Problems solved by technology

[0008] In the prior art, a biomedical implant material is also used as the base layer to solve the support strength, and then another biomedical implant material is coated on it to impart certain biocompatibility and bioactivity. It is only a surface combination, and the medical implant of this composite structure still cannot well match the natural healing process of the damaged host, which is not conducive to the repair of the damaged or lesioned part of the host

Embodiment 1

[0028] Example 1: see figure 1 , a medical implant, which is composed of two medical implant materials. The biodegradation rates of the two medical implant materials are different. Any medical implant material still maintains its own biological properties and physical and mechanical properties, and each is a continuous structure.

[0029] see further figure 1 , the medical implant material 1 and the medical implant material 2 are intertwined and fitted with each other in a male-female mold structure to form a dense body, and the maximum space defined by the outer boundary of each medical implant material extending continuously in its three-dimensional direction is the same as the dense body formed by them. The maximum space bounded by the outer boundary is the same.

[0030] The two medical implant materials in this example are non-biodegradable porous medical implant materials (such as porous medical metal implant materials, porous medical ceramic implant materials) and bio...

Embodiment 2

[0032] Example 2: see figure 2 , a medical implant, which is an interwoven dense body composed of three kinds of medical implant materials with different biodegradation rates completely interlocked; any medical implant material still maintains its own biological properties and physical properties. Mechanical properties, and self-contained as a continuous structure.

[0033] The medical implant material 1 in the compact body is interwoven and fitted with the complementary structures of the medical implant material 2 and the medical implant material 3, and the maximum space defined by the outer boundary of each medical implant material extending continuously in the three-dimensional direction is the same as that of the medical implant material. The maximum space defined by the dense outer boundary formed by the three complementarities is the same.

[0034] The medical implant material 1 is a non-biodegradable porous medical implant material, and the medical implant material 2 ...

Abstract

A medical implant having a composite structure is formed by combining more than two medical implant materials. The biodegradation rates of the medical implant materials are different. The medical implant materials are fitted to each other and present an intertwined composite structure to form a dense body. Each of the medical implant materials still maintains the respective biological properties and physical and mechanical properties, and is of a continuous structure. Such a structure can provide a multi-layer healing space for repair of an implanted part and win longer growth time for the normal tissue.

Description

technical field [0001] The invention relates to a medical implant material, in particular to a medical implant with a composite structure. Background technique [0002] Medical implant materials refer to a special type of medical consumable materials that are planted, buried, and fixed in the damaged or diseased part of the host to support, repair, and replace their functions. , Surgical repair, physiotherapy rehabilitation, disease diagnosis and treatment, materials that have no adverse effect on human tissue and blood. [0003] Medical implant materials can be classified according to the material application site, such as bone, cartilage, teeth and other hard tissue materials. Among them, hard tissue materials used in orthopaedics are a very important type of medical implant materials. [0004] Medical implant materials can also be classified according to the biodegradation properties of the materials, such as biodegradable medical implant materials and non-biodegradable ...
