[0032] The present utility model provides a neck support for the supine position with the neck extended during thyroid surgery. As Figure 1 shown, in a preferred embodiment, the neck support includes a bracket 10 and an arc-shaped neck pillow 20 provided at the top of the bracket 10 and having a neck groove 20a. The arc-shaped neck pillow 20 includes a bottom support portion 21 and two bottom side support portions 22 respectively provided on the left and right sides of the bottom support portion 21. The bottom support portion 21 and the two bottom side support portions 22 are both arc-shaped. The bottom support portion 21 is fixedly connected to the bracket 10, and the bottom side support portion 22 is movably connected to the bracket 10. A neck groove driving mechanism 30 for driving the bottom side support portion 22 to move relative to the bottom support portion 21 to change the width of the neck groove 20a (referring to Figure 1 the width in the left-right direction as shown) is also installed on the bracket 10. For example, the lower end of the bottom side support portion 22 is rotatably connected to the upper end of the bottom support portion 21, and the neck groove driving mechanism 30 drives the bottom side support portion 22 to rotate relative to the bottom support portion 21 to change the width of the neck groove 20a.

[0033] When using this neck support, first place the patient's neck on the neck groove 20a of the arc-shaped neck pillow 20, and support the back of the patient's neck with the bottom support part 21, so that the patient is in a neck hyperextension supine position. Then, through the neck groove driving mechanism 30, the bottom side support part 22 rotates inwards relative to the bottom support part 21 to change the width of the neck groove 20a, so as to adjust the support surface, protect the two sides of the back of the patient's neck, and thus make the neck subject to a certain binding force during the thyroid surgery to ensure the fixed position of the neck and facilitate the stable progress of the surgical operation. It should be noted that the arc-shaped neck pillow 20 only protects the back and the two sides of the back of the patient's neck, and the front and the two sides of the front of the patient are completely exposed to fully expose the surgical field and facilitate the medical staff to perform the surgery.

[0034] In another preferred embodiment, a soft pad 24 is provided on the surface of the neck groove 20a of the arc-shaped neck pillow 20, and the soft pad 24 is one of a silica gel pad, a latex pad, a gel pad, an airbag pad or a memory foam pad. Specifically, the soft pad 24 can be a whole pad, with a crease at the connection between the bottom support part 21 and the bottom side support part 22, and it bends as the bottom side support part 22 rotates; or the soft pad 24 is composed of three independent sub-soft pads, and the three sub-soft pads are respectively fixedly connected to the surfaces of the bottom support part 21 and the two bottom side support parts 22.

[0035] In the present utility model, the neck groove driving mechanism 30 includes a first screw rod 31 connected to the bracket 10 and a slider 32 located inside the bracket 10 and connected to the first screw rod 31. The first screw rod 31 horizontally passes through the side wall of the bracket 10 and is connected to the slider 32. Preferably, the outer end of the first screw rod 31 is fixedly connected with a first handle 33 located outside the bracket 10. A chute 23 extending in the height direction is provided on the outer wall of the bottom side support part 22, and the slider 32 is clamped with the chute 23 and can slide in the chute 23. For example, the slider 32 has a ball head 321 that is clamped in the chute 23 and can slide in the chute 23.

[0036] Initially, the left and right widths of the neck groove 20a are larger, so that the patient's neck can smoothly enter the neck groove 20a. The medical staff rotates the first handle 33 to rotate the first screw rod 31. The rotation of the first screw rod 31 increases or decreases the distance between the slider 32 and the inner wall of the bracket 10. At the same time, the slider 32 slides in the chute 23 to adapt to the increase and decrease of the aforementioned distance. Specifically, by rotating the first screw rod 31 to increase the distance between the slider 32 and the inner wall of the bracket 10, the bottom side support part 22 can be rotated inwards relative to the bottom support part 21 to reduce the left and right widths of the neck groove 20a and ensure the fixed position of the neck; by rotating the first screw rod 31 in the reverse direction to reduce the distance between the slider 32 and the inner wall of the bracket 10, the bottom side support part 22 can be rotated outwards relative to the bottom support part 21 to increase the left and right widths of the neck groove 20a and ensure that the patient's neck can smoothly enter and exit the neck groove 20a.

