[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a head positioning pad, including a base, the base including a base plate 1 and a movable plate 2 slidably mounted on the base plate 1, and a locking member 3 for locking the moving position of the movable plate 2 is installed on the movable plate 2. Through the cooperation of the movable plate 2 and the locking member 3, the moving position of the movable plate 2 can be locked, thereby improving the stability of the arc support plate 10 in use.

[0031] A semi-circular forehead support plate 4 is provided above the base plate 1. The lower surface of the forehead support plate 4 is connected to the upper surface of the base plate 1 through a first telescopic rod 5 with a self-locking function. The height of the first telescopic rod 5 can be adjusted vertically to meet the height requirements of different surgeries and patients. The self-locking function locks the length of the telescopic rod 5 after extension. The two ends of the forehead support plate 4 are fixed with a first fixing strap 6 for fixing to the head. The first fixing strap 6 can connect the patient's head to the forehead support plate 4, improving the stability of the head and the forehead support plate 4. The opposite sides of the base plate 1 are fixed with a second fixing strap 7 for fixing to the operating table. The second fixing strap 7 is made of woven strap. Because the base itself is heavy, any movement of the base after the patient's head is fixed on it may cause neck injury. Therefore, the base needs to be firmly fixed to the operating table. The woven strap passes through the bottom of the operating table and is fixed with Velcro.

[0032] The movable plate 2 is equipped with two self-locking sliding mechanisms 8. Each sliding mechanism 8 is equipped with a second telescopic rod 9 with a self-locking function. The second telescopic rod 9 is equipped with an arc-shaped support plate 10 for supporting the mandible. The installation position of the protruding surface of the arc-shaped support plate 10 is adjustable. The structure of the second telescopic rod 9 is the same as that of the first telescopic rod 5. It can also adjust the height of the arc-shaped support plate 10. The bottom of the second telescopic rod 9 can slide on the movable plate 2 and can be fixed at any point to ensure support stability. The protruding surface of the arc-shaped support plate 10 can slide within it and be fixed at any point on its arc, so that the arc-shaped support plate 10 can provide sufficient support force when supporting the left and right positions of the patient's mandible.

[0033] The forehead support plate 4 includes a 180° semi-circular steel frame. The steel frame is wrapped with a silicone layer or a sponge layer, so that the steel frame is completely located within the silicone layer or the sponge layer. This makes the surface of the forehead support plate 4 soft, increases friction, prevents the patient's head from moving, and ensures that the patient will not be injured.

[0034] The first fixing strap 6 is a braided strap, one of which is fixed with hook and loop fasteners and the other is fixed with loop fasteners. By using the adhesion between the hook and loop fasteners, the patient's forehead is fixed in the semicircle of the forehead support plate 4, thereby improving the stability of the head and the forehead support plate 4.

[0035] The base plate 1 has a sliding groove 11 for the sliding plate 2 to slide. The opposite sides of the sliding plate 2 are integrally formed with protruding edges 12. The side wall of the sliding groove 11 has a sliding groove 13 for the protruding edges 12 to slide, so that the sliding plate 2 can move in the sliding groove 11 to adjust the distance between the forehead support plate 4 and the arc support plate 10 to adapt to different ages and face lengths.

[0036] The locking component 3 includes a locking bolt. An elongated hole 14 for the locking bolt to move is provided on the movable plate 2 located above the slide groove 13. A threaded through hole 15 for the locking bolt to be screwed into is provided on the protruding edge 12. When locked, the threaded end of the locking bolt passes through the threaded through hole 15 and abuts against the bottom wall of the slide groove 13. By loosening or tightening the locking bolt, the fastening force between the movable plate 2 and the base plate 1 can be adjusted. When the locking bolt is loosened, the locking bolt does not apply force to the base plate 1. At this time, the movable plate 2 can move in the movable groove 11. When the locking bolt is tightened, the locking bolt applies a fastening force to the base plate 1, which increases the fastening force between the movable plate 2 and the base plate 1, locks the position of the movable plate 2 after it has moved, and improves the stability of the movable plate 2 in use.

[0037] The sliding mechanism 8 includes a slider 81 with a hand screw 82 threaded onto it. One end of the hand screw 82 passes through the slider 81 and abuts against the inner bottom of the sliding track 83. The movable plate 2 has a sliding track 83 for the slider 81 to slide on, and the two sliding tracks 83 are located on the same horizontal line. The second telescopic rod 9 is installed on the slider 81. By utilizing the sliding cooperation between the slider 81 and the sliding track 83, the distance between the two second telescopic rods 9 can be adjusted, thereby adjusting the distance between the two arc-shaped support plates 10 to meet the needs of different body positions. At the same time, the hand screw 82 is threaded onto the slider 81. By tightening the hand screw 82, the moved slider 81 can be locked inside the sliding track 83, and the slider 81 can no longer move. When the hand screw 82 is loosened, the slider 81 can move within the sliding track 83.

