[0044] like Figure 3 As shown, the rotating unit also includes a moving rack 3 of a strip structure; an annular rack 4 is arranged on the outer circumference of the arc plate 2; a moving groove 5 for the moving rack 3 to move is provided on the fixing device body 1, and an annular groove 6 for accommodating the annular rack 4 is provided on the inner wall of the arc groove; the annular groove 6 is connected with the moving groove 5, and the opening of the moving groove 5 is located on the side parallel to the axis of the arc plate 2 on the fixing device body 1, and the opening of the annular groove 6 is located on the two walls at the opening of the arc groove; the moving rack 3 extends into the moving groove 5 from the opening of the moving groove 5; the annular rack 4 is accommodated in the annular groove 6, and the moving rack 3 is meshed with the annular rack 4. In this embodiment, the end of the moving groove 5 away from its opening is in a closed state to prevent external dust from entering the moving groove 5. At the same time, a handle is provided at the end of the moving rack 3 away from the opening of the moving groove 5. As the operator pulls the moving rack 3 through the handle, the arc plate 2 rotates along the arc groove.

[0045] A fixing assembly is provided at the opening of the moving groove 5; the fixing assembly includes a fixed end and a movable end; the fixed end of the fixing assembly is mounted on the side of the fixing device body 1; the movable end of the fixing assembly is detachably fixedly connected to the moving rack 3. In this embodiment, the fixing assembly includes a fixing plate 7 and a fixing rod 8. The fixing plate 7 is a rectangular plate-like structure, which is placed in the horizontal direction and parallel to the moving rack 3.

The elastic band 12 includes two, which are tightened at the forehead and chin of the patient respectively.

[0049] In this embodiment, cable ties 13 are provided on two opposite sides of the fixing device body, the fixing device body is connected to the operating table through the cable ties 13, and cable ties 13 are provided at the four end corners of the fixing device body to prevent relative displacement between the fixing device body and the operating table.

[0050] In order to prevent dust from falling into the annular groove 6 and the limiting groove, dust covers 14 are provided on both walls of the arc groove opening, and the dust covers 14 cover the openings of the annular groove 6 and the limiting groove.

[0051] The specific implementation method is as follows: before the infusion port operation, the patient's head is placed on the flexible cushion 11 inside the arc plate 2 through the elastic band 12 .

[0052] After determining the surgical position, the surgeon or nurse first removes the fixed rod 8, and then pulls the moving rack 3. During the process of pulling the moving rack 3, the surgeon or nurse communicates with the patient whether the rotation angle is uncomfortable. When the surgical requirements are met, the moving rack 3 is no longer pulled. At this time, the fixed rod 8 limits the moving rack 3, and the deflection angle of the patient's head does not change. Then the surgeon starts the operation.
