Surgical sagittal saw with blade connection assembly that does not require tools to operate indexing head and oscillating tip saw blade, and oscillating tip saw blade with self-cleaning head

摘要

A surgical saw blade is described comprising an elongated blade bar having opposed plates. The blade bar has opposed proximal and distal sections, with the proximal section having a feature for releasably holding the blade bar to a powered surgical sagittal saw. The blade bar plates are spaced apart from each other so as to form in the blade bar distal section a void space and a primary opening into the void space. A blade head of the surgical saw blade has a base disposed in the blade bar distal section opening that is pivotally mounted in the blade bar distal section void space, and a crown integral with the base that extends through and outside of the blade bar distal section primary opening, the crown being formed with teeth, wherein a thickness of the crown is greater than a thickness of the base to allow the insertion of the blade bar into a kerf cut by the blade head. At least one drive rod is provided and adapted to pivot the blade head. The blade head base is formed with a through window and a support member extends between the blade bar plates through the void space defined by the plates and through the blade head base window.
