Description

Adjustable mouth gag

The technical field is as follows:

the utility model relates to the field of oral care, in particular to an adjustable mouth gag.

Background art:

caries is a very common oral infectious disease that severely affects human oral and general health. The fourth national oral health epidemiological survey result shows that the caries rate of 5-year-old children in China is 71.9 percent. The child caries has the characteristics of high caries rate, early onset, high caries development speed and wide range, the pathogenesis of the child caries is closely related to factors such as the form of an affected tooth, feeding habits, food and the like, but clinical symptoms are not obvious and are easy to ignore, the optimal treatment time is delayed, the early stage can influence the chewing function of an affected child, the tooth body structure and oral soft tissues are damaged, and complications such as pulpitis, chronic periapical periodontitis, other tissue infection and the like can be seriously caused.

For ill-done children who need caries treatment, the mouth gag is a very important medical auxiliary instrument. The dental caries treatment instrument can enlarge the operation visual field in the oral cavity in the dental caries treatment process and reduce the accidental scratch of skin and mucous membrane, but the dental caries treatment instrument brings convenience to the oral treatment of doctors and also increases the risk of airway safety management. The primary task of airway management is to prevent aspiration and error-level retrying during the use of the mouth gag. Once a wrong smoking and smoking accident occurs, not only the smooth implementation of the treatment is concerned, but also the life safety of the infant may be endangered.

The existing mouth gag has only a fixed model and is difficult to match with the mouth opening degree of a child patient, thereby not only influencing the smooth progress of caries treatment, but also increasing the risk of aspiration and kidney failure.

The utility model has the following contents:

the utility model provides an adjustable mouth gag to overcome the defects in the prior art.

The application provides the following technical scheme:

the utility model provides an adjustable mouth gag, it includes the mouth gag main part, its characterized in that: the mouth gag is characterized in that a pair of groove bodies are arranged on the mouth gag main body, a transverse groove is arranged on the mouth gag main body between the pair of groove bodies, a bidirectional jacking device is arranged in the transverse groove, and two ends of the bidirectional jacking device are respectively inserted into one groove body to form jacking corresponding matching with the groove wall on one side of the groove body.

On the basis of the technical scheme, the following further technical scheme can be provided:

the mouth gag main body is provided with a hand-held part.

The bidirectional jacking device comprises a barrel, wherein two ends of the barrel are respectively in threaded connection with an ejector rod, the direction of threads on the two ejector rods is opposite, and one end of each ejector rod is inserted into the corresponding groove body to be correspondingly matched with the groove wall.

And a top plate is arranged at the end part of the ejector rod in the groove body.

The transverse groove is provided with an expansion part which is distributed corresponding to the cylinder body.

Utility model advantage:

the tooth-inserting groove is simple in structure and convenient to use, the groove walls of the groove body are pushed by the bidirectional jacking device to be opened in an arc shape, so that teeth of young children can be conveniently and smoothly inserted into the groove body, thereby ensuring the smooth progress of caries treatment and reducing the risk of accidental injury, aspiration and aspiration of adjacent soft and hard tissues.

Description of the drawings:

fig. 1 is a schematic structural view of the present invention.

The specific implementation mode is as follows:

as shown in figure 1, the adjustable mouth gag comprises a mouth gag main body 1 made of silica gel, wherein the mouth gag main body 1 is distributed in an inverted trapezoid shape, and four corners of the mouth gag main body are transited through round corners. An arc-shaped handheld part 5 is arranged on the top of the mouth gag main body 1. The hand-held part 5 and the mouth gag main body 1 are of an integrated structure. The traction rope is pulled in the hand of the medical staff by tying the traction rope on the handheld part 5, so that the mistaken swallowing is prevented and treated.

The two ends of the mouth gag main body 1 are respectively provided with a groove body 2, and the groove bodies 2 and the bevel edges of the ends of the mouth gag main body 1 on the adjacent side are distributed in parallel. The mouth gag main body 1 between the two groove bodies 2 is provided with a transverse groove 3, the middle part of the transverse groove 3 is provided with an enlarged part 3a with enlarged groove wall interval, and the enlarged part 3a and the transverse groove 3 are coaxially distributed.

The bottom in the transverse groove 3 is provided with a coaxial distribution bidirectional jacking device 4. The bidirectional jacking device 4 comprises a cylinder body 4a distributed in the enlarged part 3a, two ends of the cylinder body 4a are respectively in threaded connection with a push rod 4b, the direction of threads on the two push rods 4b is opposite, and one end of each push rod 4b is inserted into the corresponding groove body 2 and welded with a top plate 4c in contact with the groove wall at the end part. The push rods 4b at both ends can be simultaneously extended or retracted by rotating the cylinder 4 a. The groove wall of the groove body is opened in an arc shape by pushing the groove wall of the groove body by the push rod 4b, so that the teeth of the child can be smoothly inserted into the groove body. Once a tooth is inserted into the groove body, the groove body can be completely unfolded to facilitate the insertion of other teeth.

Since the two-way jacking device 4 is arranged at the bottom in the transverse groove 3, the top plate 4c at one end of the jacking rod is also arranged at the bottom of the groove body 2. So that it will not be affected by the teeth inserted into the housing 2.
