The growing interest in laparoscopic hernia surgery and in surgical simulation has motivated our current research. In this report, we present our work in simulating the process of stapling used in a laparoscopic herniorrhaphy procedure. By connecting two separate deformable meshes together, our model has also simulated the repair process of a bilateral hernia correction performed using a preperitoneal mesh. The task of mesh placement and stapling of corners was simulated to allow surgeons to practice their hand-eye coordination. Simple collision detection models sufficient for our task were developed and demonstrated. Various deformable models and numerical methods were researched to comply with the real time requirements. A phantom device was used for a haptic-based force feedback design during task rehearsals. Several 3D instruments were modeled to support user interaction with the objects in the scene.
