An arthroscopic surgical instrument comprises a hollow tube having a proximal and a distal end. A stationary jaw is coupled to the distal end of the tube, said stationary jaw having a pair of side walls and a distal end wall defining an opening, said distal end wall having a concave inner surface. A movable jaw is coupled to the actuating means and pivots about an axis of rotation relative to said stationary jaw, wherein said movable jaw pivots in said opening, and said concave inner surface of said distal end wall is defined by a radius from said axis of rotation, with a distal portion of said movable jaw closely engaging said concave inner surface when said movable jaw pivots in said opening. Actuating means are coupled to said proximal end of said tube and coupled to said movable jaw for effecting pivoting of said movable jaw relative to said stationary jaw. <IMAGE> |
