Abstract
An electrosurgical device comprising an elongate probe member having proximal and distal extremities and a passage extending from the proximal extremity to an opening at the distal extremity. The elongate probe member is provided with an elongate cutout adjacent the opening so that the elongate probe member is formed with an elongate extension projecting alongside the cutout beyond the opening. A guide canula is mounted in the passage of the elongate probe member and has proximal and distal extremities and a lumen extending therethrough. A radio frequency electrode is disposed in the lumen and an insulating sleeve is coaxially disposed on the radio frequency electrode. A handle is secured to the proximal extremity of the guide canula for advancing and retracting the radio frequency electrode and the insulating sleeve with respect to the guide canula and for causing bending of the distal extremity of the guide cannula into the cutout. The extension of the elongate probe member provides support to the guide cannula against the force of the radio frequency electrode engaging the tissue. A method for using the device is provided.
