Abstract

The invention is a percussor comprising an anvil, a hammer, a coil, and a pulse generator. The anvil is equipped with a force-receiving surface and a force-delivering surface which are rigidly connected together, the force-delivering surface being intended for contact with a patient'"'"'s body. The hammer is also equipped with a force-receiving surface and a force-delivering surface, the hammer being attached to the anvil in such a way that the hammer'"'"'s force-delivering surface and the anvil'"'"'s force-receiving surface are mechanically free to come together or move apart. The coil forces the hammer'"'"'s force-delivering surface and the the anvil'"'"'s force-receiving surface to separate when the coil is energized with an electrical current. The pulse generator supplies repeated electrical current pulses to the coil which causes repeated impulse forces to be applied to a patient'"'"'s body whenever the technician applies a continuing force to the hammer'"'"'s force-receiving surface.

Claims

1. A percussor comprising:

an anvil having a force-receiving surface and a force-delivering surface which are rigidly connected together, the force-delivering surface being intended for contact with a patient'"'"'s body;

a hammer having a force-receiving surface and a force-delivering surface, the hammer being attached to the anvil in such a way that the force-delivering surface of the hammer and the force receiving surface of the anvil are mechanically free to come together or move apart;

a coil which forces the force-delivering surface of the hammer and the force-receiving surface of the anvil to separate when the coil is energized with an electrical current;

a pulse generator which supplies repeated electrical current pulses to the coil.

2. The percussor of claim 1 wherein a force applied to the force-receiving surface of the hammer causes the force-delivering surface of the hammer to contact the force-receiving member of the anvil when the pulse generator is not supplying an electrical current pulse to the solenoid.

3. The percussor of claim 1 wherein a force applied to the force-receiving surface of the hammer does not cause the force-delivering surface of the hammer to contact the force-receiving member of the anvil when the pulse generator is supplying an electrical current pulse to the coil and the force applied is less than the maximum force for which the percussor is designed to handle.

4. The percussor of claim 1 wherein the coil is attached to the anvil.

5. The percussor of claim 1 wherein the coil is attached to the hammer.

6. The percussor of claim 1 wherein the anvil comprises a member made of a magnetic material.

7. The percussor of claim 1 wherein the hammer comprises a member made of a magnetic material.
