  • Publication number: 20210236212
    Abstract: An optical tracker usable with a surgical object, the optical tracker includes a tracker frame including a mounting body, which defines an instrument engaging aperture having a longitudinal axis, and an offset body protruding proximally from the mounting body. The instrument engaging aperture is configured to receive a proximal region of the surgical instrument such that the longitudinal axis of the tracker is aligned with an axis of the surgical instrument. The tracker may further include a tracking array coupled to the tracker frame and comprising a mounting fixture and a plurality of LED emitters coupled thereto. The optical tracker may further comprise at least three apex points defined by the tracker frame that extend to a height above the LED emitters.

  • Patent number: 11045259
    Abstract: A surgical navigation system is provided. The surgical navigation system comprises a camera system comprising at least one camera. The camera system is capable of capturing images of light that is filtered through at least three different polarization angles. The surgical navigation system further comprises a processor having access to three dimensional image data of a surgical object. The processor is configured to determine first surface normals from the three dimensional image data of the surgical object. The processor is further configured to determine second surface normals from at least three images captured by the camera system of the surgical object under different polarization angles. The processor is configured to align the first surface normals with the second surface normals. Furthermore, a method for operating a surgical navigation system is provided.

  • Publication number: 20200072270
    Abstract: A connecting member includes a fastening portion configured to be fastened to an object by an adhesive. The connecting member includes at least one supply opening for supplying the adhesive and at least one discharge opening for discharging a part of the adhesive, wherein the at least one supply opening and the at least one discharge opening are arranged outside of a fastening portion or at least outside of a fastening area. A channel connecting the at least one supply opening and the at least one discharge opening is configured to direct the flow of adhesive. The channel includes an open channel portion that at least partly extends on a surface of the fastening portion and that comprises at least one redirecting portion configured to redirect the flow of adhesive between the at least one supply opening and the at least one discharge opening.
