A surgical stapler for placing lateral lines of staples and making an incision, all through an endoscopic tube, includes an anvil member which is mounted to the distal end of an elongated housing. A tubular collar disposed around the arm of the anvil member is movable to a distal position to bias the anvil member and a cartridge assembly into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and cartridge assembly.
A surgical apparatus for driving surgical fasteners into body tissue comprising: a) a frame; b) an endoscopic portion defining a longitudinal axis and extending distally from said frame, said endoscopic portion including: i) an elongated support for receiving a cartridge assembly, the cartridge asse
A surgical apparatus for driving surgical fasteners into body tissue comprising: a) a frame; b) an endoscopic portion defining a longitudinal axis and extending distally from said frame, said endoscopic portion including: i) an elongated support for receiving a cartridge assembly, the cartridge assembly having a distal end and a proximal end and including a plurality of surgical fasteners slidably mounted therein, and having a tissue engaging surface; ii) a jaw member having an external ramped camming surface, a distal end and a proximal end, said proximal end of said jaw member being pivotally retained in said elongated support such that the jaw member is movable between an open position and a closed position in close cooperative alignment with the tissue engaging surface of the cartridge assembly and said distal end of said jaw member is in juxtaposed alignment with said distal end of said cartridge assembly; iii) closure means for moving the jaw member between the open position and the closed position, said closure means including at least a camming surface transverse to said longitudinal axis for contacting said ramped camming surface of said jaw member whereby longitudinal movement of said closure means relative to said jaw member causes said transverse camming surface to contact said ramped camming surface of said jaw member and movement of said jaw member to said closed position; iv) pusher elements for ejecting the surgical fasteners from the cartridge assembly, through tissue; c) gas seal means for sealing said endoscopic portion to obstruct the passage of gaseous media therethrough; and d) means which translates with respect to said endoscopic portion independent of said closure means for actuating said pusher elements.
