[0002] Ordinary operating tables provide doctors with a stable, comfortable and safe working platform, and they play the most important role in the success of patients' operations. Electric operating tables can adjust the height and angle more conveniently and quickly on the basis of ordinary operating tables, while improving the safety and stability of operations.

[0003] In some delicate eye surgeries, such as laser surgery, subtle adjustments to the position of the patient's head and body are often required to accommodate different stages of the operation.

[0004] Most existing operating tables use mechanical adjustment to adjust the position of the operating table. Compared with electric adjustment, mechanical adjustment has lower stability and reliability, and cannot meet some precise position requirements, such as adjustment of a few millimeters, which will affect the effect of the operation. More seriously, it will cause some surgical accidents. Summary of the invention

[0040] The two translation mechanisms are fixedly mounted on the base 5 and the carrier frame 4, respectively, and are used to drive the bed 1 to move along the width direction (X axis) and the length direction (Y axis) of the bed 1;

[0041] The translation mechanism of this embodiment includes a reciprocating unit and a driving unit 11. The moving structure of the reciprocating unit is connected to the carrier 4 or the bed 1. The output end of the driving unit 11 is drivingly connected to the input end of the reciprocating unit. Under the action of the driving unit 11, the carrier 4 or the bed 1 moves following the moving structure.

[0042] Specifically, the reciprocating moving unit (not shown in the figure) of this embodiment adopts a ball screw structure, the compactness of the ball screw structure is high enough to meet the height adjustment required for surgery, and the driving unit 11 adopts a servo motor 17. The installation method and transmission structure of the two are both existing technologies, so they are not described here in detail;

[0043] In addition, the operating bed is also provided with two position feedback mechanisms respectively installed on the carrier 4 and the bed body 1, and the position feedback mechanisms are used to feedback the movement amount of the carrier 4 and the bed body 1 to ensure that the movement amount is correct;

[0044] The position feedback mechanism (not shown in the figure) of this embodiment adopts a grating ruler, the reading head is connected to the carrier frame 4 or the bed 1, and the grating ruler is installed on the base 5 or the carrier frame 4;

[0045] Correspondingly, a control panel is provided in the operating table, and the control panel is electrically connected to the servo motor 17 and the position feedback mechanism, so as to facilitate the control of the start and stop of the servo motor 17 according to the movement amount feedback by the position feedback mechanism, so as to achieve accurate control of the movement amount;

[0046] Embodiment 2

[0047] On the basis of the first embodiment, this embodiment proposes an adjustable operating bed, which also includes a headrest 2, which is connected to the bed body 1 and moves synchronously with the bed body 1. The headrest 2 is separately provided to achieve separate fine adjustment of the headrest 2. The headrest adjustment structure is an existing structure, so it is not described here in detail.

[0048] In addition, in order to improve the patient's comfort, a mattress 12 is installed on the bed body 1;
