Background

A dental odontoscope is a basic dental medical instrument and mainly comprises a handle and a fixed small round mirror at present. In the using process, the mirror surface is relatively cold, the temperature in the oral cavity of a patient is relatively high, so that the fogging phenomenon of the mirror surface is serious, and other auxiliary instruments are usually needed to be adopted to carry out operations such as flushing, blowing and the like on the mirror surface so as to keep the mirror surface clean, which is obviously very troublesome in the operation process.

Disclosure of Invention

In view of the above problems, it is an object of the present invention to provide a defogging odontoscope which can conveniently eliminate water mist on the mirror surface of the odontoscope so as to improve the working efficiency of the odontists.

Preferably, the power module comprises a battery and a periodic wave generation module, and the periodic wave generation module converts direct current output by the battery into high-frequency driving current required by the ultrasonic transducer, such as sinusoidal alternating current waves, rectangular waves or triangular waves.

Preferably, the rear end of the lens forms a lens handle which can be inserted into the handle, so that the lens can be discarded after being used once.

Preferably, the tail part of the handle is formed into a thick handle, the ultrasonic energy conversion sheet is arranged in the thick handle, the ultrasonic energy conversion sheet forms a horn with a large opening facing to the front end of the handle in the thick handle, and the horn is provided with a longitudinal section cut; the waveguide channel is communicated with the large opening of the horn barrel. Furthermore, a lighting lamp facing the front end of the handle is arranged at the small opening end of the horn cylinder, the inner circumferential surface of the horn cylinder is made into a mirror surface, the inner surface of the housing of the lens is made into a reflecting surface, the outer circumference of the lens is made into an annular light homogenizing layer, and the reflecting mirror surface of the lens is made into the annular light homogenizing layer, so that the light in the housing can penetrate through the annular light homogenizing layer to form light to the outside. Furthermore, a semiconductor refrigerating sheet is attached to the inner surface of the lens, and the lens can be quickly refrigerated when the semiconductor refrigerating sheet is electrified.

The invention has the beneficial effects that: after the defogging dental oral mirror is placed in an oral cavity, if water mist appears on the surface of the lens, the ultrasonic transduction piece in the handle is started, ultrasonic waves of the ultrasonic transduction piece are transmitted into a shell of the lens through the waveguide channel and act on the lens, the lens is vibrated at high frequency, the water mist on the surface of the lens is rapidly vaporized, and the lens is rapidly restored to a clean and bright state.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the first embodiment is as follows:

in the first embodiment shown in fig. 1, the defogging odontoscope comprises a handle 1 and a lens 2 at the front end of the handle; the lens 2 comprises a cover 21 with a cavity 210 formed therein, and a lens 22 fixed on the front surface of the cover 21; the lens 22 is composed of an elastic resin sheet plated into a reflecting mirror surface, and the ultrasonic transducer sheet 3 and the power module 4 are arranged inside the handle 1; and the inside of the handle 1 is provided with a waveguide channel 10 which can guide the ultrasonic wave generated by the ultrasonic transducer 3 into the cavity 210 of the housing 21 and act on the back surface of the lens 22. In this embodiment, a lens handle 211 is formed at the rear end of the lens 2 and can be inserted into the handle 1, so that the lens 2 can be discarded after being used once. Because the lens 22 is made of resin sheet and the housing 21 and the lens handle 211 can be integrally formed by plastic, the cost is extremely low, and the disposable scrapping does not need to be disinfected, and is convenient and quick.

The power module 4 includes a battery, which may be a dry battery or a rechargeable battery, and a periodic wave generation module, which converts the dc output from the battery into a high-frequency driving current, such as a sinusoidal ac wave, a rectangular wave, or a triangular wave, required by the ultrasonic transducer 3.

In the first embodiment, a thick handle 11 is formed at the tail of the handle 1, the ultrasonic transducer 3 is disposed in the thick handle 11, and the ultrasonic transducer 3 directly faces the connection port at the tail end of the waveguide 10.

After the defogging dental oral mirror is placed in an oral cavity, if water mist appears on the surface of the lens 22, the ultrasonic wave transducer 3 in the handle 1 is started, the ultrasonic wave of the ultrasonic wave transducer is transmitted into the housing 21 of the lens 2 through the waveguide channel 10 and acts on the lens 22, the lens 22 is vibrated at high frequency, the water mist on the surface of the lens is rapidly vaporized, and the lens 22 is rapidly restored to a clean and bright state.

Example two:

for the second embodiment shown in fig. 2-4, the functions of the first embodiment are further enhanced and expanded. First, in the second embodiment, the ultrasonic transducer piece 3 forms a horn with a large opening toward the front end of the handle 1 in the thick handle 11, and the horn has a longitudinal slit 30. The waveguide channel 10 is communicated with a large opening of the horn. The small-mouth end of the horn cylinder is provided with a lighting lamp 4 facing the front end of the handle, and the lighting lamp 4 is in a firm conical shape and seals the small mouth of the horn cylinder so as to be beneficial to reflecting the ultrasonic waves to the front. The inner peripheral surface of the horn is made into a mirror surface, the inner surface of the housing 21 of the lens 2 is made into a reflecting surface, the periphery of the lens 22 is made into an annular light homogenizing layer 222, and the reflecting mirror surface 221 of the lens 22 is made into the annular light homogenizing layer 222, so that the light in the housing 21 can penetrate through the annular light homogenizing layer 222 to form light to the outside. Therefore, the waveguide channel 10 can be fully utilized to be simultaneously used as an illumination transmission channel to provide illumination for the interior of the oral cavity, so that illumination devices such as lamp holders and the like can be prevented from entering the oral cavity to cause pollution and being damaged in the disinfection and cleaning process.

In order to further enhance the illumination effect in the second embodiment, a special optimized design is further provided in this embodiment, that is, a semiconductor chilling plate 6 is further attached to the inner surface of the lens 22, and when the semiconductor chilling plate 6 is powered on, the lens 22 can be chilled quickly. The working principle and the scene are as follows: in some cases, when it is necessary to provide a large-scale illumination to the inside of the mouth cavity, for example, when the whole mouth cavity needs to be inspected, the lens 22 is rapidly cooled, so that the liquefied mist is artificially formed on the lens 22, and then the ultrasonic transducer 3 is activated to rapidly vaporize the just-formed mist, so that a large amount of mist is formed in the mouth cavity, thereby widely scattering the illumination provided by the lens 2, so that the inside of the mouth cavity is uniformly illuminated. The problem that the illumination projected by the oral cavity by the common illuminating device is difficult to uniformly scatter after being absorbed by teeth or oral cavity walls can be solved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
