Abstract
An orthopedic impacting tool comprises a motor, an energy storage chamber, a striker, and an anvil. The motor stores energy in the energy storage chamber and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.
Claims7
An orthopedic impacting tool for striking an object, the tool comprising:
- a motor;
- a linear motion converter;
- an energy storage means;
- a detent;
- a control means;
- an adapter, said adapter capable of holding a broach, chisel or other surgical implement;
- and
- a striker, said striker capable of impacting at least two distinct impact surfaces, wherein a first impact surface moves said adapter forward and a second impact surface moves said adapter rearward,
- wherein said control means directs said motor to store an energy in said energy storage means and said energy storage means thereafter releases the energy onto said striker causing said striker to move from a first position to a second position such that said striker is capable of imparting a force upon said adapter in a direction that is dependent at least in part on which surface said striker impacts.
