Abstract
A surgical cutting instrument having an outer tubular member with a closed distal end, and an aperture therein which is adjacent to the closed distal end and which is in communication with the hollow of the outer tubular member. The instrument also includes an inner tube slidably disposed in the outer tube such that it reciprocates between first and second positions. The instrument also has a suction device which draws a portion of an object inwardly through the aperture. The inner tubular member has first and second edges which cooperate with the aperture such that when the suction device draws a first portion of the object into the aperture, the first edge cuts this portion away as the inner tubular member moves from the first position to the second position. However, when the suction device draws a second portion of the object into the aperture, the second edge cuts this portion away as the inner tubular member moves from the first position to the second position.
