摘要： An adaptor for an end effector is disclosed. The adaptor can include a staple cartridge having a plurality of staple cavities and a plurality of staples positioned in the staple cavities. The adaptor can also include an anvil plate comprising an arrangement of staple-forming pockets that differs from the staple-forming pockets in the anvil of the end effector. The arrangement of staple cavities in the staple cartridge can correspond to the arrangement of staple-forming pockets in the anvil plate. Additionally or alternatively, the staples in the staple cartridge can be misaligned with the staple-forming pockets in the anvil. The adaptor can include a deformable overmold positioned over the anvil plate, and the anvil plate can comprise a stamped metal sheet.

摘要： An anvil for a surgical end effector is disclosed. The anvil can have a staple-forming surface having a plurality of pockets defined therein. The pockets can be nested. A first pocket can include a proximal cup, a distal cup, and a pocket axis can extend between the proximal cup and the distal cup. The pocket can be asymmetric relative to the pocket axis. A central axis can transect the pocket between the proximal cup and the distal cup. The pocket can also be asymmetric relative to the central axis. The pockets can be obliquely oriented relative to a longitudinal axis of the anvil.

摘要： A surgical staple cartridge for use with a surgical end effector that includes a lock member that is movable between a locked configuration wherein a firing member is prevented from axial travel through the surgical end effector and an unlocked configuration wherein the firing member is axially advanceable. The staple cartridge includes a cartridge body that supports a cam assembly therein that is movable between a starting position and an ending position. The cam assembly defines a central axis and includes at least one unlocking feature that is laterally offset from the central axis and is configured to engage the lock member when the cartridge body is seated within the end effector and the cam assembly is in said starting position to thereby move the lock member to the unlocked configuration.
