Abstract

A surgical clip applying instrument is disclosed which includes a handle portion having a first handle and a second handle mounted for relative movement. The handles define a single closing stroke between an open position and a closed position. The closing stroke includes an initial throw, an intermediate throw, and a final throw. The clip applying instrument includes body portion extending distally from the handle portion and defining a longitudinal axis, and a plurality of surgical clips disposed within the body portion. A jaw assembly including first and second jaw portions is mounted at the distal end portion of the body portion and is movable between an approximated position and a spaced position. A jaw control mechanism is configured to move the jaw portions to the spaced position for reception of a distalmost clip in response to the initial throw of the handles. The jaw control mechanism is configured to maintain the jaw portions in the spaced position during the intermediate throw of the handles. In addition, the jaw control mechanism is configured to move the jaw assembly to the approximated position to deform the distalmost clip in response to the final throw of the handles. A clip advancer is also provided to individually distally advance the distalmost clip to the jaw assembly during the intermediate throw of the handles. A method for assembly of a surgical instrument is also disclosed.
