Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a laser therapy device and a laser therapy method. Background Art

[0002] Semiconductor laser therapy is a diode laser. When the laser beam generated irradiates biological tissue, it can produce photoelectromagnetic effect, photothermal effect, biostimulation effect, photochemical effect, etc. Laser can be used to carbonize, vaporize, cut, burn, repair and other functions of the target soft tissue based on these characteristics and effects. The semiconductor laser therapy device currently used generally includes a host, a handle and an optical fiber working end. The laser is emitted from the host and then transmitted to the optical fiber working end through the handle, and finally acts on the patient's tissue. The working principle of semiconductor laser is that after the laser output to the tip of the optical fiber working tip is charred (activated) (through a dark object, such as bite paper), the tip of the optical fiber working tip will be heated to several hundred degrees due to the irradiation of the laser beam. When the temperature of the soft tissue in contact reaches 110°C or above due to the contact of the optical fiber working end, the soft tissue will be vaporized / carbonized due to the thermal effect. In this way, the patient's soft tissue is cut by the high-temperature optical fiber working tip. When the soft tissue is cut, part of the laser is irradiated to the wound surface, which can simultaneously achieve the effects of cutting, anti-inflammatory, hemostasis, analgesia, sterilization, and healing promotion, thereby achieving a therapeutic effect.

[0003] However, when the semiconductor laser therapy device in the prior art is used for treatment, the temperature of the optical fiber working section will be high due to various reasons such as excessive laser power, poor laser irradiation time and slow laser movement speed, resulting in increased wound area and depth, increased carbonization amount, prolonged wound healing time and other unfavorable conditions for the patient, resulting in poor treatment effect of the current laser therapy device. Summary of the invention

[0004] In view of this, the purpose of the embodiments of the present application is to provide a laser therapy device and a laser therapy method to improve the problem of poor treatment effect of laser therapy devices in the prior art.

[0005] In order to solve the above problems, in a first aspect, the present application provides a laser therapeutic device, the laser therapeutic device comprising: a working module, a temperature module and a processing module;

[0006] The temperature module is used to detect the pulse data of the operating area when the working module is working;

[0007] The processing module is used to determine the working temperature of the working module when it is working according to the pulse data;

[0008] The processing module is further used to adjust the output power of the laser in the working module according to the working temperature to obtain the adjusted laser;

[0009] The working module is used to treat the surgical area according to the adjusted laser.

[0010] In the above implementation process, by setting a temperature module in the laser therapy device, the laser signal of the surgical area when the working module is working can be detected, and the corresponding pulse data can be obtained and sent to the processing module, and the pulse data can be converted into the working temperature of the working module. The processing module adjusts the output power of the working module when it is working according to the working temperature, so that the working module can adjust the laser after adjustment, thereby adjusting the temperature of the surgical area when the working module is working. The temperature of the laser output by the working module during treatment can be detected and adjusted, and the non-contact detection of temperature improves the accuracy and effectiveness of temperature detection. It can also effectively control the temperature according to the actual situation during the treatment process, reducing the adverse effects of the laser temperature being too high or too low on the patient's treatment process, improving the treatment effect of the laser therapy device, and improving the user experience of medical staff and the treatment experience of patients.

[0011] Optionally, the temperature module includes a temperature sensor for detecting the surgical area to obtain detection data;

[0012] The temperature module is used to calculate the corresponding pulse data according to the detection data, so as to send the pulse data to the processing module.

[0013] In the above implementation process, the laser signal in the operating area is detected by the temperature sensor in the temperature module. Based on the detection data obtained, the pulse data related to the temperature can be calculated and sent to the processing module, so that the temperature of the operating area when the working module is working can be timely detected and fed back, thereby improving the accuracy and real-time performance of temperature detection.

[0014] Optionally, the laser therapy device includes a display module for displaying the working temperature obtained from the processing module;

[0015] If the operating temperature is within the prompt temperature range, the display module is used to display temperature warning information;

[0016] If the operating temperature is greater than the temperature threshold, the processing module is used to control the laser to stop outputting, and the display module is used to display a stop prompt message.

