  • Publication number: 20210007752
    Abstract: An apparatus includes a handle assembly, a shaft assembly, and an end effector. The handle assembly includes a body and an actuator. The actuator includes a rotary member that is configured to be driven by a finger of a hand that grasps the handle body. The shaft assembly includes an external sheath that is fixed to the handle body and an inner shaft that is coupled to the actuator. The inner shaft is configured to slide longitudinally relative to the external sheath in response to rotation of the first rotary member relative to the handle body. The end effector is configured to encompass a bodily lumen and includes a flexible member extending distally from the inner shaft. A first coupling element is fixed to the distal tip of the flexible member. A second coupling element is fixed to the external sheath. The flexible member defines an adjustable loop.

  • Publication number: 20200338370
    Abstract: In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.

  • Patent number: 10524854
    Abstract: A surgical instrument can comprise a first jaw and second jaw, wherein the first jaw is movable relative to the second jaw to capture tissue having a tissue thickness. A tissue cutting force monitor is configured to determine the tissue thickness of the captured tissue and communicate the tissue thickness to a controller, wherein the controller is configured to adjust the speed of a tissue-cutting element during a cutting portion of a firing stroke based on the tissue thickness communicated from the tissue cutting force monitor. The controller is configured to reduce the speed of the tissue-cutting element when the tissue cutting force monitor communicates a thicker tissue thickness to the controller. The controller is configured to increase the speed of the tissue-cutting element when the tissue cutting force monitor communicates a thinner tissue thickness to the controller.

  • Publication number: 20180289415
    Abstract: Surgical instruments with position-dependent actuator cooperation and impedance are described herein. In general, movement of one actuator can cause proportional movement of another actuator depending upon the positions of each actuator. In one embodiment, a surgical instrument can include a distal end effector and a proximal actuator portion. First and second actuators coupled to the proximal actuator portion can each be configured to move between a first position and a second position. Further, the first actuator and the second actuator can be configured such that, when the first actuator and the second actuator are in the first position, moving the second actuator to the second position causes the first actuator to move to the second position, and when the first actuator is in the second position, the second actuator can be moved from the first position to the second position independent of the first actuator.
