Abstract

An end effector for use to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, has a formed configuration in which a first portion of a first staple leg and a second portion of a second staple leg are bent relative to a crown and cross the midpoint of the crown and one of the first portion and the second portion overlaps the other of the first portion and the second portion.

Claims26

Dependent claims

An end effector for stapling and cutting an anatomical structure, the end effector comprising:

(a) an anvil that includes:
(i) a first anvil end, a second anvil end, and an anvil face;
(ii) an anvil blade channel defined by the anvil face, wherein the anvil blade channel is positioned to bisect the anvil face into a first half and a second half;
and
(iii) a plurality of staple pockets positioned on the anvil face;
and
(b) a cartridge housing a plurality of staples wherein the cartridge includes a cartridge first end, a cartridge second end, and a cartridge face defining a cartridge blade channel, wherein the cartridge comprises a first plurality of interlocking and separable magazines arranged linearly along a first side of the cartridge blade channel, at least one of the first plurality of separable magazines including a plurality of staple rows, wherein the cartridge comprises a second plurality of interlocking and separable magazines arranged linearly along a second side of the cartridge blade channel, at least one of the second plurality of interlocking and separable magazines including a plurality of staple rows, magazines including a plurality of staple rows, wherein at least one of the anvil face and the cartridge face has a stepped configuration including at least two segments that are offset from one another, wherein the cartridge includes the plurality of staples each having an open leg length and the open leg length of one staple in one of the at least two segments is different from the open leg length of one staple in another of the at least two segments, and
(c) a blade, the blade having a cutting edge, wherein the blade is movable in the anvil blade channel and the cartridge blade channel.
