Abstract	In order to ensure the real-time property of the virtual surgery system and improve the model rendering speed, we propose an acceleration collision detection algorithm based on invisible separated surface. Meanwhile, to reduce the local deformation and the loss of important information caused by virtual cutting maximally in the medical preoperative diagnosis and surgery planning, we propose a surface model cutting algorithm on the basis of removing the intersecting grid cell. Under the premise of ensuring the system's real-time property, the algorithm deals the triangle mesh with a series of operation like subdividing, projection and so on. The experimental results show that the collision detection method has improved the action speed of virtual equipment touching with the model surface. The cutting algorithm can be implemented easily and retain the original information better, which is expected to help to improve the accuracy of the diagnosis judged by the doctor according to the patient's condition.
