Fastener cartridge assembly comprising a fixed anvil and different staple heights
A stapling assembly comprising an anvil jaw and a staple cartridge jaw is disclosed. The staple cartridge jaw comprises a row of staple cavities comprising a first staple cavity, a second staple cavity, and a third staple cavity. The staple cartridge jaw further comprises a first staple driver, a second staple driver, a third staple driver, and staples. The staples comprise a first staple positioned in the first staple cavity, a second staple positioned in the second staple cavity, and a third staple positioned in the third staple cavity. The first staple driver is lifted to a first fired height by the first staple driver. The second staple driver is lifted to a second fired height by the second staple driver. The third staple driver is lifted to a third fired height by the third staple driver.
1. A stapling assembly, comprising:
an anvil comprising a longitudinal row of staple forming pockets; and
a staple cartridge, comprising:
a proximal end;
a distal end;
a longitudinal slot extending from said proximal end toward said distal end;
a longitudinal row of staple cavities, comprising:
a first group of staple cavities;
a second group of staple cavities positioned distal with respect to said first group of staple cavities; and
a third group of staple cavities positioned distal with respect to said second group of staple cavities;
staple drivers; and
staples, comprising:
a first group of staples positioned in said first group of staple cavities, wherein said first group of staples are deformed against said staple forming pockets to a first formed height by said staple drivers during a staple firing stroke;
a second group of staples positioned in said second group of staple cavities, wherein said second group of staples are deformed against said staple forming pockets to a second formed height by said staple drivers during said staple firing stroke, wherein said second formed height is different than said first formed height; and
a third group of staples positioned in said third group of staple cavities, wherein said third group of staples are deformed against said staple forming pockets to a third formed height by said staple drivers during said staple firing stroke, and wherein said third formed height is different than said second formed height and said first formed height.
2. The stapling assembly of claim 1 , wherein said second formed height is taller than said first formed height, and wherein said third formed height is taller than said second formed height.
3. The stapling assembly of claim 1 , wherein said second formed height is shorter than said first formed height, and wherein said third formed height is shorter than said second formed height.
4. A stapling assembly, comprising:
an anvil jaw; and
a staple cartridge jaw, comprising:
a row of staple cavities, comprising:
a first staple cavity;
a second staple cavity; and
a third staple cavity;
a first staple driver;
a second staple driver;
a third staple driver; and
staples, comprising:
a first staple positioned in said first staple cavity, wherein said first staple driver is lifted to a first fired height by said first staple driver during a staple firing stroke to deform said first staple to a first formed height;
a second staple positioned in said second staple cavity, wherein said second staple driver is lifted to a second fired height by said second staple driver during a staple firing stroke to deform said second staple to a second formed height, wherein said second formed height is different than said first formed height; and
a third staple positioned in said third staple cavity, wherein said third staple driver is lifted to a third fired height by said third staple driver during a staple firing stroke to deform said third staple to a third formed height, and wherein said third formed height is different than said second formed height and said first formed height.
5. The stapling assembly of claim 4 , wherein said second formed height is taller than said first formed height, and wherein said third formed height is taller than said second formed height.
6. The stapling assembly of claim 4 , wherein said second formed height is shorter than said first formed height, and wherein said third formed height is shorter than said second formed height.
