Description
Aug. 23, 1955 K. s. MaGLEAN CURETTE Filed Nov. 21, 1952 INVENTOR. Kenia/ Je/am/Vwaf 7mm/frs United States Patent O CURETTE Kenneth Sheldon MacLean, New York, N. Y.
Application November 21, 1952, Serial No. 321,815
8 Claims. (Cl. 12S-2) This invention relates to surgical instruments for removing material from the walls of a cavity, and more particularly to curettes.
It is an object of this invention to provide a curette having a tubular member as its central part leading from a spoon to a discharge opening.
It is another object of this invention to provide a curette adapted to facilitate the removal of the collected material through a hollow shank into a hollow handle and a discharge opening at the opposite end of the curette from the spoon.
It is a still further object of this invention to provide a curette with a removable blade seated in a spooncontaining head so as to be completely enclosed except for the Working surface.
It is still another object of this invention to provide a curette from which the material may be removed by suction.
These and other objects of this invention will become more apparent upon consideration of the following description, taken together with the accompanying drawings in which:
Fig. 1 is a top plan view of a curette according to this invention;
Fig. 2 is a longitudinal sectional view of the curette, taken on line 2 2 of Fig. 1;
Fig. 3 is a radial section of the curette of Fig. 1, taken on line 3 3 of Fig. 2;
Fig. 4 is an enlarged view of the end ot the curette of Fig. 1 in section, with a suction nozzle in elevation; and
Fig. 5 is an enlarged view of the modified end of the curette of this invention.
In general, this invention provides a curette which has a central passage through a shank and handle from a collecting spoon adjacent a blade to a discharge opening at the opposite end. rIlle central passage facilitates the removal of the collected material either by the suction of the material or the flushing of the material from the curette, as well as providing a storage place for the material in the curette.
Referring to Fig. l, a curette of this invention is shown having a main portion 11. The main portion 11 has at one end a collecting spoon 12 and a shank 13 on which the spoon 12 is mounted. A handle 14 is detachably mounted on the end of the main portion 11 opposite the spoon 12.
As shown in Fig. 2 a central passage 15 extends to the main portion 11 from an aperture 16 to a discharge opening 17. The central passage 15 extends through the spoon 12 and the shank 13. The central passage 15 opens adjacent a blade 18 at the end of the curette. This blade which is held in position by any suitable means is mounted so that the blade 18 projects beyond the aperture 16 a slight distance so as to provide a projecting working edge 19. The end of the shank 13 adjacent spoon 12 is curved so that the axis of the spoon 12 is at an angle to the axis of the shank 13.
rlice A valve sleeve is inserted in the discharge opening 17 and has a head 21 which is positioned outside of the end of the main portion 11 at the end of the handle 14. The valve sleeve 20 has a tubular passage 22 which continues the central passage 15. The valve sleeve 20 is closed by a plug 23 which seats into the tubular passage 22. Adjacent the discharge end of the curette 10 the handle 14 and the main portion 11 are provided with small holes which, when aligned, provide an air vent 24 from the central passage 15. As shown in Figs. 2 and 3, this air vent 24 is in the upper side of the handle 14 and main portion 11 extending vertically downward. The valve sleeve 20 is split by a central slot 25, as shown in Fig. 3. The valve sleeve 20 is rotatable with relation to the handle 14 and main portion 11 so that the slot 25 may be moved in and out of alignment with the air vent 24. When the valve sleeve 20 is rotated to be out of alignment with the air vent 24, the air vent 24 is closed ofi from the central passage 15. The head 21 of the valve sleeve 20 provides a convenient means for rotating the valve sleeve 20.
In Fig. 4, a suction nozzle 26 is shown positioned in the tubular passage 22. The nozzle 26 may be connected by suitable means to any suction apparatus. In Fig. 5, a tube 27 according to this invention is shown with a modiied discharge end for receiving a modied nozzle 28. The modied nozzle 28 has a male thread 29 which screws into a suitable female thread 30 in the interior of the tube 27. Similarly to nozzle 26, nozzle 28 may be suitably connected to suction means for removing material from the tube 27.
The nozzle 26 of Fig. 4 may be replaced by a suitable syringe, not shown. The syringe filled with a iiushing luid is inserted in the tubular passage 22 and operated to discharge into the central passage 15, forcing before it material out through the aperture 16 of the spoon 12.
