A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.

An adapter assembly of a surgical instrument includes a cam member defining a proximal cam slot and a distal cam slot, a first articulation shaft, and a second articulation shaft. The first articulation shaft has a proximal end portion received in the proximal cam slot, and a distal end portion configured to be coupled to a surgical loading unit. The second articulation shaft has a proximal end portion received in the distal cam slot, and a distal end portion configured to be coupled to the surgical loading unit. The first and second articulation shafts are configured to move in opposing longitudinal directions in response to a rotation of the cam member to articulate the surgical loading unit.
