Deflectable finger connection feature on surgical saw blade

摘要

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.

主权项

1. A method of attaching a blade to a hand-held surgical tool, the method comprising:
opening a collet fixture of the hand-held surgical tool to create a space for reception of a proximal end of the blade; introducing a shank of the collet fixture into a first opening having a slot at the proximal end of the blade, wherein the first opening and slot is defined at least partially by one or more fingers at the proximal end of the blade, wherein the introducing of the shank comprises deflecting the one or more fingers with the shank into one or more corresponding gaps formed within the first opening and slot from a first state to a second state; and advancing the shank into the first opening and radially beyond ends of the one or more fingers, such that the one or more fingers return to the first state after deflecting within the one or more corresponding gaps formed within the first opening and slot, wherein while the one or more fingers are in the first state and the shank is in the first opening and slot, the blade is provisionally secured to the shank by at least the one or more fingers.
