Claim 8:
9. A surgical instrument, comprising:
an end effector, wherein the end effector includes:
(i) an upper jaw the upper jaw including a proximal end and a distal end;
(ii) a lower jaw, the lower jaw including a proximal end and a distal end, wherein the distal end of the upper jaw is connected to the distal end of the lower jaw, and wherein the proximal end of the upper jaw is connected to the proximal end of the lower jaw;
(iii) a knife assembly comprising a knife, a beam, and a firing nut, wherein the beam is coupled to the firing nut, wherein the firing nut has a proximal side and a distal side;
(iv) a firing lead screw having a distal end and a proximal end, wherein rotation of the firing lead screw in a first direction proximally drives the firing nut along the firing lead screw and rotation of the firing lead screw in a second direction distally drives the firing nut along the firing lead screw; and
(v) a firing screw compression spring extending along the firing lead screw, wherein the firing screw compression spring is positioned between the firing nut and the distal end of the firing lead screw, wherein rotation of the firing lead screw in a first direction proximally translates the compression spring along the firing lead screw and rotation of the firing lead screw in a second direction distally translates the compression spring along the firing lead screw.
