Abstract: Burring surgery is mainly implemented for fine or critical
structures and widely used in orthopedic, oral and maxillofacial, ENT and
neurosurgery departments to delicately cut or polish bones, joints or other
tissues. This paper describes a volume manipulation method that extends a voxel
with multiple values to represent accurate burred changes on tissue surfaces.
Tissue surface reconstruction is implemented for the local burred surface to
provide a real-time visual response. A burring force vector for a haptic
response is calculated by detecting which parts of a bur contact tissue and
summated from tissue removal loads on the contacted parts. A spine surgery
example showed that rough surface features by gross cutting or smooth features
by fine cutting can be clearly demonstrated and high haptic reality can be
achieved by our simulations. The burring surgery simulator with the accurate
visual and haptic responses can be an effective rehearsing and training
tool.
