Claim 18:
19. A surgical instrument for the dissection of bone or other tissue, the surgical instrument comprising:
a mass spring oscillator having an alternating rotational output;
a tool having a shaft with a dissection area disposed adjacent a distal end and a coupling area disposed adjacent an opposite proximal end; and
a coupling assembly configured to selectively couple the alternating rotational output to the coupling area of the tool in a run position, the coupling assembly defining an attachment aperture extending from a first end to a second end along a length of the coupling assembly, the attachment aperture configured to receive the coupling area of the tool on the first end, the attachment aperture configured to receive a portion of the mass spring oscillator on the second end, the coupling assembly including an unlock position wherein the tool is decoupled from the alternating rotational output, the coupling assembly further including an actuator for controlling movement of the coupling assembly from the run position to the unlock position.
