Description

High-intensity focused ultrasound and bipolar high-frequency combined output device with suction function

[0001] The present invention relates to a device capable of sucking a skin contact area through suction and then simultaneously providing high-intensity focused ultrasound and bipolar high-frequency output.

[0002] High Intensity Focused Ultrasound (HIFU) devices are devices that utilize technology to non-invasively focus ultrasound energy on specific depths of tissue. They are widely used primarily for therapeutic and cosmetic purposes. They work by focusing ultrasound on a specific area and generating heat to treat that area.

[0003] These high-intensity focused ultrasound devices can be used on tissues of various depths, such as the skin, fat layer, and muscle layer, with the depth and intensity of the ultrasound focused being adjusted to suit the treatment purpose.

[0004] For example, high-intensity focused ultrasound (HIFU) is used to improve wrinkles and increase skin elasticity by stimulating collagen production by applying heat to the dermis or SMAS layer, or to focus on the subcutaneous fat layer to destroy fat cells as they are heated, so that the destroyed fat cells are naturally excreted from the body, thereby improving body shape.

[0005] In this regard, a prior art document for providing a high-intensity focused ultrasound generating device capable of controlling the focal length at which a thermal lesion is formed by high-intensity focused ultrasound is “High-intensity focused ultrasound generating device” (hereinafter referred to as “prior art 1”) of Korean Patent Publication No. 10-2016-0053552.

[0006] Bipolar RF devices work by using electrical energy to generate high-frequency currents between two electrodes, which in turn transfer heat energy to tissues. They are primarily used to regenerate collagen, lift, and improve elasticity in the skin.

[0007] Specifically, as high-frequency current passes through the tissue, the heat generated by resistance acts on the dermis layer of the skin, regenerating collagen and contracting the skin to provide a lifting effect.

[0008] In this regard, a prior art document for providing a high-frequency current output device capable of high-frequency continuous output of monopolar type and bipolar type or high-frequency continuous output of bipolar type and monopolar type with a single device operation includes "High-frequency current output device capable of sequential output and continuous output of monopolar type current and bipolar type current" (hereinafter referred to as "prior art 2") of Korean Patent Publication No. 10-2022-0155220.

[0009] However, in the case of existing high-intensity focused ultrasound output devices including prior art 1 or existing bipolar high-frequency output devices including prior art 2, the treatment effects are simply provided in each method and the two devices are used separately, so it is difficult to provide integrated and balanced treatment due to the limitations of each device, and the inefficiency of the treatment work continues to be highlighted, and there was a problem that the simultaneous linkage between functions was complex and did not provide a synergy effect.

[0010] The present invention was created to solve the above problems, and the purpose of the present invention is to provide a technology that simultaneously and comprehensively links the function through high-intensity focused ultrasound output and the function through bipolar high-frequency output, while also including a suction function that pulls the skin, and also expects synergy between the functions in performing this linked action.

[0011] In order to achieve the above object, the present invention provides a high-intensity focused ultrasound and bipolar radio frequency composite output device with a suction function, comprising: a housing having a cylindrical shape with a predetermined installation space inside, and including an installation body part coupled to a front end; a high-intensity focused ultrasound output module installed in the housing to generate high-intensity focused ultrasound (HIFU) in the front of the housing through a piezoelectric ceramic based on an applied electric signal; and a bipolar radio frequency output module installed in the housing to generate bipolar radio frequency (RF) in the front of the housing using a plurality of at least one pair of electrodes to which an electric signal is applied; wherein the installation body part comprises: a first body part recessed toward the rear and having a suction groove in a cup shape, and installed so that the front of the high-intensity focused ultrasound output module protrudes in the center of the front surface; And a second body part formed to extend from the outside of the first body part so as to have a ring-shaped installation surface, so that a plurality of electrodes of the bipolar high-frequency output module are exposed forward and installed to be radially evenly spread out with the front end of the high-intensity focused ultrasound output module at the center.

[0012] Here, the installation body part further includes a suction hole providing section having a tubular structure that protrudes rearward from at least one position of the first body part and has a suction hole that is opened to communicate the suction groove and the inside of the housing; and the high-intensity focused ultrasound and bipolar high-frequency composite output device further includes a suction module that is connected to the suction hole providing section and allows a ring-shaped area between an area where the front end of the high-intensity focused ultrasound output module contacts the front end of the skin in contact with the front end of the housing and an area where a plurality of electrodes of the bipolar high-frequency output module contacts the front end of the skin to be sucked rearward and sucked into the suction groove through suction when driven.

