An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.

1. An orthopedic impacting tool for striking an object, the tool comprising: a motor based drive assembly;a compression piston operatively coupled to said motor based drive assembly, said compression piston having a first end and a second end;an air chamber, said air chamber comprising a forward portion and a rear portion, wherein said forward portion is proximate to said first end of said compression piston, andsaid rear portion is proximate to said second end of said compression piston;an impacting element;a control unit;an anvil element with a front face and a rear face, said anvil element adapted to accept a portion of a broach adapter, the broach adapter capable of holding a broach, chisel, reamer, or other surgical implement,said broach adapter operatively coupled to said anvil element and being proximate to said first face of the anvil element and distal to said second face of said anvil element; anda hand grip;wherein said control unit directs said motor based drive assembly to cause said compression piston to move and compress air within said front portion of said air chamber or compress air within said rear portion of said air chamber, and wherein said impacting element cyclically impacts said front face of said anvil element upon application of compressed air from the front portion of said air chamber, andwherein said impacting element cyclically impacts said rear face of said anvil element upon application of compressed air from the rear portion of said air chamber,such that the impacting element is capable of imparting a force upon the broach adapter in at least one direction. 2. The tool of claim 1, wherein said motor based drive assembly includes a linear motion converter which comprises a slider crank mechanism. 3. The tool of claim 2, wherein said motor based drive assembly comprises a voice coil motor. 4. The tool of claim 1, wherein the control unit allows for single percussive impacting. 5. The tool of claim 1, wherein said tool further comprises a lighting element disposed on an exterior surface of the tool, said lighting element operatively coupled to the control unit. 6. The tool of claim 1, wherein a velocity of said impacting element is controlled by a speed at which the air is compressed or decompressed. 7. The tool of claim 1, wherein the tool comprises a positional sensor that is operatively coupled to one of the control unit of the tool or the motor based drive assembly of the tool, the positional sensor to determine whether the tool is being pushed toward the object or pulled away from the object,which the positional sensor causes said control unit or motor based drive assembly of the tool to direct the impacting element to impart a greater force upon said front face of said anvil element and a lesser force on said rear face of said anvil element upon sensing that the tool is being pushed toward the object, andwhich the positional sensor causes said control unit or motor based drive assembly of the tool to direct the impacting element to impart the lesser force upon said front face of said anvil element and the greater force on said rear face of said anvil element upon sensing that the tool is being pulled away from the object. 8. The tool of claim 1, wherein said tool comprises a torsion sensor, which torsion sensor is capable of determining a lateral movement of the tool and which sensor is capable of signaling such movement. 9. The tool of claim 1, wherein said broach adapter has an adjustment to offset the attached broach, chisel, reamer, or other surgical implement from a central axis of the tool while maintaining a parallel orientation of the broach, chisel reamer, or other surgical implement with respect to the central axis of the tool. 10. The tool of claim 1, wherein said broach adapter comprises a parallel four-bar mechanism.
