DETAILED DESCRIPTION

[0024] The utility model is now described in further detail with reference to the accompanying drawings.

[0025] See also Figures 1 to 5 The utility model provides a technical solution: an oral mouth opener, comprising a connecting rope 1 and two mouth openers, two mouth openers are respectively installed at both ends of the connecting rope 1, each mouth opener comprises an upper expansion plate 2 and a lower expansion plate 3, a telescopic air bag 4 is arranged between the upper expansion plate 2 and the lower expansion plate 3, one side of the telescopic air bag 4 is connected to a catheter 5, the other end of the catheter 5 passes through the side of the lower expansion plate 3 and is connected to the connecting end of the inflated balloon 7, and a deflation knob 8 is arranged on one side of the connecting end;

[0026] The upper expansion board 2 and the lower expansion board 3 are made of medical grade plastic. L-shaped clips 9 are symmetrically fixed at the bottom of the lower expansion board 3 and the top of the upper expansion board 2. A T-shaped clip 10 is clamped between every two symmetrical L-shaped clips 9. A disposable bracket 11 adapted to the patient's molars is integrally formed on the surface of each T-shaped clip 10. A groove 12 for the patient's molars to be placed is opened in the middle of each disposable bracket 11.

[0027] Each upper expansion plate 2 and lower expansion plate 3 is provided with a cavity for installing a battery 13, a main auxiliary lighting lamp 14 is installed on the top of each cavity, and a secondary auxiliary lighting lamp 15 for auxiliary lighting of the patient's mouth is provided on the side wall of each upper expansion plate 2 and lower expansion plate 3. Considering that most of the mouth openers currently used in dentistry have a simple structure, and usually use opening pliers to open and support the patient's mouth, the structure is relatively complicated, the pliers handle is too long, which is inconvenient for medical staff to check and operate, and the weight of the pliers makes it extremely uncomfortable for patients to wear them. The utility model uses two mouth openers to support the teeth on both sides of the patient respectively. And because of the split structure, a reserved area for the dentist to operate is left between the two mouth openers, and the upper expansion plate 2 and the lower expansion plate 3 constituting the mouth opener are made of light-weight medical-grade plastic, which can ensure that the weight of the device does not cause pressure on the patient's teeth like opening pliers. At the same time, considering that a part of the optical fiber is blocked by the mouth opener during the internal examination of the oral cavity, the main auxiliary lighting 14 and the auxiliary auxiliary lighting switch will be turned on by the button 6 at this time, so as to illuminate the inside of the patient's oral cavity. When the device is used, the disposable tray is taken out and connected with the L-shaped card strip 9 through the T-shaped card strip 10 to complete the installation, and then the two openings are The device is inserted into the patient's oral cavity so that the molars on both sides of the patient's oral cavity are respectively placed in the grooves 12 of the disposable support plate. At this time, the patient's molars are located inside the grooves 12. Compared with the existing equipment with a flat support surface, the concave design of the disposable support plate of the device prevents the molars from sliding with the contact surface of the device and causing position displacement, and the stability is higher. Then the medical staff presses the inflated balloon 7, and the inflated balloon 7 transports the external gas to the inside of the telescopic airbag 4. As the gas enters the telescopic airbag 4, it expands. At this time, the distance between the upper expansion plate 2 and the lower expansion plate 3 will be driven to expand by the inflated telescopic airbag 4. During the expansion process, the L-shaped guide The rod 16 cooperates with the guide ring 17 for guidance, and the supporting process is completed at this time. When auxiliary lighting of the patient's mouth is needed to ensure the field of vision, the start button 6 is pressed, and then the main auxiliary lighting lamp 14 and the auxiliary auxiliary lighting lamp 15 are turned on to supplement the internal environment of the mouth. After the device is used, the deflation knob 8 can be loosened to allow the gas in the telescopic airbag 4 to leak, so that the expanded upper expansion plate 2 and the lower expansion plate 3 are contracted. At this time, the device is taken out. The inflation balloon 7 and the deflation knob 8 are similar to the existing technology, so the detailed internal structure is not described in detail in this article. The inflation balloon 7 similar to the blood pressure monitor can be inflated and deflated.

[0028] Among them, L-shaped guide rods 16 are fixedly installed on both sides of each lower expansion plate 3, and a guide ring 17 is sleeved on the outside of each L-shaped guide rod 16, and the guide ring 17 is fixedly installed on the side of the upper expansion plate 2, and the upper end of each L-shaped guide rod 16 is threadedly connected to the disassembly bolt 18. The L-shaped guide rod 16 and the guide ring 17 are arranged to guide the expansion of the upper expansion plate 2 and the lower expansion plate 3, thereby avoiding the situation where there is no corresponding guide structure when the telescopic airbag 4 drives the upper expansion plate 2 and the lower expansion plate 3 to expand, resulting in position displacement of the upper expansion plate 2 and the lower expansion plate 3 when they expand.

[0029] Among them, each telescopic airbag 4 is fixed with a connecting sleeve 19 at both ends, and a connecting rod 20 is connected through the inside of each connecting sleeve 19, and L-shaped blocks 21 are fixed at both ends of each connecting rod 20, and each L-shaped block 21 is fixed by a fixing bolt 22, and the fixing bolt 22 is installed in the upper expansion plate 2 and the screw holes opened on the surface of the upper expansion plate 2. The connection rod 20 is provided to install the two ends of the telescopic airbag 4, and because the connecting cover is installed by the L-shaped block 21 and the fixing bolt 22, it is convenient for the user to disassemble, maintain or replace the telescopic airbag 4 at a later time.

[0030] Among them, the T-shaped clip 10 and the disposable support block 11 are both made of translucent materials. By setting the disposable support block 11 and the L-shaped clip 9 to be translucent materials, it is convenient for the light of the main auxiliary lighting lamp 14 to illuminate the internal environment of the oral cavity through the translucent material.

[0031] Among them, the other side of the upper expansion board 2 and the lower expansion board 3 are provided with countersunk holes for placing control buttons 6, and each button 6 is connected to the corresponding battery 13 circuit through a wire, and the battery 13 is also connected to the main auxiliary lighting lamp 14 and the auxiliary auxiliary lighting lamp 15 circuit through a wire. By setting the battery 13, the main auxiliary lighting lamp 14 and the auxiliary auxiliary lighting lamp 15 are powered.

[0032] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
