Personalized bone-imitating trabecularism metal gasket based on 3D printing technology

Abstract

The invention discloses a personalized bone-imitating trabecularism metal gasket based on a 3D printing technology. The personalized bone-imitating trabecularism metal gasket based on the 3D printingtechnology comprises a metal bottom plate compatible with a human body, wherein an inner structural layer, a middle structural layer and an outer structural layer are sequentially arranged on the metal bottom plate through the 3D printing technology and are not limited to three antique trabecularism layers, and the porosity of the inner structural layer is smaller than that of the middle structural layer. Due to the fact that metal bottom plates with uniform specifications are manufactured in advance, fine adjustment is facilitated when the metal bottom plates need to be used; the requirementsof different patients can be met conveniently; the personalized bone-imitating trabecularism metal gasket based on the 3D printing technology can directly scan through a laser scanner to obtain fine-tuned graphs and sizes, measurement and drawing time is saved, and rapid modeling is facilitated; and models of the inner structural layer, the middle structural layer and the outer structural layer are preset in three-dimensional software, the thickness and the porosity can be adjusted, personalized construction can be quickly realized, and the requirements on operators are reduced.

Description

technical field [0001] The invention belongs to the technical field of bone-like trabecular manufacture, and in particular relates to a personalized bone-like trabecular structure metal gasket based on 3D printing technology. Background technique [0002] Trabecular bone is the extension of the cortical bone in the cancellous bone, that is, the trabecular bone is connected with the cortical bone, and forms an irregular three-dimensional network structure in the bone marrow cavity, such as loofah or spongy, which supports the hematopoietic tissue. effect. After the formation of trabecular bone until about 20 years old, the surface of trabecular bone is covered with a layer of osteoprogenitor cells or osteoblasts, because they are all on the inner surface of the bone marrow cavity, so they are commonly called endosteal cells. Osteoblasts, arranged on the surface of bone trabeculae, the cytoplasmic protrusions can connect with the cytoplasm of the surrounding osteoblasts, whic...
