Abstract

A surgical staple cartridge is disclosed comprising a plurality of staples removably stored within the surgical staple cartridge. The staples comprise staple legs which extend from a staple base portion. The staple legs comprise staple tips configured to pierce tissue and contact a corresponding forming pocket of an anvil of surgical stapling instrument. The staples further comprise zones having different hardnesses.

Claims (45)

1. A surgical end effector assembly, comprising:

a first jaw;

a second jaw movable relative to said first jaw; and

a replaceable staple cartridge, comprising:

a sled;

a cartridge body, comprising:

a deck; and

a plurality of staple cavities defined in said deck;

a plurality of stamped staples removably stored within said staple cavities, wherein each said stamped staple comprises:

a first leg;

a second leg; and

a flat connector portion connecting said first leg and said second leg, wherein said flat connector portion is laterally offset with respect to said first leg and said second leg, wherein said first leg and said second leg extend laterally from said flat connector portion in a first direction, and wherein said flat connector portion is engaged by said sled during a staple firing stroke; and

a connector strip interconnecting said plurality of stamped staples, wherein each said stamped staple extends laterally from said connector strip in a second direction laterally opposite said first direction.

2. The surgical end effector assembly of claim 1 , wherein said plurality of stamped staples are arranged in a first longitudinal row of staples and a second longitudinal row of staples, wherein said staples of said first longitudinal row of staples comprise a first unformed height and said staples of said second longitudinal row of staples comprise a second unformed height, and wherein said first unformed height and said second unformed height are different.

3. The surgical end effector assembly of claim 1 , wherein said connector strip is attached to a bottom surface of each said flat connector portion of each said stamped staple.

4. The surgical end effector assembly of claim 1 , wherein said flat connector portion connects said staple legs of a first said stamped staple and said staple legs of a second said stamped staple.

5. A surgical end effector assembly, comprising:

a first jaw;

a second jaw movable relative to said first jaw; and

a replaceable staple cartridge, comprising:

a sled;

a cartridge body, comprising:

a deck; and

a plurality of staple cavities defined in said deck;

a plurality of stamped staples removably stored within said staple cavities, wherein each said stamped staple comprises:

a flat connector portion configured to be engaged by said sled to eject each said staple from said plurality of staple cavities; and

staple legs extending upwardly from said flat connector portion in a first lateral direction, wherein said flat connector portion is laterally offset with respect to said staple legs; and

a connector strip interconnecting said plurality of stamped staples, wherein each said stamped staple extends laterally from said connector strip in a second lateral direction opposite said first lateral direction.

6. The surgical end effector assembly of claim 5 , wherein said plurality of stamped staples are arranged in a first longitudinal row of staples and a second longitudinal row of staples, wherein said staples of said first longitudinal row of staples comprise a first unformed height and said staples of said second longitudinal row of staples comprise a second unformed height, and wherein said first unformed height and said second unformed height are different.

7. The surgical end effector assembly of claim 5 , wherein said connector strip is attached to a bottom surface of each said flat connector portion of each said stamped staple.

8. The surgical end effector assembly of claim 5 , wherein said replaceable staple cartridge further comprises at least one connector strip connecting said staple legs of at least one said stamped staple.

9. The surgical end effector assembly of claim 8 , wherein said at least one connector strip is positioned adjacent a top surface of said flat connector portion.

10. The surgical end effector assembly of claim 5 , wherein said replaceable staple cartridge further comprises at least one connector strip connecting said staple legs of more than one said stamped staple.

11. A surgical end effector assembly, comprising:

a first jaw;

a second jaw movable relative to said first jaw; and

a replaceable staple cartridge, comprising:

a sled;

a cartridge body, comprising:

a deck; and

a plurality of staple cavities defined in said deck;

a plurality of stamped staples removably stored within said staple cavities, wherein each said stamped staple comprises:

a flat connector portion; and

staple legs extending upwardly and in a first lateral direction from said flat connector portion, wherein said staple legs are laterally offset with respect to said flat connector portion, and wherein said flat connector portion is engaged by said sled during a staple firing stroke; and

a connector strip connecting at least two of said stamped staples, wherein each said stamped staple extends laterally from said connector strip in a second lateral direction opposite said first lateral direction.
