中文摘要	目的针对临床上膝关节置换手术中软组织平衡测量的需要,研究并开发了一种新的软组织平衡测量系统用于帮助医生在膝关节置换手术中软组织平衡的测量和调节。方法软组织平衡测量系统由测量装置前端、信号采集控制盒和便携式电脑组成。在置入膝关节腔中的前端测量装置上装有6个精密的微型压力传感器,分布在装置面板的左右、前中后6个位置,用于测量软组织张力大小。同时前端测量装置的上下平行面板的间距可通过机械传动装置完成增大和缩小的调节。结果本测量系统能够较好地完成膝关节之间软组织的张力大小测量、膝关节间距调节和张力大小的三维动态显示。结论结合软组织张力大小和膝关节间距数据,能对膝关节的动力学研究有更大的帮助。; Objective In order to meet the quantitative soft tissues balance measurement requirement in the TKR, a newsoft tissues balance measurement method and system have been developed to help surgeons measure and adjust thesoft tissue in the total knee replacement. Methods Six precise load sensors have been embedded in the measuredevice front, which will be inserted into the cutting gap of the knee joint, to measure the force of the surrounding softtissue. The pressures of these sensors represent the force of the posterior, middle, and anterior positions in the medial/lateral part of the knee joint gap. Furthermore, the device has the function that can change the distance between its upperand lower plate by the mechanical structure for adjusting the space in the knee joint. Results The preliminary testshows that the measurement system can accomplish the force measurement and the distance adjustment in the kneejoint, and display the data of the force distribution in three-dimensional manner in real-time. Conclusion It will be morehelpful for knee dynamics research to combine the data of soft tissue force with the data of distance between the knee joint.; 广东省自然科学基金博士启动基金资助(05300431); 上海市关节外科临床医疗中心和上海市卫生局课题资助(2006)
