Description

Technical Field

[0001] This application relates to the technical field of laser control in artificial intelligence, and particularly to a laser control method, device, equipment and medium for treating diseased blood vessels. Background Art

[0002] With the development of artificial intelligence technology, the photothermal treatment of lasers has been widely applied in various fields, such as intelligent security maintenance, intelligent machine cutting, health maintenance, etc.

[0003] In terms of health maintenance, the photothermal treatment of diseased blood vessels is usually carried out by making the diseased blood vessel tissue absorb the pulsed laser energy and be heated, so that it shrinks and coagulates.

[0004] At present, the commonly used laser for the photothermal treatment of diseased blood vessels is short-wavelength laser. When using short-wavelength laser with a large spot and high energy, although it can effectively treat diseased blood vessels, on the one hand, this commonly used short-wavelength laser is easily strongly absorbed by melanin, which will increase the risk of thermal damage to the treatment object with darker skin color, and its penetration ability is obviously insufficient for treating diseased blood vessels at deeper positions. On the other hand, it is also easy to have a certain impact on normal tissues. For example, telangiectasias are usually interspersed in normal tissues. When treating telangiectasias with this commonly used short-wavelength laser, normal tissues are also extremely likely to be damaged. Summary of the Invention

[0069] It should be understood that Figure 1 the numbers of the terminal device, the network, and the server in

[0070] Continue to refer to Figure 2 and Figure 3 , which shows a flowchart of an embodiment of the laser control method for processing diseased blood vessels according to the present application and a structural schematic diagram of an embodiment of the laser coagulation system. The laser control method for processing diseased blood vessels includes: step S201, step S202, step S203, step S204, and step S205.

[0071] In step S201, receive the to-be-processed vascular imaging data sent in real time by the scanning terminal.

[0072] In the embodiment of the present application, first, a high-energy laser with a laser wavelength of 595 nm is output by a laser generator (such as a laser wavelength generation module), and then the laser is split by a beam splitter. Then, one part of the split light beam, that is, part of the energy, is subjected to beam expansion and homogenization processing of the laser through a beam expansion processing module (such as a beam expansion and homogenization system) to obtain uniform spot illumination and reduce imaging noise. At the same time, one part of the split light beam, that is, part of the energy, is subjected to scattering imaging through a scanning terminal (such as a laser scattering imaging system) to obtain the scattering imaging data of blood vessels at each position (such as the thickness of blood vessels, skin characteristics, and position distribution characteristics at each position), that is, the to-be-processed vascular imaging data, so that the diseased blood vessels can be quickly and accurately identified through the to-be-processed vascular imaging data received in real time, thereby accurately obtaining the distribution characteristics (such as skin color characteristics and position depth) and blood vessel diameter (that is, the thickness of blood vessels) of the diseased blood vessels.

[0073] In step S202, obtain the distribution characteristics and blood vessel diameter of the target diseased blood vessels according to the to-be-processed vascular imaging data.

[0074] In the embodiment of the present application, after obtaining the to-be-processed vascular imaging data, intelligent processing such as image preprocessing and identification of target diseased blood vessels is performed on the to-be-processed vascular imaging data to quickly identify the current diseased tissue (that is, the target diseased blood vessels).

[0075] Furthermore, through target tracking technology, or target box positioning technology, or pose positioning technology, other methods can also be used to process the to-be-processed vascular imaging data to obtain the distribution characteristics and blood vessel diameter of the target diseased blood vessels, which are not specifically limited here, so as to obtain the blood vessel diameter (that is, the thickness) and position distribution at the diseased tissue subsequently, and upload the data to the upper computer, so that the upper computer can adjust the energy, pulse width, and spot size of the 595 nm laser in real time according to the blood vessel conditions at the obtained diseased positions to accurately control the required penetration power for processing diseased blood vessels at different positions. At the same time, based on the distribution characteristics, combined with the laser galvanometer scanning technology, the accurate movement direction and movement position of the laser are controlled to improve the processing accuracy of the diseased tissue and avoid the situation of incorrect processing of normal tissue.

