Patent number: 5584425Abstract: 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.Type: GrantFiled: August 2, 1995Date of Patent: December 17, 1996Assignee: United States Surgical CorporationInventors: Robert C.
