Abstract
It is necessary to perform sufficiently training in the laparoscopic surgery, however, the traditional training method is based on the skilled surgeon guidance. The objective of this study is developing a training system which can train surgical operation of ligation without any skilled surgeons' advices. First, difference of the operation features between skilled surgeons and intern surgeons is analyzed by measuring surgeon's hand positioning and the loaded force to the axis and the handle of the forceps. As a result, it is found that the amount of rotation of the wrists by skilled surgeon's operation is not as short as that by non-skilled surgeon's operation at wrapping in ligation. Secondly, an evaluating system for effective forceps operation of the right and the left is proposed on the basis of the amount of rotation of the wrists by skilled surgeon at wrapping in ligation and the time required for performing the wrapping in ligation. Then, the data at the wrapping in ligation is sampled by observing the trainee's operation movie. Finally, an interface for representing the evaluation results to the trainee is developed.
