Embodiment Construction

[0038] like figure 1 , figure 2 , image 3 , Figure 4 A bionic trabecular cervical fusion device is shown, the main body of the device is in the shape of a hexagonal column, the interior is a three-dimensional mesh, and square through holes 1 are opened in the middle of the upper, lower and front and rear end surfaces. A circular screw hole 2 is also provided on the right end surface of the main body of the device. Circular through holes 3 are densely arranged on the upper, lower and left and right sides of the device, and there are also prismatic tooth patterns 4 on the upper and lower sides. Fan-shaped holes 5 are densely arranged on the front and rear ends of the device. The main body material of the device can be Ti6A4V titanium alloy powder.

[0039] The preparation method comprises the following steps:

[0040] (1) Calculation of original trabecular bone parameters:

[0041] Carry out CT spiral scan of the whole vertebral body on C2 to C7 vertebral body, the con...

Abstract

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.

Description

technical field [0001] The invention relates to an instrument for human vertebral body surgery, in particular to a bionic bone trabecular cervical fusion device and a manufacturing method thereof. Background technique [0002] Traditional interbody fusion instruments are machined with polymer materials or metal materials, which can only play a role of physical support in the human body, but have technical defects that cannot induce osteogenesis and increase the rate of spinal fusion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bionic bone trabecular cervical fusion device and its manufacturing method, which overcomes the shortcomings of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the following technical solutions: [0005] A bionic bone trabecular cervical fusion device, the main body of the device is in the shape of a hexagonal column, the interi...
