The first jaw (32) has proximal (32a), central (32b), and distal portions (32c). The central portion (32b) includes a first tissue contacting surface and defines a cavity (33). The second jaw (34) includes a second tissue contacting surface and is rotatably secured to the first jaw (32) about a rotation axis. The rotation axis is parallel to the end effector axis. The second jaw (34) has a folded position such that the second jaw (34) is positioned within the cavity (33) of the first jaw (32) with the first and second tissue contacting surfaces parallel to one another and facing in the same direction and a clamped position such that the first and second tissue contacting surfaces oppose one another.
