Technical Field

[0001] The invention relates to the technical field of laser medicine, and in particular to a multi-core hybrid laser system. Background Art

[0002] With the advancement of modern medical technology, the application field of laser medicine is developing from general disease treatment to disease prevention, disease diagnosis and disease integration. A variety of new light-controlled treatment technologies with the development purpose of precision, minimally invasive, safe and intelligent are leading the transformation of laser medical diagnosis and treatment mode.

[0003] At present, laser medicine has formed three major laser treatment technologies in clinical applications: high-intensity laser therapy, low-intensity laser therapy (LLLT) and photodynamic therapy (PDT), which have become important technologies for the treatment of clinical diseases. Among them, high-intensity laser therapy includes the use of high-energy laser irradiation to vaporize, carbonize, and ablate diseased cell tissues; low-intensity laser therapy includes the use of low-energy laser irradiation to irradiate cell tissues for physiological regulation; and photodynamic therapy includes the destruction of diseased tissues by photochemical reactions produced by combining photosensitizers and lasers of specific wavelengths. Various laser medical devices manufactured with existing lasers as core technology devices have been widely used in the treatment of various clinical diseases.

[0004] The lasers used in existing laser medical equipment generally use general-purpose lasers with simple structural types as core technical devices. They only support single-wavelength laser output and are unable to output multiple wavelengths of lasers individually, alternately or simultaneously. They are even more unable to output multiple wavelengths of lasers individually, alternately or simultaneously on the same optical fiber interface. They cannot meet the needs of high-intensity laser therapy, weak laser therapy, photodynamic therapy, and higher-level clinical medical applications, and cannot achieve integrated laser diagnosis and treatment, and cannot meet the diversified clinical diagnosis and treatment needs of precision, efficiency, safety, and controllability. Summary of the invention

[0005] The purpose of the present invention is to design a new type of laser system used in medical lasers, so as to achieve the output of multiple lasers of different wavelengths individually, alternately or simultaneously through a medical laser device, and further optimize the laser structure, simplify the operation of medical personnel in clinical treatment, and realize accurate, efficient, safe and controllable multimodal laser diagnosis and treatment.

[0006] In order to achieve the above-mentioned object, the first aspect of the present invention provides a multi-core hybrid laser system, including a main control module, a plurality of optical modules, a laser alignment coupling module, a temperature control system module and a universal optical fiber interface, wherein: The main control module is used to generate a control signal according to preset input parameters and send it to the corresponding optical module; Each of the optical modules corresponds to a laser of a specific wavelength, and the optical module generates laser in response to the corresponding control signal; The laser alignment coupling module includes a plurality of laser alignment coupling submodules, and the laser alignment coupling submodule includes an optical switch for receiving the laser generated by the corresponding optical module, and then adjusting the optical path of the laser through the optical switch so that the laser is output from the universal optical fiber interface; The temperature control system module is used to monitor the temperature of all the optical modules and adjust the temperature thereof.

[0007] The above multi-core hybrid laser system adjusts the optical paths of multiple lasers of different wavelengths through multiple optical switches, so that the laser can output several lasers of different wavelengths individually, alternately or simultaneously, and further enables several lasers of different wavelengths to be output simultaneously through the same laser output channel after beam combination, thus optimizing the laser output structure. This technology meets the needs of applying multiple lasers of different wavelengths in clinical medical treatment, as well as the needs of using lasers of other wavelengths for optical monitoring and pathological diagnosis of physiological indicators of lesion tissues while using lasers of different wavelengths for clinical treatment, and further enables medical staff to use laser medical equipment with the multi-core hybrid laser system as the core technical device, and only needs one optical fiber to perform clinical treatment using a combination of lasers of different wavelengths, while achieving multiple wavelength laser diagnosis and treatment, and simplifies the operation of medical staff when using laser medical equipment for clinical diagnosis and treatment.

[0008] It should also be noted that the optical switch is a reflector driven by a motor, which can adjust the laser light path vertically or 45 degrees to the left, and then adjust the therapeutic working lasers generated by several optical modules to an optical fiber channel output, forming a combined beam of lasers with different wavelength combinations for clinical treatment.

[0009] In a possible implementation, the plurality of optical modules can respectively generate therapeutic working lasers of several different wavelengths, such as 630 nm, 980 nm, 1470 nm and 1940 nm.

