Trepanning Head Clamp
Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives via Old French via Medieval Latin from the Greek noun of relevant meaning trypanon, literally "borer, auger") is a surgical intervention in which a hole is drilled or scraped into the human skull, exposing the dura mater to treat health problems related to intracranial diseases. Trepanning tools are rare but can be found in most good medical collections. What makes this device so interesting is the head clamp crank combination. Included in the gallery is an original watercolor using this device as a model.
