    Abstract: An articulable wrist for an end effector includes a distal linkage provided at a distal end of the articulable wrist, a proximal linkage provided at a proximal end of the articulable wrist, and a central channel cooperatively defined by the distal and proximal linkages and extending between the distal and proximal ends. A flexible member is arranged within the central channel and has a first end operatively coupled to the distal linkage and a second end axially movable relative to the proximal linkage. One or more conduits are defined in the flexible member to receive one or more central actuation members extending through the flexible member.

    Abstract: Aspects of the present disclosure are presented for a medical instrument configured to adjust the power level for sealing procedures to account for changes in tissue impedance levels over time. In some aspects, a medical instrument may be configured to apply power according to a power algorithm to seal tissue by applying a gradually lower amount of power over to time as the tissue impedance level begins to rise out of the “bathtub region,” which is the time period during energy application where the tissue impedance is low enough for electrosurgical energy to be effective for sealing tissue. In some aspects, the power is then cut once the tissue impedance level exceeds the “bathtub region.” By gradually reducing the power, a balance is achieved between still applying an effective level of power for sealing and prolonging the time in which the tissue impedance remains in the “bathtub region.”

    IPC: A61B18/14

    Abstract: An end effector of an electrosurgical device may include a discharge port, an aspiration port, two electrodes, and a diverter formed from a porous material. The diverter includes a matrix having voids to receive fluid from the discharge port. A releasable diverter assembly may include an assembly body configured to receive a pair of electrodes and a diverter composed of a porous material. A shaft assembly of an electrosurgical device may include two electrodes and two fluid cannulae. Each cannula may be disposed proximate to a surface of each of the electrodes. An end effector of an electrosurgical device may include a fluid discharge port, two electrodes, and a diverter disposed therebetween. A proximal edge of the diverter may form a secant line with respect to the end of the discharge port so that fluid emitted by the discharge port is disposed on a surface of the diverter.

    Abstract: The present disclosure provides a surgical instrument that includes an end effector having a first jaw, a second jaw that is movable relative to the first jaw, and at least one electrode in the first jaw. The surgical instrument also includes a control circuit configured to provide electrosurgical energy to the at least one electrode and a electrical conductor electrically connected between the end effector and the control circuit. The control circuit includes a shaft control segment and an electrosurgical energy control segment. The shaft control segment is configured to provide a control signal for operating the end effector to the end effector through the electrical conductor. The electrosurgical energy control segment is configured to provide the electrosurgical energy to the at least one electrode through the electrical conductor.

    Abstract: An electrosurgical device is disclosed. The electrosurgical device includes a cartridge configured to be disposed within an elongate channel of an end effector. The cartridge includes an electrode having a plurality of electrode portions disposed along a longitudinal axis of the cartridge. The electrode is configured to electrically couple to a generator. Each electrode portion of the plurality of electrode portions is configured to deliver an amount of energy to a tissue placed proximate thereto. An amount of energy delivered by a first electrode portion of the plurality of electrode portions differs from an amount of energy delivered by a second electrode portion of the plurality of electrode portions.

    Abstract: Various surgical devices are provided for shielding tissue from potentially harmful byproducts generated by surgical devices that use energy to treat tissue. In general, a shield member is provided that includes a connector element for removably connecting the shield member to a surgical device and a shield body configured to extend adjacent to an energy-emitting end effector of the device. When energy is delivered to treated tissue captured by the end effector, the shield body can be configured to serve as a physical barrier between the end effector and tissue adjacent to the treated tissue. In this way, the shield member can protect the adjacent tissue from potentially harmful byproducts of the end effector, e.g., heat and steam, and/or can deflect the byproducts back toward the treated tissue.
