Abstract

The invention discloses an interbody fusion cage. The interbody fusion cage comprises a fusion cage body, a limiting part and a connecting part, wherein the fusion cage body is provided with a bone grafting cavity; the bone grafting cavity communicates with the outside in the vertical direction; the connecting part is used for fixing the limiting part in the bone grafting cavity; the limiting partis provided with a first locking plate and a second locking plate; the limiting part can deform; the first locking plate can extend upwards out of the bone grafting cavity; and the second locking plate can extend downwards out of the bone grafting cavity. According to the interbody fusion cage, the limiting part can penetrate into the upper vertebral body and the lower vertebral body only by inserting the interbody fusion cage into the interbody once, so that surgical operation steps can be reduced, and operation is easy and convenient; the problem that the interbody fusion cage is withdrawnfrom the intervertebral disc can be effectively improved through the arrangement of the limiting part; and the interbody fusion cage has the anti-retreating function, so that the surgical risk of a patient is reduced.

Description

technical field

[0001] The invention is used in the field of medical instruments, and in particular relates to an intervertebral fusion device. Background technique

[0002] Intervertebral bone graft fusion is to connect or fuse two or more adjacent vertebrae to achieve the purpose of rebuilding the stability of the spine. This fusion procedure usually involves the placement of an intervertebral cage filled with bone tissue or artificial bone within the discs of two adjacent vertebrae so that they "fused" together instead of being completely removed during surgery. / Partial resection of the nucleus pulposus and cartilage tissue in the intervertebral disc.

[0003] At present, the intervertebral fusion devices on the market are mainly divided into three types in terms of use. The first type is used in conjunction with internal fixation screws. As the operator, the doctor takes a long time to operate and has a heavy workload. The cost of surgery and consumables for both int...
