1. An apparatus, comprising:
(a) a handle body;
(b) a shaft assembly extending distally from the handle body;
(c) a stapling assembly comprising:
(i) a staple deck fixed relative to the shaft assembly,
(ii) a staple driver, wherein the staple driver is operable to actuate relative to the staple deck between an unfired position and a fired position to drive a plurality of staples into tissue, and
(iii) an elongated coupling member configured to actuate relative to the staple deck and the staple driver;
(d) an anvil configured to selectively couple with the elongated coupling member, wherein the elongated coupling member is operable to actuate the anvil relative to the staple deck when the anvil is selectively coupled with the elongated coupling member; and
(e) a closure system comprising an adjustment body and an elongated closure member extending distally from the adjustment body, wherein the elongated closure member is housed within the handle body, wherein the adjustment body is located proximally relative to the handle body, wherein the closure system is configured to actuate the anvil, while coupled to the elongated coupling member, between a distal position, a first closed position, and a second closed position, wherein the adjustment body is configured to rotate about a first axis to drive the anvil between the distal position and the first closed position, wherein the adjustment body is configured to rotate about a second axis to drive the anvil between the first closed position and the second closed position, wherein the first axis and the second axis extend in different directions and the first axis extends proximal to the handle body.
