Within the digestive organ surgery robot R&D project, our research team aims to develop a surgical robot training device with an interface identical to that of the actual device. The training device uses an organ model that changes shape in real time to train operators to grab, cut open, and cut off soft tissues and close wounds using the actual device. To increase the effectiveness of the training device, we added functions to save the movements of the robot in training and changes in the operation field. By recreating the situation during training, we were able to analyze in four dimensions (4D) various changes in the operation field that the operator cannot see during training. This new function not only enabled us to analyze the contents of the training in detail, but also to report any problems in development and design of the actual device.
