This foundational instrument set is designed for posterior thoracolumbar fixation using 5.5mm/6.0mm cobalt-chromium-molybdenum (CoCrMo) rod-screw systems.
The 44 precision instruments cover the full surgical workflow—from anatomical localization and bone channel preparation (awling, drilling, tapping) to rod insertion, contouring, reduction, and final locking.
Made of high-grade stainless steel with excellent corrosion resistance and biocompatibility, key components such as taps feature ion-nitrided surfaces for increased hardness and wear resistance.
Designed for comprehensive functionality and optimized CoCrMo system compatibility, the set supports mild to moderate instability corrections (e.g., fractures, spondylolisthesis) with multi-size bone preparation tools, universal reduction components, and a precision locking system.
Superior Materials:
Instruments are manufactured from premium stainless steels (05Cr17Ni4Cu4Nb, 420B, 316L, 304), offering high fatigue strength. Electropolished surfaces reduce tissue friction and adhesion.
Multi-Size Bone Channel Preparation System:
Includes tapered awls, 2.5mm straight/curved awls, and 3.2mm straight awls. Dual diameters and straight/curved designs accommodate varying pedicle screw dimensions; curved awls improve trajectory accuracy by avoiding transverse process interference.
Flexible (soft) and rigid pedicle probes feature blunt tips to assess channel depth and wall integrity, minimizing cortical breach. The soft probe flexes along bony channels with minimal trabecular compression, while the rigid probe provides clear tactile feedback for detecting cortical boundaries.
Precision Positioning & Imaging Accessories:
Ball-tip and column-style imaging pins enhance radiographic clarity. Locking pin holders ensure secure placement and reduce positioning error under C-arm guidance.
Dedicated Rod Contouring Instruments:
Rod benders and in-situ benders (left/right) enable precise shaping of 5.5mm/6.0mm rods to match thoracolspinal curvature, reducing stress concentration and fracture risk.
Optimized Tapping Performance:
Four tap sizes (5.0, 5.5, 6.0, 6.5mm) feature deepened flutes for efficient chip evacuation and reduced clogging in mixed corticocancellous bone.
Modular Tray Organization:
The case is compartmentalized according to surgical sequence (positioning → bone preparation → rod-screw operation → reduction/locking). Laser-engraved identifiers minimize retrieval time and counting errors.
Enhanced Pedicle Probing Accuracy:
The dual soft/rigid probe system accommodates varying bone densities—cortical-dominant thoracic and cancellous-dominant lumbar regions—reducing pedicle breach rates and nerve injury risk.
Streamlined Operative Efficiency:
A T-handle with quick-change coupling and dual-ended set screw drivers shorten locking time. Pre-contoured trial rods (200mm/500mm) reduce intraoperative trimming and repeated bending.
Improved Reduction & Correction Outcomes:
Hinged spreaders (L/R), compressors, frog clamps, and double-joint rod rotators enable 3D vertebral manipulation, improving correction in scoliosis and spondylolisthesis cases.
Cost Efficiency & Reusability:
One set accommodates all spinal levels, reducing segment-specific instrument needs. Compatibility with mainstream 5.5mm/6.0mm CoCrMo systems helps minimize hospital inventory costs.
