Staple cartridge comprising lubricated staples
A staple cartridge comprising staples that are lubricated before they are loaded into the staple cartridge and after they have been loaded into the staple cartridge is disclosed.
1. A staple cartridge, comprising:
a cartridge body, comprising:
a proximal end;
a distal end;
a deck configured to support patient tissue;
a bottom portion positioned opposite said deck; and
staple cavities defined in said deck;
staples removably stored in said staple cavities, wherein said staples are comprised of a degradable metal;
drivers movable within said staple cavities to drive said staples out of said staple cavities during a staple firing stroke;
a first lubricant coating said staples; and
a second lubricant coating at least a portion of said staples and at least a portion of said deck such that said staples are retained within said staple cavities by said second lubricant, wherein the second lubricant is different than the first lubricant, and wherein said staple cartridge is hermetically sealed within a container.
2. The staple cartridge of claim 1 , wherein said first lubricant comprises sodium stearate.
3. The staple cartridge of claim 2 , wherein said second lubricant comprises a mixture of sodium stearate and LAE.
4. The staple cartridge of claim 1 , wherein said first lubricant comprises LAE.
5. The staple cartridge of claim 4 , wherein said second lubricant comprises sodium stearate.
6. The staple cartridge of claim 1 , wherein said first lubricant comprises a first color and said second lubricant comprises a second color, and wherein said first color and said second color are different.
7. The staple cartridge of claim 1 , wherein said first lubricant comprises a first fluorescent dye and said second lubricant comprises a second fluorescent dye, and wherein said first fluorescent dye and said second fluorescent dye are different colors.
8. The staple cartridge of claim 1 , wherein each said staple cavities comprises a bottom opening defined in said bottom portion and a top opening defined in said deck, wherein said bottom openings are sized and configured to receive said staples in said staple cavities, and wherein said top openings are sized and configured to permit said staples to exit from said staple cavities during said staple firing stroke.
9. The staple cartridge of claim 8 , further comprising a pan attached to said cartridge body, wherein said pan extends under at least a portion of said bottom portion such that said drivers and said staples are prevented from falling out of said staple cavities through said bottom openings.
10. The staple cartridge of claim 1 , further comprising a sled translatable within said cartridge body, wherein said sled is movable distally from an unfired position in said proximal end toward a fired position.
11. The staple cartridge of claim 1 , wherein the degradable metal of said staples is at least partially covered in a coating, and wherein said first lubricant is on said coating.
12. The staple cartridge of claim 11 , wherein said second lubricant is on said coating and first lubricant.
13. The staple cartridge of claim 1 , wherein a first portion of each said staples is covered in a coating and a second portion of each said staple comprises exposed degradable metal that is not covered in a coating, and wherein said first lubricant is on said coating and said exposed degradable metal.
14. The staple cartridge of claim 13 , wherein said second lubricant is on said first lubricant, said coating, and said exposed degradable metal.
15. A staple cartridge, comprising:
a cartridge body, comprising:
a proximal end;
a distal end;
a deck configured to support patient tissue;
a bottom portion positioned opposite said deck; and
staple cavities defined in said deck, wherein each staple cavity comprises staple cavity walls;
staples removably stored in said staple cavities, wherein said staples are comprised of a degradable metal, wherein each said staple comprises a base and legs extending from said base, and wherein said legs of each said staple are engaged with the staple cavity walls of the staple cavity that said staple is positioned in;
a first lubricant applied to said staples intermediate said legs of said staples and said staple cavity walls; and
a second lubricant applied to said staples and positioned within said staple cavities, wherein said second lubricant is not intermediate said legs of said staples and said staple cavity walls when said staples are in an unfired position, and wherein the second lubricant is different than the first lubricant.
16. The staple cartridge of claim 15 , wherein said first lubricant comprises sodium stearate.
17. The staple cartridge of claim 16 , wherein said second lubricant comprises a mixture of sodium stearate and LAE.
18. The staple cartridge of claim 16 , wherein said first lubricant comprises LAE.
19. The staple cartridge of claim 18 , wherein said second lubricant comprises sodium stearate.
20. A staple cartridge, comprising:
a cartridge body, comprising:
a proximal end;
a distal end;
a deck configured to support patient tissue;
a bottom portion positioned opposite said deck; and
staple cavities defined in said deck;
staples removably stored in said staple cavities, wherein said staples are comprised of a degradable metal, wherein each said staple comprises a base and legs extending from said base;
a first lubricant coating each of said base and said legs of said staples; and
a second lubricant covering said legs of said staples but not said base of said staples, wherein the second lubricant is different than the first lubricant, and wherein said staple cartridge is hermetically sealed within a container.
21. The staple cartridge of claim 20 , wherein said first lubricant comprises sodium stearate.
22. The staple cartridge of claim 20 , wherein said second lubricant comprises a mixture of sodium stearate and LAE.
23. The staple cartridge of claim 20 , wherein said first lubricant comprises LAE.
24. The staple cartridge of claim 23 , wherein said second lubricant comprises sodium stearate.