[0013] In addition, the front-to-back reference height of the front end of the high-intensity focused ultrasound output module is installed so that it protrudes further forward than the front-to-back reference height of the front end of the electrode of the bipolar high-frequency output module.

[0014] And the high-intensity focused ultrasound and bipolar high-frequency composite output device further includes a control module installed on one side of the housing and controlling the operating states of the high-intensity focused ultrasound output module, bipolar high-frequency output module, and suction module that are electrically connected.

[0015] Here, the suction module is operated through the control module, and a ring-shaped area between the area where the front end of the high-intensity focused ultrasound output module contacts the front end of the housing through suction and the area where multiple electrodes of the bipolar high-frequency output module contact the front end of the skin is sucked toward the rear and sucked into the suction groove, and at the same time, high-intensity focused ultrasound can be output to the front center through operation of the high-intensity focused ultrasound output module on the contacting skin, and bipolar high-frequency can be output around the front center through operation of the bipolar high-frequency output module.

[0016] In addition, the control module controls the operation of the high-intensity focused ultrasound output module to continuously maintain the operation of the high-intensity focused ultrasound output module when outputting high-intensity focused ultrasound to the front center, thereby allowing continuous line-shaped output to continue in conjunction with the movement through manipulation of the housing.

[0017] According to the present invention, the following effects are achieved.

[0018] First, through the combined output of high-intensity focused ultrasound (HIFU) and bipolar radiofrequency (RF), fat reduction and skin lifting can be performed simultaneously, preventing sagging skin and improving elasticity after destroying the fat layer in a single treatment.

[0019] Second, by adding a suction function, the skin and subcutaneous tissue are pulled in, allowing ultrasound and high-frequency energy to be delivered more intensively, thereby delivering energy to the tissue more efficiently, maximizing the therapeutic effect while reducing side effects.

[0020] Third, high-intensity focused ultrasound (HIFU), bipolar radiofrequency (RF), and suction function work simultaneously to complement each other and create synergy, maximizing fat reduction.

[0021] Fourth, unlike existing methods that use each device separately, the present invention enables an integrated treatment for fat reduction and skin lifting, shortening the treatment time and providing more consistent results through a synergistic effect.

[0022] Fifth, in the case of high-intensity focused ultrasound output, the output can be switched according to the existing frequency, and a point-shaped stimulation area can be formed quickly and close to a line, but rather than the form in which the actual output is continuously connected, a line-shaped stimulation area can be formed.

[0029] 1. Description of the high-intensity focused ultrasound and bipolar high-frequency combined output device

[0030] Referring to FIGS. 1 to 3, the high-intensity focused ultrasound and bipolar radio frequency composite output device (100) having a suction function of the present invention relates to a device that can selectively or compositely utilize a suction function, a function based on high-intensity focused ultrasound (HIFU) output, and a function based on bipolar radio frequency (Bipolar RF) output, and for this purpose, includes a housing (110), a high-intensity focused ultrasound output module (120), a bipolar radio frequency output module (130), a suction module (140), and a control module (150).

[0031] The housing (110) corresponds to the entire outer body corresponding to the part that the worker directly holds in his hand and performs treatment on the device, which is provided in a cylindrical shape with a predetermined installation space inside.

[0032] Here, an installation body part (115) is provided at the front end of the housing (110) to specifically limit the installation form of the extracorporeal shock wave high-intensity focused ultrasound output module (120), bipolar high-frequency output module (130), and suction module (140) to be described later.

[0033] Specifically, the installation body part (115) includes a first body part (115a) that determines the front-end installation form of the high-intensity focused ultrasound output module (120) and the suction module (140), a second body part (115b) that determines the front-end installation form of the bipolar high-frequency output module (130), and a suction hole providing part (115c) formed for connection with the suction module (150).

[0034] First, the first body part (115a) is recessed toward the rear side as shown in FIGS. 1 and 4 and has a suction groove (115T) in the shape of a cup, and the front of the high-intensity focused ultrasonic output module (120) is installed so that it protrudes at the center of the front surface.

