Description

Technical Field

[0001] The invention relates to a needle tip installed on a skin management device and the skin management device. Background Art

[0002] Skin care devices are currently being developed to achieve wrinkle removal, restoration of skin elasticity, and removal of sebum, etc. Wrinkle-free, tight, thick and dense skin without sagging makes a person look younger and contributes to an attractive appearance.

[0003] There are many types of skin care devices, such as a method of transmitting ultrasonic waves to skin tissue (HIFU type), a method of transmitting high frequency to skin tissue (RF type), and a method of irradiating laser light to skin tissue (Optical type).

[0004] The device that transmits high frequency to the skin tissue uses a handpiece equipped with a single or multiple radio frequency (RF) needle electrodes to penetrate the RF needle electrodes into the deep part of the skin (e.g., dermis layer) of the target location (e.g., face), and uses the heat energy generated by the high frequency to remove the damaged collagen and elastic fibers in the deep part of the skin at the target location, and promote the formation of new collagen and elastic fibers. Furthermore, this skin management device improves skin pigmentation, acne marks, wrinkles, etc.

[0005] In this case, in a single or multiple RF needle electrodes, if the cutting edge of the end is exposed and the remaining portion is coated with an insulating material, high frequency can be concentratedly transmitted deep into the skin (refer to Figure 1 , Figure 1 (a) is the case where the needle electrode is not coated with insulating material. Figure 1 (b) is the case where the needle electrode is coated with an insulating material).

[0006] This skin management device is divided into a bipolar type in which a plurality of radio frequency needle electrodes have two polarities and a monopolar type in which a plurality of radio frequency needle electrodes have one polarity and are separately provided with a ground electrode.

[0007] In the bipolar type, the high frequency applied from the first polarity radio frequency needle electrode flows back to the second polarity radio frequency needle electrode. Therefore, since the high frequency flows between the plurality of radio frequency needle electrodes, the high frequency can be applied locally and concentratedly.

[0008] In the monopolar type, the high frequency applied from the RF needle electrode flows back to the ground electrode arranged at a non-target site (eg, back). Therefore, since the high frequency flows in a wide range, the high frequency can also affect the surroundings of the target site.

[0009] In addition, in the process of regenerating the skin using a radio frequency needle electrode, a drug is applied to relieve the pain caused by the radio frequency needle electrode penetrating deep into the skin and to treat minor wounds.

[0010] However, general skin care devices are not equipped with an applicator for automatically applying a drug, or even if equipped with such an applicator, there are problems that the size of the handpiece becomes large or the drug cannot be deeply injected into the inside of the invasion site. Summary of the invention

[0043] Below, the “vertical direction” can be Figure 4 The vertical direction shown in the figure can be used interchangeably with the “upper and lower directions”. That is, “one side in the vertical direction” can be the upper side, and “the other side in the vertical direction” can be the lower side.

[0044] The skin management device 1000 of the present invention may include: a main body 100, a display module 200, an operation module 300, an electronic control module (not shown), a cable 400, a handpiece 500, a needle tip 600, a driving module 700 and a power module 800.

[0045] The main body 100 may be equipped with a display module 200 and an operation module 300. The display module 200 may be made in the form of a panel to visually provide various information to the doctor performing the skin management operation. Therefore, as an example, the high-frequency output or impedance applied to the dermis at the current target location may be displayed in the form of a curve graph on the display module 200. In addition, the display module 200 may display the current operating mode of the skin management device 1000 of the present invention. In addition, the display module 200 may display biological information deep in the skin tissue at the target location.

[0046] The operation module 300 may be provided in a button form on the outer side of the body 100. The doctor may turn on / off the skin management device 1000 or select the operation mode of the skin management device 1000 through the operation module 300, and may change the output of the high frequency applied to the target site.

[0047] In addition, when the display module 200 is provided in the form of a touch screen, at least a part of the operation module 300 may be omitted. In this case, the doctor may operate the skin management device 1000 by touching the menu displayed on the screen of the display module 200 .

