Existing infrared photothermal devices typically employ single-band or multi-band independent irradiation, controlling the intensity of the thermal effect by adjusting the power of the light source.
[0003] However, existing infrared photothermal instruments often use a fixed power output mode when operating at different depths, and cannot flexibly adjust the energy distribution of each wavelength light source according to actual needs. This results in excessive energy concentration on the surface when operating at shallow depths, while the energy cannot effectively reach the target depth when operating at deep depths, making it difficult to meet the personalized needs of different operating depths. Summary of the Invention

Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0013] The terms "comprising" and "having," and any variations thereof, used in the embodiments of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.
[0014] To facilitate understanding of this embodiment, a control method for an infrared photothermal instrument disclosed in this embodiment will first be described in detail. The infrared photothermal instrument includes a composite light source module, which includes multiple light source units that emit beams of different wavelengths. Figure 1 As shown, this method includes the following steps: 101. Obtain the required parameters and determine the power allocation relationship of each light source unit based on the required parameters; In this embodiment, obtaining the demand parameters and determining the power allocation relationship of each light source unit based on the demand parameters includes: obtaining the demand parameters, which include the target operating depth and the demand type; calculating the band weight coefficient corresponding to each light source unit based on the target operating depth and the demand type, wherein the target operating depth is positively correlated with the band weight coefficient of the long-wavelength light source unit, and the target operating depth is negatively correlated with the band weight coefficient of the short-wavelength light source unit, and different demand types correspond to different band weight coefficient correction values; calculating the allocated power of each light source unit based on each band weight coefficient and the total output power to obtain the power allocation relationship of each light source unit.
[0015] Specifically, after startup, the infrared photothermal instrument first obtains the required parameters through a human-machine interface or a preset program. These required parameters include the target depth and the type of requirement.
[0016] Target depth of action refers to the tissue depth to which the composite beam needs to reach, which can be superficial, intermediate, or deep tissue. Demand type distinguishes different application scenarios, such as superficial repair, deep anti-inflammatory treatment, and pain relief; the corresponding band energy allocation strategies differ for different demand types.
[0017] After obtaining the required parameters, the band weighting coefficients for each light source unit are calculated based on the target depth and the type of requirement. This calculation process is based on the propagation characteristics of different wavelength beams in tissue: long-wavelength light (such as near-infrared light) has less scattering and absorption in tissue, thus achieving greater penetration depth; while short-wavelength light (such as blue light) is more easily absorbed by surface tissue and is suitable for shallow action.
[0018] Based on this principle, when calculating the band weighting coefficients, the weight allocation of each band is adjusted according to the target's depth of influence. When the target's depth of influence is large, the system increases the weighting coefficient of the long-wavelength light source unit and decreases the weighting coefficient of the short-wavelength light source unit; conversely, when the target's depth of influence is small, the weighting ratio of the short-wavelength band is increased.
[0019] It's important to note that different demand types correspond to different band weighting coefficient correction values. This is because even with the same depth of action, different application scenarios have different energy requirements for each band. For example, deep anti-inflammatory treatment may require more concentrated near-infrared energy, while tissue repair requires a balanced configuration of mid-band and long-band energy. Therefore, after calculating the basic weighting coefficients, corresponding correction values are extracted from a preset correction parameter library based on the demand type to adjust the weighting coefficients for each band.
[0020] After obtaining the band weighting coefficients of each light source unit, the specific power that each light source unit should be allocated is calculated based on these weighting coefficients and the total output power of the system. This allocation process ensures that the output power of each light source unit is proportional to its weighting coefficient, so that the energy distribution of the composite beam after being combined by the composite dichroic mirror can match the target's depth of action.
[0021] Furthermore, the step of calculating the band weight coefficient corresponding to each light source unit based on the target depth of action and the demand type includes: calculating the basic weight coefficient of each light source unit based on the target depth of action and the wavelength value corresponding to each light source unit; obtaining the corresponding band correction coefficient from a preset correction parameter library based on the demand type; and calculating the band weight coefficient corresponding to each light source unit based on the basic weight coefficient and the band correction coefficient.
[0022] Specifically, the calculation of the basic weighting coefficients is based on the depth-band mapping relationship. Internally, a depth-band mapping table is pre-stored, recording the penetration capability assessment values of each wavelength light source at different target depths. Once the system obtains the target depth, it retrieves the corresponding penetration capability assessment value from the mapping table based on the wavelength value of each light source unit, and uses this assessment value as the basic weighting coefficient.
