In this study, the skill difference between an experienced surgeon and a beginner in forceps manipulation during laparoscopic surgery is discussed. To clarify the difference between an experienced surgeon and a beginner, experiments with a sensor forceps were carried out. In the experiments, the suturation was performed as an example of the skilled operation. Applied force for the operation of the forceps and manipulated motion of the forceps were measured at the same time. The experimental results show that the orientation of the forceps, shaft forces, the moving distance and so on are different between an experienced surgeon and a beginner. The results would be an important index to train the skills in laparoscopic surgery with the surgery simulator.
