Artificial skeleton particles with stable effective shaping function and bone repair rate increasing function

Abstract

The invention discloses an artificial bone particle with stable and effective shaping to improve bone repair rate. The main body includes a plurality of extension bases, one end of the plurality of extension bases is connected to the central body, and the other ends of the plurality of extension bases respectively go in different directions. Extended, a plurality of through holes are distributed on the extended base body, the extended base body includes a first base column and a second base column, the first base column and the second base column are arranged symmetrically, and the diameter of the first base column gradually becomes larger from the inside to the outside , the diameter of the second base column gradually decreases from the inside to the outside. The invention provides artificial bone particles with stable and effective shaping and improved bone repair rate, which are firmly connected and can provide a favorable environment for bone repair when used in bone grafting operations. In the process of bone grafting, they can not only shape stably and effectively, but also It can improve the bone repair rate, is convenient to use, easy to operate, meets the needs of use, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of bone repair, in particular to artificial bone particles with stable and effective shaping to improve bone repair rate. 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. The existing bone particles have defects such as the internal environment is not conducive to the growth of osteoblasts, and the connection between bone particles is not relia...
