Shaped electrode bipolar resection apparatus, system and methods of use

摘要

An electrosurgical instrument is provided and includes a housing configured to connect to a source of bipolar electrosurgical energy and an electrode body coupled to the elongated housing. The electrode body includes an electrode face, first and second bipolar electrodes and a blade. The electrode face is formed on the distal end of the electrode body and includes a longitudinal axis and a transverse axis therethrough. The first and second electrodes have a leading edge and a trailing edge, are formed on opposite sides of the longitudinal axis and connect to opposed electrical potentials. The blade is positioned between the electrodes with at least a portion of the blade extending beyond the electrode face.

1. An electrosurgical instrument, comprising:
a housing defining a longitudinal axis, the housing configured to connect to a source of electrosurgical energy; and an electrode body coupled to the housing, the electrode body including:
an electrode face formed on a distal-most end of the electrode body, wherein the entire electrode face defines a plane that is perpendicular to the longitudinal axis, the electrode face having a leading edge and a trailing edge and defining a centerline extending from the leading edge to the trailing edge transverse to the longitudinal axis of the housing;first and second electrodes positioned parallel to and on the electrode face; wherein the first and second electrodes are formed on opposite sides of the centerline and configured to connect to opposed electrical potentials; anda blade positioned between the first electrode and the second electrode, and movable to extend at least a portion of the blade distally beyond the electrode face.
