  • Publication number: 20210085406
    Abstract: A surgical robotic system has at least two robotic manipulator arms. A user input device has a single handle configured to allow a surgeon to input instructions to the robotic surgical system to cause movement of the first instrument by a first robotic manipulator arm, and to cause movement of the second instrument by a second robotic manipulator arm. The user input device can include a first input handle moveable in multiple degrees of freedom to generate input for movement of the first instrument, and an auxiliary input on the handle to generate input for movement of the second instrument.

  • Publication number: 20210015574
    Abstract: A powered user interface for a robotic surgical system includes a handle on a linkage having a plurality of joints, a base, and actuators. The interface operates in accordance with a first mode of operation in which a plurality of its actuators are operated to constrain predetermined ones of the joints to permit motion of the handle in only 4DOF with respect to the base, and a second mode of operation in which the actuators permit motion of the handle in at least 6DOF with respect to the base.

  • Publication number: 20200375680
    Abstract: A surgical instrument for use with a robotic manipulator includes an end effector assembly having one or two end effector members, each having a distal treatment end, a proximal end, and a tendon pass-through. Each end effector member is sandwiched between a corresponding pair of pulley members that, when assembled define an annular tendon pathway that is between the pulley members and that is aligned with the pass-through. For each end effector member, a tendon having a distal loop portion ends through the tendon pass-through, with its legs passing proximally from the pass-through, extending in opposite directions around the tendon pathway and proximally through the instrument's shaft.

  • Publication number: 20200315722
    Abstract: An electrosurgical instrument having jaws is energized and actuated using a length of cable. The cable is formed of a conductive inner portion coated with a dielectric polymer. The cable extends through a pass-through in a portion of the jaw and is crimped to create a mechanical and electrical connection between the conductive inner portion and the conductive jaw material.

  • Publication number: 20200205909
    Abstract: A robotic system assembly comprises a robotic manipulator including an actuator assembly and a surgical instrument having a base body mountable to the actuator assembly. The base includes a first control input and a second control input, wherein the first and second control inputs are positioned on different sides of the base. The actuator assembly is moveable between open and closed positions to facilitate removal and replacement of surgical instruments. When in the closed positions, drive elements of the actuator assembly are positioned to drive the first and second control inputs of the surgical instrument to cause end effector movement or actuation.

  • Publication number: 20200205910
    Abstract: A user interface for a surgical robotic system includes a plurality of handles, each removably attachable to a user interface assembly by a quick release connector. The selection of handles can include handles of varying size, degree of complexity, handles adapted for laparoscopic motion, handles adapted for true cartesian motion or handles customized to surgeon anthropometric data, etc.

  • Publication number: 20180238883
    Abstract: A robotic surgical system includes a fluid drive system and a surgical instrument removably positioned in operative engagement with the drive system. A sterile barrier covers non-sterile portions of the surgical system. Features of the sterile barrier are used to transfer motion output from the fluid drive system to the instrument for actuation of the instrument.
