Abstract	In this paper, the simulation of soft tissue deformation in real-time virtual surgical systems is introduced and analyzed and physics engine is lead to solve the contradiction between the precision of simulation and real time in computing of soft tissue deformation. A real-time soft tissue deformation module based on the physics engine PhysX is designed in this paper. In this paper, a tetrahedral mesh production algorithm is used to generate finite element models, which can describe the soft tissue details, and a linear viscoelastic model(Kelvin model) is used to replace simple linear elastic model, which can generate viscoelastic finite element model and improve the biofidelity of virtual surgery. Furthermore, using smooth particle hydrodynamics module to simulate blood, the real-time interaction between soft tissue and blood is implemented.