[0010] In a possible implementation, each of the laser alignment coupling submodules further includes a dedicated optical fiber interface, wherein: When the optical switch does not adjust the optical path of the laser, the laser is output from the dedicated optical fiber interface; When the optical switch performs optical path adjustment, the laser light is adjusted to one of the universal optical fiber interfaces, and a combined laser beam with different wavelength combinations is output from the universal optical fiber interface.

[0011] In this implementation, each optical module that outputs a laser of a specific wavelength is equipped with a dedicated optical fiber output interface, so that medical staff can have more flexible choices when using laser medical equipment with a multi-core hybrid laser system as the core technical device. Specifically, medical staff can not only connect a fiber optic device through a universal optical fiber interface to use lasers of multiple wavelengths alone, alternately or simultaneously, but also connect multiple fiber optic devices through a universal optical fiber interface and multiple dedicated optical fiber interfaces to use lasers of multiple wavelengths alone, alternately or simultaneously. Medical staff can flexibly change the use of laser medical equipment with a multi-core hybrid laser system as the core technical device according to the needs of actual clinical diagnosis and treatment, which increases the flexibility of the practical application of the present invention.

[0012] In a possible implementation, both the universal optical fiber interface and the dedicated optical fiber interface adopt the SMA905 optical fiber interface model.

[0013] In a possible implementation, the laser collimation coupling submodule also includes a collimation unit and a coupling unit, wherein: the collimation unit is used to output the laser generated by the corresponding optical module after beam shaping; the coupling unit focuses and couples the laser before the dedicated optical fiber interface and / or the universal optical fiber interface receives the laser.

[0014] In this implementation, the divergent laser beam emitted by the optical module is beam shaped into a parallel laser beam through a collimation unit, thereby reducing the diffusion of the laser beam during transmission and improving the laser beam quality; and the laser beam is precisely focused and coupled into the core of the optical fiber through a coupling unit, thereby improving the efficiency of the optical fiber interface in receiving the laser.

[0015] In a possible implementation, among several optical modules, one of the optical modules corresponds to a tunable laser, and the optical module also includes a demodulation unit, wherein: after the optical module generates the tunable laser in response to the control signal, the demodulation unit receives a reflected light signal from the dedicated optical fiber interface, and then demodulates the reflected light signal to obtain demodulation information and send it to the main control module; the main control module is also used to calculate physiological indicator data based on the demodulation information.

[0016] It should also be noted that the physiological index data include temperature and pressure physiological index data of the lesion tissue.

[0017] It should also be noted that the optical module corresponding to the tunable laser means that the optical module can adjust the wavelength of the output laser within a certain range, that is, it can output lasers in a certain wavelength range. Specifically, in this implementation, the tunable laser refers to a laser with a wavelength scanning range of 8-10nm (C band).

[0018] In this implementation, the optical fiber interface can receive the reflected light signal transmitted by the optical fiber; when the output tunable laser is irradiated on the physiological tissue of the patient to be monitored, a reflected light signal will be generated, and the reflected light signal is usually reflected back by the reflective surface of the sensor probe at the end of the optical fiber. The reflected light signal is demodulated and processed into the original information signal by the demodulation unit, and the main control module compares and calculates the optical path difference change of the demodulated information with the emitted tunable laser information, and obtains the physiological index data such as temperature and pressure of the patient's physiological tissue.

[0019] In a possible implementation, the laser alignment coupling submodule further includes an optical signal processing unit, wherein: the tunable laser is output from the dedicated optical fiber interface after being branched by the optical signal processing unit.

[0020] In this implementation, the tunable laser is divided into multiple light signals by the optical signal processing unit for beam splitting transmission, so that the optical fiber interface can be connected to different optical fiber sensor probes to monitor the physiological tissue status of different positions of the patient, further improving the accuracy of the calculation of the optical path difference change. The beam splitting transmission improves the optical path matching of the output laser to the optical fiber sensor probe, reduces the error of comparative calculation and analysis of the optical path difference change, and thus improves the accuracy of measurement and monitoring of physiological indicators such as temperature and pressure of the patient's physiological tissue.

[0021] In a possible implementation, among several optical modules, one of the optical modules corresponds to the Raman laser, and the optical module also includes a spectral signal acquisition unit, wherein: after the optical module generates the Raman laser in response to the control signal, the spectral signal acquisition unit receives the reflected Raman spectral signal from the dedicated optical fiber interface, and then sends the reflected Raman spectral signal to the main control module; the main control module is also used to calculate pathological indicator data based on the reflected Raman spectral signal.

