[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A head fixation device for otolaryngological examination includes a connecting frame 1, on which a limiting component is provided;

[0024] The limiting component includes a connecting sleeve 2 that is slidably connected to the connecting frame 1. A fixing component is provided on the connecting sleeve 2. A cross frame 3 is fixedly connected to the connecting sleeve 2. A slide rod 4 is slidably connected to the cross frame 3. A neck pillow 5 is fixedly connected to the slide rod 4. A rack 6 is fixedly connected to the slide rod 4. A gear 7 that meshes with the rack 6 is rotatably connected to the cross frame 3. An adjusting knob 9 is rotatably connected to the cross frame. The adjusting knob 9 is fixedly connected to the gear 7. A ratchet 8 is also fixedly connected to the adjusting knob 9. A ratchet tooth 10 that matches the ratchet 8 is rotatably connected to the cross frame 3 via a spring shaft.

[0025] In this design, the connecting frame 1 is fixed to the examination chair. When a patient needs to be examined, the patient first sits in the examination chair, and then the height of the backrest is adjusted to ensure that the neck pillow 5 is aligned with the patient's neck. If the backrest height of the examination chair cannot be adjusted, the patient can adjust it by sitting. After the patient sits down, the medical staff turns the adjustment knob 9, which uses the gear 7 to drive the two racks 6 to move closer to each other, thereby clamping the neck pillow 5 against the patient's neck and supporting the patient's chin. At this time, the patient cannot turn their head on their own, which can achieve the effect of fixing the patient's head. While ensuring the patient's comfort, it will not obstruct the patient's head or interfere with the doctor's examination. Moreover, the equipment cost is low and can be directly installed on the existing examination chair.

[0026] Furthermore, the connecting frame 1 includes a main body 101, a round rod 102 is fixedly connected to the upper end of the main body 101, a clamping plate 103 is fixedly connected to the lower end of the main body 101, a pressure plate 104 is slidably connected to the clamping plate 103, and a threaded hole is provided on the pressure plate 104. A screw 105 is rotatably connected to the clamping plate 103, and the screw 105 is threadedly connected to the threaded hole.

[0027] In this design, the clamping plate 103 is L-shaped and can be used with the pressure plate 104 to clamp the back of the consultation chair. After adjusting the position of the clamping plate 103 using the screw 105, the clamping plate 103 and the pressure plate 104 clamp the back of the chair, thus fixing the head fixing device on the consultation chair.

[0028] Furthermore, a support pad 11 is fixedly connected to the side of the cross frame 3 near the neck pillow 5, and the support pad 11 is covered with a cloth cover.

[0029] The support pad 11 is used to support the back of the patient's neck and head, preventing the patient from tilting their head back. This improves the fixation of the patient's head and also enhances the patient's comfort. It should be noted that the support pad 11 can be made of rigid engineering plastic, while the cloth cover can improve the feel of the support pad 11 and avoid causing discomfort to the patient.

[0030] Furthermore, the neck pillow 5 includes a base frame 501, which is fixedly connected to the slide rod 4. An arc-shaped pad 502 is fixedly connected to the base frame 501, and a plastic shell 503 is fixedly connected to the end of the arc-shaped pad 502 away from the slide rod 4. A protective cover is wrapped around the plastic shell 503.

[0031] In this design, since the neck pillow 5 needs to fix the head, it needs to be made of relatively hard engineering plastic and covered with a skin-friendly protective cover. The plastic shell 503 is used to hold the patient's jawbone in place to ensure that the head cannot be turned.

[0032] Furthermore, the fixing component includes a threaded sleeve 12 fixedly connected to the connecting sleeve 2, a rotating sleeve 14 threadedly connected to the threaded sleeve 12, a drive ring 13 fixedly connected to the lower end of the rotating sleeve 14, a locking block 15 fixedly connected to the upper surface of the connecting sleeve 2, a locking groove 16 matching the locking block 15 on the round rod 102, the locking groove 16 being arranged in a circumferential manner, a strip groove on the threaded sleeve 12, and the locking block 15 being disposed within the strip groove;

[0033] In this design, for patients who need to have their face and ears examined, after the neck pillow 5 is placed on the patient's head, the patient can first turn their head to a suitable angle, and then rotate the rotating sleeve 14. When the rotating sleeve 14 moves towards the connecting sleeve 2, it drives the drive ring 13 to move downward. After the drive ring 13 abuts against the locking block 15, it drives the locking block 15 to lock into the locking groove 16. At this time, the connecting sleeve 2 cannot rotate relative to the round rod 102, thus fixing the patient's head at this angle. The strip groove is set to make way for the locking block 15.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
