Convenient Expandable Lumbar Interbody Cage Post Implantation Stabilization

After the lumbar intervertebral disc is removed, it is implanted into the intervertebral space for fusion and fixation, which can be used for PLIF, TLIF, MIS-TLIF and other operations.

Product Design

• Anatomical Design

Convex support surface fits the upper and lower endplates, more in line with the human anatomical structure and facilitate fusion

• Post-implantation Stabilization

Pyramidal teeth prevent migration and achieve primary stability of implantation.
The design of beveled edge on the teeth side prevents the stress concentration during the contact between the cage and the end plate, and prevents the end plate fracture after operation.

• Improve the Fusion Rate

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.

• Convenient Operation

Optimized bullet structure for easy implantation
Chamfer design of tail edge prevents postoperative stimulation of dural sac.
Add an impacting device at the end of the inserter to avoid exerting force on the thread at the connection part, causing the connection to loosen or even damage the thread.
Chamfer design of tail connecting hole facilitates the secondary installing of inserter when adjusting during operation
Three tantalum marker pins are convenient to observe the cage position.

Product Features

• Comprehensive Consideration of Immediate Fixation and Long-term Stability

Pyramidal teeth, preventing migritation, excellent primary stability
Extra large bone graft window, improving fusion rate and good long-term stability

• Convenient Intraoperative Operation

The improved bullet-tip design matching the inserting instrument that can be quickly assembled make the operation process convenient and fast.
The tail connection is specially designed to facilitate placement and adjustment during operation.

• Robot Empowerment

Cooperate with the "intelligent woodpecker" robot to plan the specification and implantation path of the cage, and calibrate the implantation position in real time during the operation.
