  • Patent number: 12478431
    Abstract: A system and method for providing visual assistance to a practitioner during a medical suturing procedure. Real time images of the suture site are captured and displayed on an image display. The images are analyzed in real time to detect the suture needle, suture penetration sites, relevant tissue, adjacent tissue edges or other features of interest in the visual images. Based on the orientation of, or relationship between, the detected features of interest, overlays are generated and displayed on the image display to inform the user about the suturing task that is underway, such as the anticipated needle path, the suture spacing, or the separation between sutures and adjacent tissue edges.

  • Patent number: 12459125
    Abstract: A system and method fort determining the relative positions of robotic manipulators makes use of a camera positioned in an operating room so as to capture images or portions of first and second robotic manipulators that are positioned outside a patient body cavity. The camera captures images of first and second robotic manipulators, the images are analyzed in real time to determine a relative distance between the first robotic manipulator and the second robotic manipulator. The system determines whether the relative distance is below a predetermined threshold, and, if it is, initiates a collision avoidance measure.

  • Patent number: 12408996
    Abstract: In a system and method conveying suture force information in surgery, real times images of a surgical site are captured and displayed on a display. A suture is engaged using at least one surgical instrument, which in some cases is a robotic surgical instrument. The system determines a tension in the suture using force data obtained from force sensors associated with the instrument or a robotic manipulator used to manipulate the instrument, or using computer vision techniques applied to the captured images. An overlay is generated and displayed on the display depicting the determined tension.

  • Patent number: 12350112
    Abstract: A system and method allow creation of surgical annotations during surgery. A digital image of a treatment site in a region of patient anatomy is captured using a camera and is displayed on an image display. The system displays an overlay marking an anatomic region of interest in the displayed image. During the course of the surgery, panning of the image results in the anatomic region of interest being outside the displayed field of view. In response to user input, the displayed image is subsequently panned such that the anatomic region of interest and the displayed overlay return to the displayed field of view.

  • Patent number: 12283062
    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.

  • Patent number: 12274518
    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.

  • 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: 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.

  • 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.
