Description

Technology Field

[0001] The present invention relates to a skin care device capable of controlling the penetration depth of focused ultrasound penetrating the skin. Background Technology

[0003] Generally, ultrasound is an inaudible sound wave with a vibration frequency of 17,000 to 20,000 Hz or higher that cannot be heard by the human ear, vibrating more than 20,000 times per second. Recently, the scope of use for treatment or cosmetic purposes utilizing such ultrasound is expanding.

[0004] Meanwhile, high intensity focused ultrasound (HIFU) is a procedure that burns away tissue using high heat of 65 to 100°C generated at each focal point when high-intensity ultrasound energy generated from a transducer is focused in one place.

[0005] This focused ultrasound therapy is harmless to the human body and generates heat only at the focal point where the ultrasound is focused, eliminating the need for general anesthesia or skin incision; as a result, it is currently being utilized in the treatment of various cancers such as liver cancer, breast cancer, and uterine cancer.

[0006] High intensity focused ultrasound (HIFU), which has been utilized in the medical field, is recently being used in cosmetic dermatology. Specifically, by using HIFU to strongly deliver focused ultrasound energy to the lower dermis, the boundary layer between the dermis and subcutaneous fat, the SMAS layer (fibrous tissue of the fat layer), and the fascia to provide overall skin care such as wrinkle removal, high intensity focused ultrasound is now being utilized in the field of cosmetic dermatology as well.

[0007] Meanwhile, since ultrasonic transducers are set to a single frequency and single focus, multiple devices (cartridges) with different focusing distances must be provided to vary the penetration depth of the ultrasound into the skin according to the purpose of the procedure, and these multiple devices must be switched according to the purpose of the procedure.

[0008] Therefore, there is a need for a beauty device that can set different penetration depths of ultrasound into the skin to suit various treatment purposes using a single device. Prior art literature

[0023] As illustrated in the drawings, a skin beauty device (10) according to one embodiment of the present invention is capable of adjusting the penetration depth (D) of focused ultrasound penetrating the skin, and comprises: a housing part (203) having a coupling groove (301) formed on the inside and a plurality of transmission windows (201) formed so that ultrasound is transmitted so that ultrasound is transmitted to the skin that is in close contact with the skin; a guide part (303) rotatably provided in the coupling groove (301); and an ultrasound generating part (305) provided in the guide part (303) and outputting ultrasound so that ultrasound is transmitted to one of the plurality of transmission windows (201) as the guide part (303) rotates, wherein the housing part (203) is characterized in that the plurality of transmission windows (201) are formed spaced apart at a certain interval along the rotation direction of the guide part (303).

[0024] One embodiment of the present invention relates to a skin care device (10) for controlling the penetration depth (D) of focused ultrasound penetrating the skin through a single device.

[0025] Below, each component is described in detail.

[0026] First, the housing part (203) has a coupling groove (301) formed therein, in which an ultrasonic generating part (305) is rotatably and movably provided.

[0027] Here, the coupling groove (301) can be formed by being recessed in a cylindrical shape on the side of the housing part (203).

[0028] Additionally, the housing portion (203) has a rotational coupling groove (329) formed on the inner surface facing the opening of the coupling groove (301), into which the end of the guide portion (303) is rotatably coupled.

[0029] Meanwhile, the housing part (203) has a plurality of transparent windows (201) that are in close contact with the skin.

[0030] Here, a plurality of transmission windows (201) transmit ultrasound output from the ultrasound generator (305) and perform the function of transmitting the transmitted ultrasound to the operator's skin.

[0031] At least two transparent windows (201) can be formed in this housing part (203).

[0032] Additionally, the housing part (203) has a plurality of transparent windows (201) formed at regular intervals along the rotational direction of the guide part (303).

[0033] For example, the housing part (203) may include a first transparent window (205) formed on the upper side, a second transparent window (207) spaced apart at a certain distance in the rotational direction of the first transparent window (205) and the guide part (303), and a third transparent window (209) spaced apart at a certain distance in the rotational direction of the second transparent window (207) and the guide part (303).

[0034] The first transparent window (205) may be formed on the front side of the housing part (203), the third transparent window (209) may be formed on the upper side of the housing part (203), and the second transparent window (207) may be formed between the first transparent window (205) and the third transparent window (209).

[0035] Meanwhile, the housing part (203) is characterized by the fact that the distance (S) from the ultrasonic generating part (305) to the plurality of transmission windows (201) is different from each other.

