The invention discloses a femoral head replacement module and a surgical tool. The surgical tool comprises a cutting die sleeve and a die cutter, wherein cutting die sleeve is a hollow shell with the shape identical to the shape of the surface of a femoral neck and can be easily and closely sleeved on the periphery of the femoral neck, so that the die cutter can cut the end of the femoral head tobe replaced into a preset anatomical section shape and can be conveniently removed after surgery, the top side of the cutting die sleeve is provided with a catheter so as to drill a central hole on the femoral head, the middle section of the cutting die sleeve is transversely provided with a horizontal channel for precise guide during the removal of the femoral head; a femoral head replacement module at least comprises a shield and an artificial femoral head, wherein the base end of the shield is formed to be identical to a surface with the thickness identical to the thickness of the part below the femoral neck under the aid of a three-dimensional scanning apparatus, and the top section of the shield is formed to be an anatomical section identical or similar to the femoral head replacement end, so that the shield of the artificial femoral head can be precisely and stably combined with the femoral head replacement end.
