Abstract

The invention provides a corrugated pipe injection type miniature pump for artificial anal sphincter in the technical field of medical instrument. The pump comprises a conduit, a corrugated pipe component, a miniature motor and a telescopic mechanism, wherein two ends of the conduit are connected with a forceps clip capsular bag and the corrugated component respectively; the corrugated pipe component and the telescopic mechanism are movably connected, and the insides of the corrugated pipe component and the telescopic mechanism are communicated; and the miniature motor is connected with the corrugated pipe component and the telescopic mechanism respectively. By being connected with the forceps clip capsular bag, the pump realizes liquid storage and bidirectional fluid discharge between the pump and the forceps clip capsular bag, and can realize pressure maintaining function at any position, so that the functions and the performance of an artificial anal sphincter control system can be improved.

Description

technical field [0001] The invention relates to a device in the technical field of medical instruments, in particular to a bellows injection micro pump for artificial anal sphincter. Background technique [0002] Anal incontinence refers to anorectal continence and defecation dysfunction, inability to control excretion of feces and gas at will, inability to perceive the volume and nature of rectal contents, and inability to control nighttime defecation. Although it is not life-threatening, it seriously affects the quality of life of patients. [0003] Artificial anal sphincter implantation can effectively control defecation, help patients regain control over their own defecation, eliminate the psychological shadow caused by anal incontinence, re-establish confidence in life, and improve their quality of life. As a technology that can bring good news to patients, the artificial anal sphincter has very good research and development prospects. [0004] According to the litera...
