摘要：
A surgical instrument including a system for stopping a beam of the surgical instrument from impacting a distal pin when reversing a knife is disclosed. A knife assembly of the surgical instrument comprises the knife, the beam, and a firing nut. A firing lead screw can drive the firing nut distally and proximally. A firing screw compression spring extends along the firing lead screw and applies a load proximally on the firing nut when the firing nut is driven toward a distal end of the firing lead screw.
