Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an auxiliary inspection device for pediatric hip joints. Background Art

[0002] The pediatric hip examination is an examination for developmental dysplasia of the hip. It uses the ultrasonic principle to image the hip joint, observes and analyzes the ultrasonic image structure of the hip joint, and uses the α and β angles to quantify the morphology of the acetabulum to evaluate the development of the hip joint.

[0003] When hospitals currently perform ultrasonic hip joint tests on infants, medical staff are required to use their hands to control the infant's body for testing. They need to control the angle between the infant's trunk and thigh (and the hip joint). Since infants are hyperactive and difficult to control, their bodies move, causing imaging displacement, resulting in errors in the test results, which will affect the doctor's correct judgment of the situation. Therefore, in the prior art, there is an auxiliary device for ultrasonic hip joint examination, such as the Chinese patent announcement number CN205758596U, which discloses an ultrasonic hip joint examination operating table for infants, including an angle holding device, a mattress for infants to lie on their sides, and a trunk fixing bar for the infant's back to be close to, located on the upper surface of the mattress; the angle holding device includes a hip joint pillow, which is close to the inward surface of the trunk fixing bar, and the hip joint pillow is provided with a holding slope for fitting the infant's legs and buttocks to keep the hip joint and the trunk at an obtuse angle.

[0004] In the above-mentioned prior art, although the body of the examined infant can be fixed and the bending angle of the infant's body can be maintained, the two trunk fixing bars are fixedly arranged and cannot be used by infants of different body shapes, and the angle between the trunk and the thigh cannot be adjusted, so the practicality needs to be improved.
