Abstract: A resectoscope includes a fixed electrode adapted to connect to a first electrical potential, a movable electrode adapted to connect to a second electrical potential and biased transversely towards the fixed electrode, and a spacer coupled to the movable electrode. The movable electrode and the spacer are longitudinally movable relative to the fixed electrode between a first position, wherein the spacer is disposed between the fixed electrode and the movable electrode so as to maintain a spacing between the movable electrode and the fixed electrode against the bias of the movable electrode, and a second position, wherein the spacer is disposed distally of the fixed electrode, allowing the movable electrode to move transversely towards the fixed electrode under the bias of the movable electrode.
