An electrosurgical 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.

An electrical connector achieves improvements in connecting a patient plate to an electrosurgical generator. The connector is preferably of the lever operated type, and electrical contacts are connected on the lever and connected within a passageway internally in a housing of the connector. A tongue portion of the patient plate is inserted in the passageway. Upon closure of the lever, the contacts on the lever extend into the passageway above the lower contacts to mechanically contact and retain the tongue portion between the contacts and to electrically contact the tongue portion by which to conduct current to the patient plate. A recess is formed in the lower marginal area of the passageway and a retaining structure on the lever member extends into the passageway to deform the tongue portion into the indention. The electrical contacts are spacially separated and electrically interconnected to provide an upper and lower electrical contact point for the tongue conductor which is electrically insulated from another spacially separated upper and lower electrical contact point.
