Hip center of rotation locator

Abstract

The invention discloses a design idea and an application method of a hip joint rotation center locator. The rotation center locator is a connecting pile body fixed on the edge of the acetabulum. The outer surface of the edge is connected with a fixed foot, and the upper end of the fixed foot is fixed with a connecting strut. The inner side of the acetabular edge is the acetabular center positioning area, and the setting of the center positioning hole determines the position of the hip joint rotation center according to the track of the guide needle. The hip joint rotation center locator is composed of a fixed foot, a connecting strut, and a connecting post body. The acetabular body, the acetabular edge, and the positioning area are normal anatomical positions, and the combination of the locator and the acetabulum can avoid the patient's position The impact of the change on the rasp angle during the operation, using the physical structure to locate the center of rotation of the hip joint, solves the problem of the large difference in positioning the center of rotation between different surgeons due to the different body shapes of different patients, and the positioning point is not accurate The problem.

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...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a locator for the center of rotation of the hip joint to solve the various methods for indirect measurement of the center of rotation proposed in the above-mentioned background technology. According to the experience and anatomical structure of the operator, the positioning of the center of rotation varies greatly among different operators. The use of surgical navigation is not only a cumbersome process, but also a problem of high cost.
