Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 6 As shown, the utility model embodiment provides a fixing bracket for otolaryngology head and neck surgery examination, embodiment 1:

[0028] A fixed bracket for otolaryngology and head and neck surgery examination, comprising a cushion block 1, a headrest portion 2, a first roller 3, a second roller 4 and a rotation drive assembly 5; the upper end of the cushion block 1 is rotatably connected to a rotating member 6, the first roller 3 and the second roller 4 are oppositely arranged on both sides of a rotating shaft 61 of the rotating member 6, and the axes of the first roller 3 and the second roller 4 are parallel; the headrest portion 2 is made of a flexible material and its front and rear ends are respectively fixedly connected to the front and rear ends of the cushion block 1, a accommodating chamber 21 is formed between the headrest portion 2 and the cushion block 1, the first roller 3 and the second roller 4 are located in the accommodating chamber 21 and support the headrest portion 2 at two different positions respectively; the rotation drive assembly 5 is located on the cushion block 1 and is used to adjust the rotation angle of the rotating member 6.

[0029] In this embodiment, the first roller 3 and the second roller 4 respectively support the headrest portion 2, so that the headrest portion 2 can have various shapes:

[0030] In the first form, the rotary drive assembly 5 drives the rotating member 6 to rotate so that the first roller 3 and the second roller 4 are in a horizontal state, so that the headrest portion 2 is also in a horizontal state. At this time, the shape of the headrest portion 2 is consistent with the shape of an ordinary headrest, and can be used for normal ear, nose and throat shell examination of patients;

[0031] In the second form, the rotary drive assembly 5 drives the rotating member 6 to rotate so that the first roller 3 and the second roller 4 tilt toward the front end of the headrest 2, so that the level of the first roller 3 is lower than that of the second roller 4, so that the headrest 2 presents an inclined surface tilted forward, and then the patient's shoulder and neck rest on the first roller 3, and the back of the head rests on the second roller 4, so that the patient's head can tilt forward;

[0032] In the third form, the rotary drive assembly 5 drives the rotating member 6 to rotate so that the first roller 3 and the second roller 4 tilt toward the rear end of the headrest 2, so that the horizontal height of the first roller 3 is higher than the horizontal height of the second roller 4, so that the headrest 2 presents an inclined surface tilted backward, and then the patient's neck rests on the first roller 3, the back of the head tilts backward and is located between the second roller 4 and the first roller 3, and is supported by the headrest 2. In this case, the patient's nasal cavity or mouth faces obliquely upward, which makes it easier for doctors to perform surgical examinations on the patient's nose and throat;

[0033] To summarize, medical staff can adjust the shape of the headrest 2 in advance by rotating the drive assembly 5 according to the patient's examination part, so that the headrest 2 can provide certain support to the patient's head or shoulder and neck, thereby stabilizing the patient's head. At the same time, the patient's head rests on the headrest 2 of various shapes, which can also make the patient's head present different angles, which is convenient for medical staff to examine. In addition, during the examination of the patient by the medical staff, the angle of the rotating part 6 can also be fine-tuned by the drive assembly 5, so that the surface tilt angle of the headrest 2 is appropriately changed, thereby fine-tuning the angle of the patient's head, which is convenient for medical staff to examine, and at the same time can always provide stable support to the patient's head.

[0034] Specifically, the first roller 3 and the second roller 4 are both configured as a shaft 31 and a sponge layer 32 sleeved on the outside of the shaft 31, and the sponge layer 32 can improve the comfort of the patient;

[0035] The rotating member 6 is provided with two connecting rods 62, and the two connecting rods 62 are symmetrically arranged at both ends of the rotating shaft 61, and the two connecting rods 62 are vertically distributed to the rotating shaft 61. The first roller 3 and the second roller 4 are both connected between the two connecting rods 62, and the first roller 3 and the second roller 4 are located at both ends of any one of the connecting rods 62. Two mounting blocks 11 are provided at the upper end of the cushion block 1, and the rotating shaft 61 is rotatably connected to the circular holes 111 of the two mounting blocks 11, so as to realize the rotational connection between the rotating member 6 and the cushion block 1.

