Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to an early diagnosis detector and method for dental caries based on IPG laser fluorescence. Background Art
[0002] In the field of dentistry, dental caries is a common oral disease, and its early diagnosis is crucial for preventing the development of caries and protecting dental health. With the continuous advancement of science and technology, a variety of early caries diagnosis technologies and equipment have emerged, providing clinicians with more comprehensive and effective diagnostic tools. Existing oral observation devices play a vital role in caries diagnosis. They are typically equipped with an optical imaging system, a light source, and a data processing unit, enabling observation and imaging of the interior of the oral cavity, helping doctors detect abnormalities on the tooth surface.
[0003] However, existing oral viewers still have several limitations in practical application, restricting their effectiveness in early caries diagnosis. First, most oral viewers can only provide macroscopic images of the tooth surface, making it difficult to detect and accurately assess tiny caries lesions within the tooth. These early caries lesions may not show obvious macroscopic changes on the tooth surface, but may only manifest as minor demineralization or structural changes within the tooth. Due to the limitations of their detection methods, existing oral viewers often have difficulty capturing these subtle changes, which can easily lead to missed diagnosis of early caries. Second, the detection heads of existing oral viewers are easily contaminated during use. Oral residues such as saliva and dental plaque can adhere to the detection head surface, interfering with subsequent test results and reducing test accuracy. Furthermore, if these residues are not promptly cleaned, they can breed bacteria, increasing the risk of cross-infection and posing a threat to the patient's oral health. Furthermore, the data processing capabilities of existing oral viewers are relatively limited, typically only capable of simple image storage and display. They lack the ability to deeply analyze and process test data, making it impossible to provide doctors with comprehensive and accurate caries risk assessment information, making it difficult to meet clinical needs for personalized diagnosis and treatment planning.

[0028] After the test is complete, the micromotor reverses, driving the drive shaft counterclockwise, driving the rack downward, and retracting the test head into the storage shell. At this time, the rotation of the drive shaft drives the synchronous wheel to rotate, which in turn activates the atomizing nozzle in the disinfection assembly, spraying disinfectant onto the movable plate and the test head, disinfecting the test head and surrounding components.

[0031] 2.

DETAILED DESCRIPTION
[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0042] Please see the attached Figure 1 -Attached Figure 7The embodiment of the present invention provides an early diagnosis detector for dental caries based on IPG laser fluorescence, comprising an outer shell 1, a storage shell 5 detachably connected to the inner side of the outer shell 1, a movable plate 4 slidably connected to the inner side of the storage shell 5, a drive rack 701 fixedly connected to one side of the movable plate 4, a micro motor 702 mounted on the outer side of the storage shell 5, a transmission shaft 706 fixedly connected to the output end of the micro motor 702, a drive gear 2 705 fixedly connected to the end of the transmission shaft 706, a cleaning roller 703 movably connected to the inner side of the storage shell 5 via a bearing, a drive gear 1 704 fixedly connected to the roller shaft of the cleaning roller 703, a detection head 6 mounted on the top of the movable plate 4, a disinfection assembly mounted on the inner side of the outer shell 1, the disinfection assembly being used to disinfect the detector, and the diagnostic detector being controlled by a diagnostic system. The outer side of the drive gear 2 705 meshes with the outer side of the drive rack 701, and the outer side of the drive gear 1 704 meshes with the inner side of the drive rack 701.
[0043] Specifically, when the micromotor 702 is started, its output end drives the transmission shaft 706 to rotate clockwise. The rotation of the transmission shaft 706 further drives the drive gear 2 705 fixed at its end to rotate synchronously clockwise. Because the drive gear 2 705 is tightly engaged with the outer side of the drive rack 701, the drive rack 701 moves upward under the drive of the drive gear 2 705. As the drive rack 701 rises, its inner side engages with the outer side of the drive gear 1 704, causing the drive gear 1 704 to rotate counterclockwise. The cleaning roller 703 is fixedly connected to the roller shaft of the drive gear 1 704, so the rotation of the drive gear 1 704 drives the cleaning roller 703 to rotate counterclockwise, thereby cleaning the surface of the detection head 6. At the same time, the upward movement of the drive rack 701 drives the movable plate 4 to move upward synchronously, so that the detection head 6 mounted on the top of the movable plate 4 extends from the inside of the outer shell 1, preparing for the subsequent caries detection.
[0044] After the test is complete, micromotor 702 reverses, driving drive shaft 706 to rotate counterclockwise. This action causes drive gear 2 705 to rotate counterclockwise, which in turn drives the meshing drive rack 701 downward. The downward movement of drive rack 701 also causes movable plate 4 to move downward, allowing the test head 6 to be smoothly retracted into the storage housing 5. This automatically retracts the test head 6 and effectively protects it from damage caused by accidental collision or contact.
