ABSTRACT:
A resectoscope used in performing transurethral operations has a telescope extending longitudinally of the instrument which is supported and stabilized by an elongated metallic tube which at its proximate end is fixed to the block of the electrotome. In accordance with the invention the distal end of the tube is extended beyond the distal end of the telescope sufficiently that there will be no interference with illumination through the telescope and the distal end of the tube is coated for a substantial distance from its extreme distal end with a material which is nonconductive to electricity, resistant to high temperatures and chemicals used in transurethral procedures, and provides an antifriction surface on a surface to which it adheres.
