The invention provides an interbody fusion cage, which is applied to the field of medical instruments, and the interbody fusion cage comprises a first workpiece, the first workpiece is provided with afirst contact surface and a first combination surface which are opposite to each other, wherein the first contact surface is used for being in contact with a vertebral surface, the first combinationsurface is provided with an extension arm, and the tail end of the extension arm is provided with a first limiting piece;a second workpiece is provided with a second contact face and a second combination face which are opposite, wherein the second contact face is used for making contact with the vertebra face, and the second combination face is opposite to the first combination face; an accommodating groove, wherein the second combination surface is provided with theaccommodating groove for accommodating the extension arm and the first limiting piece, and the accommodating groove is provided with a second limiting piece matched with the first limiting piece; and strutting piece is used for being propped between the first combined surface and the second combined surface; when the extensionarm is contained in the accommodating groove, the first workpiece and the second workpiece can be relatively away from or close to each other, and the first limiting piece and the second limiting piece are matched to limit the first workpiece and the second workpiece which are relatively away from each other.
Description
technical field [0001] The present application relates to the field of medical devices, in particular to an intervertebral fusion device. Background technique [0002] It has been more than 100 years since the first report of spinal fusion surgery in 1911. Spinal fusion surgery has become a classic surgical procedure recognized by the spinal surgery community for the treatment of spinal surgery-related diseases. The key step in spinal fusion surgery is to restore spinal stability through bone graft fusion after releasing nerve compression. According to the different parts of bone graft fusion, it can be divided into two main methods: intervertebral bone graft fusion and posterolateral bone graft fusion. Among them, intervertebral bone graft fusion is currently the most important method for the clinical treatment of spinal related diseases (such as cervical spondylosis, lumbar degenerative diseases, etc.). ) mainstream fusion method. Intervertebral bone graft fusion is to c...
