Abstract:The existing artificial anal sphincter system cannot supply stable, long-term and safe way of energy, which greatly reduces its practical value in medical treatment. The transcutaneous wireless energy transmission of the artificial anal sphincter system in this article can achieve the system′s energy supply. Combined with the biaxial actuated artificial anal sphincter system, mainly aimed at the short transmission distance and serious heating problems of the existing TET, the existing coil wire diameter, the number of turns, the shape of magnetic core, and the coil structure, transmission distance between the transmitting coil and the receiving coil and other parameters are optimized. Experimental results show that when the transmission distance is 20 mm, the transmission efficiency could reach 77. 64% . When the transmission distance is 30 mm, the transmission efficiency could achieve 52. 59% . The charging temperature of the optimized transmitting coil is reduced by 55. 6% . The optimized parameters could meet the performance requirements of the biaxial actuated artificial anal sphincter system and provide theoretical basis and data support for future research.
