Abstract

Surgical staples including features which can cooperate with staple cavities in a staple cartridge in order to reduce, or even prevent, the surgical staples from rocking, rotating or tilting, within the staple cavities while the staples are deployed by a staple driver, especially when the staples are oriented at different directions. In various embodiments, the surgical staples can include crowns having arcuate and/or cylindrical features which can cooperate with arcuate and/or cylindrical features of the staple cavities in order to reduce unwanted relative movement, or rotation, between the staples and the staple cavities.

Claims

1. A staple cartridge assembly, comprising:

a staple cartridge body including a cavity, wherein said cavity defines an axis, and wherein said cavity includes a first arcuate portion; and

a staple including a crown, wherein said staple is movable relative to said cavity, wherein said crown includes a first arcuate portion, and wherein said first arcuate portion of said cavity is configured to cooperate with said first arcuate portion of said cavity to guide said staple along said axis.

2. The staple cartridge assembly of claim 1, wherein said first arcuate portion of said crown includes a first partially cylindrical surface, and wherein said first partially cylindrical surface is configured to cooperate with said first arcuate portion of said cavity to guide said staple along said axis.

3. The staple cartridge assembly of claim 1, wherein said cavity further comprises a second arcuate portion, wherein said crown further comprises a second arcuate portion, and wherein said second arcuate portion of said cavity is configured to cooperate with said second arcuate portion of said crown to guide said staple along said axis.

4. The staple cartridge assembly of claim 3, wherein said second arcuate portion of said crown includes a partially cylindrical surface, and wherein said second partially cylindrical surface is configured to cooperate with said second arcuate portion of said cavity to guide said staple along said axis.

5. A staple cartridge assembly, comprising:

a staple cartridge body including a cavity, wherein said cavity defines an axis, and wherein said cavity includes a first arcuate portion; and

a staple including a crown, wherein said staple is movable relative to said cavity, wherein said crown includes a first arcuate portion, and wherein said first arcuate portion of said crown is configured to cooperate with said first arcuate portion of said cavity to inhibit said staple from rotating relative to said axis.

6. The staple cartridge assembly of claim 5, wherein said first arcuate portion of said crown includes a first partially cylindrical surface, and wherein said first partially cylindrical surface is configured to cooperate with said first arcuate portion of said cavity to inhibit said staple from rotating relative to said axis.

7. The staple cartridge assembly of claim 5, wherein said cavity further comprises a second arcuate portion, wherein said crown further comprises a second arcuate portion, and wherein said second arcuate portion of said cavity is configured to cooperate with said second arcuate portion of said crown to inhibit said staple from rotating relative to said axis.

8. The staple cartridge assembly of claim 7, wherein said second arcuate portion of said crown includes a second partially cylindrical surface, and wherein said second partially cylindrical surface is configured to cooperate with said second arcuate portion of said crown to inhibit said staple from rotating relative to said axis.

9. A surgical staple configured to fit within a staple cartridge cavity, wherein said surgical staple is moveable relative to the cavity, wherein the cavity defines an axis, said surgical staple comprising:

a crown, wherein said crown has a first arcuate portion, wherein the cavity has a first arcuate portion, and wherein said first arcuate portion of said crown is configured to cooperate with the first arcuate portion of the cavity to guide said surgical staple along the axis.

10. The surgical staple of claim 9, wherein the first arcuate portion of said crown includes a first partially cylindrical surface, and wherein said first partially cylindrical surface is configured to cooperate with the first arcuate portion of the cavity to guide said surgical staple along said axis.

11. The surgical staple of claim 9, wherein said crown has a second arcuate portion, wherein the cavity has a second arcuate portion, and wherein said second arcuate portion of said crown is configured to cooperate with the second arcuate portion of the cavity to guide said surgical staple along the axis.

12. The surgical staple of claim 11, wherein the second arcuate portion of the crown includes a second partially cylindrical surface, and wherein said second partially cylindrical surface is configured to cooperate with the second arcuate portion of the cavity to guide said surgical staple along said axis.

13. A surgical staple configured to fit within a staple cartridge cavity, wherein said surgical staple is moveable relative to the cavity, wherein the cavity defines an axis, said surgical staple comprising:

a crown, wherein said crown has a first arcuate portion, wherein the cavity has a first arcuate portion, and wherein said first arcuate portion of said crown is configured to cooperate with the first arcuate portion of the cavity to inhibit rotation of said surgical staple relative to said axis.

14. The surgical staple of claim 13, wherein the first arcuate portion of said crown includes a first partially cylindrical surface, and wherein said first partially cylindrical surface is configured to cooperate with the first arcuate portion of the cavity to inhibit rotation of said surgical staple relative to said axis.

15. The surgical staple of claim 13, wherein said crown has a second arcuate portion, wherein the cavity has a second arcuate portion, and wherein said second arcuate portion of said crown is configured to cooperate with the second arcuate portion of the cavity to inhibit rotation of said surgical staple relative to said axis.

16. The surgical staple of claim 15, wherein the second arcuate portion of the crown includes a second partially cylindrical surface, and wherein said second partially cylindrical surface is configured to cooperate with the second arcuate portion of the cavity to inhibit rotation of said surgical staple relative to said axis.