[0017] In the above implementation process, the working temperature detected in the processing module is obtained and displayed by the display module in the laser therapy device, so that medical staff can view and understand the temperature. In addition, different operations and displays are performed according to different working temperatures, and temperature warning information can be generated and displayed for working temperatures within the prompt temperature range; laser stop prompt information is generated and displayed for working temperatures greater than the temperature threshold, and the laser output is automatically stopped when the temperature is too high to prompt medical staff of temperature changes, and the laser treatment process is thermally protected, reducing the adverse conditions caused to patients by laser output due to inappropriate temperature, and improving the visibility and safety of laser therapy during treatment.

[0018] Optionally, the adjustment laser includes a temperature increasing laser and a temperature decreasing laser;

[0019] The processing module is used to obtain the working temperature range of the working module;

[0020] If the working temperature is lower than the working temperature range, the processing module is used to increase the output power of the laser in the working module to increase the working temperature and obtain the temperature-increasing laser;

[0021] If the working temperature is higher than the working temperature range, the processing module is used to reduce the output power of the laser in the working module to lower the working temperature and obtain the cooling laser.

[0022] In the above implementation process, the processing module adjusts the working temperature accordingly according to the relationship between the working temperature and the working temperature range. Since the output power of the laser is proportional to the working temperature of the working module, the output power is increased or decreased according to different working temperatures, thereby increasing or decreasing the working temperature to obtain the adjusted temperature-increasing laser and temperature-reducing laser. The output power of the laser can be automatically adjusted according to the working temperature detected, thereby adjusting the working temperature, so that the working module can work at a stable temperature, thereby improving the controllability and stability of the temperature of the working module when it is working.

[0023] Optionally, the laser therapeutic apparatus comprises a detection module and an optical path component, the detection module is connected to the processing module, and the optical path component is arranged in a handle;

[0024] The optical path component is used to transmit the laser output from the processing module to the working module;

[0025] The detection module is used to detect the optical path component to obtain optical path data;

[0026] The processing module is used to determine whether the optical path components are connected according to the acquired optical path data.

[0027] In the above implementation process, the handle of the laser therapy device is provided with an optical path component that transmits the laser from the processing module to the working module for treatment. Considering the risk of a broken circuit in the optical path component, a detection module can be provided in the laser therapy device to detect the laser in real time, so that the processing module can detect whether the optical path component through which the laser in the handle passes is conductive based on the obtained optical path data, thereby determining whether the optical path of the laser is conductive, reducing the adverse effects caused by the continuous output of the laser at the disconnected position of the optical path component when the optical path is disconnected, and improving the safety of laser treatment.

[0028] Optionally, the detection module is provided with an illumination component, which is used to obtain a trigger voltage according to the illumination intensity of the laser in the optical path component:

[0029] The detection module is used to obtain the trigger voltage in the illumination component;

[0030] The detection module is further used to determine the optical path data when the laser passes through the optical path component according to the trigger voltage and the voltage threshold in the detection module.

[0031] In the above implementation process, the illumination component outputs a corresponding trigger voltage according to the illumination intensity of the laser irradiated in the optical path component, and the corresponding optical path data can be obtained according to the trigger voltage and the voltage threshold used for reference when there is no laser irradiation. The passage of the laser in the optical path component can be accurately reflected according to the illumination intensity, and whether the optical path component is turned on can be detected quickly and accurately.

[0032] Optionally, the detection module is used to send the optical path data to the processing module;

[0033] If the trigger voltage is greater than the voltage threshold, the optical path component is turned on, and the processing module is used to control the laser to output normally in the optical path component;

[0034] If the trigger voltage is less than or equal to the voltage threshold, the optical path component is disconnected, and the processing module is used to control the laser to stop outputting.

