Problems solved by technology

[0004] In view of the above problems, the present invention provides an artificial bone structure, which can solve the problem that body fluid or bone marrow cannot penetrate and flow after the artificial bone is implanted in the body due to the inability of the pores in the artificial bone made of the existing foam metal material to penetrate. It is closer to natural bones, which is conducive to the growth and combination of artificial bones and natural bones

Embodiment Construction

[0029] The artificial bone structure of the present invention includes an artificial bone body 1, and a plurality of cavities penetrating through the artificial bone along the length direction are opened inside the artificial bone body 1, thereby forming a hollow structure in the artificial bone body.

[0030] See figure 1 , several cavities are formed by several bone pores 2, and several bone pores all penetrate the artificial bone body along the bone length direction to form a hollow structure; several bone pores 2 are evenly distributed on the radial surface of the artificial bone body, and the bone pores 2 The density is 10% to 90%; a number of bone pores 2 can also be gradually distributed from the inside to the outside according to the gradual transition from sparse to dense on the radial surface of the artificial bone body, see Figure 11 ; There are therapeutic drugs built into the bone pores 2; several bone pores are distributed in layers along the length direction of...

Abstract

The invention provides an artificial skeletal structure which can lower elasticity modulus of an artificial skeleton made of biological titanium alloy to enable the artificial skeleton to be more similar to a natural skeleton. The artificial skeletal structure comprises an artificial skeleton body and is characterized in that the artificial skeleton body is internally provided with a plurality of cavities which penetrate through the artificial skeleton in the length direction, and accordingly a hollow structure in the artificial skeleton body is formed.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to an artificial bone structure. Background technique [0002] Among metal biomaterials, the first-generation stainless steel and the second-generation cobalt-chromium or cobalt-chromium-molybdenum alloys are not conducive to the reconstruction and healing of natural bone tissue after implantation because their elastic modulus is much higher than that of natural bone. Gradually reduce. Compared with the first and second generation metal biomaterials, biological titanium alloys have obvious advantages, for example, very ideal biocompatibility, excellent corrosion resistance, high fatigue strength, low elastic modulus, so titanium alloys are Metallic biomaterials are ideal for long-lasting or permanent human implants. [0003] Although the elastic modulus of bio-titanium alloys is much lower than that of the first and second-generation metal biomaterials, it is still higher t...
