Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in Figure 1:

A dental mouth opening device includes a fixing plate 1 .

In this embodiment: at present, when performing opening operations on patients with oral diseases, pliers are often used for operation, but when the medical staff holds the rear end of the pliers to open the front support plate, so as to open the patient's mouth , in order to keep the patient's mouth open, it is necessary for medical staff to continue to hold it with their hands, which will occupy the medical staff's hands and affect the medical staff's subsequent treatment operations.

Going further:

An opening assembly 2 is mounted on the fixing plate 1 .

Going a step further:

As shown in Figure 1, Figure 2 and Figure 3:

In combination with the above content: the opening assembly 2 includes a fixed block 21, a rotating gear 22, an incomplete gear 23, a rotating rod 24, an opening plate 25 and a connecting rod 26. The inner side of the fixed plate 1 is provided with a circular through hole, and the through hole A fixed block 21 is fixedly connected inside, a rotating gear 22 is rotatably connected to the outside of the fixed block 21, and an incomplete gear 23 is meshed and connected to the outside of the rotating gear 22. The outer side of the gear 23 is fixedly connected with a rotating rod 24, and the other end of the rotating rod 24 is rotatably connected with an opening plate 25 through the second rotating shaft. The rotating shaft is rotatably connected with the opening plate 25 , and the other end of the connecting rod 26 is rotatably connected with the fixed plate 1 through the fifth rotating shaft.

In this embodiment, when in use, the handle can be rotated to drive the rotating gear 22 to rotate. At this time, driven by the rotating gear 22, the incomplete gear 23 can be rotated, so that the incomplete gear 23 can be rotated by the handle. 23 drives the rotating rod 24 to rotate. Under the driving of the rotating rod 24, the opening plate 25 can be driven to open and close. At this time, the opening plate 25 can drive the connecting plate 35 to rotate, so that the effective opening of the patient's oral cavity can be realized.

It should be noted that the rotation direction of the opening plate 25 is related to the rotation direction of the rotation rod 24 , the rotation direction of the rotation rod 24 is related to the rotation direction of the incomplete gear 23 , and the rotation direction of the incomplete gear 23 is related to the rotation direction of the rotation gear 22 In relation, the direction of rotation of the rotating gear 22 is related to the direction of rotation of the handle.

Going a step further;

In an optional embodiment, the opening assembly 2 further includes an anti-skid pad 27 , and the outside of the opening plate 25 is fixedly connected with the anti-skid pad 27 .

In this embodiment: this can not only make the contact between the opening plate 25 and the patient's oral cavity more stable, and avoid slipping, but also through the anti-skid pad 27, the patient's oral cavity can be well protected, and the hard opening plate can be avoided during the opening process. 25 Causes damage to the patient's mouth.

It should be noted that the anti-skid pad 27 is made of medical silicone material with certain elasticity.

As shown in Figure 3 and Figure 4:

The dental mouth opening device further includes a limit component 3, the limit component 3 includes a sliding rod 31, a sliding plate 32, a spring 33 and a limit block 34, the inner side of the fixed plate 1 is provided with a groove, and the groove is slidably connected There is a sliding plate 32 , and the side of the sliding plate 32 close to the rotating gear 22 is fixedly connected with three limit blocks 34 arranged at equal distances. It is fixedly connected with one end of the three sliding rods 31 arranged at an equal distance. The sliding rod 31 slides in the three through holes opened on the fixed plate 1. The outer side of the sliding rod 31 is sleeved with a spring 33. The plate 32 is fixedly connected, and the other end of the spring 33 is fixedly connected to the fixed plate 1 .

In this embodiment: in this way, the limit block 34 can be driven by the sliding plate 32, and driven by the elastic force of the spring 33, the limit block 34 can be inserted into the tooth slot of the rotating gear 22, so that the limit block 34 can adjust the rotating gear. 22 to effectively limit the position. When the limit block 34 is not required to limit the rotating gear 22, only the sliding rod 31 needs to be moved, so that the sliding rod 31 drives the limit block 34 to move, so that the limit block 34 does not move. It is enough to contact the rotating gear 22 again, and when the sliding rod 31 is moved, it will drive the sliding plate 32 to move, so that the sliding plate 32 will squeeze the spring 33, so that the spring 33 is compressed and deformed. When the block 34 limits the rotating gear 22 , the sliding rod 31 is released at this time, so that the compressed spring 33 will rebound itself, so that the limiting block 34 can limit the rotating gear 22 again.

Further;

In an optional embodiment, the limiting assembly 3 further includes a connecting plate 35 , and the other ends of the three sliding rods 31 arranged at an equal distance are fixedly connected with the connecting plate 35 .

In this embodiment, by pulling the connecting plate 35, the three sliding rods 31 can be driven to move simultaneously, which saves time and effort and is easier to operate than directly pulling the sliding rods 31.

Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