[0076] In step S203, adjust the laser according to the blood vessel diameter of the target diseased blood vessels to obtain the adjusted focused spot size, laser energy, and laser pulse width.

[0077] In the embodiments of the present application, first, the split light source is expanded, specifically, the split light source can be expanded by a laser beam expander module (such as a beam expander and homogenizer system) to obtain an expanded light source, that is, a uniform spot illumination can be obtained, reducing imaging noise.

[0078] Further, the host computer can issue instructions to the laser generation module and the beam focal depth adjustment module according to the blood vessel diameter (i.e., the thickness of the diseased blood vessel), so that the beam focal depth adjustment module can adjust the focal depth of the expanded light source according to the proportional relationship between the blood vessel diameter and the focused spot size (such as the ratio between the blood vessel diameter and the focused spot size is 1:1.2) to obtain an adjusted focused spot size. For example, the focused spot size of the 595nm laser is slightly larger than the diameter of the blood vessel (about 1.2 times). Then, the laser generation module calculates the peak energy and pulse width according to the proportional relationship between the focused spot size, the laser energy, and the laser pulse width (such as a direct proportional relationship, that is, thick blood vessels correspond to high-energy, wide-pulse, large-size spot lasers, and thin blood vessels correspond to low-energy, narrow-pulse, small-size spot lasers), and adjusts the peak energy and pulse width of the laser according to the calculation results to obtain adjusted laser energy and laser pulse width, so as to accurately control the required penetration power for treating diseased blood vessels at different positions, effectively avoiding the situation of insufficient penetration. At the same time, it can also avoid the situation where when the 595nm pulse width is only 100μs, it is far lower than the thermal relaxation time of the blood vessel, and avoid the situation where when the required peak power is very high (up to 3000W), the high peak power is likely to cause blood vessel rupture and skin tissue purpura.

[0079] In step S204, according to the distribution characteristics of the target diseased blood vessel, the moving direction and moving position of the laser are determined.

[0080] In the embodiments of the present application, after obtaining the distribution characteristics of the target diseased blood vessel, the distribution characteristics of the target diseased blood vessel can be processed by target tracking technology, or target box positioning technology, or pose positioning technology, or other methods can also be used to obtain the moving direction and moving position of the laser that needs to rotate or translate with the flow of the target diseased blood vessel. There is no specific limitation here, so as to realize precise control of the rotation or translation of the laser with the flow of the target diseased blood vessel based on the moving direction and moving position of the laser in combination with the galvanometer scanning technology of the laser (that is, realize precise control of laser irradiation), so as to improve the treatment accuracy of diseased tissues and avoid the situation of incorrect treatment of normal tissues.

[0081] In step S205, the laser whose focused spot size, laser energy, and laser pulse width have been adjusted is used to coagulate the target diseased blood vessel according to the moving direction and moving position of the laser through the galvanometer scanning technology of the laser.

[0082] In the embodiment of the present application, the laser whose focal spot size, laser energy, and laser pulse width have been adjusted can be accurately rotated or translated according to the moving direction and moving position of the laser by using the galvanometer scanning technology of the galvanometer scanning module of the laser, such as controlling the 595nm laser beam to flow along the target diseased blood vessel (that is, realizing precise control of laser irradiation), so as to perform thermal coagulation treatment on the target diseased blood vessel (specifically, the laser can be output point by point at a certain interval to perform thermal coagulation on the blood vessel), so as to improve the treatment accuracy rate of the diseased tissue and avoid the situation of misprocessing of normal tissue.

[0083] It can be understood that after the thermal coagulation treatment is performed on the current position of the target diseased blood vessel, when the galvanometer scanning module scans to the next position of the target diseased blood vessel, the energy, pulse width, and spot size of the laser can be adjusted again according to the blood vessel diameter corresponding to the next position (that is, the thickness of the blood vessel), and thermal coagulation is performed, and this cycle is repeated to complete the coagulation treatment of the entire target diseased blood vessel.

