碩士 === 國立中正大學 === 機械工程學系暨研究所 === 99 === In this thesis, knee arthroscopic surgery training system-an application of virtual reality technology, is developed to perform efficient, low-cost, high-quality virtual training that meets the requirements of doctors’ training needs. The advantages of knee arthroscopic surgery include small wound, less bleeding, faster recovery, etc, so it becomes the mainstream surgical approach at present. However, it requires high technical level and long-term training to become a chief physician of the arthroscopic surgery. Experience-based virtual surgery training system, compared to traditional training methods, has the advantages of high efficiency learning and low cost. Therefore, this thesis presents an experience-based virtual knee arthroscopic training system that records experiences by tracking the 3D operation trajectories of the experienced physicians. These trajectories are matched with the three-dimensional virtual model of the knee that is established from the patient’s medical images. In addition, with force feedback, the system can effectively guide the operator step by step to complete the inspection. The system is also open to evaluating the performance of the operator being trained. The operator can view their scores based on the study results, and develop experience by repeated practices to achieve proficiency and stability in the actual clinical examination. Experiments show that the proposed system, through the guided force to follow trajectories of the experienced physicians, can efficiently shorten the learning curves of the young doctors. Repeated training using this system can develop the skills required for arthroscopic surgery and can reduced the patient’s risk in the actual surgery.
