主权项 1. A surgical stapler comprising: a shaft portion; a tool assembly supported on a distal end of the shaft portion, the tool assembly including an anvil and a cartridge assembly, the cartridge assembly including a cartridge body having at least one leg defining a plurality of notches, and a plurality of staples, each of the staples having an intermediate portion interconnecting first and second staple legs wherein the intermediate portion of each of the staples has a first end connected to the first leg and a second end connected to the second leg, wherein the first and second ends of the intermediate portion are axially offset from each other; and at least one firing cam including a distal end defining a cam member having first and second cam surfaces, the first and second cam surfaces being axially offset from each other, the cam member being movable within the tool assembly to move the first and second cam surfaces into sequential engagement with the first and second staple legs, respectively, of each of the plurality of staples, wherein engagement between the cam member and the first and second staple legs of each of the plurality of staples effects rotational movement of each of the plurality of staples to fire each of the plurality of staples from the cartridge body.
