Abstract

The present invention provides a trabecular bone structure, which is characterized in that: it contains several cylindrical units, and the several cylindrical units form an irregular three-dimensional network structure to form a trabecular bone; wherein, the cylindrical units It includes a first end, a second end, a solid part, and a first channel, the first end and the second end are respectively located at the left and right ends of the solid part, and the first channel is opened in The solid part is disposed in the solid part and axially along the solid part, so that both ends of the first channel communicate with the first end part and the second end part respectively. Its advantages are: on the premise of ensuring the strength of trabecular bone, it also increases the intercommunication performance of trabecular bone, makes the nutrient substance transport more smoothly, increases the area of ​​metabolic site, makes the progress of bone ingrowth more rapid, and the bone grows faster. The input effect is more solid.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone trabecular structure and its application. Background technique [0002] In the case of 3D printed uniform and regular bone trabecular structure, only the pore size and porosity are guaranteed. Although it can meet the biomechanical properties and physiological microenvironment characteristics of a small part of cancellous bone, it is different from the real cancellous bone. There is still a big gap between bone structure and physiological function, because the inside of trabecular bone is closed, which has certain limitations in the transportation of nutrients such as minerals, and it is easy to cause dead space during use, which becomes a new treatment risk. Moreover, the uniform trabecular bone structure has a poor effect on bone ingrowth, and the surface roughness is low, which is not conducive to the initial stability of the prosthesis. [0003] Therefore, it ...
