  • Publication number: 20210059681
    Abstract: A reposable surgical clip applier includes a handle assembly, a shaft assembly, and a clip cartridge assembly. The shaft assembly includes a pair of jaws and a drive assembly. The clip cartridge assembly includes a stack of surgical clips supported therein and a clip pusher. When the shaft assembly is releasably engaged with the handle assembly and the clip cartridge assembly is releasably engaged within the shaft assembly, a pusher bar of the drive assembly is operably positioned relative to the clip pusher and the handle assembly is operably associated with the drive assembly such that actuation of a trigger of the handle assembly moves the pusher bar distally to load the distal-most clip of the stack of surgical clips into the pair of jaws and moves the jaws-engaging portion distally to cam the pair of jaws towards one another to form the distal-most clip about tissue.

  • Publication number: 20200315629
    Abstract: A reposable surgical instrument includes a handle assembly and an endoscopic assembly releasably engagable with the handle assembly. The handle assembly includes a housing, a drive bar supporting a ratchet pawl, and a trigger coupled to the housing and the drive bar. The endoscopic assembly includes a proximal hub including a ratchet rack, an elongated shaft extending from the proximal hub and supporting an end effector assembly at a distal end thereof, and a drive assembly operably coupled to the end effector assembly. In use, movement of the trigger from an un-actuated position towards an actuated position translates the drive bar from a proximal position towards a distal position to engage the ratchet pawl with the ratchet rack such that further distal translation of the drive bar towards the distal position incrementally urges the drive assembly from the un-fired position towards the fired position.
