Novel stomatological clinical stomatoscope

Abstract

The invention belongs to the field of stomatological instruments, and particularly discloses a novel stomatological clinical stomatoscope which comprises a holding rod, a stomatoscope rod and an oralcavity distraction structure, the holding rod is columnar, antiskid lines are distributed at the outer side end face of the holding rod, and a fixing block is connected to the top end of the holding rod; the oral cavity distraction structure is arranged on the fixing block and used for assisting in distraction of an oral cavity of a patient, the oral cavity distraction structure comprises a screw,a stand column, rubber supporting rods and connecting rods, the stand column is fixedly connected to the end of the fixing block, the screw is movably connected with the end of the fixing block through a rotating shaft, and the free end, away from the fixing block, of the stand column and the free end, away from the fixing block, of the screw are connected with a supporting block; a moving blocksleeves the screw, the side end of the moving block is in guide connection with the side wall of the stand column, and the connecting rods are hinged to the moving block; the rubber supporting rods are rotationally connected to the two side ends of the fixing block, the ends, close to the screw, of the rubber supporting rods are movably connected with the free ends of the connecting rods, and distracting plates are connected to the ends, away from the connecting rods, of the rubber supporting rods. The device is better in adaptability in use, and is good in observation effect.

Description

technical field [0001] The invention relates to the field of stomatology instruments, in particular to a novel oral mirror for clinical use in the stomatology department. 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 c...
