Abstract

BACKGROUND:

It is important to develop a new kind of implantable artificial anal sphincter system to meet the physiological needs of the human body.

OBJECTIVE:

To design a new kind of implantable artificial anal sphincter system.

METHODS:

Wireless communication model and pressure sensors were used to rebuild the mechanism of defection, and the power was supplied with transcutaneous energy transmission model. The electro-mechanical system was adopted to simulate the human natural organ to achieve the control efforts of human anal sphincter finally.

RESULTS AND CONCLUSION:

A new kind of implantable artificial anal sphincter system was designed and accomplished. The bio-feedback control ability of anus incontinent patients could be recovered in some degree based on the reconstruction of defecation mechanism and model. The implantable artificial anal sphincter system had the module of transcutaneous energy transmission that could provide long-time wireless power for the internal system. The animal experiment was accomplished to verify the feasibility to implant the implantable artificial anal sphincter system and its basic function.
