Abstract

The invention provides a surgical clip applier particularly useful in laparoscopic and other least invasive surgical procedures. The clip applier includes a shaft having a distal end and a proximal end, the shaft defining an axial direction. Means are provided in the shaft for advancing a clip to the distal end. Hook means are fixed to the distal end of the shaft, the hook means having a distal portion disposed transverse to the shaft so as to define a surface facing in a proximal direction for engaging a tissue structure. A pair of movable jaws are mounted at the distal end of the shaft and are axially slidable relative to the hook means for closing a clip on a tissue structure engaged by the hook means. The movable jaws will define a U-shaped slot open in a generally distal direction. Means are further provided for advancing the jaws to a position adjacent the distal portion of the hook means, as well as means for closing the jaws. The clip applier is particularly advantageous in providing the capability to engage a tissue structure in the hook means and reposition the tissue structure and/or hold the tissue structure in tension while a surgical clip is applied.
