Lifting beauty device using high-intensity focused ultrasound}

The present invention relates to a lifting beauty device using high-intensity focused ultrasound. More specifically, it relates to a high-intensity focused ultrasound that irradiates high-intensity focused ultrasound (HIFU) to the SMAS (Superficial Musculo Aponeurotic System) layer, which is a fibrofascial layer that is part of the muscle layer, or the dermal layer. This is about a lifting beauty device using .

In general, as many people begin to take interest in beauty, interest in skin care is also increasing day by day.

The desire for healthy skin is not limited to the beauty field, but is also influencing the growth of medical products to protect skin health from ultraviolet rays and various types of pollution, which are becoming stronger due to the destruction of the ozone layer.

Face lifting is a wrinkle removal surgery that aims to improve the aging phenomenon of the facial area by removing sagging skin on the face and neck and pulling the subcutaneous tissue to remove wrinkles.

Recently, during face lifting, an endoscope method has been used to minimize scars by making as few incisions as possible.

However, since this method is an invasive surgical operation, it is accompanied by bleeding, secondary infection, pain, and long-term recovery period, causing many difficulties for the recipients.

Among invasive methods, advanced medical technologies such as lasers are being developed and commercialized, but difficulties accompanying invasive surgery still exist.

Therefore, in recent years, there has been a growing need for technology that can beautify the skin in a non-invasive way.

Generally, the SMAS layer, which is part of the muscle layer, is the muscle area that is pulled when performing face lifting surgery. When high-intensity focused ultrasound is used to act only on the SMAS layer without touching the epidermis, the heat caused by the ultrasound is delivered to the deep dermal layer. , Clinical results are being reported overseas that this can regenerate collagen and achieve the effect of removing wrinkles and improving skin elasticity.

In line with this trend, there is a non-invasive beauty device that uses high intensity focused ultrasound (HIFU) that has recently been in the spotlight.

For skin beauty treatment, there is an ultrasonic beauty device that irradiates high-intensity focused ultrasound to shallow skin tissue to perform skin lifting or skin tightening procedures. The above-mentioned ultrasonic beauty device uses high-intensity focused ultrasound (HIFU) on the subcutaneous fat layer and dermal layer. ) is irradiated to stimulate subcutaneous tissue by burning, melting, or decomposing it, thereby eliminating wrinkles and improving skin elasticity.

Therefore, the lifting beauty device using high-intensity focused ultrasound according to an embodiment of the present invention consists of two irradiation depths of 4.5 mm and 3.0 mm, and the SMAS (Superficial Musculo Aponeurotic System) layer, which is the fibrofascial layer, and the dermal layer. High-intensity focused ultrasound can be selectively irradiated to each area, or high-intensity focused ultrasound can be irradiated to both the SMAS (Superficial Musculo Aponeurotic System) layer and the dermal layer.

In addition, the cartridge unit 200 according to an embodiment of the present invention with reference to FIGS. 9 to 11 includes a cartridge housing that includes a rotational force transmission means 220, a head transfer means 230, and a head module 240. (210) The inside is filled with a liquid medium (water (H₂O), etc.), and the high-intensity focused ultrasound irradiated from the oscillation head 300 is propagated to the skin surface through the filled liquid medium.

At this time, an opening 211 is formed at the upper end of the cartridge housing 210, which is in contact with the skin surface, and has an area corresponding to the area where the high-intensity focused ultrasound waves radiated from the oscillation head 300 are irradiated. , high-intensity focused ultrasound waves are propagated to the skin surface through the opening 211.

For example, during the manufacturing process of an ultrasonic device, it is very difficult to fill the medium 100% completely, and although a small amount of gaseous medium may flow in, if the introduced gaseous medium is located in the focused ultrasound propagation path, the interference of the gaseous medium causes ultrasonic waves. Attenuation of energy occurs.

In addition, when the device is repeatedly used, heat is generated, and air dissolved in water comes out in a gaseous state, generating air bubbles (gaseous medium), and the air bubbles cause attenuation of ultrasonic energy.

Therefore, the cartridge unit 200 according to an embodiment of the present invention has a partition wall 213 extending inward to a certain length along the circumference of the opening 211 of the cartridge housing 210, and the cartridge unit 200 as described above. It prevents the gaseous (air) medium unintentionally released inside the housing 210 from flowing into the moving area (corresponding to the area of the opening 211) of the ultrasonic oscillation head 300.

As an example of the operation, when the opening 211 of the cartridge housing 210 according to an embodiment of the present invention is directed downward, the gaseous medium generated inside the cartridge housing 210 has a relative density than the liquid medium. is low, the gaseous medium moves upward, and when the cartridge housing 210 is rotated so that the opening 211 of the cartridge housing 210 faces upward, the gas generated inside the cartridge housing 210 The gaseous medium is blocked by the partition wall 213 and does not flow into the moving area (corresponding to the area of the opening 211) of the ultrasonic oscillation head 300, so the moving area of the ultrasonic oscillation head 300 (opening 211) corresponds to the area), only the liquid medium exists.

Therefore, even when high-intensity focused ultrasound waves are irradiated from the ultrasonic oscillation head 300, attenuation of ultrasonic energy by the gaseous medium does not occur.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached patent claims.
