OG exemplary drawing
 
1. A surgical saw for use with a blade assembly having a blade bar, at least one elongated body moveably disposed within the blade bar and a blade head that is oscillated by the at least one elongated body, the saw comprising:
a housing including a head, the head defining a surface for receiving the blade bar of the blade assembly;
a motor;
a drive assembly including an oscillating head that is moveably mounted to the head adjacent the surface on which the blade bar is received, wherein the drive assembly is connected to the motor such that upon actuation of the motor, the drive assembly oscillates the oscillating head; and
a blade coupling assembly separate from the drive assembly that is moveably mounted to the head of the housing so as to extend above the surface of the head, the blade coupling assembly including a coupling rod configured to extend through an opening in the blade bar and shaped to extend at least partially over the blade bar moveable between a run state where the blade coupling assembly presses the blade bar to the surface of the head and a load state where the blade coupling assembly allows the insertion and removal of the blade bar from the surface of the head.
