Description

skin stimulator

[0001] The present invention relates to a skin stimulation device.

[0002] In general, a skin stimulation device that performs thermal stimulation by supplying electrical energy inserts a needle into a target area of ​​the skin and applies a high-frequency current to the needle, so that the high-frequency current is transmitted to the target area of ​​the skin through the needle.

[0003] The high-frequency current delivered to the target area of ​​skin through the needle is converted into thermal energy that instantly increases the temperature of the target area, inducing coagulative necrosis through tissue damage. This coagulative necrosis can then be naturally repaired through the body's natural repair mechanisms.

[0004] However, conventional skin stimulation devices have a problem in that the efficiency of tissue damage in the target area of ​​the skin is reduced because they only supply heat energy by transmitting high-frequency current to the target area of ​​the skin.

[0005] The present invention has been devised to solve the above-described problems, and the purpose of the present invention is to provide a skin stimulation device that can improve the efficiency of tissue damage to a target area of ​​the skin by simultaneously inflicting tissue damage by hydrogen explosion and tissue damage by heat energy on the target area of ​​the skin.

[0006] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0007] A skin stimulation device according to one embodiment of the present invention comprises: one or more cannulas inserted into or discharged from a target area of ​​the skin; a hydrogen gas supply part supplying hydrogen gas into the interior of the cannula; a current supply part supplying high-frequency current to the cannula; and a processor controlling the current supply part and the hydrogen gas supply part, wherein the processor operates the hydrogen gas supply part and the current supply part when the cannula is inserted into the target area to induce tissue damage in the target area.

[0008] Additionally, the processor can operate the current supply part after operating the hydrogen gas supply part while the cannula is inserted into the target area.

[0009] In addition, when the hydrogen gas supply part is operated, the hydrogen gas is injected into the target area, and when the current supply part is operated, the hydrogen gas injected into the target area explodes by the application of the high-frequency current, inducing first tissue damage in the target area, and at the same time, the heat energy generated by the high-frequency current transmitted to the target area can induce second tissue damage in the target area.

[0010] In addition, a channel through which hydrogen gas supplied from the hydrogen gas supply part flows may be formed inside the cannula, and an exhaust port through which the hydrogen gas flowing through the channel is exhausted may be formed on the circumference of the cannula.

[0011] In addition, the cylinder may further include a plunger through which one or more of the cannulas are penetrated and which is provided to be movable in a first direction away from the skin or a second direction toward the skin; and a driving part that moves the plunger in the first direction or the second direction.

[0012] In addition, the cannula may further include a cannula check valve that is provided in the cannula to prevent backflow of the hydrogen gas in the cannula and backflow due to explosion of the hydrogen gas in the target area, and to allow the hydrogen gas supplied to the cannula to flow only from the cannula to the target area.

[0013] In addition, the cannula may include a first cannula spaced apart from one side of the plunger; and one or more second cannulas spaced apart from the other side of the plunger, wherein the first cannula may include a first discharge portion formed on a surface opposite to the second cannula, and the second cannula may include a second discharge portion formed on a surface opposite to the first cannula.

[0014] In addition, the plunger may further include a cylinder in which the plunger is built to be movable in the first direction or the second direction; and a slip material coupled to the outer circumference of the plunger.

[0015] Additionally, the cylinder may further include a stopper installed therein to limit the range of movement of the plunger.

[0016] Additionally, the cannula may further include a vortex part formed in a spiral shape along the inner surface thereof.

[0017] Other specific details of the present invention are included in the detailed description and drawings.

Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0028] Figure 1 is a schematic diagram showing a skin stimulation device according to one embodiment of the present invention.

[0029] As illustrated in FIG. 1, a skin stimulation device according to one embodiment of the present invention may include a cannula (10a, 10b), a hydrogen gas supply part (20), a current supply part (30), and a processor (40).

[0030] A cannula (10a, 10b) can be inserted into a target area of ​​the skin (1). A channel (11) through which hydrogen gas supplied from a hydrogen gas supply part (20) to be described later flows can be formed inside the cannula (10a, 10b). In addition, an exhaust port (12a, 12b) through which hydrogen gas flowing through the channel (11) is exhausted can be formed on the circumference of the cannula (10a, 10b).

[0031] For example, the cannula (10a, 10b) may be composed of one or more, and may be composed of a single or multiple cannula.

[0032] As another example, the distal end of the cannula (10a, 10b) may have a sharp shape. Accordingly, the distal end of the cannula (10a, 10b) may be inserted into the target area of ​​the skin (1) to form an insertion hole in the target area of ​​the skin (1).

[0033] The hydrogen gas supply part (20) serves to supply hydrogen to the interior of the cannula (10a, 10b). Here, the interior of the cannula (10a, 10b) may be a channel (11) of the cannula (10a, 10b). This hydrogen gas supply part (20) can supply hydrogen to the interior of the cannula (10a, 10b) under the control of the processor (40).

