Description

technical field

[0001] The invention relates to a system belonging to the technical field of medicine, in particular to a biofeedback artificial anal sphincter system. Background technique

[0002] Defecation is mainly controlled by three factors, that is, the appropriate pressure of the anal sphincter: the anal sphincter maintains an appropriate pressure, which can prevent feces from flowing out of the rectum; the storage capacity of the rectum: the rectum has the function of expanding and storing feces. There is a sense of defecation; the rectum has a normal sensory function: it will convey the sense of defecation to the brain, and perform defecation behavior. Once there is a problem with any of the above three factors, it is easy to cause fecal incontinence. Anal incontinence refers to the obstacle of controlling defecation ability, which is one of the common diseases in anorectal surgery. Especially for some patients whose rectum and part of the colon have been resecte...
