Abstract

The invention provides an interbody fusion cage which comprises: a fusion body, the fusion body comprises a first frame, a second frame and a plurality of bent plates, the bent plates are arranged between the first frame and the second frame at intervals, and a vertically-through through space is formed in the fusion body; a first plate body, the first plate body is arranged at the upper end of the fusion body, and provided with a first window communicated with the through space; and a second plate body, the second plate body is arranged at the lower end of the fusion body, and provided with asecond window communicated with the through space. According to the technical scheme, the problem that complications are caused by subsidence of the fusion cage prosthesis after operation in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an intervertebral fusion device. Background technique [0002] Intervertebral disc degenerative disease is a common orthopedic disease. Modern medicine has developed intervertebral fusion surgery to treat intervertebral disc degeneration. Common intervertebral fusion implants are usually made of titanium alloy material or PEEK material, or made of titanium alloy material by using 3D printing technology. [0003] Lumbar intervertebral fusion is one of the methods to treat spinal diseases, and more and more people receive intervertebral fusion every year. Lumbar intervertebral fusion is often due to the rigidity of the fusion device prosthesis is much greater than the rigidity of the body's own vertebral body, the fusion device prosthesis subsides after the operation, resulting in complications. Contents of the invention [0004] The main purpose of the present invention is t...
