Problems solved by technology

[0003] In order to overcome the problems of insufficient stability in shaping and low bone repair rate in the current bone grafting process, the present invention provides a 3D printed microporous chimeric bone particle, which can be generated by 3D printing, It can provide a favorable environment for bone repair when used in bone grafting surgery. It can not only stably and effectively shape the bone during the bone grafting process, but also improve the rate of bone repair

Embodiment Construction

[0011] figure 1 Among them, the bone particle 1 includes: a columnar body 2 and a micropore 3; the bone particle 1 is a three-dimensional structure, consisting of six mutually perpendicular columnar bodies 2, and the columnar bodies 2 are all truncated, with a wide upper part and a narrow lower part, and the lower part is narrower. The tails are connected together to form a three-dimensional structure; the bone particles 1 contain many micropores 3; every three adjacent columnar bodies 2 can form a funnel-shaped fitting opening, which is just able to accommodate another columnar body 2 to embed and insert. It is clamped tightly; the micropores 3 can filter and deposit the calcified particles required for bone formation, providing a favorable environment for repairing the bone defect site 7 .

[0012] When in use, in figure 2 , due to hip joint disease caused a large amount of bone loss between the hip bones 4, resulting in acetabular bone defect; when bone grafting was perfo...

Abstract

A 3D (three-dimensional) printing micropore inlaying type bone grain comprises columnar bodies and micropores; the bone grain has a three-dimensional structure and consists of the six columnar bodies which are perpendicular to one another; the columnar bodies are in the shape of a circular truncated cone and have wide tops and narrow bottoms; narrow tails of the lower portions of the columnar bodies are connected together to form a three-dimensional structure; the bone grain comprises a plurality of micropores; and each three adjacent columnar bodies can form a funnel-shaped inlaying opening. The 3D printing micropore inlaying bone grain can provide an enabling environment for bone repair; shaping can be carried out stably and effectively in a bone grafting process; and bone repair rate can be improved.

Description

technical field [0001] The invention relates to a bone particle, in particular to a 3D printing microporous embedded bone particle. Background technique [0002] Hip joint diseases are diverse, such as congenital hip dislocation, severe osteoarthritis, trauma, etc., which are often accompanied by acetabular bone defects. Bone graft surgery is often required for acetabular bone defects, but poor shaping may occur during the operation, with less bone coverage on the outer upper edge of the acetabulum or acetabular floor, or on the contact surface of the acetabulum. In the case of insufficient bone mass, the bone graft site is prone to loosening after surgery, resulting in a low rate of bone repair. Contents of the invention [0003] In order to overcome the problems that the shape is not stable enough and the bone repair rate is not high in the current bone grafting process, the present invention provides a 3D printed microporous embedded bone particle, the 3D printed micro...
