Description

Multi-angle adjustable mouth mirror

technical field

The invention relates to a multi-angle adjustable mouth mirror.

Background technique

The mouth mirror is one of the most commonly used small medical devices in oral clinical diagnosis and treatment. Its main functions are: pulling the patient's cheek and pushing the tongue to directly observe the lesion; gathering light to increase the visibility of the inspection site; The mirror reflects light to observe the hard-to-see areas, such as the upper teeth and the inside of the pulp cavity. However, at present, the body of the mouth mirror commonly used in clinical practice is connected to the handle through a fixed angle. Chair lights provide light. When using this kind of mouth mirror to observe the parts that are difficult to see directly, such as the buccopalatal side of the crown of the maxillary teeth, the mesial and distal neck, and the inside of the pulp cavity of the upper and lower teeth, it is often necessary to repeatedly adjust the angle of the mouth mirror, the patient's position and The angle of the lighting of the dental chair obviously affects the doctor's observation and operation, prolongs the treatment time and reduces the patient's comfort. Therefore, the mouth mirror with a fixed angle cannot realize observation from more angles, and cannot be well adapted to various usage scenarios.

In addition, during the use of the mouth mirror, due to the temperature difference between the mouth mirror and the oral cavity, it will cause fogging on the mirror surface, which will affect observation; When the enamel and dentin are damaged, decay, temporary sealant, enamel or dentin fragments stick to the mirror surface of the mouth mirror with the water mist, which obviously affects the doctor's observation and operation. At present, when solving the problem of fogging on the mirror surface and cleaning the mirror surface, the mouth mirror needs to be taken out from the patient's mouth and wiped with a sterile cotton ball. After treatment in this way, the doctor needs to adjust the angle of the mouth mirror again to observe or treat the ward, and repeatedly "take out the mouth mirror—wipe—put the mouth mirror into the mouth and adjust the angle", which reduces the efficiency of treatment and increases the patient's treatment time. time and discomfort. Moreover, after simply wiping, the mirror surface is prone to fog again, and it is also easy to stick to decay, temporary sealant, enamel or dentin again.

The above problems should be considered and solved during the use or design of mouth mirrors.

Contents of the invention

The internal pulp cavity of the upper and lower jaw teeth, etc., to achieve a wider angle of observation. At the same time, the mist, decay, filling materials, dentin or enamel debris on the mirror surface can be quickly removed by air jet, which solves the need to repeatedly take out the mirror from the patient's mouth and wipe it when using the existing mouth mirror, so as to improve the efficiency of treatment .
