This specialized instrument set is designed for traumatic fixation in hand, foot, extremity, and pelvic procedures, compatible with 2.5mm and 3.0mm diameter ball-tip/double-end cannulated screws.
The system includes 17 core tools that address the technical essentials of small-incision or percutaneous screw placement—precise guidance, minimally invasive access, depth control, efficient tapping, and reliable locking.
It covers the complete workflow from guidewire positioning, minimally invasive drilling, depth measurement, and tapping to secure screw implantation and final tightening.
Manufactured from high-strength stainless steel, critical components (e.g., cannulated drills, taps) undergo precision machining and specialized treatment to ensure rigidity, sharpness, and radiographic visibility in confined operating spaces.
With a design philosophy centered on "Minimally Invasive Access + Precision Guidance + Reliable Fixation," the system utilizes dual-hole drill sleeves for stable guidance, drill stoppers for precise depth control, pressure sleeves for assisted compression, and dedicated driver systems to achieve stable screw implantation in cancellous bone regions.
This significantly reduces soft tissue damage and meets the demands of minimally invasive internal fixation for hand/foot fractures (e.g., scaphoid, talus), wrist/elbow/ankle arthrodesis, pelvic fixation, pediatric fractures, and metaphyseal fractures of extremities.
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.
Comprehensive Minimally Invasive Workflow
The set provides a complete operational chain from guidewire positioning to final screw locking. The φ1.1mm ball-tip guidewire enables initial positioning and temporary fixation, while the φ2.0mm cannulated drill establishes the minimally invasive bone channel. The φ4mm cannulated countersink optimizes screw head seating; the depth gauge provides real-time depth measurement; cannulated taps efficiently prepare threads under guidewire guidance. Screw holding sleeves and forceps ensure accurate screw delivery, while the pressure sleeve system assists fragment compression. Final high-torque locking is achieved with T8 cannulated/standard hex drivers and quick-connect handles, meeting the complete workflow requirements for minimally invasive fixation in hand, foot, and pelvic regions.
Dual Assurance of Precision and Safety
Multi-level guidance and depth control designs significantly enhance operational accuracy: dual-hole drill sleeves provide stable drilling guidance to prevent intraoperative deviation; drill stoppers and stopper wrenches precisely control drilling depth to avoid penetration risks; depth gauges verify bone channel depth in real-time to ensure proper screw length selection; φ1.0mm guidewire cleaners maintain channel patency or confirm pathway integrity. All instruments feature high-strength stainless steel construction with precision-machined critical components to ensure rigidity and radiographic visibility.
Efficient Minimally Invasive Operation and Damage Control
Reliable fixation through sub-centimeter incisions: the φ2.0mm micro cannulated drill creates minimal bone window access, significantly reducing soft tissue damage; ball-tip guidewires combine precise penetration with temporary fixation, eliminating repeated positioning; cannulated taps and drills maintain guidewire continuity throughout operation, reducing instrument changes; periosteal elevators assist limited exposure while protecting neurovascular structures. The entire workflow minimizes surgical trauma, particularly suitable for areas with thin soft tissue coverage like wrist, ankle, and foot regions.
Modular Instruments Enhance Operational Convenience
The T8 dual-driver system allows screw locking with guidewire in place (cannulated hex) and final reinforcement (standard hex), adapting to varying intraoperative needs; quick-connect handles enable single-click driver changes, improving efficiency; the pressure sleeve system provides controlled fragment compression for enhanced fixation stability; screw holding tools include guiding sleeves for direct screw implantation and holding forceps for angular adjustment, accommodating different anatomical positions.
Efficient Closed-Loop Workflow Significantly Reduces Operative Time
The set enables seamless transition through the complete "guidewire positioning → drilling → depth measurement → tapping → screw placement → locking" workflow, dramatically reducing instrument change frequency. The φ1.1mm ball-tip guidewire serves dual purposes of positioning and temporary fixation, avoiding repeated penetration. The coaxial design of cannulated drills/taps with guidewires maintains procedural continuity, while quick-connect handles facilitate rapid T8 driver switching, combined with screw holding sleeves for immediate screw installation and locking.
Millimeter-Level Precision Control Substantially Lowers Surgical Risks
Dual-hole drill sleeves provide bipoint support, ensuring complete coincidence between drilling path and guidewire trajectory to prevent deviation; drill stoppers precisely set drilling depth, verified by depth gauges for effective prevention of joint surface or neurovascular structure penetration; φ1.0mm guidewire cleaners maintain bone channel patency and confirm pathway integrity, avoiding screw implantation jamming. The system's triple precision assurance mechanism significantly reduces risks of screw malposition, bone channel split, and nerve injury.
Ultimate Minimally Invasive Design Accelerates Patient Recovery
The φ2.0mm cannulated drill creates minimal bone windows, combined with ball-tip guidewire precision penetration, effectively reducing soft tissue damage; periosteal elevators enable extremely limited exposure while protecting tendons and nerve endings; continuous operation through cannulated instruments avoids repeated tissue dilation.
Broad Compatibility and Cost-Effectiveness
Compatible with 2.5mm/3.0mm ball-tip and double-end screws, covering 90% of hand/foot/pelvic minimally invasive fixation needs; safely applicable from pediatric epiphyseal fixation to osteoporotic patients, with cannulated design supporting intraoperative C-arm monitoring; the set integrates six surgical functions (guidance, drilling, depth measurement, tapping, screw placement, locking) in core tools, reducing hospital procurement and management costs.