[0036] In one embodiment of the present invention, as the distance (S) from the ultrasound generating unit (305) to each transmission window (201) is different from each other, the distance from the ultrasound generating unit (305) to the skin in contact with each transmission window (201) is different from each other, and thereby the penetration depth (D) of the ultrasound penetrating into the skin in contact with each transmission window (201) can be different from each other.

[0037] For example, the distance (S2) from the ultrasonic generator (305) to the second transparent window (207) may be greater than the distance (S1) from the ultrasonic generator (305) to the first transparent window (205), and the distance (S3) from the ultrasonic generator (305) to the third transparent window (209) may be greater than the distance (S2) from the ultrasonic generator (305) to the second transparent window (207).

[0038] In addition, the housing part (203) of the present invention is characterized in that the distances from the rotation center (C) of the ultrasonic generating part (305) to the plurality of transmission windows (201) are different from each other.

[0039] That is, the distance from the center of rotation (C) to the second viewing window (207) may be greater than the distance from the center of rotation (C) to the first viewing window (205), and the distance from the center of rotation (C) to the third viewing window (209) may be greater than the distance from the center of rotation (C) to the second viewing window (207).

[0040] More specifically, the distance from the inner surface of the coupling groove (301) to the plurality of transparent windows (201) of the housing part (203) may differ from each other.

[0041] That is, the shortest distance from the inner surface of the coupling groove (301) to each transparent window (201) of the housing part (203) may be different from each other.

[0042] For example, the shortest distance (S5) from the inner surface of the coupling groove (301) to the second viewing window (207) may be greater than the shortest distance (S4) from the inner surface of the coupling groove (301) to the first viewing window (205), and the shortest distance (S6) from the inner surface of the coupling groove (301) to the third viewing window (209) may be greater than the shortest distance (S5) from the inner surface of the coupling groove (301) to the second viewing window (207).

[0043] As such, in one embodiment of the present invention, by rotating the ultrasound generating unit (305) through the guide unit (303), each transmission window (201) having a different ultrasound penetration depth (D) can be selectively used, thereby allowing various procedures to be performed according to the purpose of the procedure without replacing the skin beauty device (10).

[0044] Meanwhile, the lower part (203) according to one embodiment of the present invention may further include a beauty device coupling part (309) provided on the lower side and detachably coupled to the beauty device body (20).

[0045] The beauty device coupling part (309) has a PCB substrate (307) placed inside and coupled thereto.

[0046] That is, one embodiment of the present invention is configured to be detachably attached to a beauty device body (20) equipped with a power supply unit (not shown) for supplying power and a control unit (not shown) for controlling power and operation.

[0047] Furthermore, the guide portion (303) is rotatably provided on the inner side of the housing portion (203).

[0048] More specifically, the guide portion (303) is rotatably coupled to a coupling groove (301) formed in a cylindrical shape on the side of the housing portion (203).

[0049] To explain the structure of the guide section (303) in more detail, the guide section (303) includes: a rotation guide (311) whose outer surface is rotatably coupled to the inner surface of the coupling groove (301); and a transfer guide (315) that extends from one side of the rotation guide (311) and has a receiving groove (313) formed therein, in which an ultrasonic generating section (305) is provided.

[0050] Additionally, the guide portion (303) further includes a rotary handle (319) which is coupled to the other side of the rotary guide (311) and configured to allow the ultrasonic generating portion (305) to be rotated through the handle (317).

[0051] First, the rotation guide (311) is formed in a cylindrical shape, and its outer surface is rotatably coupled to the inner surface of the coupling groove (301).

[0052] This rotary guide (311) has a sealing member coupling groove (323) formed on its outer surface to which a sealing member (321) is coupled.

[0053] In addition, the rotary guide (311) has a motor coupling groove (327) formed on its inner side, in which a driving motor (325) to be described later is provided.

[0054] Next, the transfer guide (315) extends from one side of the rotation guide (311).

[0055] The end of this transfer guide (315) is rotatably coupled to the inner surface of the housing part (203), more specifically, a rotational projection (331) protruding from the end is rotatably coupled to the rotational coupling groove (329).

[0056] Additionally, the transfer guide (315) has an open top and a receiving groove (313) formed therein, which allows the ultrasonic generating part (305) to move.

[0057] And, the transfer guide (315) is recessed at the end of the receiving groove (313) to form a fixing groove (335) to which the end of the transfer screw (333), to be described later, is coupled.

