Gammerstang commented on the word trocar
(noun) - (1) A cane, or pipe made of silver, or steel, with a sharp-pointed end, us'd in tapping those that are troubled with the dropsy. --Edward Phillips' New World of Words, 1706 (2) An instrument used for evacuating fluids or gases from cavities. It consists of a perforator or stilet, and of a cannula tube which is so adapted to the perforator that when the puncture is made both enter the wound with facility, after which the stilet being withdrawn, the cannula remains in the wound and affords the fluid a ready passage outwards. --Robley Dunglison's Dictionary of Medical Science, 1844 (3) The handle of the trocar is of wood, the cannula of silver, and the perforator of steel. --Samuel Sharp's Treatise on the Operations of Surgery, 1747
