It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.

[0020] As Figures 1 to 3 shown, this embodiment provides an expander for orthodontics in the oral cavity. The expander includes an expander rubber tube 1 and two expansion support components arranged at both ends of the expander rubber tube 1. The specific structure is as follows:

[0021] The expander rubber tube 1 is connected to an external expansion support gas source. An inflation tube 8 is connected to the middle of the expander rubber tube 1, and an air delivery tube 9 connected to the external gas source is connected to the orifice of the inflation tube 8. Each expansion support component includes an expansion support latex ring 2, an expansion support latex capsule 3, an expansion support rubber frame 4, and a built-in expansion support component. The expansion support rubber frame 4 is sleeved on the expansion support latex ring 2, and the expansion support latex capsule 3 is embedded in the expansion support latex ring 2. The built-in expansion support component includes a rubber ring 11 connected to the expansion support rubber frame 4 and a built-in airbag 10 movably arranged inside the rubber ring 11. The rubber ring 11 is fixedly connected to the inside of the expansion support rubber frame 4. After the built-in airbag 10 is inflated, it expands and supports against the inner wall of the rubber ring 11. An oral airbag 5 is also arranged inside the expansion support latex ring 2 and on the side close to the other expansion support rubber frame 4. The oral airbag 5 is connected to the expander rubber tube 1. The inflation tube 8 can deliver gas to expand and support the oral airbag 5 and the built-in airbag 10. Through the gas delivery of the expander rubber tube 1, the built-in airbag 10 can be inflated. The inflated built-in airbag 10 can expand and support inside the expansion support rubber frame 4. The expansion support rubber frame 4 can expand and support in the patient's oral cavity to replace the mechanical structure for expansion support. The inflated built-in airbag 10 uses its own elasticity to avoid over-expansion and damage to the patient's oral cavity. In this structural setting, when the expansion support latex capsule 3 is elastically embedded inside the oral expansion support latex ring 2 and the expansion support rubber frame 4, the inflated built-in airbag 10 can expand and support inside the expansion support rubber frame 4, and at the same time can expand and support the wrapped expansion support latex capsule 3 and the oral expansion support latex ring 2. The softness of the expansion support latex capsule 3 and the oral expansion support latex ring 2 can expand the oral cavity and avoid the conventional expander from prying open in the patient's oral cavity.

[0022] In a specific embodiment, an oral expansion ring 6 is further provided on the outer side of one of the expansion rubber frames 4. A folding rubber sleeve 7 is fixed inside the oral expansion ring 6. The folding rubber sleeve 7 can be inflated and unfolded on one side of the patient's oral cavity under the expansion action of the oral airbag 5. In this structural arrangement, the oral expansion ring 6 is fixedly connected to one side of the oral airbag 5, so that the folding rubber sleeve 7 is folded on the oral expansion ring 6. When the air supply pipe 8 delivers gas to inflate and expand the oral airbag 5 and the built-in airbag 10, the oral airbag 5 can expand and support the oral expansion ring 6 and the folding rubber sleeve 7. The oral expansion ring 6 and the folding rubber sleeve 7 can be inflated and unfolded on one side of the patient's oral cavity. The rubber tube 1 of the expander can maintain the horizontal oral distance. The oral expansion ring 6 and the folding rubber sleeve 7 expand on the cheek on one side of the oral cavity for expansion. The doctor can treat the horizontal oral tooth distance in the rubber tube 1 of the expander.

[0023] In a specific embodiment, a rubber insertion end 13 is provided at the air filling port inside the oral airbag 5.

The rubber insertion end 13 is connected and installed on the oral airbag 5 in a communicating manner. The connecting pipe 12 can be connected and installed on the rubber insertion end 13 in a communicating manner. The other end of the connecting pipe 12 is fixedly connected to the rubber tube 1 of the expander. The oral airbag 5 is inflated through the rubber insertion end 13 and the connecting pipe 12. Preferably, the connecting pipe 12 and the rubber insertion end 13 are connected by a rubber elastic plug; the oral airbag 5 is communicated with the rubber tube 1 of the expander through the connecting pipe 12 and the rubber insertion end 13. The connecting pipe 12 is elastically plugged inside the rubber insertion end 13 by itself, which is convenient for the doctor to disassemble the rubber insertion end 13 and the connecting pipe 12. At the same time, the rubber insertion end 13 of the expander can be connected to the rubber tube 1 of the expander for air inflation connection. For different patients, the oral airbag 5 always maintains an expanded state through the rubber insertion end 13 of the expander. The oral airbag 5 can be used for minors, expanding the scope of use, and the doctor does not need to maintain a fixed hand-held state during the oral treatment process, avoiding excessive fatigue.

[0024] In a specific embodiment, the air supply pipe 8 is used for gas delivery. When the oral airbag 5 and the built-in airbag 10 are inflated and expanded, the oral airbag 5 can expand and support the oral expansion ring 6 and the folding rubber sleeve 7, so that the oral expansion ring 6 and the folding rubber sleeve 7 can be inflated and unfolded on one side of the patient's oral cavity. The inflated built-in airbag 10 can be unfolded and supported inside the expansion rubber frame 4. The expansion rubber frame 4 can expand in the patient's oral cavity to replace the mechanical structure for expansion. The doctor can treat the horizontal oral tooth distance in the rubber tube 1 of the expander.

[0025] In a specific embodiment, the connecting pipe 12 is elastically plugged inside the rubber insertion end 13 by itself, which is convenient for the doctor to disassemble the rubber insertion end 13 and the connecting pipe 12; the rubber insertion end 13 of the expander is connected to the rubber tube 1 of the expander for air inflation connection.
