Convenient Operation Cervical Interbody Fusion Device Anatomical Design

A cervical interbody fusion cage, also known as an interbody cage or cervical cage, is a medical device used in cervical spine surgery to promote fusion between adjacent vertebrae. It is primarily used to treat conditions such as degenerative disc disease, cervical herniated discs, spinal instability, and cervical spondylolisthesis.

The cervical interbody fusion cage is typically made of biocompatible materials such as titanium, polyetheretherketone (PEEK), or a combination of materials. It is designed to be inserted into the intervertebral space between two cervical vertebrae, replacing the damaged or degenerated disc.

The cage provides several functions:

1. Spinal Alignment and Height Restoration: The interbody cage helps restore the natural alignment and height of the cervical spine. It helps maintain proper disc height and spinal curvature, alleviating pressure on nerves and stabilizing the cervical segment.

2. Stabilization: The cage acts as a spacer, maintaining the separation and stability of adjacent vertebrae while promoting fusion. It prevents excessive motion between the vertebrae, facilitating the fusion process and reducing the risk of recurrent symptoms.

3. Fusion Promotion: The cage creates a favorable environment for bone growth and fusion. It allows for the ingrowth of bone and facilitates fusion between the adjacent vertebrae over time. Some cages also have porous or roughened surfaces to enhance bone integration.

Product Deisgn

• Anatomical Design

Pyramidal teeth structure prevents migration and achieve primary stability of implantation
Lordotic angle 8°
Restore cervical physiological lordosis
Superior convex design fits the lower end plate of the upper vertebral body to achieve anatomical fit

• Improve the Fusion Rate

The extra large bone grafting window increases the amount of bone graft, increases the contact surface with the upper and lower endplates, and improves the fusion rate
PEEK Material, good biocompatibility, elastic modulus close to bone, no stress shielding, improves fusion rate
15.5 mm width,enlarges the supporting surface without damaging the uncinate joint

• Convenient Operation

Decompression slots reduce pressure and make implantation more convenient
Three tantalum marker pins, convenient for fluoroscopy to observe the safe position of fusion cage
Arc surface makes the connection between inserter and cage more stable and prevent rotation. It is 2-3mm away from the anterior edge of the vertebral body, and matches the arch of the anterior edge of the vertebral body.

Product Features

• Improved Design Based on Physiological Anatomy

The functional structure of the fusion cage is designed based on anatomy, which can better restore the physiological structure of patients and achieve better treatment effect.

• The Ultimate Goal Is to Improve the Fusion Rate and Improve the Treatment Effect.

Excellent mechanical bearing structure and extra large bone graft window design significantly improve the fusion rate.
