Electrosurgical wand and related method and system
First Claim
1. An electrosurgical wand comprising:
- an elongate housing that defines a handle end and a distal end;
a connector comprising a first and second electrical pins;
an aspiration aperture on the distal end of the elongate housing, the aspiration aperture fluidly coupled to a first fluid conduit, the first fluid conduit within the elongate housing;
a discharge aperture on the distal end of the elongate housing, the discharge aperture fluidly coupled to a second fluid conduit, and the second fluid conduit within the elongate housing;
a first active electrode of conductive material on the distal end of the elongate housing, the first active electrode between the discharge aperture and the aspiration aperture, and the first active electrode electrically coupled to the first electrical pin; and
a conductive plate that abuts the discharge aperture, at least a portion of the conductive plate disposed over the discharge aperture, and the conductive plate electrically coupled to the second electrical pin.
