  • Patent number: 10231607
    Abstract: A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

  • Publication number: 20190053700
    Abstract: A medical apparatus is described for providing visualization of a surgical site. The medical apparatus includes an electronic display disposed within a display housing, the electronic display configured to produce a two-dimensional image. The medical apparatus includes a display optical system disposed within the display housing, the display optical system comprising a plurality of lens elements disposed along an optical path. The display optical system is configured to receive the two-dimensional image from the electronic display, produce a beam with a cross-section that remains substantially constant along the optical path, and produce a collimated beam exiting the opening in the display housing. The medical apparatus can also include an auxiliary video camera configured to provide an oblique view of a patient on the electronic display without requiring a surgeon to adjust their viewing angle through oculars viewing the electronic display.

  • Publication number: 20180368656
    Abstract: A surgical visualization system can provide visualization of a surgical site. The surgical visualization system can include a first support having a first movable arm, a second support having a second movable arm, and a viewing platform mounted to a distal end of the first movable arm. The viewing platform can be configured to display images for viewing by a user at the viewing platform. The system can also include a camera mounted to a distal end of the second movable arm. The camera can be configured to provide a surgical microscope view of a surgical site that can be viewed by the user at the viewing platform. The system can also include a control system having electronics configured to receive input from the user to move the second movable arm so as to adjust the position and/or orientation of the camera in response to the input from the user.

  • Publication number: 20180318033
    Abstract: A light source includes features configured to compensate for discontinuous solid state sources. The light source can produce a wide color gamut in display, and improved color rendering of tissue under observation by phosphor gap filling with colored LEDs. The light source can include provisions to depart from a white light spectrum to heighten differences in anatomical features or functions. The light source can include provisions to introduce narrow-band solid-state sources for producing false-color and pseudo-color images, with variable color rendering to change the power spectral distribution and to compensate for fiber optic length and fiber optic diameter tip sensing.
