Description

Technical Field

[0001] The present disclosure relates to an ultrasonic generator. More specifically, the present disclosure relates to an ultrasonic generator that can selectively provide an increase or decrease in the subcutaneous fat layer or an improvement in elasticity by the applied ultrasonic energy when the ultrasonic energy is applied.

Background Art

[0002] Ultrasonic waves mean waves having a frequency of 20 kHz or higher, have the property of transmitting through water, and are widely used in the medical field such as ultrasonic diagnostic devices and ultrasonic treatment devices.

[0003] The utilization of ultrasonic waves in the medical field is most typically represented by an ultrasonic imaging device that utilizes the properties of ultrasonic waves to transmit and reflect. For example, there is a device that visualizes the time and intensity of ultrasonic waves transmitted through the human body and reflected while passing through each organ to obtain a cross-sectional image of the human body.

[0004] In addition, there is a device that uses the heat generated by high-intensity focused ultrasound (HIFU) to burn and remove specific subcutaneous tissues such as skin tumors, or to induce degeneration and regeneration of skin tissues to produce effects such as skin beautification or plastic surgery for improving wrinkles.

[0005] Currently, ultrasonic generators in the skin beauty market are used for lifting treatments by focusing ultrasonic energy on the SMAS layer of the skin, or for treatments that focus strong energy on the subcutaneous fat layer to destroy fat cells and reduce fat.

[0006] Such an ultrasonic generator focuses ultrasonic waves at a desired depth and can adjust the desired depth. It is used to transmit effective energy to a desired depth without damaging the epidermis.

[0007] As methods for transmitting energy with an ultrasonic generator, there are a dot method and a linear method. The dot method is the most widely used method. In this method, while the transducer repeatedly stops moving, energy is applied at the stopped positions to apply fixed energy in the form of one point or multiple points. The linear method is a method in which energy is continuously applied while the transducer moves at a constant speed over a specific distance, creating linear thermogenesis in the skin tissue.

[0008] The dot type is a classical method that is widely used in lifting. Since the linear type enables bulk heating, it has been effectively used for fat reduction.

[0009] However, when strongly applying ultrasonic energy with the dot type and the linear type, there is a risk of burning the epidermis, and inflammatory substances may be generated, causing problems in the dermis layer. This is due to excessive tissue coagulation.

[0010] In addition, when performing ultrasonic treatment with strong energy as in the conventional method in areas without a fat layer, problems such as further reduction of the fat layer often occur, or ultrasonic treatment may not be recommended for people with a thin fat layer.

[0011] Therefore, research is needed to find energy and methods that not only reduce fat in a desired area by ultrasonic waves but also increase elasticity and increase the fat layer.

[0022] Furthermore, the ultrasonic generator irradiates the ultrasonic waves to the skin layer and the fat layer in a frequency band of 2 MHz, 4 MHz, 5.5 MHz, 7 MHz, 10 MHz, 20 MHz up to 0.1 mm to 13 mm.

[0033] Hereinafter, with reference to the accompanying drawings, the working principle and embodiments of the present disclosure will be described.

[0034] First, High Intensity Focused Ultrasound (HIFU) technology is a latest thermal ablation treatment technique that utilizes the heat generated when high-intensity ultrasound is concentrated at a single point within the skin to burn specific subcutaneous tissues such as skin tumors. This is similar to the principle of gathering warm sunlight through a magnifying glass to start a fire. Since ultrasound easily passes through body tissues, HIFU treatment is performed in a perfect non-invasive manner without even a knife or a needle. That is, it is a treatment method of burning specific subcutaneous tissues such as tumors by simply bringing the skin of the patient's treatment site into close contact with the ultrasound generating surface. Moreover, currently HIFU treatment is also utilized for the treatment of uterine fibroids, bone metastasis cancer, prostate cancer, breast cancer, pancreatic cancer, liver cancer, kidney cancer, etc.

[0038] The server device is a server that communicates with external devices and processes information, and can include an application server, a computing server, a database server, a file server, a mail server, a proxy server, and a web server, etc.

