Surgeons are required to implement sufficient training for performing laparoscopic surgery. The objective of this study is to develop a training system so that trainees can train surgical operation of ligation by themselves without any instructions by skilled surgeon. First, difference of the surgical skill between skilled surgeon and intern surgeons is investigated by watching surgeon's forceps operation. As a result, it turned out that the amount of rotation of the wrists by intern surgeons is not as large as that of skilled surgeon in wrapping procedure of ligation. Second, a system to evaluate effective forceps operation of the right and the left forceps is proposed for the wrapping procedure in ligation, in which trainee's skill is evaluated on the basis of the amount of rotation of the skilled surgeon's wrists and the required time in the wrapping procedure performed by the skilled surgeon. In addition, an interface for representing the evaluation results to the trainee was also developed. Third, in order to verify an effectiveness of the proposed evaluation method, experiments for investigating the distinction rate of the wrapping procedure performed by skilled surgeons and the wrapping procedure performed by intern surgeons were carried out. Finally, the sensor module that can be attached to the forceps was developed for angular measurement in the realistic surgical environment and was applied to in vivo experiments.
