A simulation method of soft tissue cutting with haptics

Simulation of soft tissue cutting is a problem. For proposing an effective simulation method, a surgery simulation system is put forward, and a double thread software system which contains graphics thread and equipment thread is built in the research. And ball-spring model is used as the internal physical model of the surgery object to realize the force feedback and the deformation. And then a surface model associated with the physical model is built. Based on the physical model and the surface mesh, an effective cutting algorithm is put forward. The simulation results proved that the proposed calculation model can effectively achieve the real-time cutting interaction and deformation of soft tissue, and real-time force feedback can be acquired. In conclusion, the model proposed can realize the simulation of the soft tissue cutting process.
