Description

Technical Field

[0001] The utility model relates to a medical auxiliary device, in particular to an auxiliary device for maintaining the inversion, eversion and anterior drawer stress position of the ankle joint. Background Art

[0002] After the ankle is injured, the stability of the ankle is destroyed, resulting in frequent ankle sprains, which is called ankle instability, and imaging examinations are usually required. Conventional imaging examinations are magnetic resonance imaging, but MRI appointments are time-consuming and some patients have metal implants that prevent them from completing the examination. X-ray stress film is quick and easy, and will not be interfered by metal implants. In clinical practice, ankle inversion stress film, eversion stress film and anterior drawer stress film are often used to quickly and effectively evaluate the degree of ankle ligament injury and ankle stability. It is a relatively intuitive, simple and efficient diagnostic method.

[0003] In clinical diagnosis and treatment, patients cannot maintain their body position independently, and assistants are often required to apply stress to complete the examination. Most people lack the corresponding medical background knowledge and skills training, and it is difficult to assist patients to maintain the standard radiographic position, thus affecting the film effect; at the same time, if the assistant is unable to assist in the radiography due to objective conditions, such as pregnancy, breastfeeding, young age, and imperfect upper limbs, it is even more difficult to complete an accurate X-ray evaluation.

[0004] A Chinese patent with publication number CN205885408U discloses an ankle joint scanning auxiliary pressure device, which fixes the calf and foot through a position control plate and a foot support, and then applies a certain amount of pressure laterally and perpendicularly to the calf through a pressure applicator to adjust the position of the ankle joint, thereby controlling the inversion angle of the ankle joint and the forward displacement of the foot. In this way, the coronal inversion and inversion movement of the ankle joint and the movement in the sagittal plane under stress position can be obtained, and the anterior drawer test and talus tilt test can be realized, providing a clear ankle joint anatomical perspective for X-ray scanning.

[0005] However, the above-mentioned pressurization method is too direct and the stress is relatively concentrated. The amount of soft tissue on the ankle and the front of the tibia is small and the blood supply is poor. When pressurizing, it may cause iatrogenic injury and induce pain and swelling. Therefore, the utility model provides an ankle joint stress position auxiliary device. Utility Model Content
