    摘要： A surgical stapling instrument includes an elongate body portion defining a longitudinal axis, and an end effector supported on a distal portion of the elongated body portion. The end effector includes a housing having a base portion and a jaw portion, an anvil assembly supported on the jaw portion, and a cartridge assembly releasably supported on the base portion. A tissue guide member is operably secured relative to the cartridge assembly to facilitate alignment of the cartridge assembly through a firing stroke.

    摘要： A surgical stapling device includes a tool assembly having a U-shaped frame, an anvil assembly, and a cartridge assembly. The U-shaped frame has a proximal transverse portion, a longitudinal portion, and a distal transverse portion. The distal transverse portion and the proximal transverse of the U-shaped frame and the cartridge assembly have a common shape including a first linear portion defining a first axis, a second linear portion defining a second axis, and a third linear portion defining a third axis, the first axis being transverse to the longitudinal axis of the elongate body. In embodiments, a first radius of curvature is defined between the first linear portion and the second linear portion such that the first axis and the second axis define an angle β, and a second radius of curvature is defined between the second linear portion and the third linear portion such that the second axis and the third axis define an angle Ω.

    摘要： A surgical stapling device includes a removable or releasable cartridge assembly. The surgical stapling device and the cartridge assembly include engagement members for releasably securing a thrust bar of the stapling device to a knife assembly of the cartridge assembly. The stapling device also includes structure to prevent the knife assembly from being disengaged from a cartridge body of the cartridge assembly and for obstructing advancement of the knife assembly within the cartridge body after the stapling device has been fired.

    摘要： A curved cartridge assembly of a surgical stapler includes a staple cartridge, an alignment pin received in the staple cartridge and configured to engage an opening in an anvil assembly, and a shipping cap configured to detachably couple to the staple cartridge. The shipping cap has is engaged with the distal end portion of the alignment pin to resist translation of the alignment pin. With the cartridge assembly loaded into the surgical stapler, upon releasing the shipping cap from the staple cartridge the alignment pin translates into engagement with the opening in the anvil assembly.