[0035] In the above implementation process, after determining the optical path data, the detection module sends it to the processing module, so that the processing module can detect and compare the trigger voltage and voltage threshold in the optical path data. According to the different relationships between the trigger voltage and the voltage threshold, it is determined whether the illumination component is irradiated by the laser, thereby determining whether the optical path component is turned on. And according to different situations in the optical path component, it is controlled whether the laser is output normally, and the laser output can be stopped in time when the circuit is broken, which effectively reduces the damage to the device and personnel caused by the continuous output of the laser when the optical path component is disconnected, and improves the safety during laser treatment.

[0036] Optionally, the laser therapy device includes a lighting module for illuminating the surgical area;

[0037] The processing module is used to adjust the lighting brightness of the lighting module according to the pulse data;

[0038] Alternatively, the processing module is used to adjust the lighting brightness of the lighting module according to the acquired brightness requirement.

[0039] In the above implementation process, taking into account the dark environment in the operating area during laser treatment, a lighting module is set in the laser therapy device to illuminate the operating area, which can improve the regional visibility when the laser therapy device performs laser treatment. The processing module can also adjust the lighting brightness of the lighting module accordingly according to pulse data or brightness requirements obtained by medical staff based on actual conditions, thereby achieving control of the lighting, facilitating operations for medical staff, reducing the difficulty of surgery, improving the accuracy of surgery, and thus improving the therapeutic effect of laser treatment.

[0040] In a second aspect, the present application also provides a laser treatment method, which is applied to a laser therapy apparatus, and the method comprises:

[0041] Through the temperature module, the pulse data of the surgical area when the working module is working is detected;

[0042] Determine, by a processing module, a working temperature of the working module when the working module is working according to the pulse data;

[0043] By means of the processing module, the output power of the laser in the working module is adjusted according to the working temperature to obtain an adjusted laser;

[0044] The operating area is treated by the working module according to the adjusted laser.

[0045] In the above implementation process, the pulse data of the laser in the surgical area is detected and transmitted to calculate the working temperature of the working module when it is working according to the pulse data. The non-contact detection of temperature improves the accuracy and effectiveness of temperature detection. The output power in the working module is modulated according to the working temperature to adjust the working temperature of the working module so that the working module outputs the adjusted laser as the output laser. The temperature of the laser output by the working module during treatment can be detected and adjusted, and the temperature can be effectively controlled according to the actual situation during the treatment process, reducing the adverse effects of the laser temperature being too high or too low on the patient's treatment process, improving the treatment effect of the laser therapy device, and enhancing the user experience of medical staff and the treatment experience of patients.

[0046] Optionally, the adjustment laser includes a temperature increasing laser and a temperature decreasing laser, and the processing module is used to adjust the output power of the laser in the working module according to the working temperature to obtain the adjustment laser, including:

[0047] Acquiring the operating temperature range of the working module through the processing module;

[0048] When the processing module detects that the operating temperature is lower than the operating temperature range, the processing module increases the output power of the laser in the working module to increase the operating temperature and obtain the temperature-increasing laser;

[0049] When the processing module detects that the operating temperature is higher than the operating temperature range, the processing module reduces the output power of the laser in the working module to lower the operating temperature and obtain the cooling laser.

[0050] In the above implementation process, when the output power is adjusted, since the output power of the laser is proportional to the working temperature of the working module, according to the relationship between the detected working temperature and the working temperature range of the working module, the output power can be increased or decreased based on different working temperatures, thereby increasing or decreasing the working temperature to obtain the adjusted temperature-increasing laser and temperature-reducing laser. Automatic temperature adjustment can be achieved, which improves the controllability and stability of the temperature of the working module when it is working.

[0051] In summary, the present application provides a laser therapy device and a laser therapy method. By setting a temperature module in the laser therapy device, the temperature of the laser output by the working module during treatment can be detected and adjusted, and the temperature can be effectively controlled according to the actual situation during the treatment process, thereby reducing the adverse effects of excessively high or low laser temperature on the patient's treatment process, improving the treatment effect of the laser therapy device, and enhancing the user experience of medical staff and the treatment experience of patients.

