ELECTROSURGICAL CONDUCTIVE GAS STREAM EQUIPMENT

摘要

An electrosurgical unit (40) for conducting a predetermined ionizable gas in a jet stream to the tissue at a predetermined flow rate sufficient to clear natural fluids from the tissue and to substantially expose the tissue stroma and for exposing the gas to an electrical radio frequency energy to ionize the gas in conductive pathways in the gas jet stream. The unit (40) includes a nozzle (52) which is releasably connected to a handle (76) for easy manipulation by a surgeon with the nozzle (52) including means for supporting an electrode (58) in an optimal position for initiation of the ionization of the gas. Also, a connecting system is disclosed for connecting the hose (48) on which the handle (76) is mounted to a gas delivery apparatus and supply of electrical energy which permits the hose (48) to rotate while maintaining a positive hermetic seal to prevent the hose (48) from kinking during use by a surgeon.
