Synthes 5.0 mm Cannulated Drill Bit | Large Quick Connect | 310.63 The Synthes 310.63 is a specialized orthopedic instrument engineered for high-precision bone preparation, particularly in large-fragment fixation. With a 5.0 mm diameter and an internal 2.9 mm cannulation, this bit is designed to track accurately over guide wires (K-wires), ensuring the concentric alignment required for the subsequent placement of 6.5 mm and 7.3 mm cannulated screws. Measuring approximately 300 mm (11-3/4 inches), the 310.63 provides the extended reach necessary for deep anatomical sites, such as the femoral neck, calcaneus, or periprosthetic fractures, where standard-length bits may fall short. Key Performance Features Cannulated Precision (2.9 mm ID): The internal lumen is specifically calibrated to slide over a standard guide wire. This "path-following" design is critical for percutaneous and minimally invasive techniques, preventing bit "walking" and ensuring the screw trajectory remains perfectly centered. Extended Reach (300 mm): The 11-3/4 inch profile allows surgeons to maintain clear visibility and control when working in deep or confined anatomical zones, or when drilling through significant soft-tissue envelopes. Large Quick-Connect Interface: Specifically engineered for the Synthes Large Quick Coupling system. This allows for rapid, one-handed attachment and removal from power drivers, reducing operative time and improving surgical flow. Optimized Flute Geometry: Designed to efficiently evacuate bone debris (swarf) through the extended shaft, reducing heat buildup and the risk of thermal necrosis during deep-channel drilling. High-Grade Surgical Steel: Manufactured by Synthes to withstand the high torque requirements of large-fragment orthopedic trauma and reconstructive surgery. Technical Specifications Manufacturer: Synthes Product Code: 310.63 Drill Diameter: 5.0 mm Cannulation Diameter: 2.9 mm Overall Length: 300 mm (11-3/4") Shank Type: Large Quick Connect (QC) Compatibility: 6.5 mm and 7.3 mm Cannulated Screw Sets Clinical & Institutional Advantages Improved Implant Accuracy: By tracking over a pre-placed guide wire, the 310.63 minimizes the risk of cortical breakout, which is essential when placing screws in the narrow corridors of the pelvis or femoral neck. Procedural Versatility: The large quick-connect shank is compatible with most standard orthopedic power systems (System 6, 7, and 8), making it a versatile addition to any trauma or total joint tray. Sustainable Procurement: Utilizing a "Used-SI" Synthes component allows facilities to maintain high-specification OEM standards for their trauma sets while achieving significant cost savings. Ideal Applications Hip Surgery: Cannulated screw fixation for femoral neck fractures. Trauma: Slipped Capital Femoral Epiphysis (SCFE) pinning and complex pilon fractures. Hindfoot Procedures: Subtalar and calcaneal arthrodesis. Long Bone Fixation: Targeted drilling for intramedullary nail interlocking bolts. Condition & Quality Assurance Status: Used Surgical Instrument (USED-SI). Integrity: Shows visible signs of wear consistent with prior clinical use. The cannulation is clear and patent; the quick-connect shank and cutting flutes remain in usable condition for continued medical procedures. Reprocessing Note: As a used surgical instrument, this item must undergo standard hospital cleaning and sterilization (autoclave) protocols prior to clinical use. It is recommended to inspect the cutting edges for sharpness as part of standard pre-operative tray assembly.
