Abstract

The invention belongs to the technical field of medical treatment and particularly discloses a manufacturing process for a surface replacement femoral head and the femoral head. The femoral head comprises a femoral handle and a femoral head body, wherein a replacement fixed cavity pointing to the femoral handle is formed inside the femoral head body, a replacement cut surface is polished on the surface of the femoral head body, a replacement femoral head surface is fixedly mounted on the surface of the replacement cut surface and comprises a replacement surface and an insertion rod, the replacement surface is in tight fit with the replacement cut surface, a fitting cavity in fit with the femoral head body is formed inside the replacement surface, and the insertion rod is arranged between the interior of the fitting cavity and the middle part of the replacement surface. According to the manufacturing process and the femoral head, the femoral head is scientific and reasonable and is safeand convenient in use; and a replacement prosthesis is improved and is composed of the replacement surface and the insertion rod, the replacement surface can be manufactured by using a forging process, the strength and wear resistance of the replacement surface are improved, the insertion rod can be manufactured and produced by using any manufacturing process, and the cost of production manufacturing is reduced.
