面向植入式医疗器械的人体运动学分析方法综述

随着植入式医疗器械的大量使用,其安全性受到广泛关注。植入式医疗器械出现故障,力学原因被认为是其失效的一个重要因素,日常活动中微小而反复的力学载荷会造成植入式医疗器械元件的疲劳损坏。获取并研究典型日常活动的人体重点解剖部位的运动信息,对植入式医疗器械的设计及手术方案的优化具有积极意义。本文概括了人体运动学研究的3种方法以及日常活动模拟动作的选取,介绍了该领域的最新进展及问题,并展望了有价值的研究方向。

Overview of body kinematics analysis for implantable medical devices

Since implantable medical devices （IMD） are widely used all over the world,its security and stability are more and more focused on.Mechanical factors are considered one of the important causes,small yet reiterative mechanical loads may lead to damages on IMDs elements.As a result,measurement and analysis on the sport information of key anatomic sites in daily living activities are helpful to optimize IMDs＇ designing and implanting plan.Three research methods of human body kinematics and simulation of daily activities are summarized,and the latest developments in this field are introduced.Then the paper points out the issues that need to be improved and prospects valuable research directions.
