| Abstract: | A simulation system for arthroscopic knee surgery was introduced and the methods of related techniques such as system structure design, fast collision detection, deformations of soft tissues and real-time force feedback calculation were discussed. A collision detection algorithm based on axis-aligned bounding boxes hierarchies of octree and an elastic finite element semi-implicit model were proposed. Combing force feedback calculation, four kinds of arthroscopic knee surgery were simulated. By application, this system can satisfy the requirement of clinic surgery training. |