DETAILED DESCRIPTION

[0063] The technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0064] When the current laser therapy device is used for treatment, the output laser can be divided into high-energy laser and low-energy laser according to the energy level. High-energy laser has high power and may have irreversible effects on the body. It is often used for surgical treatment such as gasification and cutting of soft tissue of lesions; low-energy laser can directly irradiate biological tissue to reduce or eliminate pain, improve local blood circulation, repair tissue, and quickly reduce inflammation. It will not cause irreversible damage, so it is often used in physical therapy, that is, non-invasive medical treatment.

[0065] The thermal effect parameters of human tissue are generally: protein denaturation occurs when the temperature is higher than 68 degrees, coagulation occurs when the temperature is higher than 100 degrees, vaporization occurs when the temperature is higher than 110 degrees, and carbonization occurs when the temperature is higher than 200 degrees. Therefore, the different temperatures of the laser output in the laser therapy device will have different degrees of effect on the patient's surgical area. In the prior art, if the laser power is set too high, the continuous irradiation time process or the treatment process movement speed is slow, it will cause the temperature of the tip of the optical fiber working tip to accumulate and increase. If the operation is not done properly, it may cause the area and depth of the patient's wound, increase the carbonization amount of the patient's tissue, prolong the healing time of the wound, and other unfavorable situations, resulting in poor treatment effect of the current laser therapy device and poor treatment experience for patients.

[0066] See also Figure 1 , Figure 1 This is a schematic structural diagram of a first laser therapy device provided in an embodiment of the present application, wherein the laser therapy device comprises: a working module 100, a temperature module 200 and a processing module 300.

[0067] The temperature module 200 is used to detect the pulse data of the operation area when the working module 100 is working;

[0068] The processing module 300 is used to determine the working temperature of the working module 100 when the working module 100 is working according to the pulse data;

[0069] The processing module 300 is also used to adjust the output power of the laser in the working module 100 according to the working temperature to obtain the adjusted laser;

[0070] The working module 100 is used to treat the surgical area according to the adjusted laser.

[0071] Optionally, the laser therapy device may further include a handle 400 , wherein the working module 100 is disposed at the working end of the handle 400 , the processing module 300 is connected to the non-working end of the handle 400 via a cable, and the temperature module 200 is disposed in the handle 400 .

[0072] Optionally, the working module 100 may be the tip part of the optical fiber working tip in the laser therapy device, and the processing module 300 may include the host of the laser therapy device. When the output power of the laser input into the working module 100 by the host is higher, the temperature of the tip of the optical fiber working tip is higher, and the temperature of the operating area is also higher; during the treatment process, the temperature of the operating area is also related to the moving speed of the tip part of the optical fiber working tip. The slower the moving speed of the tip of the optical fiber working tip, the higher the temperature of the tip of the optical fiber working tip is, and the higher the temperature of the operating area is.

[0073] The temperature module 200 is electrically connected to the processing module 300, and a temperature sensor 210 may be provided in the temperature module 200. By way of example, the temperature sensor 210 may be a non-contact infrared thermopile sensor of various types, such as an MLX90616 sensor, etc., which is composed of thermocouples connected in series, with the cold end placed on a thick chip substrate of the temperature module 200, and the hot junction placed on a thin film, and heating (or cooling) is performed by infrared radiation absorbed by the film.

[0074] It is worth noting that, due to the high temperature of the laser during laser treatment, when the working temperature of the tip of the optical fiber working tip in the working module 100 is detected by contact measurement, the device may be damaged when the temperature is too high; and contact measurement requires contact with the tissue in the surgical area of ​​the patient, the accuracy of temperature measurement is low and contact will affect the laser treatment of the surgical area. Therefore, the temperature module 200 in the embodiment of the present application detects the surgical area by non-contact measurement.

