[0017] Compared with the related art, the beneficial effects of the present application are as follows:
[0018] The ankle X-ray photography auxiliary device provided by the present application plays a great role when X-ray photography of the ankle of a patient is needed.
[0019] First, when the foot and ankle double foot anteroposterior weight-bearing X-ray photography is needed, the staff will first put the flat panel detector into the first placement slot under the detection table. At this time, the position of the flat panel detector is parallel to the upper support surface of the detection table, thereby ensuring the accuracy and clarity of photography. Then, guide the patient to walk onto the upper support surface of the detection table, and ask him to keep his two feet apart at a certain distance and parallel, so as to ensure that the X-ray image can completely and clearly capture the patient's double feet. Next, the ball tube for emitting X-rays is set above the dorsum of the foot, usually close to the patient's torso. At this time, the center of projection needs to be accurately aligned with the midpoint of the first metatarsal-cuneiform joint of the patient's double feet, so as to ensure the accuracy and pertinence of photography. After all preparations are completed, X-ray photography can be performed, thereby obtaining the foot and ankle double foot anteroposterior weight-bearing X-ray image.
[0020] In addition, when the foot and ankle double foot posterior force line position X-ray photography is needed, the operation process is slightly different. At this time, the staff will first put the flat panel detector into the second placement slot under the detection table, and the flat panel detector presents a certain angle of inclination relative to the vertical plane. Then, guide the patient to walk onto the upper support surface of the detection table again, and ask him to stand facing the flat panel detector, with his two feet also apart at a certain distance and parallel. Next, the ball tube for emitting X-rays is set behind the patient, and by adjusting, it is ensured that the X-rays emitted by the ball tube are perpendicular to the detection surface of the flat panel detector. At this time, the center of projection needs to be aligned with the midpoint of the patient's double ankle joints, and a large piece of photography is performed, which needs to include the lower 1 / 3 part of the tibia, while paying attention to avoid the internal and external rotation of the patient's feet, so as to ensure the accuracy and integrity of photography. After all preparations are completed, X-ray photography can be performed, thereby obtaining the foot and ankle double foot posterior force line position X-ray image.
[0021] As can be seen from the above operation process, the foot and ankle X-ray photography auxiliary device provided by the present application can achieve the purpose of X-ray photography of the patient's ankle from multiple angles and directions when the patient stands on the detection table, by skillfully placing the flat panel detector in different placement slots and correspondingly setting the ball tube capable of emitting X-rays. This design not only greatly improves the accuracy and clarity of photography, but also is simple and convenient to operate, effectively improving the efficiency and quality of patient treatment.
