Abstract
A surgical instrument includes a shaft assembly, a stapling assembly disposed at a distal end of the shaft assembly and extending along a central axis, and an anvil configured to selectively couple with the stapling assembly to compress a tissue and form staples in the tissue. The stapling assembly includes a housing assembly that includes a proximal housing and a distal housing. The proximal housing is secured to the shaft assembly and is separable from the distal housing to thereby releasably couple the distal housing with the shaft assembly. The stapling assembly further includes a deck member having an annular array of staple openings configured to receive a plurality of staples, and a knife member at least partially disposed within the housing assembly.