[0075] The temperature sensor 210 is used to detect the surgical area and obtain detection data. For example, the detection data may be data such as infrared heat signals when laser irradiation is detected in the surgical area. The temperature module 200 is used to calculate the corresponding pulse data based on the detection data to send the pulse data to the processing module 300. The temperature module 200 can automatically calculate the pulse data related to the current temperature based on the detection data, such as the signal size in the infrared heat signal, such as a PWM (Pulse width modulation) data. Since the pulse width of the laser output corresponding to different temperatures is different, the change of the pulse data can reflect the change of temperature, so that the temperature module 200 can detect the temperature in the surgical area in real time without contact, thereby improving the accuracy, real-time and safety of temperature detection.

[0076] Optionally, the processing module 300 may include processors of various types. The processor may be an integrated circuit chip with signal processing capability, or a general-purpose processor, including a central processing unit (CPU), a microcontroller unit (MCU), a network processor (NP), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc. After the processing module 300 receives the pulse data sent by the temperature module 200, it can calculate the working temperature of the working module 100 corresponding to the pulse data when it is currently working.

[0077] For example, the calculation method of the operating temperature may include:

[0078]

[0079] Among them, T OUT is the output temperature in degrees Celsius, t2 is the pulse width in μs, T is the PWM period, which is 1004 μs, T O_MAX is the upper temperature limit, T O_MIN The lower limit of the set temperature.

[0080] Optionally, see Figure 2 , Figure 2 A circuit connection diagram of a temperature sensor 210 in a temperature module 200 provided in an embodiment of the present application, wherein the temperature sensor 210 is a non-contact infrared thermopile sensor connected to a processor 310 in a processing module 300 .

[0081] Optionally, the working voltage during operation can be set to 3.3V, and the temperature sensor 210 is connected to the Vdd terminal (power supply voltage terminal), SCL (control line), SDA (data line) and GND (ground) terminal in the processor 310 through the first resistor R1, the second resistor R2 and the first capacitor C1 set in the circuit, so as to realize the calculation and transmission of pulse data. Among them, the models and parameters of the first resistor R1, the second resistor R2 and the first capacitor C1 can be selected and adjusted according to the actual situation in the circuit.

[0082] Optionally, see Figure 3, Figure 3 This is a schematic diagram of the structure of a second laser therapy device provided in an embodiment of the present application, wherein the laser therapy device may further include a display module 500. The display module 500 is electrically connected to the processing module 300 to obtain and display the working temperature of the working module 100 calculated in the processing module 300.

[0083] For example, the display module 500 can be a variety of types of displays, which can provide an interactive interface (such as a user operation interface) for medical staff or be used to display image data for reference by medical staff. The display can be a liquid crystal display or a touch display. If it is a touch display, it can be a capacitive touch screen or a resistive touch screen that supports single-point and multi-point touch operations. Supporting single-point and multi-point touch operations means that the touch display can sense touch operations generated simultaneously from one or more positions on the touch display, and the sensed touch operations are handed over to the processor for calculation and processing.

[0084] It is worth noting that the display module 500 can also warn and prompt the temperature. Medical staff can set the temperature limit for warning and shutting down the laser output in the laser therapy instrument, with the temperature range of the warning as the prompt temperature range, and the temperature for shutting down the laser output as the temperature threshold. When the working temperature is within the prompt temperature range, the display module 500 can display the temperature warning information. For example, when the prompt temperature range is 150°C-230°C, if the working temperature is 170°C, the display module 500 will display the temperature warning information such as "the temperature is high, please operate with caution". When the working temperature exceeds the temperature threshold, the display module 500 will display the stop prompt information. For example, when the temperature threshold is 230°C, if the working temperature is 250°C, the processing module 300 will directly control the laser in the host to stop output, and the display module 500 will display the stop prompt information such as "the temperature is too high, stop laser output". It can display the working temperature in real time and issue real-time warnings based on the working temperature, remind medical staff of temperature changes, provide thermal protection for the laser treatment process, and reduce adverse conditions on patients caused by inappropriate temperature laser output, such as thermal damage to the surgical area due to high temperature, thereby accelerating the healing time of patient tissues and improving the visibility and safety of laser therapy.

