Description
Technical Field
The utility model relates to a director technical field especially relates to an acetabular bone location director.
Background
The artificial hip joint replacement relates to two aspects of acetabulum and femur, wherein the difficulty lies in the treatment of the acetabulum side, because the acetabulum cup needs to be arranged according to a certain angle (abduction 40 degrees minus 5 degrees, anteversion 15 degrees minus 5 degrees), the risk of avoiding postoperative artificial joint dislocation is higher, the operation failure is directly caused, the pain is brought to patients, the economic burden is increased, and the waste of medical resources is caused. However, at present, no artificial hip replacement instrument is made in China or imported, no tool for precisely positioning the acetabular cup exists, the angle of the acetabular cup during operation depends on the subjective feeling and experience of an operator to a great extent, and great uncertainty exists, so that an acetabular positioning guider is proposed to solve the problems.
Disclosure of Invention
The utility model aims at solving the problems that the artificial hip joint replacement instrument exists in the prior art, the instrument of the acetabular cup is not precisely positioned, the angle of the acetabular cup is placed in the operation to a great extent depending on the subjective feeling and experience of an operator, and the defect of great uncertainty exists, and the acetabulum positioning guider is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the acetabulum positioning guider comprises a T cone, wherein a cylindrical sleeve is movably sleeved on the outer side of the T cone, one end of a connecting rod is fixedly mounted on the outer side of the cylindrical sleeve, one side of a connecting block is fixedly mounted on the other end of the connecting rod, a plug is fixedly mounted on the other side of the connecting block, a conical sleeve is movably sleeved at the bottom end of the T cone, a pair wire handle is fixedly mounted on the outer side of the conical sleeve, a jack is formed in the pair wire handle, and the plug is inserted into the jack.
Preferably, the included angle between the pair of wire handles and the T cone is 40 degrees.
Preferably, the included angle between the cylindrical sleeve and the connecting rod is 90 degrees.
Compared with the prior art, the beneficial effects of the utility model reside in that:
(1) when the scheme is used, a plug fixedly installed on the connecting block is inserted into the jack, finally, the T cone sequentially penetrates through the cylindrical sleeve and the conical sleeve, then the acetabular cup is placed in the channel, the aligning handle is knocked, and the acetabular cup is placed in the acetabular cup, so that the anteversion angle and the abduction angle of the acetabulum are accurately positioned;
(2) the utility model discloses anteversion angle, the abduction angle of location acetabular bone that can be accurate satisfy people's user demand, simple structure, convenient to use.
