摘要：In virtual cardiovascular surgery, the force feedback is transmitted via the flexible guide wire. In the force transmission, disturbance always occurs due to flexible deformation, and this would make it hard to ensure immersion by rendering the force feedback in actuator. As the effect of flexible deformation is related to the length of guide wire, experiment is designed to assess the force transmission of guide wire when the length between the actuator and operating point changes. In this paper, three indexes are proposed to search for the length between the actuator and the device entrance. And the optimal scope length of guide wire is found out to ensure the guide wire has the best performance for the force transmission.