[0039] The portable terminal is, for example, a wireless communication device that ensures portability and mobility, and includes various types of handheld-based wireless communication devices such as PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), WiBro (Wireless Broadband Internet) terminals, smart phones, etc., and wearable devices such as watches, rings, bracelets, anklets, necklaces, glasses, contact lenses, or head-mounted devices (HMDs).

[0040] The ultrasonic generator according to the present disclosure can control the ultrasonic generating unit so that the ultrasonic generating unit applies specific ultrasonic energy corresponding to at least one of an increase in fat, a decrease in fat, and an increase in elastic fibers in the skin layer or the fat layer.

[0041] When ultrasonic energy is applied, such an ultrasonic generator can selectively provide an effect of increasing or decreasing subcutaneous fat layer or improving the elasticity of the skin layer by the applied specific ultrasonic energy.

[0042] Hereinafter, the ultrasonic generator will be described in detail.

[0043] FIG. 1 is a diagram showing the configuration of the ultrasonic generator according to the present disclosure. FIG. 2 is a diagram showing, as an example, the process in which the ultrasonic generating unit irradiates ultrasonic waves.

[0044] Referring to FIGS. 1 and 2, the ultrasonic generator 100 can include an ultrasonic generation unit 110 and a control unit 120.

[0045] The ultrasonic generation unit 110 having the transducer 11 can irradiate the skin S with ultrasonic waves while maintaining the ultrasonic focusing depth.

[0046] The control unit 120 can be implemented by a memory 122 that stores data for an algorithm or a program that reproduces the algorithm for controlling the operation of components within the apparatus, and at least one processor 121 that performs the above-described operation using the data stored in the memory 122. Here, the memory 122 and the processor 121 can be implemented on separate chips. Also, the memory 122 and the processor 121 can be implemented on a single chip.

[0047] The memory 122 can store data for supporting various functions of the apparatus, a program for the operation of the control unit, can store input / output data, and can store a number of application programs (application program or application) driven by the apparatus, data for the operation of the apparatus, and instruction words. At least a part of such application programs can be downloaded from an external server via wireless communication.

[0048] Such a memory 122 can include a storage medium of at least one type among flash memory type, hard disk type, SSD type (Solid State Disk type), SDD type (Silicon Disk Drive type), multimedia card micro type, card type memory (such as SD or XD memory, etc.), random access memory (RAM), SRAM (static random access memory), read-only memory (ROM), EEPROM (electrically erasable programmable read-only memory), PROM (programmable read-only memory), magnetic memory, magnetic disk, and optical disk. Also, the memory 122 can be a database separated from this device but connected by wire or wirelessly.

[0049] The processor 121 can control the ultrasonic generator 110 so that the ultrasonic generator 110 applies specific ultrasonic energy corresponding to at least one of an increase in fat, a decrease in fat, and an increase in elastic fibers in the skin layer. At this time, the processor 121 can control the ultrasonic generator 110 so that the ultrasonic generator 110 applies specific ultrasonic energy corresponding to at least one of improving the elasticity of the skin layer or an increase in fat or a decrease in fat in the subcutaneous fat layer.

[0050] The ultrasonic generator 110 can generate a focusing point at 0.1 mm to 13 mm in the vertical direction from the skin surface for at least one of an increase in fat, a decrease in fat, and an increase in elastic fibers (Collagen, Elastin fiber). At this time, the ultrasonic generator 110 can include a dot type in which the focusing point is generated at a certain interval between the focusing points while the focusing point moves in the horizontal direction, and a linear type in which there is no distance between the focusing points.

[0051] The processor 121 can control the ultrasonic generator 110 such that the ultrasonic generator 110 applies specific ultrasonic energy in the frequency range of 2Mhz to 20Mhz at 0.1J to 3J. For example, the ultrasonic generator 110 can irradiate ultrasonic waves to the skin layer and the fat layer up to 0.1mm to 13mm in the frequency bands of 2Mhz, 4Mhz, 5.5Mhz, 7Mhz, 10Mhz, and 20Mhz.

