Abstract:
1. A method of assembling any one of a relatively small scaled surgical clip applier scaled to deliver relatively small surgical clips, a relatively medium scaled surgical clip applier scaled to deliver relatively medium surgical clips, and a relatively large scaled surgical clip applier scaled to deliver relatively large surgical clips, the method comprising the steps of: providing a housing for a handle assembly; selecting a channel assembly from at least a first channel assembly including a plurality of small surgical clips loaded therein, a second channel assembly including a plurality of medium surgical clips loaded therein, and a third channel assembly including a plurality of large surgical clips loaded therein, wherein each of the first, second and third channel assemblies has an associated stroke length required to load one of the respectively scaled clips into jaws of the clip applier upon firing; connecting the selected channel assembly to the housing; providing a pusher bar in the selected channel assembly, wherein the pusher bar extends to the handle assembly; connecting a motion multiplier system to the pusher bar, the motion multiplier system configured to vary a stroke length of the pusher bar in accordance with the associated stroke length such that, upon firing, the pusher bar is translated the associated stroke length to load one of the respectively scaled clips into jaws of the clip applier, the motion multiplier system including an accelerator rack and a bell crank gear; positioning the accelerator rack for slidable disposition within the housing; positioning the bell crank gear for pivotable disposition within the housing; and engaging the bell crank gear with the accelerator rack such that translation of the accelerator rack effects rotation of the bell crank gear.
