Description

Skin treatment mouthpiece and skin treatment device using electric energy

The present invention relates to a skin treatment mouthpiece and a skin treatment apparatus using electrical energy.

Recently, various skin treatment devices for wrinkle removal, skin elasticity recovery and sebum removal have been developed. Wrinkle-free, taut, thick, dense, sagging skin looks more crisp and gives an attractive appearance.

Skin treatment devices that apply energy include a method of transmitting ultrasound to the skin tissue (HIFU type), a method of transmitting electromagnetic waves to the skin tissue (especially high frequency, RF type), and a method of irradiating laser light onto the skin tissue (Optical type).

The method of transmitting electromagnetic waves to skin tissue infiltrates single or plural Radio Frequency (RF) electrodes into the skin core, and uses electrical energy to remove damaged collagen, elastic fibers, etc. of the skin core and promote new formation. It also improves pigmentation of the skin, acne marks and wrinkles.

On the other hand, the skin treatment apparatus using the electric energy can use a direct current and an alternating current power according to the type of power source, and a lot of methods of using high frequency energy of high frequency band during alternating current have been developed. In addition, depending on the electrode, it is divided into a bipolar type (Bipolar type) that flows energy to the region near the electrode, and a monopolar type (Monopolar type) that transmits energy between the long distance to the skin tissue.

The bipolar method transfers electrical energy over a short distance between a plurality of electrodes, and has a limitation in that energy is concentrated in shallow and narrow areas.

In the mono-polar system, the first electrode unit 1 is used as a power terminal and the second electrode unit 2 provided as a ground terminal transfers electrical energy (see FIG. 1). . On the other hand, the first electrode unit 1 may be composed of a plurality of needle electrodes invading the dermis layer in order to deliver electrical energy to the deep skin. However, this is only an example of the first electrode unit 1, and the shape of the first electrode unit 1 is not limited to the shape of the plurality of needle electrodes.

Meanwhile, the retaining ligament connects the skin and the bone, and has a high moisture content, which can be used as an electric passage of the face. As shown in Fig. 3, the maintenance ligament is divided into several strands by branching the central strand from the bone tissue (inner side) to the skin tissue (outer side). When the support structure is weakened, thinned, and lost elasticity under the influence of aging, the aging phenomenon of the face part is exhibited. Thus, the oral mucosa is a location that can be similar to the skin and the electric flow originating from the bone as a solution, Figure 4 is a photographic view showing a portion that can be used as a ground for flowing electricity in close proximity to the skin ( See dashed area in FIG. 4).

Therefore, in the treatment of facial skin using electrical energy, the use of facial ligaments and vascular fibrous tissues as electrical passageways can actively prevent the sagging of skin due to aging by regenerating aging and atrophy of the ligaments and other structures described above. Can be.

However, a general monopolar skin treatment apparatus may contact the first electrode unit 1 with the target site and the second electrode unit 2 with any body part (eg, the back, the abdomen and the hip, etc., see FIG. 2). ), The distance between the first electrode unit 1 and the second electrode unit 2 is largely confined to the surface of the skin, and facial ligaments, blood vessels, and deep fiber tissues cannot be used as electrical passages. There is a problem.

The problem to be solved by the present invention is a monopolar skin treatment apparatus using a high-frequency wavelength band that can actively improve the facial sag effect due to skin aging by using a ligament, blood vessels, deep fiber tissue, etc. as an electric passage To provide.

Problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

Skin treatment mouse piece according to an aspect of the present invention for solving the above problems frame; And a ground electrode unit disposed in the frame, wherein the frame includes a first frame disposed at the front, a second frame extending rearward from one end of the first frame, and a rear at the other end of the first frame. And a third frame extending to the ground electrode unit, wherein the ground electrode unit is continuously and integrally formed in the first frame, the second frame, and the third frame.

When the frame is inserted into the oral cavity, at least one incisor is disposed in the first frame, at least one right molar is disposed in the second frame, and at least one left molar is disposed in the third frame. It can be characterized.

The ground electrode unit has at least a portion between the lip and the at least one incisor, at least a portion between the right buccal mucosa and the at least one right molar and at least a portion between the left buccal mucosa and the at least one left molar when inserted into the oral cavity. It may be characterized in that it is disposed in a portion.

The ground electrode unit may be in electrical interaction with an external power electrode unit such that an alternating current of a high frequency wavelength band flows.

The first frame may have a curvature formed forward, and at least a portion of the second frame and the third frame may have a large area portion that increases in height toward the rear of the first frame.

