<p>PURPOSE: A bipolar cup for an artificial hip joint is provided to minimize the interference of a dislocation prevention ring and a ball head by forming the inner diameter of the dislocation prevention ring to be higher than the outer diameter of the ball. CONSTITUTION: A bipolar cup for an artificial hip joint is comprised of a cup body(10), a insert(50), and a dislocation prevention ring. The cup body includes a combining unit(110) prevent an insert from contacting with a contact side to fix insert. A combining accommodation unit includes a taper locking receiving part(111) having a certain angle. The combination unit is combined with the outside of the cup body to be corresponding to the combining accommodation unit. The combination unit includes the taper locking receiving part having a certain angle. The sliding and separation of the insert prevents abrasion through the combination fixing of the cup body and the insert.</p> |
