The application relates to the technical field of protection devices, and discloses a sputtering-preventing protection device for bone sawing and grinding, which comprises a protection device main body, a tightening belt and a fixing assembly. The protection device is provided with a first transparent plastic film and a second transparent plastic film. In the operation process of sawing a bone or grinding a hip socket, the splashed bone fragments, blood and tissues will first adhere to the surface of the first transparent plastic film. When the surgeon cannot see the internal surgical field through the film, the first transparent plastic film is pulled to drive the bent end of the second transparent plastic film to be unfolded, the adhesive material on the back surface is peeled off, and the first transparent plastic film is separated from the second transparent plastic film. At this time, the first transparent plastic film adhered with the bone fragments, blood or tissues is separated. The method can shield the splashed objects and effectively avoid the obstruction of the vision caused by the adhesion.
