Description

Dual ultrasonic handpiece with HIFU function}

The present invention relates to a dual ultrasound handpiece having a high-density focused ultrasound function, and more particularly, it is possible to irradiate dual ultrasound waves of different frequencies at once, and a high-density focused ultrasound handpiece that can make users feel convenient and contribute to sales increase due to a shortened irradiation time. It relates to a dual ultrasonic handpiece having an ultrasonic function.

In the case of the skin, it is divided into three layers, such as the epidermis layer, the dermis layer, and the subcutaneous fat layer, sequentially from the surface. To explain this in detail, the epidermal layer is the most superficial layer of the skin. Depending on its location and function, it consists of several layers such as the stratum corneum, transparent layer, granular layer, prickle layer, and basal layer, and is responsible for functions such as protection, defense, and secretion. .

In the case of the dermal layer, it is located below the epidermal layer and is located adjacent to the basal layer and constitutes most of the skin. The papillary layer is where capillaries and lymphatic vessels are located because moisture, proteins, carbohydrates, mucopolysaccharides, minerals, and mineral salts are in a jelly state. , It is composed of collagen, a collagen fiber related to skin wrinkles, and elastin, an elastic fiber that gives skin elasticity, and a reticular layer containing a matrix.

In addition, the subcutaneous fat layer is located between the dermis, muscles and bones and contains a large amount of fat. It constitutes the lowest layer of the skin. It not only prevents internal damage, but also prevents loss of body heat and maintains body temperature.

Recently, in relation to the skin, many skin care devices using ultrasonic waves have been developed for beauty of the skin. In the case of a skin beauty device using ultrasonic waves, some of the ultrasonic waves are absorbed into the skin and converted into heat to generate heat within the skin to help tissue activation and to prevent the absorption of drugs or cosmetics of micromolecule active ingredients into the skin due to ultrasonic waves. help

The prior art related to such a skin care device is a handpiece provided as a handle to the user, such as 'Korean Intellectual Property Office Publication Patent No. 10-2021-0097573 skin treatment device'; a high-frequency electrode disposed at an end of the handpiece and contacting the skin to transmit high-frequency energy; and a sleeve that surrounds an edge of the high frequency electrode to entirely expose the surface of the high frequency electrode and protrudes beyond the surface of the high frequency electrode to prevent the skin from contacting the edge area of the surface of the high frequency electrode.

However, in the case of most ultrasonic skin care devices including these conventional technologies, the device is used in such a way that after skin care is performed with ultrasonic waves of a specific frequency, the frequency is changed to repeatedly perform skin care with ultrasonic waves of different frequencies. In this way, when skin care is performed by changing the necessary frequency, there is a problem in that the management time increases and the user receiving the care may become bored, and many users find it difficult to increase sales due to time constraints for use.

1 is a front view of a dual ultrasound handpiece according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the dual ultrasound handpiece.

The dual ultrasound handpiece 10 having a high-density focused ultrasound function according to the present invention includes a handpiece unit 100, an ultrasound irradiation unit 200, and a focusing lens 300, as shown in FIG.

First, the hand piece unit 100 corresponds to the exterior of the double ultrasonic hand piece 10, and includes a hand piece body 110, a handle portion 120, a contact portion 130, and an irradiation button 140.

The handpiece body 110 has a cylindrical shape and constitutes the exterior of the double ultrasonic handpiece 10, and within the handpiece body 110, electrical energy is output so that ultrasonic waves are output through an ultrasonic irradiation unit 200 to be described later. A charging terminal (not shown) is provided to provide a wired/wireless charging through the charging terminal. In addition, a PCB board (not shown) is provided in the handpiece body 110 so that ultrasonic waves can be output, and this PCB board is connected to the ultrasonic irradiation unit 200.

The handle part 120 is formed at one end of the handpiece body 110, and has a curved shape so that the user using the double ultrasonic handpiece 10 can stably grip the handpiece body 110. It is desirable that If the handle part 120 is formed in a general cylindrical shape, a user may slip out of the hand while using the double ultrasonic handpiece 10 and miss it. Therefore, it is preferable that the handle part 120 is made of a curved shape so that the user can stably feel the grip.

The contact part 130 is formed at the other end of the handpiece body 110 and has a through hole 131 formed in the central area, and irradiates the first ultrasound wave and the second ultrasound wave to the skin using the ultrasonic irradiation unit 200. It corresponds to a configuration that is used in direct contact with the skin or placed in close proximity to the skin. The contact part 130 is preferably made of a material that does not cause hygiene problems so as not to cause inflammation on the contacting skin, and is most preferably made of a metal material that minimizes the proliferation of bacteria or viruses.

