Abstract

A staple cartridge comprising a cartridge body is disclosed. The cartridge body may comprise a deck and a plurality of staple cavities. The cartridge body further comprises a plurality of staples removably positioned within the staple cavities, wherein each staple is movable between an unfired position and a fired position. Each staple comprises a base, a first leg extending from the base, and a second leg extending from the base, wherein the first leg and the second leg define a plane. The base comprises an offset portion which is offset with respect to the plane when the staple is in the unfired position.

Claims

1. A staple cartridge, comprising:

a cartridge body, comprising;

a deck; and

a plurality of staple cavities, wherein each said staple cavity comprises an opening in said deck; and

a plurality of staples removably positioned within said staple cavities, wherein each said staple is movable between an unfired, unformed position and a fired, formed position, and wherein each said staple comprises;

a base;

a first leg extending from said base; and

a second leg extending from said base, wherein said first leg and said second leg define a plane, wherein said base comprises a lateral portion which extends laterally with respect to said plane when said staple is in said unfired, unformed position.

2. The staple cartridge of claim 1, wherein said first leg comprises a first diameter, and wherein said lateral portion of said base comprises a lateral width which is wider than said first diameter.

3. The staple cartridge of claim 2, wherein said second leg comprises a second diameter, and wherein said lateral width is wider than said second diameter.

4. The staple cartridge of claim 1, wherein said base, said first leg, and said second leg comprise a continuous member.

5. The staple cartridge of claim 1, wherein each said staple cavity comprises:

a first portion configured to receive a said first leg of a said staple;

a second portion configured to receive a said second leg of a said staple; and

a lateral portion configured to closely receive a said lateral portion of a said base.

6. The staple cartridge of claim 1, further comprising a sled configured to directly engage said staples to move said staples between said unfired, unformed position and said fired, formed position.

7. The staple cartridge of claim 6, wherein at least a portion of each said staple is comprised of metal.

8. The staple cartridge of claim 1, further comprising a sled configured to directly engage said staples to move said staples between said unfired, unformed position and said fired, formed position.

9. The staple cartridge of claim 8, wherein at least a portion of each said staple is comprised of metal.

10. A staple cartridge, comprising:

a cartridge body, comprising;

a deck; and

a plurality of staple cavities; and

a plurality of staples removably positioned within said staple cavities, wherein each said staple is movable between an unfired position and a fired position, and wherein each said staple comprises;

a base;

a first leg extending from said base; and

a second leg extending from said base, wherein said first leg and said second leg define a plane, wherein said base comprises an offset portion which is offset with respect to said plane when said staple is in said unfired position.

11. The staple cartridge of claim 10, wherein said first leg comprises a first diameter, and wherein said offset portion is wider than said first diameter.

12. The staple cartridge of claim 11, wherein said second leg comprises a second diameter, and wherein said offset portion is wider than said second diameter.

13. The staple cartridge of claim 10, wherein said base, said first leg, and said second leg comprise a continuous member.

14. The staple cartridge of claim 10, wherein each said staple cavity comprises:

a first portion configured to receive a said first leg of a said staple;

a second portion configured to receive a said second leg of a said staple; and

a offset portion configured to closely receive a said offset portion of a said base.
