Abstract In order to get to the desired target inside the body, it is essential to investigate
the needle-tissue coupling process and calculate the tissue deformation. A cantilever
beam model is presented to predicting the deflection and bending angle of flexible needle
by analyzing the distribution of the force on needle shaft during the procedure of needle
insertion into soft tissue. Furthermore, a finite element (FE) coupling model is proposed
to simulate the needle-tissue interactive process. The plane and spatial models are created
to relate the needle and tissue nodes. Combined with the cantilever beam model and the
finite element needle-tissue… More >
