Description
technical field [0001] The invention relates to a virtual surgical instrument, in particular to a multifunctional virtual surgical instrument applicable to a medical training system, which belongs to the field of medical training instruments. Background technique [0002] The development of modern science and technology increasingly embodies the intersection and penetration of multiple disciplines. The application of virtual reality in the medical field has made virtual surgery a growing research direction. Virtual surgery is to use various medical imaging data and virtual reality technology to establish a virtual environment, and doctors use the virtual environment to carry out surgical planning and training. Virtual surgery can help doctors formulate surgical plans; it can also be practiced repeatedly, reducing the cost of surgical training and shortening the cycle of training surgeons. The virtual surgery training system has the advantages of low cost, zero risk, multip...
