Abstract

The improved dental mirror consists of one circular reflector and one handle. There are one motor and one battery compartment inside the handle, one pedestal in the front end of the handle, one cavity with one tray inside the pedestal, and one transmission gear mechanism set below the tray and connected via a driving shaft to the output shaft of the motor. The reflector is set on the tray, and the transmission gear mechanism is provided with speed varying mechanism. The motor drives the reflector to rotate via the transmission mechanism and the rotating reflector generates centrifugal force to eliminate water fog, liquid and dust from the surface to maintain the clean mirror.

Description

Technical field:

[0001] The present invention relates to medical instruments, in particular to a medical auxiliary observation device, in particular to a dental reflector, in particular to an improved dental oral mirror. Background technique:

[0002] In the prior art, a dentist oral mirror is composed of a reflector and a handle, the reflector is arranged at the front end of the handle, and the mirror surface of the reflector forms an angle between 110° and 160° with the handle. When in use, the reflector extends into the patient's mouth, and the dentist adjusts the angle of the reflector to reflect the lighting on the treatment chair to the teeth that need to be inspected and treated, and then observe. Due to the high humidity of the air in the oral cavity, the temperature is usually higher than the room temperature, and the mirror surface temperature is usually equal to room temperature, so the water vapor in the oral cavity is easy to condense on the mirror surface of th...
