A virtual reality based arthroscopic surgery simulator

The minimally invasive approach of arthroscopy means faster recover and less pain for the patient than that of open surgery, but the skills required by the surgeon are radically different. Although a number of arthroscopic training techniques are available, all have problems with cost, availability, etc. Virtual reality based training system has been proofed a promising technology in many fields including pilot training. In recent years, virtual reality technique found its application in endoscopic surgeries. In this paper, a virtual reality based training system is presented. Mechanical design, kinematics, dexterity measure and control loop of the haptic device are investigated. Organ mesh generation, tissue deformation simulation and collision detection are also discussed. Finally a virtual reality based arthroscopic surgery simulator is developed. Testing and evaluation results for the prototype training system, was very positive and satisfactory.