At least one of the first frame, the second frame, and the third frame may include a first cover disposed outside, a second cover disposed inside, and disposed between the first cover and the second cover. Including a seating portion, the ground electrode unit may be disposed on at least a portion of the outer surface of the first cover or may form at least a portion of the outer surface of the first cover.

The material of the frame is non-conductive, and the ground electrode unit is disposed in the middle of the outer surface of the first cover or the outer surface of the first cover so that the upper and lower portions of the outer surface of the first cover are exposed to the outside. Form the middle of

When the seating portion is inserted into the oral cavity, it may be characterized in that it is bitten by a plurality of upper teeth and a plurality of lower teeth.

The ground electrode unit may cover 95% or more of the outer surface of the first cover.

The seating portion may be formed with a recessed groove corresponding to the shape of the wearer's teeth.

Skin treatment apparatus according to an aspect of the present invention for solving the above problems is an electronic control unit; A skin treatment mouthpiece according to any one of claims 1 to 9 electrically connected with the electronic control unit; And a hand piece electrically connected to the electronic control unit, wherein the hand piece is supplied with power from the electronic control unit, and is electrically connected to the ground electrode unit of the skin treatment mouthpiece and an alternating current in a high frequency wavelength band. It may be characterized by including a power electrode unit for interacting.

In the skin treatment apparatus of the present invention, the power electrode unit is disposed outside (epidermal) with teeth (tooth) and facial skin interposed, and the ground electrode unit is disposed inside (oral cavity) and adjacent to each other. Therefore, the electrical energy efficiency is high, and the current easily flows through the ligaments and blood vessels and intercellular fibrous tissues located on the face, and the ligaments and blood vessels and deep intercellular fibrous tissues may be used as the electric passages.

Furthermore, since the alternating current between the power electrode unit and the ground electrode unit flows in a cyclic manner, when the alternating current flows from inside to outside, it flows through several strands branched from the central strand of the holding ligament. Electrical passages extending out of the core are created (see FIG. 3).

As a result, in the skin treatment apparatus of the present invention, the ligaments, blood vessels, and intercellular fibrous tissues can be utilized as electric passages, thereby effectively improving the facial sagging effect due to skin aging.

In addition, in the skin treatment apparatus of the present invention, in order to use high density of electrical energy, electrical energy of a high frequency wavelength band is used. By using the electric energy of the high frequency wavelength band, the heat generating portion may be concentrated in the portion where the power electrode unit is located on the skin of the subject, and there may be a risk of pain or burns.

In order to solve this problem, in the skin treatment mouthpiece of the present invention, the ground electrode unit is continuously and integrally formed along the outer surface of the frame, and the heat generating portion is concentrated by dispersing electric energy generated in the portion where the power electrode unit is located. (If the ground electrode unit is intermittently formed of a plurality of unit electrodes spaced apart from each other, only the unit electrode of the portion facing the power electrode unit is electrically activated and the heat generating portion thereof is intermittently formed.) Can be concentrated).

As a result, in the skin treatment apparatus of the present invention, it is possible to increase the therapeutic effect by using a high frequency wavelength band with a high energy density, and to prevent the concentration of the exothermic portion and increase the safety.

In addition, the mouthpiece of the present invention is inserted into the oral cavity, the ground of the mucous membrane is also electrically stimulated to create a new fibrous and elastic tissue to increase the tension and elasticity of the inner mucosa. Thus, since the treatment of the skin is maintained while the skin of the face is stretched (facial tightening and tensioning), the power electrode unit can be precisely contacted with the target point and the electrical energy can be efficiently delivered, thereby increasing the therapeutic effect. . Furthermore, tension in the upper structure that sags into the oral cavity can improve the external appearance of aged skin.

The operation panel 12 may be provided in the form of a touch screen. For example, the doctor may adjust the intensity of electric energy applied to the skin of the subject by clicking a button or an icon on the manipulation panel 12.

The hand piece 20 may be in contact with the patient's skin while being held in the doctor's hand. In this case, AC power may be applied from the hand piece 20 to generate electrical energy. Electrical energy is generated between the hand piece 20 and the mouth piece 30, and heat treatment can be carried out by concentrating heat on the deep skin part. The hand piece 20 may include a housing 21, a power electrode unit 22, a drive unit 23, and a support unit 24.

The housing 21 may be an exterior member that forms the exterior of the hand piece 20. The housing 21 can be manufactured by plastic injection or the like. However, the present invention is not limited thereto, and the housing 21 may be provided with various materials. The power electrode unit 22, the driving unit 23, and the support unit 24 may be disposed in the housing 21. In this case, the power electrode unit 22 is supported by the support unit 24 and can be arranged to be movable in the longitudinal direction (up and down direction).

