Description

Technical Field

[0001] The utility model relates to the field of children's oral examination, in particular to an oral opening device for children. Background Art

[0002] Dental examinations and treatments are limited in operating space, especially in the posterior teeth area where the examination and treatment area is deeper. The tongue, oral cavity and lingual and buccal sides of the teeth fit closely together. The treatment operation space is small and difficult to fix, and it is impossible to ensure the appropriate distance between the two sides of the teeth at the same time. Treatment can easily damage the oral mucosa and tongue. If the patient keeps his mouth open for a long time, it can easily lead to facial muscle spasms and discomfort in the temporomandibular joint area. This not only affects the examination and treatment effect, but also affects the consultation experience. Therefore, when the doctor examines and treats the child, he needs to use an oral opener to open the patient's mouth to an appropriate extent and fix it, and then perform the examination and treatment. At the same time, an oral saliva suction tube will be used during the oral operation. Generally, the oral saliva suction tube will be connected to a negative pressure suction tube to suction the corresponding blood, saliva and water produced during the treatment to ensure a clear field of vision and normal oral treatment.

[0003] At present, the mouth openers widely used in my country's oral medical field are mostly fixed in the mouth by doctors. Due to the large amount of saliva and poor cooperation of children, the mouth openers are prone to slipping. Due to the unstable retention of the mouth opener in the mouth, the doctor needs to support and fix it with one hand when using it, which not only distracts the doctor's attention but also increases the doctor's burden. On the other hand, some extraoral fixed mouth openers have a small contact area with the teeth and are hard. Generally, they only contact 1 to 2 teeth. If children use them for a long time, some teeth will feel uncomfortable and the teeth will be damaged. Some mouth fixers with straws cannot adjust the position of the fixed suction tube, and the liquid in the mouth cannot be completely sucked out, affecting the treatment effect. Therefore, how to solve the above-mentioned technical problems and defects has become a key issue that needs to be solved.

[0004] In summary, there is an urgent need for an opener that can fully absorb the saliva in the oral cavity while opening the mouth. Utility Model Content

[0052] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0053] The utility model provides a mouth opener for children. Figure 1 , comprising a pliers body 1, said pliers body 1 comprising two pliers rods 2 and a jaw 11 of adjustable size located between the working ends of the two pliers rods 2, the working ends of the two pliers rods 2 are provided with tooth brackets 3 extending perpendicularly to the pliers body 1 and with the notches facing each other; a rotatable saliva suction mechanism 4 is further provided at the connection between the two pliers rods 2, said saliva suction mechanism 4 being suitable for adjusting and clamping a saliva suction tube 44. For illustration, the tooth brackets 3 facing each other refer to, for example, Figure 1 In the state shown, the notch of the left tooth bracket 3 faces leftward, and the notch of the right tooth bracket 3 faces rightward. Figure 1 The illustrated state shows the present invention in a horizontal position. To use the present invention, the jaws 11 are placed vertically, with one bracket 3 holding the upper teeth and the other bracket 3 holding the lower teeth. The jaws 11 are then adjusted to open the mouth wider, and the saliva suction mechanism 4 is used to aspirate saliva. This arrangement allows the present invention to aspirate saliva from the mouth in all directions while opening the mouth.

[0054] The utility model provides a child's oral opening device, referring to Figures 1 to 3The pliers 2 include a body 22 and a head 21, with the bracket 3 positioned at the working end of the head 21. The body 22 of one of the pliers 2 is provided with a fixing bar 23 extending toward the body 22 of the other pliers 2, while the body 22 of the other pliers 2 is provided with a sliding groove 24 slidably connected to the fixing bar 23. For illustration, the closer the two heads 21 are, the farther the two bodies 22 are, and the smaller the opening of the jaws 11 is, and vice versa. Before the pliers 1 are inserted into the mouth, the jaws 11 are typically closed or slightly open, at which point the distance between the two bodies 22 is greater. After the pliers 1 are inserted deeply into the mouth and the bracket 3 is positioned against the tooth, the distance between the two bodies 22 is gradually reduced by grasping and squeezing the two bodies 22 with one hand. This gradually increases the distance between the two heads 21, and the jaws 11 gradually opens. As the distance between the two jaws 22 gradually decreases, the fixing strip 23 gradually moves toward the slide groove 24 and enters the slide groove 24 until the mouth is opened to the appropriate size. The fixing strip 23 and the slide groove 24 are then locked to the size of the jaws 11. At this time, the mouth can be kept open without continuously squeezing the two jaws 22. The present invention achieves the maintenance of the size of the jaws 11 through the above arrangement, which not only improves the comfort of the child, but also greatly frees up the doctor's hands, improving the efficiency of oral examination and treatment.
