Description

Technical Field

[0001] The present invention belongs to the field of skin laser beauty, and in particular relates to a beauty method and equipment based on ultrashort pulse laser. Background Art

[0002] Fractional laser skin rejuvenation currently available on the market utilizes the principle of focal photothermal effects. Lasers with strong absorption in water are used, using specialized techniques to create multiple, fine beams of uniform diameter. When these beams reach a certain energy level, they penetrate the epidermis and enter the dermis. Due to the strong absorption of water in skin tissue, the tissue along the path of the laser beam absorbs the laser energy and generates heat, causing columnar thermal denaturation or perforation along the beam's path. This damage triggers the body's wound healing mechanism, remodeling and rebuilding the epidermis and dermis. The lasers currently used in this skin rejuvenation technique are categorized as vaporizing fractional lasers and non-vaporizing fractional lasers. The former uses a highly absorptive laser to create a vaporization effect in the skin, generating actual columnar pores, while the latter only creates columnar thermal denaturation zones without actual pores. Since the vaporization fractional laser treatment method causes greater damage to the skin, including epidermal necrosis and shedding, carbonization of dermal pores, protein denaturation, etc., it stimulates the dermis more strongly and activates a more obvious skin repair mechanism. It is the preferred treatment option in clinical practice. The mainstream vaporization fractional laser beauty equipment on the market currently uses carbon dioxide lasers (wavelength 10.6um), erbium lasers (wavelength 2.94um), and yttrium scandium gallium garnet lasers (2.79um). These wavelengths are near the absorption peak of water molecules and rely on photothermal effects to form vaporization damage to skin tissue. Imported picosecond and ultra-picosecond cosmetic devices utilize 1064nm or 755nm laser beams with pulse widths of hundreds of picoseconds, creating localized fractional photodamage with a "honeycomb" pattern of multiple light spots. However, their mechanism of action relies on extremely high single-pulse energy, accompanied by heat absorption, to create a lesion in the skin. This is not completely athermal photodamage, and clinically, this can cause cosmetic side effects such as redness, swelling, blisters, and hyperpigmentation. These side effects are also caused by excessive water absorption of the light energy, which generates thermal damage. The need to create a sufficiently intense lesion within the skin while limiting incidental thermal damage is a difficult dilemma for traditional fractional laser treatments currently available.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] The present invention designs a cosmetic method and device based on ultrashort pulse lasers, which utilizes a skin rejuvenation technology that utilizes the photoblasting effect of ultrashort pulse lasers in water-rich human skin tissue. The implementation of this technology includes the introduction of an ultrashort pulse laser, as well as the collimation and focusing of its output beam. Simultaneously, a collection device (ultrasonic imaging device) is used to observe in real time the position and size of the cavities formed by the blasting points of the ultrashort pulse laser in the skin. This feedback is fed back to the laser control system to automatically operate the laser beam converging device, stimulating the photoblasts one by one in the skin to form tiny columnar channels, stimulating the dermis to initiate the repair mechanism, and promoting the rapid regeneration of collagen fibers. Specifically:

[0051] On the one hand, the present application provides a cosmetic method based on ultrashort pulse laser. The light source of the ultrashort pulse laser is a near-infrared laser with a pulse width of 1ps, a central wavelength of 1030nm, a repetition frequency of 1kHz, and a single pulse energy of 30uJ. The signal irradiated on the skin tissue is a 10×10 micro beam dot matrix, and the energy of each laser beam is consistent (about 3uJ). These dot matrix laser beams are converged on the same focal plane through the focusing lens. This focal plane is the laser focusing blasting dot matrix surface under the skin. By appropriately extending the irradiation time of the ultrashort pulse and reducing the focal length of the focusing lens, the lack of single pulse energy can be compensated. Among them, cosmetic methods such as Figure 1 Shown, including,

[0052] Step S110: Acquire current basic feature information; basic feature information can be understood as information corresponding to the cavity formed by the laser signal acting on the skin tissue, such as size information and depth information corresponding to the cavity. Further, specifically including:

[0053] Step S1101, in a state where no characteristic area is formed on the target body, the current characteristic basic information is formed according to the initial value; wherein the target body can be understood as the skin tissue to be treated. When the skin tissue to be treated is subjected to laser treatment for the first time, the skin tissue to be treated has not yet formed a characteristic area (i.e., a cavity area). At this time, the current characteristic basic information is formed with the initial value, and the initial value can be any point in the current skin tissue area to be treated as the initial value. A special point of the skin tissue to be treated can also be used as the initial value, for example, when treating spots, a special point such as the boundary of the spot or the center of the spot. For example, when treating acne, a special point such as the boundary of the acne or the center of the acne. The setting point of the initial value position is not specifically limited here and can be determined according to actual use. The coordinate value of the initial value can be defined as (0.0.0).

