OR Grade Hexagonal Screw Driver Bit – 3.5MM Hex Cannulated | Orthopedic Instrument

Precision Cannulated Engineering

The Surgiportal 3.5mm Hex Bit is an essential component for complex internal fixation. The cannulated (hollow) design is meticulously engineered to slide over a guide wire (K-wire), ensuring that the screwdriver remains perfectly axial to the screw during insertion. This eliminates the risk of screw migration or misalignment, which is critical when performing percutaneous fixations or working in deep anatomical corridors.

High-Torque 3.5mm Hexagonal Profile

The 3.5mm hex interface is the clinical standard for large-fragment fixation hardware.

• Maximum Power Transfer: The hexagonal geometry allows for high-torque delivery without “cam-out,” ensuring screws are seated firmly in dense cortical bone.

• Reduced Stripping: Precision-milled tolerances between the bit and the screw head prevent rounding of the hex recess, maintaining the integrity of the implant for potential future removal.

• Universal Compatibility: Designed to fit industry-standard quick-coupling handles and power tool adapters used in orthopedic theaters.

OR-Grade Durability and Materials

Orthopedic procedures involve significant rotational forces. Forged from hardened, surgical-grade stainless steel, this bit is designed to withstand high torque without twisting or deformation. The material is resistant to wear, ensuring the 3.5mm hex profile maintains its sharp edges through hundreds of uses. A matte satin finish is applied to minimize glare from high-intensity operating room lights.

Reliable & Sustainable

As a fully autoclavable and reusable instrument, the Surgiportal Cannulated Bit offers a durable, professional-grade solution for orthopedic trauma units. Its smooth internal lumen and seamless external construction allow for thorough cleaning and sterilization, adhering to the strictest infection control protocols for bone surgery.

Technical Specifications

FAQs

1. What diameter guide wire is compatible with this 3.5mm cannulated bit?

This bit is designed to accommodate the standard guide wires typically used with 4.5mm and 6.5mm cannulated screw sets. Please verify the wire diameter against the internal lumen specifications to ensure a smooth slide-fit.

2. Can this bit be used with power drivers?

Yes. The bit features a standard quick-coupling end, making it fully compatible with the vast majority of orthopedic power drivers as well as manual ratcheting handles.

3. How do I maintain the internal cannula?

After each procedure, the internal lumen should be flushed with an enzymatic cleaner and scrubbed with a specialized thin wire brush. This is vital to ensure no bone marrow or biological debris is trapped before the sterilization process.
