Pediatric Spinal Surgery Instrument set (4.5 System) Introduction
This instrumentation set is specifically designed for pediatric spinal deformity correction surgeries. It combines the unique characteristics of children’s bone development with surgical precision requirements, featuring tools compatible with the 4.5mm specification system. It is suitable for complex procedures such as scoliosis correction and spondylolisthesis reduction .
Core Components and Functional Features:
- Precision Bone Handling Tools
- Includes bone drills, guide drills, and depth gauges (4.5mm) , tailored to pediatric pedicle dimensions for millimeter-level depth control, reducing intraoperative nerve injury risks.
- Osteotomy locators and angle measurement tools enable 3D spatial positioning for accurate screw trajectory planning.
- Dedicated Internal Fixation Instruments
- Self-locking retractors minimize soft-tissue trauma while optimizing surgical exposure.
- Rod rotation forceps and rod holders facilitate contouring and fixation of 4.5mm correction rods, accommodating pediatric spinal curvature reconstruction.
- Safety and Adaptability Enhancements
- Blunt-tipped bone guide needles prevent perforation of thin pediatric cortical bone.
- Quick-release handles allow rapid instrument interchange, shortening surgery duration and reducing prolonged anesthesia risks .
- Materials and Sterilization Standards
- Instruments primarily use 316L medical-grade stainless steel , ensuring strength and corrosion resistance.
- Non-sterile packaging design supports hospital-selected sterilization methods (high-temperature or low-temperature).
Typical Clinical Applications
Indicated for children aged 8–14 years with:
- Idiopathic scoliosis (Cobb angle >40° or progression >5°/year) ,
- Congenital hemivertebra resection,
- Traumatic vertebral reduction.
Compatible with pedicle screw-rod systems for 3D deformity correction .
This kit enhances surgical safety and efficiency through modular tool integration and pediatric-specific sizing , complying with national medical device standards .
Key Terminology Clarifications:
- Cobb Angle: Critical metric for scoliosis severity assessment .
- Pedicle Screw-Rod System: Primary implant for spinal stabilization .
- Non-sterile Packaging: Requires hospital sterilization before use .