[0085] Optionally, due to differences in the actual situation such as the techniques of medical staff and differences between surgeries, the cutting efficiency and effect may differ. Therefore, in order to make the temperature of the tip of the optical fiber working tip more stable, thereby making the cutting efficiency during laser treatment more stable, the processing module 300 may perform temperature control according to the detected working temperature. Medical staff can set the corresponding working temperature range in the laser therapy device according to the specific circumstances of the surgery. For example, the working temperature range may be set to 130°C-150°C (the effect of laser cutting below 130°C is poor, and the excessively high temperature of laser cutting above 150°C may cause carbonization of the patient's tissue).

[0086] Since the output power of the laser is proportional to the working temperature of the working module 100, the higher the output power of the laser, the higher the working temperature of the working module 100. Therefore, the output power of the laser can be increased or decreased according to different working temperatures, thereby increasing or decreasing the working temperature to obtain the adjusted temperature-increasing laser and temperature-reducing laser. For example, after the processing module 300 obtains the working temperature range interval set by the medical staff, the current working temperature can be compared with the working temperature range interval. When the working temperature is lower than the working temperature range interval, for example, when the working temperature is 100°C, the processing module 300 increases the power of the laser output in the host, thereby increasing the working temperature of the working module 100, and obtaining a temperature-increasing laser with increased power; when the working temperature is higher than the working temperature range interval, for example, when the working temperature is 160°C, the processing module 300 reduces the power of the laser output in the host, thereby reducing the working temperature of the working module 100, and obtaining a temperature-reducing laser with reduced power. The temperature can be automatically detected and controlled, so that the temperature of the tip of the optical fiber working tip is always stable within the set range, so that the working module 100 can work at a stable temperature, and the controllability and stability of the temperature of the working module 100 are improved. While improving the treatment effect, the carbonization of the tissue during the operation is reduced, so that the wound surface is relatively clean, and the tissue in the patient's surgical area heals faster.

[0087] For example, when the processing module 300 increases or decreases the output power of the laser, it can be adjusted by PID (Proportion Integral Differential, a controller that controls according to the proportion P, integral I and differential D of the deviation in process control), and the adjustment method can be:

[0088]

[0089] Among them, OUT is the output value, K P is the proportional gain, T is the sampling period, T i is the integration period, T Dis the differential period, err(k) is the error value, err(k-1) is the error value obtained by the previous calculation, and err1 is the accumulated error value.

[0090] Optionally, see Figure 4 , Figure 4 This is a schematic diagram of the structure of a third laser therapy device provided in an embodiment of the present application, wherein the laser therapy device may also include a detection module 600 and an optical path component 610, the detection module 600 is connected to the processing module 300, and the optical path component 610 is disposed in the handle 400.

[0091] Among them, the optical path component 610 is used to transmit the laser output from the processing module 300 to the working module 100. The optical path component 610 can be a component that can transmit laser, such as an optical fiber. The current optical fiber material is generally quartz glass, so there is a risk of optical fiber breakage. If the optical fiber is disconnected, the laser continues to accumulate heat at the location where the optical fiber is disconnected, which may cause damage to the device, burns to people in contact, and even cause fires. Therefore, a detection module 600 is set in this application to detect the optical path component 610, and send the detected optical path data to the processing module 300, so that the processing module 300 can determine whether the optical path component 610 is conductive based on the optical path data.

[0092] Optionally, when performing detection, the detection module 600 can be set at the position where the working module 100 is coupled to the optical path component 610, and an illumination component 620 can be provided in the detection module 600. The illumination component 620 obtains a corresponding trigger voltage according to the irradiation intensity of the laser in the optical path component 610, and obtains the optical path data when the laser passes through the optical path component 610 with the voltage threshold used for reference when there is no laser irradiation.

