[Spider Man 2] Why was there a mini-chainsaw in the operating theater?

Hey all,

Why did the surgeons have a presumably battery-powered mini-chainsaw in the operating theater where Otto Octavius aka Doctor Octopus was going to have his set of tentacled metal arms removed? Given chainsaws aren't designed or made to cut metal.

That's not a chainsaw (no chain), it's an electric bone saw.  Normally the teeth on this thing would sheer off if you used it on metal. 

This one is probably using a carbide blade or something to cut through the octopus arms.  They have them handy in the ER for when they need to cut away impaled objects, like steel rods or bicycle frames.

It doesn't need batteries -- it plugs in.
