This specialized instrument set is designed for precise osteotomy procedures in foot and ankle surgery, providing a complete system from osteotomy planning guidance to bone surface precision grinding and compression fixation.
The set includes 17 core tools that address the challenges of osteotomy positioning and bone surface management in complex foot and ankle anatomy—including precise guidance, controlled osteotomy, efficient grinding, and stable compression—covering the closed-loop workflow from accurate guidewire implantation, grinding guidance, bone surface precision grinding to final compression fixation.
Manufactured from high-strength stainless steel and wear-resistant alloys, critical grinding components (e.g., distal/proximal grinding heads) undergo specialized surface hardening treatments to ensure bone processing efficiency and long-term operational stability.
With a core design philosophy of "Guided Positioning + Graded Grinding + Precision Compression," the system utilizes serialized threaded guidewires, matched distal/proximal grinding head sets, and specialized compression measurement tools to achieve precise preparation, angle control, and stable compression fixation of osteotomy surfaces in metatarsal, calcaneal, and other foot regions.
This effectively avoids repeat osteotomies and enhances bone healing efficiency, meeting the demands of foot and ankle corrective procedures including hallux valgus correction, metatarsal osteotomy lengthening/shortening, calcaneal osteotomy displacement, and ankle arthrodesis.
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 Guidance and Graded Osteotomy Design
The set employs "guided positioning + graded grinding" as its core technical pathway, equipped with 5 specifications of threaded guidewires (15mm-35mm) adapted to differential bone densities and anatomical approaches in foot/ankle regions (e.g., metatarsal heads, calcaneal tuberosity), achieving millimeter-level precise anchoring of osteotomy sites. Matched distal/proximal grinding head sets (Ø16mm-Ø24mm) provide five diameter gradients, completing controlled osteotomy surface grinding under rigid guidewire guidance to form highly compatible biomechanical contact surfaces, significantly reducing bone volume errors or secondary adjustment risks associated with traditional osteotomies.
Efficient Bone Processing and Surface Optimization Technology
Critical grinding components (distal/proximal grinding heads) utilize wear-resistant alloy substrates with specialized surface hardening treatments, maintaining cutting efficiency and long-term fatigue resistance in high-density calcaneal cancellous bone or metatarsal cortical bone environments. Grinding head edge designs balance bone chip evacuation fluency and thermal damage control, ensuring osteotomy surface microstructural integrity and providing an ideal biological foundation for bone healing.
Mechanical Compression and Quantified Fixation System
Through synergistic operation of compression forceps and measuring ratchet forceps, precise coaptation and dynamic compression of osteotomy ends are achieved. Ratchet forceps provide real-time pressure feedback and displacement locking functions, avoiding overload or insufficiency problems in traditional experiential compression, ensuring bone end fusion under optimal mechanical conditions.
Complete Workflow Adaptation to Complex Anatomy
The set covers the entire surgical chain from "guidewire implantation → grinding guidance → bone surface refinement → compression fixation," specifically addressing manipulation challenges in multi-curved foot/ankle bones (e.g., navicular, cuboid). Differentiated distal and proximal grinding head designs adapt to special anatomical morphologies like metatarsal bases/heads and anterior/posterior calcaneal articular surfaces, combined with guidewires' deep anchoring capability, achieving safe, controlled bone processing in confined surgical fields while reducing interference with plantar neurovascular bundles.
Millimeter-Level Osteotomy Accuracy Assurance
Through precise matching of 5-level guidewire diameter gradients (15-35mm) and 10 specifications of proximal/distal grinding heads (Ø16-24mm), the set achieves sub-millimeter control of osteotomy angles and depths. Differential guidewire thread designs ensure rigid anchoring in high-porosity calcaneal cancellous bone or high-density metatarsal cortical bone, combined with grinding heads' anatomical edge surface profiles, achieving over 95% osteotomy surface matching accuracy and completely avoiding bone loss or stepped osteotomy surfaces caused by traditional oscillating saws.
Doubled Bone Processing Efficiency
Wear-resistant alloy grinding heads with optimized chip evacuation grooves effectively enhance cutting efficiency during calcaneal grinding and extend continuous operation duration. Specialized surface hardening treatments inhibit bone adhesion, ensuring cutting stability under high loads. Separate distal/proximal grinding head structures adapt to metatarsal head curved surfaces and basal planes, completing biomechanically compatible osteotomies in single operations and effectively shortening procedure time.
Revolutionary Dynamic Quantified Compression
Combined use of measuring ratchet forceps and compression forceps creates a pressure feedback system for foot/ankle osteotomies. Ratchet scales display real-time compression values, enabling surgeons to implement stepped loading according to bone density, avoiding bone compression or internal fixation failure from overload. Compared to traditional experiential compression, this effectively improves bone end fusion rates.
Comprehensive Procedure Coverage and Economic Benefits
A single set supports mainstream procedures including hallux valgus, metatarsal deformities, calcaneal, ankle, and subtalar joint arthrodesis, replacing traditional multiple instrument combinations. Precise osteotomy reduces bone graft requirements and effectively lowers revision surgery rates.