[0022] Specifically, the pathological indicator data include pH physiological indicator data, which are used to perform Raman spectroscopy pathological diagnosis of lesion tissue at the molecular level, and then to identify lesion boundaries with high accuracy, assisting clinicians in performing precise surgical treatments such as zoning treatment of tissues with different degrees of lesions and different lesion ranges using lasers of different wavelengths.

[0023] It should also be noted that the optical module corresponding to Raman laser means that the optical module can generate and output Raman laser of a certain wavelength range through the Raman effect. Wherein, the Raman spectrum refers to Raman spectrum laser with a wavelength scanning range of 185-1100nm.

[0024] In this implementation, when the output Raman laser is irradiated to the patient's lesion area, the molecules in the lesion area will be excited to produce specific spectral signals due to the Raman scattering effect, which is called Raman light change. The Raman spectrum signal is reflected back into the optical fiber, received and processed into a digital signal by the spectrum signal acquisition unit, and transmitted back to the main control module for analysis and calculation. The main control module analyzes the Raman spectrum peak of each molecule and screens and classifies it to distinguish the Raman spectra of normal physiological tissues and diseased tissues, and then uses the existing Raman spectrum database to match and analyze the obtained spectral data to obtain pathological indicator data such as symptoms corresponding to the patient's lesion area.

[0025] In a possible implementation, the temperature control system module includes a temperature controller and a plurality of temperature control fans, wherein: The temperature controller is electrically connected to the main control module and is used to monitor the temperature of all the optical modules and adjust the temperature thereof.

[0026] The plurality of temperature-controlled fans are used to adjust the working environment temperature of the laser.

[0027] In this implementation, accurate calculation, real-time calculation and precise control of the operating temperature of each optical module in the laser system are achieved, keeping the operating temperature of the optical module from drifting and the laser output wavelength from changing, ensuring that its photoelectric conversion efficiency will not decrease, improving the operating stability of the laser system, and optimizing the laser performance.

[0028] In one possible implementation, the optical module also includes a temperature control submodule, which includes a cooling fan and a TEC thermoelectric cooler, wherein: the temperature controller is used to monitor the temperature of the optical module, and when the temperature of the optical module is abnormal, the cooling fan is driven to cool the optical module or the TEC thermoelectric cooler is driven to adjust the current of the optical module.

[0029] Specifically, the temperature controller is located in the temperature control system module, and is used to send temperature control adjustment instructions to the TEC thermoelectric coolers in the optical modules; at the same time, the temperature controller can obtain the working temperature of the optical module, and accurately calculate the amount of current passing through the optical module through the central processor, thereby realizing real-time monitoring of the optical module current and adjusting the heat transmitted by the corresponding TEC thermoelectric cooler according to the monitoring situation. When the working temperature of the optical module is abnormal, the temperature controller drives the cooling fan in the corresponding abnormal optical module to cool down the abnormal optical module; or drives the TEC thermoelectric cooler to adjust the current passing through the abnormal optical module.

[0030] In this implementation, the temperature of the optical module is accurately detected by the temperature controller, and the working environment temperature of the optical module is dynamically adjusted by the cooling fan and the TEC thermoelectric cooler, so as to ensure that the working environment temperature does not change, and the laser wavelength output by the optical module does not drift, so as to maintain the photoelectric conversion efficiency of the optical module and improve the stability of the operation of the multi-core hybrid laser system. Furthermore, the above technology realizes the precise monitoring and control of the current of each optical module of the laser, can accurately adjust the heat transmitted by the TEC thermoelectric cooler, ensure the stable operation of the optical module, ensure the performance optimization of the laser, and realize the efficient and stable generation of several different wavelength lasers with a wide spectral range, meeting the needs of more clinical diagnosis and treatment applications of laser medical equipment.

[0031] In a possible implementation, the main control module further includes a main power supply and a main control board, wherein: the main power supply is respectively connected to the main control board and all the optical modules to supply power to the main control module and all the optical modules.

[0032] In this implementation, different power-consuming modules are powered by a main power supply; when any module encounters an operational failure, the main power supply can cut off its power supply, thereby increasing the safety of the operation of the multi-core hybrid laser system.

