Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin treatment apparatus using ultrasound and high frequency,

More particularly, the present invention relates to a skin treatment apparatus, and more particularly, to a skin treatment apparatus that uses a micro needle with ultrasonic vibration to reduce pain upon insertion of a foreign body, applies a high frequency current to the needle and performs ultrasonic vibration, The present invention relates to a skin treatment apparatus using ultrasonic waves and high frequencies and a control method thereof, which can provide various thermal effects to the skin tissue by concentrating the ultrasound and high frequency waves.

A radio frequency (RF) as commonly known is generally referred to as an alternating current of 1 MHz or more.

Since the high-frequency current has a very short vibration width when the human body is energized, ion motion hardly occurs and there is no electrochemical reaction or electrolysis phenomenon.

When a high frequency current is energized in the human body, heat is generated in the tissue, which is called deep heat. This is because, when high-frequency electric energy is applied, the molecules constituting the tissue vibrate each other as the direction of the current changes, thereby generating biothermal heat due to rotational motion, warping, and collision.

Unlike other forms of current, high-frequency currents that do not stimulate sensory and motor nerves can heat certain areas of the body tissue without causing discomfort or muscle contractions in the body. The high frequency energy converted into the biomedical thermal energy increases the temperature of the tissue, thereby enhancing the function of the cell and increasing the blood flow.

In general, the functional recovery temperature of a known tissue is 40 to 60 ° C. When the local temperature of the tissue goes up to 40 ℃ or higher, direct arterial and capillary dilation occurs and blood flow increases to improve the body defense mechanism and improve blood circulation and metabolism.

Increase in capillary blood flow due to deep heat generation is 4-5 times higher than at rest.

In addition, the supply of oxygen, nutrients, antibodies, leukocytes and the like is increased, and vasodilation increases the hydrostatic pressure of the capillaries, thereby promoting the lymphatic circulation.

Such a high-frequency deep heat regenerating device is known to be effective for lifting, wrinkling, whitening, hair loss treatment, and obesity management (abdomen).

Therefore, a number of skin treatment devices using such high frequency electric energy have been developed in recent years.

However, the conventional skin treatment apparatus using high frequency has the following problems.

First, there is a problem that the length and diameter of the needle invading the skin are large, causing pain and slowing the recovery.

1 is a circuit block diagram of a skin treatment apparatus using ultrasonic waves and high frequencies according to an embodiment of the present invention.

As shown in the drawings, the present invention provides a skin treatment apparatus using ultrasound and high frequency,

A control unit 110, a high frequency generating unit 120, a vibration ultrasonic wave generating unit 130, a heating ultrasonic wave generating unit 140, a nozzle driving unit 150, a temperature detecting unit 160, 180).

The controller 110 controls the overall operation of the skin treatment device.

The high frequency generator 120 generates a high frequency and applies it to the microneedles 182b of the handpiece 180. The high frequency generator 120 includes a high frequency oscillating unit for outputting a high frequency signal in response to a pulse oscillation signal output from the controller 110 And a high frequency output unit 122 receiving the output of the high frequency oscillating unit 121 and receiving a control signal of the controller 110 to perform high frequency output of a high voltage and low current type.

The high-frequency generating unit 120 transmits high-frequency energy to the micro needle 182b inserted into the skin to generate a deep heat.

Here, the output frequency of the high frequency output unit 122 is 1 MHz, and the waveform can be configured to have various waveforms such as a square wave, a triangle wave, a sine wave, and a step wave.

The oscillating ultrasonic wave generator 130 is a circuit for ultrasonic vibrating the microneedles 182b of the handpiece 180 and outputs an oscillation signal having a predetermined pulse width by the control output of the controller 110 An inverter unit 132 for generating and outputting an AC signal in accordance with an oscillation signal output from the first oscillation circuit unit 131 and a second oscillation circuit unit 131 for outputting a signal current output from the inverter unit 132, And an amplification output unit 133 for amplifying the amplified signal and applying the amplified signal to the oscillator means for oscillating the microneedle 182b.

The vibration ultrasonic generator 130 vibrates the vibrator means on which the microneedle 182 to be described later is mounted to greatly mitigate the pain when the microneedle 182b is inserted into or withdrawn from the skin.

Here, the operating frequency of the ultrasonic wave generator 130 is preferably 30 KHz.

