摘要/Abstract

摘要：

仿耻骨式人造肛门括约肌系统(PAAS)采用经皮能量传输(TET)为集成在充电模块内部的锂电池进行充电,使系统可长期稳定地在活体内工作.很多体内实验表明,无线充电过程中产生的大量热量对PAAS植入后充电模块附近活体组织的生物安全性不利,故需对无线充电过程进行合理规划.本文通过分析充电模块内部各组件的热传导关系,建立充电模块内部热阻模型,并利用体外实验对该模型进行验证及修正,经修正后的模型可以可靠地描述充电过程中活体组织温度变化情况.基于修正后的模型,本文制定了体内实验过程中单次最大连续无线充电时间,从而提高体内实验中PAAS的生物安全性,进而延长PAAS植入时间.

Abstract:

The puborectalis-like artificial anal sphincter system (PAAS) uses transuctaneous energy transmission (TET) to charge lithium batteries integrated within the charging module. Therefore, the system can work stably during in-vivo experiments for a long period of time. Massive in-vivo experiments show that the large amount of heat generated in the wireless charging process is unfavorable to the biological safety of the living tissue near the charging module after PAAS implantation, so it is necessary to reasonably plan the wireless charging process. In this paper, by analyzing the heat conduction relationship of the internal components of the charging module, the internal thermal resistance model of the charging module is established, verified, and modified by in-vitro experiments. The modified model can reliably describe the temperature changes of the living tissue during charging. Based on the modified model, this paper formulates the single maximum continuous wireless charging time during the in-vivo experiment, thus improving the biological safety of PAAS during in-vivo experiments, and then prolonging the implantation time of PAAS.

Key words: artificial anal sphincter, transcutaneous energy transfer, thermal resistance analysis, in-vivo experiment
