Hereinafter, an embodiment of a beauty medical device 100 according to the present invention will be described in detail with reference to the attached drawings. In a description with reference to the attached drawings, like or corresponding elements will be referred to as like reference numerals and a repetitive description thereof will be omitted.
According to one embodiment of the present invention, there is provided the beauty medical device 100 including a handpiece body 110 including an ultrasonic emission surface 122 at one end, an ultrasonic generation unit 120 installed in the handpiece body 110 and configured to generate an ultrasonic wave and emit the ultrasonic wave toward skin through the ultrasonic emission surface 122, and a radio frequency generation unit 130 disposed at the one end of the handpiece body 110 on a periphery of the ultrasonic emission surface 122 and configured to generate a high frequency, that is, a radio frequency (RF).
According to the present invention, the beauty medical device 100 includes both the ultrasonic generation unit 120 and the radio frequency generation unit 130 so as to simultaneously or alternately perform ultrasonic treatment and radio frequency treatment.
Accordingly, when the ultrasonic treatment and the radio frequency treatment are performed using the beauty medical device 100 according to the present invention, an overall treatment time may be reduced and a skin lifting effect or an adipolysis effect may be improved. Also, since both the ultrasonic treatment and the radio frequency treatment may be performed using one handpiece, a practitioner may conveniently perform treatment.
Hereinafter, respective components of the beauty medical device 100 according to the embodiment will be described with reference to
As shown in
Also, since it is necessary to replace the cartridge portion when a certain number of ultrasonic waves are generated, the cartridge portion may be detachably coupled to the body portion.
As shown in
As shown in
The above-described focused ultrasonic wave may be emitted toward thin skin tissue to be used for face lifting or skin tightening treatment and may be emitted toward a subcutaneous layer to be used for obesity treatment which burns or melts and splits fatty tissue.
Accordingly, since a focal depth of the focused ultrasonic wave is set to be different according to a purpose of treatment, the cartridge portion including the ultrasonic generation unit set with a different focal depth may be replaced. As shown in
The radio frequency may be classified according to definition thereof and may have a frequency range of 30 kHz to 300 MHz. The radio frequency may be applied to the skin so as to provide effects of skin rejuvenation, skin elasticity improvement, stimulation of blood and lymph circulation, and the like.
The radio frequency generation unit 130 may adjust the frequency of the radio frequency so as to adjust a depth at which transmitted radio frequency energy is focused. In detail, the radio frequency generation unit 130 may decrease the frequency of the radio frequency so as to transmit energy deeper.
The radio frequency generation unit 130 may set a depth at which energy is focused to be different by adjusting the frequency according to a purpose of treatment for face lifting, skin tightening treatment, or adipolysis treatment.
Accordingly, energy may be focused on a corium layer, a fascial plane, or a superficial musculo-aponeurotic system (SMAS) layer which is located at about 1.5 mm to 4.5 mm from a surface of the skin and a thermal lesion or thermal coagulation area may be formed so as to perform face lifting or skin tightening treatment. In order to form an energy-focused depth for face lifting or skin tightening treatment, in detail, a radio frequency at 1 MHz to 2 MHz may be applied.
Also, energy may be focused on a subcutaneous layer located at about 8 mm to 13 mm from the surface of the skin so as to perform adipolysis treatment of burning or melting fatty tissue. To form an energy-focused depth for the adipolysis treatment, in detail, a radio frequency at 300 kHz and 500 kHz may be applied.
When the radio frequency generation unit 130 adjusts the frequency to overlap the energy-focused depth with a focal depth of an ultrasonic wave generated by the ultrasonic generation unit 120, an effect of treatment may be increased and a treatment time may be reduced.
The radio frequency generation unit 130 may generate a radio frequency with multi-pulses a plurality of times for a short time. When the radio frequency is applied a plurality of times, as the number of application increases, resistance at an application area decreases. Accordingly, an energy loss may be reduced and energy may be focused so as to increase an effect of treatment.
Also, the cooling unit 140 may cool the radio frequency generation unit 130 heated by a radio frequency for a standby time before the radio frequency generation unit 130 generates the radio frequency with multi-pulses and generates a next radio frequency. Accordingly, skin damage caused by heat generated by the radio frequency generation unit 130 may be prevented.
Meanwhile, a skin cooling portion which will be described below may cool the skin for an intermediate standby time of the multi-pulses and prevent damage to the skin.
The radio frequency generation unit 130 may include a plurality of such radio frequency electrodes 132 arranged on the periphery of the ultrasonic emission surface 122. The number, arrangement, and the like of the radio frequency electrodes 132 may be formed to be different according to a shape of the ultrasonic emission surface 122. In more detail, the arrangement of the radio frequency electrodes 132 will be described below.
As shown in
The contact sensor 160 may sense contact between the one end of the handpiece body 110 and the skin through a pressure, current, and the like, may sense whether contact with the skin is occurring, and may transmit a data signal thereof to the control unit 150 which will be described below. In the embodiment, for example, a capacitance sensor may be used as the contact sensor 160.
As shown in
Also, the control unit 150 may adjust a frequency generated by the radio frequency generation unit 130 according to a focal length set in the ultrasonic generation unit when the cartridge portion is replaced. In detail, the control unit 150 may adjust the frequency of a radio frequency to overlap an ultrasonic focal depth with a radio frequency energy focused depth according to replacement of the cartridge portion so as to improve an effect of treatment and to reduce a treatment time.
Meanwhile, a printed circuit board 170 electrically connected to the radio frequency generation unit 130 and the contact sensor 160 and configured to control the same may be installed at the one end of the handpiece body 110.
Generally, the printed circuit board 170 includes an insulation substrate, and a plurality of holes may be formed to allow electrical components to be coupled and a circuit may be printed on a surface of a substrate.
As shown in
As shown in
Unlike the above, as shown in
As shown in
However, the ultrasonic generation unit 120 and the radio frequency generation unit 130 may be operated at the same time to perform adequate treatment on a person to be treated according to a treatment environment, a treatment method, and the like.
As shown in
At least one of the ultrasonic generation unit 120 and the radio frequency generation unit 130 according to the present invention may generate heat while operating. The radio frequency electrode 132 of the radio frequency generation unit 130 of the embodiment may generate heat of about 60 degrees.
Not only may the heat generated by at least one of the ultrasonic generation unit 120 and the radio frequency generation unit 130 damage a component coupled to the handpiece body 110 but also the one end of the handpiece body 110 which is overheated during treatment may come into contact with the skin and damage the skin. To remedy the above problem, the cooling unit 140 may be installed on the handpiece body 110.
Also, when a temperature inside the handpiece body 110 exceeds a preset temperature, the control unit 150 may control the operation of the cooling unit 140.
In detail, when the temperature inside the handpiece body 110 increases due to heat caused by the operation of at least one of the ultrasonic generation unit 120 and the radio frequency generation unit 130, to prevent a problem caused by the overheating, the control unit 150 may operate the cooling unit 140 to lower the temperature inside the handpiece body 110 when the temperature inside the handpiece body 110 exceeds the preset temperature.
The skin cooling portion (not shown) may be formed on the cartridge portion and cool a treated region.
The skin cooling portion may spray a cooling gas for cooling the skin over the skin so as to reduce damage to the skin caused by the treatment. Also, the skin may be cooled by absorbing heat of the skin using a Peltier module or cooling water.
