Abstract

A surgical staple, comprising a backspan, a first leg member extending from the backspan, a second leg member extending from the backspan, and at least one substantially continuous channel extending along at least one of an inner surface and an outer surface of the first leg member and the second leg member.

Claims

1. A surgical staple, comprising:

a backspan;

a first leg member extending from the backspan;

a second leg member extending from the backspan; and

at least one substantially continuous channel extending along at least one of an inner surface and an outer surface of the first leg member and the second leg member.

2. The surgical staple of claim 1, wherein the at least one substantially continuous channel is semi-circular.

3. The surgical staple of claim 1, wherein the surgical staple is formed from a material selected from the group consisting of titanium and stainless steel.

4. The surgical staple of claim 1, wherein the at least one substantially continuous channel extends along the inner surface of the first and second leg members and backspan of the surgical staple.

5. The surgical staple of claim 1, wherein the at least one substantially continuous channel extends along the outer surface of the first and second leg members and backspan of the surgical staple.

6. The surgical staple of claim 1, wherein a transverse cross-section of each leg member includes a length and a height, the height defined by the distance between the wall having the channel and an opposing wall, and the length being greater than the height.

7. The surgical staple of claim 1, wherein each leg member includes a substantially uniform transverse cross-section along its length.

8. The surgical staple of claim 1, wherein a width of the at least one substantially continuous channel is between about 0.004 inches and about 0.007 inches.

9. The surgical staple of claim 1, wherein a depth of the at least one substantially continuous channel is between about 0.001 inches and about 0.004 inches.

10. The surgical staple of claim 1, wherein the legs are configured to come into contact with the anvil pockets for bending of the staple legs to form the staple.

11. A staple cartridge for use with a surgical stapler, the staple cartridge comprising:

a plurality of surgical staples in a spaced relation to each other, each of the surgical staples including;

a backspan;

a pair of deformable legs extending from the backspan, the legs configured to come into contact with the anvil pockets for formation of the staple; and

at least one substantially continuous channel extending along at least one of an inner surface and an outer surface of the deformable legs.

12. The staple cartridge of claim 11, wherein the at least one substantially continuous channel is semi-circular.

13. The surgical staple of claim 11, wherein the at least one substantially continuous channel extends along the inner surface of the first and second leg members and backspan of the surgical staple.

14. The surgical staple of claim 11, wherein the at least one substantially continuous channel extends along the outer surface of the first and second leg members and backspan of the surgical staple.

15. The staple cartridge of claim 11, wherein a transverse cross-section of each leg member includes a length and a height, the height defined by the distance between the wall having the channel and an opposing wall, and the length being greater than the height.

16. A directionally biased surgical staple, comprising:

a backspan;

a first leg member extending from the backspan;

a second leg member extending from the backspan; and

at least one substantially continuous channel extending along a surface of the backspan, the first leg member and the second leg member.

wherein a transverse cross-section of each leg member includes a length and a height, the height defined by the distance between the wall having the channel and an opposing wall, and the length being greater than the height.

17. The staple of claim 16, further comprising a second substantially continuous channel entering along a surface of the backspan, the first leg member and the second leg member.
