An electrosugrical unit 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 includes a nozzle which is releasably connected to a handle for easy manipulation by a surgeon with the nozzle including means for supporting an electrode in an optimal position for initiation of the ionization of the gas. Also, a connecting system is disclosed for connecting the hose on which the handle is mounted to a gas delivery apparatus and supply or electrical energy which permits the hose to rotate while maintaining a positive hermetic seal to prevent the hose from kinking during use by a surgeon.
