Abstract
With the current availability of advanced robotics and virtual reality technology, Surgical simulation has become one of the most promising areas in modern medicine. The paper proposes a novel desktop virtual surgical simulation system capable of not only surgical training but also operative planning, surgery rehearsal and telesurgery, which is mainly used on the robot-assisted orthopedic surgery system, FLIT-RAOS. The paper fist introduces the hardware system of FLIT-RAOS, then highlights the process of building the virtual environment. In the course of this process, firstly, Pro/E, Javd3D and VRML are chosen to built the virtual simulation models of each robot consisting of the surgery system, secondly, a novel and reliable finite element method is used to built the biomechanical human model of the leg, and accordingly the force-distance curve diagram is created through this model, then the virtual orthopedic surgery simulation system is gotten through integrating the robot models and the biomechanical model. Lastly, a teleoperation system for the surgery simulation is built to test the availability and real-time of this virtual surgery simulation system.
