ABSTRACT:
A surgical cutting instrument comprising an outer tube having a peripheral wall, an end wall and an opening in the peripheral wall and the end wall. The outer tube has first and second cutting edges defining portions of the periphery of the opening, and the cutting edges intersect at an angle of at least about 90 degrees to define a corner. An inner cutting member is rotatable within the outer tube. The inner cutting member has a cutting edge cooperable with both the first and second cutting edges of the outer tube for cutting material with a shearing action that progresses along both of the first and second cutting edges toward the corner.
