Detailed Embodiments

[0037] The present invention can be implemented with various modifications. Hereinafter, specific embodiments are shown in the drawings and will be described in detail. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that the present invention includes all modifications, equivalents, and alternatives within the spirit and technical scope of the present invention.

[0038] When explaining each drawing, similar reference numerals are used for similar components. When explaining the present invention, when it is considered that a detailed description of related well-known technologies may make the gist of the present invention unclear, the detailed description thereof is omitted.

[0039] The present invention can utilize various stimuli to treat the skin surface and subcutaneous tissue.

[0040] Such as Figures 1 to 3As shown, the microwave-based treatment device according to the present invention is a device for treating the skin and subcutaneous tissues, and is characterized by including: an electrode 1 that generates microwaves by being supplied with power from a power source; a cavity 2 that forms a hollow cylindrical shape, and one end of the electrode is disposed to face the skin and be exposed in the middle of the cavity; a gas supply source 3 that supplies gas to the space between the electrode and the inner wall of the cavity. Through the microwave frequency electromagnetic field of the electrode, the supplied gas forms a low-temperature ionized gas, and the ionized gas faces the skin, so that the skin is exposed to the ionized gas.

[0041] The electrode 1 is supplied with electricity from a power supply 1e and generates an electromagnetic field with a frequency that can stimulate and activate the skin or subcutaneous tissues. The electrode 1 is manufactured in a rod shape with a pointed end on one side.

[0042] The material of the electrode can be one of various metals, can be in the shape of a rigid tube, has a length longer than the length of the cavity 2, and the tip is exposed to the end of the cavity.

[0043] The electrode 1 is connected to a ground 1g.

[0044] In addition, as Figures 1 to 3 shown, the electrode 1 is located on the center line in the center of the cavity 2, one end protrudes to the open end of the cavity, and the other end protrudes through the other end of the cavity (refer to Figure 1 ) or is fixed to the closed end on one side of the cavity. (Refer to Figure 2 and Figure 3 )

[0045] The electrode 1 is connected to a microwave power supply 1e through a conductor 1c including a wire. The conductor 1c is connected to the electrode through an opening 2o on the side wall of the cavity 2, and an insulator 2i is provided on the opening 2o for electrical insulation.

[0046] The cavity 2 is manufactured in a tubular form with an open shape at at least one end.

[0047] The cavity 2 is preferably made of metal. Considering that there may be electric leakage due to the electricity supplied by the power source, it is preferably grounded 2g.

[0048] The size of the internal space of the cavity 2 is formed to be larger than the diameter of the electrode 1, so that the gas flowing into the cavity 2 can flow smoothly.

[0049] The open end of the cavity 2 faces the skin 100, and the distance D between the open end of the cavity and the skin needs to be maintained.

[0050] The skin treatment device assembly composed of the above-mentioned cavity 2 and electrode 1 can be used in a handheld manner. In a preferred embodiment, the connecting part between the microwave power supply 1e and the gas supply source 3 is made of a flexible material so that the assembly can move easily along the skin.

[0051] That is, the conductor between the power supply and the electrode, and the gas supply pipe connecting the gas supply source 3 and the cavity need to be flexible.

[0052] The above-mentioned gas supply source 3 is used to supply ionized gas, which is ionized by the microwave generated by the above-mentioned electrode. As Figure 1 shown, a gas supply pipe is connected between the nozzles 3n combined with one side of the cavity. The gas supply pipe is formed of a soft material so that it can move freely in the cavity.

[0053] A valve 3v is provided on one side of the above-mentioned nozzle, so that the flow rate of the gas supplied to the nozzle can be controlled. When the above-mentioned valve 3v is opened, the gas flows into the internal space of the cavity.

[0054] The flow rate of the gas flowing into the internal space of the above-mentioned cavity is preferably 0.1 - 20 m / s. The gas supplied into the cavity is discharged to the open end of the cavity to stimulate the skin.