[0048] The electronic control module (Electric Control Module) may be built into the main body 100 and may electronically control the components of the skin management device 1000. To this end, the electronic control module may be electrically connected to the driving module 700 and the power module 800 via the cable 400. That is, the electronic control module may apply a control signal corresponding to the operation signal to the driving module 700 and the power module 800 according to the doctor's operation signal.

[0049] As an example, the driving cycle of the driving module 700 can be controlled by a control signal of the electronic control module. As a result, the reciprocating driving cycle of the needle unit 620 of the needle tip 600 can be controlled.

[0050] Furthermore, the output of the power module 800 can be controlled by the control signal of the electronic control module. As a result, the wavelength, direction, and intensity of the current applied to one or more needle electrodes 622 of the needle unit 620 of the needle tip 600 are changed, thereby controlling the output of the high frequency applied to the target location.

[0051] The cable 400 may perform a function such as a conductive line that electrically connects the electronic control module and the driving module 700 or electrically connects the electronic control module and the power module 800. To this end, the cable 400 may extend from the main body 100 to one side, thereby connecting the main body 100 and the handpiece 500. The cable 400 may have a plurality of wires built therein so as to form respective channels according to the types of electronic signals, and the outer sheath of the cable 400 may insulate the bundle of wires covering the various channels.

[0052] The handpiece 500 is a part held by the doctor, and the doctor can move the handpiece 500 while contacting the handpiece 500 with the subject's skin to change the target location (for example, a part of the face). The handpiece 500 can be arranged on the cable 400 and can be located at the end of the direction in which the cable 400 extends.

[0053] The hand piece 500 may be built with a driving module 700 and a power module 800. Therefore, the cable 400 may electrically connect each of the driving module 700 and the power module 800 built in the hand piece 500 to the electronic control module built in the main body 100. The end of the hand piece 500 may be mounted with a needle tip 600. In this case, the needle tip 600 may be mounted on the end of the hand piece 500 in a replaceable manner like a box form.

[0054] The outside of the handpiece 500 may be equipped with a first conductive component 501 for electrically connecting the needle unit 620 of the needle tip 600 and the power module 800, and a second conductive component 502 for electrically connecting the power module 800 and the cable 400 by docking with the cable connector 503. In this case, the first conductive component 501 and the second conductive component 502 may be manufactured in a film form. As an example, the first conductive component 501 and the second conductive component 502 may be a flexible printed circuit board (FPCB: Flexible printed circuit board). As described below, since the needle unit 620 of the needle tip 600 moves back and forth (drives), in order not to interfere with the conductive wire during the back and forth movement of the needle unit 620 of the needle tip 600, the conductive wire of the needle unit 620 of the needle tip 600 and the power module 800 and the conductive wire of the power module 800 and the cable 400 are equipped on the outside of the handpiece 500.

[0055] The needle tip 600 may be a component for applying high frequency to the deep part of the skin at the target location. The needle tip 600 may be detachably mounted on the end of the handpiece 500. That is, the needle tip 600 of the present invention may be manufactured in the form of a box so that it can be replaced.

The lower side of the housing 610 may be open, and the lower end of the housing 610 may be arranged on the surface of the skin of the target site. In this case, the lower part of the housing 610 may have an inner space s formed by the needle unit 620 and the side wall of the housing 610 and the skin of the target site.

[0058] The volume of the internal space s of the housing 610 may vary depending on the vertical position of the needle unit 620. That is, the volume of the internal space s of the housing 610 has a maximum value at the top dead center of the needle unit 620 (refer to Figure 8 (a)), has a minimum value at the bottom dead center of the needle unit 620 (refer to Figure 8 (b)).

[0059] In addition, when the needle unit 620 descends, one or more needle electrodes 622 of the needle unit 620 can penetrate the skin of the target site through the opening at the bottom of the housing 610 .

