Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a protective device for X-ray shooting of knee joints. Background Art

[0002] The knee joint is the largest and most complex joint in the human body. Knee joint diseases are very common in clinical practice. Diseases such as inflammation, tumors, trauma, nutritional and metabolic disorders are likely to affect this part. When the knee joint is diseased, it is generally necessary to take AP and lateral films for diagnosis and treatment. Different patient positions are required for different films. In clinical practice, AP films can almost 100% achieve correct positioning and are easier to operate. Knee joint X-rays are a commonly used medical imaging method to evaluate and diagnose knee joint structure and related problems.

[0003] When photographing the lateral position of the knee joint, the angle between the thigh and the calf needs to be maintained at about 135 degrees. However, it is difficult for the patient to flex the knee joint to a specific angle during the photographing, and it is also difficult to maintain this angle. Based on these problems, Chinese patent CN218960760U discloses a knee joint lateral position photographing aid. Through the coordinated use of adjusting bolts, conical limit tables, rotating rings, connecting components, etc., when the angle between the first support plate and the second support plate is rotated to about 135 degrees, it can be fixed and limited, so that the patient's thigh and calf can always be maintained at an angle of about 135 during the photographing process. This not only improves the shooting efficiency, but also facilitates the capture of clearer pictures, thereby facilitating doctors to accurately diagnose and treat patients, and is highly practical.

[0004] After the auxiliary device is fixed on the patient's leg, the tightness of the straps varies due to the different sizes of the thigh circumference and the calf circumference. If it is too tight, it will cause marks on the patient's legs, and if it is too loose, the auxiliary device will fall off the patient's legs. At the same time, the straps fixed on the patient's legs will also affect the X-ray shooting effect. Utility Model Content
