Research Abstract

In this study, we proposed new measurement and analysis methods of visceral organs, especially hollow organs such as stomach and intestine for developing surgical simulators. Then we established a database of biomechanical characteristics in order to publish for researchers. Besides, we have implemented a new surgical simulator based on the obtained data in this study.
