  • Publication number: 20240057854
    Abstract: A filter assembly is configured to optically couple a camera head to an endoscope. The filter assembly includes a first end adapted to be removably coupled to the camera head and a second end opposite and spaced apart from the first end, the second end adapted to be removably coupled to the endoscope. The filter assembly includes an optic housing disposed between the first end and the second end, the optic housing includes an optical path length maximizer and a first window. The first window has a first surface that is angled with respect to a plane that is perpendicular to a longitudinal axis of the optic housing so as to minimize a narcissus reflection within the optic housing and an optical filter to reject laser irradiation.

  • Patent number: 11892617
    Abstract: The present invention relates to a method for producing adaptive lighting controls for an endoscope with multiple light emitting elements such as distinct light fibers, or distinct distal light emitting diodes (LEDs), etc. The amount of light delivered to the scene can be locally adjusted on a per-light basis to manage the dynamic range of the scene. For example highly reflective metallic tools many benefit from reduced light, while cavities may benefit from increased light projected into the lumen.

  • Patent number: 11877720
    Abstract: A fluorescence imaging system is configured to generate a video image onto a display. The system includes a light source for emitting infrared light and white light, an infrared image sensor for capturing infrared image data, and a white light image sensor for capturing white light image data. Data processing hardware performs operations that include filtering the infrared image data with a first digital finite impulse response (FIR) filter configured to produce a magnitude response of zero at a horizontal Nyquist frequency and a vertical Nyquist frequency. The operations also include filtering the infrared image data with a second digital FIR filter configured with a phase response to spatially align the white light image data with the infrared image data. The operations also include combining the white light image data and the infrared image data into combined image data and transmitting the combined image data to the display.

  • Publication number: 20230389777
    Abstract: An endoscope includes a distal tip with a sterile cap disposed on the distal tip. The sterile cap reduces the exposure of the distal tip to contamination and includes an integrating sphere that enables calibration of an image sensor disposed in the endoscope. By enabling calibration of the image sensor while the sterile cap remains on the distal tip of the endoscope, the image sensor can be calibrated while maintaining the sterility of the endoscope. The sterile cap can be disposed on the distal tip of the endoscope under sterile conditions, placed in a sterile packaging, and can be removed just before a medical procedure to reduce the risk of exposing the endoscope to contamination.

  • Patent number: 11783942
    Abstract: Systems, devices, methods, and program products are provided for operating a medical system that is operable within at least two different medical device regulatory classes. A device control module receives an indicator for performing at least one procedure with a medical device. Based on the indicator, it selects a binary image for booting the control module from among multiple images including a controlled-type and a non-controlled type, which operate in different regulatory classes. A controlled-type image, which may be FDA PMA or other regulatory classes, is verified to be unaltered, and is then used to operate as a regulated medical device. The indicator can be automatic or manual. The indicator may result from connection of a specific medical device or peripheral device or may be user input.

  • Publication number: 20230301499
    Abstract: Improved fluoresced imaging (FI) endoscope devices and systems are provided to enhance use of endoscopes with FI and visible light capabilities. An endoscope device is provided for endoscopy imaging in a white light and a fluoresced light mode. A chromatic adjustment assembly, typically implemented with prisms, compensates for a chromatic focal difference between the white light image and the fluoresced light image caused by the dispersive properties of the optical materials or optical design employed in the construction of the optical channel. The assembly is placed optically between the most proximal rod lens of the endoscope and the focusing optics, typically at an internal telecentric image space, to improve the chromatic correction. The prism assembly directs incoming light with different spectral content along separate paths which compensate for chromatic aberration.

  • Patent number: 11730340
    Abstract: The present disclosure is directed towards a video display system and an endoscopic system configured to provide the surgeon with an optimized video image based upon user preference. The video display system includes a first video image displaying a white light video of a surgical site. The first video image has a first predetermined area. A second video image is overlaid on the first video image. The second video image is displayed in a fluorescent light video. The second video image is centered on the surgical site and includes a second predetermined area. The second predetermined area is smaller than the first predetermined area so as to define a boundary of white light video. Thus, the video display system provides the surgeon with the ability to reference the location of the fluorescent light video with respect to anatomical features of the surgical site.

  • Publication number: 20230217118
    Abstract: Methods and systems are provided to generate metamerically matched illumination on a surgical site. The metamerically matched illumination may reduce or remove strobing effects associated with illumination devices during a surgery or surgical procedure. By metamerically matching illuminants in the illumination in combination with estimates of the human visual system, the illumination of the surgical site can visually appear to a user as a continuous white light, while maintaining distinct underlying spectra in the illumination. The light reflected by the surgical object may also be captured and metamerically matched, such that the reflected light appears as a single continuous color.
