Surgical sagittal saw for actuating an oscillating blade head, the saw having an oscillating drive member capable of translation motion

Abstract From the Canadian patent

A surgical sagittal saw with an indexing head. The saw actuates a blade assembly that includes a bar from which a blade head extends. An oscillating head extends upwardly from the saw head. The oscillating head in addition is mounted to the saw head to be able to rotate around its longitudinal axis and so that it can move along the saw head. A biasing spring normally holds the oscillating head in a fixed position. When the oscillating head is in the fixed position the oscillating head holds the blade assembly against a restraining bracket integral with the saw head. Manual force is used to overcome the biasing spring to allow replacement and removal of the blade assembly.
