Advanced 7.3 mm Cannulated Screw Fixation Instrument System
The Cannulated Screw Instruments Set 7.3 mm is a professional orthopedic implant system designed for high-strength fracture fixation in large bone structures. It is widely used in trauma and reconstructive orthopedic surgery for achieving stable interfragmentary compression using 6.5 mm and 7.3 mm cannulated screw systems.
This comprehensive set includes all essential instrumentation required for accurate and controlled screw placement, including cannulated drill bits, guide wires, protective sleeves, countersinks, taps, depth gauges, screwdrivers, and wire handling tools. The system ensures precise alignment and secure fixation in both percutaneous and open surgical approaches.
The instruments are engineered for high mechanical strength and surgical accuracy, allowing surgeons to work confidently in complex fracture cases such as pelvic fractures, tibial plateau injuries, intercondylar fractures, and slipped capital femoral epiphysis.
Manufactured from premium surgical-grade stainless steel (316L) and cobalt-chromium guide wires, the system offers excellent durability, rigidity, and resistance to deformation. All components are fully autoclavable and designed for repeated surgical use in demanding orthopedic environments.
The included instrument case with organized screw caddies ensures safe storage, efficient workflow, and quick access during surgical procedures.
