A method of assembling any one of a relatively small, medium and large clip applier for delivering relatively small, medium and large clips includes providing a housing for a handle assembly, selecting a channel assembly, connecting the channel assembly to the housing, providing a pusher bar in the selected channel assembly that extends to the handle assembly, and connecting a motion multiplier system to the pusher bar. The channel assembly is selected from a first channel assembly containing small surgical clips, a second channel assembly containing medium surgical clips, and a third channel assembly containing large surgical clips. Each channel assembly has an associated stroke length. The motion multiplier system varies the stroke 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 clips into jaws of the clip applier. |
