This specialized instrument set is designed for posterior pediatric thoracolumbar orthopedic procedures, compatible with 4.5mm diameter rod-screw systems.
It includes 13 core instruments that address the unique challenges of pediatric spinal surgery—minimally invasive implantation, precise reduction, and mechanical stability—covering the complete workflow from pedicle screw placement, spondylolisthesis reduction, rod insertion, to final locking.
Manufactured from medical-grade stainless steel, the instruments combine biocompatibility with high strength, while critical reduction components are precision-machined for reliable performance in confined surgical fields.
Centered on the principles of secure grasping, controlled reduction, and efficient locking, the set features a spondylolisthesis reduction plate-ball nut mechanism for controlled vertebral lifting, complemented by a modular connection system and electric screwdriving assistance.
This provides a safe, efficient, and precise integrated solution for pediatric scoliosis correction, spondylolisthesis reduction, and thoracolumbar stabilization.
Material Excellence
Instruments are manufactured from premium stainless steels (05Cr17Ni4Cu4Nb, 420B, 316L, 304), offering high fatigue resistance. Electropolished surfaces minimize tissue friction and intraoperative soft tissue damage.
Anatomically Adapted Pediatric Design
The set is specifically optimized for the delicate spinal structures and smaller bony landmarks in pediatric patients. Core tools, such as the pedicle screw holder, are designed for 4.5mm screw systems to ensure accurate placement within limited operative spaces. Thin-walled rod pushers reduce soft tissue interference, meeting the demands of minimally invasive pediatric surgery and significantly lowering intraoperative tissue injury risks.
Controlled Spondylolisthesis Reduction Mechanism
The reduction plate and ball nut work synergistically to achieve gradual, controlled vertebral lifting and restoration. The ball nut mechanism allows multi-angle force application, forming a mechanical transmission chain with connecting rods and handle rods to provide visualizable, controlled reduction force for precise correction of spondylolisthesis and spinal deformities.
Modular Connection System for Enhanced Flexibility
Comprising connection blocks, short/long connectors, and linking rods, this expandable modular system enables rapid adaptation to varying anatomical depths and reduction vectors intraoperatively. It simplifies instrument assembly, eliminates operational blind spots, and is particularly suited for complex multi-level pediatric correction procedures.
Electric-Assisted Locking for Efficiency and Precision
The electric universal screwdriver enables multi-angle pre-tightening of screw heads, facilitating initial fixation after rod placement. The electric fixed screwdriver delivers high torque output for reliable final locking. Electric tools significantly reduce surgeon fatigue, shorten locking time, and prevent torque inconsistency associated with manual operation.
Integrated Reduction and Rod Seating Workflow
The rod pusher and sleeve wrench form a closed-loop process for rod placement, seating, and locking: the pusher accurately guides the rod into the screw tulip and applies vertical pressure, while the wrench completes high-torque final locking. Combined with the disconnector's emergency release function, this ensures a safe and controllable surgical process.
Significantly Reduced Pediatric Surgical Risks
Anatomically adapted designs (e.g., 4.5mm screw holders, thin-walled rod pushers) and high-strength materials mitigate risks to delicate pediatric spinal structures. The reduction plate-ball nut mechanism provides visualizable, gradual reduction force, avoiding violent maneuvers that could cause vertebral fracture or neural traction injuries—especially critical in patients with incomplete bone development.
Improved Success Rates in Complex Deformity Correction
The modular connection system (connection blocks + short/long connectors + linking rods) supports multi-dimensional force transmission, flexibly adapting to varying spinal curvatures and depths in the thoracolumbar region. Combined with the electric universal screwdriver's precise angular adjustment capability, it enables synchronous three-dimensional correction in scoliosis surgery, reducing postoperative residual deformity rates.
Reduced Operative Time and Streamlined Workflow
Electric-assisted tools (electric screwdrivers) enable rapid, high-torque locking of individual screws, significantly improving efficiency. Modular components allow quick intraoperative assembly and conversion, while standardized case organization minimizes non-operative time—particularly beneficial for risk management during lengthy pediatric surgeries.
Comprehensive Coverage of Key Surgical Needs
From pedicle screw insertion (screw holder), vertebral lifting (reduction plate-ball nut), and rod placement (rod pusher) to final locking (electric screwdrivers + sleeve wrench), the set provides a complete solution for pediatric spinal procedures. It covers three core indications—spinal fractures, scoliosis correction, and lumbar spondylolisthesis—eliminating workflow interruptions caused by intraoperative instrument changes.
