  • Patent number: 8352056
    Abstract: The present invention illustrates a method of manufacturing a surgical implant guide to increase the precision, safety and reliability of the surgery. First the present invention plans an invasive position for implanting an implant, and then, plans an invasive path for the implant to invade from the invasive position of an affected tissue, and finally, produces an implant guide based on the invasive position, the invasive path, and the shapes of the implant and the affected tissue. The surgical implant guide includes a coupling portion matching the shape the affected tissue, and a guiding portion matching the shape of the implant, the invasive position, and the invasive path. When the coupling portion is disposed on the affected tissue, the guiding portion is aligned with the invasive position, so that the implant is implanted in the affected tissue under guidance of the invasive path.

  • Patent number: 8106941
    Abstract: The present invention discloses a stereoscopic display apparatus comprising a first and a second image displayer, an aspherical reflection mirror, a beamsplitter and a housing. The first and the second image displayer are used for projecting a first and a second image light respectively. The aspherical reflection mirror is used for refracting the image light and for changing a polarity of the image light. The beamsplitter, disposed between the image generator and the aspherical reflection mirror, is used for deflecting a proceeding route of the image light based on the polarity of the optical signal. The housing has at least one opening for an operator to inspect a first image and a second image through.

  • Publication number: 20100042164
    Abstract: The invention provides an expansion screw set, a hollow nail and an interior nail. The expansion screw set is composed of the hollow nail and the interior nail. The hollow nail has a hollow structure. A first thread and a second thread are provided for the inside and the outside of the hollow nail. The interior nail has a third thread. The hollow nail could nail an object through the first thread. The third thread of the interior nail corresponds to the second thread of the hollow nail. Therefore, the interior nail can be fastened into the hollow structure after the interior nail is nailed into the hollow nail. Moreover, the hollow nail has a separation line which runs parallel to the penetration direction of the hollow structure. Alternatively, the hollow nail has a plurality of penetration holes which is vertical to the penetration direction of the hollow structure. After the interior nail is nailed into the hollow structure, the separation line can be stretched out through the interior nail.