[0023] For example, suppose the system is configured with three light source units with wavelengths of 415nm, 630nm, and 810nm. When the target depth is shallow, the penetration capability assessment value corresponding to 415nm in the mapping table is higher, so its basic weight coefficient is larger; while when the target depth is deep, the assessment value corresponding to 810nm is higher, and its basic weight coefficient increases accordingly. This mapping relationship reflects the adaptability of different wavelength beams to different depth requirements.
[0024] After obtaining the basic weight coefficients, the corresponding band correction coefficients are further obtained from the preset correction parameter library according to the type of requirement.
[0025] The correction parameter library is pre-set according to the actual needs of different application scenarios. This library stores the correspondence between various demand types and correction coefficients for each band. For example, for the demand type of "deep anti-inflammatory," the correction parameter library may set a larger positive correction coefficient for the near-infrared band to enhance the deep thermal effect; while for the "shallow repair" type, it may set a larger positive correction coefficient for the red band to promote surface tissue regeneration.
[0026] Based on the currently obtained demand type, matching records are retrieved from the correction parameter library, and the corresponding band correction coefficients for each band are extracted. These correction coefficients can be positive, indicating an increase in the weight of that band; negative, indicating a decrease in the weight of that band; or zero, indicating no correction. Based on the basic weight coefficients and the band correction coefficients, the final band weight coefficients for each light source unit are calculated.
[0027] The specific calculation method involves combining the base weighting coefficient and the band correction coefficient. In one implementation, the two can be added together to obtain the final band weighting coefficient; in another implementation, the base weighting coefficient can be multiplied by an adjustment factor determined by the band correction coefficient. In this way, the system can, based on the target's depth of action, further refine the energy allocation of each band according to specific application requirements, ensuring that the final power allocation scheme meets both depth requirements and the specific needs of the application scenario.
[0028] 102. Control each light source unit according to the power distribution relationship so that the beams output by each light source unit are combined by the composite dichroic mirror to form a composite beam. In this embodiment, after obtaining the power allocation relationship of each light source unit, the driving control of each light source unit is performed according to the power allocation relationship.
[0029] Specifically, the corresponding driving current or driving voltage is first calculated based on the power value allocated to each light source unit. Since different types of light source units (such as LEDs and laser diodes) have different photoelectric conversion characteristics, the power value is converted into corresponding driving parameters according to the photoelectric characteristic curve of each light source unit.
[0030] Furthermore, the driving circuit applies corresponding driving signals to each light source unit, causing each light source unit to output a beam of light in the corresponding wavelength according to the set power. During the driving process, the output power can also be monitored in real time to ensure that the actual output power of each light source unit matches the allocated power.
[0031] The beams output from each light source unit then enter the composite dichroic mirror. This composite dichroic mirror has selective transmission and reflection characteristics for beams of different wavelengths, enabling it to spatially combine beams from different light source units. After passing through the composite dichroic mirror, the originally dispersed beams of multiple wavelengths are integrated into a single coaxial output composite beam.
[0032] The composite beam contains the energy output by each band of light source according to the power distribution relationship, so that when the composite beam illuminates the target area, it can form an energy distribution that matches the required parameters.
[0033] 103. Adjust the output mode of the composite beam according to the required parameters, and control the composite beam to illuminate the target area corresponding to the required parameters.
[0034] In this embodiment, adjusting the output mode of the composite beam according to the demand parameters and controlling the composite beam to irradiate the target area corresponding to the demand parameters includes: determining the output mode of the composite beam according to the target depth and the range of the target area in the demand parameters; calculating the irradiation time allocation of the composite beam according to the output mode to obtain the irradiation duration corresponding to each stage, wherein the greater the target depth, the higher the proportion of the irradiation duration in the depth stage; calculating the irradiation position sequence according to the irradiation duration of each stage and the range of the target area; and controlling the composite beam to irradiate different positions of the target area sequentially according to the irradiation position sequence and the irradiation duration.
[0035] Specifically, after forming the composite beam, its output mode needs to be adjusted according to the required parameters to ensure that the irradiation process meets the actual application requirements. The output mode of the composite beam is determined based on the target depth and area of effect in the required parameters.
[0036] The output mode defines the operational state arrangement of the composite beam throughout the irradiation process. In this embodiment, the output mode can be divided into multiple stages, such as an initial stage, a depth-effect stage, and a consolidation stage. Different stages correspond to different irradiation strategies to adapt to the energy absorption characteristics of the tissue at different time periods.
[0037] The focus of each stage is determined based on the target depth. When the target depth is large, the deep treatment stage requires a longer time to ensure that energy is fully delivered to deep tissues; while when the target depth is small, the deep treatment stage can be relatively shortened, and the duration of the initial or consolidation stage can be increased. Additionally, the size of the treatment area will be considered to determine whether zonal irradiation or a mobile irradiation approach is necessary.
