SURGICAL CLIP APPLIER
First Claim
1. A surgical clip applier for applying surgical clips to body tissue, the surgical clip applier comprising:
- a housing;
at least one handle pivotably connected to the housing;
a channel assembly extending distally from the housing;
a clip carrier disposed within the 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 drive channel reciprocally disposed within at least one of the housing and the channel assembly, the drive channel having a first end operatively connected to the at least one handle and a second end operatively connected to a distal end of the channel assembly;
a wedge plate reciprocally disposed within the channel assembly, the wedge plate being operatively connected to the at least one handle and including a plurality of apertures formed along a length thereof;
a pusher bar reciprocally positioned within the housing and the channel assembly, the pusher bar having a proximal end operatively connected to at least one handle and a distal end defining a pusher, wherein the distal end of the pusher bar is configured for engagement with a distal-most clip of the plurality of clips; and
a motion multiplier system having a plurality of linkage members configured to distally move the pusher bar by an incremental amount upon an initial actuation of the handles, and configured to proximally move the pusher bar and the wedge plate subsequent to the initial actuation of the handles.
