Background

For modern people who are increasingly interested in skin beauty, various methods of treating the skin are being tried in various forms, for example, treating acne, shrinking pores, removing wrinkles and removing scars.

Among them, the most typical is a method of massaging with cosmetics or medicines containing skin nutrients. However, when cosmetics or drugs are delivered through the skin, the drugs hardly permeate the stratum corneum of the skin, and thus there is a problem of low absorption rate.

Recently, a skin surgery method using an injection needle, a microneedle, or the like to directly inject a drug into the inside of the skin has been introduced. Among them, korean patent laid-open No. 10-0955310 discloses a structure in which a disk shaped disc having a plurality of needles is brought into contact with the skin and rotated to pierce the skin, and then a medicine is applied to improve the absorption effect of the medicine.

However, in the above-described conventional skin surgery method, there is a problem that the disk-shaped disk rotates only in one direction, and in a state where the disk is in contact with the skin, in order to change the rotation direction to the left and right directions, the disk needs to be separated from the skin, the rotation direction thereof needs to be changed to a desired rotation direction, and then the disk needs to be brought into contact with the skin again.

In contrast, the existing skin surgery methods have a problem of reducing the convenience and effectiveness of the surgery.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely preferred embodiments of the present invention and do not replace the technical idea of the present invention, and therefore, various equivalent technical solutions and modifications that can replace these may exist at the time of the present application, and the scope of the present invention is not limited to the embodiments described below.

Fig. 1 is an exploded perspective view of a skin surgery device according to an embodiment of the present invention, and fig. 2 is a view showing the structure of the skin surgery device of fig. 1.

Referring to fig. 1 and 2, the skin surgery device 10 of the present embodiment may include: a body unit 100; a needle unit 200 coupled to one side and the other side of the body unit 100; and a medicament container 300.

A first coupling portion 110 to which the needle unit 200 is inserted and coupled may be formed at one side of the body unit 100, and a second coupling portion (not shown) to which the medicine container 300 is inserted and coupled may be formed at the other side corresponding to the one side. Wherein the first coupling portion 110 and the second coupling portion may be connected and communicated with each other inside the body unit 100.

A driving part 120 is formed inside the body unit 100 to control operations of the needle unit 200, for example, operations of skin piercing, drug injection, electrical stimulation, optical stimulation, and the like of a user (i.e., an operator). A switch unit 130 including one or more switches for driving the driving unit 120 may be formed outside the body unit 100.

In this state, the user can perform a skin operation, i.e., a skin operation such as drug injection, electrical stimulation, and optical stimulation, by using the needle unit 200, which will be described later, while holding the body unit 100 with a hand.

Referring to fig. 2, a driving part 120 capable of controlling a skin operation by the needle unit 200 may be formed inside the body unit 100. Such a driving part 120 may include a pumping part 121, a first current output part 122, a second current output part 123, a vacuum control part 125, and a power control part 127.

The suction part 121 may change the internal pressure of the needle unit 200 according to the control of the vacuum control part 125. The suction part 121 may suck air inside the needle unit 200 to make the internal pressure of the needle unit 200 smaller than the external pressure or discharge air to the inside of the needle unit 200 to make the internal pressure of the needle unit 200 the same as the external pressure. Such a suction portion 121 may be constituted by a vacuum pump (not shown).

On the other hand, when the internal pressure of the needle unit 200 is reduced by the operation of the suction unit 121, the skin of the user contacting the needle unit 200 may be sucked into the needle unit 200. At the same time, a predetermined amount of the medicine is supplied to the medicine container 300 coupled to the second coupling portion of the body unit 100 by being discharged to the needle unit 200.

Also, according to the operation of the suction part 121, the internal pressure and the external pressure of the needle unit 200 are the same, and the skin adsorbed on the needle unit 200 is restored to an original state while the medicine is not discharged from the medicine container 300.

The vacuum control unit 125 may control at least one of the strength and time of the air suction and discharge of the suction unit 121 to adjust the skin absorption of the needle unit 200 and the medicine discharge amount of the medicine container 300.

The first current output part 122 may output a first current of a predetermined intensity, for example, a high frequency RF current, to the needle unit 200 according to the control of the power supply control part 127. The first current output in the first current output part 122 may be transmitted through the needle unit 200 to the inside of the skin of the user to perform the skin surgery.

The second current output part 123 may output a second current of a predetermined intensity, for example, a light emitting diode current, to the needle unit 200 according to the control of the power supply control part 127. The second current outputted from the second current output part 123 can be used to perform a skin operation by transmitting a predetermined amount of light to the skin of the user by emitting light from one or more light emitting devices 221 of the needle unit 200.

