Description
Technical Field
The utility model belongs to the technical field of medical treatment auxiliary instrument technique and specifically relates to an auxiliary device for hip joint imaging examination is related to.
Background
Hip imaging examination is one of the most practical examination methods for hip disease examination. Normal persons lie supine on the examination table in a standard anatomical position, requiring an anteversion angle of the femoral neck of between about 10 ° and 15 °. In order to better display the image of the whole femoral neck, during the hip joint examination, the two lower limbs are required to be straightened and the feet are required to be rotated inwards by 15-20 degrees, the toes of the examined person are required to be closed, and the femoral neck is kept parallel to the whole detector, so that the more complete hip joint image is obtained.
Each imaging examination of the hip requires pronation of the foot, including: hip radiography, hip DXA scanning, hip CT and QCT scanning, hip MR scanning. Compared with X-ray photography, the rest examinations require that the pronation time of both feet of the examined person is longer, especially the time of hip joint MR scanning is more than tens of minutes.
In the actual imaging examination, most of the examined people come from trauma, postoperative reexamination, middle-aged and elderly people, people with weakened muscle function, and the like. Most of the examinees are difficult to independently keep the internal rotation of the feet, the posture of the examinees is kept still in the examination process, the internal rotation angle of the feet is limited, the feet are not independently separated in the examination process, and the like, so that the examination quality of the hip joint images cannot meet the clinical diagnosis requirement. For example: the images contain small trochanter images during DXA examination, so that the error of the bone density result is large; shortening of femoral neck images in MR coronal examination; in some cases, there are a lot of motion artifacts in the examination images, which affect the whole clinical diagnosis and judgment, and even cause misdiagnosis.
The current operation steps of hip imaging examination are as follows: the image technician closes the feet of the examined person, so that the examined person can keep the feet internally screwed and achieve the natural opening of the femoral neck until the whole examination is completed. This is difficult for trauma, post-operative review, middle aged and elderly people, and those with impaired muscle function, who cannot pronate themselves due to pain and remain on examination. The family members of the examined person are usually asked to accompany the examination in the machine room, and the ankles of the examined person are pressed by both hands to be rotated inwards and kept until the examination is completed, but the following defects exist:
1. the internal rotation angles of the feet of the examined person can not be accurately controlled, and sometimes, even with the help of accompanying examined family members, the internal rotation angles can not be accurately controlled;
2. the hands of the family members are not stable, and the limbs are likely to shake in the pressing process, so that a larger motion artifact is caused;
3. besides the MR examination, the accompanying family members may be damaged by random effects of radiation ionization in the machine room.
