    摘要: 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 firing of the instrument after it has been fired a predetermined number of times. A counter for displaying the number of times the apparatus has been fired may be provided. A firing interlock is also shown which prevents accidental actuation of the firing trigger. A clamping interlock is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument.

    摘要: A method for percutaneous dissection of a segment of vascular tissue from a patient is provided which includes providing an elongated tubular member having a proximal end and a distal end, and blunt dissection structure positioned adjacent the distal end of the tubular member and remotely actuable from adjacent the proximal end of the tubular member. The method further provides for percutaneously accessing a first end portion of the vascular tissue segment, the blunt dissection structure is positioned adjacent the vascular tissue segment and is actuated to bluntly dissect the vascular tissue segment from surrounding body tissue.
