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] Embodiment 1: see figure 1 , a medical implant, which is composed of two kinds of medical implant materials. The biodegradation speed of these two medical implant materials is different. They are embedded with each other and form an interwoven composite structure to form a dense body; wherein 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 interweave and fit each other in a male-female structure to form a compact body, and the maximum space defined by the outer boundary of each medical implant material extending continuously toward its three-dimensional direction is closely related to the compact structure formed by them. The maximum space defined by the external boundaries is the same.

[0030] The two medical implant materials in this example are non-biodegradable poro...

Embodiment 2

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

[0033] The medical implant material 1 in the dense body is interwoven with the complementary structure 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 to its three-dimensional direction is equal to The largest space defined by the dense outer boundary formed by the three complementarities is the same.

[0034] Among them, medical implant material 1 is a non-biodegradable porous medical implant material, medical implant material 2 and medical implant material 3 are biodegradable medical implant materials, and the biodeg...

Abstract

The invention relates to a medical implant with a compound structure. The medical implant is formed by compounding more than two medical implanted materials and is characterized in that various medical implanted materials have different biodegradation rates; the various medical implanted materials are embedded to each other and are in an interlaced compound structure to form a dense body; the medical implanted materials still keep respective biological properties and physical and mechanical properties; and each medical implanted material is a continuous structure body. The medical implant with the structure can provide multi-layered curative spaces for reparation of an implanting position and supply longer growth time for normal structures, that is, the implanting space gradually reserved by biodegradation of the medical implanted materials is in exchange of longer growth time for the normal structures, thereby being more suitable for the natural healing process of the implanting position of an impaired host.

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 class of medical consumable materials that are planted, buried, and fixed on damaged or diseased parts of the host to support, repair, and replace their functions. They are a class of special properties and functions that are used for artificial organ reconstruction , surgical repair, physical therapy rehabilitation, disease diagnosis and treatment, materials that have no adverse effects on human tissue and blood. [0003] Medical implant materials can be classified according to the application site of the material, such as hard tissue materials such as bone, cartilage, and teeth. Among them, hard tissue materials used in orthopedics are a very important type of medical implant materials. [0004] Medical implant materials can also be classified according to the b...
