Description

X-ray examination fixer

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to an X-ray examination fixer.

Background

X-ray imaging is a very common imaging examination in clinical practice. Because of the difference of the density and the thickness of the tissue structure of the human body, when X-rays penetrate through the human body, the absorbed degree is different, and the X-rays with attenuation difference generate images with different black-white contrasts on an imaging medium, so that the X-rays are used for detecting, diagnosing and treating and evaluating various diseases. The X-ray scanning instrument scans the bedding surface with certain thickness of a certain part of a human body, the detector receives the X-ray penetrating through the bedding surface, the X-ray is converted into visible light and then converted into an electric signal through photoelectric conversion, and the electric signal is output and imaged through a computer and is used for inspecting the internal pathological change part of the patient.

When an X-ray examination is performed, the imaging position and the imaging angle have a relatively large influence on the imaging. The trunk parts such as the chest, the abdomen and the like can meet the requirements as long as the trunk parts are kept lying or standing, but the head, the neck and the joints of the four limbs need to keep special shooting positions such as anatomical positions and functional positions according to clinical needs. Due to the radiation of the X-ray, the technician needs to go out of the examination room and take a photographic examination after putting the correct examination position, and the process often requires the patient to keep a posture for several minutes. Because the mobility of the head, the neck and the joints of the four limbs is large, and patients often have the problems of pain or weakness, some patients are difficult to keep the correct body position, the examination is difficult, the examination result is problematic, and the smooth examination is not facilitated.
