Description
Technical field
The invention belongs to the armarium technical field, relate to a kind of device that automatically Baryan is delivered into dental root canal system, realize the X line contrast examination of root canal system by this device.
Background technology
Root canal system is positioned at the tooth body, comprises main root pipe, collateral pulp canal, secondary root pipe, the narrow district of root pipe, root pipe communicating branch, tip of a root bifurcated and difference etc., and its anatomic form is different because of tooth, and is very complicated.Root canal is the basic fundamental of modern dental pulp disease and periapical disease treatment, it is thoroughly to remove infected material in the whole root canal system by various machineries and method chemistry, the whole root canal system of tight then sealing, thus reach the purpose of effecting a radical cure dental pulp and periapical disease.Therefore, the understanding to the root canal system anatomic form is to carry out the prerequisite of root canal and basis.
At present mainly be after opening marrow, to observe the anatomic form that the root canal orifice form is inferred the root pipe clinically before root canal by ordinary x-ray film before the art.This method exists many defectives and influence factor: 1. ordinary x-ray film is to distinguish the different tissues structure by the natural X line resistance range degree of various tissues, because root canal system is thinner and tiny with respect to tooth body and surrounding tissue thereof, and normal and tooth body and surrounding tissue thereof are overlapping, so image is unclear on ordinary x-ray film; Even 2. main root pipe image as seen, also be difficult to differentiate the image of root pipe regions of disorder such as collateral pulp canal, secondary root pipe, the narrow district of root pipe, root pipe communicating branch; 3. the structure of root tip root pipe more can't be differentiated; 4. owing to the root canal system form significant change often takes place from the root canal orifice to the apical foramen of tooth, so the form of root canal orifice can not reflect the form of hypomere in the root pipe.Based on above defective, infer that in conjunction with observation root canal orifice form after opening marrow the anatomic form of root canal system is a difficulty and insecure by ordinary x-ray film.
Baryan is injected in the low tissue of X line resistance range degree strengthening itself and the contrast of surrounding tissue, and clinical thereby the clear method that shows its structure is applied to already at medical domain, its effect is also confirmed by putting into practice.Contrast agent is introduced dental root canal system, promptly carry out the X line contrast examination of root canal system, research and application are also arranged both at home and abroad, significantly improved doctor's root canal preceding diagnosis and understanding complicated root canal anatomy form.Organize the different characteristics of radiography but the inspection of root pipe interimage has with other: 1. root canal system is generally all more tiny, and the region of disorder is many; Root canal wall is harder, and expansivity is little; 2. root canal system one end is embedded in the alveolar bone, is a cecum isolated with air, and when contrast agent entered the root pipe, gas was difficult for eliminating and often forms bubble in the root pipe.There is the method for contrast agent being introduced the root pipe of report to mainly contain two kinds of methods at present: 1. syringe needle to be inserted in the root pipe and inject; 2. after contrast agent being injected pulp chamber, adopt small size root canal file to insert in the root pipe contrast agent is imported the root pipe.These two kinds of methods all can't be guaranteed contrast agent is distributed to whole root canal system fully, and usually produce a large amount of bubbles in the root pipe, have a strong impact on the correct diagnosis to the root canal anatomy structure.Therefore, how contrast agent is conveyed into whole root canal system smoothly and reduces the key that bubble produces just becomes the radiography success or not.At this problem, do not see that special technology and solution are arranged both at home and abroad at present.
Summary of the invention
For solving the technical problem that exists in the present root pipe visualization, the invention provides a kind of X-ray contrast medium transport device in root-canal, this device can be automatical and efficient Baryan is conveyed into smoothly whole root canal system and reduces bubble produces.
The technical solution used in the present invention for this device mainly comprise vacuum pump, belt switch to logical valve, location of contrast agent delivery head, be used to store the syringe and the pressure vacuum gauge of contrast agent, vacuum pump is connected with pressure vacuum gauge, location of contrast agent delivery head by connection tube, logical valve one end is linked to each other with the location of contrast agent delivery head by connection tube, and the other end links to each other with the syringe that is used to store contrast agent by connection tube.
Its intermediate pump is a rotary-vane vaccum pump, and its end vacuum pressure is answered≤20mba (2 * 10
3Should guarantee that effective vacuum range reaches≤30mba (3 * 10 when Pa), device moves
3Pa).And rotary-vane vaccum pump by connection tube with prevent to be connected with the location of contrast agent delivery head by connection tube again after filtering core device that liquid sucks vacuum pump is connected.
The location of contrast agent delivery head is made of inside and outside two not connected sleeve pipes, interior pipe box is in outer tube, and its interior external diameter is all significantly less than outer tube, and interior pipe is than outer pipe range, outer tube links to each other with filtering core device by connection tube, and interior pipe links to each other with the end to logical valve of belt switch by connection tube.
Connection tube is made by transparent rigid plastics.Pressure vacuum gauge show pressure limit 0～-0.1MPa.
Because this device has adopted the principle of negative pressure of vacuum, by the vacuum pump aerofluxus, make the vacuum negative pressure condition that reaches certain in the root canal system, Baryan can automatically be conveyed in the whole pipe through special location of contrast agent delivery head under the driving of negative pressure of vacuum, realization is to the radiography of whole root canal system, reduce and avoid the generation of bubble simultaneously, the radiography effect is fine.And the whole operation process of this device is easy fast, and device various piece cleaning sterilization is also convenient, is fit to very much clinical practice.
