US Patent 11779394 Single-sided low profile end effector for bipolar pencil

An electrode assembly for an electrosurgical pencil includes an insulative core configured to support an active wire around a peripheral surface thereof, the active wire electrically couples to an active pin that inserts into a distal end of the pencil. A ground electrode is operably coupled about the insulative core and inserts within the distal end of the electrosurgical pencil. An insulative material is disposed between the active pin and the ground electrode and is configured to at least partially encapsulate and electrically isolate the active pin from the ground electrode. A first hypotube is disposed atop the insulative core and extends along between the ground electrode and the insulative core, the first hypotube encapsulates the active wire to insulate the active wire from the ground electrode. A second hypotube is operably engaged to a proximal end of the insulative material and is configured to encapsulate the active pin.