[0036] The diameter of the first roller 3 is greater than that of the second roller 4, so that in the headrest portion 2 in the above three forms, it is always the first roller 3 that provides strong support to the patient's neck. The larger the diameter of the first roller 3, the higher the content of the corresponding sponge layer 32, which further improves the patient's comfort.

[0037] Embodiment 2:

[0038] like Figure 3 and Figure 4 As shown, the rotation drive assembly 5 includes a first gear 51, a second gear 52, a rotating rod 53 and a locking assembly 7, and the pad 1 is configured as a shell; the first gear 51 is coaxially mounted on the rotating shaft 61, the inner end of the rotating rod 53 is rotatably connected to the inside of the pad 1, the outer end of the rotating rod 53 passes through the pad 1 to the outside of the pad 1, the second gear 52 is coaxially mounted on the rotating rod 53, and the first gear 51 and the second gear 52 are meshed and connected; the locking assembly 7 is mounted on the outside of the pad 1 to lock the rotating rod 53.

[0039] Specifically, the locking assembly 7 includes a first annular block 71 and a second annular block 72. The first annular block 71 is installed on the outer side of the cushion block 1 and is coaxial with the rotating rod 53. The inner side wall of the first annular block 71 is annularly distributed with a plurality of clamping grooves 711; the second annular block 72 is slidably arranged on the rotating rod 53. The inner wall of the second annular block 72 is provided with a limiting block 721 and is slidably matched with the limiting groove 531 on the outer wall of the rotating rod 53 in the axial direction of the rotating rod 53. The outer end of the second annular block 72 is installed with a knob 54. The outer wall of the second annular block 72 is annularly distributed with a plurality of clamping blocks 722.

[0040] In this embodiment, the knob 54 is pushed so that the plurality of blocks 722 slide into the plurality of slots 711 respectively, so as to realize the locking of the rotating rod 53, thereby preventing the rotating rod 53 from rotating on its own, and the shape of the headrest portion 2 is also locked; if the shape of the headrest portion 2 needs to be adjusted, the medical staff needs to pull the knob 54 so that the plurality of blocks 722 are pulled out from the plurality of slots 711 respectively. Since the second annular block 72 and the rotating rod 53 are axially limited by the limit block 721, the medical staff can drive the rotating rod 53 to rotate together by turning the knob 54, and the second gear 52 rotates with the rotating rod 53, and cooperates with the first gear 51 to rotate the rotating member 6. Under the change of the position of the first roller 3 and the second roller 4, the headrest portion 2 is supported at different positions, thereby achieving the purpose of adjusting the shape or inclination of the headrest portion 2.

[0041] Specifically, a stopper 55 for limiting the position of the knob 54 is installed at the outer end of the rotating rod 53 . The stopper 55 can prevent the knob 54 from falling off the rotating rod 53 and is used to limit the position of the knob 54 .

[0042] Embodiment three:

[0043] like Figure 1 and Figure 2 As shown, the left and right sides of the outer surface of the headrest portion 2 are recessed inward to form a concave surface 22, so that the patient's head or neck can be rested on the concave surface 22, so that the patient's head is given a certain degree of flexibility by the protruding parts on both sides of the headrest portion 2, thereby improving the stability of the patient's head.

[0044] Specifically, covering cloth 23 is sewn on the left and right ends of the headrest portion 2, and the covering cloth 23 is used to cover the mechanical structure in the accommodating chamber 21 to improve the aesthetics of the fixing bracket. The covering cloth 23 can be made of crepe (made of elastic fiber and has a certain elasticity). The size of the covering cloth 23 is larger than the contour of the side of the headrest portion 2, so that when the shape of the headrest portion 2 changes, the covering cloth 23 can have room for movement.

[0045] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
