FEMORAL CUP OR FEMORAL BALL EXTRACTOR |
摘要 |
A surgical instrument for separating a femoral cup or a femoral ball from a femoral implant wherein the cup or ball is affixed to the implant by means of a Morse taper. A tapered wedge in the form of a two pronged fork is provided at the distal end of the instrument for placement between the cup or ball and the femoral implant. Then the proximal end of the instrument is struck with a hammer to separate the cup or ball from the femoral implant. The surgical instrument of the invention enables a surgeon to remove the cup or ball without pulling on the femoral implant and, thereby, without disrupting any bone ingrowth in the implanted femoral implant. |
