[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a special chair for spinal surgery nursing, comprising a frame 1, a crank 2 rotatably connected inside the frame 1, a lead screw 3 fixedly connected to the outer wall of the crank 2, the outer wall of the lead screw 3 rotatably connected to the inner wall of the frame 1, a sliding block 4 threadedly connected to the outer wall of the lead screw 3, a slide rail 5 slidably connected to the inner wall of the sliding block 4, the lower surface of the slide rail 5 fixedly connected to the inner wall of the frame 1, a transmission plate 6 rotatably connected to the outer wall of the sliding block 4, a fixing block 7 rotatably connected to the outer wall of the transmission plate 6, a seat plate 8 fixedly connected to the upper surface of the fixing block 7, the lower surface of the seat plate 8 being disposed on the upper surface of the frame 1, and a support assembly provided on the inner wall of the frame 1, the support assembly being used to support the seat plate 8 for stable lifting and lowering; the support assembly includes a sleeve 9, the bottom end of the sleeve 9 being fixedly connected to the inner wall of the frame 1, a sliding column 10 slidably connected to the inner wall of the sleeve 9, and the top end of the sliding column 10 being fixedly connected to the lower surface of the seat plate 8;

[0024] Specifically, frame 1 supports crank handle 2 and lead screw 3, ensuring stability during rotation. When crank handle 2 is turned, it drives lead screw 3 to rotate, which in turn causes sliding blocks 4 on both sides to slide along slide rail 5. Slide rail 5 provides greater stability for sliding blocks 4, and frame 1 also supports slide rail 5. Simultaneously, the sliding of sliding blocks 4 causes transmission plates 6 on both sides to rotate, which in turn causes fixed blocks 7 to move up and down. The movement of the fixed block 7 will cause the seat plate 8 to move up and down, thereby adjusting the height of the seat plate 8. This allows the patient to choose a height that is more suitable for their height and physical condition, thus avoiding excessive bending of the waist and knees and reducing pressure on the spine. At the same time, the frame 1 can provide fixed support for the sleeve 9. When the seat plate 8 moves up and down, it will also cause the sliding column 10 to slide on the inner wall of the sleeve 9. The sleeve 9 and the sliding column 10 can ensure that the seat plate 8 maintains stable and smooth movement when rising and falling, avoiding swaying or instability.

[0025] Reference Figure 1The upper surface of the seat plate 8 is fixedly connected with a handrail 11; the lower surface of the frame 1 is fixedly connected with a chair leg 12;

[0026] Specifically, the seat plate 8 can support the handrail 11, the handrail 11 can provide a support point for the hands of the patient, especially when the patient needs to sit down or stand up, which can reduce the burden on the spine and lower limbs, and the chair leg 12 can support the frame 1.

[0027] Referring to Figure 3 The outer wall of the seat plate 8 is fixedly connected with a fixed frame 13, the outer wall of the fixed frame 13 is fixedly connected with a motor 14, and the output end of the motor 14 is fixedly provided with a second lead screw 15; the outer wall of the second lead screw 15 is rotatably connected to the inner wall of the fixed frame 13, the outer wall of the second lead screw 15 is threadedly connected with a moving block 16, the inner wall of the moving block 16 is slidably connected with a guide rail 17, and the lower surface of the guide rail 17 is fixedly connected to the inner wall of the fixed frame 13; the outer wall of the moving block 16 is fixedly connected with a push rod 18, the outer wall of the push rod 18 is slidably connected with a rotating frame 19, the inside of the rotating frame 19 is fixedly connected with a rotating column 20; the outer wall of the rotating column 20 is rotatably connected with a U-shaped plate 21, the outer wall of the U-shaped plate 21 is fixedly connected to the outer wall of the seat plate 8, and the outer wall of the rotating column 20 is fixedly connected with a chair back 22;

[0028] Specifically, the seat plate 8 can support the fixed frame 13, and the fixed frame 13 can support the motor 14; when the motor 14 is turned on, the motor 14 drives the second lead screw 15 to rotate on the inner wall of the fixed frame 13, the rotation of the second lead screw 15 drives the moving block 16 to slide on the guide rail 17, the guide rail 17 ensures the stability of the moving block 16 during sliding, the sliding of the moving block 16 also drives the push rod 18 to slide on the inner wall of the rotating frame 19, the sliding of the push rod 18 on the inner wall of the rotating frame 19 drives the rotating frame 19 to rotate, the rotation of the rotating frame 19 drives the rotating column 20 to rotate, the U-shaped plate 21 ensures the stability of the rotating column 20 during rotation, the seat plate 8 supports the U-shaped plate 21, and the rotation of the rotating column 20 drives the chair back 22 to rotate, so as to adjust the angle of the chair back 22, so that the patient can choose different postures such as half-lying, sitting straight or leaning according to the comfort needs, and the comfort of the patient is improved.

[0029] Working principle: when the nursing chair needs to be used, first of all, the staff can rotate the handle 2 according to the height and body condition of the patient, so that the handle 2 drives the lead screw 3 to rotate, and the rotation of the lead screw 3 drives the sliding block 4 to slide at the sliding rail 5, and the sliding of the sliding block 4 also drives the transmission plate 6 to rotate, and the rotation of the transmission plate 6 also drives the fixed block 7 to move up and down, and the movement of the fixed block 7 also drives the seat plate 8 to move, and the movement of the seat plate 8 also drives the sliding column 10 to slide in the inner wall of the sleeve 9, ensuring the stability of the seat plate 8 when lifting, and finally lifting the seat plate 8 to the height suitable for the patient, when the angle of the chair back 22 needs to be adjusted, first of all, the staff starts the motor 14, so that the motor 14 drives the lead screw 15 to rotate, and the rotation of the lead screw 15 drives the moving block 16 to slide at the guide rail 17, and the sliding of the moving block 16 also drives the push rod 18 to slide in the inner wall of the rotating frame 19, and the sliding of the push rod 18 also drives the rotating frame 19 to rotate, and the rotation of the rotating frame 19 also drives the rotating column 20 inside the U-shaped plate 21 to rotate, and the rotation of the rotating column 20 also drives the chair back 22 to rotate, achieving the effect of adjusting the chair back 22, that is, the nursing chair not only can adjust the height of the seat plate 8, so that the patient can adjust according to his own height and condition, avoid the patient because the height of the chair is not suitable, resulting in the need to bend down or sit down and stand up, reduce the burden of the patient's spine, but also can adjust the angle of the chair back 22, so that the patient can adjust the chair back 22 according to his own preference and body condition when sitting on the nursing chair for a long time, find the most comfortable angle, improve the comfort of the patient, avoid the discomfort caused by the patient's long time fixed posture.

[0030] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included in the protection scope of the present application.
