A self contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an anvil member and a surgical fastener cartridge member mounted to the distal end of an elongated endoscopic portion. A tubular collar of the endoscopic portion moves distally to engage the anvil member and bias the anvil member and the cartridge member into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and the cartridge member. A self contained pneumatic system is disposed in the surgical apparatus and is actuable to eject and/or form the surgical fasteners in the clamped body tissue. The apparatus further comprises a locking mechanism for preventing approximation of the anvil member and the cartridge. In one embodiment, a clamping interlock is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument. In a second embodiment, a clamping interlock is shown which directly engages the tubular collar preventing approximation of the jaws when a cartridge member is not fully inserted. In a third embodiment, a clamping interlock is shown which directly engages the tubular collar when an unfired cartridge is not present or properly inserted into the instrument.
A surgical apparatus for approximating surgical jaw structure comprising: a) a handle; b) an elongated portion defining a longitudinal axis and extending distally from said handle; c) first jaw means mounted to said elongated portion and having a first tissue engaging surface for supporting tissue,
A surgical apparatus for approximating surgical jaw structure comprising: a) a handle; b) an elongated portion defining a longitudinal axis and extending distally from said handle; c) first jaw means mounted to said elongated portion and having a first tissue engaging surface for supporting tissue, said first jaw means comprising a cartridge holding a plurality of ejectable surgical fasteners and a cam bar adapter removably mounting means for ejecting said surgical fasteners from said cartridge; d) second jaw means, mounted to said elongated portion, having a second tissue engaging surface and a distal end and a proximal end, said second jaw means being mounted with respect to said elongated housing such that at least the distal end of said second jaw means is movable in directions generally transverse to said longitudinal axis between an open position spaced from said first tissue engaging surface and a closed position wherein said second tissue engaging surface is in close cooperative alignment with said first tissue engaging surface; e) means associated with said elongated portion for moving said second jaw means between said open position and said closed position comprising a camming member axially movable with respect to said second jaw means, said camming member being movable between a first position and a second position, said camming member cooperating with said second jaw means such that when said camming member is moved from said first position to said second position, said second jaw means is urged to said closed position; f) lockout means associated with said elongated portion for arresting movement of said means for moving said second jaw means between said open position and said closed position, said lockout means comprising pawl member mounted with respect to said elongated portion; and g) means for actuating said means for ejecting said surgical fasteners: wherein said actuating means urges said pawl into engagement with said camming member when said cam bar adapter is located distally from a proximal-most end of said cartridge and said camming member is in said first position to arrest movement of said camming member.
