  • 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.

  • Publication number: 20200205811
    Abstract: A cartridge for use with a surgical instrument includes a curved body and a deck defined by the curved body and configured to clamp tissue against an anvil. A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot is formed in the deck and is configured to slidably receive a cutting member therethrough. The deck includes a sloped deck portion that slopes away from the arcuate slot in a direction transverse to a length of the arcuate slot. The sloped deck portion is configured to provide varied compression of tissue across a width of the deck.

A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot formed in the deck is configured to slidably receive a cutting member therethrough. An opening formed in the deck adjacent to an end of the arcuate slot is configured to slidably receive a pin therethrough. The cartridge further includes a raised surface offset from the deck and extending circumferentially about at least a portion of the opening. The raised surface is configured to clamp tissue against the anvil to thereby fix the tissue relative to the opening.

  • Patent number: 10639038
    Abstract: A surgical instrument includes a body, a shaft assembly, an end effector, and an electrical contact assembly. The body includes a power source. The shaft assembly extends distally from the body, the end effector is distal of the shaft assembly. The end effector includes a channel assembly and a cartridge assembly. The cartridge assembly may selectively couple with the channel assembly. The cartridge assembly includes an electrically activated component. The electrical contact assembly is configured to electrically couple the power source with the electrically activated component. The electrical contact assembly includes a first electrical contact associated with the channel assembly, a second electrical contact associated with the channel assembly, and a hydrophobic layer extending between the first electrical contact and the second electrical contact.