[0084] In the embodiment of the present application, a laser control method for treating diseased blood vessels is provided, including: receiving the imaging data of the blood vessel to be treated sent by the scanning terminal in real time; obtaining the distribution characteristics and blood vessel diameter of the target diseased blood vessel according to the imaging data of the blood vessel to be treated; adjusting the data of the laser according to the blood vessel diameter of the target diseased blood vessel to obtain the adjusted focal spot size, laser energy, and laser pulse width; determining the moving direction and moving position of the laser according to the distribution characteristics of the target diseased blood vessel; and performing coagulation treatment on the target diseased blood vessel with the laser whose focal spot size, laser energy, and laser pulse width have been adjusted according to the moving direction and moving position of the laser by using the galvanometer scanning technology. Compared with the prior art, the present application can quickly and accurately identify the distribution characteristics and blood vessel diameter of the target diseased blood vessel through the laser imaging method, and can not only accurately adjust and control the spot, energy, and pulse width of the laser based on the blood vessel diameter to meet the precise control of the required penetration power for treating diseased blood vessels at different positions, but also realize the control of the precise moving direction and moving position of the laser based on the distribution characteristics combined with the galvanometer scanning technology, so as to improve the treatment accuracy rate of the diseased tissue and avoid the situation of misprocessing of normal tissue.

[0085] In some optional implementation manners of the embodiment of the present application, before the step S201 of receiving the imaging data of the blood vessel to be treated sent by the scanning terminal in real time, the method further includes the following steps:

[0086] The laser is split into N split light sources, so that the scanning terminal performs real-time scanning imaging on the blood vessel to be treated based on M split light sources, where N is an integer greater than 1, and M is an integer less than N.

[0087] In the embodiments of the present application, a laser generator (such as a laser generation module) can output a laser with a wide pulse and high energy at 595 nm. Among them, the 595-nm laser can be generated by frequency doubling of a 1090-nm laser and a 1319-nm laser, or can be generated by self-doubling of ytterbium (Yb) ions. In addition, the specific parameters of the 595-nm laser include a peak power range of 1-20 W, a pulse width of 1-100 ms, and a frequency of 1-5 Hz, etc.

[0088] Further, when the laser generator (such as a laser generation module) outputs a laser with a wide pulse and high energy at 595 nm, the laser is split to obtain N split light sources, so that in the subsequent process, N split light beams, that is, a part of the energy, can be imaged through a scanning terminal (such as a laser scattering imaging system) to obtain imaging data of blood vessels at each position (such as the thickness of blood vessels, skin characteristics, and position distribution characteristics at each position), that is, the blood vessel imaging data to be processed, so that in the subsequent process, the diseased blood vessels can be quickly and accurately identified through the received blood vessel imaging data to be processed in real time (that is, the real-time detection of diseased blood vessels) is realized, so as to accurately obtain the distribution characteristics of diseased blood vessels (such as skin color characteristics and position depth, etc.) and the blood vessel diameter (that is, the thickness of blood vessels).

[0089] In some optional implementation manners of the embodiments of the present application, the above step S203 adjusts the data of the laser according to the blood vessel diameter of the target diseased blood vessel to obtain the adjusted focused spot size, laser energy, and laser pulse width, which specifically includes the following steps:

[0090] Expand the K split light sources to obtain expanded light sources, where K is an integer less than N;

[0091] In the embodiments of the present application, first, the K split light sources are expanded. Specifically, the split light sources can be expanded through a laser beam expander (such as a beam expander and homogenizer system) to obtain expanded light sources, that is, a uniform spot illumination can be obtained to reduce imaging noise.

[0092] Adjust the depth of focus of the expanded light source according to the proportional relationship between the blood vessel diameter and the focused spot size to obtain the adjusted focused spot size.

[0093] In the embodiment of the present application, the host computer can issue an instruction to the beam focal depth adjustment module according to the blood vessel diameter (i.e., the thickness of the diseased blood vessel), so that the beam focal depth adjustment module can adjust the focal depth of the beam expander light source according to the proportional relationship between the blood vessel diameter and the focused spot size (such as the ratio between the blood vessel diameter and the focused spot size is 1:1.2), so as to obtain the adjusted focused spot size. For example, the focused spot size of the 595nm laser is slightly larger than the diameter of the blood vessel (about 1.2 times), ensuring that the entire cross-section of the blood vessel is subjected to the thermal action of light.