The one or more guide members 613 formed on the first shell 611 and the second shell 612 may be in the form of holes extending from the inner circumference of the side walls of the first shell 611 and the second shell 612 to the outer circumference. The one or more guide members 613 formed on the first shell 611 and the second shell 612 may guide the vertical movement of the needle unit 620. Furthermore, the vertical stroke of the needle unit 620 may be determined by the one or more guide members 613 formed on the first shell 611 and the second shell 612.

[0062] The first housing 611 can be detachably mounted on the end of the handpiece 500. To this end, one or more mounting grooves 614 can be formed on the upper portion of the first housing 611. That is, the mounting protrusion formed on the housing of the handpiece 500 is docked with the mounting groove 614 of the first housing 611, so that the handpiece 500 and the needle tip 600 can be mounted.

[0063] The second housing 612 may contain a needle unit 620. The upper portion of the hollow portion of the second housing 612 may be closed by the needle unit 620. Therefore, the lower portion of the second housing 612 may be formed with an internal space s that is open at the lower portion. The lower open portion of the internal space s of the second housing 612 may be closed by the surface (epidermis) of the skin at the target site, and one or more needle electrodes 622 of the needle unit 620 may be inserted into the deep portion (dermis) of the skin at the target site through the lower open portion of the internal space s of the second housing 612.

[0064] The needle unit 620 can be arranged inside the housing 610. The needle unit 620 can move back and forth in the vertical direction by the driving module 700. The needle unit 620 can repeatedly (periodically) invade the skin of the target location by moving back and forth in the vertical direction. Furthermore, the needle unit 620 can generate high frequency deep in the skin of the target location, and remove damaged collagen, elastic fibers, etc. by the heat energy generated by the high frequency. The collagen and elastic fibers removed by the needle unit 620 regenerate (newly formed) over time, thereby increasing skin elasticity (forming wrinkle-free, thick, dense and non-loose skin).

[0065] The needle unit 620 may include a housing 621 , one or more needle electrodes 622 , a support member 623 , a coating pad 624 , a pressurizing member 625 , a gasket pad 626 , and a connecting rod 627 .

[0067] The shell 621 may be arranged inside the housing 610. And the shell 621 may be moved in the vertical direction by the driving force of the driving module 700. One or more needle electrodes 622, a support member 623, a gasket pad 626 and a connecting rod 627 may be arranged inside the shell 621.

The first housing 621-1 may be arranged on the upper side, the second housing 621-2 may be arranged on the lower side, and the first housing 621-1 and the second housing 621-2 may be combined by assembly.

[0070] One or more blocking members 621-3 formed protruding outward may be formed on the outer peripheral surface of the first housing 621-1. The blocking members 621-3 of the first housing 621-1 may be arranged respectively on one or more guide members 613 formed on the first shell 611 and the second shell 612. The reciprocating movement of the needle unit 620 in the vertical direction may be blocked by one or more blocking members 621-3 of the first housing 621-1. That is, when the needle unit 620 moves upward, one or more blocking members 621-3 of the first housing 621-1 are stuck on the top surface of one or more guide members 613 formed on the first shell 611 and the second shell 612, so that the upward movement of the needle unit 620 can be blocked. And, when the needle unit 620 moves downward, one or more blocking members 621-3 of the first housing 621-1 are stuck on the bottom surface of one or more guide members 613 formed on the first shell 611 and the second shell 612, so that the downward movement of the needle unit 620 can be blocked.

[0073] One or more needle electrodes 622 can penetrate into the deep part of the skin of the target location and apply high frequency to the deep part of the skin of the target location. To this end, one or more needle electrodes 622 can be electrically connected to the power module 800 to receive power. One or more needle electrodes 622 can be electrically connected to the power module 800 via the first conductive component 501 described above.

[0074] One or more needle electrodes 622 can be moved back and forth in the vertical direction by the driving force of the driving module 700. At the bottom dead point of the needle unit 620, the lower end of one or more needle electrodes 622 can be arranged in the deep part of the skin of the target location, and at the top dead point of the needle unit 620, the lower end of one or more needle electrodes 622 can be arranged on the upper side of the skin surface of the target location. Therefore, one or more needle electrodes 622 can repeatedly penetrate into the deep part of the skin of the target location. In this case, the penetration depth of one or more needle electrodes 622 can be about 2.1 mm.

