Abstract
The present device described herein is intended to effect the removal of an orthopedic prosthetic implant from the intramedullary cavity of the bone. The extraction device utilizes a clamping mechanism which can be tightly secured to the implant, particularly the neck of a femoral prosthetic component. The clamping mechanism is attached to an elongated member that contains two striking surfaces. A force applied to the striking surface(s) is transmitted to the prosthesis so as to extract the implant from the intramedullary cavity of a bone.
Claims19
A device comprising:
- an elongated member having a first end and a second end, the elongated member comprising substantially straight, rod-like first and third segments each having first and second ends, the first and third segments being connected by a substantially curved second segment at their second and first ends, respectively, wherein the second member offsets the elongated member in an anterior plane and a lateral plane;
- a first striking surface positioned on the second segment extending away from the elongated member;
- a second striking surface positioned on the third segment extending away from the elongated member;
- and
- a clamping mechanism positioned on the first segment, wherein the clamping mechanism includes a channel substantially perpendicular to a long axis of the first segment that is configured to engage a surgical prosthetic implant.
A device comprising:
- a rod;
- a first striking surface;
- a second striking surface;
- and
- a clamping mechanism configured to engage a surgical prosthetic implant.
A method of removing an orthopaedic prosthetic implant, the method comprising:
- attaching an extraction device on the prosthetic implant, the extraction device comprises:
- a rod;
- a first striking surface;
- a second striking surface;
- and
- a clamping mechanism configured to engage the prosthetic implant;
- securing the extraction device to the prosthetic implant by connecting the clamping mechanism to the prosthetic implant;
- and
- applying a force to the extraction device through at least one of the striking surfaces.
