Surgical Animations

What I've been pondering these few weeks is how realistic a surgical animation can be. To reconstruct the entire ALND procedure might require a lot of effort in rendering realistic textures, as well as non-mechanical movements of muscle and fat.

Right now what I could gather from different sources are animations that are more systematic; they are realistically rendered, but somehow I feel that they're not as realistic as what I'm aiming for.

Perhaps I should venture out to other animation such as gaming...(zombies with dangling flesh anyone?)
