Detailed description of the preferred embodiment
As shown in fig. 1 and 3, the main configuration block diagram of the oral examination apparatus of the present invention is shown. The preferred embodiment discloses an oral cavity examination device 100 for detecting a tooth area or an alveolar bone area covered by gingival tissue to support a user to find a periodontal disease-causing factor in a detected area (an area under actual detection), which includes a laser generator 10, a power switching unit 11, a white light source generator 12, an image sensor 20, a data processing unit 30, a power input 40, a data exchange module 50, and a storage unit 60.

the laser generator 10 emits laser light which is one of visible light, infrared light and ultraviolet light, and the laser generator 10 is used for emitting laser light to irradiate the detected area, so as to excite a fluorescence spectrum S102;
because the penetration force of the laser with different wavelengths and different powers to the gingival tissues of the human body is different, on the premise of not affecting the health of the human body (the purpose of the invention), the power switching unit 11 is used for changing the power of the laser emitted by the laser generator 10, so that the detected area is excited to generate a plurality of fluorescence spectrums S102 under the irradiation of the laser with different powers, and a fluorescence spectrum information base is obtained. Wherein at least one of the different powers of the laser generator 10 can penetrate the gingival tissue of the user so that at least one of the lasers can irradiate the tooth or alveolar bone covered by the gingival tissue and emit a fluorescence spectrum.
As shown in fig. 2, the data exchange module 50 is configured to transmit the obtained fluorescence spectrum information base to the external terminal device 120 or the external cloud server 110 for displaying or analyzing. Wherein, the displaying means that when the user (user or doctor) knows the fluorescence spectrum excited by the normal teeth under the laser irradiation, the existence information of the pathogenic factor of the periodontal disease in the detected region can be displayed through the displaying function of the external terminal device 120 or the external cloud server 110; the analysis means that when the external terminal device 120 or the external cloud server 110 stores the fluorescence spectrum excited by the normal tooth under the laser irradiation, the existence information of the periodontal disease pathogenic factor in the detected region can be directly output through the comparison analysis of the external terminal device 120 or the external cloud server 110.
In this embodiment, the power switching unit 11 changes the power of the laser generator 10 to emit laser light by changing the current passing through the laser generator 10 (in a manner of a common control circuit). In other embodiments, the power switching unit 11 may change the power of the laser generator 10 to emit laser light by changing the frequency of the laser generator 10 to emit laser light.
As shown in fig. 1, the inspection apparatus 100 further includes an image sensor 20. In the present embodiment, the data exchange module 50 includes a wireless transmitting and receiving unit 52 and a data output port 51 for connecting data lines. Of course, in other embodiments, only one of the wireless transceiver unit 52 and the data output port 51 may be provided. As shown in fig. 3, the laser generator 10 emits laser light S101 and irradiates the detected region to excite a fluorescence spectrum S102, and the image sensor 20 records a plurality of fluorescence spectra S102 (fluorescence spectrum information base) to obtain a plurality of fluorescence images S103 and form a fluorescence image base; the data exchange module 50 transmits the fluorescence image library to the external device S104 for display or analysis, wherein the external device S104 is an external terminal device 120 or an external cloud server 110. The data exchange module 50 transmits the fluorescence spectrum information base to the external terminal device 120 or the external cloud server 110 by: the inspection apparatus 100 converts the fluorescence image S103 into an electrical signal and transmits the electrical signal to the external terminal device 120 or the external cloud server 110 through the data exchange module 50. In this embodiment, the mode of the image sensor 20 recording the fluorescence spectrum information library to obtain the fluorescence image library is a photographing mode. In other embodiments, the way in which the image sensor 20 records the fluorescence spectrum information library to obtain the fluorescence image library can also be in the form of camera shooting.
In this embodiment, the laser generator 10 and the image sensor 20 are disposed on the same component, the number of the image sensors 20 is one, the laser generator 10 and the image sensor 20 operate synchronously, and the connection mode between the laser generator 10 and the image sensor 20 is a wired connection mode. The execution mode of the synchronous operation may be a manual control mode, a voice control mode or a program control mode. Laser generator 10 emits one of seven visible lights, for example: laser generator 10 emits one of blue, red, or violet light. The wavelength ranges of the seven visible lights can refer to the range values disclosed in the relevant tool books.
As shown in fig. 1, in this embodiment, the inspection apparatus 100 further includes a white light source generator 12, the white light source generator 12 is configured to emit white light to illuminate the detected area in a state that the laser generator 10 does not emit laser light, so that the image sensor 20 records image information i of the detected area under the white light illumination, and the image information i is transmitted to the external terminal device 120 or the external cloud server 110 through the data exchange module 50 for displaying or analyzing. In this embodiment, the image sensor 20 records the image information i under white light irradiation in a form of photographing. In other embodiments, the image sensor 20 may record the image information i under white light irradiation in the form of image pickup.
In the present embodiment, the storage unit 60 is used to store various information in the inspection apparatus 100, such as a fluorescence spectrum information library, a fluorescence image library recorded by the image sensor 20, and image information i under white light irradiation. In this embodiment, the storage unit 60 further stores a grade table of laser power data emitted by the laser generator 10 and a thickness data table of the data in the grade table, wherein the thickness data table indicates a thickness of the laser light emitted by the laser generator 10S 101 to penetrate through the gingival tissue, and the power switching unit 11 switches the power of the laser generator 10 to emit the laser light according to the data in the grade table. The power switching unit 11 switches the power of the laser generator 10 to emit laser light according to the data in the grade table, and specifically, the power switching unit 11 controls the laser generator 10 to operate in the power sequence from small to large. When the power of the laser emitted by the laser generator 10 is changed, when the fluorescence spectrum excited by the laser S101 irradiating the detected region is changed before and after, the thickness data in the thickness data table corresponding to the power data of the laser emitted by the laser generator 10 when the fluorescence spectrum is changed for the first time is searched, so that the thickness information of the gum tissue of the user in the detected region can be obtained. When the power switching unit 11 switches the power of the laser emitted by the laser generator 10, the fluorescence spectrum excited by the laser S101 on the tooth surface, the alveolar bone surface, or the periodontal disease-causing factor is different from the fluorescence spectrum excited in the gingival tissue, and the fluorescence spectrum excited by the laser with different power in the same tissue (such as the tooth surface, the alveolar bone surface, the periodontal disease-causing factor, and the gingival tissue) only changes in brightness, and the shape of the fluorescence spectrum is the same or similar and does not change fundamentally; it is possible to detect the thickness information of the gum tissue as described above.

The thickness data in the thickness data table is calculated, for example: when the fluorescence spectrum reflected by the tooth surface or the alveolar bone surface is recorded, the thickness information of the gingival tissue can be obtained by dividing the calculated thickness by 2; when the fluorescence spectrum is obtained through the gap between the teeth through the gingival tissue, the thickness obtained by dividing the thickness by 2 can also approximately obtain the thickness information of the gingival tissue.
In this embodiment, the power switching unit 11 switches the power of the laser emitted by the laser generator 10 according to the data in the grade table in such a manner that, when the power switching unit 11 runs once according to the power data in the grade table, the power switching unit 11 considers that the detection in the detected area is completed, and starts to enter the detection in the next detected area; in other embodiments, it may be that when the obtained fluorescence spectrum changes before and after, the power switching unit 11 considers that the detection in this detected region is completed, and starts the detection in the next detected region.
