Laparoscopic surgery is very difficult for surgeons and requires time and experience to master the technique, so an enhanced surgical navigation system is needed to assist the surgeon. In this research, we will develop a simulation system that displays the deformation of organs due to contact with surgical instruments calculated by the finite element method. A motion capture system is used to estimate the position of the tip of the surgical instrument and the contact target, and the images linked to the real space are drawn on the CG space to present the surgeon. First, the deformation caused by multiple surgical instruments was confirmed. After that, we simulated the deformation of organs by grasping and dissecting a model with separated label pairs and virtual springs, and confirmed the state of deformation.
