X-ray is an ionizing radiation, an important technique commonly used in clinical examinations to determine the relative positional relationship of tissues, tumors, or foreign matters of different densities in a human body. In addition to being used for examination, X-ray instruments, such as C-arm machines, G-arm machines, can also be used for guiding surgery, in particular interventional surgery, orthopedic surgery, urological surgery, etc. When the X-ray instrument is used for guiding an operation, the X-ray instrument is usually started in two modes of a handheld remote control mode and a foot pedal mode, and when the X-ray instrument is used, the X-ray instrument is divided into a shooting mode and a perspective mode, the shooting mode is single shooting, the perspective mode is X-ray continuous irradiation, and the foot pedal starting mode is used more frequently, because an operator can start the X-ray according to own requirements at any time.

It is known that X-rays are harmful to the human body, and that exposure to a certain range may cause gene mutation, with the risk of inducing cancer. When the X-ray is used for guiding an operation, an operator wears lead clothing in advance, but other medical staff, such as a nurse, an anesthesiologist, a passer-by at an operating room entrance, a patient and the like, are not protected. The foot pedal arranged on the ground is easy to be stepped on by an operator or other walking medical staff by mistake, so that unprotected medical staff is forced to receive excessive radiation, and the foot pedal needs to be improved to have the function of preventing the mistaken stepping. One chinese patent publication No. CN202891959U discloses a safety type C-arm foot switch, in order to set an arch-shaped protective cover on the foot rest, the operator needs to extend the toe into the protective cover to trigger the X-ray switch, but such foot rest is bulky, difficult to store, and easy to trip medical staff. Therefore, a device and a system for preventing mistaken stepping on an X-ray are needed, and the problems that the existing device for preventing mistaken stepping on an X-ray instrument is large in size, difficult to store and easy to trip medical staff are solved.
