All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1-5, a combined reconstruction bone fracture plate comprises a reconstruction plate 1, a connecting plate 2 and connecting screws 3, wherein the reconstruction plate 1 is provided with screw holes, at least one end of the connecting plate 2 is provided with a connecting head 21, and the connecting head 21 is provided with connecting holes 22; the attachment screws 3 can fit into the attachment holes 22 and attach to any screw holes on the reconstruction plate 1.

In order to conveniently shape the reconstruction plate 1 and ensure the fitting degree with the bone surface, the reconstruction plate 1 comprises cylindrical platforms which are arranged in a straight line, and two adjacent cylindrical platforms are connected through a reconstruction belt.

Specifically, the reconstruction plate 1 includes a cylindrical platform i 11 and a reconstruction zone i 12.

In order to facilitate moulding connecting plate 2, guarantee with the laminating degree of bone surface, connecting plate 2 is including being the cylinder platform of sharp arrangement, and links to each other through rebuilding the area between two adjacent cylinder platforms.

Specifically, the connecting plate 2 comprises a cylindrical platform II 23 and a reconstruction band II 24.

In order to realize the connection between the connector 21 and the reconstruction plate 1 on the basis that the cylindrical platform II 23 is flush with the reconstruction plate 1, the connector 21 is bent upwards and is not in the same plane with the cylindrical platform.

In order to ensure the fixing strength of the screw hole, the cylindrical platform is provided with a screw hole which is coaxial with the cylindrical platform.

Specifically, at least two cylindrical platforms I11 are arranged on the reconstruction plate 1, and correspondingly at least two screw holes I13 are arranged, wherein one screw hole I13 is used for assembling the connecting plate 2, and the other screw hole I13 can be used for installing a bone screw to fix the fracture.

The screw holes II 25 on the cylindrical platform II 23 of the connecting plate 2 can also be used for installing bone screws to fix the fracture.

The structure of the connecting plate 2 specifically includes the following two types:

the first type: the connecting plate 2 is not provided with a cylindrical platform II 23 and a reconstruction belt II 24, only two connectors 21 are provided, the two connectors 21 are directly connected at the moment and are of a flat plate structure, and two ends of the connecting plate can be respectively connected with the reconstruction plate 1;

the second type: the connecting plate 2 comprises one or two connectors 21 and at least one cylindrical platform II 23, the connectors 21 are used for being connected with screw holes I13 on the reconstruction plate 1, and screw screws can be mounted on screw holes II 25 on the cylindrical platform II 23 to fix the fracture position; the connecting head 21 is bent upwards on the basis of the plane of the cylindrical platform II 23.
