1. main body is made up of thick thin two medical PVC flexible pipes, extra heavy pipe 1 is about 7cm, interior diameter 3.0Mm, 4.5 Mm, 5.5 Mm, thus divide No. 1, No. 2, No. 3.Tubule 2 is about 30Cm, interior diameter 1Mm；

2. tubule 2 is penetrated at the scale of extra heavy pipe 0, it is fixed on thermoplastic elastic glue on the inside of extra heavy pipe tube wall, front end and extra heavy pipe Long side front end is concordant；

3. the other end of tubule 2 sets one small sacculus 3 and is provided with a control valve, the control valve has plug 4, outside Side can mutually be connected with ordinary syringe, and can be taken out when pushing plug 4 open to inhale, and when discharging plug 4, control valve is closed automatically.

4. the rear end of extra heavy pipe 1, which is set, is connected with sustained release cap 5, for the closed mouth of pipe；

5. sustained release cap 5 includes water-absorbing sponge sample material 6, it can slowly discharge by required infusion of medicine wherein and reach treatment Effect.

6th, it is connected with sustained release cap 5 and extra heavy pipe 1 and is provided with an attachment means 10.Mouth is fallen into pipe or falls into prevent sustained release cap 5 In chamber, the one end of attachment means 10 is connected to above sustained release cap 5, and the other end is connected to the junction of extra heavy pipe and tubule, i.e. 0 scale Place.

7th, small micropore is provided with the scale 3-5 of extra heavy pipe 1, is easy to drain.

The utility model is comfortable exquisite, multi-functional, multiduty cyst of jaw negative pressure distraction device.Its feature is soft It is soft, comfortable, clean it is sterile, art area can be implanted directly into operation fixes, early postoperation has that art area is rinsed and negative pressure drainage is made With.Blister cavities flushing, injection can be carried out for a long time；Negative pressure can be formed in blister cavities, interrupts cyst of jaw expansive growth, strengthens cyst wall Fibrous connective tissue centrality bunching after the release of capsule cavity pressure, can stimulate Gegenbaur's cell to generate, so as to shape in this role Into the new bone of prosthetic, mandibular shapes reconstruction, blister cavities is gradually reduced.The device can utilize the medicine such as negative pressure and the curing agent of injection to add Its strong centripetal convergent force, accelerates the accumulation of Gegenbaur's cell and the reparation in Cranial defect area, jawbone profile is improved, and has negative Press distraction osteogenesis effect.Tube chamber, change and skeletonization situation using fiber sem observation blister cavities, according to the feelings of blister cavities mucous membrane can be passed through The concentration of condition adjustment injection of medicine, dosage, interval time；Minimally Invasive Surgery can be carried out, the cyst of jaw operation of complexity is become one Individual needs decompression by fenestration, rinses, makes blind bag, is implanted into the device, shuns the complicated and tackle the simple, substantially reduce operating time, also reduce Surgery cost.

The device operation principle：Interface at tubule sacculus valve can be embedded in ordinary syringe, pushing tow sacculus valve is inside Side is moved, and opens valve, is removed sustained release cap, is formed the close access of the setting-blister cavities, be rinsed and treat；And it can pass through Fiber sem observation blister cavities situation is stretched at cover screw fixture cover end opening.Sustained release cap is filled in, syringe is removed and then closes automatically.Block this to set Put and communicated with the external world, clean sterile in holding chamber, preventing and treating decoction outflows, negative pressure in holding chamber.

With micro- and minimal invasive techniques development and the maturation of distraction osteogenesis, on the basis of a large amount of clinical positions, Applicants have invented cyst of jaw negative pressure distraction device,

This practical new technology integrates flushing, negative pressure drainage and distraction osteogenesis in itself, and simple in construction, light, operation is just Victory, the labor intensity of medical personnel is reduced, mitigate the pain of patient.

Application method of the present utility model is as follows：

In operation, frozen biopsy determines the property of lesion first, and the device is applied to larger benign tumour.Typically exist Vestibule of mouth diease tumour most swelling part cut, decompression by fenestration, cut parts of lesions tissue and send disease inspection, make a definite diagnosis it is benign after cyst wall is opened a window Oral capsule wall forms cyst wall blind bag, according to the age of patient, sex, the position of cyst of jaw and size with mucous membrane of mouth Stitch Selection is adapted to the device of model, and length is adjusted in shearing, the device is entered the most roomy place of blind bag, and 4-0 absorbable sutures will The setting tube wall is fixed with the suture of cyst wall blind bag mouth, and tubule can subcutaneously be drawn from bicker or neck, and needle tubing pushes plug 4, needle tubing open Flushing liquor is transfused, and the waste liquid after cleaning is drawn by control valve, with sustained release cap covering extra heavy pipe rear end, completes operation.By capsule The blind bag of chamber and the setting constitute a closed-loop path, by the positive/negative-pressure in valve, the control of sustained release cap and adjustment closed-loop path, Drug infusion situation.Early stage carries out art area's flushing and negative pressure drainage using the device, can be carried out after the healing of art area blister cavities flushing, Injection, negative pressure distraction osteogenesis, injection curing agent contributes to negative pressure distraction osteogenesis, and can utilize fiber sem observation by tube chamber The change of blister cavities and skeletonization situation, according to the concentration of the situation of blister cavities mucous membrane adjustment injection of medicine, dosage, interval time.

As shown in figure 3, the flushing of the utility model cyst of jaw negative pressure distraction device, entering the medicine course of work and being；Control It is connected behind valve processed with the phase of syringe 12；Syringe 12 pushes up valve opening door, opens sustained release cap 5, syringe injection or sucking-off blister cavities Interior liquid.

In Fig. 3,7 be blister cavities, and 8 be cyst wall, and 9 be jawbone.

As shown in figure 4, being connected syringe needle tube behind valve, needle tubing heads into valve, is sustained cap beyond the Great Wall, and intracavitary is inhaled into negative Pressure, negative pressure is maintained with needle tubing, intracavitary excess tissue liquid may be inhaled in needle tubing.

As shown in figure 5, being connected syringe 12 behind valve, needle tubing heads into valve, the injection of medicine in sustained release cap 5, beyond the Great Wall Cap is sustained, intracavitary is pumped into negative pressure, removes needle tubing, valve piston automatically resets closure, intracavitary holding negative pressure state, negative pressure state The morphologic observation of sacculus can be passed through.

As shown in fig. 6, fibrescope 13 can be stretched into the extra heavy pipe 1 observes situation in blister cavities.

Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic Carry out equivalent substitution.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc., It should be included within the scope of protection of the utility model.
