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 0.1 mm.

[0032] In this embodiment, the interlaced trabeculae 4 form the trabecular bone structural hole 5, the porosity of the trabecular bone structural hole 5 on the trabecular bone structure body is 30%, and the aperture range of the trabecular bone structural hole 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 th...

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 bone structure hole 5, the porosity of the trabecular bone structure hole 5 on the trabecular bone structure body is 50%, and the aperture range of the trabecular bone structure hole 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 th...

Abstract

The invention relates to the technical field of medical prostheses, and provides a bone trabecula structure. The bone trabecula structure comprises a bone trabecula structure body, the bone trabeculastructure body is composed of a plurality of mutually-staggered trabeculae, and the mutually-staggered trabeculae form bone trabecula structure holes; a hole structure is arranged in each bone trabecula structure body, each hole structure comprises a plurality of side face holes and a plurality of transverse holes, and the multiple side face holes and the multiple transverse holes are mutually crossed; and part of the multiple side face holes are perpendicular to the axis of each bone trabecula structure body, and part of the multiple side face holes are obliquely arranged. The bone trabeculastructure has the beneficial effects that pores are designed in the transverse directions and the longitudinal directions of the trabeculae of the bone trabecula structure body, so that the strength of the bone trabecula structure is guaranteed, the intercommunity is improved, nutrients and other substances can be transported more smoothly, the metabolic site area is increased, the bone ingrowth progress is quicker, and the bone ingrowth effect is firmer.

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 ...