[0045] The disinfection assembly includes a liquid storage chamber 904 defined within the outer shell 1. A fixed cylinder 901 is fixedly mounted to the bottom of the storage housing 5. A movable rod 905 is slidably connected to the top through-hole of the fixed cylinder 901. A rubber piston is fixedly attached to the bottom end of the movable rod 905. Connecting tube 1 902 and connecting tube 2 903 are connected to the outer surface of the fixed cylinder 901, respectively. An atomizing nozzle is fixedly mounted to one end of connecting tube 2 903. Both connecting tubes 1 902 and 2 903 are internally mounted with one-way valves, each with opposite conduction directions. The rubber piston is slidably connected to the inner wall of the fixed cylinder 901.
[0046] Specifically, the liquid storage chamber 904 stores disinfectant, providing the necessary liquid for the entire disinfection process. When the movable rod 905 moves up and down, the rubber piston at its bottom slides on the inner wall of the fixed cylinder 901, changing the air pressure inside the cylinder. Connecting pipe 1 902 and connecting pipe 2 903 are respectively responsible for transporting the disinfectant from the liquid storage chamber 904 to the atomizing nozzle. The one-way valve ensures that the disinfectant can only flow in one direction to prevent backflow. Finally, the disinfectant is sprayed out through the atomizing nozzle, completing the disinfection. The entire process does not require human intervention, improving the efficiency and reliability of disinfection.
[0047] The outer side of the transmission shaft 706 is fixedly connected to a synchronous wheel 1 801, and the outer side of the synchronous wheel 1 801 is connected to a synchronous wheel 2 803 through a synchronous belt 802. The outer side of the synchronous wheel 2 803 is fixedly connected to a rotating disk 804, and a hinged rod 805 is rotatably installed at the outer eccentric part of the rotating disk 804, and one end of the hinged rod 805 is hinged to the top of the movable rod 905.
[0048] Specifically, when the drive shaft 706 rotates, it drives the first synchronous wheel 801, which, through the transmission of the synchronous belt 802, causes the second synchronous wheel 803 to rotate synchronously. The rotation of the second synchronous wheel 803 drives the rotation of the rotating disk 804. Because the hinged rod 805 is eccentrically mounted on the rotating disk 804, when the rotating disk 804 rotates, the hinged rod 805 moves in a circular motion around the center of the rotating disk 804, driving the movable rod 905 up and down. This transmission structure converts the rotational motion of the drive shaft 706 into linear motion of the movable rod 905, achieving precise control of the movable rod 905.
[0049] The bottom of the outer shell 1 is provided with a charging support 2, and the outer surface of the outer shell 1 is mounted with a control panel 3. The outer surface of the outer shell 1 is provided with a liquid infusion tube 12, one end of which is connected to the interior of the liquid storage chamber 904. The top of the movable plate 4 is fixedly connected to a cover plate 11, and a sealing gasket is mounted on the bottom of the cover plate 11. The top of the storage shell 5 is provided with a sealing groove 10 that matches the sealing gasket.
[0050] Specifically, the charging stand 2 is used to connect to an external power source to charge the built-in battery of the detector, ensuring the power supply of the device during use. The control panel 3 is installed on the outer surface of the outer shell 1 and is equipped with a display screen, operating buttons and a touch interface, etc., which are used to control the workflow of the detector, such as starting, stopping, parameter setting, etc., and display the operating status, test results and alarm information. The refill tube 12 is opened on the outer surface of the outer shell 1, and one end is connected to the interior of the liquid storage chamber 904, which is used to replenish the disinfectant in the liquid storage chamber 904 to ensure that the disinfection component can work normally.
[0051] The diagnostic system includes the following modules:
[0052] The IPG laser fluorescence detection module is equipped with a high-precision IPG laser that emits laser light of a specific wavelength to stimulate tooth tissue to produce fluorescence.
[0053] Automatic disinfection module, automatically disinfecting the detection head 6;
[0054] Oral lighting and imaging module, used to provide uniform and bright lighting inside the patient's mouth, ensuring that the inspection area is clearly visible;
[0055] The data processing and analysis module is used to process and analyze the IPG laser fluorescence signal, extract the fluorescence spectrum characteristic parameters of the teeth and compare them with the characteristic parameters of normal teeth. At the same time, it uses machine learning algorithms to build a personalized oral microbiome and caries risk assessment model;
[0056] Specifically, the data processing and analysis module is the core of the detector, responsible for processing the IPG laser fluorescence signal. It first pre-processes the signal, then extracts the characteristic parameters of the tooth fluorescence spectrum, comparing them with those of normal teeth to identify abnormalities. Simultaneously, it uses machine learning algorithms to construct an oral microbiome and caries risk assessment model, enabling personalized risk prediction and diagnostic support, improving diagnostic accuracy and early intervention effectiveness.
[0057] The data processing and analysis module includes the following units:
[0058] Signal processing unit: used to pre-process the received IPG laser fluorescence signal, including filtering, amplification, analog-to-digital conversion and other operations, to convert the original signal into a digital signal suitable for further analysis;
[0059] Feature extraction unit: extracts the fluorescence spectrum characteristic parameters of the tooth from the processed digital signal;
[0060] Data storage unit: stores fluorescence spectrum characteristic parameters of normal teeth and oral microbial community data of patients, etc.;
[0061] Comparative analysis unit: compares the extracted characteristic parameters of tooth fluorescence spectrum with those of normal teeth, identifies abnormal characteristics, and preliminarily determines the risk of dental caries;
[0062] Machine learning algorithm unit: Use machine learning algorithms to train and learn feature data to build a personalized oral microbiome and caries risk assessment model.
