Description

Technical Field

[0001] The invention relates to the technical field of laser irradiation therapy, in particular to a novel optical system for a laser irradiation therapy apparatus. Background Art

[0002] When in use, the medical laser device needs to continuously irradiate the patient's area. Since the laser irradiation will form a higher temperature at the irradiation site, the patient's area can be treated. However, as the laser irradiation continues, the laser will penetrate the patient's area and irradiate the normal tissue structure. In order to avoid laser damage to the normal tissue structure, the laser emitting device needs to be turned off to stop laser irradiation.

[0003] The Chinese invention patent application with publication number CN116173423A discloses a laser therapy device, a laser control method and a medium, comprising the following steps: detecting the temperature value of the laser irradiation area on the laser action object; when the temperature value is greater than a set threshold, the driving device controls the movable part to block the laser irradiation of the action object. Its beneficial effect is: the action object is treated by the laser emitting device, and after receiving the end of treatment instruction, the temperature of the laser irradiation area is measured by the temperature measuring device to determine whether the laser emitting device is turned off. When the temperature of the laser irradiation area is greater than the set threshold, it can be known that the laser emitting device is not turned off. At this time, the driving device controls the movable part to move to block the laser, so as to prevent the laser from continuing to act on the action object and causing continuous damage.

[0004] Existing laser irradiation therapy devices have the problem of being inconvenient to conduct comprehensive monitoring and inspection of each key part, resulting in the system being unable to detect and issue warnings in a timely manner when deviations occur, thereby ensuring the accuracy of laser irradiation. Summary of the invention

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a new optical system for laser irradiation therapy apparatus, comprising a component position detection module, a usage condition evaluation module, a laser inspection module and a laser transmission process inspection module, wherein: the component position detection module is used to inspect the position of each component of the optical generating unit in the laser irradiation therapy apparatus, and judge whether the optical generating unit of the laser irradiation therapy apparatus is normal, and if not, issue an early warning prompt; the usage condition evaluation module is used to judge whether the usage conditions of the laser irradiation therapy apparatus are qualified when the optical generating unit is normal, and if not, issue an early warning prompt; the laser inspection module is used to judge whether the operating state of the laser is normal when the usage conditions are qualified, and if not, issue an early warning prompt; the laser transmission process inspection module is used to judge the state of the laser generated by the laser in the transmission process when the operating state of the laser is normal, and judge whether the uniformity in the laser transmission process is qualified, and if qualified, the laser continues to generate laser, and if unqualified, the laser stops generating laser and issues an early warning prompt.

[0007] Furthermore, the method of judging whether the optical generating unit of the laser irradiation therapy device is normal includes the following steps: obtaining actual position data of each component of the optical generating unit in the laser irradiation therapy device; comparing and analyzing the actual position data with reference data of each component of the optical generating unit stored in a database to obtain a position determination parameter; comparing the position determination parameter with the position parameter stored in the database: if the position determination parameter is greater than the position parameter stored in the database, the optical generating unit of the laser irradiation therapy device is abnormal; if the position determination parameter is not greater than the position parameter stored in the database, the optical generating unit of the laser irradiation therapy device is normal.

[0008] Furthermore, the calculation formula of the position determination parameter is as follows:

[0011] Furthermore, the determination of whether the conditions for use of the laser irradiation therapy device are qualified includes the following steps: obtaining the use condition data of the therapy device, the use condition data of the therapy device including the external temperature of the therapy device during use, the standard deviation of the laser input current during use, and the length of time the laser has been in use; determining whether the length of time the laser has been in use exceeds the limited use time set in the database: if the length of time the laser has been in use exceeds the limited use time set in the database, the use condition of the laser irradiation therapy device is unqualified; if the length of time the laser has been in use does not exceed the limited use time set in the database, obtaining the internal and external environment evaluation values ​​of the therapy device based on the external temperature of the therapy device during use and the standard deviation of the laser input current during use; if the internal and external environment evaluation values ​​of the therapy device are greater than the internal and external environment evaluation threshold value of the therapy device set in the database, the use condition of the laser irradiation therapy device is unqualified; if the internal and external environment evaluation values ​​of the therapy device are not greater than the internal and external environment evaluation threshold value of the therapy device set in the database, the use condition of the laser irradiation therapy device is qualified.

