Minimally invasive surgical techniques using catheter is now used in many procedures. Development of surgical training of such procedures requires real-time simulation of tool-organ interaction. In such processes, each subsequent step of interaction would be based on the current configuration of the surgical tool (guidewire in this case), leading to development of techniques to solve and visualize the configuration of tool at every time step. This paper presents a Finite Element (FEM) based approach to simulate the tool-organ interaction.
目前，许多手术都采用了使用导管的微创手术技术。此类手术的外科培训发展需要对工具与器官的相互作用进行实时模拟。在这样的过程中，相互作用的每一个后续步骤都将基于手术工具（在这种情况下是导丝）的当前配置，从而促使开发出在每个时间步解决并可视化工具配置的技术。本文提出了一种基于有限元（FEM）的方法来模拟工具与器官的相互作用。