[0052] For the increase of fat, the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.1J to 0.3J to the fat layer in the dot type of the ultrasonic generator 110. For example, the doctor checks the depth so as to focus on the fat layer of the irradiation site of the subject up to a depth of 0.1mm to 13mm of the skin, and the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.2J to the fat layer in the dot type of 2Mhz to 7Mhz of the ultrasonic generator 110.

[0053] For the reduction of fat, the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.2J to 0.6J to the fat layer or from the subcutaneous layer to the fat layer in the dot type of the ultrasonic generator 110, or to apply ultrasonic energy of 0.2J to 0.6J to the fat layer or from the subcutaneous layer to the fat layer in the linear type. For example, the doctor checks the depth so as to focus on the fat layer or from the subcutaneous layer to the fat layer of the irradiation site of the subject up to a depth of 0.1mm to 13mm of the skin, and the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.2J to 0.6J to the fat layer in the dot type of 2Mhz to 7Mhz of the ultrasonic generator 110, or in the linear type, or from the subcutaneous layer to the fat layer.

[0054] For increasing elastic fibers, the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.2 J to 0.6 J to the dermal layer in a linear type of the ultrasonic generator 110. For example, the doctor checks the depth so as to focus on the dermal layer of the irradiation site of the subject up to a depth of 0.1 mm to 13 mm of the skin, and the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.2 J to 0.6 J to the dermal layer in a linear type of 2Mhz to 20Mhz of the ultrasonic generator 110.

[0055] For increasing fat and elastic fibers, the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.1 J to 0.3 J to the fat layer in a dot type of the ultrasonic generator 110 and apply ultrasonic energy of 0.2 J to 0.6 J to the dermal layer in a linear type of the ultrasonic generator 110. For example, the doctor checks the depth so as to focus on the fat layer of the irradiation site of the subject up to a depth of 0.1 mm to 13 mm of the skin, and the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.1 J to 0.3 J to the fat layer in a dot type of 2Mhz to 20Mhz of the ultrasonic generator 110. Also, the doctor checks the depth so as to focus on the dermal layer of the irradiation site of the subject up to a depth of 0.1 mm to 13 mm of the skin, and the processor 121 can control the ultrasonic generator 110 to apply ultrasonic energy of 0.2 J to 0.6 J to the dermal layer in a linear type of 2Mhz to 20Mhz of the ultrasonic generator 110.

[0056] For fat reduction and increased elastic fibers, when the ultrasonic generator 110 moves to a specific point, the processor 121 controls the ultrasonic generator 110 to apply ultrasonic energy of 0.1 J to 0.6 J from the fat layer or the subcutaneous layer to the fat layer in the linear type of the ultrasonic generator 110, and when the ultrasonic generator 110 moves back to the origin, to apply ultrasonic energy of 0.2 J to 0.6 J to the dermis layer in the dot type of the ultrasonic generator 110. For example, the doctor checks the depth so that it is focused from the fat layer or the subcutaneous layer of the irradiation site of the subject to the fat layer up to a depth of 0.1 mm to 13 mm of the skin, and the processor 121 controls the ultrasonic generator 110 to apply ultrasonic energy of 0.1 J to 0.6 J from the fat layer or the subcutaneous layer to the fat layer in the linear type of 2 MHz to 20 MHz of the ultrasonic generator 110 when the ultrasonic generator 110 moves to a specific point, and to apply ultrasonic energy of 0.2 J to 0.6 J to the dermis layer in the dot type of 2 MHz to 20 MHz of the ultrasonic generator 110 when the ultrasonic generator 110 moves back to the origin.

[0057] On the contrary, for fat reduction and increased elastic fibers, when the ultrasonic generator 110 moves to a specific point, the processor 121 controls the ultrasonic generator 110 to apply ultrasonic energy of 0.1 J to 0.6 J from the fat layer or the subcutaneous layer to the fat layer in the dot type of the ultrasonic generator 110, and when the ultrasonic generator 110 moves back to the origin, to apply ultrasonic energy of 0.2 J to 0.6 J to the dermis layer in the linear type of the ultrasonic generator 110. For example, the doctor checks the depth so that it is focused from the fat layer or the subcutaneous layer of the irradiation site of the subject to the fat layer up to a depth of 0.1 mm to 13 mm of the skin, and the processor 121 controls the ultrasonic generator 110 to apply ultrasonic energy of 0.1 J to 0.6 J from the fat layer or the subcutaneous layer to the fat layer in the dot type of 2 MHz to 20 MHz of the ultrasonic generator 110 when the ultrasonic generator 110 moves to a specific point, and to apply ultrasonic energy of 0.2 J to 0.6 J to the dermis layer in the linear type of 2 MHz to 20 MHz of the ultrasonic generator 110 when the ultrasonic generator 110 moves back to the origin.

