摘　　要：针对反馈式人工肛门括约肌的供能问题，研究经皮能量传输系统原理，并研制出经皮能量传输系统，使得反馈式人工肛门括约肌能够模拟实现人体排便功能。通过实验分析接收端负载以及两线圈位置偏移对传输效率的影响，验证了系统的传输性能。实验结果表明，研制的经皮能量传输系统在发射和接收线圈轴向距离为15mm条件下，能稳定传输超过400mW功率，传输效率可达10％，保证人工肛门括约肌的正常工作。The principle of transcutaneous energy transmission was studied, and a transcutaneous energy transmission system was designed for the energy supply of reactive artificial anal sphincter, which enables the reactive artificial anal sphincter to realize the defecation function of human body. The experiments analyzed the relationship between transmission efficiency and the load of the receiving end, and the two coils＇ position displacement as well. More than 400mW could be steadily received in the experiments with transmission efficiency of 10% at the axial separation of 15mm, which would guarantee the normal work of artificial anal sphincter.
