Abstract

A surgical staple and staple cartridge for removably storing the surgical staple. The surgical staple can comprise staple legs positioned in a staple leg plane and a staple base. An intermediate portion of the staple base can be laterally offset from the staple leg plane, and/or the center of mass of the staple can be laterally offset from the staple leg plane. The surgical staple can be formed and/or stamped from a sheet of material.

Claims

1. A surgical staple, comprising:

a base comprising an intermediate portion;

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;

wherein the intermediate portion of the base extends parallel to the plane, and wherein the intermediate portion of the base is laterally offset from the plane.

2. The surgical staple of claim 1, wherein a gusset extends between the first staple leg and the base.

3. The surgical staple of claim 1, further comprising a first discrete drive surface laterally aligned with the plane and a second discrete drive surface laterally offset from the plane.

4. The surgical staple of claim 3, wherein the first discrete drive surface and the second discrete drive surface are integrally formed in the base.

5. The surgical staple of claim 1, wherein the first leg extends from a proximal portion of the base, and wherein the second leg extends from a distal portion of the base.

6. A surgical staple, comprising:

a base;

a pair of staple legs defining a leg plane; and

a center of mass offset from the leg plane.

7. The surgical staple of claim 6, wherein a longitudinal axis extends between the staple legs, and wherein the base is asymmetrical relative to the longitudinal axis.

8. The surgical staple of claim 6, wherein the base further comprises a first discrete drive surface that is aligned with the leg plane.

9. The surgical staple of claim 8, wherein the base further comprises a second discrete drive surface that is laterally offset from the leg plane.

10. The surgical staple of claim 9, wherein the first discrete drive surface and the second discrete drive surface are integrally formed in the base.

11. The surgical staple of claim 6, wherein the base further comprises a drive surface comprising an inclined surface.

12. The surgical staple of claim 6, wherein the base further comprises a drive surface comprising a nub.

13. The surgical staple of claim 6, wherein a gusset extends between a first staple leg and the base.

14. The surgical staple of claim 6, wherein the base further defines a contour.

15. A staple cartridge, comprising:

a cartridge body;

a staple cavity defined in the cartridge body, wherein the staple cavity comprises a longitudinal sidewall; and

a staple comprising a metallic base, wherein the base comprises a longitudinal guide surface moveably positioned adjacent to the longitudinal sidewall of the staple cavity.

16. The staple cartridge of claim 15, wherein the staple comprises:

a first staple leg;

a second staple leg, wherein the first staple leg and the second staple leg define a leg plane; and

a center of mass positioned outside the leg plane.

17. The staple cartridge of claim 16, wherein the base comprises a drive surface that is laterally offset from the leg plane.

18. The staple cartridge of claim 15, wherein the staple cavity further comprises:

a proximal end configured to guide a first staple leg; and

a distal end configured to guide a second staple leg, wherein the longitudinal sidewall is intermediate the proximal end and the distal end.

19. The staple cartridge of claim 15, wherein a longitudinally-driven sled directly lifts the longitudinal guide surface of the staple along the longitudinal sidewall of the staple cavity.

20. The staple cartridge of claim 15, wherein the staple is asymmetrical relative to a longitudinal axis of the staple.

21. A surgical staple, consisting of:

a base;

a first staple leg;

a second staple leg, wherein the first staple leg and the second staple leg define a leg plane; and

a center of mass offset from the leg plane.

22. A surgical staple stamped from a sheet of material, the surgical staple comprising:

a first leg;

a second leg, wherein the first leg and the second leg define a leg plane; and

a base contiguously connecting the first leg and the second leg, wherein the base is bent out of the leg plane.
