Design and research of simulated surgical instruments for medical training system

For the purpose of helping new doctor master surgical technique, improving the successful rate of surgery, also for reducing the training cost of surgery, according to real-world surgery condition, three operative instrument simulators applied in surgery training were designed based on degree of freedom numbers of three operative instruments. Operator of those simulators can feel feedback force from simulators. Work spaces of the simulators were analyzed. The results shows that three simulators meet the design requirements and their work space were the same as that of real operative instruments. The simulators can exactly be used to simulate specific operative instruments in surgical training system.
