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.

An endoscope system is provided, which comprises an endoscope having a hollow tube formed therein, a flexible elongate member having a first end for operational control and a second distal end for operation of robotic members, one or more actuators coupleable to the flexible elongate member at the first end thereof, and an anti-buckling tube arranged with respect to the hollow tube at the first end of the endoscope to prevent buckling of the flexible elongate member during translation of the one or more actuators. Different embodiments are also disclosed, including an endoscope comprising one or more flexible tendons having a wire coil sheath which includes wire having a substantially rectangular cross section, or an endoscope comprising a rotational-motion transmitting device, one or more flexible tendons and one or more electrical wires having anti-kink support thereon, a coupling means constraining the robotic member to an asymmetric range of motion, or torque joint means comprising a centrally aligned pulley for coupling the robotic member.

Methods and systems are disclosed for removing a tattoo from a subject's skin by application of a cold plasma that is delivered via a liquid-gas mixture. The plasma can be delivered in the form of gas bubbles, in which at least a portion of gas is in the form of a plasma.

The present disclosure relates to methods, devices, kits and systems for enhancing the efficacy and longevity of denervation procedures.

An electrosurgical apparatus for treating fluid-filled biological growths by replacing the fluid within the growth with a substance that assists in delivering treatment energy.

The treatment energy may be microwave energy or may be thermal energy derived from microwave energy. The apparatus comprises an instrument having a radiating tip portion, and a fluid delivery mechanism for transporting fluid to and from a treatment zone located around the radiating tip portion. The fluid delivery mechanism comprises a rigid insertion element arranged to extend into the treatment zone, whereby fluid can be aspirated from the treatment zone, and a substance injected into the treatment zone to replace the aspirated fluid. The injected substance has dielectric properties selected to facilitate uniform delivery of treatment energy to biological tissue in the treatment zone.

A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the first or second grasping components is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the first or second grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening therethrough. The first opening is disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

A surgical device which combines cautery and tissue debris conveyance via a combination of suction and an Archimedes screw, the cautery electrode encased within the Archimedes screw, the device comprising a device body housing a motor for rotating the screw, a cannula having an aperture for exposing an instrument, extending from the body portion, and a connector system operatively associated with the body portion, the connector system organized to provide pre-determined relative locations of connection for operably connecting the cannula, a cautery electrode and an Archimedes screw to the device body such the cautery electrode tip is positionable outside the aperture of the cannula and the Archimedes screw is disposed within the cannula in a position for conveying tissue entering the cannula via suction.
