手术模拟器为手术培训提供了一种安全且潜在有效的方法，也可用于机器人辅助手术的术前和术中计划。手术器械和器官之间相互作用的精确建模已被公认为是开发高保真手术模拟器的关键要求。研究人员试图以各种各样的方式对工具-组织相互作用进行建模，这些方式可以大致分为（1）基于线性弹性的方法，（2）基于非线性（超弹性）弹性的有限元（FE）方法，以及（3）不基于FE方法或连续介质力学的其他技术。器官变形的真实建模需要用真实的组织数据（其难以在体内获取）填充模型并在真实的时间（其在计算上是昂贵的）中模拟器官响应。此外，在侵入性外科手术过程中，由于工具-组织相互作用而导致的支撑器官的结缔组织、摩擦和拓扑变化是具有挑战性的。克服这些障碍将不仅有助于我们在真实的时间内对工具-组织相互作用进行建模，而且还能够在手术模拟期间向用户提供逼真的力反馈。本文对现有的手术模拟器工具-组织相互作用的研究进行了分类，特别是基于所采用的建模技术和所模拟的手术操作的种类，以告知和激励未来的研究改进工具-组织相互作用模型。
Surgical simulators present a safe and potentially effective method for surgical training, and can also be used in robot-assisted surgery for pre- and intra-operative planning. Accurate modeling of the interaction between surgical instruments and organs has been recognized as a key requirement in the development of high-fidelity surgical simulators. Researchers have attempted to model tool-tissue interactions in a wide variety of ways, which can be broadly classified as (1) linear elasticity-based, (2) nonlinear (hyperelastic) elasticity-based finite element (FE) methods, and (3) other techniques that not based on FE methods or continuum mechanics. Realistic modeling of organ deformation requires populating the model with real tissue data (which are difficult to acquire in vivo) and simulating organ response in real time (which is computationally expensive). Further, it is challenging to account for connective tissue supporting the organ, friction, and topological changes resulting from tool-tissue interactions during invasive surgical procedures. Overcoming such obstacles will not only help us to model tool-tissue interactions in real time, but also enable realistic force feedback to the user during surgical simulation. This review paper classifies the existing research on tool-tissue interactions for surgical simulators specifically based on the modeling techniques employed and the kind of surgical operation being simulated, in order to inform and motivate future research on improved tool-tissue interaction models.