[0038] After determining the output mode, the irradiation time allocation of the composite beam is further calculated based on the output mode to obtain the irradiation duration corresponding to each stage.
[0039] Specifically, based on preset time allocation rules and the target depth of action, the time allocation ratio for each stage is calculated. The greater the target depth, the higher the proportion of irradiation time allocated to the deeper stages. This is because deeper tissues require a longer energy accumulation time to achieve the desired thermal effect. The calculation also considers the limitation of the total irradiation time to ensure that the sum of the durations of each stage does not exceed the set total duration.
[0040] The irradiation position sequence is calculated based on the irradiation duration and effective area range of each stage. When the effective area is large, a single irradiation may not cover the entire area. In this case, the area needs to be divided into multiple sub-regions, and the irradiation order of each sub-region needs to be determined. Based on the shape and size of the effective area, combined with the irradiation spot size of the composite beam, the area is divided into several irradiation sub-regions. Then, the system allocates a corresponding dwell time to each sub-region according to the irradiation duration of each stage, generating an irradiation position sequence containing both position and time information.
[0041] The composite beam is controlled to sequentially irradiate different positions within the target area according to the irradiation position sequence and duration. During irradiation, the position of the irradiation head of the infrared photothermal instrument is adjusted, or an optical deflection device is used, to move the composite beam according to a predetermined position sequence and remain at each position for a corresponding duration. This time-segmented and zoned irradiation method ensures that the entire target area receives sufficient energy irradiation while allowing for flexible adjustment of the irradiation strategy according to the needs of different stages, resulting in a more uniform and controllable energy distribution of the composite beam.
[0042] Furthermore, the step of calculating the irradiation position sequence based on the irradiation duration of each stage and the range of the effective area includes: dividing the effective area into multiple irradiation sub-regions by dividing the effective area into grids based on the range of the effective area and the size of the irradiation spot of the composite beam; calculating the irradiation time corresponding to each irradiation sub-region based on the irradiation duration of each stage and the number of irradiation sub-regions; and generating the irradiation position sequence based on the spatial location of the irradiation sub-regions and the irradiation time corresponding to each irradiation sub-region.
[0043] Specifically, the system acquires the geometric parameters of the target area, including its length, width, and diameter. Simultaneously, it acquires the size of the illumination spot of the composite beam, which is typically determined by the optical design of the light source module and the illumination distance. The target area is then divided into a grid according to the illumination spot size, ensuring that the size of each grid cell matches or is slightly smaller than the illumination spot, thereby guaranteeing that each grid area is adequately illuminated. Each of these grid cells constitutes an illumination sub-region.
[0044] It should be noted that the grid can be divided into regular rectangular grids or irregular grids depending on the actual shape of the area of effect. For irregularly shaped areas of effect, the main areas can be divided regularly first, and the edge areas can be divided supplementarily to improve the area coverage.
[0045] After completing the grid division, the irradiation time corresponding to each irradiation sub-region is calculated based on the irradiation duration of each stage and the number of irradiation sub-regions.
[0046] Because the entire irradiation process is divided into multiple stages, each with its own irradiation duration, different irradiation sub-regions may require different irradiation times at different stages. During calculation, the irradiation duration of each stage is either evenly distributed among the irradiated sub-regions or differentiated based on the sub-region's location within the target area (e.g., central or peripheral region). In this way, each irradiated sub-region obtains one or more time parameters, corresponding to different irradiation stages.
[0047] Then, an illumination position sequence is generated based on the spatial location of the irradiated sub-regions and the corresponding illumination time for each sub-region. When generating the illumination position sequence, the access order of each irradiated sub-region needs to be determined. A common approach is to arrange them according to the principle of spatial proximity, that is, to prioritize irradiating adjacent sub-regions to reduce the distance and time the beam travels. Another approach is to arrange them according to the principle of energy balance, that is, to alternately irradiate different regions to avoid excessive energy concentration in local areas within a short period. The spatial coordinates, illumination order, and corresponding illumination time of each irradiated sub-region are integrated to form a complete illumination position sequence. This sequence contains all the positions that the composite beam needs to irradiate sequentially and their dwell times.
