator 150 along termination 108a-c direction.
Because the structure of the tooth 126 of indicator 122 and the tooth of actuator 150, actuator 150 does not cause moving of indicator 122 along moving of termination 108a-c direction.In addition, owing to indicator 122 only moves in response to being pressed into of mechanical lance 140, so temperature actuation element 170 repeat heat up and cool off the repeatedly increase that can not cause counter and/or reduce.Thus, actuator 150 can not cause the change of mark, has experienced once sterilizing circulation and has experienced one along a direction movement actuator 150 and mechanical lance 140 and used circulation and along opposite direction movement actuator 150 until temperature actuation element 170.
Along with having carried out repeatedly sterilization/use circulation, indicator 122 will progressively move along 104 direction.When indicator 122 further when 104 direction moves, demonstrate different marks, indicate the change of the remaining access times of electrosurgical unit 100 for the user.As those skilled in the art understand, can adopt the counter 110 of polytype and structure and can not depart from category of the present invention and spirit.For example in one embodiment, temperature actuation element movement actuator and indicator, and mechanical lance makes actuator move with respect to indicator.In another embodiment, temperature actuation element and lance both or one of directly do not link to each other but movement actuator indirectly with actuator.In another embodiment, temperature actuation element and lance do not use actuator just to make mark change.In another embodiment, actuator spurs indicator and makes indicator move.
Fig. 9 shows Electrosurgical counter/blocking mechanism 110, and wherein indicator 122 moves to the most close power lead 104 places, and mechanical lance 140 is in locked position of coupler.In case indicator 122 moves to the most close power lead 104 places, latch portion 128 is positioned near the actuator 150.Sheet spring 180 applies a transverse force along indicator 122 directions on actuator 150.Indicator 122 is positioned at the position of the most close power lead 104, makes that latch portion 128 can ccontaining actuator 150.This causes actuator 150 transverse shifts in the latch portion 128 of indicator 122.
The far-end 144 of machinery lance 140 is positioned at the conduit 154 (view 6B) of actuator 150.Actuator 150 transverse shifts cause the direction transverse shift of the far-end 144 of mechanical lance 140 along indicator 122 in latch portion 128.The transverse shift of far-end 144 causes engagement ridge 145 to be disengaged member 190 (view 6B).Thus, thus engagement member 190 can not offset again by bias spring 148 and be applied to the power that is applied on the flange 146 on the mechanical lance 140 along termination 108a-c direction.In the embodiment shown, bias spring 148 applies the power along termination 108a-c direction at flange 146, make length that the near-end 142 of mechanical lance 140 stretches out from housing and termination 108a-c length about equally.In another embodiment, the length of mechanical lance length of stretching out from housing and termination and unequal or close.
After electrosurgical unit 100 had been finished its last sterilization/use circulation, indicator 122 contacted with backstop 125.Backstop 125 is formed by the bottom of housing 102.Indicator 122 is stoped by backstop 125 along further moving of power lead 104 directions.When actuator 150 is pushed into when engaging with latch portion 128, actuator 150 is stoped by latch portion 128 along moving of power lead 104 directions.The machinery lance along power lead 104 directions move by contacting between the front surface of the far-end 144 of mechanical lance 140 and actuator 150 stop.
When actuator 150 is pushed into when engaging with latch portion 128, actuator 150 laterally is shifted.The transverse shift of actuator 150 makes the conduit 154 and the far-end 144 of mechanical lance 140 not line up.Thus, the far-end 144 of mechanical lance 140 contacts rather than slips in the conduit 154 with the front surface of actuator 150.In addition, sheet spring 180 engages with actuator 150, prevents that lateral actuator from moving and guarantees that the far-end 144 of mechanical lance 140 does not slip back in the conduit 154 of actuator 150.
