Description

a dental mirror

technical field

The utility model relates to the field of medical instruments, in particular to an oral inspection mirror.

Background technique

Oral inspection mirror, also known as mouth mirror, is a common dental instrument. The common mouth mirror is composed of a mirror body and a mirror handle; the mirror body includes a lens cover and a lens. The lens cover has a groove for placing the lens, and the lens is located in the lens cover. The groove of the lens is an interference fit. The lens is mostly round, and one end of the lens cover is fixedly connected to the handle. The connection between the lens cover and the handle is mostly two ways of integral molding and threaded connection. The mouth mirror can reflect the image of the parts that cannot be directly reached by the line of sight, such as the distal surface of the teeth, the lingual surface, and the occlusal surface of the maxillary teeth; it can also be used to reflect or gather external light to the target inspection site to increase local illumination; it can also be used to Pulling or pushing soft tissues such as the lips, cheeks, and tongue allows doctors to see the tissues covered by these soft tissues for inspection or surgery. Because the mouth mirror adopts the above-mentioned structure, the above three functions often cannot be played at the same time when it is used, because the lens is on the inside of the mouth mirror, so it also covers the lens while pulling the cheeks, which cannot play a role. The effect of anti-view image and spotlight lighting, in addition, when dentists operate dental pulp opening, root expansion, restoration, tooth extraction, and implantation, they are often blind spots. They can only be operated by experience and advance positioning. If they cannot always be in the field of vision Internal operations are prone to errors. During the oral examination by the stomatologist, the patient's oral cavity cannot be effectively opened for inspection, which brings inconvenience to the work of the doctor.

After searching, the patent document with the publication number CN00215319.X discloses a "double-sided mouth mirror". The upper end of the handle body (1) is fixed with a lens (2). ) is also fixed with another eyeglass (3) adjacent to the eyeglass (2), and the reflective surfaces of the two eyeglasses face opposite. In this patent, the mirror body of the mouth mirror is set as a double-sided mirror, so that when the dentist uses the mirror to pull and press soft tissues such as lips, cheeks, and tongue, the reflection of the tissue part covered by the soft tissue can be obtained through another mirror surface. Field of view, its structure is basically the same as that of the common double-sided mirrors in the prior art, but compared with single-sided mirrors, the frequency of use of double-sided mirrors in actual clinical practice is lower than that of single-sided mirrors. One of the reasons is that although the double-sided mouth mirror can reflect to the doctor and expose the tissue under the stretched soft tissue while it provides the stretching effect, the reflected image transmission direction is biased towards the interior of the oral cavity. It is beneficial for the doctor to observe the image of the target area. It is necessary for the doctor to tilt his head significantly to obtain the corresponding area of vision, and it is relatively limited. Take the doctor operating the double-sided mouth mirror to pull the patient's cheek to expose the root part of the tooth as an example. The inner side of the double-sided mouth mirror faces the patient's cheek, that is, one side of the double-sided mouth mirror is in direct contact with the patient's cheek, and the other side is reflected to the throat In the mouth, it is not conducive to the doctor to see the reflection field of view, but if the doctor adjusts the mouth mirror so that the imaging point of the mirror body of the mouth mirror part of the reflection field of view is more inclined to the other side of the patient's cheek to facilitate the doctor's observation, the traction effect will be reduced, because After the above adjustments, the mirror body is partly separated from the patient's cheek, leaving only the mirror handle to play a single pulling effect, and the patient will feel some discomfort at the same time.

In summary, we propose a dental inspection mirror to solve the above technical problems.
