  • Patent number: 10653413
    Abstract: A surgical instrument that comprises an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective pivotal travel about an articulation axis that extends transversely relative to the shaft axis. An articulation driver is supported for selective longitudinal travel relative to the elongate shaft assembly in a distal direction and a proximal direction. A central articulation link is movably coupled to a distal end of the elongate shaft assembly. The central articulation link is operably coupled to the articulation driver and an end effector driver link. The end effector driver link is operably coupled to the surgical end effector for selective pivotal and axial travel relative thereto.

  • Publication number: 20190247047
    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: 20190183502
    Abstract: Various systems and methods of controlling a surgical instrument are disclosed. The surgical instrument includes a motor, a current sensor configured to sense a current drawn by the motor, and a control circuit coupled to the motor and the current sensor. The motor can be coupled to a clamping member, which is configured to transition an end effector between an open position and a closed position, cut tissue, and/or eject staples from a staple cartridge in the end effector. The control circuit can be configured to detect whether the current drawn by the motor exceeds a threshold via the current sensor and, upon detecting that the current drawn by the motor exceeds the threshold, control the motor to change a speed at which the clamping member is driven.
