The artificial anal sphincter is used to simulate the normal operation of the anal. It can solve the anal incontinence and relieve patients’ life and psychological pressure. The artificial anal sphincter system proposed in the paper is based on a novel executive mechanism. The novel executive mechanism uses a hinge structure to clamp the rectum. To ensure the mechanism’s reliability, a mechanical model between the novel executive mechanism and rectum is established to predict the deformation of the rectum when compressed in the radical direction. The results show that the deformation can be controlled by adjusting the spring force.
