The magnesium alloy has good biocompatibility, does not generate immunological rejection reaction, and has the effect of promoting the growth of bones. However, the magnesium alloy has low strength and poor mechanical property, and cannot be used alone as an orthopedic implant, so that the magnesium alloy is matched with the second base layer 102 by using the second base layer 102 with high strength as a substrate, so that the orthopedic implant has sufficient strength. In addition, the first base layer 102 is directly contacted with the skeleton, so that the magnesium alloy layer can better play a role in promoting the growth of the skeleton.
The first base layer 101 and the second base layer 102 have two specific mating forms as follows.
Example 1
In some embodiments of the invention, the first substrate is attached 101 to the second substrate 102. Specifically, the magnesium alloy can be made into magnesium alloy thin paper, which is similar to tin foil paper, cut into a required size and shape, and attached to the surface of the second base layer 102. The first base layer 101 does not necessarily cover the entire end surface of the second base layer 102, and the first base layer 101 may cover a part of one side end surface of the second base layer 102 as long as a contact area with the bone can be satisfied.
The effect of promoting bone growth of the orthopedic implant can be achieved by constructing only one layer of the magnesium alloy structure without designing the magnesium alloy layer to be of a size of much thickness, and thus the thickness of the first base layer 101 can be smaller than that of the second base layer 102.
Example 2
Referring to fig. 1, in some embodiments of the present invention, the first base layer 101 is partially embedded in the second base layer 102, or the second base layer 102 is partially embedded in the first base layer 101. That is, the first base layer 101 and the second integration 102 are constructed as an embedded structure.
Specifically, if the first base layer 101 is partially embedded in the second base layer 102, the width of the first base layer 101 embedded in the second base layer 102 is greater than the width of the first base layer 101 located outside the second base layer 102;
if the second base layer 102 is partially embedded in the first base layer 101, the width of the second base layer 102 embedded in the first base layer 101 is greater than the width of the second base layer 102 located outside the first base layer 101.
In some embodiments of the present invention, a mutually matching combination structure is disposed between the first base layer 101 and the second base layer 102, and includes a groove structure and a claw structure that can be clamped in the groove structure;
if the groove structure is located on the second base layer 102, the claw structure is located on the first base layer 101;
if the groove structure is located on the first base layer 101, the claw structure is located on the second base layer 102.
Hereinafter, the matching structure between the first base layer 101 and the second base layer 102 will be described by taking the example of embedding the two layers.
Processing the first base layer 101 into a structure with one wide end and one narrow end, wherein one end of the wide end is formed into a claw 1011; the groove structure 1021 is formed on the second base layer 101, and the groove structure 1021 is as critical as the shape of the first base layer 101, so that the first base layer 101 can be assembled in the groove structure 1021, and after assembly, the surface of the first base layer 101 is flush with that of the second base layer 1021. With this arrangement, the first base layer 1011 can cover only a part of the surface of the second base layer 1021.
