3.5/4.0/4.5mm Cannulated Screw Instrument Set

Wide clinical applicability with strong compatibility across diverse indications, seamlessly supporting procedures from simple metaphyseal fractures to complex joint fusions.

Supports advanced percutaneous procedures under fluoroscopy, reducing soft tissue stripping, minimizing periosteal damage, and lowering postoperative complication rates.

Provides exceptionally strong compression fixation. The lag screw principle creates excellent mechanical stability, preventing fracture shortening and ensuring reliable surgical outcomes.

Guide Wire Technique & Depth Measurement

Cannulated screws are inserted precisely over a K-wire under fluoroscopic guidance. The integrated depth gauge allows for highly accurate length measurement directly via the corresponding scale on the guide wire.

Sliding & Static Compression Fixation

The partially threaded design generates powerful interfragmentary compression as the screw is driven in. This promotes primary bone fracture healing and effectively prevents bone shortening.

Optimized Screw Thread Profile

Engineered with large-pitch cancellous threads to facilitate rapid screw insertion and removal, while simultaneously providing high resistance to pullout forces in osteoporotic bone.

Low-Profile Anatomy Adaptability

The low-profile screw head is meticulously designed to reduce the possibility of soft-tissue irritation. Available in 3.5mm, 4.0mm, and 4.5mm diameters with multiple lengths to address a massive variety of fracture patterns.
