DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, a combined reconstruction bone plate includes a reconstruction plate 1, a connecting plate 2 and a connecting screw 3. The reconstruction plate 1 is provided with a screw hole, and at least one end of the connecting plate 2 is provided with a connecting head 21, and the connecting head 21 is provided with a connecting hole 22; the connecting screw 3 can be assembled in the connecting hole 22 and connected to any screw hole on the reconstruction plate 1.

[0030] In order to facilitate shaping of the reconstruction plate 1 and ensure fit with the bone surface, the reconstruction plate 1 includes cylindrical platforms arranged in a straight line, and two adjacent cylindrical platforms are connected by a reconstruction belt.

[0031] Specifically, the reconstruction plate 1 includes a cylindrical platform Ⅰ11 and a reconstruction belt Ⅰ12.

[0032] In order to facilitate shaping of the connecting plate 2 and ensure fit with the bone surface, the connecting plate 2 includes cylindrical platforms arranged in a straight line, and two adjacent cylindrical platforms are connected by a reconstruction band.

[0033] Specifically, the connecting plate 2 includes a cylindrical platform II 23 and a reconstruction belt II 24 .

[0034] In order to connect the connector 21 to the reconstruction plate 1 on the basis of making the cylindrical platform II 23 flush with the reconstruction plate 1 , the connector 21 is bent upward and is not in the same plane as the cylindrical platform.

[0035] In order to ensure the fixing strength at the screw hole, a screw hole coaxially arranged therewith is opened on the cylindrical platform.

[0036] Specifically, at least two cylindrical platforms Ⅰ11 are provided on the reconstruction plate 1, and correspondingly at least two screw holes Ⅰ13 are provided, wherein one screw hole Ⅰ13 is used to assemble the connecting plate 2, and the other screw hole Ⅰ13 can be used to install a bone screw to fix the fracture.

[0037] The screw holes II25 on the cylindrical platform II23 of the connecting plate 2 can also be used to install bone screws to fix the fracture.

[0038] The structure of the connecting plate 2 specifically includes the following two categories:

[0039] Category 1: The connecting plate 2 is not provided with a cylindrical platform II 23 and a reconstruction belt II 24, but only has two connectors 21. In this case, the two connectors 21 are directly connected and are flat plate structures, with both ends capable of connecting to the reconstruction plate 1.

[0040] The second type: The connecting plate 2 includes one or two connecting heads 21 and at least one cylindrical platform II 23. The connecting head 21 is used to connect to the screw hole I 13 on the reconstruction plate 1, and the screw hole II 25 on the cylindrical platform II 23 can be installed with bone screws to fix the fracture position; the connecting head 21 is bent upward based on the plane where the cylindrical platform II 23 is located.

[0041] When there is only one cylindrical platform II 23 , no reconstruction belt II 24 is provided on the connecting plate 2 . If there are at least two cylindrical platforms II 23 , two adjacent cylindrical platforms II 23 are connected via the reconstruction belt II 24 .

[0042] The connection plate 2 disclosed in this embodiment is the second type.

[0043] In order to facilitate the installation of the bone screw or the connecting screw 3, the upper section of the screw hole is a spherical countersunk hole, and the lower section is a straight threaded hole.

[0044] To facilitate shaping, the reconstruction band is a cylindrical structure.

[0045] The cylindrical reconstruction band can be shaped in various directions according to the desired shape.

[0046] In order to hide the connecting screw 3 , the connecting hole 22 is a spherical countersunk hole.

[0047] In order to ensure the fit with the upper surface of the reconstruction plate 1 , the lower surface of the connector 21 is an inwardly concave arc structure.

[0048] After the connector 21 is installed on any screw hole of any reconstruction plate 1 , in order to ensure the stability of the connection, the lower surface of the connector 21 is provided with protrusions (not shown) located outside the connection hole 22 and arranged in a cross shape.

[0049] The cross-arranged protrusions can be tightly pressed against the surface of the reconstruction plate 1 when connected to the reconstruction plate 1 to resist rotation.

[0050] The protrusions are not limited to the above-mentioned cross arrangement, but may also be arranged in other ways.

[0051] In order to cooperate with the screw hole and the connecting hole 22 , the connecting screw 3 includes a screw head 31 with a hemispherical head structure and a screw rod 32 with a straight thread on the outer surface.

[0052] According to the fracture type, the reconstruction plate 1 is first used to fix the fracture ends, and then the reconstruction plate 1 and the connecting plate 2 are combined using the connecting screws 3. The combination form can be but is not limited to T-shaped, H-shaped, triangular, quadrilateral, stepped, etc.

[0053] The connection holes 22 on the connection plate 2 can be connected and matched with any screw holes on the reconstruction plate 1 without being restricted by the position, and various branch structures or frame structures can be formed by combination.

[0054] In addition, since the screw holes II 25 on the connecting plate 2 and the screw holes I 13 on the reconstruction plate 1 have the same structure, when a combined bone fracture plate includes more than one connecting plate 2, the connecting head 21 of one connecting plate 2 can be connected to the screw hole I 13 on the reconstruction plate 1 as well as to the screw hole II 25 on another connecting plate 2, thereby achieving a combined method to achieve stable fixation of the fracture site.

[0055] The present invention can solve various types of fracture problems by combining the reconstruction plate 1 with the connection plate 2 and has good versatility.

[0056] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
