Virtual Surgery: Simulating the Cutting and Manipulation of Soft Tissues

Today we train surgeons on the backs of the poor through
free clinics and low-income care. In the absence of computerized
training tools for predicting surgical outcomes, practitioners often
learn through their own mistakes limiting the quality of care they
can provide to their patients. I will present a framework for
simulating and predicting surgical outcomes involving cutting,
manipulating and suturing soft tissues. Such operations are
ubiquitous in surgeries like cleft-lip and palate repair,
cranio-facial reconstruction, burn scar contracture repair and tendon
transfer/musculo skeletal surgeries. Soft tissues are modeled as
hyperelastic deformable solids with the Finite Element Method and
robust and efficient implicit time stepping is used to allow for
maximal interactivity. A new "cutting" algorithm is used to rapidly
and efficiently separate material about an incision with minimal
remeshing.
