A mechanistic force model for simulating haptics of hand-held bone burring operations

Virtual reality (VR) interfaces integrated with haptic devices are increasingly being used in medical training to simulate surgeries [1 –3]. Haptic devices use algorithms based on a force rendering model to calculate forces experienced during the manipulation of soft and hard tissues. However, creating realistic haptic feedback is challenging for operations involving biological material removal because of the varying position and orientation of the cutting tool and the highly dynamic and non-linear material responses, as opposed to simple elastic contact and deformation of the object.
