Description

High-frequency skin beauty device with simultaneous insertion of thermal energy to multi-depth point in dermis layer}

The present invention relates to a high-frequency skin beauty device, and more particularly, by simultaneously outputting heat energy to multiple locations in the depth direction in the dermal layer, the penetration range of thermal energy is wide so that the treatment effect is excellent, and the simultaneous injection of multi-depth heat energy in the dermis layer. It relates to the device.

Human skin consists of an epidermal layer, a dermal layer, and a subcutaneous fat layer. The epidermal layer prevents the invasion of bacteria and prevents the body from getting out of the body, and the dermal layer contains fibrous proteins and substrates such as collagen and elastin, and plays a role in providing an influence to the epidermal layer. In addition, the subcutaneous fat layer is located in the lower part of the dermis layer and functions to absorb pressure or shock from the outside and maintain body temperature.

As the skin ages, the elasticity gradually decreases and wrinkles are formed. This is largely because the amount of collagen, elastin, and matrix inside the dermal layer decreases, and the amount of moisture decreases.

Various types of cosmetic procedures are known to prevent skin aging. Among them, a method of applying nutrients to the skin and massaging it, a method of injecting a cosmetic liquid into the skin using a syringe, and a method of applying high frequency to the epidermal layer so that high frequency is applied to the dermis layer. There are ways to make it indirectly delivered.

However, the above various cosmetic procedures have a disadvantage that the duration of the effect is short and must be managed periodically, and accordingly, the management cost is increased.

In order to solve this problem, a method of regenerating and activating collagen or elastin by inserting a thin needle into the dermal layer to stimulate the tissue forming the dermal layer and simultaneously outputting heat energy in the dermal layer has been proposed.

For example, in Korean Patent Publication No. 10-1122526 (a skin beauty treatment device that is convenient to replace the needle assembly), the needle assembly and needle assembly are reciprocated, so that the tip of the needle can reach the dermal layer. A skin beauty treatment device is disclosed having a servo motor, a shaft, and a high-frequency energy generating means. The high frequency output from the high frequency energy generating means is emitted through the tip of the needle and solidifies the tissue around the tip.

However, in the case of the skin beauty treatment device of the prior patent, since the lengths of the needles fixed to the needle assembly are all the same, it has a disadvantage that heat energy is transferred only to the same depth inside the dermal layer. For example, if the needle assembly is advanced by only 1 mm into the dermal layer, heat energy acts only on the 1 mm deep portion of the dermal layer, and sufficient heat energy does not reach the 0.5 mm deep or 1.5 mm deep areas. Accordingly, as shown in FIG. 7B, a heat energy non-reaching portion Y is generated, to which the heat energy has not reached.

In order to input heat energy to the non-reach area (Y), after removing the needle from the dermal layer, adjusting the stroke distance of the shaft, and then inserting the needle again, this itself is cumbersome and can cause burns of the skin tissue. It causes a number of side effects, such as causing.

FIG. 1 is a perspective view showing an external appearance of a high-frequency skin beauty device 10 simultaneously inputting multi-depth thermal energy in a dermal layer according to an embodiment of the present invention, and FIG. 2 is a partial exploded perspective view of the skin beauty device. In addition, FIG. 3 is an exploded view showing the body part 20 and the skin irritation part 30 in the skin care device.

As shown, the high-frequency skin beauty apparatus 10 according to the present embodiment includes a body portion 20 and a skin irritation portion 30. The skin irritation part 30 contains a needle assembly (40 in FIGS. 4 and 9) described later, serves to stimulate the skin, and is detachable from the body part 20. The skin irritation part 30 is used for replacement.

For the detachable coupling of the skin irritation portion 30 to the body portion 20, a detachable passage (21d) and a locking protrusion (21e) at the end of the body portion, and a fitting protrusion (31c) at the skin irritation portion 30 Is formed. For the coupling of the skin irritation portion 30 to the body portion 20, the skin irritation portion 30 is in close contact with the end of the body portion 20, but after passing the fitting protrusion 31c through the detachable passage 21d, the watch It is achieved by rotating it in the direction or counterclockwise.

The drive unit 26 serves to reciprocate the shaft 23 within a predetermined stroke range. As long as it can play such a role, the type of the driving unit 26 can be variously changed. For example, a motor, a ball screw, a pneumatic actuator, an electromagnet device, etc. can be applied.

The high frequency generator 28 has a built-in high frequency oscillation circuit, converts the power supplied through the power line 22 into high frequency current pulses, and transmits it to the high frequency terminal unit 25. The high frequency terminal unit 25 transfers the high frequency energy received from the high frequency generator 28 to the needle assembly 40.

