摘要/Abstract

摘要：

作为植入式医疗设备的一种,双轴驱动式人造肛门括约肌(BAAS)系统的经皮无线供能(TET)系统在植入活体后,受到增生包裹等体内环境的影响,面临耦合性能明显低于体外实验的问题,降低了其在医疗中的实用价值.结合现有BAAS的TET系统实验结果,针对受增生包裹导致的传输角度等问题,对现有TET系统的参数进行分析研究,得出了传输角度与传输效率的关系曲线.实验结果表明,在传输距离为30 mm时,传输效率仍可达到60%以上.在传输距离为30 mm条件下,传输角度为20° 时,传输效率的均值可达到66.65%;传输角度为30° 时,传输效率的均值可达到59.96%.发射线圈充电温度最大值为23 ℃,充电温度不会对人体造成低温烫伤的情况,满足BAAS系统性能要求,达到了在传输距离较远时仍可高效率传输能量的目的.

Abstract:

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.
