| 摘 要： | 针对股骨颈复位微创手术复位精度低,手术失败率高的问题,在研究C臂透视成像的基础上,基于MicronTracker双目视觉传感器研制了一种新型视觉导航系统.建立了系统数学模型,在Matlab中对模型进行了仿真,采用蒙特卡罗法对误差来源进行了分析,根据系统误差分析结果提出了误差控制策略.针对股骨生理解剖结构提出了股骨颈空心钉手术规划方法,同时系统给出了手术环境的视频信息,实时监控双目视觉传感器跟踪状况.通过相关的临床实验,验证了该手术导航系统的可行性.

| Abstract: | A new type of visible light video navigation system was developed based on the research on the C arm tomography. The micron Tracker binocular visual navigation equipment was used to acquire the position information of surgical instru- ment.The mathematic model of the system was established and simulated in Matlab.The origin of errors was analyzed with the Monte Carlo method and the error control strategy was presented according to the error analysis result.The surgi- cal planning based on close reduction an... |