[0035] In addition, the second body part (115b) is formed to extend from the outside of the first body part (115a) to have a ring-shaped installation surface, so that a plurality of electrodes (131) of the bipolar high-frequency output module (130) are exposed to the front side and are installed to be evenly spread radially with the front end of the high-intensity focused ultrasound output module (120) placed at the center, as shown in FIG. 2.

[0036] Most preferably, a plurality of electrodes (131) of a bipolar high-frequency output module (130) are arranged in a radially spread arrangement structure with equal spacing from each other in a circle along the installation surface of the ring-shaped second body part (115b), and it is preferable to provide at least one pair, or six or eight, as shown in FIG. 2.

[0037] Lastly, the suction hole providing portion (115c) has a tubular structure that protrudes rearward from at least one position of the first body portion (115a), and is provided with a suction hole (115H) that is open to communicate the inside of the suction groove (115T) and the inside of the housing (110).

[0038] Here, the rear end of the suction hole providing portion (115c) is connected to the front end of the suction hose, and the rear end of the suction hose is connected to the suction module (140) to be described later.

[0039] The high intensity focused ultrasound output module (120) is a device that generates high intensity focused ultrasound (HIFU) in front of the housing (110) through piezoelectric ceramics based on an applied electric signal, as illustrated in FIG. 4.

[0040] Specifically, a hemispherical or spherical piezoelectric ceramic member may be installed on the inner front side of the high intensity focused ultrasound output module (120) to generate high intensity focused ultrasound (HIFU) and provide an ultrasound stimulation area (T1) formed within a predetermined range based on a single focus on the front side.

[0041] First, the high-intensity focused ultrasonic output unit (125) installed in the high-intensity focused ultrasonic output module (120) generates a high-frequency AC electric signal as an electric signal, which is applied to a piezoelectric ceramic member, and through this, the energy of the electric signal is converted into mechanical energy in the form of vibration, thereby generating ultrasonic energy in the form of waves operating in a high frequency band (mainly 1 to 7 MHz).

[0042] Accordingly, the ultrasonic waves generated from the piezoelectric ceramic member are transmitted to a lens or a curved transducer so that the generated ultrasonic waves can be focused within a certain area (T1), thereby causing a thermal lesion due to heat generation at that point (T1).

[0043] As a result, in the area where the ultrasound is focused, the mechanical energy of the ultrasound is absorbed by the tissue, generating frictional heat. This heat does not affect the surrounding tissue, but generates high temperatures only at the specific depth where the ultrasound is focused, destroying fat cells or connective tissue in that area.

[0044] In connection with this, the control module (150) to be described later controls the operating state of the high-intensity focused ultrasonic output unit (125) to adjust the size and frequency of the high-frequency AC electric signal applied to the piezoelectric ceramic, thereby changing the intensity and focused location of the ultrasonic energy.

[0045] Most importantly, the control module (150) controls the operation of the high-intensity focused ultrasound output module (120) to continuously maintain the operation of the high-intensity focused ultrasound output module (120) when outputting high-intensity focused ultrasound to the front center, thereby allowing continuous line-shaped output to be connected to the movement through the manipulation of the housing (110).

[0046] Conventional high-intensity focused ultrasound (HIFU) devices operate by switching (On / Off) according to frequency as shown in Fig. 5(a) and mainly by quickly capturing ultrasound stimulation in the form of dots (Like Linear method). When the module moves, the dots are connected to form a linear stimulation area. However, this method has the problem that stimulation can be discontinuous in the process of capturing dots individually, and the consistency of energy transfer is low.

[0047] Accordingly, in the case of the high-intensity focused ultrasound output module (120) according to the present invention, as shown in FIG. 5(b), it is controlled to maintain continuous ultrasound output in conjunction with the control module (150), and operates in a manner (Real Linear method) in which ultrasound energy is continuously output without interruption while the housing (110) changes the phase and changes the output area, thereby forming a linear stimulation area, thereby shortening the treatment time and maintaining the consistency of energy transfer, and ensuring a uniform and more effective treatment effect.

[0048] Specifically, the high-intensity focused ultrasound output module (120) by the control module (150) maintains continuous ultrasound output, and the output ultrasound forms a line-shaped stimulation area in which the output ultrasound is continuously connected even when the output position changes due to a change in phase of the housing (110).

