Abstract

A surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw includes a distal portion comprising a plurality of cutting teeth, a shank portion adjacent the distal portion, and a proximal portion adjacent the shank portion. The proximal portion may include a longitudinally extending slot having a proximal opening. The slot may be shaped to receive a portion of the surgical saw through the proximal opening. The proximal portion may have a plurality of deflectable fingers respectively separated from a plurality of main body portions by respective gaps. The plurality of deflectable fingers may extend adjacent the longitudinally extending slot, and may deflect into the gaps to increase and decrease a width of a portion of the slot.
