Description

[Technical Field]

[0001] The present invention relates to a lifting cosmetic device using high intensity focused ultrasound, and more particularly to a lifting cosmetic device using high intensity focused ultrasound that can selectively change the irradiation depth of high intensity focused ultrasound (HIFU) so that HIFU can selectively reach the SMAS (Superficial Musculo Aponeurotic System) layer, which is a fibrofascial layer that is a part of the muscle layer, or the dermis layer. [Background technology]

[0002] Generally, many people are beginning to take an interest in beauty, and interest in skin care is also increasing day by day.

[0003] The desire for healthy skin is not limited to the cosmetic field alone, but is also influencing the growth of the medical field, which seeks to protect healthy skin from increased ultraviolet radiation due to the destruction of the ozone layer and various types of pollution.

[0004] Face lifting is a wrinkle removal procedure that aims to improve the appearance of aging on the face by removing loose skin from the face and neck and lifting the subcutaneous tissue to remove wrinkles.

[0005] Recently, endoscopic methods have been used to minimize scars by making as few incisions as possible during facelifts.

[0006] However, since these methods are invasive surgical procedures, they pose many drawbacks to the patient, such as bleeding, secondary infection, pain, and a long recovery period.

[0007] Although advanced medical technologies such as lasers have been developed and commercialized for invasive procedures, the drawbacks inherent in invasive surgery still persist.

[0008] Therefore, there is a growing need for a technology that can beautify the skin in a non-invasive manner.

[0009] Generally, the SMAS layer, which is part of the muscle layer, is the area that is pulled during face lifting surgery. However, when high-intensity focused ultrasound is used to affect only the SMAS layer without touching the epidermis, the heat from the ultrasound is transmitted deep into the dermis, which regenerates collagen, resulting in a synergistic effect of wrinkle reduction and skin elasticity, as reported in clinical results overseas.

[0010] In line with this trend, non-invasive beauty devices that use high intensity focused ultrasound (HIFU) have recently been gaining attention.

[0011] For skin cosmetic treatments, there are ultrasound cosmetic devices that perform skin lifting or skin tightening treatments by irradiating high-intensity focused ultrasound to shallow skin tissue. The ultrasound cosmetic device irradiates high-intensity focused ultrasound (HIFU) to the subcutaneous fat layer and dermis layer, etc., to burn or melt and decompose the subcutaneous biological tissue, stimulating it and improving skin wrinkle reduction and elasticity.

[0012] As prior art, reference can be made to Korean Patent Registration No. 10-1335476 (November 26, 2013). Summary of the Invention [Problem to be solved by the invention]

[0018] In this case, the rotational force transmission means according to the present invention includes a connecting gear that meshes with the motor gear, and a first bevel gear that is connected to the connecting gear by a shaft and rotates in conjunction with the rotation of the connecting gear.

[0019] In addition, the head transport means according to the present invention includes a rotary shaft having a second bevel gear on one side that meshes with the first bevel gear at a right angle, and a first spur gear on the other opposite side, and a transport screw having a second spur gear on the other side that is parallel to the rotary shaft and has a screw thread formed along its length and meshes with the first spur gear.

[Effects of the Invention]

[0022] The effects achieved by the lifting cosmetic device using high intensity focused ultrasound according to the present invention are as follows.

[0024] In addition, the irradiation depth of the high intensity focused ultrasound (HIFU) can be selectively changed, eliminating the need to replace the ultrasound irradiation plug, shortening the treatment time and reducing the fatigue of the practitioner. [Brief explanation of the drawings]

[0027] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms and words used in the specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted as meanings and concepts that correspond to the technical ideas of the present invention, based on the principle that the inventor can appropriately define the concepts of terms in order to best describe his / her invention.

[0028] Therefore, it should be understood that the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent the technical ideas of the present invention, and that there may be equivalent modifications that can replace them at the time of this application.

[0029] The present invention relates to a lifting cosmetic device using high intensity focused ultrasound (HIFU) that can selectively change the irradiation depth of HIFU so that HIFU can selectively reach the SMAS layer, which is a fibrofascial layer that is a part of the muscle layer, or the dermis layer, and will be described below with reference to the drawings.

[0030] The lifting cosmetic device using high intensity focused ultrasound according to one embodiment of the present invention, as shown in FIGS. 1 to 7, includes a body part 100 and a cartridge part 200. The overall shape of the ultrasonic lifting cosmetic device is streamlined, with the cartridge part 200 located at the top and the body part 100 located below the cartridge part 200.

[0031] Therefore, the user holds the body part 100 in his / her hand, and then moves the lifting beauty device along the skin line with the front side of the cartridge part 200 in contact with the skin, and irradiates high intensity focused ultrasound (HIFU) to the SMAS layer, which is a fibrofascial layer that is part of the muscle layer, or the deep layer of the dermis layer to perform the lifting treatment.