[0049] In this regard, the high-intensity focused ultrasonic output module (120) of the present invention may include an additional configuration that can circulate cooling water inside the device to efficiently manage heat, absorb the heat generated by the piezoelectric ceramic, and then discharge the cooling water to the outside to quickly release the heat, since heat may accumulate in the piezoelectric ceramic member due to continuous ultrasonic output, causing overheating to occur in the surroundings.

[0050] To this end, a water cooling unit (not shown) is installed around the piezoceramic member in front of the high-intensity focused ultrasound output module (120) to protect the area around the piezoceramic member on the front side of the high-intensity focused ultrasound output module (120) from overheating through heat management, while at the same time enabling continuous ultrasound output to ensure stable and safe treatment.

[0051] The bipolar high frequency output module (130) is a device that generates bipolar high frequency (Bipolar RF) in front of the housing (110) by using at least one pair of electrodes (131) to which an electric signal is applied.

[0052] Specifically, the bipolar high-frequency output module (130) is electrically connected to an electrode (131) that is arranged radially around the front end of the high-intensity focused ultrasound output module (120) in the second body part (115b) and a bipolar high-frequency output unit (132) that transmits an alternating current in the high-frequency range (200-1200 kHz) so that frictional energy caused by vibration of tissue ions generated in the process of the alternating current spreading around on the contact surface of the electrode (131) increases the temperature of the tissue, thereby forming a high-frequency stimulation area (T2) that induces coagulation necrosis.

[0053] For this purpose, electrodes (141) arranged in a configuration of 6 or 8 are arranged in pairs so that when high-frequency energy is applied to the skin from the plus electrode, it can be refluxed to the adjacent ground electrode.

[0054] As a result, the front end of the high-intensity focused ultrasound output module (120) is formed to protrude at the center based on the front of the installation body part (115) of the housing (110), and a suction groove (115T) recessed in the shape of a cup of the first body part (115a) is provided to surround it, and a structure is provided in which a plurality of electrodes (131) of a bipolar high-frequency output module (130) are radially arranged on the installation surface of the second body part (115b) surrounding the outer side of the groove structure.

[0055] In addition, the front end of the high-intensity focused ultrasound output module (120) is installed so that the front-back reference height of the front end protrudes (H) further forward than the front-back reference height of the front end of the electrode (131) of the bipolar high-frequency treatment module (130), as shown in FIG. 3.

[0056] Through this, the accuracy of the area where the ultrasound stimulation area (T1) based on high intensity focused ultrasound (HIFU) is formed through the high intensity focused ultrasound output module (120) is increased, so that the ultrasound energy is more efficiently delivered to the target tissue, and is not lost to the epidermis or other surrounding tissues, and can be focused on the target fat layer or dermis layer, and the suction area (T3) is formed more actively and deeply.

[0057] Furthermore, the relative protrusion of the front end of the high-intensity focused ultrasound output module (120) allows the ultrasound to safely reach deeper layers without interfering with the skin surface where the high-frequency stimulation area (T2) is formed through the bipolar high-frequency treatment module (130).

[0058] The suction module (140) is connected to the suction hole providing section (115c) as shown in FIG. 4, so that when driven, the high-intensity focused ultrasound output module (120) on the skin (T) that comes into contact with the front end of the housing (110) is sucked in through suction, and the ring-shaped area (T3) between the area (T1) where the high-intensity focused ultrasound output module (120) comes into contact with the skin (T) and the area (T2) where multiple electrodes (131) of the bipolar high-frequency output module (130) come into contact is sucked in toward the rear and sucked into the suction groove (115T).

[0059] Specifically, the suction module (140) allows the skin to be sucked into the suction groove (115T) through suction, thereby lifting the area from the epidermis layer - dermis layer - fascia layer - fat layer - muscle layer, so that movement can also be imparted to the muscle layer.

[0060] The control module (150) is installed on one side of the housing (110) so as to be electrically connected to the high-intensity focused ultrasound output unit (125) of the high-intensity focused ultrasound output module (120), the bipolar high-frequency output unit (135) of the bipolar high-frequency output module (130), and the suction module (140) to control the operating status of each component.

[0061] That is, the operating states of the high-intensity focused ultrasound output unit (125) of the high-intensity focused ultrasound output module (120), the bipolar high-frequency output unit (135) of the bipolar high-frequency output module (130), and the suction module (140) are controlled through a control command generated based on a signal input to the control module (150), so that the functions of high-intensity focused ultrasound output, bipolar high-frequency output, and suction can all be performed simultaneously or selectively.

