Abstract
A needle adaptor (10) for connecting a needle (20) to an electrosurgical tool (56). The adaptor (10) includes a stem 12, an integrally formed post (14) and a collar (16) press-fitted on the stem (12). An annular ridge (50) or a spiral ridge (54) formed on the interior surface (32) of the collar (16) grips the flange (42) of the needle hub (22) to firmly hold the needle (20) in place on the post (14). The stem (12) is sized and shaped to be slidably received within a cylindrical terminal (64) positioned in the nose portion (60) of the electrosurgical tool (56).