[0093] For example, the illumination component 620 can be a photosensitive device such as an infrared receiving diode that can react to laser irradiation and can receive infrared bands. When detecting the trigger voltage, the detection method may include: when a laser irradiates the illumination component 620 through the optical path component 610, the illumination component 620 will output a feedback current in real time according to the intensity of the laser irradiation; when there is no laser irradiation (that is, when the optical path component 610 is disconnected), multiple resistors in the detection module 600 can form a voltage divider circuit to output a voltage threshold for reference when there is no laser irradiation; after the illumination component 620 is connected in series with the resistor, the voltage obtained according to the feedback current is the reverse input terminal signal in the comparator, which is used as the trigger voltage, and the voltage threshold of the in-phase input terminal is used as the optical path data. It can accurately reflect the passage of the laser in the optical path component 610 according to the light intensity, and quickly and accurately detect whether the optical path component 610 is turned on.

[0094] Optionally, see Figure 5 and Figure 6, Figure 5 A circuit diagram for generating a voltage threshold provided in an embodiment of the present application is shown in FIG. Figure 6 A circuit diagram for generating a trigger voltage provided in an embodiment of the present application.

[0095] When the laser does not irradiate the illumination component 620 through the optical path component 610, the illumination component 620 in the circuit does not function. Figure 5 The voltage threshold REF can be calculated by connecting the third resistor R3, the fourth resistor R4 and the second capacitor C2. Optionally, the models and parameters of the third resistor R3, the fourth resistor R4 and the second capacitor C2 can be selected and adjusted according to the actual situation in the circuit.

[0096] When the laser is irradiated into the illumination component 620 through the optical path component 610, a trigger voltage is obtained according to the connection between the illumination component 620 and the fifth resistor R5, the sixth resistor R6, the third capacitor C3 and the comparator 621 in the circuit. The models and parameters of the fifth resistor R5, the sixth resistor R6, the third capacitor C3 and the comparator 621 can be selected and adjusted according to the actual situation in the circuit.

[0097] It is worth noting that after determining the optical path data, the detection module 600 sends it to the processing module 300, so that the processing module 300 can detect and compare the trigger voltage and voltage threshold in the optical path data, thereby determining whether the optical path component 610 is turned on and performing corresponding operations.

[0098] Optionally, the judgment and operation may include: when the trigger voltage is greater than the voltage threshold, it means that there is currently laser irradiating the illumination component 620 through the optical path component 610, then the optical path component 610 is turned on, and the comparator can output a low level signal; when the trigger voltage is less than or equal to the voltage threshold, it means that there is currently no laser irradiating the illumination component 620, then the optical path component 610 is turned off, and the comparator can output a high level signal. The output level signal can be detected by the processing module 300, and when a low level signal is detected, it is determined that the optical path of the optical path component 610 is turned on, and the laser is controlled to continue to be output in the optical path component 610; when a high level is detected, it is determined that the optical path of the optical path component 610 is disconnected, and the output of the laser can be stopped in time, which effectively reduces the damage to the device and personnel caused by the continuous output of the laser when the optical path component 610 is disconnected, and improves the safety during laser treatment.

[0099] Optionally, see Figure 7 , Figure 7 This is a schematic diagram of the structure of a fourth laser therapy device provided in an embodiment of the present application, wherein the laser therapy device may further include a lighting module 700.

[0100] The laser used in laser treatment is generally a laser in the infrared band of 980nm / 808nm. The laser used during treatment is invisible to the naked eye, or a very low-power red laser is set as an indicator light (usually less than 5mW), resulting in unclear vision during treatment. In addition, in some surgical environments, such as oral surgery, the oral environment is dark, so the visibility of the surgical area during the operation is low, which increases the difficulty and accuracy of the operation. Therefore, in the embodiment of the present application, a lighting module 700 is provided to illuminate the surgical area. For example, the lighting module 700 may include LED bulbs of various types and models, and the lighting module 700 may be turned on at the same time as the laser output during the operation.

[0101] Optionally, in order to better enhance the lighting effect of the lighting module 700 on the surgical area, the lighting module 700 may be disposed at one end of the handle 400 close to the working module 100 .