[0054] It should be noted that the characteristic region is an objectively existing hole, and the characteristic basic information is the data information presented by the hole region.

[0055] Step S1102: Read the current basic characteristic information when a characteristic region is formed on the target. When a characteristic region is formed on the target, it can be determined that the skin tissue to be treated has undergone at least one laser treatment. A cavity formed by laser treatment is a characteristic region. Illustratively, when a cavity is present in the skin tissue to be treated, the location and depth information of the cavity are read, and the current basic characteristic information is generated based on the location and depth information.

[0056] Step S120: forming the next first characteristic information data based on the current characteristic basic information combined with the basic information of the ultrashort pulse laser; wherein the next first characteristic information data matches the next cavity position, and the basic information of the current characteristic information at least includes the current first characteristic information data and the current second characteristic information data; schematically, the current first characteristic information data can be understood as the cavity position information, and the current second characteristic information data can be understood as the cavity depth information. Specifically,

[0057] Step S1201: Acquire first characteristic information of the ultrashort pulse laser, and form the first data of the next characteristic information according to the first data of the current characteristic information and the first characteristic information; the first characteristic information of the ultrashort pulse laser can be understood as beam size information of the ultrashort pulse laser, and the first data of the next characteristic information can be understood as position information of the next cavity. Schematically, the first data of the next characteristic information is formed according to the first data of the current characteristic information and the first characteristic information as follows:

[0058] X1=X0+a;

[0059] X1 is the first data of the next characteristic information;

[0060] X0 is the first data of the current feature information;

[0061] a is the first characteristic information of the ultrashort pulse laser.

[0062] It should be noted that the first data of the current characteristic information can be the X-axis coordinate data of the current hole, or the Y-axis coordinate data of the current hole; when the first data of the current characteristic information is the X-axis coordinate data of the current hole, the first data of the next characteristic information is also the X-axis coordinate data of the next hole, and the point-to-point connected channel formed by the sequential circular connection is parallel to the X-axis; similarly, when the first data of the current characteristic information is the Y-axis coordinate data of the current hole, the first data of the next characteristic information is also the Y-axis coordinate data of the next hole, and the point-to-point connected channel formed by the sequential circular connection is parallel to the Y-axis.

[0063] Step S1202: Acquire the second characteristic information of the ultrashort pulse laser, and form the next characteristic information second data according to the current characteristic information second data and the second characteristic information. The next characteristic information second data can be understood as the depth information of the next cavity. Schematically, the next characteristic information second data is formed according to the current characteristic information second data and the second characteristic information as follows:

[0064] Y1=Y0-b;

[0065] Y1 is the second data of the next characteristic information;

[0066] Y0 is the second data of the current feature information;

[0067] b is the second characteristic information of the ultrashort pulse laser. The second characteristic information of the ultrashort pulse laser can be understood as the beam power information of the ultrashort pulse laser, and the beam power information matches the depth information of the cavity formed by the ultrashort pulse laser.

[0068] For example, if the current cavity is 500 μm deep into the skin and the laser depth dimension is 60 μm, then the next cavity will be 440 μm deep into the skin. Similarly, the cavity point generated by the laser will gradually move upwards each time.

[0069] Step S1203: Generating the next characteristic information data based on the first characteristic information data and the second characteristic information data. The first characteristic information data is used to ensure that the cavity formed by the next laser is connected to the boundary of the current cavity (which can also be understood as the formed laser points are interconnected), and the second characteristic information data is used to ensure that the cavity formed by the next laser is located above the boundary of the current cavity (which can also be understood as the depth direction of the formed laser points gradually decreases).

