Product Introduction
The document introduces cervical and lumbar fusion cages designed for spinal surgeries. The cervical fusion cage features a superior convex design to fit the lower end plate of the upper vertebral body, ensuring an anatomical fit. It has a width that enlarges the supporting surface without damaging the uncinate joint. The arc connection surface enhances stability and prevents rotation during implantation.

Material and Design
The cages are 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 anterior-posterior conical design facilitates convenient implantation. Three tantalum marker pins are included for easy fluoroscopic observation of the cage's position.

Features
The hyper bone grafting window increases the bone graft area, enhancing the fusion rate. Decompression slots reduce pressure during implantation. The lordotic angle restores cervical physiological lordosis, while the pyramidal teeth structure prevents migration and ensures primary stability.

Product Specifications
The cervical fusion cage specifications include posterior margin heights of various measurements, a medial-lateral width of a specified dimension, and an anterior-posterior length. Notably, the anterior margin is higher than the posterior margin.
