  • Patent number: 11857377
    Abstract: An ingress-egress apparatus for protection of a surgical work site during removal of a surgical implant therefrom includes an inverted frustum surface having a sidewall defining: a bottom open area at a base portion of the frustum surface sidewall, and an opposing top open area at a top portion of the frustum surface sidewall. The top open area has a larger area than the bottom open area. The apparatus includes an ingress port located at the base portion of the frustum surface sidewall and an egress port located at the base portion of the frustum surface sidewall. During surgical removal of the surgical implant using a surgical burr, the apparatus can be used to irrigate the work site, thereby cooling it and protecting it from damage, and further removing metal implant particles generated during burring.

  • Patent number: 11534210
    Abstract: The disclosure relates to a surgical system and related methods to facilitate reduction and fixation of sacro-iliac luxations/fractures (SIL/F) in small animals, for example dogs and cats. In another aspect, the disclosure relates to an aiming device and related methods providing accurate, reliable, and safe fixation of SIL/F in such small animals. The surgical system includes a work surface, an articulatable and lockable reduction arm mounted to the work surface, a reduction handle mounted to the reduction arm; an articulatable and lockable fixation arm mounted to the work surface, a fixation drill guide mounted to the fixation arm, and an image acquisition unit directed toward the work surface. The surgical system provides enhanced safety to surgical personnel using the system in terms of reduced exposure to harmful radiation form the image acquisition unit.

  • Patent number: 9072553
    Abstract: The present invention demonstrates and improved interlocking nail and screw combination to repair fracture bones. The preferred combination uses an hourglass shaped intramedullary nail wherein the larger ends of the nail have holes capable of receiving screws. The holes may, or may not be conical. Further, the holes may or may not be threaded. The surgical screws have a variety of thread patterns, or lack threads. A non-threaded end is believed to improve healing because of a larger core diameter as compared to a comparably sized threaded screw end.
