An orthopedic impacting tool including a motor, an energy storage chamber, astriker (25, 34), and an anvil (14). Themotor stores energy in the energy storage chamber and then releases it,causing the striker to apply a controlled force on an adapter(1) to create a precise impact for use in a surgical setting. The tool mayfurther comprise a combination anvil and adapter. Alternatively,the tool may comprise a gas spring assembly system (32, 46, 40) for generatingan impact force. The tool further allows forwardor backward impacting for expanding the size or volume of the opening or forfacilitating removal of a broach, implant, or othersurgical implement from the opening. An energy adjustment control of the toolallows a surgeon to increase or decrease the impactenergy. A light source and hand grips improve ease of operation of the tool.
