US 11,779,468 B2 · Implant extractor

Abstract

An implant extractor including a shaft body and a telescoping push rod extending from the shaft body. An adjustor is engaged with the telescoping push rod for adjusting a length of the telescoping push rod. A support arm extends laterally away from the shaft body and a jaw assembly extends from the support arm. The jaw assembly includes a jaw moveable between a locking position and an unlocking position, and a rocker arm operatively engaged with the telescoping push rod and the jaw. The implant extractor provides a line of force spaced from and substantially parallel to an implant to be extracted. As a consequence, there is substantial clearance for an extension handle such as a C-frame or the like which is oftentimes needed to dislodge the implant from surrounding bone. In addition, the implant extractor is capable of gripping a wide range of sizes of hip stem implant trunnions.
