| 摘 要： | 脑起搏器(Deep Brain Stimulator,DBS)是一种针对帕金森病非常有效的方法,但目前的脑起搏器普遍存在电池需频繁更换的问题,增加了患者的负担。外置式脑起搏器(EDBS)克服了传统脑起搏器电池电量受限的缺点,将信号发生部分移出体外,减轻了患者手术更换电池的痛苦。然而外置式DBS附着在患者体外的部分有可能随着患者的日常活动产生移位,影响使用效果。本文设计了自对准装置,利用永磁体对磁性材料的吸引作用使传递信号的两个线圈保持相对固定的位置,使整个系统维持一个较高的耦合效率。

| Abstract: | Deep brain stimulator(DBS) is the most effective therapy for Parkinson's Disease(PD), but the limitation of power supply made patients suffer much to replace battery.External deep brain stimulator(EDBS) overcame this disadvantage by removing neurostimulator out of patient's body.Two coils were utilized to transmit pulse, one inside the patient's body while the other outside.However, coils would fail to aim at each other during the patient's activities of daily living.This paper is to present an auto-magneti... |