The through hole 131 is connected to the inside of the handpiece body 110 and serves as a passage so that the first and second ultrasonic waves of the ultrasonic irradiation unit 200 installed in the handpiece body 110 are irradiated to the outside. do A condensing lens 300 to be described later is installed in the through hole 131 .

The irradiation button 140 is formed on the handpiece body 110 and serves to control irradiation of the first ultrasound and the second ultrasound, which will be described later. That is, when the user presses the irradiation button after positioning the dual ultrasonic handpiece 10 so as to be close to the skin requiring irradiation of the first and second ultrasonic waves, the first and second ultrasonic waves are irradiated to enable skin care. .

The ultrasonic irradiation unit 200 is installed in the handpiece body 110 to irradiate the skin with first and second ultrasound waves, and includes a first irradiation unit 210 and a second irradiation unit 220.

The first irradiator 210 is installed in the handpiece body 110 and has a configuration for irradiating a first ultrasonic wave toward the through hole 131, and corresponds to an ultrasonic wave of 3 to 10Mhz in the case of the first ultrasonic wave. The first ultrasonic wave irradiated in this range corresponds to a frequency with an amplitude smaller than the thickness of the cell wall, and can give an ultrasonic massage effect to the smallest particles in the cell, creating effective and safe heat in the epidermal layer that causes skin diseases. do. In detail, the first ultrasonic wave of 3 to 10 Mhz can penetrate the epidermal layer and the dermal layer to stimulate collagen, elastin, and hyaluronic acid to manage the skin glossyly.

The second irradiator 220 is configured to irradiate a second ultrasonic wave of a different frequency from the first irradiator 210, and in the case of the second ultrasonic wave, it means an ultrasonic wave of 1 to 3 MHz corresponding to a lower frequency than the first ultrasonic wave. The second ultrasound passes through the epidermis and dermis to reach the subcutaneous fat layer, and the second ultrasound that reaches the subcutaneous fat layer serves to decompose fat in the subcutaneous fat layer, unlike the first ultrasound.

In the case of a conventional skin beauty device, first ultrasound is mainly used for skin regeneration, and second ultrasound is mainly used for fat decomposition. That is, either one of the first ultrasound and the second ultrasound is selected and used according to the purpose, and if you want to use both the first ultrasound and the second ultrasound, use the first ultrasound and then the second ultrasound sequentially. You are choosing how to investigate. However, in the case of the double ultrasonic handpiece 10 according to the present invention, the first and second ultrasonic waves can be irradiated to the skin at once by driving the first irradiation unit 210 and the second irradiation unit 220 at the same time, so that the skin care time is reduced. It has the advantage of being shortened.

Each of the first irradiation unit 210 and the second irradiation unit 220 is made of a high intensity focused ultrasound (HIFU) element. In the case of the HIFU device, high-intensity ultrasonic energy is concentrated into one focus so that the ultrasonic wave acts on all of the epidermis, dermis, and subcutaneous fat layers. there is. That is, the first ultrasonic wave irradiated from the first irradiation unit 210 and the second ultrasound wave irradiated from the second irradiation unit 220 may be irradiated at a high density.

The condensing lens 300 is installed in the through hole 131 and has a configuration for concentrating the first ultrasound and the second ultrasound into one focus, the first irradiation unit 210 and the second irradiation unit 220 corresponding to the HIFU element The first ultrasound and the second ultrasound are respectively concentrated into one focus so that the first ultrasound and the second ultrasound can be irradiated together to a localized area of the skin. In this way, when the first ultrasound and the second ultrasound are irradiated together to the local area, a synergistic effect of skin beauty can be obtained by removing fat and at the same time promoting the production of collagen, elastin, and hyaluronic acid. The condensing lens 300 is preferably composed of a convex lens, but is not limited thereto.

In the case of a conventional skin care device, in order to irradiate the skin with ultrasonic waves of various frequencies, it is used by irradiating the skin with ultrasonic waves of a first frequency and then repeatedly irradiating the skin with ultrasonic waves of different frequencies. done In this case, there is a problem in that users feel bored because the use time of the skin care device is long, and many users find it difficult to increase sales because there is a time constraint for use.

On the other hand, when using the dual ultrasound handpiece 10 having a high-density focused ultrasound function according to the present invention, the first ultrasound and the second ultrasound having different frequencies can be irradiated at once, and the user feels convenience and sales due to the shortened irradiation time. There are various advantages such as being able to contribute to the rise.
