A kind of method and its system for simulating microtrauma puncture operation

The invention provides a kind of method and its system for simulating microtrauma puncture operation, the data message for treating operative site can accurately be obtained by scan image data, ensure the accuracy of Surgery Simulation operating environment, and independently model lesion body and tissue, Surgery Simulation scene is combined with real scene using augmented reality, enhance the sensory experience of user, it is easy to during sham operated, operator is when point of puncture is found, surrounding's important blood vessels situation of accurate observation tissue, it is easy to training operator accurately to know point of puncture, improve successful surgery probability；Simultaneously, the application is in collision detection process, by the interactive segmentation between virtual operation instrument and virtual human body tissue into two stages, build the soft tissue deformation stage respectively and puncture the force feedback equation in stage, received output using force feedback equipment, it is accurate to perceive current operation active force so as to operator is in simulated experiment operating process so that experiment feeling of immersion enhancing.
