WIPO Patent Application WO/2010/075774
Kind Code:
A1
Abstract:
A replacing module for femoral head has a cover body (31, 34) including two concave parts (311) extending in opposite directions, and a combined part (313) extending outwardly in bulgy manner. The concave part (311) is provided with a base section (3111) and a top section (3112). The shape and size of an inner surface of the base section (3111) are obtained by scanning a collum femoris surface of a patient with a medical stereo scanner. The shape and size of an inner surface of the top section (3112) is shaped on the basis of a cut closed curve that is connected by the points on the perimeter of the collum femoris surface closest to the central axis, so that the top section (3112) can be tightly sleeved on a bump part that is cut on the collum femoris of the femur correspondingly to form a tight combination and location between the inner surface of the cover body (31, 34) and the collum femoris surface. An artificial femoral head (5, 33) is sleeved and fixed on the combined part (313) of the cover body (31, 34). Surgical tools for replacing femoral head are also provided.