[0038] A connecting block 16 is fixed to the upper end of the second telescopic rod 9, and a T-shaped block 17 is fixed to the connecting block 16. The protruding surface of the arc-shaped support plate 10 is provided with an arc-shaped groove 19 for the T-shaped block 17 to slide, so as to adjust the support position of the arc-shaped support plate 10 and make the arc-shaped support plate 10 have sufficient support force when supporting the left and right positions of the patient's mandible. A hand-tightening bolt 18 is inclinedly screwed to the connecting block 16. The threaded end of the hand-tightening bolt 18 extends into the arc-shaped groove 19. The working principle of the hand-tightening bolt 18 is the same as that of the hand-tightening screw 82 and the locking bolt. By loosening or tightening the hand-tightening bolt 18, the position of the arc-shaped support plate 10 after adjustment can be locked or unlocked, which facilitates the movement of the arc-shaped support plate 10 during adjustment and the fixation of its position during use.

[0039] The concave surface of the arc-shaped support plate 10 is fixed with a leather layer, and the leather layer is filled with sponge. The sponge increases the softness of the arc-shaped support plate 10 and increases friction to prevent the patient's head from moving. The two symmetrical arc-shaped support plates 10 are spliced ​​together to be the same size as the forehead support plate 4. The angle and direction of the support force of the arc-shaped support plate 10 in the left-right and vertical directions can be adjusted at will through the sliding mechanism 8, the second telescopic rod 9, the connecting block 16 and the T-shaped block 17.

[0040] To enhance patient protection, the head positioning pad also includes an deployable head cover that movably rests on the base; as... Figure 5 and Figure 6 As shown, the headgear and base work together to protect and support the head, improving patient comfort. The headgear is also expandable, making it convenient for preoperative intubation and other procedures.

[0041] The headgear includes a main body 20. Two forehead plates 21 are integrally formed on the upper sides of the main body 20. One end of each forehead plate 21 is fixed with a Velcro strap 22 for connecting the two forehead plates 21 together. This allows for adjustment and secure fixation at the forehead and jawline, ensuring the patient's head remains protected throughout the process. Two face plates 23 are integrally formed on the lower sides of the main body 20. A third fixing strap 24 for securing the jawline is fixed to the lower end of each face plate 23. A clearance hole for ear protection is provided at the connection point between the main body 20 and the face plate 23. An annular ear protection ring 25 is fixed within the clearance hole. The ear protection ring 25 is thickened, similar to a boxing headgear, to prevent pressure on the outer ear even when the patient is lying on their side.

[0042] The forehead plate 21 is made of a soft plastic, such as polyimide, that can be completely flattened or rolled up 360°. The main body 20 and the forehead plate 21 are combined into a T-shaped plastic plate. The horizontal part supports the forehead, and the vertical part supports the back of the head, providing complete protection for the head. The plastic plate also has some elasticity and support. It is covered with sponge to ensure comfort and provide support from the back of the head to the neck. The plastic plate is covered with an outer fabric cover that is integrated with the other parts. The plastic plate is shaped with stitching to facilitate its installation and removal while ensuring that the entire headgear can be easily attached and detached. Figure 6 As shown, the headgear can be unfolded to ensure that it will not interfere with anesthesia and endotracheal intubation procedures before the patient is positioned.

[0043] The headgear also includes a Velcro patch 26 for bonding with the first fixing strap 6. The Velcro patch 26 is located at the upper end of the headgear and extends from the outer wall of one side of the forehead plate 21 through the main body 20 to the outside of the other side of the forehead plate 21. The Velcro patch 26 is suitable for situations where the head needs to be securely fixed. The Velcro patch 26 can be used to better fix the head by bonding with the first fixing straps 6 at both ends of the forehead support plate 4 on the base. When connected with the first fixing strap 6, if the surface of the Velcro patch 26 is hook-on, at least one of the first fixing straps 6 must be a braided strap with double-sided hook-on Velcro (one side is used to bond with another braided strap, and the other side is bonded to the Velcro patch 26 on the headgear), and the other first fixing strap 6 is a braided strap with hook-on Velcro, so that it can bond with the Velcro patch 26 on the headgear without affecting the bonding of the two braided straps.

[0044] In general anesthesia scenarios, after unfolding the headgear, it is placed under the patient's head and neck. At this time, general anesthesia and endotracheal intubation can be performed. Then, the unfolded headgear is used to completely wrap and fix the patient's head using the Velcro strap 22 on the forehead and the third fixation strap on the chin. Regardless of the patient's position, the head can be adjusted in three dimensions through the sliding mechanism 8 of the base, the second telescopic rod 9, and the T-shaped block 17 (at this time, the vertical height of the first telescopic rod 5 also needs to be adjusted accordingly), adapting to the fixation and adjustment of the head in any surgical position except for the head and neck.

[0045] It should be noted that both the first telescopic rod 5 and the second telescopic rod 9 are self-locking achieved by using a mechanical locking mechanism (such as a spring clip, friction plate, or thread) combined with a high-friction coefficient material, utilizing the relationship between friction and normal force. These telescopic rods are available for purchase on the market.

[0046] The principle of locking position for hand-tightened screws 82, locking bolts, and hand-tightened bolts 18 is the same: all use bolts as brakes. When tightened, the head of the bolt presses against a certain surface, generating friction and thus fixing the position; when loosened, the friction decreases, and the part can move.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
