Adjustable surgical blade

A cutting blade for use with an oscillatory cutting saw having a blade retention device such as an oscillatory cutting saw used to surgically cut bone, the cutting blade comprising:

• (a) a central cutting blade shank having a longitudinal axis;
• (b) a distal end having a plurality of cutting teeth disposed substantially on a tangent perpendicular to the longitudinal axis of the cutting blade shank;
• and
• (c) a proximal end having a plurality of spaced-apart attachment elements, each of said attachment elements being capable of cooperating with the blade retention device so as to firmly attach the blade to the oscillatory cutting saw;
• whereby the attachment of the blade to a oscillatory cutting saw by one of the attachment elements results in a distance between the cutting teeth and the blade retention device which is different from the distance between the cutting teeth and the blade retention device resulting from the attachment to the oscillatory cutting saw by a different attachment element.

A cutting blade for use with an oscillatory cutting saw having a blade retention device such as an oscillatory cutting saw used to surgically cut bone, the cutting blade comprising:

• (a) a central cutting blade shank having a longitudinal axis;
• (b) a distal end having between about 6 and about 16 teeth disposed substantially on a tangent perpendicular to the longitudinal axis of the cutting blade shank, each tooth being shaped substantially as a right triangle;
• and
• (c) a proximal end having a plurality of pairs of opposed notches, each of the notches being capable of cooperating with the blade retention device as to firmly attached the blade to the oscillatory cutting saw;
• wherein the attachment of the blade to an oscillatory cutting saw by a pair of the opposed notches results in a distance between the cutting teeth and the blade retention device which is different from the distance between the cutting teeth and the blade retention devices which results from the attachment to the oscillatory cutting saw by a different pair of opposed notches.
