Description

Visual tooth cleaner

Technical Field

The invention relates to an oral cleaning tool, in particular to a visual tooth cleaner for cleaning teeth and interdentium.

Background

When teeth are not clean for a long time or people smoke, drink tea and drink wine for a long time, the problems of calculus, dental plaque, pigmentation and other teeth are easily caused on the surfaces of the teeth. At present, the conventional way for removing dental problems such as dental calculus, dental plaque, pigmentation and the like is to wash teeth in professional oral hospitals.

At present, the common mode for removing dental calculus, dental plaque and pigment deposition in the process of tooth washing is to extend a working head of a tooth cleaner which rotates or vibrates at a high speed, such as an ultrasonic tooth cleaner, into the oral cavity, loosen the dental plaque and break up dirt on the surface of teeth under the friction or vibration action of the working head, so that the aim of cleaning the dental calculus, the dental plaque and the pigment deposition is achieved.

Since the working head needs to be extended into the oral cavity, and the light inside the oral cavity is very dark, it is very difficult to see the situation inside the oral cavity, so the prior art is usually performed by dentists in dental clinics, and dental calculus, dental plaque, pigmentation, tongue fur and the like in the oral cavity of a patient are cleaned by means of a dental treatment workbench or a dental treatment chair by means of professional instruments.

During cleaning, a doctor usually illuminates the oral cavity by an external light source, but during operation, the doctor needs to lower the head to observe the inside of the oral cavity, so that the light source is very easy to block for illumination. Particularly, when the outer side of the molar in the deep oral cavity is cleaned, the working part is in the deep oral cavity and is shielded by cheek muscles, so that the doctor is very difficult to observe in the operation process, the head posture is often required to be adjusted or the waist is required to be bent to adapt to the visual field observation in tooth cleaning, and diseases such as cervical spondylosis and lumbar vertebra are very easily caused by the long-term head lowering work of the doctor.

In order to overcome the disadvantages of the prior art, it is necessary to develop a visual dental scaler which can directly display the internal state of the oral cavity on a display, and can visually perform fixed-point cleaning, polishing and polishing on the teeth, so that a dentist can maintain a relatively comfortable posture to perform medical tasks such as tooth cleaning, reduce fatigue, and prevent diseases such as cervical spondylosis and lumbar vertebra.

The camera system 24 is disposed within the housing 31 of the handle 300. The camera system 24 is installed in the housing 31, so that the working portion 400 can be easily replaced while ensuring observation. Meanwhile, as the lens is sealed in the shell 31, waterproof treatment can be better carried out, and the surface of the lens 24-1 cannot be observed clearly due to the shielding of liquid in the cleaning process.

The camera 24-1 of the camera system 24 protrudes from the housing 31 through the connecting structure 25. The camera 24-1 can extend out of the shell 31, and the position and the angle of the lens 24-1 can be adjusted according to needs in the cleaning process, so that the use process is more convenient.

The surface of the camera 24-1 of the camera system 24 is of a waterproof design. The surface of the camera 24-1 can be subjected to antifogging coating treatment, and after the antifogging coating treatment, even if a small amount of water vapor is formed at the front end of the camera 24-1 and condensed on the surface of the camera 24-1, the water vapor does not exist in a water drop shape, but is converted into a transparent water film, so that a fog phenomenon cannot be formed in front of the camera 24-1, and the observation effect in clinical use is clearer and more stable.

Further, the surface of the camera 24-1 of the camera system 24 is provided with a hydrophobic coating. The hydrophobic coating can make the water drop slide off after the water drop is quickly condensed on the surface of the lens 24-1 and can not stay on the surface of the lens 24-1, so that the surface of the lens 24-1 is kept clear.
