For tele-robotic surgery, immersive view or precise view of operating field with live video streaming is indispensable. However, the given view is limited in viewing angle, quality, and resolution by the ability of instruments. Video streaming delay is unavoidable by the limitation of the network. The purpose of this report is to research the main factor of difference between skillful operators and skill-less operators under telesurgery environment.
By the experiment, the skill of subjects was evaluated in the target-pointing task on the Surgical Cockpit System. The subjects were classified into skillful group and skill-less group by frequency of mistakes. Accuracy of posture of surgical instrument, time for task operation, and total path length of surgical manipulator were compared between two groups.
The main difference was shown in the total movement. Total path length was significantly short, moreover, the path length was not varies under different conditions. The difference between skillful subjects and skill-less subjects were enlarged by the video streaming delay.
