Cost-efficient suturing simulation with pre-computed models.

ABSTRACT

Suturing is currently one of the most common procedures in minimally invasive surgery (MIS). We present a suturing simulation paradigm with pre-computed finite element models which include detailed needle-tissue and thread-tissue interaction. The interaction forces are derived through a reanalysis technique for haptic feedback. Besides providing deformation updates and high fidelity forces, our simulation is computationally less costly.
