摘要:
#$%^&*AU2007216891B220130502.pdf#####ENDOSCOPIC SURGICAL CLIP APPLIER ABSTRACT OF THE DISCLOSURE An apparatus for application of surgical clips to body tissue includes an actuator at least partially disposed within a body and longitudinally movable in response to 5 actuation of a handle portion. The apparatus includes a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position and a rack having ratchet teeth connected to the actuator. The apparatus includes a pawl engaging a series of ratchet teeth and capable of preventing an inadvertent return of the actuator before full actuation of the apparatus. A clip pusher incrementally moves 1o distally each time a clip is released from the apparatus. When the clip pusher reaches a predetermined distal point in a clip carrying channel, a feed bar is deflected to a second position to prevent retraction but not advancement of the actuator and thereby manipulates the pawl to engage the ratchet teeth.2/71 4* T
