The computer-assisted spine surgery system presented in this paper follows the basic ideas which have been developed for computer-assisted medical interventions (CAMI) in our lab since 1985. There are three steps to insert a linear tool inside vertebral pedicles. First, the surgeon defines an optimal trajectory on pre-operative computed tomography. Second, this trajectory is reported in the operating room coordinate system using an intra-operative sensor and a registration algorithm. Third, a guiding system helps the surgeon follow the selected trajectory. In this paper, we present an implementation of this method that uses only a 3-dimensional optical localizer. Results on cadaver specimens and on the first seven patients are presented.
本文介绍的计算机辅助脊柱手术系统遵循了自1985年以来我们实验室为计算机辅助医疗干预（CAMI）所开发的基本理念。将线性工具插入椎弓根内有三个步骤。首先，外科医生在术前计算机断层扫描上定义一条最佳轨迹。其次，使用术中传感器和配准算法将该轨迹报告到手术室坐标系中。第三，引导系统帮助外科医生遵循选定的轨迹。在本文中，我们展示了仅使用三维光学定位器的该方法的一种实现方式。文中给出了在尸体标本和前七名患者身上的结果。
