计算机辅助膝关节置换手术系统的设计

目的:设计一种膝关节置换手术辅助系统,模拟出患处组织及假体三维结构,辅助医护人员制定手术方案。方法:系统采用网络分层与.NET开发技术,以开源图像软件开发包ITK及VTK为基础,模拟患处三维结构并进行定量测量,估算出患处与假体空间位置,为临床提供辅助决策信息。结果:系统在手术过程中显示出组织及假体位置、距离等信息,为膝关节置换手术操作者提供了辅助信息,也为医患沟通及交流提供了新的方式。结论:该系统既可助于改进膝关节假体的设计,使其更符合膝关节复杂的形态学,从而减少假体-骨界面的松动发生率,又可有助于了解手术进程并直观掌握组织与假体材料之间的位置,及时制定或修改手术方案。

Design of Computer-aided knee replacement surgery system

Abstract] Objective： To design an assistance systems of knee replacement surgery, which is able to simulate the 3D structures of the tissue and the prosthesis, auxiliary medical staff surgical plan. Methods： The system uses a network layered with .NET development technologies based on open source imaging software development kits ITK and VTK, which has a simulation of the affected area 3D structure and quantitative measurements to estimate the spatial location of the lesion with the prosthesis to provide decision support for health care workers information. Results： The system not only shows that during surgery the tissue and the prosthesis position, distance, knee replacement surgery operation auxiliary information, but also provides a new way for the doctor-patient communication and exchange. Conclusion： One hand the system can both help to improve the design of knee prosthesis and make it more consistent the knee complex morphology, thereby reducing the prosthesis - bone interface loosening incidence; On the other hand, help to understand the surgical process and intuitive master position between tissue and prosthetic materials, help to develop or modify the surgical plan, which provides a good reference for the adjuvant treatment of similar diseases.
