In addition, the terms described below are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a schematic view of a skin treatment device according to an embodiment of the present invention. Referring to FIG. 1, a skin treatment apparatus 1 according to an embodiment of the present invention includes a treatment unit 10, a holder unit 20, and a handpiece unit 30. Such a skin treatment device 1 energizes a signal to the skin, that is, a high frequency current to remove inflammation or improve the beauty.

The treatment section 10 is inserted into the skin 100 of the patient to stimulate the skin 100 (see FIG. 3), and the holder section 20 is coupled with the treatment section 10 to send a signal to the treatment section 10 . At this time, the treatment section 10 can be detachably attached to the holder section 20. [ The handpiece portion 30 is engaged with the holder portion 20 and supplies a signal to the holder portion 20. The handpiece unit 30 has a shape that can be grasped by a user, and a signal supply unit (not shown) for connecting the holder unit 20 and supplying a signal may be incorporated. The skin treatment apparatus 1 according to an embodiment of the present invention includes a ground unit (not shown) for making a circuit with a human body in contact with a patient, a switch unit (not shown) for applying power to the handpiece unit 30 Not shown) may be further provided.

That is, the skin tissue of the human body is composed of the epidermis and the subcutaneous tissue of the lower part. The epidermal layer having the stratum corneum acts as a biological barrier to the environment, and the melanin cells that determine the skin color exist in the basal layer. In addition, the subcutaneous tissue of the lower part maintains the structure of the skin by acting as a supporter of extracellular protein collagen. Collagen is synthesized by fibroblasts, and three polypeptides are spirally structured proteins. In the event of a wound, the body operates a complex relief function, in which fibroblasts are present under the skin and are activated to transiently enter the extra cellular matrix (ECM) . As the fibroblasts slowly move around the matrix while pulling the fibers to recombine, the matrix becomes increasingly stiff and, due to the growth factors involved in the matrix initially in a soft state, the fibroblasts express the contractile protein by the growth factor, At some point, fibroblasts stop moving and turn into strong contractile cells such as popeye, which settles within the matrix and attracts the wound edges, resulting in scarring or uneven surface of the skin. At this time, the collagen fiber structure is heated by a predetermined energy source, the physical properties of the protein matrix are changed at a specific temperature, the molecular binding of the matrix is broken, the skin condition is evened, and the collagen layer is activated So that the elasticity of the skin can be restored.

Using the above-described principle, the remodeling of the tissue is realized by irradiating high-frequency energy to the subcutaneous tissue and raising the temperature of the subcutaneous tissue. Especially, the high frequency current causes very little ion motion and does not cause electrochemical reaction or electrolysis because the vibration width is very short when the body tissue is energized. When high-frequency electrical energy is applied to tissue, molecules of the tissue vibrate and rub against each other whenever the direction of current changes, generating biothermal heat. In addition, these high frequencies do not stimulate the sensory nerve and motor nerve unlike other current types, do not cause discomfort or contraction in the human body, can generate heat energy, and this heat energy also enhances the function of the cells An additional effect of increasing blood flow can be induced. In the treatment of dermatologic disorders, high frequency can be widely used in various fields such as acne treatment, wrinkle lifting, scar treatment by acne, injection of filler.

Referring to FIGS. 2 to 4, a surgical needle 11 according to an embodiment of the present invention is formed by cutting an end portion of the skin 100 to form a multi-facet.

That is, when the end of the treatment needle 11 has a conical shape, when the end of the treatment needle 11 penetrates the skin 100, the skin 100 is not cut. This makes it possible for the skin 100 to push out the insulating layer 15 when the operation needle 11 is completely inserted into the skin 100 so that the durability of the insulating layer 15 coated on the treatment needle 11 have. However, in the operation needle 11 according to the embodiment of the present invention, the processed surface 111 is formed and the skin 100 is incised when inserted into the skin 100. This makes it possible to improve the durability of the insulating layer 15 because the skin 100 can not push the insulating layer 15 even if the operation needle 11 is completely inserted into the skin 100.

The treatment needle 11 can form six processing surfaces 111 to cut the skin 100. The processing surface 111 is formed on the outer side of the treatment needle 11 and has a length in the axial direction of the treatment needle 11. At this time, the cross-sectional area of the treatment needle 11 decreases toward the end. When the processing surface 111 is formed at the end of the treatment needle 11, the surface of the skin 100 is opened while the end of the treatment needle 11 penetrates the surface of the skin 100 (see FIG. 3).

The treatment needle 11 may be made of a stainless steel material among conductive metallic materials. At this time, the processing needle 111 can be formed with a plurality of processing surfaces 111 by etching.
