A surgical instrument comprising: (a) an anvil; (b) a staple applying assembly, wherein the staple applying assembly comprises: (i) a distal surface defining openings, and (ii) a driver operable to drive an annular array of staples through the openings of the distal surface and into tissue; (c) an adjustment member, wherein 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, wherein the adjustment member comprises: (i) a first section, and (ii) a second section, wherein the first and second sections are configured to cooperate in a state of tension to maintain a selected gap distance between the anvil and the distal surface; (d) a user input feature in communication with the driver, wherein user input feature is operable to actuate the driver to thereby drive the staples; and (e) a bailout assembly in communication with the adjustment member, wherein the bailout assembly is operable to selectively separate the first section of the adjustment member from the second section of the adjustment member to thereby relieve the tension characterised in that the first section of the adjustment member has a first threaded portion, wherein the second section has a second threaded portion; wherein the bailout assembly comprises a coupling member, wherein the coupling member includes a first thread set and a second thread set, wherein the first thread set is engaged with the first threaded portion of the adjustment member, wherein the second thread set is engaged with the second threaded portion; and wherein the first thread set of the coupling member has a thread pitch orientation that is opposite to a thread pitch orientation of the second thread set of the coupling member. (a) an anvil; (b) a staple applying assembly, wherein the staple applying assembly comprises: (i) a distal surface defining openings, and (ii) a driver operable to drive an annular array of staples through the openings of the distal surface and into tissue; (i) a distal surface defining openings, and (ii) a driver operable to drive an annular array of staples through the openings of the distal surface and into tissue; (c) an adjustment member, wherein 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, wherein the adjustment member comprises: (i) a first section, and (ii) a second section, wherein the first and second sections are configured to cooperate in a state of tension to maintain a selected gap distance between the anvil and the distal surface; (i) a first section, and (ii) a second section, wherein the first and second sections are configured to cooperate in a state of tension to maintain a selected gap distance between the anvil and the distal surface; (d) a user input feature in communication with the driver, wherein user input feature is operable to actuate the driver to thereby drive the staples; and (e) a bailout assembly in communication with the adjustment member, wherein the bailout assembly is operable to selectively separate the first section of the adjustment member from the second section of the adjustment member to thereby relieve the tension
