Deformation by mutual action of virtual internal organs and instruments both represented as visco-elasto-plastic materials

Abstract

The dynamic characteristics of the virtual system are discussed for the medical application. The internal organs synthesized by visco-elasto-plastic materials have interactions in consideration of their distortion and destruction caused by virtual tools. The operation of blood vessel by a thin plate-like and a hollow-cylindrical object with oblique edge were synthesized as a knife and a blood needle, respectively. The motion of the virtual tools in twist, rotation or parallel movement was also examined on their operation of virtual tissues and organs.
