摘要：
An end effector for a surgical instrument is provided that has a first jaw, such as a cartridge body, having on a tissue-contacting surface thereof a plurality of staple cavities configured to seat staples therein, and a second jaw, such as an anvil, with a plurality of staple forming cavities formed on a tissue-contacting surface thereof. The first jaw has a generally rectangular nominal perimeter defining a regular perimeter around outer rows of the plurality of staple cavities. At least one of the first and second jaws has extension elements extending beyond the nominal perimeter of that jaw such that each of the extension elements has at least one attachment feature formed thereon. An adjunct material having a shape complementary to a shape of the jaw is configured to releasably mate with the attachment features formed on the jaw, via corresponding adjunct's mating features.
