Bone drilling haptic interaction for orthopedic surgical simulator

Multipoint Collision Detection Algorithm for Bone Milling and Drilling in a Haptic VR Surgery Simulator

Comparison of cadaveric and isomorphic virtual haptic simulation in temporal bone training

BACKGROUND Virtual surgery may improve learning and provides an opportunity for pre-operative surgical rehearsal. We describe a novel haptic temporal bone simulator specifically developed for multicore processing and improved visual realism. A position locking algorithm for enhanced drill-bone interaction and haptic fidelity is further employed. The simulation construct is evaluated against cad...

Realistic Haptic Interaction in Volume Sculpting for Surgery Simulation

Realistic haptic interaction in volume sculpting is a decisive prerequisite for successful simulation of bone surgery. We present a haptic rendering algorithm, based on a multi-point collision detection approach which provides realistic tool interactions. Both haptics and graphics are rendered at sub-voxel resolution, which leads to a high level of detail and enables the exploration of the mode...

Visuohaptic Simulation of Bone Surgery

We present techniques for the visual and haptic simulation of bone surgery, with a specific focus on procedures involving the temporal bone and the mandible. We discuss our approaches to graphic and haptic rendering and interactive modification of volumetric data, specifically focusing on generating force-feedback effects that are relevant to bone drilling. We then discuss how our rendering pri...

Elements of virtual temporal bone surgery: Manipulandum format may be more important to surgeons than haptic device force capabilities

Background Temporal bone simulations are critiqued for poor drill-bone interaction. This project appraises the import of increasing haptic device and manipulandum fidelity on the perceived realism of drilling a virtual temporal bone.Virtual surgical contact forces rely on haptic device fidelity and are transmitted through a manipulandum. With identical software, both device hardware and manipul...
