Anal fistula seton device

Abstract

The invention discloses an anal fistula seton device, belonging to the technical field of medical apparatus. The anal fistula seton device comprises a seton device body, a traction piece and a drainage wire; a guide hole is arranged at the center of the seton device body along the length direction, a nose-shaped bending part is formed at one end of the seton device body, and a release ring chambercommunicated with the guide hole is concavely arranged on the nose-shaped bending part; the traction piece is placed in the guide hole, one end of the traction piece is provided with a drainage wirechucking lug, while the other end of the traction piece is provided with a release ring which is used for pulling the traction piece out of the guide hole after the pick-up of an operator, wherein therelease ring is in a shrinkable state when locating in the guide hole and in a release state when reaching the release ring chamber; the drainage wire is connected with the drainage wire chucking lug. The invention has the advantages that the anal fistula seton device can be adaptable with a seton operation curve; stoma can be ensured to be completed once, thereby avoiding unnecessary wound to patients; the anal fistula seton device is favorable for causing the tissue in the seton to be cut off from a near end, and can provide a tension stringing reference for an operating surgeon, thereby ensuring the specification and standard of the tension stringing process.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a thread hanger for anal fistula, which is a surgical supporting device for carrying out thread hanging treatment when drainage or strangulation is required in the treatment of high perianal abscess or high anal fistula. Background technique [0002] A fistula is a tube formed when an abscess occurs in a human or animal body. The tube opens or communicates with other internal organs on the surface of the skin, and the secretions in the lesion can overflow through the fistula. Anal fistula is one of the intractable diseases in the field of anorectal surgery. For the above-mentioned high perianal abscess or high anal fistula surgery, not only requires the surgeon to have good skills, but also requires rich surgical experience. For a long time, domestic and foreign scholars A lot of energy has been poured into the research of such diseases, among which the anal f...

Problems solved by technology

However, the plan does not provide the technical measures of how to send the elastic thread into and pull it out, which is not enough to make people realize that the above-mentioned structure is conveniently and practicably applied to the patient's disease site. It can work under the action of gravity, so the elastic tension of the elastic thread cannot be consistent, so that continuous strangulation cannot be achieved, and it may even cause paroxysmal pain in patients, resulting in poor cooperation and unacceptable conditions.
