Abstract

The invention relates to the technical field of medical implant materials, and discloses a composite unit for bone implants, which includes several structural units. One end of the connecting rod is respectively connected with the first bearing surface, and the other ends of the multiple connecting rods are respectively connected with the second bearing surface. The first bearing surfaces of the structural units are merged in sequence to form a porous structure, the radii of the two end surfaces of the connecting rod increase one by one from the head end to the tail end of the porous structure, and the second bearing surfaces of the tail ends of the two porous structures are merged to form a composite unit. The invention also discloses a porous support for bone implants and a preparation method of the porous support for bone implants. The beneficial effect is that the elastic modulus is low, and it is suitable for bearing bending load.

Description

technical field [0001] The invention relates to the technical field of medical implant materials, in particular to a composite unit for bone implants, a porous support and a preparation method. Background technique [0002] In the field of bone tissue engineering, metal porous implants are the focus of research. By designing the pore structure, the metal material can be matched with the natural bone tissue of the human body in terms of mechanical properties and biological properties. Although the research in this direction has been carried out for many years, the practical application of bone tissue engineering is still subject to multiple limitations. Among them, the individual differences in the service environment of implants lead to the difficulty of standardization, which is an important restrictive factor. Most of the existing research simplifies the practical application and uses more intuitive standards for evaluation. From the perspective of mechanical compatibil...
