  • Patent number: 11872687
    Abstract: A method of controlling a robotic arm in a surgical system comprises manually applying a force to a body of the robotic arm. Force information is received from ae force sensor on the robotic arm and a controller determines, using the force information, whether the force is a gesture force input. If the force is determined to be a gesture force input, the controller initiates electromechanical movement of the manipulator arm to a draping configuration, instrument attachment configuration, storage configuration, or home configuration.

  • Publication number: 20230210606
    Abstract: An position sensor such as an IMU is removably positioned on a patient bed used to support a patient during a robotic surgical procedure in which a robotic manipulator is used to manipulate a surgical instrument. When the bed is moved during the course of surgery, signals corresponding to a sensed changed in the bed's position are received by a processor, which causes a corresponding repositioning of the robotic manipulator.

  • Patent number: 11148297
    Abstract: A method of controlling a robotic arm in a surgical system comprises manually applying a force to a body of the robotic arm. Force information is received from a gesture force sensor on the robotic arm and a controller determines, using the force information, whether the force is a gesture force input. If the force is determined to be a gesture force input, the controller initiates a predetermined system function. The predetermined system function may be a change in operational state, movement between operational modes, or a movement from a first configuration of the arm's joints to a second, predetermined, configuration of the arms joints.

  • Publication number: 20210256719
    Abstract: A system for measuring distances within a surgical site includes a camera positionable to capture 3D image data corresponding to a treatment site. Using the image data, the system determines the relative 3D positions of identified measurement points at the treatment site captured in the images, and it estimates or determines the distance between the measurement points. Output is generated communicating the measured distances to the user. The measurement taken follows the 3D topography of the tissue positioned between the measurement points.

  • 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.
