device for oral examination

Abstract

The invention relates to an oral cavity examination apparatus, which comprises sleeves, a sliding rod, an image collection device and push rod mechanisms, wherein annular LED lamps are arranged on the end faces of the lower ends of the sleeves. Each of the push rod mechanisms comprises a sliding block, an annular flange, a compression spring and a radial pressing block, wherein an ejection inclined plane is formed in the lower part of the inner wall of each radial pressing block; the ejection inclined planes can abut against the upper parts of the sliding blocks; and by virtue of the ejection inclined planes, the sliding blocks are pushed to move towards the lower ends of the sleeves when the radial pressing blocks move inwards in a radial direction, so that the image collection device, which is hidden in the sleeves, is pushed out of an opening. Conductive blocks are arranged at the upper parts of the annular flanges in the axial directions of the compression springs; the conductive blocks are electrically connected to the LED lamps by virtue of lead wires; conductive needles are inserted in the sliding blocks in a vertical direction; the first end parts of the conductive needles extend out of the lower end faces of the sliding blocks and the second end parts of the conductive needles are connected to a power supply; and the first end parts get into contact with the conductive blocks when the compression springs are under a compressed state. The oral cavity examination apparatus is simple in structure and convenient to operate, and various parts in an oral cavity can be clearly observed conveniently.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an oral cavity inspection device. Background technique [0002] Regular dental check-ups have different meanings for different people. For example, in childhood, caries and misaligned teeth are the main problems. Parents should take their children to have check-ups every six months; In some people's minds, the idea that toothache is not a disease still exists, so that caries and periodontal disease are allowed to develop. As a result, the life span of the tooth is much shorter than its life. Therefore, adults should have a dental check-up every year and clean it every six months. Primary teeth: In old age, the main problems are tooth loss and tooth restoration. Residual roots and crowns should be dealt with in time to prevent them from becoming lesions and causing damage to the heart, kidneys, and eyes. Therefore, the elderly should have oral examinations every six months. [0003] However...

AI Technical Summary

Problems solved by technology

[0003] However, due to the limited space in the oral cavity, and the tongue often blocks the line of sight, it is difficult to observe carefully the various positions in the oral cavity

In addition, for the teeth near the back of the mouth, even if they are not blocked by the tongue, they are difficult to see clearly due to the lack of light

In the current oral examination, it is often necessary for medical staff to operate multiple instruments at the same time, which increases the workload of medical staff and brings pain to patients
