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 method, comprising:
obtaining a staple cartridge comprising a plurality of staples, wherein each staple comprises a base and a leg extending from the base; and
firing the staples from the staple cartridge, wherein the staples are fired into tissue in a staple line, and wherein the staple line comprises:
a first portion comprising a first flexibility; and
a second portion longitudinally offset from the first portion, wherein the second portion comprises a second flexibility, and wherein the second flexibility is different than the first flexibility.
2 . The method of claim 1 , further comprising selecting the staple cartridge from at least two different staple cartridges.
3 . The method of claim 2 , wherein the at least two different staple cartridges comprise different arrangements of staple cavities.
4 . The method of claim 1 , wherein the first portion comprises a distal portion.
5 . The method of claim 1 , wherein the first portion is laterally offset from the second portion.
6 . The method of claim 1 , wherein the first portion comprises a first row of staples, and wherein the second portion comprises a second row of staples.
7 . A method, comprising:
obtaining a staple cartridge comprising a plurality of staples, wherein each staple comprises a base and a leg extending from the base; and
firing the staples from the staple cartridge, wherein the staples are fired into tissue in a staple line, and wherein the staple line comprises:
a first length comprising a first group of the staples, wherein the bases of the staples in the first group are arranged in a herringbone pattern; and
a second length comprising a second group of the staples, wherein the second length is longitudinally offset from the first length, and wherein the bases of the staples in the first group are arranged in parallel.
8 . The method of claim 7 , wherein the first length comprises a first flexibility, wherein the second length comprises a second flexibility, and wherein the second flexibility is different than the first flexibility.
9 . The method of claim 7 , wherein the first length is more flexible than the second length.
10 . The method of claim 7 , further comprising selecting the staple cartridge from at least two different staple cartridges.
11 . The method of claim 10 , wherein the at least two different staple cartridges comprise different arrangements of staple cavities.
12 . A method, comprising:
obtaining an adaptor assembly comprising a staple cartridge and an anvil plate, wherein the anvil plate comprises a plurality of first staple-forming pockets, and wherein the plurality of first staple-forming pockets are arranged in a first arrangement; and
installing the adaptor assembly in an end effector, wherein the end effector comprises an anvil comprising a plurality of second staple-forming pockets, wherein the second staple-forming pockets are arranged in a second arrangement, and wherein the second arrangement is different than the first arrangement.
13 . The method of claim 12 , wherein the first arrangement comprises a herringbone pattern of pockets.
14 . The method of claim 13 , wherein the second arrangement comprises a parallel pattern of pockets.
15 . The method of claim 13 , wherein the staple cartridge comprises a plurality of staple cavities arranged in a corresponding herringbone pattern.
16 . The method of claim 13 , wherein the staple cartridge comprises a plurality of staples arranged in a corresponding herringbone pattern.
17 . The method of claim 16 , further comprising driving the staples into forming contact with the second staple-forming pockets in the adaptor assembly.
18 . The method of claim 13 , wherein the adaptor assembly comprises a deformable material, and wherein said installing step further comprises forming the deformable material to a deformed configuration that corresponds to a profile of the anvil.
19 . The method of claim 13 , wherein said installing step further comprises aligning features on the anvil plate with features on the anvil.
20 . The method of claim 13 , further comprising clamping tissue between the staple cartridge and the anvil plate.
