  • Publication number: 20210315636
    Abstract: A virtual camera may be positioned relative to a 3-D model of a patient anatomy in order to provide a virtual camera view of the surrounding anatomy and tracked surgical instruments being deployed to the anatomy. Visual context provided by the virtual camera may be limited in some cases, such as where a surgical instrument is being used within a very narrow anatomical passageway or cavity. To provide more placement flexibility, an IGS system providing a virtual camera receives inputs defining variable visual characteristics for different segments or regions of the 3-D model, which may include hiding certain segments or making certain segments semi-transparent. With such a system, the view of the 3-D model provided by the virtual camera view may be modified to remove or deemphasize less relevant segments, to display or emphasize more relevant segments (e.g., critical patient anatomy), or both.

  • Patent number: 11116420
    Abstract: Physicians performing invasive procedures utilize instruments inserted into a human body to perform the procedures. Such procedures typically involve actions to be performed on specific targeted anatomical structures. During the procedure, nearby anatomical structures unrelated to the procedure should generally be avoided. A system and techniques are provided herein for monitoring the position of such unrelated nearby anatomical structures relative to one or more surgical instruments. The system emits a warning to a human operator such as a surgeon if one of the instruments is too close to a monitored anatomical structure.

  • Patent number: 11058497
    Abstract: Physicians performing invasive procedures require accuracy and precision when working with surgical tools. Surgical procedures are increasingly becoming minimally invasive, with physicians operating using cameras to view the surgery site and directing their tools through oculars or video displays. Ideally, the physician should be able to perform the invasive procedure while simultaneously observing both the real-time image of the patient and additional data critical for his medical decisions about the manipulation of the surgical tool and the next surgical step. The augmented reality navigation system of the present disclosure provides tool location visibility for invasive procedures through the use of location sensors included on a camera and/or on the tools used during a procedure. A location tracking system determines and monitors the locations of the tools and camera based on the characteristics of signals detected by the sensors and displays informational overlays on images obtained with a camera.

  • Publication number: 20210169549
    Abstract: A method of ablating tissue of a target anatomical structure in an ear, a nose, or a throat of a patient includes inserting a balloon catheter into the ear, the nose, or the throat. The distal end of the balloon catheter is advanced distally until the balloon is disposed in the target anatomical structure. The balloon is inflated to an expanded configuration in the target anatomical structure. The tissue is ablated using at least one of photodynamic therapy or heated inflation fluid within the balloon. For photodynamic therapy, a photosensitizer is exposed to a light to produce a form of oxygen to ablate the target anatomical structure when the balloon is in the expanded configuration. For heated inflation fluid, heat is applied by a heating element to heat the inflation fluid in the balloon and thereby ablate the target anatomical structure when the balloon is in the expanded configuration.

  • Publication number: 20210121238
    Abstract: A visualization system may be implemented with an image guided surgery navigation system for use during ENT procedures. Correlated datasets such as surgical paths and pre-operative image slices may be correlated with the coordinate system of the navigation system for reference during a procedure. A surgeon may wear a head mounted display (“HMD”) having a transparent screen through which the patient anatomy may be viewed. The orientation and distance of the head mounted display relative to the patient anatomy may be determined using magnetic position tracking, image analysis of images captured by a camera of the HMD, or both. Correlated datasets may then be transformed based on the relative distance and orientation and may be displayed via the transparent screen to overlay directly viewed patient anatomy. Some implementations may include optical fiducials integrated with a patient tracking assembly to aid in tracking the patient and determining perspective of the HMD.

  • Publication number: 20210106390
    Abstract: An array of sensors may be used to perform touchless registration of landmarks of a patient's face before an ENT procedure in order to associate those landmarks with pre-operative images in three-dimensional space, which is required for image guided surgery features such as navigation. Touchless or light-touch registration may improve accuracy by avoiding the need for substantial pressing against a patient's skin, which may deform and thereby introduce erroneous registration data. A sensor may also be implemented in forms other than an array such as handheld probe having a single sensor as opposed to an array.
