Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a device for treating anal fistula.
Background
Anal fistula refers to an abnormal channel formed by the communication of the rectum or anal canal and the skin around the anus, is also called anal canal rectal fistula, is called anal fistula for short, consists of an inner opening, a fistula and an outer opening, and is one of the common rectal and anal canal diseases.
Anal fistula can not self-heal and needs surgical treatment, and at present, the treatment of middle-high anal fistula mainly adopts a thread-hanging therapy. The traditional thread hanging therapy comprises the following operation steps: (1) the finger-assisted probe extends into the inner opening from the outer opening; (2) bending the front end of the probe and pulling the front end of the probe out of the anus; (3) a silk thread is tied at the front end of the probe, and a rubber band is connected in parallel; (4) the probe is withdrawn, the rubber band is pulled out from the fistula and ligated with silk thread. Therefore, the tissue hooped by the rubber band is subjected to ischemic necrosis, gradually becomes black and falls off, and meanwhile, the subsequent new tissue grows up while the original tissue falls off, so that the fistula is filled, and the anal fistula is cured.
However, the conventional thread-hanging operation has several disadvantages as follows: (1) when an internal fistula of the anal fistula is explored, a slender metal probe is needed, and when the probe is explored in the fistula, the surrounding tissues are easily damaged; (2) the metal needle is not easy to bend, and after the internal fistula is explored, a doctor is required to operate to probe fingers into the anus of the patient, and after the probe is explored, the finger is bent and then the anus is taken out, so that the pain experience of the patient is increased; (3) when a doctor searches for an inner opening, the inner opening is often closed, namely the inner opening is pseudohealed or the pipeline is not smooth, so that the correct inner opening is difficult to find, the thread can not be hung, and the operation is probably firstly cut, so that the pain of a patient is increased; (4) after the thread is hung, the anus of a patient is always in a contraction state due to pain, so that the wound surface outside the anus cannot be completely released, the wound surfaces which are already open are often quickly adhered together, and as a result, the drainage of the external orifice is not smooth, and the fistula is easy to relapse; (5) the rubber band connected with the probe is easy to fall off and break, the former increases the operation difficulty, and the latter requires 2 operations; (6) when a part of anal fistula is hung, the coil is required to be gradually tightened according to the tissue necrosis degree, finally, the tissue in the coil is completely necrotic, and the coil falls off along with the necrosis. However, the step of tightening the coil is complicated, which easily results in the breakage of the rubber band and the failure of the operation.
In addition, when the anal fistula is treated by adopting the seton therapy, a gap is always left between the internal fistula and the seton, and dirt enters the fistula through the gap when a patient defecates, so that healing is affected, even more serious inflammation and abscess are caused, and pain of the patient is increased.
