[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 An expandable medical operating table in this embodiment includes a base plate 1, and an adjustment and expansion mechanism is provided on the top of the base plate 1.

[0021] In this embodiment, the adjustment and expansion mechanism includes a support leg 2 fixedly installed on the top of the base plate 1, a bed frame 3 is fixedly installed on the top of the support leg 2, a brake motor 4 is fixedly installed on the top of the base plate 1, a rotating shaft 5 is fixedly installed on the output shaft of the brake motor 4, and a movable groove is opened at the bottom of the bed frame 3. The rotating shaft 5 is rotatably connected to the bed frame 3 through the movable groove, so that the brake motor 4 can drive the rotating shaft 5 to rotate.

[0022] Among them, a driving bevel gear 6 is fixedly installed on the top of the rotating shaft 5, and a driven bevel gear 7 is meshed with the top of the driving bevel gear 6. A rotating rod 8 is fixedly installed inside the driven bevel gear 7. A fixing groove is opened inside the driven bevel gear 7. The driven bevel gear 7 is fixedly connected to the rotating rod 8 through the fixing groove, so that the driven bevel gear 7 can drive the rotating rod 8 to rotate.

[0023] In this embodiment, threaded rods 9 rotatably connected to the bed frame 3 are fixedly installed on the left and right sides of the rotating rod 8, and the outer side of the threaded rod 9 is threadedly connected to a threaded block 10. Two sections of threaded grooves in opposite directions are provided on the outer sides of the two threaded rods 9. The threaded block 10 is threadedly connected to the threaded rod 9 through the threaded grooves, which facilitates the movement of the threaded block 10 on the outer side of the threaded rod 9.

[0024] Among them, an extended bed 11 movably connected to the bed frame 3 is fixedly installed on the outer side of the threaded block 10, and through holes are opened on the left and right sides of the bed frame 3. The extended bed 11 is movably connected to the bed frame 3 through the through holes, which facilitates the extended bed 11 to move inside the bed frame 3. A limiting rod 12 slidably connected to the bed frame 3 is fixedly installed on one side of the extended bed 11.

[0025] In this embodiment, the inner top wall and the inner bottom wall of the bed frame 3 are both provided with limiting grooves, and the limiting rod 12 is movably connected to the bed frame 3 through the limiting grooves, which is convenient for limiting the limiting rod 12. An armrest frame 13 is fixedly installed on the top of the bed frame 3, and a headrest 14 is fixedly installed on the top of the bed frame 3.

[0026] It should be noted that the expandable medical operating table can drive the threaded rod 9 to rotate by using the brake motor 4, the rotating shaft 5, etc. through the setting of the adjustment and expansion mechanism. The outer threaded block 10 starts to move under the limit of the limit rod 12 and the expansion bed 11, so that the two expansion beds 11 move out of the bed frame 3 at the same time. After the expansion bed 11 is extended, the surgical instruments or other objects can be placed on the expansion bed 11, which is convenient for taking during the operation. The brake motor 4 is used to reverse, so that the threaded rod 9 can be reversed, so that the expansion bed 11 moves to the inside of the bed frame 3, which is convenient for recovering the expansion bed 11, greatly improving the flexibility and use effect of the device.

[0027] The working principle of the above embodiment is:

[0028] The expandable medical operating table is used by firstly making the patient lie on the top of the bed frame 3, with the head on the headrest 14, and the hands on the top of the armrest 13, and then the operation can be performed. When the bed frame 3 needs to be expanded, the brake motor 4 is first started, and the brake motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the active bevel gear 6 and the driven bevel gear 7 to rotate, and then the driven bevel gear 7 drives the rotating rod 8 and the threaded rod 9 to rotate in turn, and the threaded block 10 outside the threaded rod 9 starts to move under the limit of the limit rod 12 and the expansion bed 11, and the threaded block 10 moves. The extension bed 11 is driven to move. Under the action of the two threaded rods 9, the two threaded blocks 10 begin to move away from each other, so that the two extension beds 11 move out of the bed frame 3 at the same time. After the extension bed 11 is extended, surgical instruments or other objects can be placed on the extension bed 11, which is convenient for taking during the operation. When the extension bed 11 is used, the brake motor 4 is started to reverse, which can reverse the threaded rod 9 and move the extension bed 11 to the inside of the bed frame 3, so that the extension bed 11 can be recovered conveniently, which greatly improves the flexibility and use effect of the device.