The control unit 27 serves to control the driving unit 26 and the high frequency generator 28. The control unit 27 is also connected to a switch (not shown) arranged on the outer surface of the case 21. The user can manipulate the switch to generate a control signal.

The shaft 23 is a round bar-shaped member having a predetermined diameter and is connected to the driving part 26 and a part thereof extends toward the skin irritation part 30. The extended end of the shaft 23 is connected to the needle assembly 40 to move the needle assembly 40 up and down.

In the following description, the downward movement of the needle assembly 40 refers to a movement in a direction away from the main body part 20, and the upward movement refers to a movement toward the body part 20 side.

The high frequency terminal unit 25 is symmetrically disposed around the shaft 23, and is electrically connected to the fixed substrate (32 in Fig. 4) in a state in which the skin irritation unit 30 is coupled to the body unit 20. .

In addition, a contact surface 31a is formed at the end of the cap 31 and a plurality of needle holes 31b are formed in the contact surface 31a. The contact surface 31a is a surface in contact with the patient's skin during the procedure. When the needle assembly 40 is lowered while pressing the skin with the contact surface 31a, the needle of the needle assembly passes downward through the needle hole 31b to stimulate the dermal layer of the skin.

4 and 5 are cross-sectional views illustrating an example of the skin irritation unit 30 shown in FIG. 3. In addition, FIG. 6 is a view separately showing the needle shown in FIG. 4.

As shown, the skin irritation part 30 includes a cap 31 opened to the top, a fixed substrate 32 fixed horizontally to the inlet of the cap 31, and a needle installed under the fixed substrate 32 The assembly 40 has a support for supporting the needle assembly.

The fixed substrate 32 is horizontally fixed to the inside of the cap 31 and maintains an electrical connection with the high frequency terminal 25 as described above. In addition, the shaft 23 is passed downward through the center hole 32a formed in the central portion, so that the lower end of the shaft 23 can be connected to the needle assembly 40.

A horizontal support plate 33 is installed under the fixed substrate 32. The horizontal support plate 33 is a blocking plate that restrains the needle assembly 40 supported by the spring 36 from rising more than that.

The needle assembly 40 includes an elevating substrate 41, a connection terminal 43, a driven plate 34, and a needle 45. The elevating board 41 is a circuit board on which a circuit for transmitting a high-frequency signal to each needle 45 is formed. The driven plate 34 is a plate-like member fixed to the rim of the elevating substrate 41 and has a shaft fixing portion 34a at the center thereof. The shaft fixing part 34a is a part that is coupled to the lower end of the shaft 23.

In addition, the connection terminal 43 is a telescopic terminal that can be stretched in the longitudinal direction, and the lower end is fixed to the elevating substrate 41, and the fixed substrate 32 passes upward through the driven plate 34 and the horizontal support plate 33. Stay connected to Since the connection terminal 43 is expandable and contractible, the connection terminal 43 is always electrically connected to the fixed substrate 32 even if the elevating substrate 41 rises or descends as shown in FIG. 4 as shown in FIG. 4.

The needle 45 can be raised and lowered with its upper end connected to the elevating substrate 41, extending vertically, and partially accommodated in the needle hole 31b. The needle 45 is accommodated in the cap 31 when the elevating substrate 41 is raised. However, when the elevating substrate 41 descends, as shown in FIG. 5, it is exposed to the lower portion of the cap 31 and pierces the dermal layer (B) of the skin.

The needle 45 is composed of a main needle 45a and a plurality of fixed needles 45b. The main needles 45a are fixed to the elevating substrate 41 and extend vertically, and a plurality of the main needles 45a are spaced apart at regular intervals. The spacing of the main needles 45a may vary as needed.

The fixed needle 45b is a linear needle member fixed to the main needle 45a. Each of the fixed needles 45b enters the dermal layer B together with the main needles 45a and serves to stimulate the dermal layer, and may have an angle between 5 degrees and 15 degrees with respect to the main needles 45a. In addition, the upper end of each fixing needle (45b) may be fixed to the main needle (45a) by a welding method.

In particular, the heights of the lower ends of the fixing needles 45b are different from each other, and the lower ends of the fixing needles 45b at the bottom are positioned higher than the lower ends of the main needles 45a. In the needle 45, the lower end of the main needle 45a and the lower end of each fixed needle 45b are spaced apart in the horizontal and vertical directions.

The vertical distance between the lower end of the main needle 45a and the lower end of each of the fixed needles 45b (H in FIG. 6) varies depending on the number of applied fixed needles 45b, and is 1/n of the thickness of the dermal layer (B). (n is the number of fixed needles) or less.

