Description

Handpiece for skin treatment {Skin Treatment Handpiece}

The present invention relates to a handpiece for skin treatment, and more particularly, to a handpiece for skin treatment using energy to enable non-invasive skin treatment.

The skin covering the entire body consists of three layers: the epidermis, dermis, and subcutaneous fat.

Among them, the epidermal layer is the most superficial layer of the skin, and it is composed of several layers such as the stratum corneum, transparent layer, granular layer, stratum corneum, and basal layer depending on the location and function, and is responsible for protection, defense, and secretion.

In addition, the dermis layer is located below the epidermis layer and is located adjacent to the basal layer to make up most of the skin. Water, proteins, carbohydrates, mucopolysaccharides, minerals, inorganic salts, etc. are in a jelly state, so that capillaries and It is composed of the papillary layer, where the lymphatic vessels that transport lymph are located, and the reticular layer containing collagen, a collagen fiber that is related to wrinkles in the skin, elastin, an elastic fiber that gives elasticity to the skin, and a matrix (reservoir of water).

Lastly, the subcutaneous fat layer is located between the dermis, muscles, and bones, contains a large amount of fat, and constitutes the lowest layer of the skin. It not only prevents damage to the inside of the body, but also prevents the loss of body heat and maintains body temperature.

As a skin treatment method for preventing skin aging as described above, in addition to the traditional method of massaging the skin using a cosmetic material containing nutrients, a method of injecting a cosmetic solution into the skin using a syringe or the like is widely used. Not only does it cost a lot of money, but it also causes many side effects depending on people's constitution, causing adverse effects on the skin.

In addition, a surgical method that indirectly transmits radio waves from the epidermal layer to the dermis layer is also used. There was a big problem in the inconvenience and cost burden of having to undergo the procedure.

A high-frequency skin treatment method that directly delivers high-frequency current to the dermis layer of the skin through a needle to activate cell tissues, maintaining elastic skin and minimizing skin aging, is in the spotlight.

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

Meanwhile, a treatment method using high-power pulsed light (IPL: Intense Pulsed Light) has been developed.

HIFU (Focused Ultrasound Therapy) is a procedure that burns tissues by using high heat of 65 to 100°C that is generated at the focus when high-intensity focused ultrasound energy is collected in one place in the deep part of the skin.

When ultrasound, which is about 100,000 times stronger than the intensity of ultrasound used for diagnosis, is focused on one place, heat is generated at the focal point.

At this time, since the ultrasound itself is harmless to the human body and heat is generated only at the focus of the ultrasound, the HIFU (High Intensity Focused Ultrasound Therapy) does not use a knife or needle and does not require general anesthesia to treat lesions in the body. there is.

Such HIFU (high-intensity focused ultrasound therapy) is being used in the field of skin care recently. Depending on the purpose of use (e.g., skin care, obesity care, etc.), a specific frequency and treatment depth for generating HIFU energy must be fixed. Therefore, HIFU energy suitable for the purpose of the treatment or the treatment site is delivered to the skin, but the cartridge for the handpiece is provided, which is differentiated according to the depth of the ultrasonic wave that penetrates the skin.

Conventional devices for skin treatment, including HIFU equipment, require a variety of cartridges for handpieces due to differences in the patient's skin condition, depth of treatment area, thickness of skin tissue, etc. Since the procedure is performed while replacing the cartridge, the procedure is cumbersome, and it is difficult to manage a large number of cartridges.

The dial 62 is made in the shape of a disk, and the level of the treatment depth of energy is displayed on the outer peripheral surface. This energy treatment depth level can be displayed numerically, and by matching the reference point, the position of the ultrasound generator can be adjusted so that the treatment can be performed with a depth of the corresponding level. This will be described later.

A front end 22 in contact with the skin is formed at the front end of the main body 2, and a cable connector 24 through which the power cable 24 is coupled is coupled to the rear end.

A through hole 220 is formed in the front end 22 to allow energy to pass therethrough.

The dial 62 indicates the level of the treatment depth of energy. That is, after forming zones by forming a plurality of protrusions on the outer circumferential surface of the dial 62 at regular intervals, the level is displayed in numbers for each zone.

Preferably, it is divided into levels of 1.5 mm, 3.0 mm, and 4.5 mm depending on the treatment depth.

It should be noted that this is merely an example and is not necessarily limited to these numerical values.

A pointer 63 is formed on one surface of the dial 62 to selectively contact the sensor 92 of the PCB 9 .

A plurality of sensors 92 are arranged in an arc shape in the PCB 9, and each sensor 92 corresponds to a level one-to-one. Therefore, when the pointer 63 of the dial 62 corresponds to the sensor 92, it means that it is set at the corresponding level.

The operation of the present invention configured in this way will be described as follows.

Rotate the dial 62 to set the desired level gauge.

When the dial 62 is rotated, the pointer 63 corresponds to any one of the plurality of sensors 92 and is set to a specified level accordingly.

In addition, as the dial 62 is rotated, the cam 64 is rotated, and the support pin of the movable member 66 reaches a certain point of the concave portion 644 or the protrusion 642 of the cam 64 . Shaft 69 will move towards the front end 22 or towards the dial 62 .

Therefore, as shown in Fig. 5 (a), when the shaft 69 is moved to a distance from the front end 22 by rotating the dial 62, the energy generating unit 4 is a through hole of the front end 22. The distance to 220 is changed to a long distance. It is set at the 1.5mm level.

On the other hand, as shown in Fig. 5 (b), when the shaft 69 is moved toward the front end 22 by rotating the dial 62 in reverse, the energy generating unit 4 is the front end 22 The distance with the through hole 220 of the becomes close. It is set at the 3mm level.

On the other hand, as shown in Fig. 5 (c), when the shaft 69 is moved toward the front end 22 by further rotating the dial 62 in reverse, the energy generating unit 4 is the front end 22. The distance from the through hole 220 of the nearest. It is set at a level of 4.5mm.

By adjusting the distance between the energy generating unit 4 and the front end 22 in this way, it is possible to adjust the ultrasound treatment depth.

In the case of a triangular cross-sectional shape, the strength is somewhat high, which may be insufficient in some cases in relieving pressure.

In the case of a wavy cross-sectional shape, in addition to contraction and relaxation due to a curved shape, a change in volume can be facilitated to relieve a greater pressure due to deformation such as narrowing or swelling of the cross-sectional area. Accordingly, the stretchable member may be selected as needed.

In addition, the wrinkle portion may be one in which the concave portion and the convex portion alternately and repeatedly forms a gently curved surface, and one of the concave portion and the convex portion is formed to have a thinner thickness than the other. With a thin area, the contraction is fast and smooth.