The device of this invention is used to remove material from internal cavities of the body. Among the purposes of the removal of the material from the internal cavities of the body is the obtainment of samples of the cavity Wall for examination and testing. The device of this invention facilitates this operation. In the use of the device of this invention the tool, properly sterilized, is used with the handle 14 positioned as shown in the figures. The valve sleeve 20 is positioned with the central slot 25 in alignment with the air vent 24. The curette 1t) is inserted in the internal cavity and operated so that the edge 19 of the blade 18 scrapes the desired material from the cavity Wall. The removed material is received through the aperture 16 into the spoon 12. As more material is collected, the material in the spoon 12 is forced into the central passage 15 of the shank 13. The material can be collected in the central passage 15 in considerable quantities so that it is not necessary to remove the curette from the cavity until the desired amount of material has been collected.
The handle 14 remains outside of the cavity. The air vent 24 in the handle 14 provides an escape for the air in the central passage 15 as the material is collected therein. The curette lil may be used to collect the sample material in the passage and retain it there until the end of the operation, at which time the material is removed from the passage 15. When the curette is thus used, the plug 23 remains xed in the tubular passage 22 of the sleeve 20 to close the discharge opening 17.
The curette 10 may also be operated to remove the material constantly during the operation. This is obtained according to this invention by attaching a vacuum line to the discharge opening 17 after a removal of the plug 23. The valve sleeve 22 is rotated to the position shown in Fig. 4 so that it closes the air vent 24. The nozzle 26 inserted in the discharge opening 17 and attached to a vacuum means applies suction to the central passage during the use of the curette 10 in the operation. Thus, as the material is collected the spoon 12 it is drawn thrQugll the Central passage 1.5 and eut. threuehhe nozzle 2.63 In the. med'ied f QrIr'l @fthe emette of tlisinvention ShQwn in Eig- 53111@ modified nozzle Zfijs Serene@ int@ the Central' passage 1 '51 The. @rette sthea elerateA the same as for the 'embodiment described above.`
When the emette, 1.0 is .used t0 celled and' retain. the. material in the central passage 15, the material i's removed after the operation. This removal is achieved by removing, the plus 2-3 from the discharge. Qpenns, 1 7 and in- Setina a Syringe im@ the discharge Opening. l?. similar to. the lSlion of the nozzle 26, as shown in Fig. 4. Upon Operation ofthe. Syringe the material' iS than flushed from the curette.
The device of thijs` invention is of' particular value in the removal` of the entire lining of an internal body cavity. In carrying on such an operation the device of this iriventionl provides a` widel mouth and' a wide blade of sub: stantially the same width as they mouth which remove and collect material and funnel it into a narrower passage. The effect of` the relationship of the parts is such asto employ the cooperation between the cavity lining: and the Wide mouth aperture 16 to produce a pressure on the collected material which will facilitate the movement of the collected material 'm the passage 15'. In one type of use devices of this invention are used to removethe entire lining of a body cavity by inserting the instrument into the cavity and by continuous strokes scraping the lining. At the same time, the instrument is gradually Yrotated so that. the aperture 1 6 continually faces a new portion of the cavity wall. Finally, the entire lining will be removed upon rotating the instrument through a circle ofy 360'. It will be understood that in operations of the type described several instruments may be needed for a single operation.
Itis a feature of this invention andi the operation of the d eviceof thisV invention that the aperture 16,' has a relatively larger area than theY radial area ofthe hollow passage. The spoon 12/ has a funnelshape, tapering from, a wide portion at the aperture 16 to a relatively narrow portion at the junction with the shank 13.
Among the advantages of this invention is the provision of an instrument which facilitates the operation of' removing body cavity lining by employing the pressure of the bodyA cavity lining on the large aperture to force material into the central passage. In the removal of theV cavity lining it isoften important that no shred of the collected material be lost from collection. This complete collection is often of vital importance where certain pathological tests and determinations are to be carried out. The f device of this invention assist-s the recovery of-y such material.
Various modiiications may be made in the device of this invention without departing from the spirit thereof. Other applications of the principle of the present invention will read-ily be apparent to those skilled in the artof surgical instruments. All such variations, modilications and extensions of the principles of the present invention are to beunderstood asbeing embraced Within the appended 4 Y claims. The inventor desires to be limited by the scope of those claims alone.
