Abstract

A surgical fastening system can comprise a plurality of fasteners, wherein each fastener can comprise, one, a base and, two, a leg extending from the base, wherein each leg can comprise a tip. The fastener system can further comprise a retention matrix comprising a first side facing toward the bases of the fasteners, a second side facing away from the bases of the fasteners, and a plurality of retention members configured to engage the legs. The fastener system can further comprise a cover configured to cover the staple tips, wherein the cover can comprise a sheet of material and/or a plurality of caps.

Claims

1. A surgical stapling system, comprising:

a first staple, comprising;

a first base; and

a first leg extending from said first base, the first leg comprising a first tip;

a second staple, comprising;

a second base; and

a second leg extending from said second base, the second leg comprising a second tip; and

a retention matrix, comprising;

a first layer, comprising;

a first side facing toward said first base and said second base;

a second side facing away from said first base and said second base;

a first retention member configured to engage said first leg;

a second retention member configured to engage said second leg; and

a cover extending along said second side of said first layer, wherein said cover is configured to receive said first tip and said second tip.

2. The surgical stapling system of claim 1, wherein said cover comprises a top surface, a bottom surface, and a thickness defined between said top surface and said bottom surface, wherein said bottom surface is penetrable by said first tip and said second tip, and wherein said thickness is configured such that said first tip and said second tip do not extend through said top surface when said retention matrix is engaged with said first staple and said second staple.

3. The surgical stapling system of claim 1, wherein said cover comprises a second layer penetrable by said first tip and said second tip and a third layer impenetrable by said first tip and said second tip.

4. The surgical stapling system of claim 3, wherein said second layer is adhered to said first layer, and wherein said third layer is adhered to said second layer.

5. The surgical stapling system of claim 3, wherein said first layer is comprised of metal, and wherein said second layer is more flexible than said first layer.

6. The surgical stapling system of claim 1, wherein said cover comprises a second layer penetrable by said first tip and said second tip and a third layer comprises a toughness which is greater than said second layer.

7. A surgical stapling system, comprising:

a plurality of staples, each staple comprising a base, and a leg extending from said base, wherein each said leg comprises a tip; and

a retention matrix, comprising;

a first side facing toward said bases of said staples;

a second side facing away from said bases of said staples;

a plurality of retention members configured to engage said legs; and

a plurality of caps configured to cover said tips.

8. The surgical stapling system of claim 7, wherein each said cap comprises means for engaging a said staple leg.

9. The surgical stapling system of claim 7, wherein each said cap comprises an anvil surface configured to deform a said tip of a said staple leg.

10. The surgical stapling system of claim 9, wherein said anvil surface comprises a dome.

11. The surgical stapling system of claim 7, wherein each said cap comprises a retention lip surrounding said anvil surface.

12. The surgical stapling system of claim 7, wherein each said cap comprises a retention aperture defined by an aperture width, wherein each said leg is defined by a leg width, and wherein said leg width is wider than said aperture width.

13. The surgical stapling system of claim 12, wherein said caps are comprised of a flexible material.

14. The surgical stapling system of claim 7, wherein said caps are unconnected to one another.

15. The surgical stapling system of claim 7, wherein at least some of said caps are connected to one another.

16. The surgical stapling system of claim 7, further comprising a first cartridge containing said plurality of staples and a second cartridge comprising said plurality of caps.

17. The surgical stapling instrument of claim 7, further comprising a flexible sheet, wherein said caps are embedded within said sheet.

18. The surgical stapling instrument of claim 17, wherein said flexible sheet is comprised of silicone and said caps are comprised of metal.

19. A surgical stapling system, comprising:

a plurality of staples, each staple comprising a base, and a leg extending from said base, wherein each said leg comprises a tip; and

a retention matrix, comprising;

a first side facing toward said bases of said staples;

a second side facing away from said bases of said staples;

a plurality of retention members configured to engage said legs; and

covering means for covering said tips.