The power control unit 127 may control at least one of the output intensity and the output time of the first current and the second current. Under the control of the power supply control unit 127, the first current output unit 122 and the second current output unit 123 can simultaneously output the first current and the second current. The first current output unit 122 and the second current output unit 123 may sequentially output the first current and the second current.

Referring back to fig. 1, the needle unit 200 can be detachably coupled to the first coupling portion 110 of the body unit 100. The needle unit 200 may include a ball (ball) -shaped needle roller 210 that is rotated in a prescribed direction on the skin of a user and pierces the skin of the user, injects a medicine through the pierced hole, and applies an electrical stimulus to the skin.

Fig. 3 is an exploded perspective view of the needle unit of fig. 1, and fig. 4 is a sectional view cut along lines iv to iv' after the needle unit of fig. 3 is assembled.

Referring to the drawings, the needle unit 200 of the present embodiment may include a needle roller 210, a placing portion 220, a spring 230, a fixing portion 240, and a guide 250.

The needle roller 210 may be in a spherical state. The needle roller 210 is placed on a placement unit 220 described later, and can freely rotate in either direction, for example, 360 degrees, on the skin of a user.

The needle roller 210 may include a plurality of microneedles 211 and a plurality of guide protrusions 212 protrudingly formed at an outer circumferential surface thereof. When the needle unit 200 is in contact with the skin of a user, the plurality of microneedles 211 may pierce the skin of the user to form a structure of a prescribed depth. The plurality of guide protrusions 212 may prevent the plurality of microneedles 211 from being damaged by the inner side surface of the placement portion 220.

Fig. 5 is a view specifically showing the needle roller of fig. 3.

Referring to fig. 5, the needle roller 210 of the present embodiment may have a plurality of microneedles 211 and a plurality of guide protrusions 212 respectively formed along the outer circumferential surface thereof in a protruding manner. The microneedles 211 and the guide protrusions 212 may be formed integrally with the needle roller 210.

The needle roller 210 may pierce the skin of the user through the plurality of microneedles 211. Also, the needle roller 210 may apply electrical stimulation to the inside of the skin of the user through the plurality of microneedles 211, in other words, may apply high frequency current. To this end, the needle roller 210 of the present embodiment may be formed of a conductive material, for example, a metal material such as lead. Of course, the microneedles 211 and the guide projections 212 formed integrally with the needle roller 210 may be formed of a metal material.

The cross section of each of the plurality of microneedles 211 may have a conical structure in a triangular form. The plurality of microneedles 211 may be formed to protrude at a height d1 of 0.2 to 0.5mm, respectively.

When the needle roller 210 is rotated by being brought into contact with the skin of a user, the plurality of microneedles 211 may pierce the skin and form a hole of a prescribed depth, thereby absorbing the drug supplied in the body unit 100 into the skin through the hole and applying a first current supplied in the body unit 100 into the skin through the hole.

The plurality of guide protrusions 212 may be formed on the outer circumferential surface of the needle roller 210 in at least one of the lateral, longitudinal, and diagonal directions, or may be formed between the plurality of microneedles 211. The plurality of guide protrusions 212 may have a semicircular shape in section and may have a hemispherical structure. The plurality of guide protrusions 212 may have a height greater than that of the microneedles 211, and may be formed to protrude with a height d2 of 0.3 to 0.6mm, for example.

As described above, since the height d2 of the plurality of guide protrusions 212 is greater than the height d1 of the plurality of microneedles 211, the plurality of guide protrusions 212 preferentially contact the inner surface of the placement portion 220 compared to the plurality of microneedles 211, and thus, the plurality of microneedles 211 can be prevented from being damaged by the inner surface of the placement portion 220.

Also, the plurality of guide protrusions 212 may have a hemispherical structure, so that when the needle roller 210 rotates, friction between the needle roller 210 and the inner side of the placing part 220 may be reduced to smoothly rotate the needle roller 210.

Referring back to fig. 3 and 4, the seating portion 220 of the needle unit 200 may have a hemispherical shape with an upper end open and a lower side recessed. The needle roller 210 may be inserted and placed inside such a placing portion 220.

A portion corresponding to one half of the needle roller 210 may be placed on the placing portion 220. In this regard, the needle roller 210 protruding from the placement portion 220 may come into contact with the skin of the user.

