Problems solved by technology

[0003] Stainless steel has good toughness and good fixation effect, but its biocompatibility is poor, which can easily cause immune rejection and affect the surgical effect
Compared with stainless steel, titanium alloy has the characteristics of low quality and high strength, but its biocompatibility is still not good

Embodiment 1

[0037] In some embodiments of the present invention, the first base layer is attached 101 on the second base layer 102 . Specifically, the magnesium alloy can be made into magnesium alloy thin paper, similar to tinfoil paper, cut into 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 , the first base layer 101 can cover a part of the side end surface of the second base layer 102 as long as the contact area with the bone can be satisfied.

[0038] Only one layer of magnesium alloy structure needs to be constructed to achieve the effect of orthopedic implants promoting bone growth without designing the magnesium alloy layer to a thicker size, so the thickness of the first base layer 101 can be smaller than that of the second base layer 102 thickness.

Embodiment 2

[0040] refer to figure 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 configured as an embedded structure.

[0041] 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 outside the second base layer 102;

[0042] 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 outside the first base layer 101 .

[0043] In some embodiments of the present invention, the first base layer 101 and the second base layer 102 are provided with...

Abstract

The invention discloses an orthopaedic implant. The orthopaedic implant comprises a body, wherein the body at least comprises a first base layer and a second base layer, the first base layer is a nearbone layer in a use state relative to the second base layer, the first base layer is made of a magnesium alloy material, and the strength of the second base layer is greater than that of magnesium alloy. The magnesium alloy with higher biocompatibility is adopted and combined with other metal with higher strength to construct the orthopaedic implant, orthopaedic regeneration can be promoted, andpostoperative recovery is improved.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an orthopedic implant. Background technique [0002] In the prior art, implants for orthopedic surgery are all made of stainless steel or titanium alloy materials. [0003] Stainless steel has good toughness and good fixation effect, but has poor biocompatibility, which can easily cause immune rejection and affect the surgical effect. Compared with stainless steel, titanium alloy has the characteristics of low quality and high strength, but its biocompatibility is still not good. [0004] The characteristics of orthopedic implant products to promote bone fusion are very important. Contents of the invention [0005] The object of the present invention is to provide a class of orthopedic plants with better biocompatibility in view of the above background technical problems. [0006] In order to achieve the above purpose, in some embodiments of the present in...
