Abstract

In order to improve the?accuracy of operation process of?needle?puncture in?virtual?operation ,we complete finite element?simulation?of ?the?typical soft tissue --liver?puncture, based on the?experimental data?and result of ?puncture real?soft tissue. Because of?the diversity?of human tissue, and the complexity of?the biomechanical properties from?soft tissues, according to the comprehensive?consideration of the material and the?mechanical properties of the soft?tissue, in this paper, we abstracted the?liver parenchyma as Mooney-Rivlin?materials, combining with deformation mechanism of ?soft tissue by stress, complete contrasting between real experiment?and simulation?based on MATLAB. It can be seen in the comparison of the curve, stress-strain curve from simulation results by ANSYS is similar with the?real data. It verify ?the effectiveness and ?the feasibility for liver puncture experiment by finite element simulation.
