The 7" Bone File DE #12 5mm is a surgical instrument designed for refining and smoothing bone surfaces during orthopedic procedures. The 7" length provides the surgeon with adequate reach and control, especially for working in deeper or more difficult-to-access areas. The #12 designation refers to a specific file pattern, which is often used for finer bone filing, and the 5mm size indicates the width of the working surface, suitable for precise shaping of bone in smaller or more confined areas.
