The invention discloses a bionic bone trabecula cervical vertebral fusion cage. The bionic bone trabecula cervical vertebral fusion cage is characterized in that a body of the cervical vertebral fusion cage is in the shape of a hexagonal prism, the interior of the body is in the shape of a three-dimensional net, and square through holes (1) are formed in the middles of the upper end face, the lower end face, the front end face and the rear end face of the body respectively. A manufacturing method of the bionic bone trabecula cervical vertebral fusion cage comprises the following steps that 1, original parameters of the bone trabecula are calculated; 2, a target model is established; 3, specific hole unit bodies are stacked within the boundary range of the target model disorderly, the sizes of the hole unit bodies, the distance between hole units, the sizes of ribs in the hole unit bodies, the sizes of connecting ribs between the hole unit bodies and the precision and appearance precision of an integrated bone trabecula structure are set, and finally the original target model is deleted, and the bone trabecula structure obtained after filling is reserved. According to the bionic bone trabecula cervical vertebral fusion cage and the manufacturing method of the bionic bone trabecula cervical vertebral fusion cage, a cancellous bone structure of a human body is simulated in the microstructure aspect through a 3D printing product, and the technical problems that according to a traditional centrum fusion cage, only the mechanical supporting function is achieved, and a formed bone can not be induced to grow are solved.
