TAPERED PRECISION BLADE ELECTROSURGICAL INSTRUMENT

摘要

An electrosurgical electrode comprises an elongated body having a cross-sectional area and longitudinal side edges forming longitudinal cutting edges adapted for electrosurgical dissection along a plane. The body has a configuration, wherein: the thickness of the side edge is less than or equal to 0.01″, forming only one cutting edge, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.000150 in2 per cutting edge; or the thickness of a first side edge is greater than 0.01″ and the thickness of a second side edge is less than or equal to 0.01″, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.001 in2 per cutting edge.

主权项

1. An electrosurgical electrode adapted for use in performing electrosurgical operative procedures, the electrode comprising:
an elongated body extending longitudinally between a first end and a second end, the body being formed of a conductive material and adapted to be electrically connected to an electrosurgical generator to facilitate communication of electrical energy from the generator to the electrode for communicating radio frequency electrical energy to patient tissue for performing electrosurgical operative procedures thereupon, the body having:
one or more longitudinal side edges extending between the first end and the second end, at least one of the one or more longitudinal side edges having a thickness less than or equal to 0.01 inches, the at least one of the one or more longitudinal side edges comprising one longitudinal cutting edge;a cross-sectional area; anda cross-sectional area-to-number of longitudinal cutting edges ratio that is less than or equal to 0.000150 square inches per longitudinal cutting edge.
