  • Patent number: 12262958
    Abstract: A robotic surgical system includes an eye gaze sensing system in conjunction with a visual display of a camera image from a surgical work site. Detected gaze of a surgeon towards the display is used as input to the system. This input may be used by the system to assign an instrument to a control input device (when the user is prompted to look at the instrument), or it may be used as input to a computer vision algorithm to aid in object differentiation and seeding information, facilitating identification/differentiation of instruments, anatomical features or regions.

  • Patent number: 12193778
    Abstract: A surgical instrument includes an elongate shaft, a proximal clevis on the distal end of the shaft, a distal clevis coupled to the proximal clevis, and an end effector assembly. The distal clevis includes a proximally extending portion and a pair of bosses in fixed positions on the proximally extending portion. A first pin couples the end effector assembly to the distal clevis. A second pin, which has an axis perpendicular to the axis of the first pin, extends through the bosses to couple the proximal and distal clevises. Tendons extend from the end effector assembly around pulleys disposed on the bosses and through the shaft.

  • Patent number: 12186049
    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.

  • Patent number: 12144573
    Abstract: A robotic surgical system configured to control movement of a first instrument and a second instrument, each of which is on a robotic manipulator. In described modes of operation, movement of the first instrument is surgeon controlled based on surgeon input to the robotic system. Movement of the second instrument is also surgeon controlled, but its motion is defined by the chosen mode of operation which sets the amplitude and direction of the second instrument's motion relative to the actual or instructed motion of the first instrument. In this way, two instruments are simultaneously moved based on input from a single surgeon input device.

  • Patent number: 12133698
    Abstract: A surgical system includes a drive unit on a support. The drive unit includes motors or other actuators and a plurality of output elements arranged such that operation of each drive unit linearly translates a corresponding one of the output elements. A surgical device has actuation elements extending through an elongate shaft to a distal articulation section, and an input subsystem carried at the proximal end of the shaft. Linear translatable input elements or pistons of the input subsystem are each associated with a corresponding one of the actuation elements. The input and output elements are positioned such that operation of an actuator linearly translates an output element, causing linear translation of a corresponding input element and engagement of an actuation element. A sterile drape is positionable between the input elements and the output elements.

  • Publication number: 20240358439
    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.

    Abstract: A surgical system includes a light source, a sensor for detecting light, and a surgical device including an elongate shaft having a distal part positionable at a surgical working site within a body cavity. A first optical pathway transmits light from the light source to a distal part of the elongate shaft and onto tissue within the body cavity, and a second optical pathway receives light from tissue within the body cavity and transmits the received light to the sensor. A surgical barrier, such as one covering a robotic manipulator arm housing components of the system, is positioned such that at least the first or second optical pathway includes an optically transmissive portion of the surgical barrier.

  • Patent number: 12059227
    Abstract: In a method of using a haptic interface for a robot-assisted surgical system, input is received in response to movement of fingers of a human hand. In response to the input, a surgical instrument on a robotic manipulator is moved or actuated. Force input is received from force sensors of the surgical system corresponding to forces against the surgical instrument. In response to the force input, fluid is caused to move into one or more bladders mounted to fingers of the human hand to provide tactile feedback to the user.

  • Patent number: 12053256
    Abstract: A powered user interface for a robotic surgical system operates in accordance with a mode of operation in which the actuators are operated to permit motion of the handle in pitch and yaw motion constrained with respect to a virtual fulcrum in a work space of the user interface, and insertion motion is constrained along an axis passing through the virtual fulcrum. In a virtual fulcrum setting mode, a user is prompted to give input to the system selecting a desired point in space for the virtual fulcrum. The selected point in space is then set as the virtual fulcrum.

  • Patent number: 12042240
    Abstract: A system augments a surgical procedure by providing information to the user about regions of a surgical site the user is viewing on a displayed endoscopic image. The system uses an eye tracker to determine the region of the displayed image being viewed by the user, and applies computer vision to the image data to identify structures, conditions or disease states within the region. The system provides information to the user, generates alerts, or modifies operational settings for surgical devices based on the identified structures, conditions or disease states.
