    摘要： An apparatus for applying surgical fasteners to body tissue comprising:

    a) a body portion (64) extending from a handle portion (62) and defining a longitudinal axis;
    b) an elongated housing (54) defining a proximal section for engagement in a distal end of said body portion and a distal section for mounting a cartridge assembly (60) containing a plurality of surgical fasteners, said cartridge assembly defining a tissue contacting surface, a proximal end, and a distal end;
    c) an anvil member (56) defining a fastener forming surface against which fasteners ejected from said cartridge assembly are driven, said anvil member mounted relative to said cartridge assembly and movable between an open position wherein said fastener forming surface is spaced from said tissue contacting surface and a closed position wherein said fastener forming surface and said tissue contacting surface are in close co-operative alignment;
       wherein the apparatus is characterized by means (602, 604) movably mounted to at least one of said housing and said anvil member for frictionally engaging tissue disposed therebetween to inhibit the movement thereof.

    摘要： A self contained gas powered endoscopic surgical apparatus 50 is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an anvil member 56 and a surgical fastener cartridge member 58 mounted to the distal end of an elongated endoscopic portion 54. A tubular collar 220 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 68 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 means for preventing firing of the instrument after it has been fired a predetermined number of times. A counter (400-406) for displaying the number of times the apparatus has been fired may be provided. A firing interlock (408-414) is also shown which prevents accidental actuation of the firing trigger. A clamping interlock (430-434) is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument.
