A device for measuring the angle of an acetabular cup of an artificial hip joint is provided to obtain the precise operation angle of the acetabular cup quickly by measuring the operation inclination angle with first and second angle measuring units. A device(100) for measuring the angle of an acetabular cup of an artificial hip joint is composed of: a body block(110); a direction indicating member fixed at one side of the body block and equipped with plural direction indicating rods; a first angle measuring unit(130) rotatably combined with the body block and provided with a first graduated ruler(133) and a first indicating unit; a second angle measuring unit(140) turned for a shaft(S2) that is not parallel to a rotary shaft(S1) of the first angle measuring unit, and provided with a second graduated ruler(142) and a second indicating unit to measure the rotational angle; a connecting rod(150) connecting an acetabular cup shaft to the rotary shaft of the second angle measuring unit; and a detaching member(160) installed at the end of the connecting rod to install the acetabular cup shaft selectively. |