[0055] The electricity supplied from the above-mentioned power supply applies electricity with a microwave frequency of 1 - 50 GHz to the electrode 1. The microwave electricity level can be constant, can be periodic, or can be modulated within the range of 10 - 100 W.

[0056] As described above, the internal space of the above-mentioned cavity 2 plays a role of microwave resonance. That is, a high-intensity electromagnetic field is formed at the protruding end of the electrode 1, thereby inducing electrical breakdown and ionization around the electrode end.

[0057] The gas ionized by the gas flow between the above-mentioned cavity 2 and the electrode 1 generates a low-frequency plasma streamer. Although the gas is highly ionized, it is not heated, so the gas temperature is as low as 50 ± 5 °C or below.

[0058] The area reached by the ionized gas becomes larger as the gas flow rate and the microwave power increase. When the gas flow rate increases, the gas temperature decreases. The ionized gas flows and attenuates at a distance of 2 - 3 cm below the electrode end.

[0059] The device of the present invention is configured at a distance D1 from the skin, which is lower than the length of the luminous part of the gas flow.

[0060] The range of D1 is 5 to 30 mm. In a preferred embodiment, the center of the cavity 2 is configured to be perpendicular to the surface of the object to be treated, and the skin and the underlying tissue (100s) within the footprint of the ionized gas flow on the skin are treated simultaneously by the following factors.

[0061] That is, in the ionized gas flow, ozone, atomic oxygen, and hydroxyl radicals are formed to attack bacteria on the skin to disinfect the skin. The ionized gas has a bactericidal effect and emits ultraviolet light in the known wavelength range of 430 to 500 nm.

[0062] The ionized plasma streamers between the electrode 1 and the tissue 200 initiate low-current and low-frequency discharges for activating the nerves in the lower tissue 100s of the treatment area, improving blood circulation, and muscle tension. All discharge currents are less than 5 microamperes of the weak pain level, so the plasma streamers induce a slight "tingling" sensation.

[0063] Figure 2 It is a structural diagram of other examples. In other embodiments, an auxiliary gas supply source 4 can also be configured.

[0064] The above-mentioned auxiliary gas supply source 4 is a mechanism for supplying gas together with the above-mentioned gas supply source 3. The nozzle 4n can be arranged at a position adjacent to the open end of the cavity 2, and the nozzle outlet faces the cavity central axis in the area between the electrode 1 and the skin 100, towards the intersection of the skin and the cavity central axis.

[0065] A valve 4v is provided on the gas supply pipe between the above-mentioned nozzle 4n and the auxiliary gas supply source 4 to control the flow of compressed gas.

[0066] In addition, the present invention can also include light sources 5, 5'.

[0067] As Figure 3 shown, the above-mentioned light sources 5, 5' are arranged on the cavity 2 by the light source holder 5h, or arranged at the closed end of the cavity 2.

[0068] The light sources 5, 5' can be lamps, lasers, optical fibers, or any other known light sources, and the light emitted by the light sources 5, 5' irradiates the skin.

[0069] In a preferred embodiment, the light irradiated by the light source forms a light cursor towards the intersection of the cavity central axis and the skin.

[0070] As Figure 3 shown, for the light source 5' among the two light sources 5, 5' arranged at the closed end of the cavity, a light-transmitting glass 5g' can be arranged at the cavity end, and a lens 5l' can be arranged between the light source 5' and the light-transmitting glass.

[0071] That is, the material of the closed end of the cavity 2 is transparent to light and impermeable to microwave frequencies. By using the light-transmitting glass 5g' to block the end of the cavity, electromagnetic fields and compressed gas leakage can be prevented. The light-transmitting glass can be covered by a conductive protective band 5e' such as a metal mesh or a transparent conductive thin film like SnO2 that is grounded or connected to the cavity.

[0072] The electrode 1 can be electrically connected to the protective band 5e'. The light source 5' emits light that can pass through the lens (5l', also known as the 'optical system'), and a light beam parallel to the central axis of the cavity can be formed.

