摘要：

Virtual reality (VR) based surgical simulation provides the best possible scenario and repeatable training for a surgeon. In this paper, a virtual simulation system for dynamic needle insertion is presented. First, a piece-wise nonlinear mass-spring model was used to simulate soft tissue material properties. Then a novel force algorithm was proposed by considering the effects of needle insertion velocity and needle diameter for haptic simulation. Finally, a practical needle insertion experiments were conducted, and the validity of the proposed method was confirmed by a comparison between the virtual feedback force from the simulation system and the practical needle insertion force.
