This specialized instrument set is designed for complex fracture treatment and corrective osteotomies in wrist and ankle surgery, compatible with 2.4mm and 2.7mm locking screw systems to provide minimally invasive, precise, and rigid fixation solutions with anatomical plates.
The set includes 24 core tools that address the technical challenges of complex wrist/ankle anatomy, confined operating spaces, and multi-planar fixation requirements—including precise positioning, variable-angle screw placement, and low-trauma manipulation.
It covers the complete closed-loop workflow from accurate guidewire positioning, efficient bone channel preparation, screw angle selection, plate contouring to final high-precision locking. Manufactured from high-strength stainless steel, critical cutting components (e.g., taps, drill bits) undergo specialized surface hardening treatments to ensure cutting efficiency and durability in dense bone.
With a core design philosophy of "Anatomical Adaptation + Angular Variability + Rigid Fixation," the system utilizes precision guidance systems, universal drilling components, controlled torque handles, and specialized contouring tools to achieve low-trauma implantation and stable fixation of wrist/ankle plates, significantly reducing soft tissue and periosteal dissection.
It meets the core demands for minimally invasive techniques, anatomical reduction, and rigid fixation in procedures including distal radius fractures, metacarpal/phalangeal fractures, foot/ankle fractures, ankle arthrodesis, and corrective osteotomies.
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 Minimally Invasive Positioning and Bone Channel Preparation
The set's core capability lies in achieving precise minimally invasive manipulation in complex wrist and ankle anatomical regions. Two specifications of triangular guidewires provide initial accurate positioning, establishing the foundation for subsequent steps. Matching Ø2.4/Ø1.8 and Ø2.7/Ø2.0 double-ended drill guides, combined with specialized drill bits and sleeves, ensure rapid, stable, and coaxial drilling across different screw hole specifications, efficiently completing bone channel preparation while minimizing tissue damage.
Universal Angle Locking and Flexible Adaptation
Addressing the complex bone morphology and variable fixation angle requirements in wrist/ankle regions, the set specifically includes 1.8mm and 2.0mm universal double-ended drill guides. These guides allow surgeons to flexibly adjust locking screw insertion angles within a limited range, breaking through traditional fixed-angle limitations and significantly enhancing anatomical plate adaptation and fixation adaptability on complex bone surfaces (e.g., distal radius articular surface, peri-ankle regions), meeting personalized surgical needs.
Specialized Bone Channel Formation and Reliable Thread Matching
To ensure optimal holding power and stability for different screw types (compression screws, standard locking screws, universal locking screws) in bone, the set provides a highly specialized tap series. Each tap is optimized for specific screw thread designs, ensuring precise matching between tapped bone channels and screws, providing reliable assurance for final rigid fixation.
Controlled Torque Locking and Secure Fixation
The set emphasizes controllability during screw implantation and safety in final fixation. Through T8 star drivers, tapered drivers, precision torque handles, and quick-connect systems, surgeons can accurately apply preset torque for screw locking. This controlled torque transmission mechanism effectively prevents bone cutting or thread failure from over-tightening and fixation loosening from under-tightening, ensuring reliable locking mechanism activation and achieving rigid, stable internal fixation.
Significantly Enhanced Fixation Adaptability in Complex Anatomical Regions
The set's universal drill guides provide limited adjustable screw insertion angles, combined with specialized plate bending forceps' intraoperative three-dimensional contouring capability, enabling plates to perfectly adapt to irregular bone contours like distal radius and ankle joints. This high anatomical adaptability solves the core challenges of variable wrist/ankle bone morphology and confined fixation space, providing a reliable rigid fixation foundation for complex fractures (e.g., comminuted distal radius fractures) and corrective surgeries (e.g., osteotomies), significantly reducing reduction loss risks.
Achievement of Precise, Safe Rigid Fixation
Specialized taps optimized for different thread characteristics of compression, locking, and universal locking screws ensure precise screw-to-bone channel matching. Combined with controlled torque handle systems and precision drivers, surgeons can strictly complete locking according to preset torque. This mechanism effectively eliminates bone cutting or screw fracture from over-tightening and fixation loosening from under-tightening, achieving mechanically reliable stable fixation on small bones and creating conditions for early functional exercise.
Optimized Surgical Efficiency and Operational Fluidity
Modular guidance systems and double-ended design tools significantly reduce intraoperative instrument change frequency. Efficient triangular guidewires and depth gauges ensure accurate positioning and rapid screw length matching. Screw holding sleeves and screw holding forceps address manipulation challenges of small screws in confined spaces. Full-process tool synergy greatly shortens procedure time and reduces surgeon operational fatigue, particularly beneficial for complex surgeries requiring multi-planar fixation.
Reduced Surgical Trauma and Complication Risks
Instrument miniaturization (e.g., 1.2mm guidewires, small screw holding sleeves) and precision guidance technology minimize soft tissue and periosteal dissection. Controlled torque locking prevents mechanical complications at the source. Anatomically matched fixation reduces tendon and nerve irritation. Compared to traditional methods, the overall solution significantly alleviates postoperative pain and swelling, reduces infection, internal fixation failure, and revision surgery risks, and accelerates patient recovery—particularly beneficial for foot/ankle surgery in high-risk populations like diabetic or osteoporotic patients.
