Description
Technical field
The present invention relates to a kind of medical instruments, especially a kind of fistula hole plugging system.
Background technique
Currently, preferred conservative therapy such as passes through anti-infective, inhibition digestive juice point in the therapeutic process in various internal organs fistulas hole
It secretes, in splanchnocoel or the inside and outside decompression drainage through various natural cavities, enriched nutritive, to promote tissue repair, granulation growth etc. comprehensive
Treatment is closed, expects self-healing, period length, patient are very painful.Some selection second operations repair fistula hole, but operating difficulty is big, risk
Height, success rate is low, the fistula hole after repairing there are still bleeding, the risk of fistula again.
In more typical fistula hole, such as esophagobronchial fistula, gastroesophageal anastomosis fistula, residual gastric fistula, gastrointestinal anastomosis fistula, each
Kind intestinal fistula, vesicovaginal fistula, rectovaginal fistula, stifled fistula is an important measures, makes fistula mouth temporary close, restores alimentary canal, exhales
Road, the urinary tract equicontinuity are inhaled, content is no longer excessive, and reduction content is to the corrosion of surrounding tissue and body fluid loss and thus
Caused by the fatal complications such as infection, big bleeding.Also a relatively clean growing environment is created after stifled fistula, is conducive at fistula hole
The growth of tissue is healed, and effectively shortens treatment time, can comparatively fast restore the normal functions such as alimentary canal, respiratory tract, the urinary tract again.

Inflammation is closed the suture of fistula mouth, folder using interventions approach such as operation or Gastrointestinal Endoscopes, bronchoscope or cystoscopes after being effectively controlled
Or place bracket, but therapeutic effect is inaccurate after being faced with closure, it is more to be disturbed factor, infection around Yi Yinqi fistula mouth, bleeding,
The complication such as local necrosis, the expansion of fistula mouth；After being difficult to block or block failure, one-stage operation fistulization, drainage can only be selected, then
Row second phase repairing fistula mouth and anastomosis, treatment time is long, patient suffering, in art, it is postoperative be also difficult to avoid occurring anastomotic stricture,
The risk of fistula mouth fistula again after the complication such as bleeding, infection and repairing.The appearance of plugging device make many chambers lack, aortopulmonary fistular
Equal patients with congenital heart diseases obtain extraordinary curative effect, avoid the huge damage of openheart surgery, also there is improved envelope at present
Stifled device is applied to the treatment of the hollow organ fistula with infection, etch state, but current plugging device all only carries out fistula hole
Block, fistula hole two sides be isolated, but the liquid for having leaked or slowly having leaked cannot exclude, be easy to cause further infection or
Corrosion, in addition these plugging devices can not block according to scene and require to carry out adaptive big minor adjustment, and universality is poor.Therefore,
It is necessary to design a kind of fistula hole plugging system, there can be certain size expansion character, meet adaptive big minor adjustment, and energy
It is enough to pump out the liquid of leakage, keep sanitation and hygiene at fistula hole to avoid further infecting.
Summary of the invention

In the plugging system of fistula hole disclosed by the invention, plugging device bracket overall structure is made by degradation material, example
Such as poly- l-lactic acid (PLLA), poly- l-lactic acid (PLLA) are a kind of degradable high molecular materials, are food Bureau of Drugs Supervision batch
It will definitely be applied to the degradable substance of implantation human body, after degradable plugging device stenter to implant human body is filled up vacancy, tissue
It can slowly be grown along plugging device bracket, 2-3 or so, human body autologous tissue has growed very solid, and plugging device bracket has been at this time
It is degraded to lactic acid, is digested, water is generated and carbon dioxide excretes, do not leave any trace；Plugging film
It is to be made of biodegradable material, but the degradation cycle of plugging film is longer than the degradation cycle of plugging device bracket, so as to
Enough ensure to realize after the completion of fistula hole is grown and stops membrane degradation.
Fistula hole disclosed by the invention plugging system when in use, covers on the umbrella-shaped structure at plugging device bracket both ends first
Flexible plugging film, the threaded engagement of plug bolt 40 are mounted on the left end of interpolation pipe 2, and film is installed to the hole of circular hole
Side presses on the left end nozzle of interpolation pipe 2, to constitute complete plugging structure；Insertion tube 18 and promotion pipe 19 are distinguished again
In corresponding insertion outer tube 1 and interpolation pipe 2, so that the first spacing block set 21 enters the first limited ring groove 13 by the first notch 14
It is interior, while the second spacing block set 22 is entered in the second limited ring groove 11 by the second notch 15；Pass through grip frame 32 and hand button hole again
31 cooperation pulls interpolation pipe 2 to be retracted in outer tube 1, to pull each U-shaped bar 5 of both ends umbrella-shaped structure by promotion pipe 19
It is drawn close to centre, forms the shuttle shape structure facilitated insertion into fistula hole, then shuttle shape structure is inserted at fistula hole to be blocked；Then
The cooperation for passing through grip frame 32 and hand button hole 31 again pushes interpolation pipe 2 protruding by outer tube 1, to push away by promotion pipe 19
Fold constitutes umbrella-shaped structure to each U-shaped bar 5 at dynamic both ends outward, wants so that pressing in two end side surfaces in fistula hole, is realized to block
It asks；Pipe 19 is pushed so that inner push-rod 20 stretches out to the right with being used cooperatively for disk 33, pressing is limited by grip frame 32 again, is utilized
The left part of inner push-rod 20, which pushes, blocks disk 36, so that being connected inside interpolation pipe 2, to by drawing liquid hole, interpolation pipe 2, push
Pipe 19 and drawing liquid butt tube 39 constitute drawing liquid channel, to will be leaked by the negative-pressure adsorption device installed at drawing liquid butt tube 39
Liquid pumps out, and sanitation and hygiene at fistula hole is kept to avoid further infecting；Simultaneously can also by drawing liquid butt tube 39 by
Drawing liquid channel internally pushes the medical fluids such as growth factor, promotes quick restoration ecosystem at fistula hole；It is finally rotatably inserted into pipe 18, so that
First spacing block set 21 is detached from the first limited ring groove 13 by the first notch 14, while the second spacing block set 22 is taken off by the second notch 15
It from the second limited ring groove 11, extracts insertion tube 18 and pushes pipe 19, complete the accurate positioning installation of plugging device bracket；In insertion tube
After 18 extract with promotion pipe 19, disk 36 is blocked under the resilient support effect of four curved support items 37 to the realization of drawing liquid channel
It blocks again, finally again the plugging film of insert division is carried out tightening closure.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right
Various changes can be made in the form and details for it.