When the power electrode unit 22 moves downward, the power electrode unit 22 may be exposed to the outside through a plurality of openings formed in the bottom surface of the first housing 21-1. Meanwhile, an upper portion of the power electrode unit 22 may be disposed in the second chamber b, and may be elastically supported by the support unit 24.

Meanwhile, when the pump 400 is added to the skin treatment apparatus 100 of the present invention, various fluids may be injected into the first chamber a of the first housing 21-1. For example, the first chamber (a) may be injected with cooling water, drugs, and the like to alleviate the rash and fever of the skin.

The driving unit 23 may be disposed in the second housing 21-2. In this case, the driving unit 23 may be connected to the support unit 24 at the boundary between the first housing 21-1 and the second housing 21-2 to drive the power electrode unit 22.

The power supply electrode unit 22 may be a "power supply terminal" for applying an alternating current of a high frequency wavelength band. To this end, the power electrode unit 22 and the ground electrode unit 32 may be electrically connected to a power supply unit (not shown) of the electronic control unit 10.

In the skin treatment apparatus 100 of the present invention, by using electrical energy of a high frequency wavelength band having a high energy density, the damaged collagen and aged skin tissue may be heated with high heat to improve a therapeutic effect (skin regeneration efficiency).

The current applied from the power electrode unit 22 may be refluxed in the ground electrode unit 32 described later. That is, the power electrode unit 22 and the ground electrode unit 32 may perform electrical interaction such that an alternating current of a high frequency wavelength band flows.

The power electrode unit 22 may include a plurality of needle electrodes 22-1. In this case, the power electrode unit 22 may be referred to as an "RF needle electrode unit". Hereinafter, although the power supply electrode unit 22 includes the some needle electrode 22-1, it demonstrates, for example, but the form of the power supply electrode unit 22 of this invention is not limited to this.

For example, as illustrated in FIG. 6 (1), the power electrode unit 22 may include a plurality of ball electrodes 22-2. In this case, the plurality of ball electrodes 22-2 may be rolled on the skin surface. In addition, since the plurality of ball electrodes 22-2 do not require vertical driving, the driving unit 23 may be omitted.

In addition, as shown in Fig. 6 (2), the power supply electrode unit 22 may include a flat plate electrode 22-3 having a pattern formed thereon. In this case, in order to form a pattern, the insulating layer 22-4 with the pattern portion open may be stacked on the flat electrode 22-3.

The lower end of the power electrode unit 22 may be a tip so as to penetrate the epidermal layer of the skin. Accordingly, when the power electrode unit 22 moves downward, electrical energy may be applied to the dermal layer of the deep skin part. On the other hand, the depth of the skin deep portion to which electric energy is applied can be determined by the stroke of the power supply electrode unit 22. The power electrode unit 22 may move upward and return after applying electrical energy to the dermal layer of the deep skin part.

Each of the plurality of needle electrodes 22-1 may have a needle shape extending in a vertical direction to form a length. A lower end of each of the plurality of needle electrodes 22-1 may be a tip.

The plurality of needle electrodes 22-1 may be arranged to form rows and columns on a plane perpendicular to the longitudinal direction (see FIG. 5). Therefore, the plurality of needle electrodes 22-1 may cover a wide range evenly.

The drive unit 23 can drive the power electrode unit 22 in the longitudinal direction (up and down direction). Various kinds of devices may be used for the drive unit 23. For example, the drive unit 23 may be a "step motor". However, the present invention is not limited thereto. For example, the driving unit 23 may be a “hydraulic or pneumatic cylinder” or the like.

The drive unit 23 may have a rod 23-1. The rod 23-1 may be connected to the support pad 24-2 of the support unit 24 to transmit the vertical driving force generated by the drive unit 23 to the support pad 24-2.

The support unit 24 may elastically support the power electrode unit 22 in the vertical direction. In addition, the support unit 24 may receive the driving force of the driving unit 23 to operate the power electrode unit 22. The support unit 24 may include an elastic member 24-1 and a support pad 24-2.

The elastic member 24-1 of the support unit 24 may be a "sterile spiral spring". The upper end of the elastic member 24-1 is in contact with the support pad 24-2, and the lower end of the elastic member 24-1 is at the bottom surface of the second chamber b of the first housing 22-1. Can be contacted. Therefore, the elastic member 24-1 may elastically support the support pad 24-2 in the vertical direction. On the other hand, as described above, the support pad 24-2 is connected (coupled) to the upper end of the power electrode unit 22. As a result, the power electrode unit 22 can be elastically supported in the vertical direction by the support unit 24.

