Treppanning is a very ancient form of surgery and as you can guess, the most noticeable in pre history context. I have made a Roman drill but do not have a photo, I have specialised in ancient medical instruments, you would be surprised at how advanced there were. One instrument is the cataract needle Acvs as well as the crouching one that is also used,

And also the Clyster,

Enema syringe, using good old castor oil. The list is endless of the amazing engineered equipment they came up with which are still used today.
This a beauifuly made Specvlvm

Used in child birth. From Pompeii 1st AD.
