Problems solved by technology

[0002] The installation of acetabular prosthesis in traditional hip replacement surgery mostly relies on the experience of the surgeon. Usually, the doctor can determine the abduction angle and anteversion angle of the acetabular cup by observing the relationship between the acetabular cup edge and the horizontal plane and vertical plane. If Patients with severe hip joint deformity or incorrect lying posture on the hospital bed will bring great difficulties to the doctor to install the acetabular prosthesis, which may cause serious consequences such as dislocation of the acetabular prosthesis
[0003] The model reconstruction accuracy of the popular acetabular prosthesis positioning devices on the market is high, the error tolerance rate is low, and it takes a long time and the cost is high

Abstract

The invention discloses an acetabular prosthesis positioning apparatus which comprises a guide needle, a positioning guide barrel and a positioning plate. The guide needle is used for guiding the positioning of an acetabular prosthesis; the positioning guide barrel is provided with an opening end and a closed end, the closed end is provided with a plurality of second through holes and a fourth through hole, a positioning needle is fittingly arranged in each second through hole, and the fourth through hole is used for allowing the guide needle to pass through; the positioning plate is rotatablyarranged on the positioning guide barrel, a limit hole for the positioning plate to be penetratingly arranged is arranged in the side wall of the positioning guide barrel, and the part, extending tothe cavity of the positioning guide barrel, of the positioning plate, is provided with a third through hole and a fifth through hole for respectively allowing the positioning needle and the guide needle to penetrate. The positioning needle of the acetabular prosthesis positioning apparatus can be matched with acetabulum of the acetabular prosthesis, matching angle of the positioning guide barrel and the acetabular prosthesis can be accurately positioned, the guide needle can be fixed in the acetabulum of a patient firmly and accurately, and positioning accuracy of the guide needle can be improved.

Description

technical field [0001] The invention relates to the field of hip joint replacement, in particular to an acetabular prosthesis positioning device. Background technique [0002] The installation of acetabular prosthesis in traditional hip replacement surgery mostly relies on the experience of the surgeon. Usually, the doctor can determine the abduction angle and anteversion angle of the acetabular cup by observing the relationship between the acetabular cup edge and the horizontal plane and vertical plane. If Patients with severe hip joint deformity or incorrect lying posture on the hospital bed will bring great difficulties to the doctor to install the acetabular prosthesis, which may cause serious consequences such as dislocation of the acetabular prosthesis. [0003] Currently popular acetabular prosthesis positioning devices on the market require high model reconstruction accuracy, low error tolerance, and are time-consuming and costly. [0004] The above information disc...
