Abstract:

Virtual reality technology and force feedback technology are novel human-machine interaction technologies. The virtual surgery simulation training system combined with these two technologies provides a new method for orthopedic surgery training, which can improve the training efficiency, thereby reducing the training costs and shortening the growth cycle of young orthopedic surgeons. In recent years, the virtual drilling bone surgery simulation technology have been researched broadly and obtained a preliminary application. In this paper, the existing research status of virtual bone drilling operation depended on visuo-haptic techniques were studied, classified and summarized, the main content focused on three key techniques: bone modeling, drilling bone force prediction model and tactile simulation, and then analyzed the advantages and disadvantages of existing methods. Finally, some perspectives for related technology development trend of the virtual simulation bone drilling surgery in future was pointed out.

Key words: virtual surgery simulation, bone modeling, force prediction model, tactile simulation
