Oral medicine teaching mirror image training device and training method thereof

Abstract

The invention relates to the technical field of medical teaching equipment. The invention further discloses an oral medicine teaching mirror image training device. The device comprises a mirror box; rear cover inserting seats are fixedly connected to the top and the bottom of the right side of the mirror box; a rear cover inserting groove is formed in the surface of the right side of each rear cover inserting seat; and bearing mounting grooves are formed in the top and the bottom of the right side surface of a mounting base. A rotating handle is screwed to drive a screw rod to rotate so as topush the mounting base to move outwards, the mounting base drives a left connecting strip to pull a spring to slowly extend to control the displacement amplitude of the mounting base, the inner wall of the inner ring of the bearing is fixedly connected with the tail end of the screw rod through the horizontal line of the screw rod penetrating hole and the screw rod inserting hole, the angle of thescrew rod is ensured not to deviate when the screw rod rotates and displaces, so that the angle of a frontal mirror can be freely adjusted from the upper side or the lower side, and dead angles whichare not easy to observe can be observed more conveniently.

Description

technical field [0001] The invention relates to the technical field of medical teaching equipment, in particular to a mirror image training device for stomatology teaching and a training method thereof. Background technique [0002] The mirror image training device for oral medicine teaching is a concave reflective mirror device that can be used for wearing on the head. It is an auxiliary inspection device commonly used in the ENT department. concave mirror , the focal length is about 25cm, and there is a small hole in the center. The mirror body is connected to the strap by other devices. The light source can be reflected to the inspected part through the concave surface. The small hole in the center of the mirror is used for peeping by the examiner's eyes. [0003] The angle of the existing mirror image training devices for oral medicine teaching cannot be adjusted during use. Even if some merchants manufacture products that can adjust the angle, they can only adjust the d...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mirror image training device for oral medicine teaching and its training method, which can freely adjust the angle of the frontal mirror from above or below, so that it is more convenient to observe some difficult-to-observe The advantage of the dead angle solves the problem that the angle of the existing dental teaching mirror training device cannot be adjusted during use. Even if some merchants manufacture products that can adjust the angle, they can only adjust the mirror distance, but cannot adjust the observation angle of the frontal mirror. The problem
