  • Patent number: 11969218
    Abstract: A system and method provide feedback to guide a user to arrange components of a surgical robotic system in a suitable arrangement for the surgical procedure to be performed. An image of a medical procedure site at which a robotic manipulator and a second object such as a second robotic manipulator, patient table, patient, and bedside staff are located. The image is displayed for a user. The system uses computer vision to recognize the robotic manipulator and second object in the image and determine their relative positions. Based on the type of surgical procedure that is to be performed, the system determines a target position for the robotic manipulator and/or the second object, and displays, as an overlay to the displayed image, a graphical indication of the target position.

  • 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.

  • Patent number: 11638615
    Abstract: An intelligent surgical tool control system, comprising a tool management system; an indicating means to indicate at least one surgical event; a communicable database for storing, for each item of interest, its identity, its present 3D position and at least one previous 3D position; and at least one processor to identify, from a surgical event, an output surgical procedure. The tool management system can comprise a maneuvering mechanism to maneuver a surgical tool in at least two dimensions; and a controller to control at least one of activation and deactivation of a surgical tool and articulation of a surgical tool. The indicating means can indicate a surgical event selected from movement of a moving element and presence of an item of interest, where movement is determinable if the current 3D position of the moving element is substantially different from a previous 3D position of the same.
