The screw adopts a gradual inner diameter design, reducing the risk of stress concentration and significantly reducing the probability of intraoperative/postoperative nail breakage; Wet sandblasting surface treatment technology improves fatigue strength by about20-30%, extending the service life of the implant.

Anterior tapered thread with self-tapping edge simplifies implantation and prevents damage to the bone structure; The posterior cortical bone thread design enhances the holding power of the bone-screw interface and reduces the risk of loosening.

The screw-rod connection adopts an offset trapezoidal thread locking structure, which concentrates the vertical pressure and improves the torsion resistance; Bilateral screw axes intersect at nearly right angles, achieving three-dimensional fixation of the spine,which is better than traditional single-plane fixation. II.Minimally invasive and precise implantation technology

Supports percutaneous insertion (four 1cm incisions), avoiding stripping of paraspinal muscles and ligaments and reducing intraoperative bleeding by more than 50%;

Combined with C-arm or ARnavigation, the accuracy of nail placement is increased to 95%+, reducing the risk of neurovascular mishap;
