Electrosurgical wand and related method and system

摘要

Electrosurgical wand. At least some of the illustrative embodiment are electrosurgical wands including: an elongate housing that defines a handle end and a distal end; 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 a conductive plate that abuts the discharge aperture, at least a portion of the conductive plate disposed over the discharge aperture.

主权项

1. A method comprising:
flowing a conductive fluid within a fluid conduit disposed within a electrosurgical wand, the conductive fluid is discharged through a discharge aperture in the direction of a return electrode, whereupon the return electrode deflects at least a portion of the conductive fluid toward an active electrode; applying electrical energy between the active and return electrodes; forming, responsive to the energy, a plasma proximate to the active electrode; and treating a wound by placing the active electrode adjacent to the wound, and translating the active electrode along the wound.
