  • Publication number: 20240138924
    Abstract: A first ultrasonic beacon transmission includes a first pilot signal and a first encoded information signal. An apparatus may detect the first pilot signal and decode, based on the first pilot signal, the first encoded information signal to identify a medical system associated with the first ultrasonic beacon transmission. Based on the first encoded information signal, the apparatus may enter into a first pairing state in which the apparatus is communicatively paired with the medical system. While the apparatus is operating in the first pairing state and within a threshold time of entering the first pairing state, the apparatus may detect a second pilot signal included in a second ultrasonic beacon transmission, which also includes a second encoded information signal. Based on the detection of the second pilot signal within the threshold time, the apparatus may continue operating in the first pairing state without decoding the second encoded information signal.

  • Publication number: 20230139425
    Abstract: A configuration optimization system determines a reachability of a target object in a surgical space by a robotic instrument of a computer-assisted surgical system for a first configuration of the computer-assisted surgical system. The configuration optimization system determines a second configuration of the computer-assisted surgical system that improves the reachability of the target object by the robotic instrument. The configuration optimization system provides, to the computer-assisted surgical system, data indicating the second configuration.

  • Publication number: 20230126545
    Abstract: An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to obtain one or more operating characteristics of an instrument located in a surgical space; obtain one or more anatomical characteristics associated with the surgical space; and direct a computer-assisted surgical system to automatically perform, based on the based on the one or more operating characteristics of the device and the one or more anatomical characteristics associated with the surgical space, an operation with the instrument located in the surgical space.

  • Publication number: 20230112592
    Abstract: An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to obtain one or more parameters of a non-robotic device in a surgical space, the non-robotic device engaged by a computer-assisted surgical system; generate, based on at least the one or more parameters of the non-robotic device, guidance content for use by the computer-assisted surgical system to facilitate guided teleoperation of the non-robotic device; and provide the guidance content to the computer-assisted surgical system.

  • Publication number: 20230057639
    Abstract: A device pairing system is configured to determine that an auxiliary device detects an ultrasonic beacon emitted by a beacon generator and identify, in response to the determination that the auxiliary device detects the ultrasonic beacon, a medical system associated with the ultrasonic beacon. The auxiliary device is further configured to communicatively pair, in response to the identification of the medical system, the auxiliary device with the identified medical system.

  • Publication number: 20230031641
    Abstract: Methods and systems are provided that can include accessing a three-dimensional (3D) model of an object with a visualization tool including a touchscreen, displaying, via the touchscreen, an image of the 3D model, detecting a pressure based and/or contact based input at the touchscreen, and changing a display parameter of a first component of the 3D model as a result of the input. Selecting the component and/or changing the display can be indicated by visual and/or haptic signals. A method is provided that can include selectively making components of the 3D model transparent or non-transparent, and changing a center of rotation of the 3D model based on the remaining non-transparent components. A method is provided that can include identifying gestures of a selection tool via a stereo camera and changing display parameters based on the detected gesture(s).

  • Publication number: 20220409301
    Abstract: An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to: detect an intent of a user of a computer-assisted surgical system to use a robotic instrument attached to the computer-assisted surgical system to interact with a target object while the target object is located in a surgical space; determine a pose of the target object in the surgical space; and perform, based on the detected intent of the user to interact with the target object and the determined pose of the target object in the surgical space, an operation with respect to the target object.

  • Patent number: 11497569
    Abstract: A method comprises accessing a three-dimensional (3D) model of an object with a visualization tool, including a touchscreen; displaying, via the touchscreen, an image of the 3D model; detecting a first pressure based input at a first location on the touchscreen; selecting a first component of the 3D model as a result of the first pressure based input at the first location; detecting movement of the first pressure based input from the first location on the touchscreen to a second location on the touchscreen; selecting an adjustable display parameter as a result of the first pressure based input at the second location; detecting a second pressure based input at the touchscreen; and while the first component is selected, changing the display parameter of the first component of the 3D model as a result of the second pressure based input.

  • Publication number: 20220323157
    Abstract: A medical system includes one or more processors. The processors are configured to perform operations including receiving image data associated with an anatomic feature from a first imaging device. The image data is associated with a first imaging device space. Probe data associated with the anatomic feature is obtained from a second imaging device. The probe data is associated with a second imaging device space. The probe data is registered to the image data to generate a first registration between the second imaging device space and the first imaging device space. Anatomic model associated with the anatomic feature is registered to the probe data to generate a second registration between a model space of the anatomic model and the second imaging device space. A third registration between the model space and the first imaging device space is generated based on the first registration and the second registration.
