当前脊柱手术方案制定方式无法适应复杂的临床环境与高风险控制需求,本研究为实现安全、个性化手术规划目的,开发了计算机辅助椎弓根螺钉植入系统。首先,系统根据图像预处理结果,利用面绘制技术重建脊柱模型。然后结合二维像素擦除与多平面切割技术,提出新的脊椎骨分离算法,去除因各骨块间存在冗余连接而产生的计算偏差。最后,系统提取选定参考平面与分离骨块的相交轮廓曲线,实现椎弓根螺钉置入手术过程的直观模拟。实验结果表明:该系统可以精确地完成脊椎骨模型的分割,并快速直观地完成椎弓根螺钉的虚拟置入,为医生设计手术方案提供科学依据。

To achieve the goal of safety and personalization for surgery planning, a computer system aiding pedicle screw implantation was established in this paper, as the present spine surgery planning method does not meet the needs of complex clinical environment adaptability and high risk controllability. Firstly, the spine model was reconstructed based on its pre-processed images by surface rendering technology. Secondly, combined with the technology of 2D pixel erasing and 3D multiple surface cutting, a new vertebra dividing algorithm was offered and the deviation caused by redundancy between bone connections was removed. Finally, the contour line of where the selected reference surface was abstracted and the bone cros was separated and the process of pedicle screw implantation surgery was directly simulated. The results demonstrate that the system can precisely achieve spine bone model segmentation and virtualize pedicle screw implantation effectively, where it provides scientific basis for surgical planning.
