At this time, the movable plate 4 will drive the rotating component to rotate synchronously. When the movable plate 4 is flush with the fixed plate 2, the movable plate 4 and the connecting plate 1 are fixed by the fixed component. At this time, the overall width of the brain pressure board can be increased by the movable plate 4, so that the patient's brain tissue can be pulled through the cooperation between the fixed plate 2 and the movable plate 4. When it is necessary to extract the effusion exuded from the patient's diseased part, you only need to use the liquid suction component to conveniently extract the effusion in the patient's diseased part, thereby preventing the effusion from affecting the doctor's observation effect, saving time and effort.
