Abstract
The surgical saw blade and hub of this invention includes a saw blade and instrument hub which connect the saw blade to the instrument such that no portion of the instrument extends beyond the blade. The blade includes a washer having a plurality of radially extending slots in communication with the central bore of the washer. Alternating slots of the washer are truncated or otherwise do not fully extend through the washer. The truncated slots form shoulders or lans within the washer. The center opening of the washer is in alignment with a base opening in the blade and accommodates a hub from the powered instrument. The hub of the powered instrument includes a plurality of radial fins extending outwardly therefrom. The fins abut against the shoulders of the washer to lock the blade to the hub. A helical spring is provided to maintain pressure against the blade and thereby retain the blade and hub in a locked configuration.
