Abstract

A surgical instrument includes an anvil, a staple applying assembly, an adjustment member, a user input feature, and a bailout assembly. The staple applying assembly includes a distal surface defining openings and a driver that is operable to drive an annular array of staples through the openings of the distal surface and into tissue. The adjustment member is operable to adjust the position of the anvil to thereby vary a gap distance defined between the anvil and the distal surface. The adjustment member includes a first section and a second section. The user input feature is operable to actuate the driver to thereby drive the staples. The bailout assembly is operable to selectively separate the first section of the adjustment member from the second section of the adjustment member.
