Abstract

The invention discloses a design thought and an application method of a hip joint rotation center locator. The rotation center locator comprises a connecting pile body movably fixed to the edge of acetabulum, wherein the upper end face of an acetabulum body is the edge of the acetabulum, namely the acetabulum edge, fixing feet are connected to the outer surface of the acetabulum edge, and a connecting supporting rod is fixed to the upper end face of each fixing foot; the inner side of the acetabulum edge is an acetabulum center location area, and the position of a hip joint rotation center isdetermined through the arrangement of a center location hole according to an indication guide pin track. The hip joint rotation center locator is composed of the fixing feet, the connecting supportingrods and the connecting pile body; the acetabulum body, the acetabulum edge and the location area are normal anatomical positions; the influence of body position change of a patient on an intraoperative filing angle can be avoided through combination of the locator and the acetabulum; the hip joint rotation center is located in a physical structure mode; and the problems of large differences of located rotation centers among different operators and inaccurate positioning points due to different body types of the different patients are solved.

Description

technical field [0001] The invention relates to the technical field of CIP cleaning systems, in particular to a hip joint rotation center locator. Background technique [0002] Total hip arthroplasty has become the most effective treatment for advanced hip joint diseases, and clinicians have gradually gained a deeper understanding of the importance of reconstructing the center of rotation of the hip joint. Accurate reconstruction of the center of rotation can not only optimize the biomechanical environment around the hip joint, To improve the mobility of the hip joint, it is very important to restore the normal center of rotation during total hip replacement. However, the center of rotation is not a definite anatomical structure and can only be measured indirectly. [0003] At present, there are many methods for indirectly measuring the center of rotation, but there are few methods for clearly locating the center of rotation during surgery. Most of them are inferred based on...
