This specialized instrument set is designed for the safe and efficient implantation of 3.5mm and 4.0mm headless cannulated screws in minimally invasive orthopedic procedures.
The system includes 13 core tools that address the technical essentials of small-incision surgery, precise positioning, and bone channel preparation, covering the complete workflow from accurate guidance, graded reaming, and depth measurement to secure screw implantation and maintenance.
Manufactured from high-strength stainless steel with precision engineering, critical components (e.g., tapered drill bits) undergo optimized treatment to ensure smooth operation and clear radiographic visibility in limited exposure scenarios.
With a design philosophy centered on "Precise Guidance + Graded Preparation + Secure Implantation," the system utilizes unique tapered drill bits, depth-sensing protection mechanisms, and quick-connect systems to achieve minimally invasive implantation of headless cannulated screws in periarticular fractures (e.g., wrist, ankle) and small fragment fixation.
Compared to traditional solid screws, it significantly reduces bone loss and meets diverse clinical needs for intra-articular fracture fixation, subchondral bone support, ligament attachment reconstruction, and precise reduction of small fragments.
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 Positioning and Safe Guidance
The system core relies on fine 1.3mm guidewires for initial accurate positioning, establishing a precise directional foundation for screw implantation. Combined with dedicated guidewire sleeves and drill sleeves, it effectively isolates and protects surrounding soft tissues, significantly reducing risks of guidewire deviation or soft tissue entanglement in minimally invasive small-incision procedures, ensuring operational safety and clear imaging guidance in limited exposure conditions.
Gradual Progressive Bone Channel Preparation
For different bone quality conditions and screw sizes (3.5mm/4.0mm), the set provides a unique combination of tapered cannulated drills and standard cannulated drills. This graded design allows surgeons to perform progressive, low-trauma bone channel expansion. The tapered drill bit optimizes cutting efficiency and reduces bone loss, while standard drills complete final aperture matching, achieving efficient, smooth bone channel preparation with significantly less bone loss compared to traditional solid screws.
Secure Implantation and Convenient Operation Loop
The set includes a comprehensive screw implantation and tool chain. Depth gauges accurately measure bone channel depth to prevent screw penetration. SW2.0/SW2.5 cannulated hex drivers precisely match the drive interfaces of different headless screw specifications, with their cannulated design ensuring final screw implantation under continuous guidewire guidance. Quick-connect handles provide rapid connection and labor-saving insertion. Screw holding forceps ensure stability and precision during screw passage and initial insertion. Dedicated guidewire cleaners maintain the patency and reusability of core guidance tools, forming a complete, efficient, and secure implantation operation loop from measurement, driving to maintenance, meeting the high-precision requirements of intra-articular and small fragment fixation.
Significantly Reduced Bone Loss and Soft Tissue Damage
The core advantage lies in maximizing protection of bone tissue and surrounding soft tissues. Fine 1.3mm guidewires enable precise initial positioning, while dedicated guidewire sleeves and drill sleeves effectively isolate soft tissues, substantially reducing intraoperative entanglement or collateral damage risks. The critical graded progressive bone channel preparation approach (tapered/standard cannulated drill combination) allows gradual bone channel expansion with minimal trauma, significantly reducing bone loss compared to traditional solid screw implantation methods—particularly suitable for fragile bone areas (e.g., periarticular regions, subchondral bone) and small fragment fixation, effectively maintaining bone structural integrity.
Precise Implantation Ensures Surgical Safety and Reliability
The set provides full-process precision control mechanisms to ensure accurate screw positioning, controlled depth, and reliable fixation. Depth gauges offer precise depth measurement, effectively preventing screw penetration into joint surfaces or cortical bone, serving as core safety assurance. SW2.0/SW2.5 cannulated hex drivers perfectly match headless screw drive interfaces, with their cannulated design ensuring final insertion under continuous guidewire guidance, avoiding directional deviation during implantation. Screw holding forceps ensure stability during passage and initial fixation, providing a solid foundation for precise implantation. This multiple保障 system significantly reduces surgical risks and enhances fixation outcome predictability.
Efficiency and Convenience Optimize Surgical Workflow
The set design highly aligns with clinical operational logic, significantly improving surgical efficiency and surgeon experience. Quick-connect handles allow rapid connection and efficient screw insertion, saving operative time and reducing operator fatigue. The instrument combination (guidewires, drills, drivers, depth gauges, holding forceps) forms a seamlessly connected operational loop, reducing intraoperative tool change frequency and time. Dedicated guidewire cleaners ensure patency of core guidance tools (1.3mm guidewires), guaranteeing reusability and improving instrument utilization efficiency. The overall design optimizes the entire workflow from positioning, drilling, depth measurement to screw implantation, making surgical operations smoother and less labor-intensive.
Economic Practicality Balances Performance and Maintenance
While ensuring high performance, the set demonstrates practicality and economy. Instruments are manufactured from high-strength stainless steel with specially treated critical components, ensuring durability and long-term reliability. Modular design facilitates easy cleaning, sterilization, and maintenance. The inclusion of guidewire cleaners specifically maintains core 1.3mm guidewires, extending the service life of high-value consumables and reducing per-procedure instrument costs. The organized set components (including instrument case) facilitate easy access and inventory, enhancing operating room management efficiency.