[0034] The hydrogen gas supply part (20) may include a hydrogen gas tank (not shown), a hydrogen gas pipe (not shown), and a hydrogen gas check valve (not shown). Here, the hydrogen gas tank may store hydrogen gas. In addition, the hydrogen gas pipe may connect the hydrogen tank and the channel (11) of the cannula (10a, 10b). In addition, the hydrogen gas check valve may open and close the hydrogen gas pipe under the control of the processor (40), and may function as a one-way valve to allow the hydrogen gas stored in the hydrogen gas tank to flow only into the channel (11) of the cannula (10a, 10b). Therefore, when the hydrogen gas check valve opens the hydrogen gas pipe, the hydrogen gas stored in the hydrogen gas tank may be supplied to the channel (11) of the cannula (10a, 10b) through the hydrogen pipe. Additionally, when the hydrogen gas check valve closes the hydrogen gas pipe, the hydrogen gas stored in the hydrogen gas tank may not be supplied to the channel (11) of the cannula (10a, 10b) through the hydrogen pipe or the supply may be stopped.

[0035] The current supply part (30) can supply high-frequency current to the cannulas (10a, 10b). This current supply part (30) can receive power from the power supply part. Here, the power supply part can be a battery.

[0036] The processor (40) controls the current supply part (30) and the hydrogen gas supply part (20). This processor (40) can induce multiple tissue damages in the target area of ​​the skin (1) by operating the hydrogen gas supply part (20) and the current supply part (30) while the cannula (10a, 10b) is inserted into the target area of ​​the skin (1).

[0037] Specifically, the processor (40) can operate the hydrogen gas supply part (20) while the cannula (10a, 10b) is inserted into the target area, and then operate the current supply part (30). In other words, the processor (40) can sequentially operate the hydrogen gas supply part (20) and the current supply part (30) while the cannula (10a, 10b) is inserted into the target area. As a result, when the hydrogen gas supply part (20) is operated, hydrogen gas can be injected into the target area of ​​the skin (1). Thereafter, when the current supply part (30) is operated, the hydrogen gas injected into the target area of ​​the skin (1) explodes by the application of high-frequency current, inducing first tissue damage in the target area of ​​the skin (1) and at the same time, the heat energy generated by the high-frequency current transmitted to the target area of ​​the skin (1) can induce second tissue damage in the target area. As a result, since the first tissue damage and the second manipulation damage are simultaneously induced in the target area of ​​the skin (1), the tissue damage efficiency of the target area of ​​the skin (1) can be improved. Here, the first tissue damage in the target area of ​​the skin (1) can be caused by the physical impact resulting from the explosion of the hydrogen gas. In addition, the second tissue damage in the target area of ​​the skin (1) can be caused by a temperature increase in the target area of ​​the skin (1) due to the heat energy generated by the high-frequency current.

[0038] Meanwhile, a skin stimulation device according to one embodiment of the present invention may further include a cylinder (50), a plunger (60), and a driving part (70).

[0039] The cylinder (50) can serve as the basic body of the present invention. A handpiece can be used in place of the cylinder (50). For example, the cylinder (50) can be positioned facing the target area of ​​the skin (1). In another example, the cylinder (50) can be pressed against the target area of ​​the skin (1).

[0040] The plunger (60) may be provided with one or more cannulas (10a, 10b) penetrating therethrough and movable in a first direction away from the skin (1) or a second direction toward the skin (1) in the cylinder (50).

[0041] The driving part (70) can serve to move the plunger (60) in the first direction or the second direction. As an example, an actuator can be used as the driving part (70).

[0042] Additionally, the skin stimulation device according to one embodiment of the present invention may further include a cannula check valve (not shown).

[0043] A cannula check valve is provided in the cannula (10a, 10b) to prevent backflow of hydrogen gas in the cannula (10a, 10b) and backflow due to explosion of hydrogen gas at the target area of ​​the skin, and to allow hydrogen gas supplied to the cannula (10a, 10b) to flow only from the cannula (10a, 10b) to the target area of ​​the skin.

[0044] For example, a cannula check valve may be placed at the outlet (12a, 12b) of the cannula (10a, 10b).

[0045] Hereinafter, the operation process of a skin stimulation device according to one embodiment of the present invention will be described. Here, the operation process can be performed by a processor (40) or a practitioner.

[0046] Figures 2 to 4 are schematic diagrams showing the operation process of a skin stimulation device according to one embodiment of the present invention.

