摘　　要：人造肛门括约肌系统可以模拟人体正常肛门括约肌的工作,解决肛门失禁问题,缓解直肠切除病人的生活和心理压力。研究了人造肛门括约肌系统中的核心装置,提出了一种基于螺母丝杆结构的新型微泵,根据微泵的功率要求设计了无线能量传输模块,并进行了样机实验。测试结果表明该泵可以满足人造肛门括约肌系统的基本功能,该系统可以有效地控制肛门失禁问题。The artificial anal sphincter system can simulate the normal operation of the anal, thus solving the anal incontinence and relieving the psychological pressure of the patients with their rectum cut out. This article researches into the core operation part of the artificial anal sphincter system, introducing a novel micro-pump based on the nut and screw structure. It also presents the transcutaneous power transmission module according to the power required by the pump and measurement of the prototype. The test indicates that the pump can satisfy the basic requirement of the artificial anal sphincter system which can therefore control the anal incontinence.
