[0040] Embodiment 1:

[0041] like Figures 1 to 4 As shown, this embodiment provides a head fixing device, including: a fixing frame 1, a fixing plate 2, a supporting component 3 and a fixing component 7.

[0042] The front and rear sides of the fixing frame 1 are provided with cavities, and the two fixing plates 2 are fixedly connected to the front and rear sides of the fixing frame 1 .

[0043] The two support assemblies 3 pass through the fixing plate 2 and are rotatably connected thereto. The support assembly 3 comprises a screw rod 31, a rotating disk 32, a support plate 33 and a fixing bolt 34. The screw rod 31 passes through the fixing plate 2 and is rotatably connected thereto. The top of the screw rod 31 is fixedly connected to the rotating disk 32. The side wall of the rotating disk 32 is provided with a plurality of anti-slip grooves for enhancing the friction between it and the fingers of the medical staff. The lower end of the screw rod 31 is provided with two arc-shaped support plates 33. The upper support plate 33 is fixedly connected to the lower end of the screw rod 31. The two support plates 33 on the upper and lower sides are movably connected. The fixing bolts 34 are threadedly connected to the outer ends of the two support plates 33. By holding the rotating disk 32, the screw rod 31 can be rotated to push the upper support plate 33 close to the patient's shoulder. Then, the lower support plate 33 is passed through the patient's armpit and aligned with the upper support plate 33. The fixing bolt 34 is inserted to provide support for the device, so that the patient's shoulder bears most of the weight and reduces the pressure on the cervical spine.

[0044] The two fixing components 7 are respectively arranged in the two cavities. The fixing components 7 include positive and negative screw rods 71, motors 72, sliders 73, connecting rods 74 and push plates 75. The positive and negative screw rods 71 ​​are rotatably connected to the side walls of the cavity, the motors 72 are fixedly connected to the outer wall of the fixing frame 1, and the output end of the motor 72 passes through the side walls of the fixing frame 1 and is fixedly connected to the positive and negative screw rods 71. The output end of the motor 72 can rotate in two directions. The two sliders 73 are sleeved on the positive and negative screw rods 71. The sliders 73 are provided with threads for matching the positive and negative screw rods 71 ​​and are slidably connected to the positive and negative screw rods 71. One end of the two connecting rods 74 is rotatably connected to the sliders 73, and the push plate 75 is rotatably connected to the end of the connecting rod 74 away from the sliders 73. By starting the motor 72, the positive and negative screw rods 71 ​​can be driven to rotate, so that the two sliders 73 start to slide, driving the connecting rods 74 to move synchronously, so that the push plate 75 is close to the patient's head for preliminary fixation, and cooperates with the support component 3 to prevent the patient's head from shaking.

[0045] Embodiment 2:

[0046] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0047] A bracket 4 is fixedly connected to the upper outer side of the fixing frame 1, four damping rods 5 are fixedly connected to the upper inner side of the bracket 4, an elastic plate 6 is fixedly connected to the lower end of the damping rod 5, and a rubber pad is fixedly connected to the inner part of the elastic plate 6. When the fixing frame 1 is put on the patient's head, the top of the patient's head will generate a thrust on the elastic plate 6, which cooperates with the bracket 4 and the damping rod 5 to further fix the patient's head and improve the stability of the device.

[0048] Embodiment 3:

[0049] The solution in Example 2 is further introduced below in combination with a specific working method, as described below:

[0050] A plurality of telescopic rods 8 are fixedly connected to the opposite side of the two push plates 75, and a spring is sleeved on the telescopic rod 8. The end of the telescopic rod 8 away from the push plate 75 is rotatably connected to a pressure plate 9. The two ends of the spring are respectively fixedly connected to the telescopic rod 8 and the pressure plate 9. The end of the pressure plate 9 away from the telescopic rod 8 is fixedly connected to a protective pad. When the pressure plate 9 is pushed close to the patient's head by the push plate 75, it will fully fit with the patient's head under the action of the telescopic rod 8 and the spring, thereby improving the fixing effect while avoiding injury to the patient's head, thereby providing a certain degree of protection for the patient.

[0051] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0052] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
