Abstract:
1. A saw blade assembly for use with a driver having an oscillatory drive member for performing surgical cuts to bone tissue with minimal injury to surrounding tissue, said saw blade assembly comprising: an elongate sheath having a proximal end, a distal end, a first side, an opposing second side, an open interior defined between the first side and the second side, and an aperture through one of the first side and the second side, said proximal end being removably mountable on the driver to be held stationary relative to the driver when said saw blade assembly performs surgical cuts; an elongate monolithic blade received within the open interior of the sheath, said monolithic blade having a unitary construction, with no moveably connected parts, a central longitudinal axis, a proximal end that extends through the aperture of the elongate sheath to removably couple to the oscillatory drive member of the driver when the proximal end of the elongate sheath is mounted on the driver, a single pivot point located at the proximal end, a first side, an opposing second side, and a distal cutting end transverse to the central longitudinal axis and extending from the distal end of the sheath; wherein the first side of the blade faces the first side of the sheath and the second side of the blade faces the second side of the sheath; wherein a majority of the blade is housed within the interior of the sheath, wherein the sheath has no moving internal parts other than the elongate monolithic blade; and wherein the oscillatory drive member pivots the distal cutting end back and forth about the pivot point at the proximal end of the monolithic blade when the proximal end of the monolithic blade is coupled to the oscillatory drive member to perform surgical cuts.
