Abstract EN
In the present work, the majority of implemented virtual surgery simulation systems have been based on either a mesh or meshless strategy with regard to soft tissue modelling.
To take full advantage of the mesh and meshless models, a novel coupled soft tissue cutting model is proposed.
Specifically, the reconstructed virtual soft tissue consists of two essential components.
One is associated with surface mesh that is convenient for surface rendering and the other with internal meshless point elements that is used to calculate the force feedback during cutting.
To combine two components in a seamless way, virtual points are introduced.
During the simulation of cutting, the Bezier curve is used to characterize smooth and vivid incision on the surface mesh.
At the same time, the deformation of internal soft tissue caused by cutting operation can be treated as displacements of the internal point elements.
Furthermore, we discussed and proved the stability and convergence of the proposed approach theoretically.
The real biomechanical tests verified the validity of the introduced model.
And the simulation experiments show that the proposed approach offers high computational efficiency and good visual effect, enabling cutting of soft tissue with high stability.
