1. A surgical stapling device comprising:
an elongate body having a proximal portion and a distal portion;
an anvil retainer positioned within the elongate body and movable between retracted and advanced positions, the anvil retainer having a proximal portion and a distal portion and having a longitudinally extending through bore;
an anvil assembly coupled to the anvil retainer, the anvil assembly including an anvil head assembly and a center rod assembly that has a longitudinal axis, the center rod assembly having a through bore and having a proximal portion and a distal portion, the anvil head assembly coupled to the distal portion of the center rod assembly and having a through bore that is aligned with the through bore of the center rod assembly, the through bores of the center rod assembly and the anvil head assembly being aligned with the longitudinally extending through bore of the anvil retainer and the distal portion of the anvil retainer positioned within the through bore of the anvil head assembly; and
a visualization device having a proximal portion and a distal portion, the visualization device extending through the through bores of the anvil retainer and the center rod assembly and positioned within the through bore of the anvil head assembly, the visualization device positioned to facilitate visualization of tissue surrounding the anvil head assembly of the anvil assembly.
