Multi-angle adjustable mouth mirror

Abstract

The invention provides a multi-angle adjustable mouth mirror which comprises a mirror body and a handheld part. The mirror body comprises a mirror surface, a mirror frame and a first supporting arm. The mirror surface is arranged in the mirror frame, the mirror frame is connected with one end of the first supporting arm, an outer thread is arranged at the other end of the first supporting arm, and the first supporting arm is connected with the handheld part through the outer thread. The handheld part comprises an arm seat, a rotating shaft, a second supporting arm, a push-pull rod, a handle body and an illumination button. By arranging the push-pull rod in the handheld part and controlling the push-pull rod to move back and forth, moving of the second supporting arm is achieved, and thus the angles of the first supporting arm and the mirror surface are adjusted; the illumination button is arranged on the handheld part, and thus the mirror surface is illuminated. According to the multi-angle adjustable mouth mirror, the included angle between the mirror body and the handheld part can be quickly adjusted, multi-angle observation on all the faces of the dental crown and the interior of the medullary space can be achieved without adjusting the posture of a patient, and thus the demands of a user for the operation of positioning root canal orifices and the like in baked porcelain crown preparation, dental caries cavity making and root canal therapy processes can be better met.

Description

technical field [0001] The invention relates to a multi-angle adjustable mouth mirror. Background technique [0002] 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 ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a multi-angle adjustable mouth mirror, which solves the problem that when the existing fixed-angle mouth mirror is used, the angle and the patient's position need to be adjusted repeatedly, and it is difficult to observe the buccopalatal side of the crown of the maxillary teeth and the mesial and distal neck due to insufficient light. problems such as the inside of the pulp cavity of the upper and lower teeth, etc., to achieve a wider angle of observation
