Implant removal tool
An implant removal tool ( 1 ) used to remove a femoral implant ( 17 ) from a femur bone ( 18 ) by providing a substantially U-shaped body ( 2 ) having a substantially rectangular-shaped opening ( 9 ) located thereon that allows the substantially U-shaped body to be placed over a neck ( 21 ) of a femoral implant so a sharpened front edge ( 5 ) of the substantially U-shaped body makes direct contact with an inner surface of the stein of the femoral implant. The U-shaped body may have front side edges ( 26, 27 ) that extend beyond a front edge ( 5 ) to allow the front side edges to cut anterior and posterior surface of the implant.
1. An implant removal tool comprising:
a substantially U-shaped body having a curved inner surface, a curved outer surface, a front edge, a right side edge, a left side edge and a rear surface;
wherein the right side edge transitions to the sharpened front edge by a front right side edge, and the left side edge transitions to the sharpened front edge by a front left side edge; and
wherein the front edge is configured for cutting;
wherein the curved inner surface defines an interior space;
an attachment means located on the substantially U-shaped body; and
an opening located within the substantially U-shaped body between the right side edge and the left side edge;
wherein the opening has an opening front edge, an opening rear edge, an opening right side edge and an opening left side edge, and is shaped to accommodate a femoral implant stem to pass through;
wherein the opening has a width substantially equal to a width of the interior space.
2. The implant removal tool of claim 1 , wherein the front edge of the substantially U-shaped body is sharpened.
3. The implant removal tool of claim 1 , wherein the opening front edge is curved.
4. The implant removal tool of claim 3 , wherein the attachment means is a threaded member.
5. The implant removal tool of claim 1 , wherein the front right side edge and the front left side edge each forms a triangular-shaped point.
6. The implant removal tool of claim 1 , wherein the front right side edge and the front left side edge are each sharpened.
7. The implant removal tool of claim 1 , wherein the attachment means is a threaded member.
8. The implant removal tool of claim 1 , wherein
the front right side edge and the front left side edge extend beyond the front edge away from the attachment means.
9. The implant removal tool of claim 8 , wherein the front right side edge and the front left side edge each forms a triangular-shaped point.
10. The implant removal tool of claim 8 , wherein the front right side edge and the front left side edge are each sharpened.
11. The implant removal tool of claim 1 , wherein the attachment means is a handle.
12. The implant removal tool of claim 1 , wherein the opening front edge is curved to conform to a femoral implant.
13. The implant removal tool of claim 1 , wherein the opening right side edge and the opening left side edge have a length equal to a height of the upper portion of a femoral implant to be removed.
