Surgical apparatus (10) is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus (10) includes an endoscopic body having an elongated proximal portion (12) and an articulating distal portion (14) which moves relative to the proximal portion (12). A cartridge assembly (16) and an anvil member (18) are detachably mounted adjacent the articulating distal portion (14) which move relative to one another between an open position and a closed position. A camming mechanism (20) is associated with the articulating portion (14) of the apparatus (10) for moving the anvil member (18) relative to the cartridge assembly (16), and a linkage system (58,60) is provided for effectuating the articulation of the distal portion (14) of the endoscopic body to increase the range of operability of the apparatus (10).; In addition, a driving mechanism (24) is provided for ejecting the surgical fasteners from the cartridge assembly (16).
