[0025] See also Figure 1 , an auxiliary fixing device for anesthesia position, the device comprises an operating bed 10, a pushing mechanism 20 is arranged on both sides of the operating bed 10, the pushing mechanism 20 comprises a square groove 21 opened on both sides of the operating bed 10, a square block 22 is slidably connected inside the square groove 21, the shape of the square block 22 corresponds to the square groove 21, the square block 22 can slide inside the square groove 21, a connecting arm 23 is fixedly installed on the outside of the square block 22, and a support plate 24 is rotatably connected between the two connecting arms 23. In this embodiment, the support plate 24 can be driven to move by the connecting arm 23 during the sliding process of the square block 22 inside the square groove 21, so that when the parturient is anesthetized, by pushing the support plate 24 forward to move, when the parturient bends her legs, the soles of her feet have a force point under the action of the support plate 24, and the parturient can easily maintain such an anesthesia injection state. Save physical strength for the parturient.

[0026] Further, in order to better allow the support plate 24 to move, a rotating gear 25 is rotatably connected at the rear side of the square block 22 and located inside the square slot 21, a fixed tooth plate 26 is fixedly installed inside the square slot 21, and a rotating shaft passing through the square block 22 and the connecting arm 23 is fixedly installed in the axial direction of the rotating gear 25, and the rotating shaft is fixedly installed on the side away from the connecting arm 23. The adjusting mechanism 30 is used to drive the rotating shaft to rotate, and the rotating shaft drives the rotating gear 25 to rotate. Since the rotating gear 25 is meshed and connected with the fixed tooth plate 26, the rotating gear 25 will move along the fixed tooth plate 26 inside the square slot 21. Then, the square block 22 and the support plate 24 can be driven to move. Thereby, it is convenient to control the front and rear movement of the support plate 24, and while achieving the effect of maintaining the position of the parturient, it can also meet the needs of parturients of different heights to use the auxiliary device, thereby improving the practicality of the auxiliary device.

[0027] Preferably, Figure 2 As shown, there is a connecting shaft between the two rotating gears 25. By setting the connecting shaft, the rotating gears 25 on both sides can be rotated synchronously by setting an adjustment mechanism 30 on one side of the operating table 10. This setting can avoid the problem of the support plate 24 being "stuck" during the movement due to different feeding amounts of the rotating gears 25 on both sides. That is, the smoothness of the pushing mechanism 20 when moving is improved.

[0028] like Figure 3 As shown, because the parturient may push the support plate 24 backward when applying force to the support plate 24, an adjustment mechanism 30 is provided to prevent the support plate 24 from retreating. The adjustment mechanism 30 includes a rotating handle 31 fixedly connected to the rotating shaft, and also includes a limit plate 32 fixedly mounted on the connecting arm 23 and designed coaxially with the rotating shaft. A retractable positioning rod 33 is fixedly mounted on the rotating handle 31, and the positioning rod 33 can be inserted into a limiting hole 34 in the limiting plate 32. In this embodiment, by manually controlling the positions of the positioning rod 33 and the limiting hole 34, when the positioning rod 33 is pulled out of the limiting hole 34, the rotating handle 31 can rotate freely, and then cooperate with the rotating shaft to drive the rotating gear 25 inside the square groove 21, and the position of the support plate 24 can be completely adjusted; when it moves to the specified position (that is, it can provide force to the parturient), the positioning rod 33 is released, and the positioning rod 33 is reinserted into the limiting hole 34, so that the rotation of the rotating handle 31 can be limited, and then the rotation of the rotating gear 25 can be limited. The support plate 24 is kept in the same position on the operating bed 10. Therefore, when the parturient applies force, the problem of the support plate 24 retreating can be avoided, which causes the parturient to "push in the air".

[0029] After the injection anesthesia work is completed, the existence of the support plate 24 will affect the subsequent surgical operation, so Figure 4 and Figure 5 As shown, the square block 22 is set to be an elastic material, which can be rubber; and the tail of the square groove 21 (the tail of the operating bed 10) is higher than the head (the head of the operating bed 10), so when the square block 22 is set at the tail of the square groove 21, the restriction force of the square groove 21 on the square block 22 will be reduced. When the drag plate 24 is not needed, the square block 22 can be moved to the tail of the square groove 21, and the connecting arm 23 is forced to bend, and the connecting arm 23 drives the square block 22 made of elastic material to rotate ninety degrees inside the square groove 21, and the connecting arm 23 changes from a state perpendicular to the operating bed 10 to a state parallel to the operating bed 10, so that the support plate 24 increases the length of the tail of the operating bed 10. The use length of the operating bed 10 is increased for subsequent surgical work.

[0030] Furthermore, a support member (not shown) for carrying the support plate 24 may be provided at the rear of the operating bed 10 to increase the bearing capacity of the support plate 24 when the support plate 24 is designed to be parallel to the operating bed 10 .

[0031] Moreover, if Figure 6 and Figure 7 As shown, in order to better realize the use of the support plate 24, a control mechanism 40 is provided at the rotation connection between the connecting arm 23 and the support plate 24, and the control mechanism 40 includes a limit shaft 41 fixedly connected to the support plate 24 axis, a limit ring 42 sleeved on the limit shaft 41 is fixedly installed on the connecting arm 23, a convex rod 43 is fixedly installed on the limit shaft 41, and a group of blocking rods 44 symmetrically distributed and corresponding to the convex rods 43 are fixedly installed inside the limit ring 42. In this embodiment, when the support plate 24 is placed vertically with the operating bed 10, the convex rod 43 contacts the blocking rod 44 below, and the blocking rod 44 provides resistance to the counterclockwise rotation of the convex rod 43, so as to avoid the problem of the support plate 24 rotating when the parturient applies force to the support plate 24. When the support plate 24 is parallel to the operating bed 10, the support plate 24 can be rotated 180 degrees clockwise to increase the length of the tail of the operating bed 10.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
