an elongate shaft assembly including a tube having a lip extending radially inward; and
a jaw being axially movable relative to the tube to clamp an arcuate suture needle between the tube and the jaw, the jaw including a recessed portion including:
a first arcuate surface;
a first planar surface proximal of the first arcuate surface;
a second arcuate surface proximal of the first planar surface; and
a second planar surface proximal of the second arcuate surface,

wherein the first arcuate surface has a first radius of curvature and the second arcuate surface has a second radius of curvature different from the first radius of curvature and the lip of the tube defines a recess having a radius of curvature identical to the second radius of curvature of the second arcuate surface of the recessed portion of the jaw.
