EXPERIMENTS AND SIMULATIONS FOR LAPAROSCOPIC VENTRAL HERNIA REPAIR IMPROVEMENT

The authors conducted a wide experimental and numerical study in order to determine effective approaches in the laparoscopic VH repair. At first the study covered identification of mechanical properties of the abdominal fascia, implants, tacks and transabdominalsutures. Basis on these data, the one and two-dimensional mathematical models were formulated and a number of numerical static and dynamic analyses were carried out. Then various physical models of the fascia-mesh system were built in many configurations, using a porcine fascia, a few kinds of implants and tacks.
