Description

Technical Field

[0001] The invention relates to the technical field of laser mobile phone state evaluation, and more specifically to a dental laser mobile phone state evaluation method. Background Art

[0002] As a new technology in the dental field, laser has been closely watched. The optical fiber of the laser is flexible and thin, and can freely enter the bottom of the periodontal pocket and any area in the oral cavity. The laser with a wavelength of 1064nm has the characteristics of moderate penetration depth into human tissue and moderate heat generation. The use of low-energy laser can effectively seal the capillaries in the oral cavity, and can also decompose and denature bacterial proteins to achieve the effects of swelling, hemostasis and sterilization. Acting on dentin, it can kill some nerve cells and achieve the effect of desensitization. At the same time, it can also be used to remove caries and necrotic tissue and dirt in the root canal for filling. Its energy can be freely adjusted within the threshold range, has good biological characteristics, has unique advantages in the treatment of oral diseases, and is currently a new means of treating oral diseases.

[0003] Currently, in the process of oral treatment, for tooth treatment, low-energy lasers can be used to achieve the therapeutic effect of closing the capillaries in the oral cavity and removing necrotic tissue and dirt in caries cavities and root canals. The laser is mainly emitted by a laser generator, which is arranged inside a laser mobile phone. After long-term use of a laser mobile phone for treatment, in order to ensure the safety and stability of the equipment, it is usually necessary to evaluate its status. Currently, most traditional evaluation methods are to check the appearance of the laser mobile phone. As the laser generator of the laser mobile phone, it is not convenient to evaluate the stability and safety during its long-term operation, which affects the treatment effect and stability of the laser mobile phone. In view of this, we propose a method for evaluating the status of a dental laser mobile phone. Summary of the invention

[0004] The purpose of the present invention is to provide a method for evaluating the status of a dental laser handpiece, so as to solve the technical problem that most traditional evaluation methods are to check the appearance of the laser handpiece, and the laser generator as the laser generator of the laser handpiece is not convenient for evaluating the stability and safety during its long-term operation.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for evaluating the state of a dental laser handpiece, comprising the following steps:

[0006] S1. Sealing evaluation;

[0007] Use professional sealing testing equipment to perform pressure tests on the phone casing to ensure that there is no gas or liquid leakage within a specific pressure range, check the corrosion resistance and antibacterial properties of the casing material, ensure that there is no liquid penetration and dust entry during use and disinfection, and that it can effectively resist the erosion of common disinfection agents;

[0008] S2. Cross-infection risk assessment;

[0009] Use a combination of 3D modeling analysis and actual simulation operations to evaluate the structural design of mobile phones and determine whether there are dead corners that are difficult to clean and disinfect. For possible dead corners, further analyze their causes and potential risks, and put forward improvement suggestions;

[0010] Collect samples before and after disinfection, use microbial culture and detection technology to verify the effectiveness of mobile phone disinfection methods, and conduct multiple batches of tests on high-temperature and high-pressure disinfection and chemical disinfection to ensure that all kinds of pathogenic microorganisms, including bacteria, viruses, fungi, etc., can be killed. At the same time, evaluate the impact of the disinfection process on mobile phone components to ensure that the performance and life of the mobile phone are not damaged after disinfection;

[0011] S3, laser energy control evaluation;

[0012] Use high-precision laser energy measuring instruments to test the energy output accuracy of laser mobile phones multiple times under different working modes and power settings, compare the measurement results with the set values, calculate the error range, and ensure that the energy output is within an acceptable error range. For the laser output under a specific power setting, measure it multiple times continuously, take the average value and compare it with the set value. The error should be controlled within 0.01;

[0013] Continuously monitor the stability of laser energy output, record energy fluctuations within a certain period of time, analyze its stability indicators, record energy output values ​​every 5 minutes within half an hour, calculate indicators such as the standard deviation of energy fluctuations to evaluate stability, and determine its energy parameter range under different treatment needs, such as the optimal energy range required for different treatment scenarios such as soft tissue cutting and hard tissue ablation. Through actual testing on different oral tissues, combined with clinical experience, determine the appropriate energy range for each scenario;