The heating ultrasonic wave generator 140 is a circuit for ultrasonic vibrating the microneedles 182b of the handpiece 180 and outputs an oscillation signal having a predetermined pulse width by the control output of the controller 110 An inverter unit 142 for generating and outputting an AC signal in accordance with the oscillation signal output from the second oscillation circuit unit 141 and a second oscillation circuit unit 141 for outputting the signal current outputted from the inverter unit 142 And an amplification output unit 143 for amplifying the amplified signal and applying the amplified signal to the oscillator means for oscillating the microneedle 182b.

The heat generating ultrasonic wave generator 140 vibrates the microneedles 182b inserted into the skin to transmit ultrasonic energy to the skin to generate heat.

Here, the operating frequency of the ultrasonic wave of the ultrasonic wave generator 140 is preferably 1 MHz.

 Meanwhile, the handpiece 180 is configured such that the needle portion 182 is mounted inside the tip portion 181 as shown in FIG.

The needle portion 182 is configured such that a plurality of microneedles 182b are mounted on the vibrator means 182a and the needle portion 182 protrudes out of the tip portion 181 through the conveying means 183 Out or inward to be inserted.

For example, FIG. 2A shows a state in which the needle portion 182 protrudes out of the distal end portion 181, and FIG. 2B shows a state in which the needle portion 182 is inserted inward.

The conveying unit 183 for operating the needle unit 182 in two steps may be implemented using a solenoid, for example.

The needle portion 182 does not necessarily need to be structured such that the microneedle 182b is mounted on the vibrator means 182a and constitutes a separate member to which the microneedle 182b is fixed, It is also possible to arrange the oscillator means so as to be in contact with each other. It is possible to change design as much as necessary.

A high frequency current outputted to the high frequency generator 120 is applied to the microneedle 182b of the needle unit 182 and the vibrator means 182a is connected to the ultrasonic wave generator 130 for vibration and the ultrasonic wave generator (140) is applied.

3, an infrared ray irradiating unit 184 and an infrared ray receiving unit 185 are further formed at the distal end portion 181 of the handpiece 180. [

The infrared ray irradiating unit 184 emits infrared rays to the skin S1 of the human body and the infrared ray receiver 185 receives the infrared ray reflected from the skin S1 and detects the temperature of the skin S1 .

The nozzle driving unit 150 drives the feeding unit 183 for moving the nozzle unit 182 of the handpiece 180 forward and backward. The nozzle driving unit 150 drives the feeding unit 183 according to the output of the controller 110, Respectively.

The temperature detector 160 measures the temperature of the skin detected through the infrared ray irradiator 184 and the infrared ray receiver 185 mounted on the handpiece 180 and inputs the measured temperature to the controller 110.

The reason for detecting the skin temperature through the temperature detector 160 is to monitor the skin temperature in real time so that the high frequency energy can be irradiated when the skin temperature reaches the appropriate temperature range.

This is based on the principle that the high-frequency temperature is transmitted to the higher side and is intended to further improve the treatment efficiency.

The operation unit 170 has a touch screen function and includes a switch for displaying a current output state, a skin surface temperature, a set value, etc., setting an output level, an output type, and selecting operation start and end.

FIG. 5 is a control procedure showing a control method of a skin treatment apparatus using ultrasonic waves and high frequencies according to the present invention.

As shown in the figure, the method of controlling a skin treatment apparatus using ultrasonic waves and high frequencies includes:

A step S10 of oscillating the microneedle 182b by transmitting ultrasonic vibration output to the microneedle 182b of the handpiece 180 and a step S11 of inserting the microneedle 182b into the affected part (S12) for stopping the vibration ultrasonic wave output; applying a high frequency current to the microneedle (182b) of the handpiece (180) for a predetermined period of time; (S14) for stopping the high-frequency output and the ultrasonic wave output for a predetermined period of time (S14); determining whether the operation set time for the high-frequency and ultrasonic driving has elapsed or the output stop command has been input (S15); and if the operation set time for high frequency and ultrasonic driving has elapsed or the output stop command has been inputted in the determining step (S15), the high frequency and ultrasonic driving (S17) of vibrating the microneedle 182b by transmitting ultrasonic vibration output to the microneedle 182b of the handpiece 180, and a step (S17) of vibrating the microneedle 182b, (S18) of stopping the vibration ultrasonic wave output, and stopping the ultrasonic vibration output (S19).

Here, in step S10, it is preferable that the ultrasonic vibration output is radiated for 100 msec.

In the step S12, it is preferable to maintain the stop time of the ultrasonic vibration output for 200 msec.