[0094] According to the proportional relationship between the focused spot size and the laser energy and the laser pulse width, the peak energy and the pulse width of the laser are adjusted to obtain the adjusted laser energy and laser pulse width.

[0095] In the embodiment of the present application, the host computer can issue an instruction to the laser generation module according to the blood vessel diameter (i.e., the thickness of the diseased blood vessel), so that the laser generation module calculates the peak energy and the pulse width according to the proportional relationship between the focused spot size and the laser energy and the laser pulse width (such as a direct proportional relationship, that is, a thick blood vessel corresponds to a laser with high energy, wide pulse, and large spot size, and a thin blood vessel corresponds to a laser with low energy, narrow pulse, and small spot size), so as to obtain the calculation result.

[0096] It can be understood that the laser generator (such as the laser generation module) can adjust the energy and pulse width of the 595nm laser (i.e., the laser action time on the tissue). Among them, the energy E (unit: J) of the 595nm laser is proportional to the focused spot area of the 595nm laser, that is, proportional to the square of the diameter R (unit: μm) of the focused spot of the 595nm laser, so as to ensure that the optical power density of the focused spot of the 595nm laser remains unchanged. The specific calculation formula can be expressed as follows: E = 2.5×10^(-12)πR^4; among them, the pulse width T (unit: ms) of the 595nm laser is proportional to the focused spot area of the 595nm laser, that is, proportional to the square of the diameter R (unit: μm) of the focused spot of the 595nm laser. The specific calculation formula can be expressed as follows: T = 5×10^(-4)R^2).

[0097] Further, after obtaining the calculation result according to the above calculation formula, the peak energy and pulse width of the laser can be adjusted according to the calculation result to obtain the adjusted laser energy and laser pulse width, so as to accurately control the required penetration power for treating diseased blood vessels at different positions, effectively avoiding the situation of insufficient penetration power. In addition, on the one hand, it can avoid the situation where the 595nm pulse width is only 100μs, which is far lower than the thermal relaxation time of blood vessels, and avoid the situation where when the required peak power is very high (up to 3000W), the high peak power is likely to cause blood vessel rupture and lead to the generation of skin tissue purpura. On the other hand, the optimized 595nm laser peak power is only a small part of the power of the traditional laser (such as 1 / 100), greatly reducing the development difficulty of the laser and the large-energy power supply, and also reducing the cost of the equipment.

[0098] In some alternative implementation manners of the embodiment of the present application, the above step S202 obtains the distribution characteristics and blood vessel diameter of the target diseased blood vessel according to the blood vessel imaging data to be processed, and specifically includes the following steps:

[0099] Perform image preprocessing and identification of the target diseased blood vessel on the blood vessel imaging data to be processed to obtain the distribution characteristics and blood vessel diameter of the target diseased blood vessel.

[0100] After obtaining the blood vessel imaging data to be processed, perform intelligent processing of image preprocessing (such as image cropping, scaling, denoising, enhancement, normalization, etc.) and identification of the target diseased blood vessel (such as feature extraction, feature identification, feature matching, and model identification, etc.) on the blood vessel imaging data to be processed, and quickly identify the current diseased tissue (i.e., the target diseased blood vessel).

[0101] Further, through target tracking technology, target box positioning technology, or pose positioning technology, other methods can also be used to process the blood vessel imaging data to be processed to obtain the distribution characteristics and blood vessel diameter of the target diseased blood vessel. There is no specific limitation here, so as to obtain the blood vessel diameter (i.e., the thickness of the blood vessel) and position distribution at the diseased tissue subsequently, and upload the data to the host computer, so that the host computer can adjust the energy, pulse width, and spot size of the 595nm laser in real time according to the blood vessel conditions at the obtained diseased positions, so as to accurately control the required penetration power for treating diseased blood vessels at different positions. At the same time, based on the distribution characteristics and combined with the laser galvanometer scanning technology, the accurate moving direction and moving position of the laser are controlled to improve the processing accuracy of the diseased tissue and avoid the situation of incorrect processing of normal tissue.