[0048] In this embodiment, by acquiring the required parameters and determining the power distribution relationship of each light source unit based on these parameters, the light source units are controlled according to the power distribution relationship, so that the beams output by each light source unit are combined by a compound dichroic mirror to form a composite beam. The output mode of the composite beam is adjusted according to the required parameters to control the composite beam to illuminate the target area corresponding to the required parameters. This method dynamically determines the power distribution relationship of each band based on the required parameters, achieving flexible configuration of energy in different bands. This ensures that the energy distribution of the combined composite beam matches the target depth, avoiding the problem of excessive energy concentration at the surface during shallow action and insufficient energy reaching the target depth during deep action, thus meeting the personalized needs of different action depths.
[0049] Please see Figure 2 Another embodiment of the control method for the infrared photothermal instrument in this application includes: 201. Obtain the demand parameters and determine the power distribution relationship of each light source unit based on the demand parameters; In this embodiment, step 201 is similar to step 101 in the first embodiment, and will not be described again here.
[0050] 202. Calculate the output parameters of each light source unit based on the power distribution relationship and the preset optical action model; In this embodiment, after obtaining the power distribution relationship, the distributed power is not directly used as the output parameter of each light source unit. Instead, it is further calculated in combination with a preset optical action model to obtain more accurate output parameters.
[0051] The optical interaction model is a computational model characterizing the propagation characteristics of light beams of different wavelengths within a target region. This model comprehensively considers the optical properties of tissue, including the absorption, scattering, and attenuation patterns of light beams of different wavelengths within the tissue. When calling this model, the wavelength values and power distribution relationships corresponding to each light source unit are passed as input parameters.
[0052] The optical action model calculates the energy density distribution of beams at different depths within the target area for each wavelength band based on the input wavelength and power information. Because different wavelength bands exhibit varying propagation behaviors within tissue, the same input power can result in different energy distributions at different depths. Through model calculations, the energy arrival of each wavelength band during actual irradiation can be predicted.
[0053] After obtaining the energy density distribution, it is compared with a preset target energy threshold. The target energy threshold is set according to different application scenarios and represents the energy level that the target area needs to achieve. If the energy density calculated by the model is lower than the target threshold, the output power of the light source unit will be increased accordingly; otherwise, it will be appropriately reduced. In this way, the required output power of each light source unit is recalculated.
[0054] In addition, the output duration is calculated based on the required output power of each light source unit. The setting of the output duration takes into account the energy accumulation effect, that is, the tissue needs to absorb enough energy after the beam irradiates for a certain period of time. For light source units that require higher output power, their output duration can be appropriately shortened to avoid local overheating; while for light source units with lower output power, the output time can be extended to ensure sufficient energy transfer.
[0055] 203. Generate driving signals for each light source unit according to the output parameters, and drive each light source unit to output a light beam according to the driving signals; In this embodiment, the generation of the driving signal requires conversion based on the electrical characteristics of each light source unit. Different types of light source units have different current-voltage characteristic curves and internally store characteristic parameters of each light source unit, including operating voltage range, current-to-optical power conversion relationship, etc. Based on the output power value in the output parameters, the driving current or driving voltage to be applied is determined by querying or calculation.
[0056] For LED-type light source units, a constant current driving method is typically used, meaning the required driving current value is calculated based on the target output power. For laser diode-type light source units, in addition to controlling the driving current, the threshold current and operating point settings also need to be considered to ensure that the laser operates in a stable lasing state.
[0057] When generating the drive signal, the pulse width or duration of the drive signal is also set according to the output duration in the output parameters. For light source units that require continuous output, the drive signal maintains a stable amplitude; for light source units that require pulse output, the drive signal is modulated according to the set duty cycle and frequency.
[0058] The generated driving signal is applied to each light source unit through the driving circuit. The driving circuit converts the control signal into actual current or voltage output, driving each light source unit to emit light. During the driving process, the actual operating status of each light source unit, including parameters such as output optical power and operating temperature, can be monitored through the feedback circuit. If necessary, the driving signal can be dynamically adjusted to maintain output stability.
[0059] 204. The composite dichroic mirror is used to combine the light beams output from each light source unit to obtain a composite light beam; In this embodiment, controlling each light source unit according to the power distribution relationship to form a composite beam after the beams output by each light source unit are combined by the composite dichroic mirror includes: calculating the output parameters of each light source unit according to the power distribution relationship and a preset optical action model, wherein the optical action model characterizes the propagation characteristics of beams of different wavelengths in the target area; generating a driving signal for each light source unit according to the output parameters, and driving each light source unit to output beams according to the driving signal; and combining the beams output by each light source unit through the composite dichroic mirror to obtain a composite beam.
[0060] Specifically, each light source unit outputs a beam of light in the corresponding wavelength band under the action of the driving signal. These beams need to be combined by a composite dichroic mirror to form a coaxial output composite beam.