[0047] First, the cylinder (50) is pressed against the target area of ​​the skin (1) with the distal end of the cannula (10a, 10b) positioned facing the skin (1). (See Fig. 2)

[0048] Next, the driving part (70) moves the plunger (60) in a second direction toward the skin (1). As a result, the cannula (10a, 10b) is inserted into the target area of ​​the skin (1), thereby forming an insertion hole in the target area of ​​the skin (1). (See Fig. 3)

[0049] Next, the hydrogen gas supply part (20) and the current supply part (30) are sequentially operated. As a result, when the hydrogen gas supply part (20) is operated, hydrogen gas can be injected into the target area of ​​the skin (1). Thereafter, when the current supply part (30) is operated, the hydrogen gas injected into the target area of ​​the skin (1) explodes by the application of high-frequency current, thereby inducing first tissue damage in the target area of ​​the skin (1), and at the same time, the thermal energy generated by the high-frequency current transmitted to the target area of ​​the skin (1) can induce second tissue damage in the target area. As a result, since the first tissue damage and the second manipulation damage are simultaneously induced in the target area of ​​the skin (1), the tissue damage efficiency in the target area of ​​the skin (1) can be improved. (See Fig. 4)

[0050] For example, the cannula may include one or more first cannulas and one or more second cannulas.

[0051] One or more first cannulas (10a) may be spaced apart on one side of the plunger (60).

[0052] One or more second cannulas (10b) may be spaced apart on the other side of the plunger (60).

[0053] Here, the first cannula (10a) may include a first discharge portion (12a) formed on one surface facing the second cannula (10b), and the second cannula (12b) may include a second discharge portion (12b) formed on one surface facing the first cannula (10a). Accordingly, when one or more first cannulas (10a) and one or more second cannulas (10b) are inserted into a target area of ​​the skin (1), a relatively large amount of hydrogen gas may be concentrated in the target area of ​​the skin (1) between the first discharge portion (12a) of the first cannula (10a) and the second discharge portion (12b) of the second cannula (10b) that are adjacent to each other. Thereafter, when the current supply part (30) is operated, relatively large tissue damage may occur in the target area of ​​the skin (1) between the first discharge portion (12a) of the adjacent first cannula (10a) and the second discharge portion (12b) of the second cannula (10b). Through this, relatively large tissue damage may be caused in the area of ​​the target area of ​​the skin (1) where relatively large tissue damage is required.

[0054] Figures 5 to 7 are schematic diagrams showing various embodiments of a skin stimulation device according to one embodiment of the present invention.

[0055] As illustrated in FIG. 5, a skin stimulation device according to one embodiment of the present invention may further include a slip material (80).

[0056] A slip material (80) may be coupled to the outer circumference of the plunger (60). This slip material (80) may serve to seal the space between the cylinder (50) and the plunger (60). In addition, the slip material (80) may slip along the cylinder (50) when the plunger (60) moves in the first or second direction, and may also serve to reduce friction between the plunger (60) and the cylinder (50).

[0057] As illustrated in FIG. 6, the skin stimulation device according to one embodiment of the present invention may further include a stopper (90).

[0058] A stopper (90) is provided in the cylinder (50) to limit the movement range of the plunger (60). Such stoppers (90) may be configured in plurality, and one of the plurality of stoppers (90) is installed at the upper portion of the cylinder (50), and one of the plurality of stoppers (90) is installed at the lower portion of the cylinder (50), and can limit the movement range of the plunger (60).

[0059] Meanwhile, when a plurality of cannulas (10a, 10b) are inserted into a target area of ​​the skin (1), the surface of the skin (1) may become biased due to the pressure exerted by the plurality of cannulas (10a, 10b) on the surface of the skin (1). Among the plurality of cannulas (10a, 10b), the cannulas (10a, 10b) positioned at the center of the plunger (60) are inserted into the skin (1) in a more sagging state than the cannulas (10a, 10b) positioned at the edge of the plunger (60). To compensate for this, it is preferable that the lengths at which the plurality of cannulas (10a, 10b) protrude from the plunger (60) be different from each other. To this end, among the plurality of cannulas (10a, 10b), the cannulas (10a, 10b) positioned at the edge of the plunger (60) may protrude from the plunger (60) by a smaller length than the cannulas (10a, 10b) positioned at the center of the plunger (60). Therefore, when the plurality of cannulas (10a, 10b) are inserted into the target area of ​​the skin (1), the state in which the surface of the skin (1) is biased can be alleviated due to the pressure applied by the plurality of cannulas (10a, 10b) to the surface of the skin (1). (See Fig. 7)

[0060] FIG. 8 is a cross-sectional view showing an example of a cannula of a skin stimulation device according to one embodiment of the present invention.

[0061] As illustrated in FIG. 8, a skin stimulation device according to one embodiment of the present invention may further include a vortex part (13).

[0062] The vortex part (13) can be formed in a spiral shape along the inner surface of the cannula (10a, 10b). This vortex part (13) can form a vortex in the hydrogen gas flowing along the cannula (10a, 10b). In this way, when the hydrogen gas with the vortex formed is discharged through the discharge portion (12a, 12b) of the cannula (10a, 10b), it can spread to a wider area of ​​the target area of ​​the skin (1).

[0063] According to the present invention, a skin stimulation device according to one embodiment of the present invention has the effect of improving the efficiency of tissue damage in a target area of ​​the skin (1) by simultaneously applying tissue damage by hydrogen explosion and tissue damage by heat energy to the target area of ​​the skin (1).

[0064] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
