Hi, there is definitely some potential here. Another of our users made a Dental Surgery Simulator (

However, that's probably the limit of what you can do - i.e. PolyVox won't handle soft tissue, stress, strain, fracture, etc. It's just a maching cubes implementation for visualising the volume data.
Also, PolyVox is only working on volume data, so if you have mesh data then you would need to convert it. This might not be trivial.
If you give some more detail of your project then maybe I can give further information.
