Claim 23:
24. A surgical instrument to staple and resect an anatomical structure of a patient, the surgical instrument comprising:
(a) an end effector, the end effector comprising;
(i) a first jaw having a first end, a second end, an anvil having an anvil face, and a first channel; the anvil further comprising a plurality of pocket rows, each pocket row comprising a plurality of staple pockets, wherein the plurality of pocket rows includes at least one pocket row whose plurality of staple pockets comprises a depth that differs from the depth of the plurality of staple pockets of at least one other pocket row;
(ii) a second jaw having a first end, a second end, a cartridge having a cartridge face, and a second channel;
(iii) a first coupling that couples the first end of the first jaw to the first end of the second jaw;
(iv) a second coupling including a one-piece rigid link, the one-piece rigid link being inflexible and having a first end and a second end, wherein, when the end effector is in both a first open position and a second closed position, the first end of the one-piece rigid link is movably and fixedly connected to the first jaw, wherein the one-piece rigid link includes a first portion offset and angled from a second portion, the one-piece rigid link further including a ramp surface; and
(v) an I-shaped blade, the I-shaped blade comprising a blade portion having a cutting edge, at least one upper lateral arm, wherein the at least one upper lateral arm is slidably positioned in the first channel, and at least one lower lateral arm, wherein the at least one lower lateral arm is slidably positioned in the second channel; and

(b) an elongate tube, the elongate tube having a proximal end and a distal end, wherein the distal end is coupled with the end effector and wherein the second end of the rigid link is movably and fixedly connected to the elongate tube;
(c) a handle, the handle having a proximal end and a distal end, wherein the distal end of the handle is coupled with the proximal end of the elongate tube; and
(d) a drive assembly comprising a motor to actuate the end effector,
wherein the end effector has a distal end and a proximal end, and a distance between the distal end and the proximal end is fixed; and
wherein a staple configuration in which a staple of the plurality of staples is formed is based on the depth of a corresponding staple pocket.
