Description
Technical field
The present invention relates to wire tensioning devices, and in particular to a kind of novel anal fistula wire tensioning device.
Background technique
High complex anal fistula is one of Colon and rectum surgery refractory disease, and in China, the disease incidence of anal fistula accounts for anal intestine disease
The 1.7-3.6% of number of the infected, and external disease incidence is 8.6/10 ten thousand people, wherein high complex anal fistula patient accounts for about whole anuses
The 10% of fistula.Operation is the main means for treating high complex anal fistula at present, but Postoperative recurrent rate is still higher.Therefore, high-order multiple
The treatment of polygamy anal fistula is that the difficult problems of puzzlement anorectum department doctor consider controlling for high complex anal fistula according to clinical practice
It treats difficulty to be, protection anal function and reduction recurrence rate are a pair of contradiction mutually restricted always.Although clinically each at present
Kind Operation of Remaining Musculus Sphincter art formula, as AFP filling art, fibrin percutaneous transcatheter closure and video assist lower Operation of Remaining Musculus Sphincter minimally-invasive treatment art formula
(VAAFT) etc. start to be widely applied in the treatment of anal fistula, but therapeutic effect is still not ideal enough, at present high complex anal fistula
Still using traditional incision hanging wire art as essential therapeutic arsenals, but there are still hanging wire wire rods too to fall behind, and stringing step is too cumbersome,
Patient's pain is heavier when stringing, after stringing, therefore the foundation of good anal fistula seton, stringing scheme, and love wound, painless idea are mesh
One of the research hotspot of preceding anal fistula.
In recent years, although ligating method for treating anal fistula is improved to a certain extent, clinical manipulation demand it is not able to satisfy still, such as
Anus keyhole sample deformity caused by annular cutting, postoperative stringing are insufficient etc. to patient's bring great pain and drainage.Chen Yu
The researching and designings alignment thread-ligating therapy such as root changes the stress side of required cutting tissue by being placed in tough matter leather packing below intramuscular
To the active force of four circumferential heartcuts is become directional cutting from top to bottom.But for clinical practice operation, in muscle
Distal end is encased inside leather packing, easily causes excrement to remain at leather packing after defecation, and cleaning is relatively complicated, and chronic inflammatory stimulation can cause vacation
Property healing；And leather packing is easily embedded in cutting intramuscular after stringing, easily causes sphincterismus, there is constant pain discomfort in patient.Rubber
Rubber band is the most common material of currently most used hanging wire, and the rubber band of many persons separate sources carries out seton treatment, such as
General Purpose Rubber circle or surgical glove rubber ring, but materials variances is huge, can not be standardized due to using, report
Result comparison it is poor.
At present ligating method for treating anal fistula there are the problem of:
1, the selection of hanging wire material not enough standardizes: the material of the hanging wire of clinical application at present is mainly silk thread and rubber band, or
The combination of medical fluid and silk thread has no obvious development in recent years, although the application of medicated thread alleviates hanging wire to trouble to a certain extent
Person's bring pain, but these are inappreciable for the pain of anal fistula patient itself, and the drug that medicated thread uses is more
For toxic medicament, operating specification limits the use for rotten medicine of dispelling.For the rubber band and rubber gloves that are commonly used,
Its intensity, anti-oxidant poor, surface of a wound hanging wire position is in wet environment, and the time is slightly long then to easily lead to rubber band oxidation, in stringing
In the process because aging is broken, in addition, rubber band is without analgesic effect.It takes a broad view contemporary materialogy expert and it is lacked to the research of hanging wire material
Again few, the development of a variety of composite materials is still blank at present.
2, the fine function of anus cannot be protected: although cutting ligating method for treating anal fistula theoretically can it is impaired to avoid anal function,
The risk of incontinence of faces, but some patientss still have different degrees of anal function damage.Christeasen etc. the study found that
Although ligating method for treating anal fistula is high-order through sphincter anal fistula in treatment, more satisfactory in terms of improving cure rate and reducing recurrence rate,
The long term of patient anus sphincter function is assessed and pessimistic, there is 62% patient different degrees of anus self-control function occur
Decline.Therefore external to reduce the damage to anus using drainage hanging wire is empty hanging wire, it only used drawing for tradition cutting hanging wire
Principle is flowed, anal sphincter is not cut off, protects the function of anus to greatest extent, but from the point of view of Long-term, control
Therapeutic effect is unsatisfactory, and recurrence rate is higher.There is document report using the cure rate of empty seton treatment high anal fistula only in 20-
Between 40%, although also obviously not risen using other methods, cure rates such as biological fibrin glues simultaneously.
3, postoperative pain is more significant: postoperative stringing process is too cumbersome, when stringing, after stringing, since rubber band is to group
The dissection knitted, it is that ordinary person can not imagine that the pain generated is heavier.Especially dressing and when stringing, patient often fears
Fear dressing, query is generated to modern medical service level.
4, the operation standard of stringing is difficult to standardize: although ligating method for treating anal fistula has apparent advantage in treatment high anal fistula,
Regrettably, hanging wire scheme do not unify still at present, strong operability, stringing time and stringing in actual operation operation
Elasticity is mostly the summary of experience of each expert clinical, although having a directive significance for clinic, still the basis of shortage evidence-based medicine EBM and
Fine dissection and pathology support, and without long-term clinical observation on the therapeutic effect.
Summary of the invention
