Description

Technical Field

[0001] This application relates to the technical field of stomatology, and more specifically, to a dilator device. Background Art

[0002] Oral dilators are usually instruments made of metal or plastic and are commonly used in orthodontic treatment for children. They can be used to expand the size of the upper and lower jaws, thus creating more space to correct abnormal tooth alignment or occlusion problems and facilitating dental examinations. The oral dilator proposed in the existing publication number CN210228091U has the advantages of simple and compact structure and convenient and fast use. In view of the above related technologies, the utility model inventors believe that there are still the following defects: The dilator in the comparative literature cannot be pinched by fingers. The fingers of medical staff need to be placed in the oral cavity of children, and then the arc-shaped occlusal part on one side is squeezed, resulting in inconvenient installation and disassembly. Moreover, after the dilator is installed, the inside of the oral cavity cannot be illuminated, and an additional lighting lamp is required. In view of this, we propose a dilator device. Summary of the Utility Model

Moreover, after the dilator is installed, the inside of the oral cavity cannot be illuminated, and an additional lighting lamp is required. When the dilator is installed in a child's oral cavity, medical staff can pinch the J-shaped frame with their fingers to elastically deform the two U-shaped elastic parts, thus facilitating the installation and disassembly of the dilator. The child's teeth bite on the bite bar, and the middle arc-shaped block and the side arc-shaped block are used to expand the child's teeth and lips, and expose the teeth. By threading the threaded rod along the connecting ring, the inside of the oral cavity can be illuminated through the LED lamp holder, facilitating the observation of the inner wall of the teeth.