Mouthpiece 30 may be inserted into the mouth of a patient. The AC power of the high frequency wavelength band of the hand piece 20 may be transmitted to the mouthpiece 30 through the skin deep portion. The mouthpiece 30 may include a frame 31 and a ground electrode unit 32.

The frame 31 may be an exterior member that forms the appearance of the mouthpiece 30. The material of the frame 31 may be non-conductive (eg, synthetic resin such as rubber and plastic). This is to prevent high frequency electric energy from being applied to the dental implant of the subject.

The frame 31 may include a first frame 31-1, a second frame 31-2, and a third frame 31-3. The first frame 31-1, the second frame 31-2, and the third frame 31-3 may be integrally formed.

At least a portion of the second frame 31-2 and the third frame 31-3 may have a large area portion that increases in height toward the rear. As a result, the treatment can proceed while the skin of the face remains taut.

At least one of the first frame 31-1, the second frame 31-2, and the third frame 31-3 may include a first cover 31-4 disposed at an outer side thereof, and a second frame disposed at an inner side thereof. The cover 31-5 may include a seating part 31-6 disposed between the first cover 31-4 and the second cover 31-5.

That is, the first cover 31-4 of the first frame 31-1 may be disposed in front of the second cover 31-5 of the first frame 31-1, and the second frame 31. The first cover 31-4 of -2) may be disposed on the right side of the second cover 31-5 of the second frame 31-2, and the first cover of the third frame 31-3. 31-4 may be disposed on the left side of the second cover 31-5 of the third frame 31-3.

Teeth and a plurality of lower teeth may be stably fixed by the seating portion 31-6. To this end, the seating portion 31-6 may be formed with a recessed groove corresponding to the wearer's teeth (type of teeth).

The ground electrode unit 32 may be a "ground end" in which an alternating current of a high frequency wavelength band transmitted to the skin is refluxed. That is, the ground electrode unit 32 may perform electromagnetic interaction with the power electrode unit 22 so that an alternating current of a high frequency wavelength band flows. To this end, the ground electrode unit 32 may be electrically connected to a power supply unit (not shown) of the electronic control unit 10.

On the other hand, the ground electrode unit 32 is used to prevent the alternating current generated by electrical interaction with the power electrode unit 22 from being concentrated on a specific minute portion of the wearer's face (the skin treatment apparatus of the present invention uses high frequency energy). Since the user can feel burns or pain when the electrical energy is concentrated), the first frame 31-1 and the second frame 31-2 and the third frame 31-3 are continuous. It may be formed integrally and disposed.

The ground electrode unit 32 has at least a portion between the lip and the at least one incisor and at least a portion between the right buccal mucosa and the at least one right molars and a portion between the left buccal mucosa and the at least one left molars upon insertion into the oral cavity. Can be placed in.

That is, the ground electrode unit 32 is integrally formed in a wide part in the oral cavity and may be continuously distributed. As a result, in the skin treatment apparatus 100 of the present invention, it is possible to prevent the electrical energy from concentrating on a specific microregion.

On the other hand, the ground electrode unit 32 should be disposed as close as possible for electrical interaction with the power electrode unit 22. To this end, the ground electrode unit 32 may be disposed on the outer surface of the frame 31 or form the outer surface of the frame 31. That is, the ground electrode unit 32 may be disposed on the outer surface of the first cover 31-4 or may form the outer surface of the first cover 31-4.

On the other hand, the ground electrode unit 32 is disposed in the middle of the outer surface of the first cover 31-4 or the first cover so that the upper and lower portions of the outer surface of the first cover 31-4 are exposed to the outside. 31-4) can form the middle of the outer surface. That is, the height of the first cover 31-4 may be higher than the height of the ground electrode unit 32, and the upper and lower portions of the first cover 31-4 may not overlap the ground electrode unit 32.

This is to prevent the portion in which the dental implant of the subject is located from overlapping with the ground electrode unit 32, thereby preventing the high-frequency electrical energy from being supplied to the dental implant.

Meanwhile, the ground electrode unit 32 may cover 95% or more of the outer surface of the first cover 31-4. The large area of the ground electrode unit 32 is to cover all the ligaments, blood vessels and intercellular fibrous tissues and the like shown in Figs. 3 and 4, and to utilize them as electric passages.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