The calculation formula of the internal and external environment evaluation value of the therapeutic device is as follows:

[0013]

[0014] Where Zp is the evaluation value of the internal and external environment of the therapeutic device, Ws is the external temperature of the therapeutic device when in use, Ds is the standard deviation of the laser input current when in use, Wc is the external parameter temperature of the therapeutic device, and Dc is the parameter standard deviation of the laser input current.

[0015] Further, the determination of whether the operating state of the laser is normal includes the following steps: obtaining the allowable operating deviation data of the laser, the allowable operating deviation data including the allowable operating temperature deviation value, the allowable output power deviation value, the allowable operating power consumption deviation value and the allowable operating pulse width deviation value; obtaining the actual operating data of the laser when the optical generating unit generates laser, the actual operating data including the actual operating temperature, the actual output power, the actual operating power consumption and the actual operating pulse width; obtaining the reference operating data of the laser when the optical generating unit generates laser stored in the database, the reference operating data including the reference operating temperature, the reference output power, the reference operating power consumption and the reference operating pulse width; comprehensively analyzing the allowable operating deviation data, the actual operating data and the reference operating data to obtain the laser operating state evaluation value; comparing the laser operating state evaluation value with the laser operating state evaluation threshold stored in the database: if the laser operating state evaluation value is greater than the laser operating state evaluation threshold stored in the database, the laser operating state is normal; if the laser operating state evaluation value is not greater than the laser operating state evaluation threshold stored in the database, the laser operating state is abnormal.

[0016] Furthermore, the obtaining of the allowable operation deviation data of the laser comprises the following steps: when the laser has been in use for no longer than the limited use time set in the database, comparing the therapeutic device use condition data with the therapeutic device use condition matching data stored in the database to obtain an operation deviation data matching index, wherein the therapeutic device use condition matching data comprises the external matching temperature of the therapeutic device during use, the matching standard deviation of the laser input current during use and the matching time the laser has been in use; obtaining the therapeutic device use condition matching data corresponding to the minimum operation deviation data matching index and the corresponding allowable operation deviation data of the laser stored in the database.

[0020] Furthermore, the determination of whether the uniformity during laser transmission is qualified includes the following steps: matching the laser reference uniformity when each component in the optical generating unit receives the laser and the laser reference uniformity irradiated on the skin from the database based on the actual operating temperature and the actual output power; obtaining the laser actual uniformity when each component in the optical generating unit receives the laser and the laser actual uniformity irradiated on the skin; comparing each laser reference uniformity with the corresponding laser actual uniformity, if the deviation between any laser reference uniformity and the corresponding laser actual uniformity is greater than the deviation threshold set in the database, the uniformity during laser transmission is unqualified; if the deviation between any laser reference uniformity and the corresponding laser actual uniformity is not greater than the deviation threshold set in the database, obtaining a deviation comprehensive value based on each deviation; if the deviation comprehensive value is greater than the deviation comprehensive threshold set in the database, the uniformity during laser transmission is unqualified; if the deviation comprehensive value is not greater than the deviation comprehensive threshold set in the database, the uniformity during laser transmission is qualified.

[0021] Furthermore, the calculation formula of the deviation comprehensive value is as follows:

[0022]

Even if slight deviations occur during use, the system can promptly detect and issue warnings to ensure the accuracy of laser irradiation.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The embodiment of the present application uses a new optical system for the laser irradiation therapy device to conduct comprehensive monitoring and inspection of each key part of the laser irradiation therapy device, including component position, operating conditions, laser status and laser transmission process, so as to timely discover and warn of potential problems and ensure the normal operation of the equipment.

[0032] See also Figure 1 An embodiment of the present invention provides a technical solution: a new optical system for a laser irradiation therapy device, including a component position inspection module, a usage condition evaluation module, a laser inspection module and a laser transmission process inspection module.

[0033] By setting up multiple inspection modules and performing inspections in the normal working order of the optical system, from component position to laser transmission, each step is interdependent to ensure the reliability of the overall system. Setting up an early warning mechanism at each key link can give prompts at the early stage of a problem to avoid greater losses or impacts caused by potential failures. Only after the previous module has passed the inspection can the next module be inspected. This step-by-step verification method reduces the risk of failure of the overall system.