[0037] In one embodiment, the first screw rod 31 is in threaded connection with the bracket 10, and the first screw rod 31 is in rotational connection with the slider 32. When the first screw rod 31 is rotated, the length of the first screw rod 31 located inside the bracket 10 increases / decreases, so that the distance between the slider 32 and the inner wall of the bracket 10 increases / decreases, thereby reducing / increasing the left - right width of the neck groove 20a.

[0038] In another embodiment, the first screw rod 31 is in rotational connection with the bracket 10, and the first screw rod 31 is in threaded connection with the slider 32. When the first screw rod 31 is rotated, the length of the first screw rod 31 located inside the bracket 10 remains unchanged, but the length of the engagement between the first screw rod 31 and the slider 32 decreases / increases, so that the distance between the slider 32 and the inner wall of the bracket 10 increases / decreases, thereby reducing / increasing the left - right width of the neck groove 20a.

[0039] In another preferred embodiment, the neck support further includes a housing 40. The housing 40 is a box body with an open upper end. The bracket 10 is installed in the housing 40. The first handle 33 is located above the housing 40. A height - adjusting mechanism 50 for driving the bracket 10 to move up and down is connected to the housing 40. The arc - shaped neck pillow 20 moves up and down with the bracket 10 to adjust its height, so as to adjust the height of the patient's neck according to the surgical needs, making it more convenient for medical staff to perform the operation.

[0040] Specifically, the height - adjusting mechanism 50 includes a second screw rod 51 extending vertically and rotatably connected to the housing 40, and a screw sleeve 52 fixedly connected to the bracket 10 and in threaded connection with the second screw rod 51. A support seat 57 with a bearing is provided in the housing 40 to support the rotational movement of the second screw rod 51; the outer wall of the bracket 10 is vertically slidably connected to the inner wall of the housing 40. For example, the inner wall of the housing 40 has a vertical groove, and the outer wall of the bracket 10 has a sliding column that is inserted into the vertical groove and can slide up and down therein.

[0041] When it is necessary to adjust the height position of the patient's neck, the medical staff rotates the second screw rod 51. Since the bracket 10 is vertically slidably connected to the housing 40, the bracket 10 will not rotate with the second screw rod 51. Under the action of the screw sleeve 52, the rotation of the second screw rod 51 causes the bracket 10 to move up and down in the housing 40, and the arc - shaped neck pillow 20 moves up and down with the bracket 10 to adjust the height position of the patient's neck.

[0042] Preferably, the screw sleeve 52 is fixedly connected to the bracket 10. The screw sleeve 52 penetrates through the bottom of the bracket 10 and its upper end is embedded in the bottom support part 21, thereby increasing the length of the screw sleeve 52 and increasing the engagement length between the second screw rod 51 and the screw sleeve 52, making the connection between the second screw rod 51 and the screw sleeve 52 more firm. Further preferably, the top wall of the vertical groove on the inner wall of the housing 40 also limits the rising position of the bracket 10, thereby not only preventing the bracket 10 from detaching from the housing 40, but also preventing the second screw rod 51 from detaching from the screw sleeve 52.

[0043] In another preferred embodiment, the height adjustment mechanism 50 further includes a rotating rod 53 that is rotatably connected to the outer shell 40 and extends horizontally. There is a support seat 57 with a built-in bearing in the outer shell 40 to support the rotational movement of the rotating rod 53; the rotating rod 53 passes through the right side wall of the outer shell 40 and extends into the outer shell 40. A second handle 56 located outside the outer shell 40 is fixedly connected to the right end of the rotating rod 53. A driving bevel gear 54 is coaxially and fixedly connected to the left end of the rotating rod 53. The driving bevel gear 54 meshes with a driven bevel gear 55 that is coaxially and fixedly connected to the lower end of the second screw rod 51. Among them, the rotating rod 53 is supported by the outer shell 40 and the support seat 57, the driving bevel gear 54 is supported by the rotating rod 53, the second screw rod 51 is supported by the support seat 57, and the driven bevel gear 55 is supported by the second screw rod 51.

[0044] When it is necessary to adjust the height position of the patient's neck, the medical staff rotates the second handle 56 to make the rotating rod 53 rotate. The rotating rod 53 makes the driving bevel gear 54 rotate. The driving bevel gear 54 makes the driven bevel gear 55 drive the second screw rod 51 to rotate. The rotation of the second screw rod 51 makes the bracket 10 drive the arc-shaped neck pillow 20 to move up and down.
