Surgical clip applier and method of assembly
First Claim
1. A method of assembling any one of a relatively small, medium and large scaled surgical clip applier, wherein the respective clip appliers are scaled to deliver relatively small, medium and large 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;
placing particularly sized jaws in the lower channel and overlying the drive channel; and
placing a particularly sized wedge plate in lower channel and overlaying at least a portion of the drive channel and the jaws;
providing a 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;
providing a pusher bar in the channel assembly and extending to the handle assembly; and
connecting a motion multiplier system to the pusher bar, wherein the scaling member varies a stroke of the pusher bar upon a firing of either a relatively small, medium or large scaled clip applier to load the respective clip into jaws of the clip applier.

Abstract
Surgical clip appliers are provided including a clip carrier disposed within a channel assembly and defining a channel and a plurality of windows therein; a plurality of clips slidably disposed within the channel of the clip carrier; a wedge plate reciprocally disposed within the channel assembly, the wedge plate including a plurality of apertures formed along a length thereof; and a clip follower slidably disposed within the channel of the clip carrier and disposed proximally of the plurality of clips, the clip follower being configured and adapted for selective engagement with the windows of the clip carrier and the apertures of the wedge plate. The clip follower is configured and adapted to urge the plurality of clips, in a distal direction relative to the clip carrier, upon reciprocal movement of the wedge plate. The clip applier may be adapted to different size clips by the method of replacing modular components.

23. 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. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
