Methods of stapling tissue
A method of stapling tissue is disclosed. The method can include obtaining a staple cartridge including a plurality of staples, wherein each staple has a base and a leg extending from the base. The stapling method can also include firing the staples from the staple cartridge, wherein the staples are fired into tissue in a staple line. The staple line can include a first portion having a first flexibility and a second portion having a second flexibility, wherein the second flexibility is different than the first flexibility. A method of stapling tissue can also include adapting an anvil with an anvil plate having an arrangement of staple-forming pockets that differs from the staple-forming pockets in the anvil.
1. A staple cartridge for use with a surgical instrument, wherein the staple cartridge comprises:
a cartridge body comprising a longitudinal slot and at least six rows of staple cavities, wherein the longitudinal slot defines a longitudinal axis, and wherein the at least six rows of staple cavities comprises:
a longitudinal row of first staple cavities positioned on a first side of the longitudinal slot, wherein each first staple cavity is oriented at a first angle relative to the longitudinal axis, and wherein the first staple cavities are configured to receive first staples;
a longitudinal row of second staple cavities positioned on the first side of the longitudinal slot, wherein each second staple cavity is oriented at a second angle relative to the longitudinal axis, and wherein the second staple cavities are configured to receive second staples; and
a longitudinal row of third staple cavities positioned on the first side of the longitudinal slot, wherein each third staple cavity is oriented at a third angle relative to the longitudinal axis, wherein the third staple cavities are configured to receive third staples, and wherein at least one of the first angle, the second angle, and the third angle is different from the others.
2. The staple cartridge of claim 1 , wherein the first angle, the second angle, and the third angle are different from each other.
3. The staple cartridge of claim 1 , wherein the first angle comprise an oblique angle, wherein the second angle comprises an oblique angle, and wherein the third angle comprises an oblique angle.
4. The staple cartridge of claim 1 , wherein the at least six rows of staple cavities are arranged symmetrically about the longitudinal slot.
5. The staple cartridge of claim 1 , wherein the at least six rows of staple cavities are arranged so there are three rows of staple cavities on each side of the longitudinal slot.
6. A staple cartridge for use with a surgical instrument, wherein the staple cartridge comprises:
a cartridge body comprising a longitudinal slot defining a longitudinal axis;
a longitudinal row of first staple cavities positioned on a first side of the longitudinal slot, wherein each first staple cavity is oriented at a first angle relative to the longitudinal axis, and wherein the first staple cavities are configured to receive first staples;
a longitudinal row of second staple cavities positioned on the first side of the longitudinal slot, wherein each second staple cavity is oriented at a second angle relative to the longitudinal axis, and wherein the second staple cavities are configured to receive second staples; and
a longitudinal row of third staple cavities positioned on the first side of the longitudinal slot, wherein each third staple cavity is oriented at a third angle relative to the longitudinal axis, wherein the third staple cavities are configured to receive third staples, and wherein at least one of the first angle, the second angle, and the third angle is different from the others.
7. The staple cartridge of claim 6 , wherein the first angle, the second angle, and the third angle are different from each other.
8. The staple cartridge of claim 6 , wherein the first angle comprise an oblique angle, wherein the second angle comprises an oblique angle, and wherein the third angle comprises an oblique angle.
9. The staple cartridge of claim 6 , wherein the staple cartridge further comprises three longitudinal rows of staple cavities positioned on a second side of the longitudinal slot opposite the first side, and wherein the staple cavities one the first side of the longitudinal slot and the second side of the longitudinal slot are arranged symmetrically about the longitudinal axis.
10. A fastener cartridge for use with a surgical instrument, wherein the fastener cartridge comprises:
a longitudinal slot defining a longitudinal axis;
a longitudinal row of first fastener cavities positioned on a first side of the longitudinal slot, wherein each first fastener cavity is oriented at a first angle relative to the longitudinal axis, and wherein the first fastener cavities are configured to receive first fasteners;
a longitudinal row of second fastener cavities positioned on the first side of the longitudinal slot, wherein each second fastener cavity is oriented at a second angle relative to the longitudinal axis, and wherein the second fastener cavities are configured to receive second fastener; and
a longitudinal row of third fastener cavities positioned on the first side of the longitudinal slot, wherein each third fastener cavity is oriented at a third angle relative to the longitudinal axis, wherein the third fastener cavities are configured to receive third fasteners, and wherein the first angle, the second angle, and the third angle are different from one another.
11. The staple cartridge of claim 10 , wherein the first angle comprise an oblique angle, wherein the second angle comprises an oblique angle, and wherein the third angle comprises an oblique angle.
12. The staple cartridge of claim 10 , wherein the fastener cartridge further comprises three longitudinal rows of fastener cavities positioned on a second side of the longitudinal slot opposite the first side, and wherein the fastener cavities one the first side of the longitudinal slot and the second side of the longitudinal slot are arranged symmetrically about the longitudinal axis.
