【摘要】 传统的全膝置换手术存在着夹具种类繁多、操作繁琐、股骨力学难以确定等问题。本文设计了一套新型的适用于全膝置换手术的装夹具 ,包括可调式的支撑臂及伺服电机驱动机械臂 ,并在实验室中搭建了计算机辅助全膝置换手术系统。实验证明该结构不仅彻底地解决了困扰传统机器人辅助手术中患者腿部的固定装夹问题 ,而且整个系统结构紧凑 ,大大地方便了医生的手术干预更多还原

【Abstract】 Conventional Total Knee Replacement(TKR)surgery is difficult to manipulate with a series of jigs and fixtures and hard to align the mechanical axis of femur.In this paper,a computer aided surgical system for TKR is developed in laboratory,which consists of articulated manipulator and mechanical support arm driven by the servo motor. The performance of prototype shows that the compact mechanisms solve the above problem absolutely and lead convenience to surgeons.更多还原
