Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, and in particular to a portable auxiliary positioning device. Background Art

[0002] Knee osteoarthritis refers to a chronic bone and joint disease caused by knee cartilage degeneration and bone hyperplasia. Patients often have symptoms such as redness, swelling and pain in the knee, pain when going up and down stairs, knee soreness and discomfort when walking, and knee stiffness. It is common in middle-aged and elderly people. Degenerative lesions of the knee joint, heavy physical labor, and excessive fatigue are the main causes of knee osteoarthritis.

[0003] Weight-bearing X-rays of the knee often require the patient to stand and take anteroposterior and lateral X-rays of the knee. In addition, X-rays of the intercondylar notch of the knee are performed to observe the bone wear of the posterior femoral condyle, the intercondylar notch notch, and the tibial intercondylar eminence.

[0004] To perform X-ray photography of the intercondylar fossa of the patient's knee joint, the patient is often required to lie prone on a photographic diagnostic bed, with the affected limb flexed at the knee and the calf supported by an auxiliary positioning device so that the calf and the film are at an angle of about 60°; the film is placed in front of the knee, and the center of the film corresponds to the lower edge of the patella. The existing auxiliary positioning device includes a cushion and a support block. When in use, the cushion is laid under the knee, and a support block with a predetermined height is used to support the middle and lower part of the calf so that the calf and the film are at an angle of about 60°. However, the auxiliary positioning device composed of a cushion and a support block is not easy to carry or store, and the position of the support block may be adjusted multiple times depending on the experience of the medical staff, which is cumbersome to operate and wastes film. Therefore, it is a problem that technicians in this field need to solve to provide a portable auxiliary positioning device that is easy to carry and store. Utility Model Content
