Volume Based Cutting Force Simulation for Musculoskeletal Surgery

Abstract

Volume based surgical simulation typically provide visual verification of surgical plans; however, cutting force prediction allows a surgeon to verify feed rates and paths of surgical tools. In this paper, we present several force computation models used in musculoskeletal surgeries to evaluate bone cutting. Forces on surfaces of a virtual surgical tool are computed to simulate the instantaneous force on the tool that can be oscillating or rotating. The virtual tool is triangulated and rendered with isosurfaces of tissues. Overload surfaces of the tool are highlighted to indicate abnormal feed rate and moving paths of the tool.
