DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027] Although some words has been used in the specification and subsequent claims to refer to particular components, person having ordinary skill in the art will appreciates that manufacturers may use different terms to refer to a component. The specification and claims are not to be differences in the names as a way to distinguish between the components, but with differences in the function of the component as a criterion to distinguish. As mentioned throughout the specification and claims, in which the include, has, comprise, and with are an open-ended term, they should be interpreted as including but not limited to.

[0028] One preferred embodiment discloses a surgery guiding bone plate 100, as shown in FIG. 1 and FIG. 2 which illustrate plan schematic diagrams of the surgery guiding bone plate 100, including a guiding bone plate 10, a first bone plate 11 and a second bone plate 12, wherein a guiding groove 13 is arranged between the first bone plate 11 and the second bone plate 12; furthermore, the surgery guiding bone plate 100 also includes a fixing and clamping device 20, which connects to the first bone plate 11 and the second bone plate 12, respectively.

[0029] As shown in FIG. 2, the surgery guiding bone plate 100 is installed with one or more locking sections 14 penetrating the first bone plate 11 and the second bone plate 12, wherein the locking sections 14 may be an opening. When an orthognathic surgery is performed, the locking sections 14 on the surgery guiding bone plate can be used as drilling positions on the upper and lower jaws and cheek bones, and then use bone nails to lock and fix the bone plate for adjustment. The guiding groove 13 arranged between the first bone plate 11 and the second bone plate 12, which may be a gap, is used for assisting and guiding the oral and maxillofacial surgeon and the orthodontist to find preset cutting locations when operating scalpels to cut open the upper/lower jaw and cheek bones, thereby avoiding errors in locating cut positions.

[0030] As shown in FIG. 3, the combined schematic diagram of a combined device illustrates a combination of the surgery guiding bone plate 100 and the flap opening-up instrument 30. The surgery guiding bone plate 100 includes a fixing and clamping device 20, wherein the fixing and clamping device 20 has a hook-like appearance. When the oral and maxillofacial surgeon and the orthodontist cut the upper/lower jaw and cheek bones, the fixing and clamping device 20 is used to clamp and secure the flap opening-up instrument 30, thereby preventing the flap opening-up instrument 30 from failing to secure during the surgery which results in bone shift in terms of finding preset positions, therefore, errors in locating cutting positions can be prevented.

[0031] As shown in FIG. 4, the 3D schematic diagram of the surgery guiding bone plate illustrates the surgery guiding bone plate 100 including a guiding bone plate 10 and a fixing and clamping device 20, which is connected to the first bone plate 11 and the second bone plate 12, respectively. The first bone plate 11 and the second bone plate 12 are in curved appearance, respectively, so that the first bone plate 11 and the second bone plate 12 can tightly join with the upper/lower jaw and cheek bones at preset locations. Moreover, the first bone plate 11 and the second bone plate 12 guide the oral and maxillofacial surgeon and the orthodontist to find preset cutting positions when operating scalpels to cut open the upper/lower jaw and cheek bones. The first bone plate 11 and the second bone plate 12 can use computing software of a custom graphical user interface (GUI) to calculate the change of angle with curvature and gradient. The computing software of a custom graphical user interface (GUI) can be of commercial products such as GRASSHOPPER to calculate axial positions of X, Y, Z and angles, furthermore, the first bone plate 11, the second bone plate 12 and the fixing and clamping device 20 can use laser metal additive technique to manufacture.

[0032] According to the embodiment, the guiding bone plate 10 may be made of medical titanium alloys (Ti-6AI-4V), and the fixing and clamping device 20 may be made of medical titanium alloys (Ti-6AI-4V) as well.

[0033] According to the embodiment, the first bone plate 11 and the second bone plate 12 may be both replaced by a plane bone plate, the guiding groove 13 may be replaced by an opening, the locking sections 14 may be replaced by a screw hole, the fixing and clamping device 20 may be replaced by a suspension loop, a hanging hook, a C-shaped hook, or an L-shaped hook, the guiding bone plate 10 may be replaced by bioabsorbable materials, the fixing and clamping device 20 may be replaced by bioabsorbable materials, and the guiding bone plate 10 and the fixing and clamping device 20 may be manufactured by 3D metal printing technique.

[0034] Another preferred embodiment as shown in FIG. 5, which is a plan schematic diagram of the surgery bone plate 100, illustrates that the surgery guiding bone plate 100 includes a guiding bone plate 10, a first bone plate 11 and a second bone plate 12, and a fixing and clamping device 20; wherein the first bone plate 11 and the second bone plate 12 has one or more locking sections 14, and the fixing and clamping device 20 connects to one side of the first bone plate 11 and the second bone plate 12, respectively. The first bone plate 11, the second bone plate 12 and the fixing and clamping device 20 are arranged with a guiding groove 13 therein, thereby enabling the oral and maxillofacial surgeon and the orthodontist to be guided to preset cutting positions when operating scalpels to cut open the upper/lower jaw and cheek bones through the guiding groove 13.

[0035] Another preferred embodiment as shown in FIG. 6 is a combined schematic diagram of the surgery guiding bone plate being used on a human. When an orthognathic surgery is performed, the original palatine bone is cut open, adjusted, and then re-joined by using bone plates and bone nails for shaping. As shown in FIG. 6, the surgery guiding bone plate 100 can be combined with the upper/lower jaw and cheek bones of a human skull 200. When the oral and maxillofacial surgeon and the orthodontist use scalpels to cut the upper/lower jaw and cheek bones at preset positions, the surgery guiding bone plate 100 can further precisely guide them to the drilling positions on the upper/lower jaw and cheek bones, thereby enabling them to use bone nails to secure bone plate onto preset positions.

[0036] There have thus been shown and described a surgery guiding bone plate. Many changes, modifications, variations and other uses and applications of the subject invention will, however, become apparent to those skilled in the art after considering this specification and the accompanying drawings which disclose the preferred embodiments thereof. All such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention.
