Claim:
1. A surgical instrument comprising: a rod having a length with opposite proximal and distal ends and a center axis that extends along the rod length and defines mutually perpendicular axial and radial directions relative to the surgical instrument; a ring mounted on the rod for axially reciprocating movement between first and second positions of the ring along the rod length, the ring being movable toward the rod proximal end to the first position of the ring on the rod and the ring being movable toward the rod distal end to the second position of the ring on the rod, a sliding surface on the ring, the sliding surface facing axially toward the rod proximal end; a handle on the rod, the handle having a plurality of arms, the plurality of arms having interior surfaces that are circumferentially spaced around the rod and exterior surfaces that are on radially opposite sides of the interior surfaces with there being axially extending slots between the interior and exterior surfaces of adjacent arms of the plurality of arms, the plurality of arms extending axially from the rod proximal end along the rod to free distal ends of the arms, the plurality of arms having surfaces on the free distal ends of the arms that are positioned in a same radial plane as the sliding surface on the ring and radially outwardly and surrounding the sliding surface on the ring and face axially toward the ring sliding surface, and the surfaces on the free distal ends of the arms having rounded shapes that extend as continuous surfaces from the interior surfaces of the arms around the distal ends of the arms to the exterior surfaces of the arms.
