基于经皮供能的反馈式人工肛门括约肌系统研究

his paper proposes a new artificial anal sphincter with sensor feedback powered by transcutaneous energy transmission. This artificial anal sphincter is aimed to cure patients who are in servere anal incontinence or to replace the enterostomy. It consists of two components. One is taken outside with patients. The other is implanted into the bodies of patients and it is powered by transcutaneous energy transmission. The two parts communicate with each other through wireless communication. There are two sensors in the component implanted into the bodies. One detects the pressure in the cuff-clamp the recta. The other detects the pressure of the recta. As soon as the later pressure reaches the threshold, an alarm signal is sent out to notice patients to prepare for defecating through wireless communication. Patients can give the start signal to begin defecating after they are ready. They can also give the stop signal to stop defecating. Patients can defecate as healthy persons.
