Abstract

The invention discloses an adaptive middle swing arm structure and a puborectalis muscle-like double-ring praeternaturalis anus sphincter prosthesis thereof. The puborectalis muscle-like double-ring praeternaturalis anus sphincter prosthesis comprises the adaptive middle swing arm structure, an upper fixed ring, a lower fixed ring, a connection bracket, a minitype motor and a gear reduction gearbox, wherein the upper fixed ring and the lower fixed ring are arranged in parallel and are implanted into the periphery of an intestinal tract to be fixed and are respectively arranged on two ends of the connection bracket; a swing arm body, the minitype motor and the gear reduction gearbox are all in integrated arrangement with the connection bracket; the minitype motor is meshed with a gear transmission device by the gear reduction gearbox. The adaptive middle swing arm structure has the advantages of small size and light weight, damage to tissues around the intestinal tract by an actuator is further lightened, and a prosthesis implantation success rate can be improved.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to an adaptive middle swing arm structure and a puborectalis-like double-ring artificial anal sphincter prosthesis. Background technique [0002] Fecal incontinence is a common clinical disease. According to statistics, the incidence rate of adults is as high as 2%, and the incidence rate of people over 65 years old can reach 7%. In fact, the incidence of this disease is often caused by patients being ashamed to seek medical treatment. underestimated. Fecal incontinence means that the anal sphincter loses its ability to control the excretion of feces and gas. It can easily cause a variety of complications, which not only bring great pain to patients, but also bring many difficulties to nursing work. Development, fecal incontinence has become one of the diseases that urgently need to be solved clinically. [0003] Severe fecal incontinence is caused by the loss ...