[0058] In addition, the transfer guide (315) has a guide groove (337) formed on the inner side of the receiving groove (313) to which the ultrasonic generating part (305) is movably coupled.

[0059] The guide groove (337) is formed along the receiving groove (313) and guides the ultrasonic generating part (305) to move along the longitudinal direction of the receiving groove (313) and the coupling groove (301) when the transfer screw (333) rotates.

[0060] Furthermore, the ultrasonic generating unit (305) is provided in the guide unit (303).

[0061] This ultrasonic generator (305) rotates together with the guide unit (303) to output ultrasonic waves so that the ultrasonic waves are transmitted through one of the multiple transmission windows (201) and penetrate the skin.

[0062] Additionally, the ultrasonic generating unit (305) moves along the guide groove (337) of the guide unit (303).

[0063] To explain the structure of the ultrasonic generating unit (305) in more detail, the ultrasonic generating unit (305) includes a coupling body (341) having a through hole (339), an ultrasonic forming head (345) provided on the upper part of the coupling body (341) and equipped with an ultrasonic oscillation element (343), and a guide projection (347) protruding from the lower part of the coupling body (341) and movably coupled to a guide groove (337).

[0064] Additionally, the ultrasonic generating unit (305) further includes a coupling member (349) whose outer surface is inserted into the through hole (339) and whose inner surface is inserted into the outside of the transfer screw (333).

[0065] First, the coupling body (341) is movably provided in the receiving groove (313), and a through hole (339) into which a coupling member (349) is inserted is formed on the inside.

[0066] The ultrasonic forming head (345) is provided on the upper part of the combined body (341), and an ultrasonic oscillating element (343) that outputs high-intensity focused ultrasound is provided on the upper side.

[0067] Additionally, the guide projection (347) is formed on the lower side of the coupling body (341), and when the coupling body (341) is located in the receiving groove (313), it is located on the inner side of the guide groove (337) and moves along the guide groove (337) when the transfer screw (333) rotates.

[0068] Next, the connecting member (349) is connected to the inside of the through hole (339), and its inner surface is movably connected to the outer surface of the transfer screw (333) to be described later.

[0069] Here, the connecting member (349) has a helical gear (351) formed on its inner surface to mesh with a gear portion (not shown) formed helically on the outer surface of the transfer screw (333), thereby allowing it to move in both directions along the transfer screw (333) when the transfer screw (333) rotates.

[0070] Additionally, the connecting member (349) has a step (353) formed protruding along the edge so that the length inserted into the through hole (339) is limited.

[0071] In this way, through the structure of the ultrasonic generating unit (305), one embodiment of the present invention can not only irradiate ultrasonic waves through one of the plurality of transmission windows (201) while rotating along the guide unit (303), but also, as the guide projection (347) is positioned in the guide groove (337), the ultrasonic generating unit (305) does not rotate together with the transfer screw (333) when the transfer screw (333) rotates, but moves along the guide groove (337), thereby allowing ultrasonic waves to penetrate a wider area of ​​the skin.

[0072] Meanwhile, a skin care device (10) according to one embodiment of the present invention further includes an ultrasonic transfer unit (355).

[0073] The ultrasonic transfer unit (355) includes the previously described drive motor (325) and transfer screw (333).

[0074] The drive motor (325) is provided in the motor coupling groove (327) formed at the end of the rotation guide (311), and is driven by receiving power to rotate the transfer screw (333).

[0075] And, one side of the transfer screw (333) is connected to the drive motor (325), and the other side is rotatably connected to the fixed groove (335) of the transfer guide (315).

[0076] The transfer screw (333) has a connecting member (349) connected to its outer side.

[0077] Additionally, the transfer screw (333) is formed spirally on its outer surface and has a gear portion (not shown) formed to mesh with the spiral gear (351) of the coupling member (349).

[0078] Thus, the transfer screw (333) can move the ultrasonic generating part (305) along the guide groove (337) when rotating.

[0079] As described above, according to one embodiment of the present invention, by irradiating ultrasound through one of the plurality of transmission windows (201) via the guide part (303) to control the penetration depth (D) of the ultrasound penetrating the skin, various procedures can be performed using a single device to suit the purpose of the procedure, thereby providing the effect of reducing costs and shortening the procedure time.

[0080] Although it has been described above that all components constituting an embodiment of the present invention are combined or operate as a single unit, the present invention is not necessarily limited to such an embodiment. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways to operate.

[0081] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments.