[0032] Here, the body part 100 and the cartridge part 200 according to an embodiment of the present invention will be described in more detail as follows.

[0033] First, the body part 100 is held by the user's hand around its periphery, and generates power output and rotational force capable of driving the cartridge part 200 when the user operates a plurality of operation buttons 112 exposed on the surface.

[0034] In this case, the body part 100 includes a body housing 110, a battery 120, and an electric motor 130. The body housing 110 forms a space therein, and the battery 120 and the electric motor 130 are housed in the space.

[0035] Here, a coupling part 111 into which the lower part of the cartridge part 200 is inserted is formed on the upper side of the body housing 110, and a motor gear 131 is provided at the center of the interior of the coupling part 111 to provide rotational force, which is the power for moving the ultrasonic oscillation head 300 provided on the cartridge part 200, and a pair of terminals 121 for supplying power to drive the ultrasonic oscillation head 300 are provided on both the left and right sides of the motor gear 131 at the center.

[0036] In addition, support pieces 113 are formed on the upper left and right sides of the coupling part 111, extending in an arc shape toward the cartridge part 200, and the support pieces 113 support the cartridge part 200 so that it does not separate from the coupling part 111 due to physical force applied from the side of the cartridge part 200 coupled to the coupling part 111.

[0037] Preferably, the coupling part 111 further includes a locking means 114 for locking the cartridge part 200 inserted into the coupling part 111 so that the cartridge part 200 cannot be easily removed.

[0038] The locking means 114 is supported by an elastic body (not shown) and is connected to a push button formed on the surface of the body housing 110. The locking means 114 moves forward and backward by the force applied forward and backward through the push button, thereby releasing the engagement of the cartridge part 200.

[0039] The battery 120, which is housed in the lower part of the internal space of the body housing 110, selectively supplies power to the electric motor 130 and the cartridge unit 200, and is preferably a rechargeable battery that can be charged with electricity.

[0040] At this time, the battery 120 is electrically connected to a charging terminal 115 provided at the lower end of the body housing 110, and is connected to an external power source through the charging terminal 115 to be charged with electricity.

[0041] In addition, the battery 120 is electrically connected to a control board (not shown) built into the body housing 110, and the control board is electrically connected to an operation button 112 to control the power supplied to the electric motor 130 and the cartridge part 200 by turning the device on / off, selecting an operation mode, selecting the irradiation depth, etc.

[0042] The battery 120 is electrically connected to a pair of terminals 121 provided in the coupling part 111 through the control board, and supplies power to the ultrasonic oscillation head 300 provided in the cartridge part 200 .

[0043] The electric motor 130, which is installed in the upper part of the internal space of the body housing 110, is electrically connected to the battery 120 and a control board like a conventional electric motor, and generates forward or reverse rotational force using power supplied from the battery 120 under the control of the control board.

[0044] At this time, a motor gear 131 located at the center of the coupling part 111 of the body housing 110 is coupled to the rotary shaft of the electric motor 130, and the motor gear 131 is a crown gear that rotates forward or backward in conjunction with the rotation of the rotary shaft of the electric motor 130.

[0045] The cartridge part 200 is connected to the coupling part 111 of the body part 100, and irradiates high intensity focused ultrasound (HIFU) by using power generated from the body part 100, selectively changing the irradiation depth in two stages.

[0046] Here, to explain the cartridge part 200 in more detail, the cartridge part 200 according to an embodiment of the present invention includes a cartridge housing 210, a rotational force transmitting means 220, a head moving means 230, and a head module 240.

[0047] First, the cartridge housing 210 forms a space inside, and the rotational force transmission means 220, the head transfer means 230, the head module 240, and the guide member 250 are built in the internal space.

[0048] 4 and 5, the rotational force transmission means 220 transmits the rotational force generated by the electric motor 130 of the body part 100 to the head moving means 230, and includes a connecting gear 221 that meshes with the motor gear 131, and a first bevel gear 222 that is connected to the connecting gear 221 by an axis.

[0049] In this case, it is preferable that the connecting gear 221 is also formed as a crown gear so as to mesh with the motor gear 131, and the shaft connecting the connecting gear 221 and the first bevel gear 222 is fixed to the cartridge housing 210 by a bearing or the like so as to be rotatable.

[0050] Therefore, the rotational force transmission means 220 receives the rotational force generated by the electric motor 130 of the body part 100 through the connecting gear 221 and outputs it to the first bevel gear 222 connected to the connecting gear 221 by a shaft.

[0051] Here, a pair of connect pins 211 are provided at the bottom of the cartridge housing 210 at positions corresponding to a pair of terminals 121, with the connecting gear 221 of the rotational force transmission means 220 at the center. The connect pins 211 are electrically connected to the ultrasonic oscillation head 300, and when the cartridge part 200 is connected to the coupling part 111 of the body part 100, they are inserted into the terminals 121 and electrically connected.

