Thereafter, the first adjustment handwheel is rotated forward, the first adjustment handwheel drives the first screw rod forward, and the lumbar support pillow at the front end of the first screw rod pushes the human lumbar spine forward, thereby performing positive correction on the human lumbar spine. After the positive correction of the human lumbar spine is completed, the first adjustment handwheel is rotated in the opposite direction, the first adjustment handwheel drives the first screw rod backward, and the lumbar support pillow at the front end of the first screw rod leaves the human lumbar spine. The waist strap and the shoulder strap are loosened, and the person can stand up.

[0011] The scoliosis correction chair provided by the utility model can correct the lumbar vertebra of a human body laterally when the person sits on the chair surface, the second adjusting hand wheel is installed at the rear end of the second screw rod, and the third adjusting hand wheel is installed at the rear end of the third screw rod. The position of the left rib mechanism box on the left armrest is adjusted up and down to reach the appropriate position of the human body, and the left rib mechanism box is fixed. The position of the right rib mechanism box is adjusted up and down to reach the appropriate position of the human body, and the right rib mechanism box is fixed. Then, the person is fixed by the waist strap and the shoulder strap. The upper end of the shoulder strap is movably connected to the chair back and the position of the shoulder strap on the chair back is adjusted up and down to adapt to people of different heights. Thereafter, the second adjusting hand wheel is rotated forward, the second adjusting hand wheel drives the second screw rod forward, and the left rib support pillow at the front end of the second screw rod presses against the left rib of the human body. The third adjusting hand wheel is rotated forward again, the third adjusting hand wheel drives the third screw rod forward, and the right rib support pillow at the front end of the third screw rod presses against the right rib of the human body. Then, the second adjusting hand wheel or the third adjusting hand wheel is rotated according to the direction of correction required, thereby correcting the lumbar vertebra of the human body laterally. After the lateral correction of the human lumbar vertebra is completed, the second adjusting handwheel and the third adjusting handwheel are rotated in reverse. The second adjusting handwheel drives the second screw rod to retreat, and the third adjusting handwheel drives the third screw rod to retreat. The left rib support pillow at the front end of the second screw rod leaves the left rib of the human body, and the right rib support pillow at the front end of the third screw rod leaves the right rib of the human body.

Thereafter, the first adjusting handwheel is rotated forward, and the first adjusting handwheel drives the fourth screw rod to move forward. The cervical vertebra support pillow at the front end of the fourth screw rod is pressed against the back of the cervical vertebra. The fourth adjusting handwheel is then rotated forward, and the fourth adjusting handwheel drives the adjusting shaft to rotate forward. The adjusting shaft drives the cervical vertebra traction bracket to rise through the ratchet and ratchet rod structure or the reducer. The cervical vertebra traction bracket drives the traction cross bar to rise. The traction cross bar drives the traction rope to rise. The traction rope drives the traction sleeve to rise, thereby correcting the cervical vertebra. After the cervical vertebrae are corrected, the fourth adjusting handwheel is rotated in the opposite direction. The fourth adjusting handwheel drives the adjusting shaft to rotate in the opposite direction. The adjusting shaft drives the cervical vertebrae traction bracket to descend through the ratchet rod structure or the reducer. The cervical vertebrae traction bracket drives the traction crossbar to descend. The traction crossbar drives the traction rope to descend. The traction rope drives the traction sleeve to descend. The traction sleeve is separated from the human head, and the human body can stand up. During the cervical vertebrae correction, the spring scale type traction force display shows the traction force. The traction crossbar is movably connected to the cervical vertebrae traction bracket. During the cervical vertebrae correction, the traction crossbar is pulled backward, and the traction rope changes from a vertical position to a posterior and superior position, so that the cervical vertebrae is pulled backward and upward, achieving a cervical vertebrae correction angle in a wider angle range. The first adjusting handwheel is matched with the first screw rod and the fourth screw rod, and can be installed and unloaded as needed. The cervical vertebrae traction bracket and the chair back are connected by round tubes. The cervical vertebrae traction bracket and the chair back can be rotated left and right to achieve a correction angle in a wider angle range.
