Abstract
A device for extracting an implant from a bone. The device has a handle that extends from a proximal end to a distal end. A pair of opposable jaws operatively associates with the distal end in such a way to move between an open position and a closed position. The first and second jaws of the pair of opposable jaws each have an arrangement of osteotome blades that align with an interfacing surface of the implant. The osteotome blades engage the jaws so as to move between a retracted position and an inserted position occupying space between the interfacing surface and the bone. A slide hammer is operatively associated with the proximal end of the handle for urging the implant linearly away from the bone with the jaws in the closed position and the osteotome blades in the inserted position.
Claims10
A device for extracting an implant, the implant having an interfacing surface engaging a bone, the device comprising:
- a handle;
- a first and second jaw opposably associated with a distal end of the handle in such a way to move between an open position and a closed position engaging opposing edges of the implant;
- and
- for each jaw, an arrangement of blades aligned with the interfacing surface in the interfacing surface in the closed position, wherein each blade of the arrangement of blades is movable between a retracted position and an inserted position, wherein the arrangement of blades occupies space between the interfacing surface and the bone.
