[0033] In one embodiment of this utility model, an opening device is provided, see [link to relevant documentation]. Figures 1 to 5 As shown, the mouth opener includes a lip insert 1 and a saliva suction tube, wherein:

[0034] The lip insert 1 includes a left opening 11, a right opening 13, and a central connecting portion 12 connecting the left opening 11 and the right opening 13. The left opening 11 and the right opening 13 each have grooves on their outer surfaces for fixing the lips. The central connecting portion 12 also has a groove on its outer surface. The grooves of the left opening 11 and the right opening 13 communicate with the groove of the central connecting portion 12, with the openings of the grooves facing outwards. When the mouth opener is in use, the central connecting portion 12 is located below the left opening 11 and the right opening 13, and is positioned outside the lips.

[0035] See Figure 1-2 The left opening 11, the right opening 13, and the middle connecting part 12 are all U-shaped. The lower part of the left opening 11 and the lower part of the right opening 13 are connected to the upper two ends of the middle connecting part 12. The U-shaped opening of the middle connecting part 12 is recessed away from the left opening 11 and the right opening 13. The U-shaped openings of the left opening 11 and the right opening 13 are opposite each other.

[0036] The saliva suction tube includes a first tube 2 and a second tube 3. The first tube 2 includes a left tube body, a right tube body, a first connecting part 25, and a second connecting part 26.

One end of the second tube 3 is connected to the first connecting part 25, and the other end of the second tube 3 extends out of the groove of the middle connecting part 12 and extends forward away from the lip insert 1. That is, one end of the second tube 3 is located in the groove of the middle connecting part 12, and the other end of the second tube 3 is located outside the lip insert 1. The other end of the second tube 3 is used to connect with an external saliva suction device so that the saliva inside the first tube 2 is discharged from the second tube 3.

[0037] When using the mouth opener in this example, the left tube is positioned between the lower teeth and the skin on one side, and the other end of the left tube can abut against the hard palate inside the mouth; the right tube is positioned between the lower teeth and the skin on the other side, and the other end of the right tube can abut against the hard palate inside the mouth. The second connecting part 26 can abut against the tongue, thus pressing down on the tongue to prevent it from sticking out. This allows for the suction of saliva (water, saliva) from the inside and outside of the lower teeth and between the teeth and lips, allowing the liquid inside the mouth to flow out of the mouth without leaving any residue. The mouth opener can help patients, as it is tiring to open their mouths. It can also better support the mouth and prevent the mouth from being passively closed, while blocking and protecting the lips and tongue from injury.
