Abstract
An electrosurgical electrode for coagulating and cutting tissue includes a main body fabricated from a conductive material, and a conductive blade extending inwardly from an inner surface of the main body. The blade has an edge configured to concentrate RF for cutting tissue.
Claims20
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.

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 receive a first electrosurgical waveform for coagulating tissue;
- and
- a blade fixed to the first planar outer surface along at least the curved segment and configured to receive a second electrosurgical waveform different than the first electrosurgical waveform, wherein the blade has a distal-most end that projects 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 to form an edge configured to concentrate electrosurgical energy from the second electrosurgical waveform for cutting the tissue.
