我们描述了一个正在进行的合作项目，以开发一个计算机集成系统，以帮助外科医生在锡永全髋关节置换手术RTHR在RTHR手术中，一个失败的骨科髋关节植入物通常是通过移除旧的植入物，移除骨水泥，并将一个新的植入物放入股骨中扩大的髓腔中来替换。该项目的目标是显着减少骨水泥移除劳动力，本文以Robodoc为出发点，首先讨论了计算机集成的人工髋关节置换手术系统和人工RTHR手术方案的主要困难，RTHR和识别关键问题和可能的解决方案我们然后描述了一个新的系统架构，用于术前规划和术中执行，并提出了一个增量开发策略，使系统的手术室我们总结了初步结果报告，在CT伪影消除机器人和图像配准规划与电子表格的X射线和CT图像交互式水泥切割体积定义和骨水泥加工
We describe an ongoing collaborative e ort to develop a computer integrated system to assist surgeons in revi sion total hip replacement surgery RTHR In RTHR surgery a failing orthopaedic hip implant typically ce mented is replaced with a new one by removing the old implant removing the cement and tting a new implant into an enlarged canal broached in the femur The goals of the project are the signi cant reduction of cement removal labor and time the elimination of cortical wall penetration and femur fracture the im proved positioning and t of the new implant resulting from precise high quality canal milling and the re duction of bone sacri ced to t the new implant Our starting points are Robodoc a computer integrated system for primary hip replacement surgery currently in clinical trials and the manual RTHR surgical proto col We rst discuss the main di culties of computer integrated RTHR and identify key issues and possible solutions We then describe a new system architecture for preoperative planning and intraoperative execution and propose an incremental development strategy to bring the system to the operating room We conclude with a report of preliminary results in CT artifact re moval robot and image registration planning with a spreadsheet of X ray and CT images interactive ce ment cut volume de nition and cement machining
