Description

Imaging self-checking mouth mirror

Technical Field

The utility model belongs to the technical field of medical equipment's technique and specifically relates to an formation of image self-checking mouth mirror is related to.

Background

An odontoscope is a common medical instrument in the stomatology department and plays an important role in oral examination and treatment. The mouth mirror can reflect images of parts where the sight line can not directly reach, such as the far middle face of teeth, the lingual face, the facial occlusion of maxillary teeth and the like; can be used for reversing or gathering light to the examined part, increasing local illumination, and can be placed on the image by a concave mouth mirror when necessary; used for traction or pressure of the soft tissues of lips, cheeks, tongue, etc. for inspection or operation. At present traditional mouth mirror generally all needs medical personnel handheld operation, keeps handheld state can cause medical personnel's fatigue for a long time, because the warm and humid gas of oral cavity exhalation very easily generates the fog on mouth mirror surface, influences the inspection effect moreover, has brought unnecessary trouble for medical personnel's inspection and treatment.

The existing patent with the publication number of CN208355436U provides a hand-free mouth mirror for stomatology department, which comprises a fixing plate and a mouth mirror body, wherein positioning pins are arranged at four corners of the fixing plate, a fixing rod is horizontally arranged on the front surface of the fixing plate, hooks are uniformly arranged on the fixing rod, a shaped metal hose is arranged on the side edge of the fixing plate, and a connecting sleeve I is arranged on the end surface of the shaped metal hose; the mouth mirror body comprises a mouth mirror rod, a base and a lens; a lithium battery is arranged on the lower side of the base, a circular groove is arranged on the upper side of the base, and a limiting circular groove is arranged in the center of the bottom surface of the circular groove; the lens is circular and arranged in the circular groove, and comprises a convex mirror, a heat transfer layer and a heating layer; the bottom surface both ends of zone of heating are equipped with conducting block group I, and the upside society of circular recess is equipped with conducting block group II. The utility model can fix the mouth mirror, and avoid fatigue and stiffness caused by holding the mouth mirror for a long time by medical care personnel; the convex mirror surface can be heated, and the fogging of the mirror surface is prevented.

The above prior art solutions have the following drawbacks: in the prior art, the mouth mirror body is fixedly connected with the handle rod. When a doctor stretches the mouth mirror body into the oral cavity of a patient, when the oral diameter body is located at a deep position in the oral cavity, light rays can hardly shine on the dark position in the oral cavity, and the doctor usually needs to hold a lighting tool such as a flashlight for local lighting. It is difficult to clearly see the teeth at each of the deeper locations within the mouth. Therefore, there is room for improvement.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing an image formation self-checking mouth mirror, when observing patient's tooth condition with the mouth mirror, do not need the handheld lighting fixture of doctor, can see clearly that the patient is located the tooth of each deeper position department in oral cavity inside.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides an formation of image self-checking odontoscope, includes the odontoscope body, the odontoscope body is including holding pole, base and odontoscope, base fixed connection in the one end of holding the pole, odontoscope fixed connection in the up end of base, logical groove has been seted up in the base, it is connected with the movable plate to lead to the vertical sliding of inslot, the movable plate is close to a plurality of LED lamps of one side fixedly connected with of odontoscope, a plurality of confessions have been seted up to the base up end the through-hole that the LED lamp passed, it is used for ordering about to lead to the inslot the vertical drive assembly who slides of movable plate, be equipped with on the holding pole and be used.

Through adopting above-mentioned technical scheme, when stretching into the inside darker position department in patient's oral cavity with the mouth mirror, open the switch of LED lamp, according to the actual need of light luminance, drive assembly makes the movable plate along vertical direction displacement to adjustment LED lamp is apart from the position of through-hole, and LED lamp is close more apart from the through-hole, and the light luminance that it distributed out is stronger more, and the region of its illumination is bigger. Therefore, the utility model discloses when observing the patient's tooth condition with the mouth mirror, do not need the handheld lighting fixture of doctor, can see clearly the tooth that the patient is located inside each deeper position department in oral cavity.

The present invention may be further configured in a preferred embodiment as: the driving assembly comprises a first gear and a first rack, the first rack is vertically and fixedly connected to the moving plate far away from the side wall of the mouth mirror, the first gear is meshed with the first rack, a rotating shaft is connected to the base in a rotating mode, the first gear is coaxially and fixedly connected to the end, close to the first rack, of the rotating shaft, the end, far away from the first rack, penetrates out of the base, and the rotating shaft is arranged along the length direction of the holding rod.

Through adopting above-mentioned technical scheme, thereby rotatory axis of rotation, gear one is rotatory to drive rack one and follows vertical direction displacement in leading to the inslot, and when rack one upwards slided along vertical direction, a plurality of LED lamps are close to the through-hole gradually to finally stretch out to the height that keeps the parallel and level with the through-hole, thereby the tooth of the inside darker position department of patient's oral cavity is lighted to illumination brightness that can be the biggest. When required light luminance is less, rotatory axis of rotation, thereby the rotatory rack that drives of gear slides downwards along vertical direction in leading to the inslot, and the through-hole is kept away from gradually to a plurality of LED lamps to the light luminance that makes to shine patient oral cavity inside reduces.

The present invention may be further configured in a preferred embodiment as: the rotating shaft penetrates through the second gear which is fixedly connected with one end of the base in a coaxial mode, the holding rod is fixedly connected with a fixed plate, the holding rod is provided with a second rack which is used for being connected with the second gear in a meshed mode, the second rack penetrates through the fixed plate, the second rack is far away from a blocking plate which is fixedly connected with one end of the second gear, the blocking plate is used for limiting the second rack to be separated from the fixed plate, and the holding rod is provided with a restoring piece which drives the second rack to return to an initial position.

By adopting the technical scheme, the second gear is pressed, and the second gear rotates to indirectly drive the first gear to vertically move downwards, so that the moving plate slides downwards along the vertical direction. And (3) loosening the second rack, returning the second rack to the initial position under the action of the restoring piece, and in the process, rotating the second gear to indirectly drive the first rack to vertically and upwardly displace so as to enable the moving plate to slide along the vertical direction. Compared with the mode of directly rotating the rotating shaft by adopting the mode of pressing to rotate the rotating shaft, the mode of rotating the rotating shaft is more convenient for doctors to operate.

The present invention may be further configured in a preferred embodiment as: the restoring piece is a compression spring, and two ends of the compression spring are fixedly connected to the blocking plate and the fixing plate respectively.
