Patent number: 10959737Abstract: 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. The handle assembly includes a proximal drive member and a proximal pusher bar movable through the proximal drive member. When the reposable surgical clip applier is assembled, the proximal drive member of the handle assembly is positioned proximally adjacent an inner drive assembly 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, the 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.Type: GrantFiled: September 26, 2018Date of Patent: March 30, 2021Assignee: COVIDIEN LPInventor: Mohan P V R

Patent number: 10932791Abstract: A reposable surgical clip applier includes a handle assembly, a shaft assembly engagable with the handle assembly, and a clip cartridge assembly including surgical clips engagable within the shaft assembly. The handle assembly includes a trigger, a drive bar coupled to the trigger and including a rack, a pawl configured to engage the rack upon movement of the drive bar, and a release mechanism operable to move the pawl to disengage the pawl from the rack. The shaft assembly includes an outer tube having a pair of jaws supported at a distal end portion thereof and a drive assembly slidably disposed therein. When the shaft assembly is engaged with the handle assembly and the clip cartridge assembly is engaged within the shaft assembly, actuation of the trigger loads a clip into the jaws and cams the jaws towards one another to form the clip about tissue.Type: GrantFiled: September 10, 2018Date of Patent: March 2, 2021Assignee: COVIDIEN LPInventor: Mohan P V R

Patent number: 10849630Abstract: 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. The handle assembly includes at least one handle, a proximal drive member, a proximal pusher, and a handle spring assembly configured to bias the handle(s) towards a spaced-apart position. When the reposable surgical clip applier is assembled, the proximal drive member is positioned proximally adjacent an inner drive assembly of the shaft assembly such that movement of the handle(s) towards an approximated position actuates a jaw assembly of the shaft assembly. When the reposable surgical clip applier is assembled, the proximal pusher is positioned proximally adjacent a distal pusher of the clip cartridge assembly such that movement of the handle(s) towards the spaced-apart position loads a distal-most surgical clip from the clip cartridge assembly into the jaw assembly.Type: GrantFiled: September 26, 2018Date of Patent: December 1, 2020Assignee: COVIDIEN LPInventor: Mohan P V R

Patent number: 10743887Abstract: 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. The handle assembly includes a proximal drive member, a proximal pusher, and a proximal biasing member biased to move the proximal drive member proximally such that the proximal pusher bar is moved distally. When the reposable surgical clip applier is assembled, the proximal drive member is positioned proximally adjacent an inner drive assembly of the shaft assembly and the proximal pusher is positioned proximally adjacent a distal pusher of the clip cartridge assembly, such that, movement of handle(s) of the handle assembly towards an approximated position actuates a jaw assembly of the shaft assembly and movement of the handle(s) towards the spaced-apart position loads a distal-most surgical clip from the clip cartridge assembly into the jaw assembly.Type: GrantFiled: September 26, 2018Date of Patent: August 18, 2020Assignee: COVIDIEN LPInventor: Mohan P V R
