| titleOfInvention | Electrosurgical gas attachment |
| abstract | A circuit (10) concurrently activates a gas flow control valve (15) and electrosurgical generator (11) from an electrosurgical pencil (13). An automaticswitch (16) receives current flow upon the operation of the energy request button (12) by the surgeon. The switch connects to the gas surgical unit (26) flow control valve (15) operating it to control inert gas to the pencil. An electrode (32) and nozzle combination (30) transports ionizable gas to a tip (31) on the pencil for gas enhanced electrosurgery on a patient. An electrode (32) has proximal and distal ends (34) with a length (35) between and along an axis. A shroud (36) surrounds the electrode (32) along its length (35) leaving the proximal and distal ends (34) exposed. A patient part (37) on the shroud (36) points toward the patient. A rear part (38) on the shroud (36) points toward the rear or the pencil. The parts align substantially along the axis so a passage (39) between the parts defines a space(40) within the shroud (36) and about the length (35). A port in the shroud (36) has a lumen (42) protruding therefrom at an angle to the axis. The lumen (42) connects with the passage (39) for fluid communication. An end cap (43) attaches to the proximal end (33) for surrounding the electrode (32) and for forming a gas tight seal between the proximal end (33) and the rear part (38) of the shroud (36). A complimentary portion (44) on the rear part (38) and an anti rotation lock (45) on the end cap (43) engage to prevent relative rotary motion. An anti twist posterior (46) on the end cap (43) interengages with the pencil to prevent relative rotation. The anti twist posterior (46) and the pencil each have hexagonal interengaging features thereon. The shroud (36) and end cap (43) are of polymers that can be injection and overmolded, respectively to the electrode (32). A method makes a gas tight seal between a shroud (36) and an electrode (32) by injection molding then fixturing the electrode (32) without contact with the shroud (36). Overmolding an end cap (43) to the shroud (36) attaches the electrode (32) and to form the seal. |
