摘要：In view of the high failure rate of knee joint surgery and the difficulty of quantitative evaluation of knee joint stability, a robot system for knee joint stability evaluation is proposed. The system achieves the purpose of evaluating the stability of the knee by testing the biomechanical characteristics of the knee joint during the surgery. The system using electromechanical control technology and servo technology implement precise force / torque loading on the knee joint, relatively accurate measurement of micro displacement of knee joint of femur and tibia using vision measurement technology, this data as biomechanical characteristics of knee joint in order to assess the stability of the knee to. The model of bone experiment shows that this system can measure the biomechanical properties of knee joint accurately, the accuracy of measurement is high, at the same time, the system movement is stable, safe and reliable, has high value in clinical research.