[0058] Figure 3 is a photograph of tissue showing fat loss results and fat gain results in an obese mouse model using the ultrasonic generator of Figure 1. Figure 4 is a graph showing the results of experiments performed at Depth1 in the upper dermis at a depth of 1 mm, Depth2 in the dermis at a depth of 2 mm, and Depth3 in the fat layer at a depth of 3 mm in an obese mouse model using the ultrasonic generator of Figure 1.

[0059] Figure 5 is a diagram showing the results of improved elasticity, fat loss, and fat gain in an obese mouse model using the ultrasonic generator of Figure 1.

[0060] When the dot type and linear type of the ultrasonic generating part of Figure 3 were applied with the same depth and the same ultrasonic energy, a photograph of the tissue observing the change of adipose tissue and Figure 4 quantitatively showed the tissue results of Figure 3 in a graph. As a result of tissue experiments in an obese mouse model, when comparing the application of 0.2 J of ultrasonic energy of the dot type to the fat layer with other conditions of Figure 3, it was confirmed that it was effective in increasing fat. And in both the dot type and linear type of the ultrasonic generating part of Figure 3 where 0.2 J to 1.0 J of ultrasonic energy was applied from the lower dermis or fat layer to the fat layer, fat decreased, but inflammatory substances were expressed from 0.7 J, and excluding this, it was confirmed that it was most effective from 0.2 J to 0.6 J.

[0061] As shown in Figure 5, it was confirmed that the fat layer grew or decreased when applying ultrasonic energy with the dot type of the ultrasonic generating part of Figure 3 and the linear type of the ultrasonic generating part of Figure 4 even in the tissue photograph.

[0062] Figure 6 is a graph showing the expression results of inflammatory substances in an obese mouse model using the ultrasonic generator of Figure 1.

[0063] Figure 6 is a numerical graph of inflammation (Macrophage 1, Inflammaroty cytokine). It was confirmed that the inflammation numerical value decreased from 0.2 J to 0.6 J in both the dot type of the ultrasonic generating part of Figure 6 and the linear type of the ultrasonic generating part of Figure 7, and the inflammation numerical value increased from 0.7 J or more.

[0064] Figure 7 is a diagram showing the results of elasticity improvement in an obese mouse model using the ultrasonic generator of FIG. 1.

[0065] Figure 7 is a Herovici stain, and it was confirmed that the increase in newly formed collagen and elastic fibers could be confirmed, and the most significant increase was observed at linear types of 0.2 J to 0.6 J.

[0066] Therefore, when ultrasonic energy is applied, the ultrasonic generator according to the present disclosure can selectively provide an increase or decrease in the subcutaneous fat layer or an effect of improving the elasticity of the skin layer depending on the applied specific ultrasonic energy and the skin layer to which the energy is applied.

[0067] On the other hand, the depths of the dermis layer and the fat layer vary depending on the person or the site, and the structure of the skin can be grasped by measuring the corresponding site with a skin measuring device, and a cartridge with a depth suitable therefor (one selected from 0.1 mm to 13 mm) can be selected.

[0068] At least one component can be added or deleted according to the performance of the components shown in FIG. 1. Also, it can be easily understood by those having ordinary knowledge in the art that the mutual positions of the components can be changed corresponding to the performance or structure of the system.

[0069] As described above, the embodiments disclosed with reference to the accompanying drawings have been described. It can be understood by those having ordinary knowledge in the technical field to which the present disclosure pertains that the present disclosure can be implemented in forms different from the disclosed embodiments without changing the technical idea and essential features of the present disclosure. The disclosed embodiments are exemplary and should not be construed in a limiting sense.