[0033] In a possible implementation, the main control module further includes a display unit, wherein: the display unit is connected to the main control board and is used to display the physiological indicator data and / or the pathological indicator data.

[0034] In this implementation, the physiological indicator data and / or pathological indicator data obtained by the main control module are displayed in real time through the display unit, which is beneficial for medical staff to monitor the patient's condition in real time during the laser treatment process of clinical diagnosis and treatment, further improving the integration of laser treatment and diagnosis, and enabling laser medical equipment with a multi-core hybrid laser system as the core technology device to integrate physiological indicator data and pathological indicator data for high-accuracy lesion boundary identification, which helps to sample tissues with different degrees of lesions and different lesion ranges, and then use different wavelength lasers for zoned treatment.

[0035] In a possible implementation, the main control board and the main power supply form a main control module. In this implementation, the main power supply includes a power switch and an emergency button. The power switch is used to start or stop the main power supply to other modules, and the emergency button is used to urgently cut off the electrical connection between the main power supply and other modules when a system failure occurs, so as to urgently interrupt the main power supply to other modules. Further, the main control module includes two central processing units and several communication interfaces. The two central processing units can operate independently, and establish independent communication links with the several optical modules through the several communication interfaces, so as to form a running program for efficient and fast interaction. Specifically, while one central processing unit performs data calculation and processing on the laser parameters input to the main control board, the other central processing unit can control the laser to operate autonomously. Through this implementation, the operating efficiency and intelligent management level of the laser are maximized.

[0036] A multi-core hybrid laser system provided by the present invention has at least the following advantages compared with the prior art: The multi-core hybrid laser system used in the above-mentioned medical laser generates several lasers of different wavelengths through several optical modules, and then adjusts the optical paths of several lasers of different wavelengths through several optical switches, so that lasers of different wavelengths can be output individually, alternately or simultaneously through several dedicated optical fiber interfaces or a universal optical fiber interface, which meets the needs of using different wavelengths of lasers for surgical treatment, physiological index monitoring and pathological diagnosis for different types of diseases in clinical medicine, as well as using different wavelengths of lasers for zoning treatment of tissues with different degrees of lesions and different lesion ranges, making laser medical equipment applicable to a wider range of surgical types, with a higher degree of integrated diagnosis and treatment, more significant surgical efficacy and safer surgical procedures.

[0037] On the one hand, the present invention further enhances the control and operation capabilities of multi-core hybrid lasers with complex structural types, such as information interaction, data calculation, intelligent analysis, and autonomous adjustment, so that the operation speed of the laser is faster, the operation efficiency is higher, and the interaction capability is stronger during the use of the laser, meeting the needs of intelligent control, autonomous operation, and efficient management of laser medical equipment.

[0038] On the other hand, the present invention enables lasers of different wavelengths to be outputted individually, alternately or simultaneously from a common optical fiber interface, thereby optimizing the laser output structure, so that when medical personnel use laser medical equipment with the multi-core hybrid laser system as the core technical device, they only need one optical fiber to perform clinical treatment using a combination of lasers of different wavelengths, thereby simplifying the operation of medical personnel using laser medical equipment for clinical diagnosis and treatment while realizing multiple wavelength laser diagnosis and treatment; Furthermore, the present invention also configures multiple dedicated fiber optic interfaces and one universal fiber optic interface for specific lasers of different wavelengths, so that medical personnel can also connect multiple fiber optic instruments through one universal fiber optic interface or multiple dedicated fiber optic interfaces, thereby outputting multiple lasers of different wavelengths individually, alternately or simultaneously, and then flexibly changing the use of laser medical equipment with a multi-core hybrid laser system as a core technical device according to the needs of actual clinical diagnosis and treatment, thereby increasing the flexibility of the practical application of the present invention; Furthermore, the present invention can also obtain physiological indicator data such as temperature and pressure of the patient's physiological tissue by receiving and processing reflected light signals, and can calculate pathological indicator data such as pH value based on the reflected Raman spectrum signal, which is beneficial for medical staff to monitor the patient's condition in real time during clinical diagnosis and laser treatment, improves the integration of laser treatment and monitoring diagnosis, and enables laser medical equipment with a multi-core hybrid laser system as the core technical device to integrate physiological indicator data and pathological indicator data for high-accuracy lesion boundary identification, which helps to sample tissues with different degrees of lesions and different lesion ranges, and then use different wavelengths of lasers for zoned treatment.
