The invention discloses a
caput femoris surface replacement prosthesis. The
caput femoris surface replacement prosthesis comprises a joint part and a
collum femoris insertosome, wherein one end, awayfrom the
collum femoris insertosome, of the joint part is a spherical surface, attachment structural
layers capable of being embedded into a
human body are arranged at one end, close to the
collum femoris insertosome, of the joint part and the collum femoris insertosome, and a fixing unit is also arranged on the collum femoris insertosome. According to the
caput femoris surface replacement prosthesis, a spherical
surface structure at the joint part can replace a caput femoris surface joint of a
human body, the collum femoris insertosome can be inserted into medullary space of collum femoris, the attachment structural
layers are arranged on one side of the joint part and on the surface of the collum femoris insertosome and used for biological fixation,
bone ingrowth is facilitated, and final
embedment of the prosthesis and bone of the
human body is realized; and besides, the fixing unit is arranged on the collum femoris insertosome and can prevent the prosthesis from rotating or retreating, the position
correctness and stability of the prosthesis are effectively guaranteed, and the service life of the prosthesis is prolonged.
