  • Publication number: 20200201022
    Abstract: An endoscopic camera has two or more cameras positioned at a distal end, positioned to provide partially overlapping fields of view. The cameras communicate captured digital images the length of the flexible endoscope, where they may be saved and processed to provide additional imaging features. With partially overlapping images from two or more cameras, image processing can provide panoramic images, super resolution images, and three-dimensional images. One or more of these image modes may also be enhanced to provide a virtualization window that displays a portion of a larger or higher resolution image. The virtualization window displays the selected area of the image, and may be moved or zoomed around the image to provide a virtual endoscope repositioning experience, where the endoscope remains statically positioned but the virtualization window presents a sense of movement and navigation around the surgical area.

  • Publication number: 20200193600
    Abstract: A set of pre-operative images may be captured of an anatomical structure using an endoscopic camera. Each captured image is associated with a position and orientation of the camera at the moment of capture using image guided surgery (IGS) techniques. This image data and position data may be used to create a navigation map of captured images. During a surgical procedure on the anatomical structure, a real-time endoscopic view may be captured and displayed to a surgeon. The IGS navigation system may determine the position and orientation of the real-time image; and select an appropriate pre-operative image from the navigation map to display to the surgeon in addition to the real-time image.

  • Publication number: 20200187924
    Abstract: An apparatus includes an occlusion device operable to fit securely in an anatomical passageway within a head of a human. The occlusion device is configured to move unitarily with the head when the occlusion device is installed in the anatomical passageway. The occlusion device is further configured to prevent passage of fluid through the anatomical passageway when the occlusion device is installed in the anatomical passageway. A position sensor is fixedly integrated into the occlusion device. The position sensor generates signals indicating a position of the occlusion device in three-dimensional space, thereby indicating the position of the head in three-dimensional space. A connector communicatively coupled to the position sensor is operable to receive and transmit the signals generated by the position sensor.

  • Publication number: 20200108236
    Abstract: An apparatus may be used with an elongate member that includes an engagement member, a hollow shaft, a compression member, a compression element, and a resilient gripping member. The hollow shaft extends from the engagement member along a longitudinal axis. The compression member is slidably disposed over the hollow shaft. The hollow shaft is disposed over the resilient gripping member and supports the compression element. The compression member has a conical inner surface including a detent feature. The conical inner surface is configured to urge the compression element radially inwards as the collar advances from the unlocked position toward the locked position where the detent feature retains the compression element. The compression element deforms the resilient gripping member radially inwards to grip the elongate member and prevents translation of the elongate member. When unlocked, the resilient gripping member moves radially away from the elongate member allowing translation.

  • Publication number: 20190388157
    Abstract: A physician preparing to perform a surgical procedure may view pre-operative images of a procedure area of a patient and use a stylus or other interface to draw boundaries between or around areas shown in the images that should be treated with extreme caution during the procedure. These boundaries may be provided by an image guided surgery navigation system and used to provide warnings (e.g., audible or visual alerts having characteristics associated with the proximity to the bounded area) and control operations of a medical instrument (e.g., reducing a cutting speed or disabling the medical instrument entirely) during the procedure in order to reduce risks associated with using the medical instrument in or around the bounded areas. Other safety features that may be defined or pre-configured based on the procedure include reacting to movement patterns (e.g., high linear speed) and location patterns (e.g., steady advancement towards an unsafe area).

  • Publication number: 20190201016
    Abstract: Variations of integral navigation controls may be used in conjunction with a medical instrument to provide navigation functions for an image guided surgery (IGS) system that is in communication with the integral navigation controls. In some variations, a medical instrument with integrated navigation wheels allows movement of a cursor of the IGS system along the x and y axis by scrolling the wheel, or allows selection, zooming, or other controls by combined clicking and/or scrolling of wheels, and may be sterilized or discarded along with the device. In some other variations, a control overlay may be temporarily attached to the medical instrument to provide additional controls, such as buttons or a pointing stick, and then removed and sterilized or discarded after a procedure. In each variation, inputs may be communicated via wire or wirelessly to an IGS system to provide navigation of images during a surgical procedure.
