#$%^&*AU2015200015A120150129.pdf#####SURGICAL CLIP APPLIER AND METHOD OF ASSEMBLY ABSTRACT A surgical clip applier (100) comprises a housing (104) at least one handle (102) pivotably connected to opposite sides of the housing. A channel assembly (108) fixed to and extending from the housing. A pair of jaws (110) supported on and extending from a distal end of the channel assembly. A clip carrier (170) disposed within said channel assembly and defining a channel. A plurality of clips (C) slidably disposed within said channel of said clip carrier. A clip follower (174) slidably disposed within said channel of said clip carrier at a location proximal of said plurality of clips. A drive channel (140) translatably disposed within at least one of said housing and said channel assembly. The drive channel having a first end operatively connected to at least one of said handles and a second end configured and dimensioned to selectively engage said pair of jaws to effectuate closure thereof. A pusher bar (160) translatably disposed within at least one of said housing and said channel assembly. The pusher bar being connected to said drive channel via a motion multiplier system. A distal end of said pusher bar being configured to engage a distal-most clip of the plurality of clips. A wedge plate (180) reciprocally disposed within at least one of said housing and said channel assembly, wherein a distal end of said wedge plate is selectively insertable between said pair of jaws to maintain said pair of jaws spread apart when the wedge plate is in a distal-most position. A motion reversing mechanism including a first end connected to said drive channel, and a second end connected to said wedge plate and engageable by said pusher bar, wherein distal translation of said drive channel causes said pusher bar to translate distally via said motion multiplier system and wherein distal translation of said drive channel causes said pusher bar and said wedge plate to translate proximally, v
