This comprehensive instrument system is designed for internal fixation of extremity fractures using locking plate technology, compatible with 4.5mm & 5.0mm diameter locking screws.
The set includes 22 core tools that address the technical challenges of open/limited open reduction and fixation—including precise reduction, anatomical adaptation, and angular stable fixation—covering the complete closed-loop workflow from fracture exposure, reduction, plate contouring, guided drilling, tapping to high-torque locking.
Manufactured from high-strength stainless steel, critical components (e.g., drill bits, taps) undergo precision grinding and reinforcement treatments to ensure efficient bone channel preparation and optimal thread quality.
With a core design philosophy of "Anatomical Reduction + Plate Adaptation + Angular Stable Locking," the system utilizes specialized reduction forceps, bidirectional plate benders, and a modular guided locking system to achieve precise fracture reduction, personalized plate contouring, and secure locking screw implantation.
This provides reliable angular stability, significantly reduces operative time and minimizes reduction loss risks, meeting the demands of open reduction internal fixation for long bone fractures (e.g., humerus, ulna/radius, femur, tibia/fibula) and nonunion revision surgeries.
Material Excellence
Instruments are constructed from premium stainless steels (05Cr17Ni4Cu4Nb, 420B, 316L, 304), offering high fatigue resistance. Electropolished surfaces minimize tissue friction and surgical trauma.
Precision Reduction and Plate Adaptation System
The set integrates pointed reduction forceps and centralized bone holding forceps to achieve anatomical alignment and stable clamping of fracture fragments. Combined with bidirectional plate benders (left/right) that support real-time intraoperative three-dimensional plate curvature adjustment, this ensures tight bone-plate contact. Large and small bone levers assist surgical field exposure, providing crucial mechanical support points for reduction procedures while significantly reducing reduction deviation risks and establishing the anatomical foundation for angular stable fixation.
Graded Bone Channel Preparation and Differentiated Formation Technology
Modular guidance systems (double-ended guides, specialized guides) enable precise screw hole positioning, while Ø3.2mm and Ø4.3mm bone drills provide graded drilling adapted to cortical/cancellous bone differential requirements. Dedicated tap sets (cortical screws, cancellous screws, locking screws) efficiently form threads according to different bone qualities and screw types. K-wires and threaded guide pins assist temporary fixation and depth guidance, with depth gauges ensuring accurate screw length matching to guarantee bone channel quality and fixation strength.
High-Torque Controlled Locking and Efficient Operational Workflow
Screw holding sleeves enable slip-free screw implantation, while T25 integrated drivers are compatible with locking screw head interfaces. Combined with quick-change handles and torque quick-change adapters, this supports rapid intraoperative instrument switching and preset torque transmission. T-handles deliver high locking force output, ensuring locking screws achieve standardized angular stable fixation. Hex drivers provide auxiliary operation, with full-process tool synergy significantly enhancing surgical efficiency.
Clinical Applicability and Core Value
Specifically designed for open reduction internal fixation of long bone fractures (humerus/ulna-radius/femur/tibia-fibula), meeting complete workflow requirements from exposure, reduction, plate contouring, drilling/tapping to final locking. The locking mechanism provides pull-out resistance and angular stability, reducing reduction loss risks. The modular instrument design simplifies operational steps and shortens procedure time, particularly suitable for complex scenarios including osteoporotic patients and nonunion revisions.
Enhanced Reduction Accuracy and Plate Adaptation Efficiency
Pointed reduction forceps and centralized bone holding forceps work synergistically to provide multidirectional mechanical control, achieving millimeter-level anatomical reduction of fracture fragments. Bidirectional plate benders support real-time intraoperative three-dimensional contouring, eliminating traditional bone-plate gaps and avoiding stress concentration and reduction loss risks from poor adaptation while reducing plate adjustment time.
Ensured Bone Channel Preparation Safety and Fixation Reliability
Graded drilling instruments (Ø3.2mm/Ø4.3mm) and guide systems minimize screw channel positioning errors while precisely avoiding neurovascular bundles. Differentiated tap sets provide customized formation solutions for high-density cortical bone regions, low-density cancellous bone areas, and locking screw holes, effectively enhancing bone-screw holding power and reducing intraoperative splitting risks.
Achieved High-Torque Controlled Locking and Operational Workflow Optimization
Torque quick-change adapters preset safety torque thresholds, combined with anti-slip groove designs in screw holding sleeves and zero-wobble transmission of T25 integrated drivers, completely preventing eccentric screw insertion. Quick-change handles enable second-level instrument switching, effectively reducing intraoperative procedural steps and significantly improving complex fracture fixation efficiency.
Expanded Complex Case Adaptability and Long-Term Stability
The locking mechanism forms a rigid frame structure providing high pull-out strength, particularly suitable for osteoporotic patients and comminuted fractures. Modular instrument design compatibility with both open and minimally invasive approaches supports secondary fixation in nonunion revision surgeries, significantly reducing postoperative reduction loss rates.
