Abstract

An exemplary surgical staple may include a base including a first end and a second end; a single tine extending from the second end of the base; and a barb extending from the base at a location between the first end of the base and the second end of the base. An end of such a staple may be frangibly affixed to a feeder belt. Another exemplary surgical apparatus may include at least one staple including a base including a first end and a second end, a first tine extending from the second end of the base, and a second tine extending from the base at a location between the first end of the base and the second end of the base.

Claims

1. A surgical stapling apparatus, comprising:

a staple holder configured to hold staples;

a plurality of staples contained within said staple holder, wherein one of the plurality of staples comprising;

a base including a first end and a second end, wherein said first end configured to frangibly detach from an attachment contained within said staple holder; and

two tines extending from said base, wherein a first tine extends from said second end of said base and wherein a second tine extends from a location between said first tine and said first end of said base; and

an anvil configured to deform said plurality of staples as said plurality of staples are deployed wherein said first tine and said second tine are positioned or oriented laterally offset relative to one another.

2. The surgical stapling apparatus of claim 1, wherein said first tine and said second tine are substantially of equal lengths.

3. The surgical stapling apparatus of claim 1, wherein said anvil includes at least one staple forming pocket.

4. The surgical stapling apparatus of claim 3, wherein at least one said staple forming pocket includes two sub-pockets.

5. The surgical stapling apparatus of claim 4, wherein said two sub-pockets being positioned or oriented laterally offset relative to one another.

6. The surgical stapling apparatus of claim 4, wherein said sub-pockets configured to cause both said first tine and said second tine to deform or close upon contact between said staple and a corresponding staple forming pocket of said anvil.

7. The surgical stapling apparatus of claim 1, wherein said attachment being coupled or connected to said staple holder.

8. The surgical stapling apparatus of claim 1, wherein said attachment being coupled to or connected to a staple feeder belt contained at least partially within said staple holder.

9. A surgical stapling apparatus, comprising:

a staple holder configured to hold staples;

a plurality of staples contained within said staple holder, wherein one of the plurality of staples comprising;

a base including a first end and a second end, wherein said first end configured to frangibly detach from an attachment contained within said staple holder;

a tine extending from said second end of said base and a barb extending from a location between said tine and said first end of said base; and

an anvil configured to deform said plurality of staples as said plurality of staples are deployed.

10. The surgical stapling apparatus of claim 9, wherein said tine and said barb are substantially of unequal lengths.

11. The surgical stapling apparatus of claim 9, wherein said tine and said barb are positioned or oriented laterally offset relative to one another.

12. The surgical stapling apparatus of claim 9, wherein said anvil includes at least one staple forming pocket.

13. The surgical stapling apparatus of claim 12, wherein at least one said staple forming pocket includes two sub-pockets.

14. The surgical stapling apparatus of claim 13, wherein said two sub-pockets being positioned or oriented laterally offset relative to one another.

15. The surgical stapling apparatus of claim 13, wherein said sub-pockets configured to cause both said tine and said barb to deform or close upon contact between said staple and a corresponding staple forming pocket of said anvil.

16. The surgical stapling apparatus of claim 9, wherein said attachment coupled or connected to said staple holder.

17. The surgical stapling apparatus of claim 9, wherein said attachment coupled to or connected to a staple feeder belt contained at least partially within said staple holder.