[0052] Therefore, electricity is supplied to the ultrasonic oscillation head 300 provided in the cartridge part 200 by the connection between the terminal 121 and the connect pin 211 .

[0053] The head transfer means 230 is mechanically connected to the rotational force transmission means 220 to linearly transfer the head module 240 .

[0054] The head transfer means 230 includes a rotary shaft 231 and a transfer screw 234 whose axial directions are parallel to each other. A second bevel gear 232 is provided on one side of the rotary shaft 231, and is engaged with the first bevel gear 222 of the rotational force transmission means 220 at a right angle to change the rotation direction so that the rotation direction is perpendicular to the first bevel gear 222. A first spur gear 233 is provided on the other side of the rotary shaft 231, and the first spur gear 233 also rotates with the axial rotation of the rotary shaft 231.

[0055] A second spur gear 235 that meshes with the first spur gear 233 is provided on the other side of the transfer screw 234, which is arranged parallel to the rotation shaft 231. The rotation shaft 231 rotates due to the rotational force transmitted through the second bevel gear 232 that meshes with the first bevel gear 222 of the rotational force transmission means 220. When the first spur gear 233 rotates due to the rotation of the rotation shaft 231, the meshed second spur gear 235 rotates, causing the transfer screw 234 to rotate, and the head module 240 connected to the transfer screw 234 moves linearly.

[0056] The head module 240 includes a first head holder 241 coupled to the feeding screw 234 and moving along the axial direction of the feeding screw 234 as the feeding screw 234 rotates.

[0057] In this case, the first head holder 241 has an overall U-shape, and a cam block 242 is formed extending from the underside of the first head holder 241. The cam block 242 corresponds to a pair of position sensors 260 arranged on one end and the other end of the transfer screw 234, and can confirm the position of the ultrasonic oscillation head 300.

[0058] The second head holder 243 is connected to the upper side of the first head holder 241, and the ultrasonic oscillation head 300 is attached to the front end of the second head holder 243, which is connected between the upper parts of the first head holder 241 forming a "U" shape.

[0059] In this case, coupling protrusions are formed on both the left and right sides of the second head holder 243, and coupling holes into which the coupling protrusions are inserted are formed in the first head holder 241. The coupling holes are formed as elongated holes having lengths in the vertical direction, so that the second head holder 243 can move above the first head holder 241 by the length of the coupling holes.

[0060] 4 to 7, the second head holder 243 is provided with a guide rotation pin 244, which is rotatably provided on the second head holder 243 and has guides 245 with semicircular cross sections at both ends.

[0061] In this case, the guide 245 of the guide rotation pin 244 corresponds to a pair of guide plates 250 provided on the front and rear sides of the head module 240, and the guide plates 250 have track grooves 251 formed thereon to guide the guide 245 of the guide rotation pin 244.

[0062] The track groove 251 preferably has an elliptical shape formed by combining first and second high intensity focused ultrasound irradiation sections 251a and 251b with irradiation depth conversion sections 251c and 251d on both the left and right sides, and the inside of the track groove 251 is in close contact with the flat surface of the semicircular guide 245, and the outside of the track groove 251 is in close contact with the curved portion of the guide 245.

[0063] Here, the first high intensity focused ultrasound irradiation section 251a and the second high intensity focused ultrasound irradiation section 251b are sections in which the ultrasound oscillation head 300 connected to the second head holder 243 irradiates high intensity focused ultrasound (HIFU), and it is preferable that the first high intensity focused ultrasound irradiation section 251a and the second high intensity focused ultrasound irradiation section 251b are straight sections parallel to each other, and it is preferable that the first high intensity focused ultrasound irradiation section 251a limits the irradiation depth of the focused ultrasound to 3.0 mm, and the second high intensity focused ultrasound irradiation section limits the irradiation depth of the focused ultrasound to 4.5 mm.

[0064] Therefore, the lifting cosmetic device using high intensity focused ultrasound according to one embodiment of the present invention has two irradiation depths of focused ultrasound, 4.5 mm and 3.0 mm, and can selectively irradiate high intensity focused ultrasound to the SMAS layer, which is a fibrofascial layer, and the dermis layer, respectively, or can irradiate high intensity focused ultrasound to both the SMAS layer and the dermis layer.

[0065] The irradiation depth changing sections 251c and 251d, where the irradiation depth is changed, are formed to include a straight path and a curved path so that the guide 245 can rotate along the track groove 251.

[0066] Therefore, it is desirable that the guide 245 that moves along the track groove 251 moves along the track groove 251 in only one direction.

[0067] Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely illustrative, and those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of protection of the present invention should be determined by the technical spirit of the claims.
