Abstract
Abstract 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.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
178 words
A method of ligating a vessel or duct during surgery comprising the steps of; a. placing into a surgical field a ligation clip to be applied to such vessel or duct and a pre-clamping means with opposing clamping surfaces the ligation clip being placed into the surgical field by a structure which carries the ligation clip; b. positioning such vessel or duct within the opposing clamping surfaces of said pre-clamping means with the opposing clamping surfaces lying in a plane relative to said vessel or duct; c. closing said opposing clamping surfaces of said pre-clamping means substantially in said plane around such vessel or duct to effectuate a compression of a portion of the vessel or duct; d. opening the ligation clip; e. positioning the opened ligation clip around the compressed portion of the vessel or duct; f. closing the ligation clip around the compressed portion of the vessel or duct resulting in ligation of the vessel or duct; and g. releasing the ligation clip from the structure used to carry the ligation clip into the surgical field.