[0063] Specifically, the formula involved in the machine learning algorithm unit is as follows:
[0064]
[0065] Where P(y=1|X) represents the probability of a tooth having caries (i.e., the probability of belonging to the caries category) given the eigenvector X. e is a natural constant, approximately 2.71828. β0 represents the baseline probability of the model, which is the logarithmic probability of a tooth having caries when all eigenvalues are zero. β1,β2,…,β n is a characteristic coefficient vector, which corresponds to the weight of different fluorescence spectrum characteristic parameters, indicating the contribution of each feature to the occurrence of dental caries. n is a feature vector containing the characteristic parameters of the tooth fluorescence spectrum extracted from the IPG laser fluorescence signal.
[0066] The automatic disinfection module, IPG laser fluorescence detection module and oral lighting and imaging module are all connected to the data processing and analysis module.
[0067] Working principle: The specific use of this device includes the following operating principles:
[0068] The micromotor 702 is activated via the control panel 3. The output of the micromotor 702 drives the transmission shaft 706 in clockwise rotation. This clockwise rotation of the transmission shaft 706 causes the second drive gear 705 to rotate clockwise in tandem. The second drive gear 705 meshes with the outer side of the drive rack 701, driving the second drive gear 701 upward. As the drive rack 701 moves upward, its inner side meshes with the outer side of the first drive gear 704, causing the first drive gear 704 to rotate counterclockwise. This causes the cleaning roller 703 to rotate counterclockwise, cleaning the surface of the detection head 6.
[0069] As the drive rack 701 moves upward, the movable plate 4 is driven upward, and the detection head 6 extends out of the outer shell 1. After the detection head 6 is extended, the IPG laser fluorescence detection module emits laser light of a specific wavelength, which excites the tooth tissue to produce fluorescence. The fluorescence signal receiver receives the signal and transmits it to the data processing and analysis module. The data processing and analysis module preprocesses the signal, extracts features, and performs comparative analysis, and uses machine learning algorithms to construct a personalized caries risk assessment model.
[0070] After the test is complete, the output of micromotor 702 is reversed via control panel 3, driving drive shaft 706 to rotate counterclockwise. This counterclockwise rotation of drive shaft 706 synchronously rotates drive gear 2 705 counterclockwise. Driven by drive gear 2 705, drive rack 701 moves downward, driving movable plate 4 downward, allowing test head 6 to retract into storage housing 5. As movable plate 4 moves downward into storage housing 5, the sealing gasket at the bottom of cover plate 11 engages with the interior of sealing groove 10, ensuring a tight seal within storage housing 5.
[0071] As the movable plate 4 moves up and down, the rotation of the transmission shaft 706 simultaneously drives the rotation of synchronous pulley 1 801. Synchronous pulley 1 801 drives synchronous pulley 2 803 via the timing belt 802. This causes the rotating disk 804 to rotate synchronously, which in turn causes one end of the hinged rod 805 to swing. The other end of the hinged rod 805 is hinged to the top of the movable rod 905. Under the traction force of the hinged rod 805, the movable rod 905 moves up and down. Because the bottom end of the movable rod 905 is connected to a rubber piston, the up and down movement of the movable rod 905 drives the rubber piston along the inner wall of the fixed cylinder 901. This movement of the rubber piston causes the air pressure inside the fixed cylinder 901 to change, moving the disinfectant in the liquid storage chamber 904 through the connecting tube 1 902 into the connecting tube 2 903. Finally, the disinfectant is sprayed out in atomized form through the atomizing nozzle, disinfecting the detection head 6 and components near the movable plate 4. At this point, the data processing and analysis module records relevant data from the disinfection process to ensure the integrity and effectiveness of the disinfection procedure.

The drive rack (701) moves upward under the drive of the second drive gear (705), while the drive gear (704) rotates counterclockwise under the drive of the drive rack (701), driving the cleaning roller (703) to rotate counterclockwise to clean the detection head (6). As the drive rack (701) moves upward, the movable plate (4) moves upward accordingly, extending the detection head (6) out of the outer shell (1). The IPG laser fluorescence detection module emits laser light, stimulating teeth to produce fluorescence. The received signal is then transmitted to the data processing and analysis module, which processes the signal, extracts features, performs comparative analysis, and constructs a caries risk assessment model. After the detection is completed, the micro motor (702) reverses, driving the transmission shaft (706) to rotate counterclockwise, driving the rack (701) to move downward, and the detection head (6) is retracted into the storage shell (5). At this time, the rotation of the transmission shaft (706) drives the synchronous wheel (801) to rotate, and the atomizing nozzle (903) in the disinfection assembly is linked to spray the disinfectant on the movable plate (4) and the detection head (6), thereby disinfecting the detection head (6) and surrounding components.
