  • Publication number: 20190038414
    Abstract: A maxillofacial orthognathic fixation implant assembly and its method of production and use, the implant being an assembly of an upper anchor implant member, a lower anchor implant member and at least one bridging implant member, the anchor implant members being adapted to be securely mounted to a maxilla and the at least one bridging implant member being adapted to connect the upper anchor implant member to the lower anchor implant member in a fixed and rigid manner. With the anchor implant members affixed to the maxilla and the maxilla surgically separated between the upper and lower anchor implant members to create a lower portion detached an upper portion, the at least one bridging implant member is connected between the upper and lower anchor implant members to secure and maintain the lower portion of the maxilla in a desired post-operative position relative to the upper portion of the maxilla.

  • Publication number: 20180338784
    Abstract: A bone plate locking cannula and drill guide assembly having a locking cannula detachably mountable onto screw-receiving apertures of a bone plate and a drill guide received within the locking cannula such that pilot holes are drilled through the apertures into bone at the proper angle to receive bone screws. The screw receiving apertures have a proximal bore of greater diameter than a distal bore, and the proximal bore is provided with internal threading to mate with external threading located on the distal end of the locking cannula. The bone screws are inserted through the locking cannula after removal of the drill guide and fastened into the bone to secure the bone plate in position without having to remove the locking cannulas from the bone plate, the internal diameter of the locking cannula bore being greater than the maximum diameter of the screw heads. The locking cannula is detached from the bone plate after the bone plate has been secured in place on the bone.

  • Publication number: 20180221069
    Abstract: A maxillomandibular fixation (MMF) device having an arch bar with a plurality of spaced tabs and gaps, and further having apertured mounting plate members mounted onto the arch bar, each mounting plate member having a slot to receive a tab on the arch bar, whereby the mounting plate members may be repositioned laterally along the arch bar from one tab to another prior to affixing the MMF device to the maxilla or mandible of a patient in order to position the mounting plate members at locations where the underlying tooth root will not be damaged by insertion of a bone screw.

  • Publication number: 20180116700
    Abstract: One or more arrays of flexible, disposable, bone plate sizers with corresponding arrays of permanent bone plates, systems using these bone plate sizers and/or templates, and methodologies using these bone plate sizers and/or templates are embodied. Each array of disposable bone plate sizers has a plurality of sizers having differing configurations and sizes, each of the disposable sizers in a given array corresponding to a particular bone screw size. Each of the disposable bone plate sizers in a given array are mounted upon and easily detachable from a frame member. The disposable bone plate sizers may be malleable such that may be manipulated by the surgeon into the desired three-dimensional shape to match the contour of the bone segments to be joined, thereby providing a template to shape the corresponding permanent bone plate.

  • Publication number: 20180092663
    Abstract: A force adjustable spring distractor device having an elongated, relatively thin guide plate, a force adjusting rod member having first and second oppositely threaded portions, first and second anchor bodies mounted on the guide plate and the threaded portions of the rod, first and second distractor bodies mounted on the guide plate and the rod, and first and second distraction springs connecting the anchor bodies to the distractor bodies, whereby rotation of the force adjusting rod results in separation of the anchor bodies and elongation of the distraction springs, thereby imparting a separation force to the distractor bodies.

  • Patent number: 9750537
    Abstract: A pair of bone plates adapted for attachment to cranial bone segments, the cranial plates being mounted to a distraction mechanism such that the cranial plates can be separated gradually in very small increments. Each of the cranial plates is mounted to the distraction mechanism with a ball and socket connector assembly, such that each of the plates can move in multiple directions and orientations relative to the distraction mechanism to better accommodate a convex, planar or concave surface topography presented during the distraction procedure.

  • Patent number: 7771434
    Abstract: An improved distractor apparatus of the type having at least a pair of opposing bone plates secured distally and proximally to a pair of bone segments created by cutting an osteotomy gap, wherein the mounting brackets for securing the bone plates to the distractor means comprise abutment members that extend into the gap and abut the exposed ends of the two bone segments, such that distraction force is transferred to the bone segments by both the bone plates and the abutment members, wherein at least the abutment member on the distal mounting bracket is collapsible in the distal direction.

  • Patent number: 7686836
    Abstract: A bone distractor having four bone plate attachment members for affixation to the posterior and anterior maxilla and/or zygomatic buttress and to the posterior and anterior mandible, the attachment members mounted onto a pair of parallel rods, one rod being a threaded drive rod and the other being a releasable guide rod, whereby rotation of the drive rod causes dimensional separation of the anterior attachment members from the posterior attachment members. The guide rod can be quickly removed such the superior attachment members joined to the maxilla and/or zygomatic buttress are physically separated from the inferior attachment members joined to the mandible such that the jaw can be opened.
