Description

Dental mouth mirror

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to dentistry odontoscope.

Background

When a patient is examined in the dental field, the inside of the tooth cannot be seen directly, so that the observation is needed by means of an oral mirror. At present, the mouth mirror used clinically can not provide sufficient light source, and the angle between the mouth mirror and the handle bar is fixed. When in use, doctors can suffer from the problems of dark light or unequal angles, which brings certain trouble to the doctor in the treatment process and causes inconvenience in watching. In oral examination, sometimes, the lips need to be pulled away from the labial surfaces of the anterior teeth by fingers to check the condition of the anterior teeth, which is inconvenient, easily dirties the fingers and gloves of doctors, and is not safe/sanitary for patients.

SUMMERY OF THE UTILITY MODEL

To the problems existing in the prior art, the utility model aims to provide a dental mouth mirror.

The utility model adopts the following technical proposal:

a dental mouth mirror comprises a lens, a rotary connecting seat, a connecting rod and a handle. The handle is arranged at the rear end of the connecting rod. The rotary connecting seat is rotatably arranged at the front end of the connecting rod, and the front end of the rotary connecting seat is rotatably provided with a lens seat. The lens is fixedly arranged on the lens seat. The lens is provided with a lens.

The connecting rod is slidably provided with a lip support assembly. The lip support assembly comprises a sliding seat, a first support piece, a second support piece and a retainer ring. The first support piece, the second support piece and the check ring are rotatably arranged on the sliding seat.

Furthermore, the rotary connecting seat and the connecting rod as well as the lens seat and the rotary connecting seat are in interference fit.

Furthermore, a baffle is arranged at one end of the sliding seat, and a clamping groove is formed at the other end of the sliding seat.

Furthermore, the lip support assembly further comprises an elastic snap ring. The elastic clamping ring is arranged in the clamping groove and positions the first support piece, the second support piece and the check ring.

Further, the lens mount is provided with an LED lamp, a battery and a switch, and the LED lamp is connected with the battery and the switch through wires.

Further, the first support member and the second support member are aligned at the ends.

The utility model has the advantages that: the lens can rotate at any angle through rotating the connecting seat, so that the inspection is convenient; the LED lamp may enhance illumination. When in need, the lip support component can be used for supporting the mouth angle of the patient, the visual field is expanded, a doctor can conveniently and thoroughly check the periphery of the teeth, the working efficiency is improved, and the working difficulty of medical staff is reduced.
