Claim 9:
10. A rotary impacting tool for orthopedic surgery, the tool comprising
a housing,
a motor,
an impact hammer,
an output anvil,
a lead screw element, and
an energy storage means, wherein the energy storage means is proximate to the impact hammer for a portion of an operational cycle of the tool,
wherein the impact hammer is disposed on the lead screw element and is rotated by the motor, and wherein the impact hammer is in contact with the output anvil to cause the output anvil to rotate selectively, wherein upon the output anvil ceasing rotation, the impact hammer translates along the lead screw element to energize the energy storage means, and wherein after the impact hammer has translated a sufficient distance away from the output anvil, the energy storage means imparts its energy on the impact hammer causing the hammer to accelerate along the lead screw element and rotationally impact the output anvil.