Also, in the placing part 220, the diameter of the upper end opening part may be smaller than that of the needle roller 210. When the needle roller 210 is inserted, the upper end opening of the placement portion 220 is expanded to a fixed degree, and when the needle roller 210 is inserted into the placement portion 220 and placed, it is restored to the original position. In contrast, the placing portion 220 may be formed of a plastic material having a predetermined elasticity.

One or more light emitting devices 221 may be disposed at one end of the placement portion 220, for example, around an upper end opening portion into which the needle roller 210 is inserted. The light emitting device 221 may emit light by emitting light through the second current output from the driving part 120 of the body unit 100 described above, i.e., through the light emitting diode current. In this case, the light emitting device 221 may be a red light emitting diode, and the skin surgery of the user, for example, phototherapy, is performed by red light emitted from the light emitting device 221.

In addition, a hole 222 into which a medicine injection tube 242 of a fixing part 240 described later is inserted may be formed in the placement part 220. The hole 222 may be formed at the center of the inner side of the placing portion 220.

The fixing portion 240 may be combined with the placing portion 220 by snap-in combination. The fixing portion 240 and the placing portion 220 may be formed in a recessed structure in a snap-in coupling manner with each other, respectively.

Also, a fastening structure for fastening the fixing part 240 and the placing part 220 may be formed on an inner sidewall of the fixing part 240 and an outer sidewall of the placing part 220 corresponding thereto. For example, a protrusion 245 may be formed to protrude from an inner sidewall of the fixing portion 240, and a groove 225 corresponding to the protrusion 245 may be formed on an outer sidewall of the mounting portion 220. In this regard, when the fixing part 240 and the placing part 220 are snap-coupled with each other, the protrusion 245 of the fixing part 240 is fastened and fixed to the groove 225 of the placing part 220, whereby the fixing part 240 and the placing part 220 can be coupled with each other.

A plurality of pipes, for example, an inhalation pipe 241 and a drug injection pipe 242, connected to the outside, that is, the main unit 100, may be formed at the fixing portion 240, respectively.

One side of the suction pipe 241 may be connected to the suction part 121 of the body unit 100, and the other side may extend to one end of the fixing part 240 adjacent to the outer sidewall of the placing part 220. The suction pipe 241 can change the interior of the needle unit 200 according to the operation of the suction unit 121, in other words, can change the pressure to the space inside the guide 250, which will be described later, according to the operation of the suction unit 121.

The drug injection tube 242 may have one side connected to a discharge port (not shown) of the drug container 300 coupled to the body unit 100 and the other side extended to be inserted into the hole 222 of the placement unit 220. When the medicine injection tube 242 may change the internal pressure of the needle unit 200 according to the operation of the pumping part 121, the medicine discharged from the medicine container 300 may be supplied between the inner side surface of the placing part 220 and the needle rollers 210. On the other hand, the drug supplied from the drug injection tube 242 adheres to the outer peripheral surface of the needle roller 210, and the drug can flow along the outer peripheral surface of the needle roller 210 and be absorbed into the skin of the user.

The spring 230 may be coupled in a form of a drug injection tube 242 surrounding the fixing portion 240. The spring 230 provides an elastic force to the placing part 220 toward the upper side, in other words, toward the skin direction of the user. In contrast, even if the needle unit 200, which is in contact with the skin of the user, is pressed downward, i.e., in the direction of the body unit 100, the needle unit 200 can be attached to the skin of the user to the maximum extent by the elastic force applied by the spring 230.

The guide 250 may be coupled to one end of the fixing part 240 and contact the skin of the user. The guide 250 may have a hollow cylindrical shape, but is not limited thereto.

The needle roller 210 placed on the placing portion 220 may be received inside the guide 250. The guide 250 may suck and swell the skin of the user to the inner space by a pressure change based on the operation of the suction part 121 of the body unit 100. Thereby, the raised skin may be pierced by the plurality of microneedles 211 of the needle roller 210 inside the guide 250.

Further, a reflective material (not shown) may be coated on the inner wall of the guide 250. In contrast, the guide 250 may reflect red light emitted from the light emitting device 221 of the placing part 220 by the second current output in the body unit 100 through the reflective substance of the inner sidewall and concentrate on the skin of the user.

As described above, the needle unit 200 of the present embodiment can be detachably coupled to the first coupling portion 110 of one side of the body unit 100. Such a needle unit 200 may pierce the skin of a user according to the control of the body unit 100, inject a medicine into the pierced hole, and apply electrical and optical stimuli to the skin.

Further, the needle roller 210 of the needle unit 200 may be in a spherical shape, and thus may freely rotate and move in any direction in the skin of a user, thereby improving convenience and effectiveness of skin surgery such as skin puncture, drug injection, electrical stimulation, and light stimulation.

