Description

Skin treatment device and needle unit for skin treatment device {SKIN TREATMENT APPARATUS AND NEEDLE UNIT FOR THE SAME}

The present disclosure relates to a skin treatment device and a needle unit therefor.

In recent years, as tattoos and semi-permanent makeup are popular, there is a demand for the development of a technology for accurately penetrating a colorant or drug into a desired area in a desired shape and size.

A needle is used to infiltrate the skin with colorants or drugs for cosmetic tattoos or semi-permanent makeup. For example, in the case of semi-permanent makeup procedures such as eyebrows, lips, eyelines, and scalp, the skin is perforated with a needle and a colorant or drug is penetrated into the perforated skin.

In general, a skin treatment apparatus includes a rod for convenient use by fixing a needle and a clamp for detachably coupling the needle to the rod. Needles for tattoo or semi-permanent makeup procedures are usually disposable, and the operator replaces a new needle in the clamp and uses it.

Various types of needles are being researched for more effective procedures, and development of a device for appropriately responding to new needles or surgical techniques is required. Accordingly, improving the conventional needle or surgical device can provide many advantages to the user.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the following examples are only preferred examples of the present invention, and the present invention is not limited to the following examples.

1 shows the configuration of a skin treatment apparatus according to the present embodiment.

As shown, the skin treatment apparatus 100 of the present embodiment may include a mounting part 300 that is provided at the front end of the rod 200 and detachably couples the needle unit 300 for skin treatment.

The rod 200 is for gripping by the operator by hand, and may be a cylindrical pipe structure extending elongated. In addition to the simple structure in the form of a cylindrical pipe, the rod may have various structures such as an electric vertical reciprocating motion and a vibration structure by a vibrating body having an eccentric shaft. The rod is elongated and can be applied to any structural surface that can be gripped and used by the operator.

The needle unit 300 is coupled to the rod 200 via the mounting part 400. Accordingly, the operator can incise the skin and inject the solution into the skin by pressing and moving the needle unit 300 installed at the tip of the rod 200 to a desired part of the skin while holding the rod 200 like a pencil.

The mounting part 400 may have a structure that can be separated from the rod 200. In addition to this structure, the rod 200 may be integrally formed on the mounting part 400. In the case of a structure in which the mounting part 400 is separated from the rod 200, the mounting part 400 may be fastened to various rods 200 and used. Accordingly, by combining the mounting part 400 of the present embodiment to the rod 200 used in the related art, skin treatment may be performed using various types of needles and treatment methods.

In this embodiment, the mounting part 400 has a structure in which the needles can be separated and coupled more simply and conveniently. The structure of the mounting part 400 will be described in detail later.

2 to 4 show the structure of the needle unit according to the present embodiment.

The needle unit 300 of this embodiment has a structure capable of supplying a solution to the needle by itself. To this end, the needle unit 300 may include a needle 310 for cutting skin, a support member 320 provided with a shaft member 322, and an injection plate 330 for supplying a solution. The needle 310, the support member 320, and the injection plate 330 are combined to form one unit 300. Accordingly, the solution accommodated in the injection plate 330 is continuously supplied to the needle 310 during the procedure, so that the procedure can be performed more conveniently.

The needle 310 of this embodiment has a structure in which a needle is formed along an outer circumferential surface in the form of a circular disk. A central hole 316 through which the needle rotation shaft passes may be formed in the center of the needle 310. That is, as shown in Fig. 2, the needle 310 has a central hole 316 formed in the center so that the shaft member 322 of the support member 320 penetrates, so that the shaft member 322 is rotated using the shaft member 322 as a rotation axis. The disk 312 may include a plurality of needles 314 formed at intervals along the outer circumferential surface of the disk 312 and protruding in a radial direction to cut the skin. The needle 310 is inserted into the shaft member 322 and is rotatably supported by the support member 320. Since the center hole 316 of the needle has a relatively larger inner diameter than the shaft member 322, the needle can freely rotate around the shaft member. Accordingly, when the needle unit 300 is mounted on the skin treatment apparatus to move the needle along the skin, the needle 310 is moved while rotating with the shaft member 322 as a rotation axis. In this process, the needle 314 formed along the outer circumferential surface of the needle 310 cuts the skin.

In addition to the needles having the above structure, various types of needles may be mounted on the needle unit 300. For example, the structure of the needle can be variously deformed, such as a needle having a flow path formed on the surface or a needle having an uneven portion formed in a center hole to apply vibration to the needle.