[0070] Step S130, forming a control instruction that matches the next characteristic information data based on the next characteristic information data; schematically, the control instruction is used to act on a mobile device, and the hole depth is adjusted by adjusting the distance between the mobile device and the skin tissue, and the hole position is adjusted by adjusting the relative position between the mobile device and the current hole.

[0071] Step S140 : outputting a laser signal matching the next feature information data to form a target feature image when the control instruction is executed.

[0072] The treatment or cosmetic principles of the above technical solution are:

[0073] like Figure 2 As shown, the ultrashort pulse laser light source used in this invention is a near-infrared laser with a pulse width of 1ps, a central wavelength of 1030nm, a repetition rate of 1kHz, and a single pulse energy of 30uJ. The laser beam passes through a focusing lens and converges onto the skin tissue to be treated. After scattering and absorption by the skin tissue, approximately 22uJ of laser energy still converges at the lens focal point. The spot diameter at the focal point is tens of microns, resulting in an instantaneous optical power density of GW / cm 2, sufficient to stimulate photoionization in water-rich tissue, further triggering inverse bremsstrahlung and avalanche ionization, ultimately forming a plasma and a blasting effect. Intense mechanical waves create cavities within the skin at the focal point of the light. For skin tissue, cavities caused by this external energy represent tissue damage, triggering the skin's repair mechanisms. The larger the area of ​​photodamage, the more pronounced the stimulation to the skin, and the more strongly the repair mechanisms are stimulated. To create larger cavities and inflict extensive external damage to stimulate the skin, continuous cavities must be produced. Using the above-described embodiment, after a cavity is formed, the laser beam's focal point is moved upward, generating another photoblasting effect in the normal tissue above the cavity, creating another cavity. The cavities are connected but not overlapping. After each laser operation, information about the formed cavities is acquired, and the location of the next blasting point (i.e., the next cavity position) is determined based on the current cavity information. The depth information of the next blasting point (i.e., the next cavity depth) is calculated based on the current cavity depth information. This process repeats, allowing each cavity to connect to the previous one. The location of the previous cavity is then detected and calculated, and points are placed one by one along the beam's propagation direction, connecting the boundaries of each point. Ultimately, a columnar cavity is formed, similar to the columnar channels created by fractional laser photothermal therapy. These tiny channels, formed entirely by photomechanical blasting, stimulate the skin's repair mechanism in the dermis without causing microscopic burns or carbonization, significantly reducing treatment side effects.

[0074] This skin rejuvenation technology, based on the photoblasting effect of ultrashort pulse laser in water-rich human skin tissue, introduces an ultrashort pulse laser, collimates and focuses its output beam, and simultaneously observes in real time the position and size of the cavity formed by the blasting point of the ultrashort pulse laser in the skin to form control instructions that match the position and size of the next cavity. Similarly, photoblasts are stimulated one by one in the skin to form tiny columnar channels, stimulating the dermis tissue to initiate the repair mechanism and promote the rapid regeneration of collagen fibers.

[0075] As a further preferred embodiment, the above-mentioned cosmetic method based on ultrashort pulse laser, wherein: further comprising,

[0076] Step S150: Determine whether the target characteristic image matches predetermined characteristic pattern information. Predetermined characteristic pattern information can be understood as target treatment image information that matches the skin tissue being treated. This predetermined characteristic pattern information is determined based on actual application and is not limited here. This step is intended to determine whether the formed cavity image is consistent with the expected cavity image.

[0077] Step S160 : when the target feature image does not match the predetermined feature graphic information, forming current feature basic information according to the next feature information data; that is, repeating steps S110 - S150 .

[0078] Step S170 , when the target feature image matches the predetermined feature pattern information, stop outputting the laser signal.

[0079] Example 2

[0080] On the other hand, Figure 3 As shown, the present invention provides a beauty device based on ultrashort pulse laser, which includes:

[0081] The acquisition unit is used to acquire current state information of the target area and form current feature basic information based on the current state information; further, the acquisition unit can be formed by an ultrasonic acquisition device and an ultrasonic image processor, and at least one ultrasonic acquisition device is arranged above the ultrashort pulse laser transmission target area to obtain current cavity information through the ultrasonic acquisition device.

