The clip applier of the current invention solves the problems of prior art tools by incorporating a pre-clamp mechanism, the function of which is to pre-clamp the vessel to be ligated to a dimension such that the center leg of the spring of the ligation clip need be lifted only slightly. In this manner the spring clip can be slid over the smaller pre-clamped dimension. This insures that the clip spring material will remain within its elastic limit while allowing the tool to maintain a low profile for use in endoscopic surgery, even on large diameter vessels.