In the present invention, the detachable skin surgery device may be configured by a needle unit.

Fig. 7 is an exploded perspective view of a disassembled skin-surgery device according to another embodiment of the present invention, and fig. 8 is a sectional view taken along line i-i' after the disassembled skin-surgery device of fig. 7 is combined.

Referring to fig. 7 and 8, the skin surgery apparatus 400 of the present embodiment can be detachably coupled to a container 500 storing a medicine 501 for improving and treating the skin. The skin surgery device 400 can receive a drug 501 from a container 500 and inject it into the inside of the skin of a user.

To this end, the skin surgery apparatus 400 of the present embodiment may include: a coupling unit 410 coupled to the injection port 510 of the container 500; a needle roller 420 combined with the combining unit 410 and contacting the skin of the user; and a protective cover 430 coupled to an outer side of the coupling unit 410 to protect the coupling unit 410 and the needle roller 420.

In the needle roller 420 of the present embodiment, a plurality of micro needles (micro needles) in the form of protruding balls may be formed on the outer circumferential surface. Such a needle roller 420 is freely rotated in any direction, for example, in a 360-degree direction in a state of being in contact with the skin of the user, and pierces the skin of the user by a predetermined depth through the needle. At the same time, the needle roller 420 may inject the medicine 501 provided through the coupling unit 410 into the inside of the skin of the user. Hereinafter, such a needle roller 420 will be described in detail with reference to the drawings.

The coupling unit 410 of the skin surgery device 400 may include: a coupling portion 411 coupled to the inlet 510 of the container 500; a storage part 413 for temporarily storing the medicine 501 supplied from the coupling part 411; and a receiving portion 415 coupled to the needle roller 420.

Such a coupling unit 410 may have various forms according to the shape of the injection port 510 of the container 500. In this embodiment, the coupling unit 410 is coupled to surround the outside of the injection port 510 of the container 500, but the present invention is not limited thereto.

The coupling portion 411 of the coupling unit 410 may be coupled to surround the outside of the injection port 510 of the container 500. In contrast, the inner surface of the coupling portion 411 and the outer surface of the injection port 510 of the container 500 corresponding thereto may be respectively formed with a screw thread and a screw groove, so that the coupling portion 411 and the container 500 may be screw-coupled to each other.

Such a coupling portion 411 may have a hollow structure to allow the transfer of the medicine 501 flowing from the container 500 through the injection port 510 to the storage portion 413.

The storage part 413 may be formed at one side of the combining part 411. The storage part 413 may be a hollow type, and may temporarily store the medicine 501 transferred from the combining part 411.

The placement part 415 may be formed at one side of the storage part 413. The placing portion 415 may have a hemispherical shape with an upper end open and a lower side concave.

A needle roller 420, which will be described later, can be inserted and placed inside the placement section 415. In this case, a portion corresponding to half of the needle roller 420 may be placed on the placing portion 415. In contrast, the skin of the user can contact the needle roller 420 exposed to the outside from the placement portion 415.

Further, a hole 416 for supplying the medicine 501 temporarily stored in the storage part 413 to the outer peripheral surface of the needle roller 420 may be formed inside the placement part 415. The hole 416 may correspond to a central portion of the inner side surface of the placement portion 415.

The inner diameter of the upper end opening of the placement part 415 may be smaller than the outer diameter of the needle roller 420. In contrast, when the needle roller 420 is inserted into the placing portion 415, both side portions of the upper end opening portion can be expanded to a predetermined degree. When the needle roller 420 is inserted through the upper end opening, a force is generated to restore both side portions of the upper end opening to the original positions, for example, in the direction of the needle roller 420. Therefore, the needle rollers 420 can be fixed to both sides of the upper end opening of the placement portion 415, thereby preventing separation from the placement portion 415.

The needle roller 420 may be in a spherical state. The needle roller 420 may be placed on the placing portion 415 of the coupling unit 410 and may be freely rotated in a direction of 360 degrees on the skin of a user.

The needle roller 420 may include a plurality of microneedles 423 protrudingly formed at an outer circumferential surface thereof and a plurality of guide protrusions 425. When the needle roller 420 comes into contact with the skin of a user, the plurality of microneedles 423 may pierce the skin. When the needle rollers 420 rotate, the plurality of guide protrusions 425 may prevent the tips of the plurality of microneedles 423 from being damaged due to the inner side surfaces of the placement portions 415.

Fig. 9 is a view showing an embodiment of the needle roller of fig. 7.

