In Saw 3 a sequence is shown where Dr. Lynn Denlon performs a operation on John (Jigsaw) using a drill and other similar tools. My first question is, how can they perform an operation where hardware tools are used rather then medical instruments? Also, how can a person speak during his open brain surgery? My second question is, is there any similarity between this operation sequence and reality? |

I have not seen the movie so I have not seen the tools themselves. However operations which require cutting bone often require tools which might at first glance look like conventional power tools, such as drills and small circular saws. Tools designed for operations are designed to be very controllable in terms of speeds and the cutting implements themselves are made of high quality materials to prevent contamination, but essentially they are not that far removed from hardware tools. In terms of being awake during surgery. The main reason to anaesthetise a patient in an operation is to prevent the pain and stop any movement which would disturb the operation. The scalp itself has pain receptors but the brain has none, once the work has progressed into the brain itself no pain from that part would be felt, but with a local topical anaethetic the scalp might not be too painful. One could imagine that you could be awake but not be in much discomfort in a brain operation. |
