The four casters 5 are evenly spaced around the bottom of the base 4. It also includes a servo motor 8, a gear set 9, a pressure sensor 10, a cushion 1001, a distance sensor 11 and a control panel 12. A servo motor 8 is installed in the seat cushion 3 by means of bolt connection. A gear set 9 is provided between the servo motor 8 and the rotating shaft 6. The gear set 9 consists of two full gears. The servo motor 8 and the rotating shaft 6 are both keyed with full gears, and the two full gears are engaged with each other. A pressure sensor 10 for detecting back pressure and a distance sensor 11 for detecting back distance are installed on one side of the backrest 7 by means of bolt connection. The outer side of the pressure sensor 10 is wrapped with a soft cushion 1001. A control panel 12 is installed on the side of the backrest 7 away from the distance sensor 11. The control panel 12 is connected to the pressure sensor 10, the distance sensor 11 and the servo motor 8 signals.

[0026] When it is necessary to use this device for dental operations, first start the control panel 12. After the medical staff sits on the cushion 3, the distance sensor 11 monitors the distance between the medical staff's back and the backrest 7. When the medical staff's back is too far away from the backrest 7, the distance sensor transmits the distance information to the control panel 12. The control panel 12 controls the servo motor 8 to start and rotate. The servo motor 8 drives the rotating shaft 6 and the backrest 7 to rotate through the gear set 9, so that the backrest 7 is close to the back of the medical staff, thereby realizing automatic adjustment of the backrest 7 according to the surgical position of the medical staff, so as to provide support for the medical staff's back during the operation. When the chair needs to be moved as a whole, the caster 5 drives the support seat 1 and the cushion 3 to move through the base 4 by stepping on the ground with the feet.