Referring to fig. 9, the needle roller 420 of the present embodiment may have a spherical shape and may be placed inside the placing portion 415 of the coupling unit 410. However, approximately half of the needle roller 420 may be placed on the inner surface of the placement portion 415, and the remaining area may be exposed to the outside through the upper end opening of the placement portion 415.

The needle roller 420 has a plurality of microneedles 423 and a plurality of guide projections 425 formed along the outer circumferential surface 420a thereof.

The plurality of microneedles 423 may be formed at predetermined intervals on the outer circumferential surface of the needle roller 420. The plurality of microneedles 423 may be protrusively formed in a conical shape having a triangular shape in cross section. The height of the microneedles 423, that is, the height d1 from the outer circumferential surface 420a of the needle roller 420 to the tip of each microneedle 423 may be 0.2 to 0.5 mm.

When the exposed portion of the needle roller 420, that is, the portion exposed in the upper end opening portion of the placement portion 415, is rotated while being in contact with the skin of the user, the plurality of microneedles 423 can penetrate the skin of the user at a predetermined depth. In contrast, the drug 501 supplied to the outer circumferential surface 420a of the needle roller 420 through the coupling unit 410 can flow into the skin punctured by the microneedles 423 and be injected.

The plurality of guide projections 425 may be formed on the outer circumferential surface of the needle roller 420 at predetermined intervals. In this case, a plurality of guide protrusions 425 may be formed between the plurality of microneedles 423. The guide projections 425 are arranged on the outer peripheral surface 420a of the needle roller 420 at predetermined intervals in accordance with a regular arrangement pattern, for example, in at least one of the lateral direction, the longitudinal direction, and the oblique direction of the outer peripheral surface 420 a.

The section of the plurality of guide protrusions 425 may be protrusively formed in a hemispherical shape having a semicircular form. In this case, the height d2 from the outer circumferential surface 420a of the needle roller 420 to the tip of each guide protrusion 425 may be 0.3 to 0.6 mm.

As described above, in the needle roller 420 of the present embodiment, the height of the plurality of guide protrusions 425 may be greater than the height of the plurality of microneedles 423, and the inner side surface of the placement portion 415 is in contact with only the plurality of guide protrusions 425, whereby, when the needle roller 420 rotates, the respective ends of the plurality of microneedles 423 may be prevented from being damaged due to the inner side surface of the placement portion 415.

Meanwhile, the plurality of guide protrusions 425 may have a hemispherical shape, and thus, when the needle rollers 420 rotate, the needle rollers 420 may smoothly rotate by reducing a frictional force between the inner side surfaces of the receiving portions 415 and the outer circumferential surfaces of the needle rollers 420.

In the needle roller 420 of the present embodiment, the plurality of guide projections 425 are arranged at predetermined intervals, so that the medicine 501 supplied to the needle roller 420 can be uniformly applied to the outer peripheral surface 420a of the needle roller 420 via the inner surface of the placement portion 415. In contrast, the needle roller 420 can pierce the skin of the user with the plurality of microneedles 423 and inject a predetermined amount of the drug 501 into the skin.

The plurality of microneedles 423 and the guide protrusion 425 of the needle roller 420 may be integrally formed with the needle roller 420.

The needle roller 420 may be formed of a conductive material, for example, a metal material such as gold, silver, aluminum, or lead, by die casting (die casting). Also, the needle roller 420 may be formed by plastic injection molding. In this case, the injection-molded plastic needle roller 420 and the plurality of microneedles 423 and guide protrusions 425 of the outer circumferential surface thereof may be plated.

As described above, the detachable skin surgery apparatus 400 according to the present invention can puncture the skin and inject a drug or the like by freely rotating and moving the needle roller 420 in the direction of the skin of the user, thereby improving the convenience and effectiveness of the skin surgery.

Meanwhile, the detachable skin surgery apparatus 400 of the present invention may form a plurality of guide protrusions 425 having a height greater than that of the plurality of microneedles 423 on the outer circumferential surface of the needle roller 420, and thus, when the needle roller 420 rotates, the microneedles 423 may be prevented from being damaged by the inner surface of the placement portion 415.

Further, the detachable skin surgery apparatus 400 of the present invention can be used by being coupled to the outside or inside of the injection port 510 of the container 500 for storing the medicine, so that the medicine can be injected into the skin through the needle roller 420 by piercing the skin with the needle roller 420.

Therefore, the detachable skin surgery apparatus 400 of the present invention can be used once with a simplified internal structure compared to the conventional one, and can prevent the needle rollers and the like from being contaminated.