[0073] In addition, the above light source 5' can be arranged inside the cylinder formed by the mirror 5r'.

[0074] In addition, according to the treatment and disposal of the present invention, such as Figure 4 、 5 As shown, the electrode 1 and the cavity 2 can be arranged on the robot platform 8, and the robot platform 8 is installed on the component base 7.

[0075] Such as Figure 4 、 5 As shown, the above component base 7 forms a cylindrical shape with one open side, and a human body can be placed inside. The above robot platform 8 is arranged on the open side of the component base. The treatment instrument holder 6 is arranged on the above robot platform 8, and the above cavity 2 is arranged on the treatment instrument holder 6. Thus, the treatment instrument holder can not only move up, down, left, and right, but can of course also be inclined and supported by the component base.

[0076] That is, the above robot platform 8 can at least control the movement of the component along two-dimensional directions.

[0077] That is, the robot platform 8 can move in three dimensions along the X, Y, and Z directions, and the treatment instrument holder 6 itself has the function of tilting the cavity 2 up, down, left, and right.

[0078] The treatment instrument holder 6 is arranged on the arc track 8r of the above robot platform 8. The arc track 8r crosses the patient's body part and moves the treatment instrument holder 6 along an arc trajectory (direction Y). Through electric sliding, the treatment instrument holder can move across around the body.

[0079] In addition, a lifting and sliding mechanism 8e is arranged at the end of the above arc track. The lifting and sliding mechanism 8e moves along the up and down direction (direction X) of each patient's body part. Thus, the treatment instrument holder rises and falls together with the lifting of the arc track 8r, and the treatment instrument including the cavity can move up, down, left, and right.

[0080] In addition, the above-mentioned treatment instrument holder 6 is designed to horizontally move the cavity 2, thereby maintaining a necessary distance between the cavity 2 and the skin of the patient's body part. The electrically controllable tilting mechanism of the cavity 2 can keep the discharge port of the cavity 2 perpendicular to the skin surface of the body part.

[0081] Next, the operation of the microwave-utilizing treatment device of the present invention described above will be additionally described.

[0082] Compressed gas from the above-mentioned gas supply source 3 is transferred to the cavity 2 through the fluid passage and the valve 3v.

[0083] The gas flow rate supplied to the cavity is 0.1 - 20 m / s, and the gas is discharged through the open end of the cavity 2.

[0084] The microwave frequency (1 - 50 GHz) power supply 1e is applied to the electrode 1 through the conductor 1c. The microwave power level can be constant or periodic and can be modulated within the range of 10 - 100 W.

[0085] The internal space of the cavity 2 is of a degree that can cause microwave resonance. A high-strength electromagnetic field intensity is formed at the protruding end of the electrode 1, inducing electrical breakdown and ionization of the gas around the electrode end. Due to the gas flow, ionized airflows generate low-frequency plasma streamers.

[0086] The gas is highly ionized but not heated, so the gas temperature is low, approximately 50 degrees. The size (action area) of the ionized airflows increases with the increase of the gas flow rate and the microwave power.

[0087] When the gas flow rate increases, the gas temperature decreases, and the luminous ionized airflows attenuate at a distance of 2 - 3 cm below the electrode end.

[0088] The device is set at a position far from the skin D1, which is lower than the length of the luminous part of the ionized airflows. The range of D1 is 5 - 30 mm. In a preferred embodiment, the central axis of the cavity 2 is arranged perpendicular to the surface to be treated, and the skin and the underlying tissue 100s within the footprint of the ionized airflows on the skin are simultaneously treated by the following factors.

[0089] That is, ozone, atomic oxygen, and hydroxyl radicals are generated through the ionized airflows to attack bacteria on the skin and disinfect the skin. The ionized gas emits ultraviolet rays in the wavelength range of 430 - 500 nm, which is known to have a bactericidal effect.