[0075] The one or more needle electrodes 622 may be a bipolar type electrode unit in which a plurality of electrodes have two polarities and generate high frequencies between adjacent electrodes, or may be a monopolar type electrode unit in which a plurality of electrodes all have the same polarity.

[0076] In the case where one or more needle electrodes 622 are of a monopolar type, the skin management device 1000 of the present invention may be further equipped with a ground electrode module (not shown) for returning the high frequency generated from one or more needle electrodes 622 .

[0077] One or more needle electrodes 622 may be supported by a support member 623. One or more needle electrodes 622 may extend downward from the support member 623. In this case, one or more needle electrodes 622 may extend downward through the bottom of the housing 621 and the coating pad 624. A tip may be formed at the lower end of one or more needle electrodes 622. Except for the tip portion and the vicinity thereof, one or more needle electrodes 622 may be insulated and coated. In this case, high frequency is generated only at the tip portion and the vicinity thereof of one or more needle electrodes 622, so that heat energy can be concentrated only in the deep part of the target site (refer to Figure 1 (b)).

[0078] The coating pad 624 may be arranged at the center of the bottom of the housing 621. The coating pad 624 may be in the form of a flat plate. A drug may be coated on the bottom of the coating pad 624. The drug may perform the function of relieving pain caused by the invasion of one or more needle electrodes 622 or heat energy generated by high frequency. Furthermore, the drug may restore the deep part of the skin at the target location to improve the skin regeneration efficiency (improve the surgical effect).

[0079] The coating pad 624 can be moved in the vertical direction by the driving force of the driving module 700. At the bottom dead center of the needle unit 620, the bottom of the coating pad 624 can contact the surface of the target site, and at the top dead center of the needle unit 620, the bottom of the coating pad 624 can be arranged to be separated from the surface of the target site and upward. As a result, the coating pad 624 can repeatedly (periodically) contact the surface of the target site, and the drug on the coating pad 624 can be vibrated and coated on the surface of the target site.

[0080] In addition, as described above, at the bottom dead center of the needle unit 620, the volume of the internal space s of the housing 610 is reduced, so that a positive pressure can be formed in the internal space s of the housing 610. Due to the positive pressure of the internal space s of the housing 610, the drug applied to the skin surface of the target site can be injected into the deep part of the skin of the target site along the channel of the skin of the target site formed by one or more needle electrodes 622.

[0081] The coating pad 624 may be made of silicone material. Due to the characteristics of silicone material, it can adhere to the surface of the skin at the target site, thereby improving the coating efficiency of the drug.

[0082] The pressurizing member 625 may be disposed at an edge position of the bottom of the housing 621. The pressurizing member 625 may be disposed along the periphery of the coating pad 624. The pressurizing member 625 may be substantially in the form of a ring.

[0083] The pressurizing component 625 can be moved in the vertical direction by the driving force of the driving module 700. The pressurizing component 625 can pressurize the surface of the skin of the target location downward at the bottom dead center of the needle unit 620. To this end, the lower end of the pressurizing component 625 can be located below the lower end of the housing 610 at the bottom dead center of the needle unit 620.

[0084] When one or more needle electrodes 622 penetrate into the skin of the target site, the pressurizing member 625 can expand the skin surface of the target site to flatten the skin surface of the target site. Therefore, the penetration depth of one or more needle electrodes 622 can be uniform, and as a result, one or more needle electrodes 622 apply high frequency at an accurate depth that meets the design conditions, thereby improving the surgical effect.

[0085] The pressurizing member 625 may have a structure that facilitates the surface of the skin at the target location to be expanded. As an example, the lower portion of the pressurizing member 625 may be formed to be inclined outward toward the lower side. In addition, a curved surface convex toward the lower side may be formed at the lower end of the pressurizing member 625. As a result, the contact area between the pressurizing member 625 and the skin surface at the target location is reduced, thereby increasing the pressurizing force.

