Summary:An electrosurgical device including the disclosure describes an electrosurgical device including an elongated body having a tubular section extending from a proximal end to a distal end and defining an evacuation channel configured to evacuate tissue from the distal end to the proximal end, a curette at the distal end of the tubular section, wherein the curette defines a perimeter cutting edge that forms a distal opening to the evacuation channel, a plasma cutting electrode defined by the perimeter cutting edge of the curette, where the plasma cutting electrode is configured to operate in a monopolar configuration to deliver radio frequency (RF) plasma energy to adjacent tissue to cut a volume of the target tissue, and a dielectric coating on at least a portion of the curette, the dielectric coating electrically insulating the curette from target tissue and the volume of cut target tissue, wherein the dielectric coating comprises a ceramic material.