[0090] The ionized plasma streamers between the electrode 1 and the skin initiate low current and low frequency discharges that activate nerves in the underlying tissue 100s, improve blood circulation, and muscle tone. All discharge currents are less than 5 microamperes, the level of hypalgesia, so the plasma streamers induce a slight "tingling" sensation.

[0091] The microwave energy transmitted from the above-mentioned electrode 1 is transmitted from the electrode through the ionized air flow and combined with the underlying tissue that heats the tissue.

[0092] The temperature rise varies according to the microwave power provided by the power supply 1e, the microwave frequency, the moisture content of the tissue, and the residence time of the device on the skin spot provided.

[0093] Small changes in the distance between the electrode 1 and the skin 100 do not have a great impact on the microwave energy transfer based on the ionized gas flow. Thus, non-contact microwave treatment of the skin can be performed. Since there are no precise position specification requirements, the skin treatment process is extremely simple.

[0094] It is known that tissue heating has an anti-inflammatory effect and is helpful for acne treatment. Stable heating of a small local area can improve blood circulation and muscle tone.

[0095] In other embodiments, by locally closing or opening the valve, the compressed gas flow rate can be periodically adjusted. The low flow rate level is generally 0.1 - 3 m / s, and the high flow rate level is 5 - 10 m / s. The cycle frequency is 0.001 - 10 HZ. Thus, the undesired surface heating of the skin caused by the convective heat flow rate of the ionized air flow can be minimized, or the gas in the gas supply source 3 can be reduced.

[0096] In other embodiments, the auxiliary gas supply source 4 injects through the nozzle 4n with an ionized gas flow, and the gas is injected in a pulsed form by periodically opening and closing the valve 4v. The flow rate of the auxiliary gas is 1 - 10 m / s, and the pulse duration is 0.5 - 5 sec. The injection of the auxiliary gas reduces the convective heating of the skin surface, but does not have a great impact on the microwave heating of the basic tissue. In a preferred embodiment, the auxiliary air flow is directed towards the skin within the footprint of the ionized air flow. The auxiliary gas that collides with the skin and flows along the skin generates a thermal wall between the ionized air flow and the skin.

[0097] In other embodiments, the skin and tissue treatment using the device of the present invention is combined with light irradiation. (Refer to Figure 3 ) The light irradiation direction is set to irradiate the skin within the footprint of the ionized gas flow. The light may be in the wavelength range of 430 - 1100 nm. The simultaneous exposure to microwave heating, discharge, and light may have a synergistic effect on the treatment of acne and skin diseases.

[0098] In order to safely and with high quality treat a complex three-dimensional patient body part (e.g., the face), after the user confirms the size file of the skin of the body part to be treated and identifies the skin area to be treated, residence times, microwave and gas parameters are assigned to all treatment areas.

[0099] As Figure 4 、 5 shown, the robotic platform 8 performs automatic position designation and movement of the cavity 2, the electrodes 1 and the light sources 5, 5' components in the identified area according to the assigned treatment parameters and according to the three-dimensional skin file.

[0100] By adding tilting (W1, W2) mechanisms, the ionized air flow contacts the skin almost perpendicularly, and the ionized air flow moves to the next target treatment site after starting at the position of the robotic platform at the site to be treated or outside the body part.

[0101] The protective band 5e' can be attached to the eyes or other sensitive body parts or skin areas during manual or automatic skin treatment. The protective band can be made of sponge to protect the skin from convective heating.

[0102] The protective band 5e' can include a conductive layer (metal mesh) for providing local protection against microwave energy; the protective band 5e' can be grounded and can be manufactured in a disposable and self-adhesive manner.

[0103] The present invention can not only be used for treating skin tissue, but also for curing chronic wounds, especially for the recovery of diabetic and venous obstructive skin ulcers. Such treatment can reduce the bacterial colonization of the injured site and can improve the blood circulation of the basal tissue.
