Synthes Conical Extraction Screw | 1.5mm & 2.0mm Compatibility | 309.510

The Synthes 309.510 is a specialized salvage instrument engineered for the removal of compromised 1.5mm and 2.0mm cortex screws. This tool is a critical component of the Synthes Broken Screw Extraction Set, designed for scenarios where the screw head is stripped, damaged, or the internal drive is otherwise inaccessible with standard screwdrivers.

Featuring a precision-tapered conical design with sharp, reverse-cutting threads, this instrument is designed to bite into the inner lumen or the periphery of a screw head. By applying counter-clockwise torque, the extraction screw wedges itself into the damaged screw, creating a high-friction mechanical lock that allows the surgeon to back the screw out safely.

Key Specifications

• Manufacturer: Synthes (DePuy Synthes)

• Model / REF: 309.510

• Material: Surgical Grade Stainless Steel

• Compatibility: 1.5mm and 2.0mm Cortex Screws

• Design: Conical, Reverse-Threaded Taper

• Coupling: Small Quick Coupling (QC)

• Quantity: 1 Each

Technical & Clinical Advantages

• Optimized for Micro-Fragments: Specifically calibrated for the small internal diameters of 1.5mm and 2.0mm screws. The taper is engineered to engage without shattering the delicate heads of small fragment hardware.

• Reverse-Thread Engagement: The cutting flutes are oriented in a left-hand (counter-clockwise) direction. As the surgeon turns the extractor to remove the screw, the instrument drives itself deeper into the metal, increasing the grip as resistance increases.

• Preservation of Bone Stock: By providing a direct extraction path, the 309.510 minimizes the need for aggressive bone removal around a stuck screw (e.g., via hollow reamers), which is critical in delicate hand, foot, and cranio-maxillofacial surgeries.

• Quick Coupling Interface: Designed for use with manual T-handles or small quick-connect handles, providing the tactile feedback necessary to feel the metal-on-metal engagement without over-torquing.

• Durable Construction: Forged from high-strength stainless steel to ensure the cutting flutes maintain their sharpness, even when biting into cold-welded or damaged titanium or stainless steel implants.

Applications

• Hardware Removal: Extracting old or damaged hardware during revision surgeries.

• Broken Screw Salvage: Removal of screws where the hexagonal or cruciform drive has been "cammed out" or stripped by excessive torque.

• Cranio-Maxillofacial & Hand Surgery: Precise removal of small fragment screws in delicate anatomical regions where standard extraction methods are too high-risk.
