This instrument set is a specialized surgical kit designed for spinal deformity correction procedures using a 5.5mm spinal fixation system.
It includes 21 high-precision instruments that support the complete workflow—from pedicle screw manipulation and spondylolisthesis reduction to coronal rod contouring and final locking.
The set addresses the three-dimensional correction needs of complex deformities such as scoliosis, kyphosis, and vertebral slippage.
Constructed from premium stainless steel with excellent corrosion resistance and biocompatibility, key components (e.g., taps) are plasma nitrided for enhanced wear resistance.
Centered around the concept of "3D Precision Correction + Efficient Reduction," the system integrates powered screw insertion, coronal contouring tools, and dedicated spondylolisthesis reducers to achieve higher accuracy and surgical efficiency compared to conventional correction sets.
Material Excellence:
Main components are made from 05Cr17Ni4Cu4Nb, 465, 316L, and 304 stainless steels. Electro-polished surfaces reduce soft tissue damage and enhance fatigue strength.
Pedicle Screw Handling Tools:
● Anti-slip Pedicle Screw Gripper: Designed to securely hold 5.5mm screw heads with enhanced clamping force during reduction.
● Powered Universal and Fixed Inserters: Improve insertion efficiency over manual tools.
Dedicated Spondylolisthesis Reduction Components:
● Reduction Ball Nut & Reduction Plate: Combined with the pedicle screw gripper and plate lever mechanism, they achieve controlled vertebral lifting under C-arm guidance.
● Short & Long Connectors: Enable single-level and multi-level reduction with improved precision and force distribution compared to traditional reduction forceps.
Coronal Plane Correction Tools:
● Left & Right Coronal Rod Benders: Specifically designed for scoliosis correction with high contouring precision.
● Dual-joint Rod Rotators: Allow intraoperative rod adjustment in narrow fields, offering better grip and flexibility than single-joint models.
Support & Storage Instruments:
● Rod Pusher Sleeve: Features smooth chamfered grooves for precise rod seating without stress concentration.
● Unlocking Tool: Safely detaches the locked gripper from screws, facilitating revision procedures.
● Instrument Tray: Shock-absorbing, multi-compartment layout organized by workflow—screw handling, reduction, rod bending, and locking—for faster instrument access.
3D Deformity Correction Capability:
Coronal rod benders combined with dual-joint rod rotators offer enhanced precision in scoliosis correction.
Powered Efficiency:
Powered inserters significantly reduce screw placement time and surgeon fatigue.
Enhanced Safety:
Anti-slip screw grippers reduce the risk of screw displacement, while the spring-release unlocking tool minimizes instrument-induced damage.
Cost-effectiveness & Versatility:
One comprehensive set supports full-segment deformity correction, minimizing inventory redundancy and reducing annual maintenance costs.
