Abstract
Surgical scissors having argon plasma coagulation capability are shown. The surgical scissors include in their body a channel for receiving a flexible tube having a wire within it. The flexible tubing and wire within it are connected to a generator that provides electrical energy to the wire and argon or other inert gas to the tube. The flexible tubing travels a portion of the length of the scissors and ends with a coaxial connector in the proximity of the cutting edges of the scissors. An argon plasma coagulation sleeve is placed on the cutting end of one or both sides of the scissors and is connected to the flexible tubing and wire through the coaxial connector. Each sleeve has one or more ports for discharging electrified argon gas that coagulates tissue.
