Abstract

The invention provides a bone trabecula structure. The bone trabecula structure is characterized in that the bone trabecula structure comprises a plurality of cylindrical units, and the cylindrical units form an irregular three-dimensional net structure to form a bone trabecula, wherein each cylindrical unit comprises a first end part, a second end part, a solid part and a first channel; the firstend part and the second end part are located at the left end and the right end of the solid part respectively; and the first channel is formed in the solid part and arranged in the axial direction ofthe solid part, so that two ends of the first channel communicate with the first end part and the second end part respectively. The bone trabecula structure has the advantages that on the premise that the strength of the bone trabecula is guaranteed, the intercommunication performance of the bone trabecula is improved, nutrient substances can be transported more smoothly, the metabolic site areais 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 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 ...