[0062] Most preferably, in order to maximize the effect, the control module (150) operates the suction module (140) so that the ring-shaped area (T3) between the area (T1) where the front end of the high-intensity focused ultrasound output module (120) contacts the front end of the housing (110) through suction and the area (T2) where multiple electrodes (131) of the bipolar high-frequency output module (130) contact the skin is sucked toward the rear and sucked into the suction groove (115T), and at the same time, the high-intensity focused ultrasound is output to the front center through the operation of the high-intensity focused ultrasound output module (120) and the bipolar high-frequency output module (130) is output to the periphery of the front center.

[0063] 2. Description of fat reduction effect test using high-intensity focused ultrasound and bipolar high-frequency combined output device

[0064] A test was conducted to verify the actual clinical effect using a high-intensity focused ultrasound and bipolar high-frequency composite output device (100) equipped with a suction function according to the present invention described as described above, and a test was conducted to observe changes in the level of fat reduction and skin elasticity before and after use for each embodiment by setting differences in the control form between the configurations through the control module (150).

[0065] (1) Classification of operating embodiments

[0066] -First embodiment: Simultaneously activating the high-intensity focused ultrasound output module (120), the bipolar high-frequency output module (130), and the suction module (140) through the control module (150).

[0069] -Fourth embodiment: Simultaneously activating the bipolar high-frequency output module (130) and the suction module (140) through the control module (150).

[0070] (2) Fat reduction and elasticity test

[0071] For each example, five test subjects were selected, and an area measuring 10 cm wide x 10 cm long on the front of the thigh was set as the output area, and the thigh thickness and elasticity level were measured before using the device.

[0072] After that, for the high-intensity focused ultrasound output module (120), the output intensity was set to the same frequency of 3 MHz and energy intensity of 2.0 J / cm² and then maintained, and for the bipolar high-frequency output module (130), the output intensity was set to the same temperature of 40°C and then maintained, and the output was applied for 30 minutes a day for 7 days, after which changes in the thickness and elasticity of the thighs were measured.

[0073] Changes in skin elasticity were measured by applying vibration stimulation to the skin surface using the 'DermaLab Elasticity Module (Cortex Technology)' equipment based on the test method of 'ISO 19399:2016', and analyzing the skin's ability to deform and restore in response to the stimulation. The skin's response to the applied pressure was calculated in Pascal (Pa).

[0074] The changes in thigh thickness and elasticity that occurred in this way were calculated by averaging the results of 10 people for each example, and the results are shown in Tables 1 and 2 below.

[0077] As shown in Table 1, when the high-intensity focused ultrasound output module (120), the bipolar high-frequency output module (130), and the suction module (140) are simultaneously activated through the control module (150) according to Example 1 so that the suction area (T3) is sucked toward the rear side and sucked into the suction groove (115T), and the high-intensity focused ultrasound is output to the front center through the operation of the high-intensity focused ultrasound output module (120) and the bipolar high-frequency output module (130) is simultaneously output to the periphery of the front center, it can be seen that the average value of the change in thigh thickness through fat reduction reaches '-1.98 cm' and the reduction rate is about 3% to 4%, showing a great effect compared to other examples. In addition, as shown in Table 2, when the high-intensity focused ultrasound output module (120), the bipolar high-frequency output module (130), and the suction module (140) are activated through the control module (150) according to Example 1, When the high-intensity focused ultrasound output module (120) is activated at the same time so that the suction area (T3) is sucked toward the rear side and sucked into the suction groove (115T), and high-intensity focused ultrasound is output to the front center, and at the same time, bipolar high-frequency is output to the periphery of the front center through the operation of the bipolar high-frequency output module (130), it can be seen that the average change value with respect to improvement in skin elasticity reaches '58.2 Pa' and the improvement rate is about 22% to 23%, showing a great effect compared to other examples.

[0078] Therefore, in terms of the configuration of the high-intensity focused ultrasound and bipolar high-frequency composite output device (100) equipped with a suction function according to the present invention, the installation form and driving form of the high-intensity focused ultrasound output module (120), the bipolar high-frequency output module (130), and the suction module (140) simultaneously and comprehensively provide the high-intensity focused ultrasound output function and the bipolar high-frequency output function while maintaining the suction function, thereby enhancing the functional level and also greatly improving the synergy between the functions in performing this linked operation.
