Abstract
An electrosurgical instrument for spinal procedures comprises an elongated tubular member configured to fit within and be extended down a standard sized cannula. The instrument comprises a proximal end including a handle for the surgeon and supplied with fittings for connection to a source of irrigation fluid and a source of suction. The distal end of the instrument has an active end comprising a slightly-flexible curved wire electrode that extends in the plane of the tubular member. Beyond the wire electrode is an exit port for irrigation fluid, and in front of the electrode is a receiving port for suction. The wire electrode is thus flanked in front by the exiting irrigation fluid and behind by the suction, with the result that fluid flow is drawn by the suction across the wire electrode creating pressure forces that direct removed tissue to the suction entrance and its removal from the surgical site.
