摘要：

As an implantable medical device, the transcutaneous wireless energy transmission (TET) system of biaxial actuated artificial anal sphincter (BAAS) after implantation in vivo is affected by the hyperplasia of the parcel. The coupling performance is obviously lower than that of in vitro experiments, which reduces the practical value in medical treatment. Based on the experimental results of the TET system of BAAS, mainly aimed at the problem of transmission angle caused by the hyperplasia of the parcel, the existing TET system is analyzed and studied, and the relation curve between transmission angle and transmission efficiency are obtained. The experimental results show that when the transmission distance is 30 mm, the transmission efficiency reaches more than 60%. When the transmission distance is 30 mm and the transmission angle is 20°, the average transmission efficiency of the experiment can reach 66.65%. When the transmission angle is 30°, the average transmission efficiency of the experiment can reach 59.96%. The maximum of charging temperature of the transmitting coil is 23 ℃, which will not cause low temperature scald to the human body. It can meet the performance requirements of the BAAS system and achieve the purpose of long distance and high efficiency transmission. © 2022 Shanghai Jiao Tong University. All rights reserved.
