Research on Cholecystectomy Virtual Surgery Simulation Training Platform

Abstract

Abstract: The main performance factors in virtual surgery system with immersion are real-time, realistic deformation and smooth feel handle. A kind of cholecystectomy simulation training platform with force feedback feel was built, putting forward a kind of collision detection method based on Capsule-Sphere mixture model of different model with different bounding box in the real-time and a kind of mass-spring deformation method based on mesh-skeleton model in the force-deformation, and being tested on the virtual surgery force feedback device in prophase research. The experimental results show that the two modes are applied to the virtual cholecystectomy simulation and the platform can simulate the real-time realistic soft tissue deformation process and stability force feedback feel.

Key words: virtual surgery, force feedback, collision detection, deformation
