Suturing simulation in surgical training environment

In this video we present a physics-based haptic simulation designed to teach basic suturing techniques for simple skin or soft tissue wound closure. The pre-wound suturing target, skin or deformable tissue, is modeled as a modified mass-spring system. The suturing material is designed as a mechanics-based deformable linear object. Tools involved in the live suturing procedures are also simulated. Collisions between the soft tissue and the needle, the soft tissue and the suture are analyzed. In addition to modeling the detail steps involved in a typical suturing procedure, modeling approaches for evaluation of a stitch are also discussed.
