  • Publication number: 20250255636
    Abstract: A surgical instrument includes an end effector having a clamp arm pivotable relative to an ultrasonic blade, an articulation section configured to deflect the end effector, an acoustic waveguide having a distal portion extending along an axis, a clamp arm closure assembly comprising a body configured to actuate in order to drive the pivoting of the clamp arm, and a clamp arm clocking assembly. The clamp arm clocking assembly is capable of driving rotation of the clamp arm about the axis relative to the ultrasonic blade between a first clocked position and a second clocked position. The clamp arm clocking assembly includes a rotating body pivotally coupled with the clamp arm, a translating drive extending through the articulation section, and a rotation driver assembly. The rotation driver is in communication with the translating driver to convert translational motion of the translating driver into rotational motion of the rotating body.

  • Publication number: 20230404695
    Abstract: An end effector includes a wrist having a distal clevis rotatably coupled to a proximal clevis, a shaft coupled to the proximal clevis and defining a radial shoulder, one or more jaw members rotatably mounted to the distal clevis, and a protective sleeve extendable over the wrist and a portion of the shaft and providing a cylindrical body having opposing distal and proximal ends, the protective sleeve being made entirely of a same flexible, and the cylindrical body defining an aperture at the distal end through which the jaw members protrude. An inner surface of the protective sleeve is smooth and forms an interference fit with an outer surface of the portion of the shaft. A positive indicator is discernible when the protective sleeve has moved from an assembled position, where the proximal end of the protective sleeve engages the radial shoulder, to a migrated position.

  • Patent number: 11690642
    Abstract: An ultrasonic surgical instrument and method of deflecting an end effector include an acoustic waveguide with a proximal waveguide body portion defining a longitudinal axis, a distal waveguide body portion having an ultrasonic blade distally projecting therefrom, and an articulation body portion extending between the proximal and distal waveguide body portions. The articulation body portion of the acoustic waveguide is configured to flex a first direction to thereby deflect the ultrasonic blade relative to the longitudinal axis and through a first plane. In addition, the articulation body portion of the acoustic waveguide is further configured to flex a second direction to thereby deflect the ultrasonic blade relative to the longitudinal axis and through a second plane. The second direction is different than the first direction such that the second plane is different than the first plane for multiplanar deflection of the ultrasonic blade relative to the longitudinal axis.

  • Publication number: 20230049889
    Abstract: A surgical instrument includes an end effector, a shaft assembly, and an axial location feature. The end effector includes an ultrasonic blade and a clamp arm that can move between an open and closed position. The shaft assembly includes a proximal shaft portion, an acoustic waveguide extending proximally from the ultrasonic blade, a distal shaft portion extending along a distal axis, and an articulation section interposed between the proximal shaft portion and the distal shaft portion. The articulation section can deflect the distal shaft portion and the end effector relative to the longitudinal axis between a non-deflected position and a deflected position. The axial location feature can inhibit the ultrasonic blade from shifting relative to the clamp arm along the distal axis as the end effector is driven between the non-deflected position and the deflected position.
