Technical Field
The utility model relates to the technical field of medical auxiliary equipment, concretely relates to lumbar vertebrae oblique position X ray photography auxiliary positioning device.
Background
The oblique lumbar X-ray photography is a special X-ray photography. The conventional lumbar X-ray photography only shoots a positive lateral position film, and has the defect that the situation of the lumbar isthmus cannot be displayed. Oblique photography can make up for the defect, can well display lumbar isthmus fissure, and has great help for orthopedics doctors to make clear diagnosis.
However, oblique photography has been a technical difficulty, and the difficulty is angle control. Textbooks have a specification for angles: when the oblique photography is carried out, the angle between the human coronal plane and the X-ray detector is 45 degrees. Two main problems are faced at any moment in practical work, firstly, differences of individual anatomy, including sex differences, weight differences, age differences and the like, namely the physiological curvature of lumbar vertebra of each person is different, and if the physiological curvature is mechanically required by textbooks, lumbar vertebra oblique X-ray films meeting the diagnosis requirements of clinicians cannot be shot. Second, operator variability, including radiologic technician scholarship variability, technical level variability, cognitive level variability, etc., can result in a result that multiple radiographs may be required to obtain a satisfactory image, which can increase the radiation dose to the patient.
The conventional mode of the existing lumbar vertebra oblique position X-ray photography is implemented by adopting a patient lying position, the patient lies on the back on a movable photography table, the body is straight, the opposite side is raised, the lower limb is bent to enable the detected side to be close to the table top, the coronal surface of the body is 45 degrees with the table top, the support is positioned by the aid of the waist back cushion or the self-carried support on the photography table, and then the photography table is moved to a proper position for X-ray photography. In the mode, the posture of the patient is inconvenient to adjust when the patient is in a sitting position, the stability of the inclined posture of the patient is not suitable to be controlled, the image is easy to be blurred, particularly, the positioning mark 'spinous process' is under the positioning mark, the central line of the irradiation field and the spinous process cannot be accurately positioned due to the trunk shielding, and the image is easy to shift or incomplete to display. In this case, it is a better way to shoot the lumbar vertebrae in a standing position for X-ray photography, but there is currently no corresponding auxiliary positioning device.