[0034] The component position detection module is used to check the position of each component of the optical generating unit in the laser irradiation therapy device to determine whether the optical generating unit of the laser irradiation therapy device is normal. If it is not normal, an early warning prompt will be issued. Figure 3 As shown, the optical generating unit includes a semiconductor laser 1, a cylindrical mirror 2 and a right-angle prism 3. The cylindrical mirror 2 is used to change the laser circle into a linear shape, and then the right-angle prism 3 is used to make the light output 90 degrees with the laser. The linear light spot is irradiated on the long right-angle prism or the long reflector. After the light path is turned back at a certain angle, the linear laser is directly irradiated on the surface of the human body, which can cross the entire wrist and fully irradiate the blood vessels. Compared with point irradiation, it is inevitable to have deviations during use, and the blood vessels cannot be accurately irradiated, and the final effect will not be affected by improper personal operation.

[0035] The component position detection module checks the positions of the various components of the optical generating unit in the laser irradiation therapy device (such as semiconductor lasers, cylindrical mirrors, and right-angle prisms) to ensure that they are in the predetermined positions to ensure the correct propagation of the entire light path. Through the reasonable configuration of the cylindrical mirror and the right-angle prism, the shape of the laser can be changed from circular to linear, so that the laser can more effectively irradiate the target area of ​​the human body, especially the blood vessels. Through real-time monitoring of the component position, even if there is a slight deviation during use, the system can detect it in time and issue an early warning to ensure the accuracy of laser irradiation.

[0036] Specifically, the following steps are included: obtaining the actual position data of each component of the optical generating unit in the laser irradiation therapy device (the image of the optical component can be captured using a built-in micro camera, and the position data in the image can be analyzed through a computer vision algorithm. The image coordinates can be converted into actual space coordinates through image calibration technology). This process is the basis for ensuring the accuracy of the system. Through accurate actual position data, the operating status of the device can be comprehensively analyzed. The actual position data is compared and analyzed with the reference data of each component of the optical generating unit stored in the database to obtain the position determination parameters. The purpose of this is to quantify the deviation between the actual position and the reference position, and provide a clear quantitative basis for subsequent judgments.

[0037] The position determination parameter is compared with the position parameter stored in the database: if the position determination parameter is greater than the position parameter stored in the database, the optical generating unit of the laser irradiation therapy device is abnormal; if the position determination parameter is not greater than the position parameter stored in the database, the optical generating unit of the laser irradiation therapy device is normal.

[0038] The calculation formula of the position determination parameter is as follows:

[0039]

[0040] Where Wp is the position determination parameter, i is the number of each element of the optical generating unit, i = 1, 2, 3, ..., n, n is the total number of elements of the optical generating unit, j is the sampling point number, j = 1, 2, 3, ..., m, m is the total number of sampling points on each element, xa ij and ya ij are the actual abscissa and ordinate of the jth sampling point of the ith element, respectively, xb ij and yb ij are the parameterized abscissa and ordinate of the j-th sampling point of the ith element respectively.

[0041] Table 1 Data table of position determination parameters and laser energy output by the optical generating unit

[0042] Position determination parameters Laser intensity output by optical generating unit / mW 0.00 3.0mW 0.12 2.7mW 0.56 1.3mW 1.37 0.1mW

[0043] Taking the minimum output laser energy of 3mW as a reference, it can be seen from the data in Table 1 that the larger the position determination parameter is, the smaller the minimum output energy is, and even the laser cannot be output normally.

[0044] This closed-loop detection mechanism ensures that the equipment is in good working condition during operation. Each variable in the calculation formula reflects the deviation between the actual and reference positions. By using a combination of square roots and absolute values, the errors between different coordinate points can be effectively handled.

[0045] The usage condition evaluation module is used to determine whether the usage conditions of the laser irradiation therapy device are qualified when the optical generating unit is normal. If not, an early warning prompt will be issued.

[0046] Specifically, the method includes the following steps: obtaining the therapeutic apparatus use condition data, the therapeutic apparatus use condition data including the external temperature Ws of the therapeutic apparatus during use (which can be measured using an independent external thermometer placed near the therapeutic apparatus to obtain the ambient temperature), the standard deviation Ds of the laser input current during use (the input current data of the laser over a period of time is collected through a data acquisition system to calculate the standard deviation), and the laser usage time Ts (the laser working time can be tracked and recorded in real time through a built-in timer); judging whether Ts exceeds the limited usage time set in the database: if Ts exceeds the limited usage time set in the database, the laser irradiation therapeutic apparatus use condition is unqualified; if Ts does not exceed the limited usage time set in the database, obtaining the internal and external environment evaluation value of the therapeutic apparatus according to Ws and Ds; if the internal and external environment evaluation value of the therapeutic apparatus is greater than the internal and external environment evaluation threshold value of the therapeutic apparatus set in the database, the laser irradiation therapeutic apparatus use condition is unqualified; if the internal and external environment evaluation value of the therapeutic apparatus is not greater than the internal and external environment evaluation threshold value of the therapeutic apparatus set in the database, the laser irradiation therapeutic apparatus use condition is qualified.

