摘要：
In order to make the surgery simulation more physically realistic, a novel symmetric board-spring model for real-time haptic rendering is proposed, which can be used to deal with the nonlinear changes of soft tissue produced frequently in virtual surgeries. With PHANTOM OMNI, a haptic interactive experimental system has been established, which realized the interaction that virtual forceps stretch normal heart tissues and heart neoplasms. Experimental results indicate that this model is easy to calculate, convenient to simulate stretching, and effective to imitate the whole stretching process of soft tissues dynamically. Compared with the current models, the proposed model can make the sense of haptic more stable, and the simulation more realistic in interactive process and satisfy the needs of the real-time interaction in virtual surgery simulation.
