Abstract :
The article establish a physical modeling of flexible needle biopsy soft tissue based on ABAQUS software, the model include material model, finite element model,mesh, and boundary constraint conditions etc. We carry out simulation and experiment for flexible needle biopsy imitate human tissues through the model. Finally, we analyzed the results of stress and deformation between the organization and needle in the interaction process.