[0047] By real-time monitoring and evaluation of usage conditions, factors that may affect treatment outcomes and patient safety can be discovered in a timely manner, thereby reducing the risk of accidents. By monitoring the laser's usage time and environmental conditions, it is possible to avoid working under inappropriate conditions, thereby extending the life of the equipment and reducing the frequency of repairs and updates.

[0048] Specifically, obtaining the internal and external environment evaluation value of the therapeutic device includes the following steps: obtaining the external parameter temperature Wc of the therapeutic device and the parameter standard deviation Dc of the laser input current stored in the database when the therapeutic device is in use; fusing Ws, Ds, Wc and Dc to obtain the internal and external environment evaluation value of the therapeutic device. The calculation formula of the internal and external environment evaluation value of the therapeutic device is as follows:

[0049]

[0050] Where Zp is the evaluation value of the internal and external environment of the therapeutic device.

[0051] By normalizing the absolute differences to a reference value, the relative level of the differences can be better represented, which allows variables of different magnitudes to be compared on the same scale. Adding the two relative differences above and adding 1 helps adjust the range of the results to ensure that the output is relatively stable and avoid unnecessary complexity caused by negative values.

[0052] The input current of the laser is a key factor affecting its output performance and treatment effect. Ds can measure the fluctuation degree of the input current during use, reflecting the stability and consistency of the laser during treatment. If Ds is high, it means that the input current of the laser fluctuates greatly, which may affect the laser effect and safety. The performance of the therapeutic device is greatly affected by temperature. Under different external temperature conditions, the output power, efficiency and stability of the laser may vary. Too high or too low temperature may cause thermal runaway or reduced efficiency of the laser.

[0053] When Ws changes, the electrical performance of the laser may be affected. For example, in a high temperature environment, the laser may require a higher input current to maintain the output power due to overheating. In this case, the input current also needs to be kept stable to ensure that the output of the laser is not affected, which is directly related to the effect of the therapeutic device. Conversely, when Ds is large, it indicates that the current supply of the laser is unstable, which may cause the laser output power to be more significantly affected by temperature changes, thereby exacerbating the performance fluctuations during use.

[0054] Combining the effects of Ws and Ds, a multi-dimensional environmental adaptability assessment is provided, making the results more reliable. According to the changes in Zp, the operating status of the therapeutic device can be monitored in real time, and abnormalities in accessories or environmental conditions can be discovered in time, so that measures can be taken to ensure the normal operation of the equipment.

[0055] The laser inspection module is used to determine whether the laser operation status is normal when the operating conditions are qualified. If it is abnormal, an early warning prompt will be issued.

[0056] Specifically, judging whether the operation state of the laser is normal includes the following steps: obtaining the allowable deviation data of the operation of the laser, the allowable deviation data of the operation includes the allowable deviation value of the operation temperature, the allowable deviation value of the output power, the allowable deviation value of the power consumption during operation, and the allowable deviation value of the pulse width during operation. Obtaining the actual operation data of the laser when the optical generating unit generates the laser, the actual operation data includes the actual operation temperature, the actual output power, the actual power consumption during operation, and the actual pulse width during operation. The actual operation temperature is obtained in real time by a temperature sensor installed on the laser. The actual output power is measured by a power meter, and the power meter can be directly connected to the output end of the laser to obtain the data of the actual output power. The actual power consumption during operation uses a power consumption measuring instrument (such as an electric energy analyzer) to monitor the power consumption of the laser during operation, and the actual power consumption value is obtained by real-time measurement. The actual pulse width during operation is obtained by analyzing the pulse signal emitted by the laser using a pulse width measuring instrument or an oscilloscope to obtain the actual pulse width.

