Failure of Soft Biological Tissues Inserting of Needles

This research aims the failure of soft biological tissues in context minimally invasive surgery based on numerical analysis that fits experimental results. Using robotic arms for assistance medical procedures during last years led to new trends development devices inserting needles into tissues, as well expansion studies types needles. A better understanding mechanical interaction between a tool and tissue requires not only detailed investigation testing but also study evaluation characteristics effect needle geometry process. The purpose this first is investigate properties force reaction at necessary aspects performing FEA with results correlation data.
