Surgical clip applier and method of assembly

A method of assembling any one of a plurality of various scaled clip appliers, wherein the respective clip appliers are scaled to deliver relatively scaled surgical clips, the method comprising the steps of:

• assembling a channel assembly including the steps of:
• providing a lower channel;
• placing a drive channel in the lower channel, wherein the drive channel is capable of axial reciprocation in the lower channel;
• placing particularly sized jaws in the drive channel, wherein the jaws are approximated upon a distal advancement of the drive channel relative to the jaws;
• and
• placing a particularly sized wedge plate in the lower channel and overlaying at least a portion of the drive channel and the jaws, wherein the wedge plate is capable of axial reciprocation in the lower channel, and wherein the wedge plate has a distal position in which a distal end of the wedge plate is interposed in the jaws;
• providing a selected housing for a handle assembly;
• connecting the channel assembly to the housing, wherein the channel assembly includes a plurality of respectively scaled surgical clips loaded therein;
• and
• connecting a motion multiplier system to a pusher bar of the clip applier, wherein the motion multiplier system varies a stroke of the pusher bar upon a firing of any scaled clip applier to load the respectively scaled surgical clip into jaws of the clip applier.
