Through the cooperation between the circular ring 4 and the slider 5, the triangular block 6 rotates inside the circular ring 4. Through the restriction of the slide groove 3, the triangular block 6 can adjust the opening size as needed, so that the contact area between the buttocks and the seat cushion 1 can be adjusted according to the specific affected area of ​​the patient, avoiding long-term close contact with the seat cushion 1 causing pain or even worsening of the affected area. By adjusting the opening on the seat cushion, the direct contact between the affected area and the seat cushion can be moderately reduced, which helps to keep the affected area ventilated and dry, reduce the risk of bacterial growth, and thus accelerate recovery. At the same time, reducing unnecessary pressure also helps to relieve the patient's pain and discomfort, and improve the overall quality of rehabilitation.

[0023] like Figures 1 to 5 As shown, a protection box 10 is fixedly installed on one side of the seat cushion 1, and a threaded rod 11 is rotatably installed inside the protection box 10. A rack 14 is threadedly sleeved on the outer surface of the threaded rod 11, and a sleeve tooth 13 is rotatably installed on one side of the rack 14 and the sleeve tooth 13 is engaged with the rack 14.

[0024] By providing a threaded rod 11, the rotation of the threaded rod 11 causes the rack 14 to slide and drive the sleeve gear 13 to rotate, the rotation of the sleeve gear 13 drives the hinged rod 12 to rotate, and the hinged rod 12 drives the backrest 2 to flip, so that the patient can adjust the angle of the backrest according to needs. By adjusting the backrest angle, the patient can more effectively disperse the body weight and avoid the center of gravity being concentrated on the buttocks for a long time when sitting for a long time, causing unnecessary pressure and pain. This design is particularly important for patients in the anorectal department because it helps to reduce the direct contact time between the diseased part and the seat cushion, reducing the pain or risk of deterioration caused by long-term pressure.
