1. An electrosurgical electrode, comprising:
an electrically conductive main body including:
a curved segment;
a first planar outer surface configured for tugging tissue; and
a second planar outer surface, opposite the first planar outer surface, configured to coagulate the tissue; and
an electrically conductive blade fixed to the first planar outer surface along at least the curved segment of the electrically conductive main body, the electrically conductive blade having a distal-most end extending from the first planar outer surface proximal to a distal-most end of the electrically conductive main body in a direction away from the second planar outer surface, the electrically conductive blade configured to cut the tissue being tugged by the first planar outer surface.
