ELECTROSURGERY WITH INFILTRATION ANESTHESIA

摘要

Method for carrying out the recovery of an intact volume of tissue wherein a delivery cannula tip (22) is positioned in confronting adjacency with the volume of tissue to be recovered. The electrosurgical generator employed to form an arc at a capture component extending from the tip is configured havi ng resistance-power profile which permits recovery of the specimen without excessive thermal artifact while providing sufficient power to sustain a cutting arc. For the recovery procedure, a local anesthetic employing a diluent which exhibits a higher resistivity is utilized and the method for deploying the capture component (200) actuation interspersed with pauses of duration effective to evacuate any accumulation or pockets of local anesthet ic solution encountered by the cutting electrodes.