In addition, portions excluding the lower end of the main needle 45a and the lower end of all the fixing needles 45b are coated with an insulating layer 45d. The lower end of the main needle and the lower end of the fixed needle are not coated and serve as an energy discharging tip 45e.

The insulating layer is a blocking layer formed of parylene, Teflon, or ceramic, and blocks dissipation of high-frequency energy. The high-frequency energy is output only through the energy discharging tip 45e on which the insulating layer 45d is not coated. For example, when a high frequency is applied to the needle 45 shown in FIG. 4, as shown in FIG. 7C, a plurality of thermal energy reaching regions Z are distributed in the thickness direction of the dermal layer B. Simultaneous input of heat energy to the multi-depth area in the dermal layer (B) is made.

On the other hand, the support part is to elastically support the needle assembly 40, the support frame 35 to wrap and protect the rim of the elevating substrate 41, a plurality of springs 36 for elastically supporting the support frame 35 , Has a spring support (31f) to support the spring (36). The spring 36 upwardly supports the elevating substrate 41 while being supported by the spring support 31f. By the action of the spring 36, the driven plate 34 is in elastic contact with the bottom surface of the horizontal support plate 33.

The operation of the high-frequency skin care device 10 having the above configuration is performed as follows. First, while the operator grips the body part 20, the contact surface 31a of the cap 31 is in close contact with the patient's skin. When the above-described switch is operated in this state, the drive unit 26 lowers the shaft 23 in the direction F in FIG. 4.

When the shaft 23 descends, the needle assembly 40 connected to the shaft 23 descends together, and the needle 45 passes through the epidermal layer (A) as shown in FIG. 5 and passes through the dermal layer (B). Poke. As soon as the needle is inserted into the dermal layer (B), the high-frequency generating unit 28 operates, and thermal energy is output through the energy discharging tip 45e of the needle.

The output heat energy coagulates the tissues of the multi-depth area inside the dermal layer (B), and regenerates and activates collagen. With one shot, the heat energy is transferred to the multi-depth tissue in the dermal layer at once.

When the shaft 23 and the needle assembly 40 rise after the above-described process is completed, the operator moves the cap 31 to make close contact with the next treatment site, and repeats the above-described operation.

7A, 7B, and 7C are views for reference to explain how the needle shown in FIG. 6 simultaneously outputs heat energy to a multi-depth portion of the dermis layer and the action of a conventional needle. Reference numeral A is an epidermal layer, B is a dermal layer, and C is a subcutaneous fat layer.

7A is a view of outputting high frequency energy through vertical non-insulating needles 101 that are not coated with an insulating layer. The heat energy reaching region Z is formed thinly only around the non-insulating needle 101.

7B is an example of outputting a high frequency through an insulating needle 103 in which a portion except the lower end portion is insulating coated. As shown, the thermal energy reaching region Z is formed near the lower end of the insulating needle 103. It can be seen that the heat energy non-reach area Y is located above and below the heat energy reach region Z.

7C is a view showing a state in which high frequency is simultaneously injected through a needle 45 used in the skin care device of this embodiment. As shown, a plurality of heat energy reaching regions Z are formed around the energy discharging tips 45e of the main needle 45a and the plurality of fixed needles 45b. The heat energy reaching region (Z) is close to the subcutaneous fat layer (C) and the epidermal layer (A), and coagulates the internal structure of the dermal layer (B).

8A and 8B are diagrams for explaining the structure and operation of a needle 46 of another type that can replace the needle shown in FIG. 6.

The needle 46 shown in FIG. 8A is composed of a main needle 46a parallel to each other and a plurality of fixed needles 46b. The fixing needle 46b is connected to the main needle 46a through a connecting member 46f and is parallel around the main needles. The connection member 46f, like the main needle 46a and the fixing needle 46b, is made of stainless steel, and electrically connects the fixing needle 46b to the main needle 46a. The fixing of the main needle 46a and the fixing needle 46b to the connection member 46f can be implemented by a welding method.

In addition, all portions except the lower end of the main needle 46a and each fixed needle 46b are coated with an insulating layer 46d, and the lower end of the main needle 46a and the fixed needle 46b is an energy discharging tip 46e. Plays the role of.

In addition, the heights between the main needle 46a and the lower end of each of the fixed needles 46b are different. Therefore, as shown in FIG. 8B, when the needle 46 is inserted into the dermal layer (B) and then high-frequency energy is applied, a heat energy reaching region (Z) is simultaneously formed in the multi-depth area inside the dermal layer.

