A surgical stapling device () includes a reload assembly () having a cartridge assembly () and a shipping cap () releasably attached to the cartridge assembly (). The cartridge assembly () includes an alignment pin assembly () having an alignment pin () defining a key hole slot () and is movable between a locked position and an unlocked position. The shipping cap () includes a locking pin () received through the key hole slot (). When the alignment pin () is in the locked position, the alignment pin () prevents separation of the shipping cap () from the replaceable cartridge assembly () and when the alignment pin () is in the unlocked position, the alignment pin () permits separation of the shipping cap () from the replaceable cartridge assembly ().

Surgical stapling device with shipping cap

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;.
