Back on topic. We know its not a print duplicator, rock sampler, 3D protractor. It is a Surgical instrument, but not used to insert something under bone or biopsy the brain.
Is this one of those dealios (technical term) that they would use for a MacGyverish facial reconstruction from a skull?
Maybe it's a guide for a drill. like when you need to get through the cranium for a frontal lobotomy.
It was used as a guide, but not for a drill or a lobotomy. Surgeons used this device to 'locate' something that needed to be removed.
Is that what happened to my other half of a brain? I've always bragged about my IQ....it's 70...not too shabby for only half a brain !!!
