Special oral mirror for medical treatment of stomatology department

Abstract

The invention discloses a special oral mirror for medical treatment of a stomatology department. The oral mirror comprises a fixing cylinder, a screw is installed inside the fixing cylinder, a drivengear is installed in the middle of the right end of the screw, a driving gear is meshed with the lower end of the driven gear, a driving shaft is installed in the middle of the lower end of the driving gear, a moving column is mounted on the left end of the screw, a guiding sleeve sleeves the outer side of the moving column, a buffer spring sleeves the outer side of the screw between the right endof the guiding sleeve and the moving column, a fixing ball is connected to the left end of the moving column, grooves are uniformly formed in the inner side of the fixing ball, a rotating ball is installed inside the fixing ball, and the middle of the left end of the rotating ball is connected with a rotating rod. According to the oral mirror, through the mutual cooperation between the moving column and the screw, the change of the telescopic length of the oral mirror is achieved; through the mutual cooperation between the fixing ball and the rotating ball, the adjustment of the rotation angle of the oral mirror is achieved, the operation is simple, the reliability is high, the needs of medical workers for observing internal pathological tissues of patient mouths are satisfied, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special mouth mirror for stomatology. Background technique [0002] The mouth is the beginning of the digestive tract. The front fissure communicates with the outside world, and the back passes through the pharynx to continue with the pharynx. There are teeth, tongue and other organs in the oral cavity. The front wall of the oral cavity is the lips, the side wall is the cheeks, the roof is the palate, and the floor of the mouth is the mucosa and muscles. The oral cavity is divided into the anterolateral oral vestibule and the posteromedial oral cavity by the upper and lower dental arches; when the upper and lower teeth occlude, the oral vestibule and the oral cavity proper can be communicated through the gap behind the third molars. Clinically, when the patient's teeth are tightly closed, the mouth gag or cannula can be placed through this channel to inject drugs or ...

Problems solved by technology

[0003] Nowadays, the medical mouth mirrors used in stomatology are simple in structure and single in function. Since the length of the existing medical mouth mirrors is fixed, we need to move back and forth constantly to move more light into the interior for our observation. , which increases our difficulty invisibly. At the same time, the existing medical mouth mirror requires us to continuously rotate the whole mouth mirror to shine the reflected light into the mouth, which also increases the difficulty of observing the lesion. Therefore, we Introduced a special mouth mirror for stomatology
