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.

Tissue guide for curved end effectors

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 &#x3b2;, 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 &#x3a9;.
