Problems solved by technology

[0007] (3) Although the trabecular structure is interconnected in a non-uniform state, the interior of the trabeculae is closed, and there are certain limitations in the transportation of nutrients such as minerals and the strength of bone bonding.

Embodiment 1

[0031] Please refer to the attached Figure 1-3 The purpose of this embodiment is to provide a trabecular bone structure, including: a trabecular bone structure body, the trabecular bone structure body is composed of several interlaced trabeculae 4, and the diameter of the trabecular 4 is 0.1mm.

[0032] In this embodiment, the interlaced trabeculae 4 form the trabecular structural holes 5, the porosity of the trabecular structural holes 5 on the trabecular bone structure body is 30%, and the aperture range of the trabecular structural holes 5 is 0.1 mm. It is worth mentioning that the structure of the trabecular bone is non-uniform and irregular, which not only ensures the pore size and porosity, but also can be designed according to the real situation of the cancellous bone trabecular bone in different parts of the human body. First, the wire diameter and porosity of trabecular 4 are infinitely close to the real state of human cancellous bone, which improves the adhesion, p...

Embodiment 2

[0038] Please refer to the attached Figure 1-3 , The purpose of this embodiment is to provide a trabecular bone structure, including: a trabecular bone structure body, the trabecular bone structure body is composed of a number of interlaced trabeculae 4, and the diameter of the trabecular 4 is 1mm.

[0039] In this embodiment, the interlaced trabeculae 4 form the trabecular structural holes 5, the porosity of the trabecular structural holes 5 on the trabecular bone structure body is 50%, and the aperture range of the trabecular structural holes 5 is 1.2 mm. It is worth mentioning that the structure of the trabecular bone is non-uniform and irregular, which not only ensures the pore size and porosity, but also can be designed according to the real situation of the cancellous bone trabecular bone in different parts of the human body. First, the wire diameter and porosity of trabecular 4 are infinitely close to the real state of human cancellous bone, which improves the adhesio...

Abstract

The invention relates to the technical field of medical prosthesis and provides a bone trabecular structure. It includes: a trabecular bone structure body, the trabecular bone structure body is composed of a number of interlaced trabeculae, and the interlaced trabeculae form a trabecular bone structure hole; a hole structure is arranged inside the trabecular bone structure body , the hole structure includes a number of side holes and a number of transverse holes, and a number of side holes intersect with a number of the transverse holes; wherein, some of the side holes are arranged perpendicular to the axis of the trabecular structure body, and some Several side holes are arranged obliquely. The beneficial effect of the present invention is that: the body of the trabecular bone structure is designed with holes in the transverse and longitudinal directions of the trabecular bone, which not only ensures the strength of the trabecular bone structure, but also increases the intercommunication, so that nutrients and other substances can be transported more smoothly, increasing the The site area for metabolism is reduced, the progress of bone ingrowth is accelerated, and the effect of bone ingrowth is more reliable.

Description

technical field [0001] The invention relates to the technical field of medical prosthesis, in particular to a bone trabecular structure. Background technique [0002] Cancellous bone is composed of a large number of interwoven bone trabeculae, which are spongy and arranged in the same direction as the pressure and tension on the bone. It follows the principle of using the minimum bone mass to achieve the maximum bone strength to support and relieve Functions such as weight, cushioning, accommodating bone marrow, coping with strain, and adapting to deformation. Trabecular bone is widely distributed in the human body. Although cancellous bone only accounts for 20% of the human bone mass, it constitutes 80% of the bone surface and contains various structures such as collagen, minerals, and bone tissue cells. The place where this metabolism takes place is also an important birthplace of the blood system. [0003] Bone defect is a common clinical disease, and it is also one of ...
