Description

technical field

[0001] The invention relates to the field of medical instruments, in particular to an intervertebral fusion device (Cage), more specifically to a cervical intervertebral fusion device mainly used in surgery. Background technique

[0002] Anterior decompression and intervertebral fusion are well-established methods for treating cervical spine disorders. Trilateral cortical iliac bone graft fusion is still the gold standard, but the incidence of complications in the donor site is high, and problems such as pseudarthrosis, bone graft collapse to kyphosis, and graft bone prolapse may also occur. Therefore, more and more scholars use cervical intervertebral fusion devices to restore intervertebral height, obtain immediate stability, and finally obtain the effect of intervertebral bone fusion.

[0003] Weiner and Fraser' divided the currently used cervical intervertebral fusion cages into three main types: horizontal cylindrical fusion cages with threads (such as ...
