Abstract

Surgery simulation is one of the largest applications of Medical Virtual Reality. In order to perform the real-time simulation, we constructed an elastic organ model known as a sphere-filled model. This proposed organ model allows us to perform surgical maneuvers such as pushing, pinching and incising and show the deformation of the inner structures such as blood vessels on our system. In addition, we tried to obtain haptic sensation with the patients' organs in a surgical simulation. Developed system made it possible to handle elastic organs with two force feedback devices attached to the both of users' hands. At the same time, we have been developing a VR cockpit suited for virtual surgery and tele-surgery. Using our VR cockpit, our system allows us to provide the users with an environment closely resembling the open surgery situation.
