1. An electrode assembly for an electrosurgical pencil, comprising:
an insulative core configured to support an active wire around a peripheral surface of the insulative core, the active wire electrically coupled to an active pin adapted for insertion within a distal end of the electrosurgical pencil;
a ground electrode operably coupled to a proximal end of the insulative core and adapted for insertion within the distal end of the electrosurgical pencil;
an insulative material disposed between the active pin and the ground electrode and configured to at least partially encapsulate and electrically isolate the active pin from the ground electrode; and
a hypotube operably engaged to a proximal end of the insulative material and configured to at least partially encapsulate the active pin, wherein the ground electrode surrounds the hypotube and the insulative core.
