A feed bar (82) is configured to individually distally advance a surgical clip to the jaw assembly while the jaw portions are in the spaced apart position. An actuation mechanism is at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion, the actuation mechanism including a first angled surface (290). A jaw closure member positioned distally of the actuation mechanism (242) and adjacent the first and second jaw portions (16) to move the jaw portions to the approximated position upon longitudinal movement of the actuation mechanism. A lockout mechanism connected to the feed bar (82), the lockout mechanism including a second angled surface and being configured and dimensioned to cooperatively engage the first angled surface of the actuation mechanism, wherein re-actuation of the apparatus is prevented upon engagement of the first angled surface and the second angled surface and subsequent to the application of a final surgical clip. |
