METHODS AND SYSTEMS RELATED TO ELECTROSURGICAL WANDS

摘要

Electrosurgical wands. At least some of the illustrative embodiments are electrosurgical wands having features that reduce contact of tissue with an active electrode of a wand, decrease the likelihood of clogging, and/or increase the visibility within surgical field. For example, wands in accordance with at least some embodiments may comprise standoffs, either along the outer perimeter of the active electrode, or through the main aperture in the active electrode, to reduce tissue contact. Wands in accordance with at least some embodiments may implement slots on the active electrodes to increase bubble aspiration to help keep the visual field at the surgical site clear. Wands in accordance with at least some embodiments may implement aspiration flow pathways within the wand that increase in cross-sectional area to reduce the likelihood of clogging.

主权项

1. An electrosurgical wand comprising:
an elongate housing that defines a handle end and a distal end; a spacer of non-conductive material disposed on the distal end; a conductive electrode disposed on the spacer; a pilot electrode disposed adjacent to the conductive electrode, wherein the pilot electrode is located within a recess of the spacer, and wherein the recess is in communication with a channel, the channel defining a fluid pathway in contact with the conductive electrode.
