  • Patent number: 10932866
    Abstract: A method for removing an implant attached to a bone during revision joint replacement surgery includes a library of implant models. A series of surface points are collected on the implant with a digitizer. A best match is computed between the collected surface points and an implant model in the library of implant models to register the position of the implant model to the implant. A location is computed of a material-implant interface based on the geometry of the implant model and the registered position of the implant model. Material is removed at the material-implant interface to separate the implant from the bone. A computer-assisted surgical system is provided for performing the method.

  • Patent number: 10905438
    Abstract: Described herein are examples of orthopedic drill bits and methods of preparing a bone of a living being for fixation. An example method includes coupling a drive attachment of a drill bit to a mounting attachment of a driver, and placing a guide at a desired location on the bone. The guide has an opening corresponding to an area of bone to be removed. The guide provides proper positioning and alignment for drilling a hole. With the guide in place, the method further includes aligning the drill bit with the opening on the guide and drilling a hole in the bone. Once the hole is drilled, the method includes de-coupling the drill bit from the driver, and bending the drill bit at the drive attachment while the drill bit is still in the bone. In some examples, additional method steps follow preparation of the hole.

  • Patent number: 10881524
    Abstract: The embodiments provide various interbody fusion spacers, or cages, for insertion between adjacent vertebrae. The cages may have integrated ratchet assemblies that allow the cage to change size and angle as needed, with little effort. The cages may have a first, insertion configuration characterized by a reduced size to facilitate insertion through a narrow access passage and into the intervertebral space. The cages may be inserted in a first, reduced size and then expanded to a second, larger size once implanted. In their second configuration, the cages are able to maintain the proper disc height and stabilize the spine by restoring sagittal balance and alignment. Additionally, the intervertebral cages are configured to be able to adjust the angle of lordosis, and can accommodate larger lordotic angles in their second, expanded configuration. Further, these cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

  • Patent number: 10857001
    Abstract: A bone graft loading system includes a loading funnel, syringe, cannula, plunger, and loading tool. The loading funnel includes an interior passageway to receive the cannula and a syringe docking portion. The syringe may be coupled to the syringe docking portion so that it extends along a longitudinal axis that is transverse to the longitudinal axes of the cannula and the loading funnel. A user may advance bone graft from the syringe to a holding area of the loading funnel. The user may then move the loading tool through the holding area and into the interior space of the cannula to load the cannula with bone graft. This process may be repeated until the cannula is fully loaded with bone graft. The cannula and the plunger inside the cannula may then be removed from the loading funnel and coupled to an injector assembly for use in surgery.
