Abstract

The invention discloses a novel artificial anal sphincter with double uniform radial clamping, which relates to the technical field of medical apparatus and instruments, and comprises a knob type control shaft, a transmission mechanism and blades, wherein the knob type control shaft drives the blades to rotate through the transmission mechanism. According to the invention, the intestinal tract is uniformly clamped in the radial direction through circular contraction, meanwhile, excreta leakage is avoided through double clamping, and the problems that due to the fact that loads applied to the intestinal tract by an existing artificial anal sphincter are not uniform, the intestinal tract is subjected to avascular necrosis, and excreta leaks in the clamping process are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel artificial anal sphincter device with double uniform radial clamping. Background technique [0002] Anal incontinence, also known as fecal incontinence, refers to the dysfunction of the anorectal continence and defecation mechanism. Although anal incontinence is not a life-threatening problem, it can cause physical and mental pain and seriously interfere with the normal life and work of patients with fecal incontinence. According to related reports, the prevalence of fecal incontinence in adults is 11%-17%, and the prevalence is similar between different genders, and it increases with age. [0003] Currently, there are general treatment and surgical treatment for the treatment of fecal incontinence, and the general treatment includes drug treatment, laxative treatment, biofeedback treatment, and radiofrequency anal sphincter remodeling. Among them, radiofrequenc...
