Abstract

Clamping and removal of the nucleus pulposus (NP) are critical operations during transforaminal endoscopic lumbar discectomy. To meet the challenge of simulating the NP in real-time for better training output, an improved material point method is proposed to represent the physical properties of the NP and compute its deformation in real time. Corresponding volume rendering of the NP and its hosting bones are also presented. The virtual operation procedures are then implemented into a training prototype and subsequently tested through simulation experiments and subjective evaluation. The results have demonstrated the feasibility of the approach.

基于优化物质点法的手术模拟系统髓核夹紧程序。
在经椎间孔内窥镜下腰椎间盘切除术中,髓核的夹持和取出是非常关键的手术。为了满足实时模拟NP以获得更好的训练输出的挑战,提出了一种改进的物质点法来表示NP的物理性质并实时计算其变形。并给出了NP及其宿主骨的相应体绘制。然后将虚拟操作程序实现到训练原型中,并通过仿真实验和主观评价进行测试。结果证明了该方法的可行性。