[0082] Schematically, two ultrasonic acquisition devices are provided. These can be dual-channel ultrasonic detectors, which serve as tools for capturing cavity location information. They receive ultrasonic waves from two different directions during the blasting process. An ultrasonic image processor calculates the source of the sound waves based on the position of the sound wave field, thereby locating the blast point, and thus the location of the cavity.

[0083] A control unit is used to form next characteristic information data based on the current characteristic basic information combined with the basic information of the ultrashort pulse laser; and form a control instruction matching the next characteristic information data based on the next characteristic information data; further, the control instruction includes at least a displacement control instruction and a laser control instruction.

[0084] An action unit is used to execute an action matching the control instruction under the action of the control instruction. The action unit includes at least a spatial light modulator, a displacement device, and a focusing device, specifically:

[0085] The spatial light modulator is used to modulate the basic light signal output by the laser to form a target laser signal under the action of the laser control command. Furthermore, the spatial light modulator can be formed by a silicon-based liquid crystal spatial light modulator. The spatial light modulator is placed before the focusing device, which can diffract the basic light signal according to the array of lattice lasers to form the incident ultrashort pulse laser beam (target laser signal). When a 1.5mm diameter ultrashort pulse laser beam with an energy of 300uJ (basic laser signal) is perpendicularly incident on the silicon-based liquid crystal spatial light modulator, the modulator driver controls the diffraction effect under the action of the laser control command to generate a 10×10 tiny beam lattice, and the energy of each laser beam is consistent (approximately 3uJ).

[0086] a displacement device, which adjusts the position device under the action of the displacement control instruction so that the target laser signal is transmitted along a predetermined direction and a predetermined blasting depth;

[0087] The focusing device receives the laser signal and focuses it to form a target beam, which is then transmitted to the target area. Specifically, these 10×10 micro-beams are converged onto the same focal plane through a focusing lens. This focal plane is the subcutaneous laser focused blasting array plane (i.e., the target area).

[0088] As a further preferred embodiment, the above-mentioned beauty device based on ultrashort pulse laser, wherein: the control unit further includes:

[0089] Determine whether the target feature image matches the predetermined feature graphic information; when the target feature image does not match the predetermined feature graphic information, form current feature basic information based on the next feature information data; or, when the target feature image matches the predetermined feature graphic information, generate a laser instruction output to control the laser to stop working.

[0090] List a specific application:

[0091] In the initial application, with the user setting the initial position, the device receives the basic optical signal output by the laser and modulates it to form a target laser signal under the control of the laser control command. Furthermore, the spatial light modulator can be formed by a liquid crystal on silicon spatial light modulator. Placed before the focusing device, the spatial light modulator can diffract the basic optical signal into an array of laser lattices to form an incident ultrashort pulse laser beam (target laser signal). When a 1.5mm diameter ultrashort pulse laser beam (basic laser signal) with an energy of 300uJ is perpendicularly incident on the liquid crystal on silicon spatial light modulator, the modulator driver controls the diffraction effect under the control of the laser control command to generate a 10×10 array of tiny beams, with each beam having a consistent energy (approximately 3uJ). A displacement device adjusts the positioning device under the control of the displacement control command so that the target laser signal is transmitted along a predetermined direction and at a predetermined depth. A focusing device receives the laser signal and focuses it to form a target beam, which is then transmitted to the target area to cause the blast. Specifically, these 10×10 tiny beam dot matrix laser beams are converged onto the same focal plane through a focusing lens. This focal plane is the subcutaneous laser focused blasting dot matrix plane (i.e., the target area). A dual-channel ultrasonic detector is used as a tool to capture cavity position information, receiving ultrasonic waves from the blasting process from two different directions. The ultrasonic image processor calculates the source point of the sound wave based on the position of the sound wave field, thereby locating the position of the blasting point, that is, the position of the cavity. It is used to form the next feature information data based on the current feature basic information combined with the basic information of the ultrashort pulse laser; based on the next feature information data, a displacement control instruction and a laser control instruction that match the next feature information data are formed; a displacement device, under the action of the displacement control instruction, adjusts the position device so that the target laser signal is transmitted along a predetermined direction and a predetermined blasting depth; and continues to expose the target area until the treatment is completed.

[0092] The technical effect obtained after implementation of the above-mentioned beauty device based on ultrashort pulse laser is the same as the technical effect obtained in Example 1, and will not be described in detail here.
