Description

technical field

[0001] The invention relates to a bone-like porous biomechanical bionic design spinal fusion device, a preparation method and application thereof, and belongs to the field of biomedical materials. Background technique

[0002] Lumbar degenerative diseases such as spinal stenosis, spondylolisthesis, and intervertebral disc herniation are common spinal surgery diseases in recent years, which seriously affect the work and life of patients. Once drugs and physical non-surgical treatments fail, surgical treatment is often the only effective method . Since Bagby applied the intervertebral fusion device Cage to spinal fusion for the first time in 1988 and achieved success, various intervertebral fusion devices have come out one after another and have been widely accepted clinically. Human spinal bone tissue has complex morphology, individual size characteristics, and unique mechanical characteristics. How to accurately reconstruct and prepare a fusion cage that ma...
