<p>A C-arm X-ray fluoroscopic machine and a dedicated camera mechanism. The C-arm X-ray fluoroscopic machine includes a C-arm and an X-ray emission device installed on the C-arm. The X-ray emission device is provided with a bulb tube (1) in a housing (6), wherein the bottom of the housing (6) is made as a lead door (4) with an adjustable opening, and also provided with a camera mechanism. The camera mechanism includes a camera device (3) and a reflector (2). The reflector (2) is located on an X-ray optical path in a declination way. The tilted reflector (2) is opposite to the camera device (3) and a subject to be cured. The camera head of the camera device (3) and the X-ray focus point of the bulb tube (1) are symmetric with each other by taking the reflector (2) as a symmetric central axis, so that the focus points of X-ray imaging and camera mechanism imaging are totally consistent, improving the match degree of the image.</p> |