[0061] A composite dichroic mirror is a wavelength-selective optical element that exhibits different transmittance and reflectance for light beams of different wavelengths. In this embodiment, the composite dichroic mirror employs a multilayer dielectric film structure, achieving high transmittance or high reflectance for specific wavelength light beams by precisely controlling the film thickness and refractive index.
[0062] The light beams output from each light source unit are incident on the composite dichroic mirror from different angles. Taking three light source units as an example, the light beam output from the short-wavelength light source unit (such as 415nm blue light) may be incident from the side, and after passing through the composite dichroic mirror, it will be reflected, changing its propagation direction; the light beam output from the mid-wavelength light source unit (such as 630nm red light) is incident from another angle, part of which passes through the composite dichroic mirror and part of which is reflected; the light beam output from the long-wavelength light source unit (such as 810nm near-infrared light) may pass directly through the composite dichroic mirror.
[0063] By rationally designing the spatial layout of each light source unit and the angle of the composite dichroic mirror, three beams of light of different wavelengths ultimately propagate along the same optical axis, forming a spatially overlapping composite beam. This coaxial beam combining method ensures that the light energy of each wavelength is highly overlapped in space, so that when the composite beam illuminates the target area, the energy of each wavelength can act on the same position simultaneously.
[0064] Because the transmittance and reflectance of the composite dichroic mirror differ across different wavelengths, the beams output from each light source unit may experience some energy loss after passing through the composite dichroic mirror. Therefore, when calculating the output parameters in step 202, the optical action model has already considered these loss factors and pre-compensated the output power to ensure that the actual energy ratio of each wavelength in the combined beam matches the power distribution relationship.
[0065] The composite beam obtained after being combined by the dichroic mirror contains light energy from multiple wavelengths from each light source unit, and these energies are combined according to a pre-calculated power distribution relationship. This composite beam can then illuminate the target area, achieving energy transfer at different depths.
[0066] 205. Adjust the output mode of the composite beam according to the required parameters, and control the composite beam to illuminate the target area corresponding to the required parameters.
[0067] In this embodiment, step 205 is similar to step 103 in the first embodiment, and will not be described again here.
[0068] In this embodiment, by acquiring the required parameters and determining the power distribution relationship of each light source unit based on these parameters, the light source units are controlled according to the power distribution relationship, so that the beams output by each light source unit are combined by a compound dichroic mirror to form a composite beam. The output mode of the composite beam is adjusted according to the required parameters to control the composite beam to illuminate the target area corresponding to the required parameters. This method dynamically determines the power distribution relationship of each band based on the required parameters, achieving flexible configuration of energy in different bands. This ensures that the energy distribution of the combined composite beam matches the target depth, avoiding the problem of excessive energy concentration at the surface during shallow action and insufficient energy reaching the target depth during deep action, thus meeting the personalized needs of different action depths.
[0069] The control method of the infrared photothermal instrument in the embodiments of the present invention has been described above. The control device of the infrared photothermal instrument in the embodiments of the present invention is described below. The infrared photothermal instrument includes a composite light source module, which includes multiple light source units emitting beams of different wavelengths, and a composite dichroic mirror that coaxially combines the beams of the multiple light source units.

Figure 3 One embodiment of the control device for the infrared photothermal instrument in this invention includes: The parameter acquisition module 301 is used to acquire the required parameters and determine the power distribution relationship of each light source unit based on the required parameters. The beam combining module 302 is used to control each light source unit according to the power distribution relationship, so that the beams output by each light source unit are combined by the composite dichroic mirror to form a composite beam. The mode adjustment module 303 is used to adjust the output mode of the composite beam according to the required parameters, and control the composite beam to illuminate the target area corresponding to the required parameters.
[0070] In this embodiment of the invention, the control device of the infrared photothermal instrument operates the aforementioned control method for the infrared photothermal instrument. The control device acquires the required parameters and determines the power distribution relationship of each light source unit based on these parameters. It then controls each light source unit according to the power distribution relationship, causing the beams output by each light source unit to be combined by a composite dichroic mirror to form a composite beam. Finally, it adjusts the output mode of the composite beam according to the required parameters, controlling the composite beam to irradiate the target area corresponding to the required parameters. This method dynamically determines the power distribution relationship of each band based on the required parameters, achieving flexible configuration of energy in different bands. This ensures that the energy distribution of the combined composite beam matches the target depth, avoiding the problem of excessive energy concentration at the surface during shallow applications and insufficient energy reaching the target depth during deep applications, thus meeting the personalized needs of different application depths.