In the step S13, the high frequency output time is preferably output for 50 msec, but is not limited thereto.

In the step S14, the high frequency output stop time is preferably maintained for 50 msec, but is not limited thereto.

In the above steps (S13) and (S14), the generation time of the ultrasonic wave for heating may or may not be the same as the high frequency output.

The overall operation of the skin treatment apparatus using the ultrasound and high frequency waves of the present invention will be described with reference to FIG.

First, when power is supplied through a power supply unit (not shown), the user sets the output mode (high frequency and ultrasonic output time and intensity, etc.) through the operation unit 170.

After the tip 182 of the handpiece 180 is brought into contact with the skin S1 of the affected part as shown in Fig. 4 (a), a drive start switch is inputted through the operation part 170. Fig.

When a key signal of a drive start switch of the operation unit 170 is inputted, the controller 110 outputs an ultrasonic wave generation signal to the ultrasonic wave generator 130 for vibration.

The vibration ultrasonic generator 130 applies an ultrasonic output of 30 KHz to the vibrator means 182a of the nozzle unit 182 of the handpiece 180 through the amplification output unit 133 and the vibrator means 182a, The micro needle 182b is also vibrated in conjunction with the vibration of the micro needle 182b (step S10)

When the microneedle 182b vibrates, the controller 110 outputs a driving command to the nozzle driver 150 to the driving unit 183.

Accordingly, the nozzle driving unit 150 drives the conveying unit 183 to cause the nozzle unit 182 inside the tip end portion 181 to protrude outward as shown in FIG. 4 (b) (Step S11). Then,

At this time, the patient is reduced in pain through the process of vibrating and inserting the micro needle 182b.

The micro needle 182b is inserted into the skin layer S1 as shown in FIG. 4C to cause a deliberate wound T on the dermal layer S2.

When the insertion of the microneedle 182b is completed, the controller 110 stops outputting the ultrasonic wave to the ultrasonic wave generator 130 to stop the vibration of the microneedle 182b (step S12)

The control unit 110 outputs a high-frequency generating signal to the high-frequency generating unit 120 and an ultrasonic generating signal to the ultrasonic wave generating unit 140.

Therefore, the high frequency generating unit 120 applies a high frequency output of 1 MHz to the micronozzle 182b of the handpiece 180 through the high frequency output unit 122 to generate instantaneous high frequency waves through the micronozzle 182b The ultrasonic wave generating unit 140 applies an ultrasonic output of 1 MHz to the vibrator means 182a of the nozzle unit 182 of the handpiece 180 through the amplification output unit 143, The microneedles 182b are vibrated in conjunction with the vibration of the microneedles 182a (Step S13)

4 (d) through the micronozzle 182b, high energy is delivered to the dermis layer S2 to induce skin regeneration effect through partial (about 9%) necrosis And the vibration reduces the pain and bleeding effect.

When the high frequency and the ultrasonic output are maintained for a predetermined time (e.g., 50 msec), the controller 110 interrupts the output of the high frequency generator 120 and the ultrasonic generator 140 for a predetermined time (e.g., 50 msec) Thereby cutting off the high frequency and ultrasonic output through the needle 182b (step S14)

The control unit 110 determines whether an operation stop time has elapsed due to the high frequency and ultrasonic driving set through the operation unit 170 or an output stop command has been inputted. If the operation stop time has elapsed or the input stop instruction The operation of steps S13 and S13 is repeatedly performed (step S15).

However, if it is determined in operation S15 that the operation set time has elapsed due to high frequency and ultrasonic driving, or if an output stop command has been input, the high frequency and ultrasonic driving is stopped (operation S16)

The control unit 110 outputs the ultrasonic wave generation signal to the ultrasonic wave generation unit 130.

Accordingly, the ultrasonic generator 130 for vibration transmits the ultrasonic output of 30 KHz to the microneedle 182b through the amplification output unit 133 (step S17)

When the microneedle 182b vibrates, the controller 110 outputs a driving command to the nozzle driving unit 150 to the driving unit 183.

The nozzle driving unit 150 drives the conveying unit 183 to draw the microneedle 182b to the inside of the tip end portion 181 again as shown in Figure 4 (e) (step S118)

When the immobilizing of the microneedle 182b is completed, the control unit 110 stops the output to the ultrasonic wave generator 130 for vibration and stops the vibration of the microneedle 182b (step S19)

The skin on which the microneedles 182b are removed is subjected to a natural regeneration process.
