We present a mechanics-based haptic simulation of an arbitrary suturing task for a simple skin or a soft tissue wound closure. The pre-wound suturing target, the skin or the deformable tissue, is modeled as a modified mass-spring system. The suturing material is modeled based on the linear finite-element model with some novel extensions for enhancing the computation of the constrained mechanics models. Novel extensions to typical suturing models are defined. For example, if the needle incision points are too close to each other or from the edge of the wound and if the user pulls on the suture with a force which is beyond a predefined threshold, the suture will tear the soft tissue instead of suturing the incision. Experiment results show that our simulator can run on a standard desk-top computing environment and allow the user to perform different suturing patterns with smooth haptic feedback.