In some cases, the upper portion of the connecting member 46f may be applied as a separate support rod rather than a needle. That is, a configuration connecting the main needle 46a and the fixed needle 46b to the lower end of the support rod may be applied.

9 to 11 are cross-sectional views showing another type of skin irritation unit 30 that can be applied to the skin care device 10 according to an embodiment of the present invention, and FIG. 12 is a view of the cap shown in FIG. It is a view showing the arrangement pattern of the needle hole 31b.

The needle assembly 40 shown in FIG. 9 includes an upper elevating substrate 47a, an upper needle 49a, a lower elevating substrate 47b, a lower needle 49b, and a spring 48.

The upper elevating substrate 47a is a circuit board connected to the fixed substrate 32 through a connection terminal 43, and has an upper needle 49a at the lower portion thereof. A plurality of the upper needles 49a form a predetermined interval, pass downward through the lower elevating substrate 47b, and extend vertically downward. The upper elevating substrate 47a is combined with the driven plate 34 and moves together with the driven plate.

The high frequency transmitted through the fixed substrate 32 and the connection terminal 43 is transmitted to the upper needle 49a through a circuit inside the upper lifting substrate 47a. The high frequency transmitted to the upper needle 49a is ejected to the periphery through the energy discharging tip 49f at the lower end of the upper needle 49a. A portion of the upper needle except for the energy discharging tip 49f is coated with an insulating layer 49c.

The lower elevating substrate 47b is located under the upper elevating substrate 47a and supported by a support frame 35 and a spring 36. The lower elevation type substrate 47b is connected to the fixed substrate 32 through another connection terminal 44. The high frequency applied to the fixed substrate 32 is transmitted to the lower elevation type substrate 47b through the connection terminal 44.

The lower elevating substrate 47b is a circuit board on which a circuit is formed like the upper elevating substrate 47a and has a plurality of lower needles 49b. The lower needle 49b is a vertical needle having an energy discharging tip 49f formed at its lower end, and portions excluding the energy discharging tip 49f are coated with an insulating layer 49c.

The length of the lower needle 49b is longer than the length of the upper needle 49a. In particular, as shown in FIG. 11, in a state in which the upper and lower elevating substrates 47a and 47b are lowered as much as possible, the lower end of the lower needle 49b is relatively lower than the lower end of the upper needle 49a. Located. For reference, the lower ends of the upper and lower needles 49a and 49b in the state in which the upper and lower elevation substrates 47a and 47b are lowered as far as possible are located inside the dermal layer (B).

The upper needle 49a is located between the lower needles 49b. That is, one upper needle 49a is inserted between the two lower needles 49b in parallel. The interval between the lower needle 49b and the upper needle 49a is half of the pitch of the lower needle 49b.

Since the upper and lower needles 49a and 49b have the above arrangement pattern, the needle hole 31b formed on the contact surface 31a of the cap 31 has the shape shown in FIG. 12.

In addition, the spring 48 is interposed between the lower elevating substrate 47b and the upper elevating substrate 47a, and serves to space the upper and lower elevating substrates 47a and 47b as far as possible in a state in which no external force is applied. Do it.

In addition, the spring 48 acts so that the gap between the lower elevating substrate 47b and the upper elevating substrate 47a is no longer narrowed in a compressed state. As shown in FIG. 11, the spring 48 is compressed as much as possible in a state in which the upper and lower elevating substrates 47a and 47b reach the bottom dead center.

A method of using the high frequency skin care device 10 having the above configuration is as follows. First, as shown in FIG. 9, in a state in which the upper needle 49a and the lower needle 49b are raised, the contact surface 31a of the cap 31 is in close contact with the patient's skin.

When the close contact is completed, a switch (not shown) disposed on the main body 20 is operated to lower the shaft 23 in the direction of the arrow F. When the shaft 23 descends, the upper elevating substrate 47a compresses the spring 48 and is as close as possible to the lower elevating substrate 47b (see Fig. 10). The energy discharging tip and the lower portion of the upper needle 49a The gap between the energy discharging tips of the needle 49b is minimized.

When the shaft 23 is further lowered in this state, the upper and lower lifting substrates 47a and 47b are lowered to the bottom dead center, and the energy discharging tips 49f of the upper and lower needles 49a and 49b are as shown in FIG. It is located in the dermal layer (B).

As soon as the energy discharging tips 49f of the upper and lower needles 49a and 49b reach the dermal layer (B), the high frequency terminal unit 25 operates, and thermal energy is output from the energy discharging tips 49f to coagulate surrounding tissues. . After the above process is completed, if the needle assembly 40 is raised by the driving unit 26, the above process is repeated.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical idea of the present invention.
