  • DETAILED DESCRIPTION OF THE INVENTION
  • Detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely illustrative of the invention that may be embodied in various forms. In addition, each of the examples given in connection with the various embodiments of the invention are intended to be illustrative, and not restrictive. Further, the figures are not necessarily to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
  • Referring now to FIG. 1 (as well as FIGS. 2A and 2B, showing exploded perspective views of the bone plate apparatus of FIG. 1), one embodiment of a bone plate apparatus according to the present invention is shown. As seen in these Figs., Bone Plate 101 may be attached to bone using Bone Screws 103 a, 103 b and 103 c. In one example (which example is intended to be illustrative and not restrictive), Bone Plate 101 may have a length between 20 mm and 30 mm (e.g., Bone Plate 101 may be provided in a number of distinct lengths). In another example (which example is intended to be illustrative and not restrictive), each of Bone Screws 103 a, 103 b and 103 c may be a self-tapping bone screw. In another example (which example is intended to be illustrative and not restrictive), each of Bone Screws 103 a, 103 b and 103 c may have a diameter selected from the group including (but not limited to) 1.5 mm, 2.0 mm and 2.7 mm. In another example (which example is intended to be illustrative and not restrictive), each of Bone Screws 103 a, 103 b and 103 c may have a length from 4 mm to 8 mm, in 0.1 mm increments.
  • Further, Locking Plate 105 (which may itself be held in place by Fastener 107 (e.g., a machine screw)) may be used to help prevent screw back-out (FIGS. 2A and 2B show use of Locking Plate 105 and Fastener 107 most clearly).
  • Further still, Slot 109 (which may have distinct holding positions or detents (as shown in these Figs.), and/or which may not have such detents in order to allow essentially free positioning anywhere within the slot) may be provided to aid in adjustment to an individual patient's anatomy.
  • Further still, one or more protrusions (or “teeth”) may be provided to aid in maintaining position during and/or after implantation (a number of such teeth are shown but not separately numbered in these Figs.).
  • Further still, the bottom profile may be streamlined as shown in these Figs. (e.g., in order to reduce the penetration inside the spine).
  • Referring now to FIGS. 3A, 3B and 3C, a plan view, a side elevational view and a front view of the bone plate apparatus of FIG. 1 are shown. Of note, the dimensions identified in these Figs. are, of course, illustrative and not restrictive.
  • Referring now to FIGS. 4A, 4B and 4C, a plan view, a side elevational view and a front view of a bone plate apparatus according to an embodiment of the present invention are shown. Of note, these Figs. depict the bone plate apparatus without showing the bone screws. Of further note, the dimensions identified in these Figs. are, of course, illustrative and not restrictive.
  • Referring now to FIGS. 5A, 5B and 5C, a plan view, a side elevational view and a front view of a bone plate apparatus according to an embodiment of the present invention are shown. Of note, these Figs. depict the bone plate apparatus without showing the bone screws. Of further note, the dimensions identified in these Figs. are, of course, illustrative and not restrictive.
  • Referring now to one example use of a bone plate apparatus according to the present invention (which example is intended to be illustrative and not restrictive), it is noted that under this example an “open door laminoplasty” (wherein the vertebrae are made to swing open like a door) may be simplified and/or stability may be maintained (such simplification/stability may be obtained by replacing and/or supplementing certain steps and/or components of a conventional laminoplasty with steps and/or components of the present invention (e.g., with an embodiment of the bone plate apparatus described herein). Such an open door laminoplasty is typically performed on a restricted spinal canal in the neck (e.g., a painfully restricted spinal canal), wherein the laminoplasty relieves pressure (e.g., immediately) by creating additional space for the spinal cord and roots.
  • More particularly, such a laminoplasty is typically performed as follows:
      • The surgeon makes an incision on the back of the patient's neck.
      • The surgeon creates a “hinge” by cutting a groove down one side of the cervical vertebrae.
      • The surgeon cuts all the way through the other side of the vertebrae.
      • In order to create room for the bones to open like a door, the surgeon removes the tips of the spinal process.
      • In order to take pressure off the spinal cord and roots, the surgeon bends open the back of each vertebrae (like a door on its hinge).
      • The surgeon places, in the opened space of the door, appropriately sized wedges made of bone.
      • The surgeon allows the door to swing shut. Since the wedges stop the door from closing all of the way, the spinal cord and roots receive additional space.
  • Referring now to FIG. 6, it is seen that Insertion Tool 601 may be used to aid insertion into a patient (e.g., to make placement quick and easy), and that Insertion Tool 601 may include Handle 603, Shaft 605 and Mounting Mechanism 607 (which may be used to hold a bone plate and/or to aid in turning the various screws associated with the bone plate).
  • Referring now to FIG. 7, a cut-away view of a bone plate apparatus according to an embodiment of the present invention is shown. Of note, this Fig. clearly shows Detents 703 a, 703 b and 703 as well as Machine Screw Retaining Thread 705.
  • Referring now to FIG. 8, another perspective view of two bone plate apparatus according to embodiments of the present invention are shown.
  • In another embodiment, some or all of the components may include or be made essentially entirely from a commercially pure material (e.g., Titanium and/or Alloy Titanium).
  • In another embodiment, Indications relating to use of the present invention may include (but not be limited to):
      • For use as laminoplasty plate for cervical spine (from C2-C7)
      • For use as orthognathic plate for fixation (e.g., permanent fixation) of bone segment(s) after a sagittal split Osteotomy.
  • While a number of embodiments of the present invention have been described, it is understood that these embodiments are illustrative only, and not restrictive, and that many modifications may become apparent to those of ordinary skill in the art. For example, while the present invention has been described principally with respect to three bone screws, any desired number may, of course, be utilized. Further, the teeth, grooves and/or ridges may be placed at any desired position(s) on the bone plate apparatus. Further still, one or more slots may be utilized for one or more bone screws. Further still, any desired number of detents may be utilized. Further still, the angle between the portion of the bone plate shown principally with one bone screw and the portion of the bone plate shown principally with two bone screws may be any desired angle. Further still, any desired mechanism(s) for locking one or more bone screws relative to the bone plate may be utilized (instead of or in addition to the locking plate described above). Further still, the bone plate apparatus may, of course, have any desired dimensions (e.g., for any desired patient—man, woman or child). Further still, the bone plate apparatus of the present invention may be provided in a “line” or “family” of devices (e.g., small, medium and large; adult, child; male, female). Further still, the bone plate apparatus of the present invention may be provided in standard sizes. Further still, one or more components may be constructed of Ti, cobalt chromium, surgical steel and/or any combination thereof. Further still, a “hole” may be of any desired shape (e.g., circular, square, oval, rectangular, etc.). Further still, any steps relating to manufacture and/or use may be performed in any desired order.
