Acts as the core locking component of the pedicle screw‑rod system, securely locking the longitudinal rod inside the pedicle screw head to maintain the overall stability of the fixation construct.
Available in three configurations with a unified diameter of Φ10 mm, fully compatible with corresponding pedicle screw systems to meet varied clinical requirements.
Standard Type I / II: Delivers stable and reliable threaded locking force to firmly secure the connecting rod and maintain surgical correction alignment, indicated for routine spinal fixation and fusion procedures.
Auto‑break off Type I / II: Features a predetermined torque‑breakpoint design; the tail section fractures automatically when the optimal tightening torque is reached, avoiding thread damage and stress concentration caused by over‑tightening, eliminating the need for intraoperative cutting and streamlining the surgical procedure.
Auto‑break off, Reduction Type I / II: Combines self‑breaking locking function with reduction‑adapted design, enables reliable locking after vertebral body reduction performed with reduction screws, suitable for spinal deformity correction procedures requiring vertebral reduction.
Manufactured from biocompatible titanium alloy with excellent mechanical strength and tissue compatibility, suitable for long‑term in‑vivo implantation.
Internal drive profile matches standard surgical instruments, ensuring precise engagement and convenient intraoperative handling to improve implantation efficiency.
