Abstract

The realistic modelling of medical interventions is the key requirement for development of high-fidelity medical simulators. In this work, a parameterized model suitable for real-time haptic feedback of needle interaction with tissue has been developed. The FE based numerical simulations are performed in ABAQUS/CAE and Comsol and then the results are post-processed in MATLAB to develop the parametric model. The obtained parametric model validated through comparison with various literature results. A MATLAB based GUI App has also been developed that utilizes these results and delivers an interface to examine the desired forces for any known needle position/orientation.
