Diagnosis mainly includes fluoroscopy, radiographs, CT, MRI, ultrasound, digital subtraction, angiography, etc. Medical film, also known as medical imaging film, is a special film used to record and store medical images. Medical film is relatively widely used in the medical industry. It has a certain waterproof effect and will not fade. The surface is quite hard. Doctors observe the film during surgery mainly to obtain detailed imaging data of patients, so as to better understand the structure of the surgical site and possible lesions, so as to formulate appropriate surgical plans. Since it is inconvenient to take and put the film during the operation, medical staff need to clamp the film and install it on the viewing light box.

When the first disc 6 moves toward the main frame 1 When one end of the first link 10 rotates, under the action of the first connecting rod 10, the second disc 7 will also rotate toward the main frame 1. At the same time, since the second disc 7 and the third disc 8 are connected by a rotating shaft, the third disc 8 can push the fourth disc 9 through the second connecting rod 11, so that the cylindrical rod inside the arc groove 4 slides into the straight groove 5. At this time, the two cylindrical rods are both located in the straight groove 5, the supporting leg 12 is in a vertical state with the main frame 1, and the pressing plate 14 is in a parallel state with the main frame 1.

At the same time, since the second disk 7 and the third disk 8 are connected by a rotating shaft, the third disk 8 can push the fourth disk 9 through the second connecting rod 11, so that the cylindrical rod inside the arc groove 4 slides into the straight groove 5. At this time, the two cylindrical rods are both located in the straight groove 5, the supporting leg 12 is in a vertical state with the main frame 1, and the pressing plate 14 is in a parallel state with the main frame 1. Continue to rotate the first disk 6, and the two cylindrical rods will move to the depth of the straight groove 5 at the same time.
