An electrosurgical wand. At least some of the illustrative embodiments are electrosurgical wands configured as a surgical forceps including opposed legs that defines respective distal end portions, the legs of the forceps operable to be actuated between an open position and a closed position, an active and return electrode disposed on one of the respective distal end portions, a discharge aperture on one of the distal end portions coupled to a first fluid conduit, and an aspiration aperture through the return electrode on the other of the distal end portions fluidly coupled to a second fluid conduit. In embodiments, the position of the forceps' legs, and the electrical energy applied to the electrodes, is adjusted to provide dissection or coagulation to the tissue. A stop or latch on the forceps' legs may maintain the active and return electrode a fixed distance from one another.

Plasma bipolar forceps

The present disclosure includes an electrosurgical apparatus for treating tissue at a target site. The apparatus has a shaft with a proximal end and a distal end, and the distal end includes an active disposed laterally on the shaft distal end and return electrode. The return electrode may have a plurality of apertures through it, which are fluidly connected to a fluid delivery element, operable to deliver a conductive fluid to the shaft distal end. The return electrode may encircle at least a portion of the shaft and may extend distally and proximally from the active electrode.
