Description

TECHNICAL FIELD [0001] The present invention relates to a microneedle high frequency system for treating an acne disease,

The present invention relates to a microneedle high frequency system for treating acne diseases, and more particularly to a microneedle high frequency system for use in various types of acne such as adult acne, wheat acne, recurring acne, purulent acne and juvenile acne. And to a method of operation for treating acne disorders.

The skin that covers our entire body consists of three layers: the epidermal layer, the dermal layer, and the subcutaneous fat layer.

The epidermis is the most surface layer of the skin. Depending on its position and function, the epidermis is composed of several layers such as stratum corneum, transparent layer, granular layer, superficial layer and basal layer, and functions as protection, defense and secretion.

In addition, the dermis layer is located below the epidermis layer and is positioned adjacent to the basal layer to form the majority of the skin. The dermis layer is composed of water, proteins, saccharides, mucopolysaccharides, minerals, inorganic salts, And a reticular layer containing elastin and a matrix (a reservoir of water), elastic fibers that give skin elasticity, collagen, which is the collagen fibers associated with the wrinkles of the skin.

Finally, the subcutaneous fat layer is located between the dermis, muscles and bones, and contains a large amount of fat. It constitutes the lowest layer of the skin and spreads evenly throughout the body, absorbing external pressure and shock due to elasticity maintenance and buffering action It not only prevents damage to the inside of the body but also prevents the loss of body heat and maintains body temperature.

On the other hand, chronic inflammatory diseases of the hair follicle gland are various skin changes such as cotton papules, papules, blisters, nodules, and false cysts, resulting in a concave scar or enlarged scars. Acne is a disease that occurs in the face, neck, chest, where sebaceous glands are gathered, and inflammation occurs in sebaceous glands attached to hair follicles. Acne usually appears in puberty, but acne occurring in puberty continues until after age 25, or in the late 20s, is called adult acne. Adult acne is more likely to leave scar rather than adolescence and early treatment is important.

Although the cause of acne is not known precisely, genetic factors and environmental factors are known to be associated with the colonization of acne bacteria and sebaceous glands, and it is known that acne is caused by excessive oil, It is known that irritation, stress, and excessive sweating can make or exacerbate acne.

It is divided into the medicine to treat acne, the medicine to eat, and the surgical treatment.

Most of these drugs have a direct sterilization effect against acne bacteria, and the medicine to eat has antibiotics and retinoids that sterilize acne bacteria and reduce inflammation. Retinoids are known to cause fetal anomalies during pregnancy.

On the other hand, there are surgical treatments for symptomatic areas such as surgical treatment, acne extrusion treatment, and peeling. If acne is squeezed excessively, scarring is often left after treatment, so acne scar treatment is necessary.

The high frequency current causes very little ion motion because of the very short amplitude of vibration when the body tissue is energized, and does not cause electrochemical reaction or electrolysis phenomenon. 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 dermatological disorders, high frequency is widely used in various fields such as acne treatment, wrinkle lifting, scar treatment by acne, injection of filler.

In the conventional high-frequency treatment system for skin treatment, there is a problem that the physician causes the patient to suffer from high-frequency radiation error in performing the high-frequency treatment to the patient.

Korean Patent Laid-Open No. 10-2015-0007938 " Skin treatment apparatus " is disclosed.

The handpiece is provided with a holder part and a signal for supplying a signal to the holder part. The handpiece is attached to the holder part, . The treatment unit includes a surgical needle inserted into the skin; A support plate connected to the surgical needle and restricting movement of the user to the skin; And an insertion plate connected to the support plate and mounted to the holder portion. To prevent risks such as the transmission of germs, the treatment unit used is discarded and replaced with a new one.
