Abstract
Remote-cutting instrument formed by an inner tube rotating within an outer tube, in which an initial cutting point where portions of the tubes first come together during a cutting cycle is defined at the distal extremity of the sides of the tubes and cutting edges extend from this initial point longitudinally along the sides of the tubes. The coacting side edges of the tubes diverge in the proximal direction. There are end cutting edges of circular form, defining cusp-shaped points.
