Three-dimensional finite element modelling for soft tissues surgery

Abstract Laparoscopy is a surgical technique that requires fine control from the surgeon point of view. Up to this day, this experience can only be obtained by intensive training. That is why a lot of training simulators have been developed in the medical area. We present here a new approach based on a three-dimensional finite element software and an elastic constitutive equation, able to predict realistic results. This software has been applied to soft tissues deformation, namely lamb kidney and human uterus, and the numerical results are compared to experimental ones.
