Abstract: In recent years, the virtual surgery training system with force feedback has provided a new way for young doctors to improve their surgical skills in a safe, efficient and flexible training method. Precise drilling force and realistic hand feeling of manipulation are the cruxes in the virtual surgery training, and the accurate simulation of bone drilling depends on the accurate establishment of drilling force prediction model. The establishment of force prediction model with finite element analysis is the key part in the development of virtual training system. In this paper, the current research status of finite element analysis of bone drilling presented in four aspects: bone model reconstruction, material model, mesh model and prediction of drilling force, especially the construction of bone tissue material model is discussed in detail and several important models are analyzed. This paper presented a relatively complete overview of the approaches commonly used in this research field to promote the establishment of more accurate force prediction models of bone drilling.

Key words: virtual surgery training system, force prediction model, finite element analysis, bone drilling
