2P1-B04 Skill Assessment of Super Microsurgery by Measuring the Manipulation of Tweezers(Medical Robotics and Mechatronics)

Abstract

A skill assessment system has been developed to quantify microsurgical skills. Infrared optical makers, an inertial measurement unit and strain gauges were mounted on tweezers to record surgical tasks, and a preliminary experiment was conducted. The trajectory, hand tremor and applied force during a suturing task were measured, and the results showed significant differences between skilled and novice surgeons. During the anastomotic task, skilled surgeons manipulated the needle with much smaller force once the needle penetrated the artificial blood wall. Further analysis will be conducted to extract the motion elements unique to the skilled surgeon so that surgical training systems and intelligent surgical robots can be developed.
