Abstract

A surgical staple cartridge comprising a first, a second and a third row of staple pockets located on a first side of a cartridge housing having staples therein. The first, the second and the third row of staple pockets are aligned parallel to a knife channel. A first staple driver is oriented to drive at least four staples from the staple pockets simultaneously. A second staple driver configured to eject a staple from the staple pockets and is positioned proximally with respect to the first staple driver. The second staple driver is configured to elect a different quantity of staples than the first staple driver.

Claims

1. A surgical staple cartridge comprising:

a cartridge housing, comprising;

a longitudinal axis;

a proximal end;

a distal end; and

a knife channel disposed along the longitudinal axis dividing the cartridge housing into a first side and a second side;

a first, a second and a third row of staple pockets located on the first side of the cartridge housing having staples therein, wherein the first, the second and the third row of staple pockets are aligned parallel to the knife channel, and wherein at least the second row of staple pockets is offset from the first and the third rows along a transverse axis;

a first staple driver oriented to drive at least four staples from the staple pockets simultaneously, wherein one of the at least four staples is driven from a staple pocket in the first row, wherein one of the at least four staples is driven from a staple pocket in the second row, and wherein two of the at least four staples are driven from a staple pocket in the third row; and

a second staple driver configured to eject a staple from the staple pockets, wherein the second staple driver is positioned proximally with respect to the first staple driver, wherein the second staple driver is configured to be moved independently relative to the first staple driver, and wherein the second staple driver is configured to eject a different quantity of staples than the first staple driver.

2. A staple cartridge comprising:

a cartridge housing, comprising;

a proximal end;

a distal end; and

a knife channel;

an anvil disposed opposite the cartridge housing;

a first, a second and a third row of staple pockets disposed on one side of the knife channel and oriented substantially parallel thereto where the second row is offset from the first and the third rows along an axis transverse to the knife channel;

staples located in the staple pockets;

a first staple driver to drive a staple out of the staple pockets;

a second staple driver to drive at least four staples out of the staple pockets simultaneously, wherein at least two of the at least four staples are in either the first, the second or the third row, wherein the at least four staples contact the anvil simultaneously, and wherein the second staple driver is configured to eject a different quantity of staples than the first staple driver; and

a drive member configured to sequentially drive the first staple driver and the second staple driver toward the anvil.

3. A surgical fastener cartridge, comprising:

a cartridge housing comprising a proximal end and a distal end;

a knife channel defined in the cartridge housing which divides the housing into a first side and a second side;

a first row, a second row, and a third row of fastener pockets located on the first side of the cartridge housing, wherein the first, the second, and the third row of fastener pockets extend alongside the knife channel;

fasteners removably stored in the fastener pockets;

a first fastener driver configured to simultaneously eject a fastener from a fastener pocket in the first row, a fastener from a fastener pocket in the second row, and two fasteners from fastener pockets in the third row; and

a second fastener driver configured to eject a fastener from a fastener pocket, wherein the second fastener driver is positioned proximally with respect to the first fastener driver, wherein the second fastener driver is configured to be moved independently of the first fastener driver, and wherein the second fastener driver is configured to eject a different quantity of fasteners than the first fastener driver.

4. A surgical fastener cartridge, comprising:

a cartridge housing comprising a proximal end and a distal end;

a knife channel defined in the cartridge housing which divides the cartridge housing into a first side and a second side;

a first row, a second row, and a third row of fastener pockets located on the first side of the cartridge housing;

fasteners removably stored in the fastener pockets;

a first fastener driver configured to eject a fastener from a fastener pocket in the first row, a fastener from a fastener pocket in the second row, and two fasteners from fastener pockets in the third row; and

a second fastener driver configured to eject a fastener from a fastener pocket, wherein the second fastener driver is positioned proximally with respect to the first fastener driver, wherein the first fastener driver is configured to be deployed sequentially with respect to the second fastener driver, and wherein the second fastener driver is configured to eject a different quantity of fasteners than the first fastener driver.