[0086] In addition, the pressurizing member 625 may include one or more recessed portions 625-1 formed concavely from the bottom to the top. The one or more recessed portions 625-1 of the pressurizing member 625 may be in the form of holes extending from the outer circumference to the inner circumference of the pressurizing member 625. The recessed portions 625-1 of the pressurizing member 625 may be arranged spaced apart from each other along the circumferential direction of the pressurizing member 625. The recessed portions 625-1 of the pressurizing member 625 may prevent excessive positive pressure from being formed in the internal space of the pressurizing member 625, thereby preventing the surface of the skin at the target location from being deformed.

[0087] The connecting rod 627 may be disposed on the upper side of the support member 623. The connecting rod 627 may be moved in a vertical direction by the driving force of the driving module 700. The connecting rod 627 may be connected to the driving module 700 and the support member 623, thereby performing the function of transmitting the driving force of the driving module 700 to the support member 623.

[0088] In addition, in order to prevent the wear of the bottom of the connecting rod 627 and the top of the supporting member 623, and to evenly distribute the driving force transmitted by the connecting rod 627 to the top of the supporting member 623, a gasket 626 can be added. The gasket 626 can be in the form of a flat plate, and the material of the gasket 626 can include silicone and elastic material. The gasket 626 can be arranged between the bottom of the connecting rod 627 and the top of the supporting member 623.

[0089] One or more sealing components 630 may be arranged between the housing 610 and the housing 621 of the needle unit 620. The sealing component 630 may be in a ring shape. The outer peripheral surface of the one or more sealing components 630 may contact the inner peripheral surface of the housing 610, and the inner peripheral surface of the one or more sealing components 630 may contact the outer peripheral surface of the housing 621 of the needle unit 620. As a result, the one or more sealing components 630 may close the space between the housing 610 and the housing 621 of the needle unit in the vertical direction. That is, the sealing component 630 may improve the airtightness of the internal space s of the housing 610.

[0090] In summary, the one or more sealing components 630 may be referred to as an O-ring.

[0091] In order to stably fix the one or more sealing members 630, one or more grooves for accommodating each of the one or more sealing members 630 may be formed on the outer circumferential surface of the housing 621. There may be a plurality of the one or more sealing members 630, and the plurality of sealing members 630 may be arranged to be spaced apart from each other in the vertical direction.

[0092] One or more sealing members 630 can prevent the drug from leaking into the space between the housing 610 and the shell 621 of the needle unit 620. In addition, the one or more sealing members 630 improve the airtightness of the internal space s of the housing 610, thereby increasing the positive pressure applied to the internal space s of the housing 610 at the bottom dead center of the needle unit 620. As a result, the amount of the drug injected into the deep part of the skin of the target site and the injection depth can be increased.

[0093] Oil made of silicone material may be applied to the contact portion between one or more sealing components 630 and the inner circumferential surface of the housing 610. The oil can improve the efficiency of the functions of the one or more sealing components 630 through lubrication and sealing, and can also solidify during washing to prevent the reuse of the replaceable needle tip 600 (solidified oil generates friction when the needle unit moves back and forth).

[0094] The driving module 700 may be built into the handpiece 500, and may provide a driving force for reciprocating the needle unit 620 of the needle tip 600. Various types of driving devices may be applied to the driving device of the driving module 700. As an example, the driving module 700 may include a pneumatic cylinder or a linear motor.

[0095] The power module 800 may be built into the hand piece 500, and may provide power to one or more needle electrodes 622 of the needle unit 620 of the needle tip 600. In this case, the power module 800 may provide DC power or AC power to the one or more needle electrodes 622. The power module 800 may be electrically connected to the one or more needle electrodes 622 of the needle unit 620 of the needle tip 600 via the first conductive component 501, and may be electrically connected to the cable 400 via the second conductive component 502.

[0096] Therefore, the power module 800 can receive the control signal of the electronic control module through the cable 400 and apply the corresponding power to one or more needle electrodes 622 .
