This paper presents a comprehensive survey on the modeling of tissue cutting, including both soft tissue and bone cutting processes. In order to achieve higher accuracy in tissue cutting, as a critical process in surgical operations, the meticulous modeling of such processes is important in particular for surgical tool development and analysis. This review paper is focused on the mechanical concepts and modeling techniques utilized to simulate tissue cutting such as cutting forces and chip morphology. These models are presented in two major categories, namely soft tissue cutting and bone cutting. Fracture toughness is commonly used to describe tissue cutting while Johnson-Cook material model is often adopted for bone cutting in conjunction with finite element analysis (FEA). In each section, the most recent mathematical and computational models are summarized. The differences and similarities among these models, challenges, novel techniques, and recommendations for future work are discussed along with each section. This review is aimed to provide a broad and in-depth vision of the methods suitable for tissue and bone cutting simulations.
本文对组织切割建模进行了全面综述，包括软组织和骨组织切割过程。作为外科手术中的关键过程，为了在组织切割中实现更高的精度，对此类过程进行细致建模对于手术工具的开发和分析尤为重要。这篇综述文章聚焦于用于模拟组织切割的力学概念和建模技术，如切割力和切屑形态。这些模型主要分为两大类，即软组织切割和骨组织切割。断裂韧性通常用于描述组织切割，而在骨组织切割中常采用约翰逊 - 库克材料模型并结合有限元分析（FEA）。在每一部分，都总结了最新的数学和计算模型。同时，在每一部分还讨论了这些模型之间的异同、挑战、新技术以及对未来工作的建议。本综述旨在对适用于组织和骨组织切割模拟的方法提供广泛而深入的见解。
