[0002] Medical film is a key material for recording and displaying images in medical imaging diagnosis. With the development of medical imaging technology, medical film is not only used in traditional X-ray photography but also widely applied in the field of digital imaging. Medical film plays an important role in medical imaging diagnosis. Although digital imaging technology is developing day by day, film still has its unique application value in image recording, storage, and display. With the progress of technology, medical film has been continuously improved in aspects such as improving imaging quality, reducing radiation dose, and enhancing operation convenience to meet clinical needs.

[0003] Searching for prior art, the publication number CN211388952U discloses a cutting device for medical dry film. It includes a bottom shell, and a top shell is fixedly connected to the top of the bottom shell. An opening is penetrated and dug on one side side wall of the top shell, and a first guiding groove is penetrated and dug on the top of the top shell. One end side of the first guiding groove arranged inside the top shell is provided with a contact plate, and the contact plate is partially in contact with the first guiding groove. The bottom of the contact plate is fixedly connected with a fixing plate, and one end of the fixing plate away from the contact plate is fixedly connected with the inner wall of the top shell. A connecting rod is inserted into the side wall of the top shell away from the fixing plate, and the connecting rod is slidably connected with the top shell. One end of the connecting rod arranged outside the top shell is fixedly connected with a connecting plate, and a pulling handle is fixedly connected to one side of the connecting plate away from the connecting rod. One end of the connecting rod arranged inside the top shell is fixedly connected with a clamping plate, and a spring group is fixedly connected between the clamping plate and the inner wall of the top shell. A cutting blade is arranged below the clamping plate, and one end of the cutting blade is fixedly connected with the output end of an electric telescopic rod through a mounting plate. The end of the electric telescopic rod away from the cutting blade is fixedly connected to the inner wall of the top shell 2 through a mounting seat. A second guiding groove is penetrated and dug on the top of the bottom shell directly below the first guiding groove, and two crushing rollers are rotatably connected inside the bottom shell below the second guiding groove. One ends of the two crushing rollers are respectively fixedly connected to the output ends of two crushing motors, and both crushing motors are fixedly connected to the outer side wall of the bottom shell. A plurality of crushing teeth are fixedly connected to the crushing rollers, and a blanking inclined plate is fixedly connected to the inner bottom of the bottom shell. A blanking port is penetrated and dug on the side wall of the bottom shell on one side of the blanking inclined plate.

[0004] In the comparative document, through the device with the first guiding groove and the second guiding groove, when in use, by pulling the pull handle to drive the connecting rod, the fixed soft pad is separated from the fixed plate, and then the film is inserted into the inner part of the top shell through the first guiding groove. After adjusting the position of the film, the pull handle is released, and the connecting rod returns to its original position under the action of the spring group, so as to fix the film on the fixed plate through the fixed soft pad. Then, the electric telescopic rod is started to cut the film. After the cutting is completed, the connecting rod is pulled again to take out the film. However, there are various sizes of medical films, such as 14 inches × 17 inches, 10 inches × 12 inches, 8 inches × 10 inches, etc., and films of multiple sizes cannot be cut.
