1. An electrosurgical wand comprising:

  • an elongate housing that defines a handle end and a distal end;

    a tubing member coupled to the elongate housing;

    a spacer of non-conductive material disposed on the distal end, the spacer defining an end surface and an outer surface;

    a conductive electrode with a primary aperture extending through the conductive electrode and disposed on the spacer end surface, the conductive electrode defining an electrode outer perimeter;

    a spacer aperture extending through a thickness of the spacer up to the primary aperture, the spacer aperture fluidly coupled to the tubing member; and

    a first flow channel defined within the spacer, fluidly connected with the tubing member and terminating with a first flow channel aperture disposed on the spacer outer surface and abutting the electrode outer perimeter, configured to draw liquids and gases around the electrode outer perimeter and through the first flow channel aperture so as to aid visibility of the conductive electrode.
