Description

TECHNICAL FIELD [0001] The present invention relates to a high frequency therapeutic apparatus and a therapeutic method using the same. BACKGROUND OF THE INVENTION [0002]

The present invention relates to a high frequency treatment apparatus and a treatment method using the same. More particularly, the present invention relates to a high frequency treatment apparatus and a treatment method using the same, in which a high frequency current is conducted in the body by using a needle inserted into the skin as an electrode.

When a high frequency current is energized in the body, deep heat is generated in the human body tissue. The deep heat is a living body heat generated by rotating motion, warping, collision, and the like, because molecules constituting the human tissue are vibrated by vibrating with each other due to high-frequency electric energy.

Recently, as a method for treating skin such as acne treatment, pore reduction, wrinkle removal, and scar removal, a high frequency treatment apparatus using a micro needle as an electrode has been developed and used.

Such a high-frequency treatment apparatus can reach the dermal layer through a part or all of the skin layer of the micro needle. Accordingly, the high frequency treatment apparatus using the micro needle has an advantage that the high frequency current is smoothly conducted even in the dermal layer, thereby improving the treatment efficiency.

However, a high frequency treatment apparatus using a micro needle is used in a manner that a plurality of micro needles are simultaneously inserted into the skin. Even if the diameter of the microneedles is fine, if a large number of microneedles are simultaneously inserted into the skin, the microneedles may not be smoothly inserted according to the surface resistance of the skin.

In addition, when a large number of micro needles are inserted into the skin at the same time, the resulting pain is multiplied, causing pain to the patient receiving treatment. Thus, the pain caused during the treatment with the microneedle may lead to a problem that the patient is reluctant to be treated, despite the excellent therapeutic effect of the RF treatment device.

Referring to FIG. 6, a plurality of micro needles may be used as the plurality of needles 300. That is, each of the needles 300 may have a diameter of about 20 mu m. Each of the needles 300 is used as an electrode 311 for allowing a high-frequency current to pass through the skin in an interval of about 0.3 mm from the tip. In each needle 300, an insulating portion 312 is formed in which a portion of about 200 mu m from the electrode is coated with an insulating material such as silicon. The insulating portion 312 prevents a high-frequency current from flowing to a portion other than the portion requiring treatment.

That is, when the skin area requiring treatment is flattened by suction through the suction holes 800, the plurality of needles 300 can be inserted into the skin with a small force.

Further, when the suction hole 800 is disposed so as to surround the side surface of the suction hole 800, the suction hole 800 may further include a recess portion 810 that forms a suction surface of the suctioned skin. The recess portion 810 can be arranged to form a flat surface so that the skin can be directly seated and the plurality of needles 300 can be inserted into the skin without great resistance.

The suction holes 800 may be arranged in parallel to the plurality of through holes 310. In addition, the handpiece 200 may have a predetermined height at an upper edge thereof and may be disposed in a direction perpendicular to the through hole 310. However, the suction holes 800 may be variously deformed so as to evenly absorb the skin area into which the respective needles 300 can be inserted.

The tensile force of the skin or the pressure of the skin inhaled by the suction hole 800 can be measured through the sensing unit 500 connected to the suction hole 800. The sensing unit 500 senses a change in the tension of the skin as the suction hole 800 sucks the skin so that the plurality of needles 300 can be inserted into the skin when the tension of the skin is greater than a predetermined value And can transmit the signal to the control unit 700. [ Alternatively, the sensing unit 500 senses a predetermined value for attracting the skin to the suction hole 800, and can transmit a signal to the controller 700 so that the plurality of needles 300 can be inserted into the skin.
