Technique for incorporating an electrode within a nozzle
First Claim
1. A clip for supporting an elongated electrode within a nozzle which directs a flow of gas from an electrosurgical handpiece, comprising:
- a central section having opposed and facing surfaces adapted to frictionally engage and extend longitudinally along an electrode and support the electrode in a predetermined position within the nozzle; and
a plurality of legs connected to the central section and extending transversely outward from the central section, said legs adapted to contact the nozzle and position the central section within the nozzle at a location spaced from the nozzle.

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.

13. A clip for use in supporting an elongated electrode within a cylindrical nozzle which directs a flow of gas from an electrosurgical handpiece, comprising:
-
three laterally adjacent partially closed conduits having coplanar centerlines, the conduits adapted to extend from one point on a circumference of the cylindrical nozzle to a diametrically opposed point on the circumference of the cylindrical nozzle, wherein the three partially closed conduits include; a central partial conduit having opposed and facing arcuate surfaces adapted to engage the electrode; and two lobe-shaped partial conduits extending from opposite sides of the central partial conduit and adapted to contact the diametrically opposed points on the circumference of the cylindrical nozzle, the lobe-shaped partial conduits adapted to allow gas within the nozzle to pass both around and through the lobe-shaped partial conduits. - View Dependent Claims (14, 15, 16)

17. A nozzle and electrode assembly to be used in conjunction with a handpiece for supplying electrical energy and gas from an electrosurgical apparatus to perform conductive gas electrocoagulation, comprising:
-
an elongated cylindrical nozzle adapted to apply the gas to a patient; a clip which is separate from the nozzle and which is inserted into and frictionally retained within a rear end of the nozzle, the clip including a central partial conduit having opposed and facing arcuate surfaces and two lobe-shaped partial conduits extending from opposite sides of the central partial conduit to contact an interior circumference of the cylindrical nozzle at diametrically opposing points; and an elongated electrode retained between the arcuate surfaces of the central partial conduit, the electrode extending within the nozzle along a longitudinal axis of the cylindrical nozzle. - View Dependent Claims (18, 19, 20, 21)
