ABSTRACT:
A collet for attaching a blade to a surgical saw is biased toward a closed position in which the blade is securely clamped between a drive member and a clamping member. A rotational movement of a knob is converted into a translational movement of the clamp to open the collet. A mechanism is provided for maintaining the collet in the open position for simplified operation and cleaning.
