Product Introduction
The Lumbar Fusion Cage is designed with an optimized bullet structure for easy implantation. It features a convex support surface that fits the upper and lower endplates, aligning with human anatomical structures to facilitate fusion. The cage includes a hyper bone grafting window to increase the bone graft area and improve the fusion rate. A chamfer design at the tail edge prevents postoperative stimulation of the dural sac, and a chamfer design at the tail connecting hole facilitates secondary installation during operations.

Material and Design
The cage is made from PEEK material, known for its good biocompatibility and an elastic modulus close to bone, which helps avoid stress shielding and improves the fusion rate. The beveled edge design on the teeth side prevents end plate fractures caused by stress concentration. Pyramidal teeth prevent migration and achieve primary stability of implantation. An impacting device at the end of the inserter protects against thread damage by avoiding direct strikes on the inserter shaft. Three tantalum marker pins are included for convenient observation of the cage position.

Product Specifications
The Lumbar Fusion Cage comes in various sizes with superior-inferior heights and medial-lateral widths, although specific measurements are not provided in the document. A side horizontal four-dimension comparison diagram is mentioned but not detailed.