Contacting between the far-end 144 of the front surface of actuator 150 and mechanical lance 140 stops mechanical lance 140 moving towards power lead 104 directions.In other words, indicator 122, actuator 150 and mechanical lance 140 and connect to be provided with and prevent that mechanical lance 140 is pushed in the housing 102.Thus, in case finished predetermined sterilization/use cycle index, when user's intention was inserted into termination 108a-c in the Electrosurgical power supply (not shown), mechanical lance 140 stoped electrosurgical unit 100 to be used.
As those skilled in the art understand, can adopt the blocking mechanism of polytype and structure and can not depart from category of the present invention and spirit.For example, in one embodiment, blocking mechanism disconnects the electrical connection of an inside, stops electric current flowing in electrosurgical unit.In another embodiment, blocking mechanism stops the coupling of modular electrosurgical apparatus part, thereby prevents that effectively electrosurgical unit is used.
With reference now to Figure 10,, shows optional structure according to the Electrosurgical counter/blocking mechanism of one aspect of the invention.In the embodiment shown, temperature actuation element 270 and mechanical actuation elements (for example mechanical lance 240) engage with actuator 250.Actuator 250 causes indicator 222 to move.In the embodiment shown, indicator 222 is rotary-type indicators, and it has a plurality of teeth 226 and a plurality of mark 224.Tooth 226 engages and rotation indicator 222 with actuator 250.Indicator 222 mobile causes demonstrating different mark 224, and described a plurality of marks 224 are positioned on the indicator 222.
Very similar with the Electrosurgical counter/blocking mechanism among Fig. 1-9, in using circulation, the lance 240 of counter 210 is moved in the housing.This causes indicator 222 to rotate, and reason is because the tooth that is formed in actuator 250 (not shown)s engages ordinatedly with one or more teeth 226 of indicator 222.Temperature actuation element 270 activated in response to the heat that is used for decontamination cycle.Temperature actuation element 270 is firmization in response to decontamination cycle, causes actuator 250 to move along the termination direction of electrosurgical unit.This so locatees actuator 250: be pressed into the rotation that mechanical lance 240 will cause indicator 222 in response to using circulation.The structure of temperature actuation element 270 and mechanical lance 240 has been guaranteed: for each sterilization/use circulation, single change is realized in the position of mark 224 on the indicator 222.
In the embodiment shown, indicator 222 comprises latch portion 228.Latch portion 228 is configured to the nearly portion of ccontaining lance 240 and/or the part of actuator 250, thereby prevents that lance 240 is forced in the housing of electrosurgical unit after having finished the sterilization of pre-determined number/use circulation.In the embodiment shown, in case finished the sterilization/use circulation of pre-determined number, latch portion 228 is positioned near the actuator 250.Lateral offset member 280 applies a lateral offset power on mechanical lance 240, the nearly portion that causes mechanical lance 240 moves towards the direction of indicator 222.The transverse movement of machinery lance 240 causes mechanical lance 240 to separate from engagement member 290, allows bias spring 248 mechanically moving lances 240, thereby makes the far-end of mechanical lance 240 stretch out the length length about equally with contiguous termination.In case mechanical lance 240 stretches out, laterally mobile mechanical actuator 250 is moved into latch portion 228 of mechanical lance 240 and lateral offset member 280 engages, thereby stops the nearly portion of mechanical lance 240 to be inserted once more in the actuator 250.Thus, prevent that mechanical lance 240 is withdrawn in the housing of electrosurgical unit.
As those skilled in the art understand, can adopt the indicator of polytype and structure and can not depart from category of the present invention with spirit.For example, in one embodiment, indicator includes a plurality of marks, and described a plurality of marks can be independent of moving of indicator and move.According to another embodiment of the invention, indicator includes a seven-segment display, and described indicator is based on simulation or digital signal and increase.
The present invention can other specific forms implements and can not depart from its spirit or principal character.Described true mode will be understood that it is exemplary rather than restrictive.Therefore, category of the present invention is determined by appended claim rather than is determined by description above.All drop on the implication and the interior variation of scope that are equal to claim and all are included within its category.
