REPOSABLE MULTI-FIRE SURGICAL CLIP APPLIER
First Claim
1. A reposable surgical clip applier, comprising:
- a handle assembly, including;
a housing;
at least one handle movable relative to the housing between a spaced-apart position and an approximated position; and
an inner actuation assembly disposed within the housing and including a proximal pusher and a proximal drive, the inner actuation assembly operably coupled to the at least one handle such that movement of the at least one handle towards the approximated position moves the proximal pusher proximally and the proximal drive distally, and such that movement of the at least one handle towards the spaced-apart position moves the proximal pusher distally and the proximal drive proximally;
a shaft assembly releasably engagable with the handle assembly, the shaft assembly including;
an outer tube;
a jaw assembly supported at a distal end portion of the outer tube; and
an inner drive slidably disposed within the outer tube and operably coupled to the jaw assembly such that distal movement of the inner drive through the outer tube actuates the jaw assembly; and
a clip cartridge assembly releasably engagable within the shaft assembly, the clip cartridge assembly retaining a stack of surgical clips therein and including a distal pusher operably coupled to a distal-most surgical clip of the stack of surgical clips such that distal movement of the distal pusher loads the distal-most surgical clip into the jaw assembly when the clip cartridge assembly is releasably engaged within the shaft assembly,wherein, when the shaft assembly is releasably engaged with the handle assembly and the clip cartridge assembly is releasably engaged within the shaft assembly;
the proximal drive is positioned proximally adjacent the inner drive such that movement of the at least one handle towards the approximated position actuates the jaw assembly, andthe proximal pusher is positioned proximally adjacent the distal pusher such that movement of the at least one handle towards the spaced-apart position loads the distal-most surgical clip into the jaw assembly.

Abstract
A reposable surgical clip applier includes a handle assembly, a shaft assembly releasably engagable with the handle assembly, and a clip cartridge assembly releasably engagable within the shaft assembly. When the reposable surgical clip applier is assembled, a proximal drive of the handle assembly is positioned proximally adjacent an inner drive of the shaft assembly such that movement of handle(s) of the handle assembly towards an approximated position actuates a jaw assembly of the shaft assembly. When the reposable surgical clip applier is assembled, a proximal pusher of the handle assembly is positioned proximally adjacent a distal pusher of the clip cartridge assembly such that movement of the handle(s) towards a spaced-apart position loads a distal-most surgical clip from the clip cartridge assembly into the jaw assembly.
