Abstract

The invention provides a caput femoris implant and a hip joint implant. The caput femoris prosthesis comprises outer spherical bodies, and internal taper holes used for accommodating taper heads are formed in the outer spherical bodies; the ends of the internal taper holes penetrate through the spherical surfaces of the outer spherical bodies; at least one air exhausting passage is formed in the outer spherical bodies, and the air exhausting passages are used for exhausting air in the internal taper holes.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a femoral head prosthesis and a hip joint prosthesis. Background technique [0002] Artificial hip replacement is to replace the diseased hip joint of the human body with an artificial hip joint prosthesis to restore the normal physiological activities of the patient. In the current mainstream artificial hip joint prosthesis, ceramic materials have been widely recognized by the market and welcomed by doctors for their excellent biological inertia and wear resistance. [0003] In hip prostheses with ceramic femoral heads, some unwelcome loads exist and are extremely difficult to detect, so all hip prostheses currently on the market have a shadow of this load. This load is that after the femoral stem is assembled with the femoral head, a cavity will be created at the top of the femoral stem. At the beginning of the surgical installation, the cavity is air and wil...
