摘　　要：手术仿真系统可以进行新的手术方式的培训、也可以用来预演手术的整个过程以便事先发现手术中的问题。作为一个特殊的VR系统 ,手术仿真系统要求能够对手术过程中的切割和缝合进行模拟 ,本文提出了一种基于局部处理的软组织切割算法 ,可以较好地完成对于以四面体作为基元的有限元模型的实时切割任务。Surgery Simulation System can be used to train surgeon to adapt for new operational methods,and also it can be used to preview the process of operation so as to discover some unpredicted problem. As one kind of specialized VR system,Surgery Simulation System aimed at simulating all the possible interactions during a real operation,which include cutting and suturing. This paper presents a soft tissue cutting algorithm. The algorithm processes Element model which composed of tetrahedrons,and can be employed in real time Surgery Simulation Systems.
