One end of the support spring 409 is fixedly connected to the inner wall of the arc-shaped cylinder 407.

[0031] Furthermore, during use, by adjusting the coordination of the screw 402, sliding plate 403, and movable rod 404 in component 4, when the screw 402 is rotated, since the screw 402 and sliding plate 403 are threadedly connected, the sliding plate 403 will move along the axial direction of the screw 402, thereby driving the movable rod 404, which is rotatably connected to it, to move. The movable rod 404 is rotatably connected to the lower surface of the chest support plate 3, ultimately achieving an angle change of the chest support plate 3 relative to the leg support plate 2. This allows the chest support plate 3 to be conveniently adjusted to a suitable angle according to actual needs when different patients undergo CT examinations, improving the patient's comfort during the examination and ensuring that the body is in a suitable examination posture. At the same time, the arc-shaped top rod 408 slides inside the arc-shaped cylinder 407. One end of the support spring 409 is fixed to the inner wall of the arc-shaped cylinder 407, and the other end can provide elastic support force for the arc-shaped top rod 408. When the chest support plate 3 changes position vertically due to external forces or other factors, the support spring 409 can play a buffering role.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 and Figure 3This is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

The lower end of the head support pillow 501 is fixedly connected to the surface of the chest support plate 3. Both sides of the head support pillow 501 are fixedly connected with support plates 502. The upper end of the support plate 502 is rotatably connected with a fixing frame 503. One end of the fixing frame 503 is fixedly connected with a head pad 512. The end of the fixing frame 503 away from the head pad 512 is threadedly connected with a fixing screw A506. One end of the fixing screw A506 is fixedly connected with a chin support block 507.

[0034] Specifically, a top frame 504 is fixedly connected to the surface of the fixed frame 503, a fixed screw B509 is threadedly connected to the surface of the top frame 504, a fixed arc plate 510 is fixedly connected to one end of the fixed screw B509, a knob A508 and a knob B511 are fixedly connected to one end of the fixed screw A506 and one end of the fixed screw B509 respectively, an adjusting bolt 505 is provided at the connection between the support plate 502 and the fixed frame 503, guardrails 6 are fixedly connected to both sides of the leg support plate 2 and the chest support plate 3, and anti-slip pads 7 are fixedly connected to the surface of the leg support plate 2 and the chest support plate 3.

[0035] Furthermore, the headrest pillow 501 provides basic support for the patient's head. The support plates 502 on both sides are rotatably connected to the fixed frame 503. The angle of the fixed frame 503 can be adjusted by the adjusting bolt 505, so that the head pad 512 and the chin support block 507 can better conform to the contour of the patient's head. The chin support block 507 connected by the fixing screw A can effectively fix the patient's chin and prevent the head from moving during the examination. At the same time, the fixing arc plate 510 connected by the fixing screw B can provide secondary fixation for the top of the patient's head, thereby achieving all-round fixation of the head and avoiding shaking of the patient's head during the CT examination, thus ensuring the accuracy of the CT scan images. The protective railings 6 fixedly connected to both sides of the leg support plate 2 and chest support plate 3 can effectively prevent the patient from rolling off the support frame due to body movement during the examination, improving the safety of the examination process. At the same time, the anti-slip pads 7 on the surface of the leg support plate 2 and chest support plate 3 can increase the friction between the patient's body and the support frame, preventing the patient's body from sliding on the support frame, further enhancing the stability of the patient during the examination and ensuring that the examination can be carried out smoothly.

[0036] Working principle: In use, the patient first lies on the surface of the chest support plate 3 and leg support plate 2, then the patient's head is placed on the surface of the headrest pillow 501. The headrest pillow 501 provides basic support for the patient's head. The support plates 502 on both sides are rotatably connected to the fixing frame 503. The angle of the fixing frame 503 can be adjusted by the adjusting bolt 505, so that the head pad 512 and the chin support block 507 can better conform to the contour of the patient's head. The chin support block 507 connected by the fixing screw A can effectively fix the patient's chin and prevent the head from moving during the examination. At the same time, the fixing arc plate 510 connected by the fixing screw B can provide secondary fixation to the top of the patient's head, thus achieving all-round fixation of the head and avoiding shaking of the patient's head during the CT examination, thereby ensuring the accuracy of the CT scan image. After the patient's fixed position is fixed, the screw 402, The sliding plate 403 and the movable rod 404 work together. When the screw 402 is rotated, the sliding plate 403 moves along the axial direction of the screw 402 because the screw 402 and the sliding plate 403 are threadedly connected. This drives the movable rod 404, which is rotatably connected to it, to move. The movable rod 404 is rotatably connected to the lower surface of the chest support plate 3, ultimately changing the angle of the chest support plate 3 relative to the leg support plate 2. This allows the chest support plate 3 to be easily adjusted to a suitable angle according to the actual needs of different patients during CT examinations, improving the patient's comfort during the examination and ensuring that the body is in a suitable examination posture. At the same time, the arc-shaped top rod 408 slides inside the arc-shaped cylinder 407. One end of the support spring 409 is fixed to the inner wall of the arc-shaped cylinder 407, and the other end can provide elastic support for the arc-shaped top rod 408. When the chest support plate 3 changes position due to external forces or other factors, the support spring 409 can play a buffering role.
