    摘要: A device is disclosed for simultaneous cutting and cauterizing of tissue. The device comprises a cutting edge of a blade. The blade defines a channel within the blade wherein the outlet end of the channel is near the cutting edge. A catalyst is disposed near the outlet end. The channel carries a gaseous mixture to the catalyst where the mixture reacts in the presence of the catalyst and generated heat. The heat generated cauterizes blood vessels as the blade cuts through tissue.
