Summary:Rongeur and method for removing intervertebral disk tissue from a spinal column of a patient. A pair of bipolar electrodes on an elongated shaft is placed in proximity to the intervertebral disk tissue. Without withdrawing the instrument from the spinal column, the electrodes are activated with a source of RF energy to stiffen the intervertebral disk tissue, a source of saline solution is supplied to the intervertebral disk tissue and the intervertebral disk tissue is grasped with a grasping tool affixed in conjunction with the distal portion of the elongated shaft biting off a portion of the intervertebral disk tissue having been stiffened. The instrument is withdrawn from the spinal column of the patient to remove the portion of the intervertebral disk tissue. The inserting step, the placing, activating, supplying, grasping, and withdrawing steps are repeated until a desired portion of the intervertebral disk tissue has been removed.
