Embodiment Construction

[0011] figure 1 Among them, the bone particle 1 includes: columnar body 2 and micropore 3; bone particle 1 is a three-dimensional structure, composed of six mutually perpendicular columnar bodies 2, and the columnar body 2 is conical, wide at the top and narrow at the bottom, and narrow at the bottom The tails are connected together to form a three-dimensional structure; the bone particle 1 contains many micropores 3; every three adjacent columns 2 can form a funnel-shaped fitting opening, which can just accommodate another columnar body 2 to embed and It is fastened; the micropores 3 can filter and deposit the calcified particles required by the bone, and provide a favorable environment for repairing the bone defect 7 .

[0012] When using, in figure 2 Among them, the hip joint disease caused a large amount of bone loss between the hip bones 4, resulting in acetabular bone defect; when the acetabular bone was grafted, a large number of bone particles 1 were placed in the bo...

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 printed microporous chimeric bone particle. Background technique [0002] There are various diseases of the hip joint, such as congenital dislocation of the hip joint, severe osteoarthritis, trauma, etc., which are often accompanied by acetabular bone defects. Bone grafting surgery is often required for treatment of acetabular bone defects, but poor shaping may occur during the operation, with less bone coverage on the outer upper edge of the acetabulum or the bottom of the acetabulum, or on the acetabular contact surface. 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 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 ...
