[0002] Spinal surgery is a procedure that treats various spinal conditions, and the surgical sites include the cervical, thoracic, and lumbar spines. During posterior spinal surgery, the patient's spine must maintain a certain curvature, which is achieved through the use of a support bracket. Existing spinal surgery brackets have an arc-shaped support plate, on which the patient lies prone. The support plate's curvature is fixed and cannot be adjusted. However, different patients require different curvatures during surgery, requiring adjustments to the curvature, resulting in inconvenience. Utility Model Content

[0006] Preferably, the threaded sleeve is fixedly connected to a second bevel gear, the second bevel gear is meshed with a first bevel gear, the first bevel gear is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the bed plate through a bearing.

[0007] Preferably, a knob is fixedly connected to the rotating shaft.

[0008] Preferably, bolts are threadedly connected to the two connecting blocks, and the bolts abut against the cross bar.

[0009] Preferably, a plurality of mounting grooves are provided on the elastic plate, airbags are provided in each of the plurality of mounting grooves, and the plurality of airbags are connected by a connecting mechanism.

[0010] Preferably, the connecting mechanism includes a connecting pipe, the connecting pipe is connected to the plurality of airbags, and a valve is provided on the connecting pipe.

[0011] Preferably, a pillow is provided on the bed board.

[0012] The utility model proposes a spinal surgery bracket device, which has the beneficial effect of adjusting the position of the threaded rod in the threaded sleeve by rotating the threaded sleeve, thereby changing the curvature of the elastic plate and the supporting curvature during surgery, so that it can be used by different patients.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example: Refer to Figure 1-3 A spinal surgery support device includes a bed board 1, a pillow 2 is provided on the bed board 1, and support legs are fixedly connected around the bed board 1, which are not shown in the figure.

[0020] A threaded sleeve 11 is rotatably connected to the bed board 1 through a bearing, a threaded rod 10 is threadedly connected to the threaded sleeve 11, a fixed plate 16 is fixedly connected to the threaded rod 10, an elastic plate 4 is fixedly connected to the fixed plate 16, both ends of the elastic plate 4 are fixedly connected to connecting blocks 7, and two connecting blocks 7 are penetrated by a cross bar 8, and the two cross bars 8 are fixedly connected to the bed board 1. By rotating the threaded sleeve 11, the position of the threaded rod 10 in the threaded sleeve 11 is adjusted, and the curvature of the elastic plate 4 is changed, thereby changing the support curvature during surgery so that different patients can use it.

[0021] A second bevel gear 14 is fixedly connected to the threaded sleeve 11, and a first bevel gear 13 is meshed on the second bevel gear 14. A rotating shaft 12 is fixedly connected to the first bevel gear 13. The rotating shaft 12 is rotatably connected to the bed board 1 through a bearing. By rotating the rotating shaft 12, the threaded rod 10 is driven to rotate, thereby adjusting the position of the threaded rod 10 in the threaded sleeve 11, thereby adjusting the height of the middle part of the elastic plate 4. Since the two ends of the elastic plate 4 are limited by the cross bar 8, the arc shape of the elastic plate 4 is adjusted.

[0022] The rotating shaft 12 is fixedly connected with a knob 3, and the knob 3 can be grasped to drive the rotating shaft 12 to rotate.

[0023] Example 2: In Example 1, when the arc is adjusted, the connecting block 7 will be driven to slide on the crossbar 8. Since the two ends of the elastic plate 4 are not fixed, the stability will be affected. Figure 1-3 As another preferred embodiment of the present invention, based on embodiment 1, the two connecting blocks 7 are both threaded with bolts 9, and the bolts 9 are in contact with the cross bar 8. By tightening the bolts 9, the two ends of the elastic plate 4 are fixed, thereby ensuring the stability of the elastic plate 4 during use.

[0024] During use: by rotating the rotating shaft 12, under the action of the first bevel gear 13 and the second bevel gear 14, the position of the threaded rod 10 in the threaded sleeve 11 is adjusted, thereby adjusting the height of the middle part of the elastic plate 4, adjusting the position of the connecting block 7 on the cross bar 8, thereby adjusting the arc shape of the elastic plate 4, and then tightening the bolt 9 to fix the position of the connecting block 7, the person lies on the elastic plate 4, and then performs the operation.

[0025] Example 3: In Example 2, when the elastic plate 4 is used for support, the operation time is long and the force position remains unchanged, which affects the blood circulation and causes pressure sores. Figure 1-4 As another preferred embodiment of the present invention, on the basis of Example 2, a plurality of mounting grooves 15 are provided on the elastic plate 4, and air bags 5 are provided in the plurality of mounting grooves 15. The plurality of air bags 5 are connected by a connecting mechanism, and the connecting mechanism includes a connecting pipe 6. The connecting pipe 6 is connected to the plurality of air bags 5. A valve is provided on the connecting pipe 6. By connecting the connecting pipe 6 with an air pump, gas is pumped into the air bag 5, and the air bag 5 will expand. Then the valve is closed, and the air bag 5 will support the patient. After a period of time, the air is deflated, so that the elastic plate 4 supports the patient again, so that the supporting part can be switched to prevent the occurrence of pressure sores.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
