Conmed Linvatec D8640 Concept GraFix Modular Ratcheting Handle 7-1/4"

Conmed Linvatec D8640 Concept GraFix® Modular Ratcheting Handle | 7-1/4" | Orthopedic

The Conmed Linvatec D8640 is a high-performance modular handle designed specifically for the Concept GraFix® and Infinity™ Knee Preservation Systems. This 7-1/4 inch ergonomic handle serves as the primary manual driver for the insertion and removal of biocomposite, bioabsorbable, and metal interference screws during cruciate ligament reconstructions. Featuring a sophisticated internal ratcheting mechanism and a "Quick-Connect" interface, the D8640 allows surgeons to switch between various hex drivers, taps, and dilators mid-procedure with a single hand, significantly enhancing operative efficiency.

Part of a fully modular platform, this handle is engineered to provide high-torque manual control while maintaining the tactile sensitivity required to seat interference screws without compromising graft integrity or bone tunnel walls.

Technical & Clinical Advantages

• Ergonomic Ratcheting Logic: The internal ratchet reduces the need for repetitive wrist regripping, allowing for smoother, faster screw advancement which is critical for maintaining proper graft tension during tibial or femoral fixation.

• Modular Versatility: Designed to interface seamlessly with a wide array of Concept GraFix attachments, including the D8626 (3.5mm Hex Driver) and D8637/D8638 (BioScrew Taps), providing a cost-effective alternative to multiple fixed-length drivers.

• Quick-Connect Efficiency: The intuitive locking collar allows for "blind" attachment of modular shafts, enabling the surgical assistant to swap instruments rapidly without the surgeon diverting their focus from the arthroscopic monitor.

• High-Torque Performance: The handle diameter and grip texture are optimized to deliver the necessary leverage for self-tapping screws in dense cortical bone while preventing hand slippage.

• Durable Construction: Built to withstand the high-torque stresses of orthopedic surgery and the rigorous decontamination protocols of the Sterile Processing Department (SPD).

Condition & Quality Assurance

• Status: Used – Good Clinical Condition (Signs of Use).

• Mechanical Integrity: The ratcheting mechanism has been bench-tested in forward, reverse, and neutral (fixed) positions to ensure crisp engagement and zero slipping under load.

• Surface Condition: Shows visible signs of professional wear consistent with clinical use, such as minor surface marks or sterilization staining. The quick-connect collar remains fully functional with a tight, secure fit.

• Expertise: With over 25 years of experience in orthopedic instrumentation, Primis Medical ensures that every modular component is inspected for performance and is "theatre-ready."

Shipping & Handling

• Secure Logistics: Shipped in protective packaging to ensure the internal ratcheting gears and locking collar remain calibrated and debris-free during transit.

• Fast Dispatch: Ships within 1 business day.