[0014] Through a combination of theoretical calculation and actual testing, theoretical calculations are performed based on parameters such as the thermal damage threshold of oral tissue and laser penetration depth, and then verified by actual animal experiments or simulation experiments to determine the upper limit and safety threshold of laser energy, taking into account factors such as the tolerance of the patient's oral tissue and the safe distance from surrounding important organs, to provide a safety margin for treatment;

[0015] Establish a real-time monitoring system to dynamically monitor the laser energy during use. Once it exceeds the safety range, an alarm will be immediately issued and the laser output will be automatically stopped. The monitoring system collects laser energy data in real time through sensors and compares it with the preset safety range to trigger the corresponding alarm and control mechanism;

[0016] S4, performance stability evaluation;

[0017] Use the long-term continuous working test method to monitor the performance of the mobile phone during long-term use, record the changes in key parameters such as energy output, frequency, wavelength, check whether there are problems such as energy attenuation and frequency fluctuation, and analyze the reasons for performance degradation and propose corresponding solutions;

[0018] Conduct durability tests on laser generators to simulate stress conditions in actual use, such as vibration, impact, temperature changes, etc., and evaluate the life and reliability of laser generators through multiple cycle tests;

[0019] For temperature changes, the specific implementation is as follows:

[0020] Set different temperature ranges, including low temperature, normal temperature, and high temperature environments, and place the dental laser handpiece in these environments for a specific length of time for testing. In each temperature range, continuously monitor the performance parameters of the laser generator, the output stability of the laser emission core component, and the transmittance change of the optical lens. Analyze the impact of temperature changes on the performance of the laser generator material, such as the impact of the thermal expansion coefficient on the dimensional accuracy of the component, and the impact of temperature on the conductivity of electronic components. Through multiple rounds of testing, establish a relationship model between temperature and laser generator performance changes, and predict the life attenuation of the laser generator under different temperature conditions. At the same time, evaluate the effectiveness of the mobile phone's heat dissipation system under different temperature environments, check whether the heat dissipation channel is unobstructed, and whether the performance of the heat dissipation material is stable;

[0021] The energy output stability index is measured by the standard deviation of energy output within a certain period of time. The smaller the standard deviation, the higher the stability. The frequency stability can be determined by comparing the deviation between the frequency measurement value and the set value in different time periods. The wavelength stability is monitored by a spectrum analyzer to ensure that the wavelength fluctuates within the allowable error range. The life assessment of the laser generator is determined by simulating the actual number and time of use and observing the time and number of times the component performance drops to a certain level. Reliability can be measured by statistically analyzing the probability of failure within a certain test cycle.

[0022] Preferably, the cross-infection risk assessment also includes an assessment of protective measures for connection points between the mobile phone and external devices, specifically by combining sealing detection and microbial detection to check the sealing and antibacterial properties of the connection points to ensure that no contaminants enter the interior of the mobile phone through the connection points.

[0023] Preferably, the laser energy control evaluation also includes stability detection of parameters such as frequency and wavelength of laser emission, and uses professional equipment such as a spectrometer to monitor the frequency and wavelength of the laser in real time under different working conditions, analyze its stability index, and compare it with the set value to ensure that the laser parameters fluctuate within a reasonable range.

[0024] Preferably, the performance stability evaluation also includes adaptability testing of the mobile phone under different environmental conditions, simulating different environmental conditions such as temperature, humidity, air pressure, etc., testing the performance of the mobile phone under these conditions, and evaluating its stability and reliability in various actual usage environments.

[0025] Preferably, in S2, when conducting a cross-infection risk assessment, the verification of the effectiveness of the disinfection method covers mobile phone samples from different batches to ensure the reliability of the assessment results.

[0026] Preferably, in said S3, in the laser energy control evaluation, the differences in oral tissue characteristics of different patients should be considered when determining the energy parameter range to achieve personalized treatment.

[0027] Preferably, in S4, in the performance stability evaluation, the durability test of the laser generator should include situations at different usage frequencies to better simulate the actual usage scenario.
