Abstract
In this paper, we describe the development of a surgical simulator for brain tissue pushing operation using a brain spatula. It is important to present tactile sensation in surgery simulator, so our main aim is to provide surgeons with a tool which can teach them the correlation between deformation and applied force. For this purpose, smoothing the discrete reaction force is significant. So we discuss about contact model that occurs multi-point collision between the brain spatula and brain tissue, and verify the availability of the development system.
