Abstract
A tubular microsurgery cutting apparatus is disclosed having an outer tubular member and an inner tubular sleeve reciprocatable within the outer tubular member. The inner tubular sleeve is formed near its cutting end with an enlarged diameter, plated and lapped area having a spiral axial slot extending away from the cutting end along the sleeve. This construction provides for a smooth, friction reducing engagement between the sleeve and the inside of the outer tubular member at the cutting end and a substantially non-frictional relationship of the inner sleeve and outer member throughout the remainder of the apparatus.
