3维CT图像导航的并联机构辅助股骨复位方法

3D CT Image-Guided Parallel Mechanism-Assisted Femur Fracture Reduction

  • 摘要: 临床上传统股骨复位手术存在复位精确度不高、辐射量大等不足.针对以上不足,提出一种基于术前CT图像引导,由固定于股骨患侧上的6自由度并联机构辅助股骨复位的方法.该方法基于人体的对称性原理,用患者健侧股骨镜像作为标准,指导患侧股骨复位;通过执行机构上的12个标记点,在虚拟空间中实时标记执行机构上每根杆的长度.动物骨实验验证了此复位方法的有效性.

     

    Abstract: Traditionally,the clinical femur fracture reduction surgery is imperfect and often results in misalignment and high intraoperative radiation exposures.To solve the problem,a method for fracture reduction based on preoperative CT image and 6 degrees of freedom parallel mechanism which is fixed to unhealthy femur is proposed.Based on the body's symmetry principle,the method uses contralateral femur as a standard to guide the reduction of femoral shaft fractures.By twelve markers on the implementing machine/the computer can calculate the length of pole in the virtual space in real time. Finally,animal bones experiments show the effectiveness of the approach.