[0102] In some alternative implementation manners of the embodiments of the present application, before the step of adjusting the laser data according to the blood vessel diameter of the target diseased blood vessel in step S203 to obtain the adjusted focused spot size, laser energy, and laser pulse width, the method further includes the following steps:

[0103] Determine the laser wavelength of the laser according to the distribution characteristics of the target diseased blood vessel.

[0104] In the embodiments of the present application, in order to better process the diseased blood vessels in the state of deep surface layer and deep skin color to achieve better penetration, the laser wavelengths usually used in this embodiment are all 595 nm. For the diseased blood vessels in the state of shallow surface layer or light skin color, better laser treatment effects can still be achieved by using the absorption peaks of other wavelengths of hemoglobin, such as laser wavelengths of 532 nm, 545 nm, and 577 nm, etc. Therefore, the appropriate laser wavelength can be selected according to the distribution characteristics of the target diseased blood vessel, that is, according to the diseased blood vessels distributed at different surface layer positions or different skin color states, to achieve precise control of laser irradiation.

[0105] In some alternative implementation manners of the embodiments of the present application, the distribution characteristics of the target diseased blood vessel include position distribution characteristics; the above-mentioned determining the laser wavelength of the laser according to the distribution characteristics of the target diseased blood vessel specifically includes the following steps:

[0106] When the position distribution characteristic is a non-shallow surface layer position characteristic, determine the laser wavelength of the laser as the first laser wavelength;

[0107] In the embodiments of the present application, when the position distribution characteristic is a non-shallow surface layer position characteristic, that is, when it is necessary to process the diseased blood vessels in the state of non-shallow surface layer position (such as deep surface layer), a laser with a longer wavelength can be selected, that is, determine the laser wavelength of the laser as the first laser wavelength. For example, the first laser wavelength is 595 nm, so as to reduce the situation where the laser is absorbed by melanin and thus achieve better penetration.

[0108] When the position distribution characteristic is a shallow surface layer position characteristic, determine the laser wavelength of the laser as the second laser wavelength, where the second laser wavelength is less than the first laser wavelength.

[0109] In the embodiments of the present application, when the position distribution characteristic is a shallow surface layer position characteristic, that is, when it is necessary to process the diseased blood vessels in the state of shallow surface layer position (such as shallow surface layer), a laser with a shorter wavelength can be selected, that is, determine the laser wavelength of the laser as the second laser wavelength. For example, the second laser wavelength is 532 nm, 545 nm, or 577 nm, etc., and precise control of laser irradiation can be achieved by selecting the appropriate laser wavelength.

[0110] In some alternative implementation manners of the embodiments of the present application, the distribution feature of the target diseased blood vessel includes the skin color distribution feature; the specific steps of determining the laser wavelength of the laser according to the distribution feature of the target diseased blood vessel are as follows:

[0111] When the skin color distribution feature is a non-light skin color feature, the laser wavelength of the laser is determined as the first laser wavelength.

[0112] In the embodiments of the present application, when the position distribution feature is a non-light skin color feature, that is, when it is necessary to treat the diseased blood vessels in the state of treating non-light skin color (such as dark skin color), a laser with a longer wavelength can be selected, that is, the laser wavelength of the laser is determined as the first laser wavelength. For example, the first laser wavelength is 595 nm, so as to reduce the situation where the laser is absorbed by melanin, thereby achieving better penetration.

[0113] When the skin color distribution feature is a light skin color feature, the laser wavelength of the laser is determined as the second laser wavelength, where the second laser wavelength is less than the first laser wavelength.

[0114] In the embodiments of the present application, when the position distribution feature is a light skin color feature, that is, when it is necessary to treat the diseased blood vessels in the state of treating light skin color (such as light skin color), a laser with a shorter wavelength can be selected, that is, the laser wavelength of the laser is determined as the second laser wavelength. For example, the second laser wavelength is 532 nm, 545 nm or 577 nm, etc. By selecting an appropriate laser wavelength, precise control of laser irradiation can be achieved.
