Abstract
A clip supports an elongated electrode within a nozzle of an electrosurgical handpiece used in gas electrocoagulation. The clip is preferably formed from a cylindrical tube which has been deformed into a configuration which has a central conduit-like section which engages and supports the electrode and two opposed conduit-like lobe portions which extend outward and slightly compress against the nozzle to hold the electrode and clip in place in the nozzle. The clip is formed by deforming a segment of a cylindrical tube into the clip around the tube. The clip and the attached electrode are inserted into the nozzle by resiliently compressing the clip by inserting a narrow end of the clip into a rear end of the nozzle and pushing the clip and the nozzle together, thereby resiliently compressing the clip as it slips into the nozzle.
