Device for treating anal fistula

Abstract

The invention relates to a device for treating anal fistula. The device comprises: a silk thread; magnetic beads, wherein the magnetic beads are of a spherical structure, the number of the magnetic beads is multiple, and the multiple magnetic beads are connected to the silk thread; a plugging structure, wherein the plugging structure is fixedly connected to the middle of the silk thread and used for plugging an inner opening of the anal fistula. The device for treating anal fistula, provided by the invention, can replace a probe for use, and cannot damage tissues around the fistula; through the magnetism of the magnetic beads, the magnetic beads at the anal fistula inner opening can be conveniently sucked out from the anus, fingers do not need to stretch into the anus for blind finding, and operation is easy and convenient; after the device penetrates through the fistula, the magnetic beads at the two ends of the silk thread are attracted to form a closed-loop structure, continuous pressing force is generated on tissue in a closed loop through magnetic attraction force between the magnetic beads, the tissue in the closed loop is subjected to avascular necrosis, the silk thread is not prone to breakage, and the use reliability is improved. The plugging structure can reliably plug the inner opening of the anal fistula, dirt is prevented from entering the fistula, and healing is facilitated.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more specifically, relates to a device for treating anal fistula. Background technique [0002] Anal fistula refers to the abnormal channel formed by the connection between the rectum or anal canal and the skin around the anus. It is also called anorectal fistula, or anal fistula for short. . [0003] Anal fistula cannot heal itself and requires surgical treatment. At present, the treatment of middle and high anal fistula mainly adopts hanging thread therapy. The operation steps of the traditional thread-hanging therapy are: (1) fingers assist the probe from the outer opening to the inner opening; (2) bend the front end of the probe and pull it to the outside of the anus; (3) tie a thread to the front end of the probe, and Connect a rubber band; (4) withdraw the probe, pull the rubber band out from the fistula, and tie it with silk thread. In this way, the tissue held by th...

Problems solved by technology

[0004] However, there are several disadvantages in the traditional thread-hanging operation: (1) a slender metal probe is needed to detect the internal fistula opening of anal fistula, which will easily cause damage to surrounding tissues when the probe is probed in the fistula; (2) Moreover, the metal needle is not easy to bend. After detecting the internal fistula opening, it is often necessary for the operator to insert his finger into the patient's anus, and after groping for the probe, bend it and take it out of the anus, which increases the patient's painful experience; The internal opening often encounters closed internal opening, that is, pseudo-healing or blocked pipeline. As a result, it is difficult to find the correct internal opening, and the thread hanging cannot be performed. Perhaps an incision operation is performed first, which increases the pain of the patient; (4) after thread hanging due to Pain, the patient's anus is always in a state of contraction, so that the wound outside the anus cannot be completely released, and the wound that has been strangled is often adhered together quickly, resulting in poor drainage of the external opening and easy recurrence of the fistula; (5) Exploring The rubber band connected to the needle is easy to fall off and break. The former increases the difficulty of the operation, while the latter requires 2 operations; (6) In some anal fistulas, the coil needs to be gradually tightened according to the degree of tissue necrosis, and eventually the tissue in the coil is completely necrotic , the coil then falls off

However, the steps of tightening the coil are cumbersome, which can easily lead to the breakage of the rubber band, resulting in the failure of the operation

[0005] In addition, when thread-hanging therapy is used to treat anal fistula, there is often a gap between the fistula opening and the hanging thread. When the patient defecates, dirt enters the fistula through the gap, affecting healing, and even causing more serious inflammation and abscess. pain
