Patent attributes
An electrode assembly for an electrosurgical pencil includes an insulative core configured to support an active wire around a peripheral surface thereof and a ground electrode coupled about the insulative core and adapted for insertion within an electrosurgical pencil. A hypotube is disposed between the ground electrode and the active pin and encapsulates the active pin to insulate the active pin from the ground electrode. An active pin is included that is adapted for insertion within the pencil and has a tensioning assembly including: a set screw with threads that engage grooves of the active pin such that, upon rotation, the set screw advances to secure the active wire within the active pin; and a nut is fixed within the hypotube that includes grooves that engage threads of the active pin such that, upon rotation, the active pin translates proximally to tension the active wire about the insulative core.
