  • Publication number: 20210052276
    Abstract: A method includes positioning a surgical tool with an end effector adjacent a surgical site, the end effector including a housing having a tapered section that defines an inner surface, first and second arcuate jaw members protruding distally from the housing and defining a channel therebetween, each arcuate jaw member exhibiting a curved profile shaped to receive an arcuate surgical clip, and a feedbar movable within the housing. The method further including urging the arcuate surgical clip against the inner surface, advancing the feedbar within the housing to engage and follow the inner surface and thereby flexing the feedbar downward and into engagement with the arcuate surgical clip, advancing the arcuate surgical clip with the feedbar into interposition between the first and second arcuate jaw members, and collapsing the first and second arcuate jaw members to crimp the arcuate surgical clip.

  • Patent number: 10828043
    Abstract: End effectors with increased clip loading capacity include those configured to dispense arcuate surgical clips. Such end effectors may comprise: a housing; and first and second arcuate jaw members protruding distally from the housing. Each arcuate jaw member has a curved profile and is shaped to receive an arcuate surgical clip having a complementary curved profile therebetween. Surgical tools may comprise the end effectors operably coupled to the distal end of an elongate shaft.

  • Patent number: 10765434
    Abstract: An end effector for a surgical clip applier includes a body having, a clip revolver rotatably coupled within a bore of the body and containing one or more surgical clips, a torsion member constrained between the body and the clip revolver to exert rotational force on the clip revolver, and a clip advancer that is slidingly coupled within an inner bore of the clip revolver. The inner bore of the clip revolver includes a plurality of grooves in which the clip advancer may translate. The clip advancer aligns with a distal-most surgical clip as it travels within a first of the grooves. The torsion member rotates the clip revolver as the clip advancer travels distally from the first groove so that the clip advancer travels into a second groove of the grooves, such that the clip advancer is in alignment with a second distal-most surgical clip.