[0057] Temperature is critical to the performance of the laser. Too high or too low a temperature may cause the laser to lose efficiency, drift in frequency, or even damage components. Monitoring the actual operating temperature can reflect the heat dissipation performance of the device and the tolerance of the material. Output power is one of the core performance parameters of the laser, which directly affects the application range and effect of the laser. Power consumption reflects the energy efficiency and working status of the laser. If the power consumption is abnormal, it may mean that the laser is not operating properly, there is a risk of failure or reduced efficiency. Pulse width is an important parameter of lateral modulation and laser output characteristics, which is crucial for accuracy and stability in laser applications.

[0058] The reference operating data of the laser when the optical generating unit generates laser light stored in the database is obtained, and the reference operating data includes reference operating temperature, reference output power, reference power consumption during operation, and reference pulse width during operation. The reference operating data is obtained by referring to the technical manual of the equipment, the specification documents provided by the manufacturer, or the relevant industry standards, and is stored in the database.

[0059] The operation allowable deviation data, actual operation data and reference operation data are comprehensively analyzed to obtain the laser operation status evaluation value; the laser operation status evaluation value is compared with the laser operation status evaluation threshold stored in the database: if the laser operation status evaluation value is greater than the laser operation status evaluation threshold stored in the database, the laser operation status is normal; if the laser operation status evaluation value is not greater than the laser operation status evaluation threshold stored in the database, the laser operation status is abnormal.

[0060] It can monitor the operating status of the laser in real time to ensure that it operates under appropriate working conditions and reduce the risk of failure. The early warning mechanism can detect potential problems in time, avoid possible safety hazards, and ensure safety during use.

[0061] The calculation formula of the laser operation status evaluation value is as follows:

[0062]

[0063] Wherein, Jzp is the evaluation value of the laser operation status, Sw is the actual operation temperature, Sg is the actual output power, Sh is the actual power consumption during operation, Sm is the actual pulse width during operation, Cw is the reference operation temperature, Cg is the reference output power, Ch is the reference power consumption during operation, Cm is the reference pulse width during operation, ΔW is the allowable deviation value of the operation temperature, ΔG is the allowable deviation value of the output power, ΔH is the allowable deviation value of the power consumption during operation, ΔM is the allowable deviation value of the pulse width during operation, α1 is the temperature weight factor stored in the database, α2 is the power consumption weight factor stored in the database, α3 is the pulse width weight factor stored in the database, and e is a natural constant.

[0064] In order to show the changes of the laser operating status evaluation value with the actual parameters, The value is limited to 0.8, α1 is 0.4, α2 is 0.2, α3 is 0.4, ΔW, ΔG and ΔH are all 2, such as Figure 2 As shown, it is shown that the laser operating status evaluation value gradually increases with the deviation between the actual value (Sw, Sm, where Sw has a value range of 15℃-35℃, and Sm has a value range of 30ms-70ms) and the reference value (Cw, Cm, where Cw is 25℃, and Cm is 50ms) increases, indicating that the laser operating status gradually deteriorates and differs greatly from the reference standard.

[0065] By comparing the actual operating parameters (Sw, Sg, Sh, Sm) with their reference values ​​(Cw, Cg, Ch, Cm), their degree of deviation is quantified. Each deviation term is normalized by the corresponding allowable deviation value (ΔW, ΔG, ΔH, ΔM) to ensure the relativity and consistency of the evaluation. The logarithmic function (In) and the exponential function (e) provide nonlinear responses for different parameters, which means that the system changes less when it is close to the reference value and responds quickly when it is far away from the reference value, helping to highlight abnormalities or faults. The weight factors α1, α2 and α3 in the formula are obtained from the database. A mapping set with α1, α2 and α3 is established based on the historical measurements of temperature, output power, power consumption and pulse width. α1, α2 and α3 are obtained based on the current Sw, Sg, Sh and Sm. The β in the following text d and δ can also be obtained from the database by means of mapping sets.

[0066] The power consumption of a laser is usually related to its operating temperature. Increased temperature may lead to increased power consumption, which to some extent reflects the operating efficiency and thermal management performance of the laser. There is a direct relationship between the actual output power and power consumption, and an increase in output power is often accompanied by an increase in power consumption. Monitoring these two parameters can help determine the operating efficiency of the laser. The output power is greatly affected by temperature, and excessively high operating temperatures may cause the power output to drop, so monitoring both can help identify potential problems. Pulse width affects the transfer of laser energy, which is directly related to the output power. In the application of therapeutic devices, the laser pulse width is related to the required energy output, so monitoring the pulse width can help optimize the output performance of the laser.

