Abstract
An orthopedic surgical instrument or impactor is disclosed. The surgical instrument being configured to provide a first forward energy or motion to drive a surgical tool (e.g., a broach, a rasp, a cutting tool, etc.) and/or an orthopedic implant (e.g., an intramedullary nail, a stem, etc.) into a patient's bone and a second reverse energy or motion to, for example, remove a stuck or lodged surgical tool or implant from a patient's bone. In one embodiment, the surgical instrument incorporates dual springs and dual masses (impactors) to store and release energy on demand to deliver an impact force in both forward and reverse directions. In one embodiment, the surgical instrument may also include a forward energy adjuster and a reverse energy adjuster so that a user can independently adjust the amount of energy provided in the forward and reverse directions as well as a means to adjust impact frequency.
