Designed specifically for pediatric thoracolumbar procedures, this foundational instrument set supports 4.5mm cobalt-chromium-molybdenum (CoCrMo) rod-screw systems and comprises 55 core tools.
Engineered to accommodate pediatric spinal anatomy—including smaller vertebral bodies, narrower pedicles, and higher bone flexibility—the set covers the complete workflow from bone channel preparation and precise localization to gentle reduction and accurate locking.
Ideal for congenital deformities and pediatric spinal trauma, all instruments are manufactured from premium stainless steel with excellent corrosion resistance and biocompatibility.
Critical components (e.g., fine-diameter probes, mini rod benders) undergo specialized surface finishing (Ra ≤0.1μm) to ensure safe interaction with delicate pediatric bone structures.
With a design philosophy centered on pediatric anatomical compatibility and minimally invasive precision, the set incorporates small-sized tools, controlled reduction components, and a precision locking system to facilitate safe implantation and stable fixation of 4.5mm CoCrMo implants across pediatric T1–L5 levels, significantly reducing soft tissue traction injuries compared to adult instrument systems.
Material Excellence
Instruments are constructed from medical-grade stainless steels (05Cr17Ni4Cu4Nb, 420B, 316L, 304), offering high fatigue resistance. Electropolished surfaces minimize tissue friction and intraoperative adhesion.
Multi-Size Bone Channel Preparation System
Flexible & Rigid Pedicle Probes: Both feature blunt tips to assess pedicle channel depth and wall integrity, minimizing cortical breach. The flexible probe conforms to bony channels with minimal trabecular compression, while the rigid version provides clear tactile feedback for detecting cortical boundaries.
Precision Positioning & Imaging Accessories
15mm & 20mm Ball-Tip/Column-Style Imaging Pins: Sized for smaller pediatric vertebrae, these improve radiographic clarity by 50%. Compatible pin holders feature reduced jaw profiles to avoid visual obstruction during placement, ensuring minimal positioning error.
4.5mm Rod-Specific Contouring Instruments
Rod Benders: Enable precise contouring of 4.5mm rods to match corrected spinal alignment or specific correction goals. Coronal/sagittal benders (left/right) support 3D deformity correction.
Tapping System
4.0, 4.5, 5.0mm Taps: Smaller diameters than adult systems allow safe channel preparation in narrow pediatric pedicles. Gradual sizing permits stepwise channel enlargement based on preoperative planning and intraoperative assessment, minimizing fracture risk. Each tap matches corresponding screw diameters to ensure appropriate insertion torque and reliable fixation.
Modular Tray Organization
The case is compartmentalized according to surgical sequence: positioning → bone preparation → rod-screw operation → reduction/locking. Laser-engraved identifiers reduce retrieval time and inventory errors.
Anatomically Adapted Pediatric Design
Instrument dimensions (e.g., fine imaging pins, mini benders, small bone hooks) correspond to smaller vertebral bodies, slender pedicles, and limited spinal canal space. Reduced working ends prevent over-invasion and damage to delicate structures, accommodating the flexibility of immature bone for precise operation within confined spaces.
Minimally Invasive & Gentle Handling
Miniaturized tools (e.g., short-handle inserters, small reduction forceps) reduce exposure needs and soft tissue retraction, lowering related injury risks by 40% versus adult instruments. Reduction components provide controlled, gradual force transmission to prevent bone fracture or neural injury. Ultra-smooth surfaces (Ra ≤0.1μm) minimize tissue drag and friction.
Precision Control & Mechanical Assurance
Dedicated rod benders (coronal/sagittal, left/right) support fine shaping for complex 3D correction. Rod rotators, spreaders/compressors, and derotation wrenches enable accurate mechanical adjustment. A staged locking system—including provisional and final lockers, break-off screwdrivers, and counter-torque sleeves—ensures secure fixation of 4.5mm CoCrMo rods after ideal correction, preventing loosening and avoiding over-tightening.
Comprehensive Workflow & Material Assurance
Covers the full procedure: precise awling, tapping, probe verification, screw/hook placement, trial rod measurement, rod contouring, rod placement, reduction, mechanical adjustment, and final locking. Specialized instruments (e.g., disconnectors, cross-connector wrenches) address specific scenarios. All tools are made of high-grade stainless steel for superior corrosion resistance and biocompatibility, meeting the stringent demands of pediatric spinal surgery.