[0102] Optionally, the lighting module 700 can be connected to the processing module 300. By connecting the LED lamp to multiple devices such as resistors, the processing module 300 can automatically adjust the lighting brightness of the LED lamp in the lighting module 700 by adjusting the pulse width of the PWM wave in the pulse data detected in the temperature module 200, so that the lighting brightness changes accordingly with the change of the laser.

[0103] Optionally, the illumination brightness of the illumination module 700 can be adjusted accordingly according to the brightness requirements of the medical staff. The brightness requirements can be requirements set by the medical staff when interacting with the physical buttons or touch cases in the display module 500, such as increasing or decreasing the brightness, turning it on or off, etc. The medical staff can independently and individually turn off the illumination module 700 or adjust the illumination brightness in the illumination module 700, realize the control of the illumination, improve the visual conditions during the operation, facilitate the operation of the medical staff, reduce the difficulty of the operation, improve the accuracy of the operation, and thus improve the therapeutic effect of the laser treatment.

[0104] It is worth noting that the processing module 300 in the laser therapy device can also be connected to the terminal equipment of medical staff, hospitals or patients. The terminal equipment may include servers, personal computers (PC), tablet computers, smart phones, personal digital assistants (PDA) and other electronic devices with logical computing functions. The connection method can be network, Bluetooth and other methods, so that the user can input brightness requirements and brightness adjustment instructions in the terminal device, so that the processing module 300 can obtain the brightness requirements and adjustment instructions in the terminal device, and adjust the lighting brightness in the lighting module 700 accordingly.

[0105] Optionally, see Figure 8 , Figure 8 A circuit diagram of a lighting module 700 provided in an embodiment of the present application. The lighting module 700 is connected to a seventh resistor R7, an eighth resistor R8, a ninth resistor R9 and a control component 710, so that the lighting module 700 is adjusted by adjusting the pulse width of the PMW wave. The models and parameters of the seventh resistor R7, the eighth resistor R8, the ninth resistor R9 and the control component 710 can be selected and adjusted according to the actual situation in the circuit.

[0106] See also Fig. 9 , Fig. 9 This is a flow chart of a laser treatment method provided in an embodiment of the present application. The method is applied to a laser therapy device provided in an embodiment of the present application. The method may include steps S800-S830.

[0107] Step S800, detecting the pulse data of the operating area when the working module is working through the temperature module.

[0108] Among them, the temperature module can perform non-contact detection on the corresponding surgical area when the working module is working, and obtain pulse data related to temperature.

[0109] Step S810: determining the working temperature of the working module according to the pulse data through the processing module.

[0110] Among them, the processing module can calculate according to the pulse data and convert it into the working temperature when the working module is working.

[0111] Step S820: adjusting the output power of the laser in the working module according to the working temperature through the processing module to obtain adjusted laser.

[0112] Among them, since the output power of the laser is proportional to the working temperature, the processing module can also adjust the output power of the laser according to the working temperature, thereby adjusting the working temperature accordingly, realizing temperature control, and obtaining an adjusted laser.

[0113] Optionally, the adjustment laser includes a temperature-increasing laser and a temperature-reducing laser, and step S820 may include: obtaining the working temperature range of the working module through the processing module; when the processing module detects that the working temperature is lower than the working temperature range, increasing the output power of the laser in the working module through the processing module to increase the working temperature and obtain the temperature-increasing laser; when the processing module detects that the working temperature is higher than the working temperature range, reducing the output power of the laser in the working module through the processing module to reduce the working temperature and obtain the temperature-reducing laser. The output power can be increased or decreased based on different working temperatures, thereby increasing or decreasing the working temperature to obtain the adjusted temperature-increasing laser and temperature-reducing laser. Automatic temperature adjustment can be achieved, which improves the controllability and stability of the temperature of the working module when it is working.

[0114] Step S830: Treat the surgical area according to the adjusted laser through the working module.

[0115] Among them, the working module can work according to the adjusted laser, so as to treat the surgical area with a stable temperature, thereby improving the treatment effect of the laser.