[0067] The formula comprehensively considers multiple key operating parameters, so that the evaluation value is not limited to a single indicator, but can fully reflect the actual operating status of the laser.

[0068] The method of obtaining the allowable deviation data of the laser operation includes the following steps: when the laser usage time does not exceed the limited usage time set in the database, the therapeutic device usage condition data is compared with the therapeutic device usage condition matching data stored in the database to obtain the operation deviation data matching index, and the therapeutic device usage condition matching data includes the external matching temperature of the therapeutic device when in use, the laser input current matching standard deviation when in use, and the laser usage matching time.

[0069] A mapping set is established between the historical measured data under different usage conditions and the allowable deviation data of the therapeutic device and stored in a database. The allowable deviation data of the current usage conditions is obtained from the database through the minimum matching index of the deviation data.

[0070] The calculation formula of the running deviation data matching index is:

[0071] Yz=e |Ws-Wp|+|Ds-Dp|+|Ts-Tp| ;

[0072] Where Yz is the running deviation data matching index, Wp is the external matching temperature of the therapeutic device when in use, Dp is the matching standard deviation of the laser input current when in use, Tp is the matching time of the laser, and e is a natural constant.

[0073] The laser transmission process inspection module is used to determine the state of the laser generated by the laser during the transmission process when the laser is operating normally, and to determine whether the uniformity during the laser transmission process is qualified. If qualified, the laser continues to generate laser; if unqualified, the laser stops generating laser and issues an early warning prompt.

[0074] Specifically, the method includes the following steps: matching the laser reference uniformity when each element in the optical generating unit receives the laser and the laser reference uniformity irradiated on the skin from a database based on the actual operating temperature and the actual output power. The database stores a mapping set of the operating temperature and output power of the laser based on historical measurements and the laser reference uniformity when each element receives the laser and the laser reference uniformity irradiated on the skin. The laser reference uniformity when each element receives the laser and the laser reference uniformity irradiated on the skin can be directly obtained from the mapping set according to the current actual operating temperature and actual output power. The specific process is to compare the current actual operating temperature and actual output power with the temperature and output power in the mapping set, find the temperature and output power that are the same as the actual operating temperature and actual output power, and obtain the reference uniformity of each laser.

[0075] Obtain the actual uniformity of the laser when each element in the optical generating unit receives the laser and the actual uniformity of the laser irradiated on the skin (by arranging high-precision light intensity sensors at different positions, using these sensors to measure the light intensity at different points in real time when the laser is working, and recording it in real time to form a two-dimensional or three-dimensional light intensity distribution diagram, and using data analysis software to perform statistical analysis on the measured light intensity to obtain the uniformity); compare each laser reference uniformity with the corresponding laser actual uniformity. If the deviation between any laser reference uniformity and the corresponding laser actual uniformity is greater than the deviation threshold set in the database, the uniformity during the laser transmission process is unqualified; if the deviation between any laser reference uniformity and the corresponding laser actual uniformity is not greater than the deviation threshold set in the database, a deviation comprehensive value is obtained based on each deviation; if the deviation comprehensive value is greater than the deviation comprehensive threshold set in the database, the uniformity during the laser transmission process is unqualified; if the deviation comprehensive value is not greater than the deviation comprehensive threshold set in the database, the uniformity during the laser transmission process is qualified.

[0076] The calculation formula of the comprehensive deviation value is as follows:

[0077]

[0078] Where Zh is the comprehensive deviation value, d is the number of the component receiving the laser, d = 1, 2, 3, ..., D, D is the total number of components receiving the laser, Y d is the deviation corresponding to the Dth element receiving the laser, β d Y stored in the database d The weight factor, y p is the deviation corresponding to the laser irradiation on the skin, and δ is the y stored in the database pThe weight factor is: L is the actual distance between the laser output end of the therapeutic device and the skin, which can be obtained through the distance detector; L0 is the reference distance between the laser output end of the therapeutic device and the skin stored in the database, which can be determined by empirical method (analyzing the irradiation effect of therapeutic devices at different distances to determine the appropriate distance); ΔL is the allowable deviation distance between the laser output end of the therapeutic device and the skin stored in the database. d is the absolute value of the difference between the laser reference uniformity of the Dth laser receiving element and the corresponding actual laser uniformity, y p It is the absolute value of the difference between the reference uniformity of the laser irradiated on the skin and the actual uniformity of the laser irradiated on the skin.