At the center of the support member 320, a shaft member 322 is provided that passes through the center hole 316 of the needle 310 and forms the center of rotation of the needle. The support member 320 fixes the injection plate 330 and rotatably supports the needle 310. The support member 320 supports the shaft member 322 and is disposed on both sides of the needle 310 to act as a stopper to prevent the needle or the injection plate from being removed from the shaft member.

As shown in FIG. 2, two support members 320 form a pair and are disposed on both sides of the needle 310, respectively. The shaft member 322 is installed between the centers of the two support members 320.

In this embodiment, a shaft member 322 is formed protruding from one support member 320 of the pair of support members 320, and a groove portion 324 into which the shaft member 322 is inserted into the other support member 320 Can be formed. Accordingly, the two supporting members 320 may be coupled with the shaft member 322 inserted into the groove 324 with the needle 310 and the injection plate 330 interposed therebetween. The shaft member 322 may be fitted and fixed to the groove portion 324. Alternatively, the shaft member may be coupled by a screw method to a groove portion in which a male screw is formed at a tip end and a female screw is formed, or a stepped portion is formed and inserted into the groove portion in a one-touch manner.

The spacing between the opposite inner surfaces of the support member 320 is sufficient as long as the needle 310 rotates freely between the support members 320 and makes contact with the injection plate 330 with a gap. By appropriately setting the depth of the groove portion 324 or the length of the shaft member 322, a gap between the inner surfaces of the support member 320 facing each other may be appropriately formed. Accordingly, while the needle 310 is freely rotated, the solution may be smoothly supplied from the injection plate 330 toward the needle.

A coupling portion for coupling the shaft member 322 to the skin treatment apparatus may be formed on the outer surface of the support member 320. The coupling portion may be formed along the axial center of the shaft member 322. In this embodiment, the coupling portion may be a support shaft 326 protruding outward from the support member 320. Accordingly, the needle unit 300 may be detachably fixed by forming a groove in which the support shaft 326 is inserted in the skin treatment apparatus.

In addition to this structure, in another embodiment, the coupling portion may include a recess formed in the support member. In the case of a structure in which a concave groove is formed as a coupling part, the needle unit may be detachably fixed by forming a protrusion to be fitted in the concave groove in the skin treatment apparatus.

In this embodiment, the shaft member 322 may be formed in a polygonal cross-sectional structure. For example, the shaft member 322 may be formed in a rectangular cross-sectional shape. Compared to the size of the shaft member 322, the central hole 316 of the needle 310 has a relatively large inner diameter, so even if the shaft member 322 is formed in a polygonal cross-sectional structure, the needle 310 is a shaft member 322 ) Can be rotated freely.

The injection plate 330 may be coupled to the shaft member 322 and disposed between the support member 320 and the needle 310, and may have a structure in which a supply part for supplying a solution to the needle 310 is formed on the surface.

In this embodiment, the injection plate 330 may be formed in a disk shape. The thickness of the injection plate 330 may be formed in various sizes. A fitting hole 332 through which the shaft member 322 is inserted is formed in the center of the injection plate 330. The fitting hole 332 formed in the injection plate 330 may be formed in a polygonal cross-sectional structure corresponding to the cross-sectional shape of the shaft member 322.

As shown in FIG. 3, in this embodiment, the fitting hole 332 may be formed in a rectangular cross-sectional shape like the cross-sectional shape of the shaft member 322. Accordingly, the injection plate 330 is inserted into the shaft member 322 to limit rotation. Therefore, in the needle unit 300, the needle 310 is rotated around the shaft member 322, and the injection plate 330 is fixed to the shaft member 322 and is not rotated. In this way, the injection plate 330 is fixed, and the needle 310 rotates freely, so that the needle 310 and the injection plate 330 move relative to each other. Accordingly, while the needle 310 and the injection plate 330 cross each other, the front surface of the needle 310 passes through the supply portion of the injection plate 330. Accordingly, the solution accommodated in the supply unit of the injection plate 330 can be evenly supplied to the front surface of the needle 310.

The supply unit may include a hole 334 formed in the injection plate 330 and capable of receiving a solution. The hole 334 is formed through the injection plate 330 to supply the received solution toward the needle. The hole 334 may form a hopper shape having an inclined inner surface such that the width gradually narrows from the outside toward the needle.

The number or size of the holes 334 can be variously modified. At least one or more ribs 336 for holding the solution may be further formed in the hole 334. The ribs 336 may be formed to extend between the inner surfaces of the holes 334. The plurality of ribs 336 may be formed in various shapes within the hole 334 such as a cross shape or a lattice shape. The rib 336 is in contact with the solution contained in the hole 334 and prevents the solution from rushing out. Therefore, the solution accommodated in the hole 334 does not flow out directly from the hole 334 to the needle 310 in a state adhered to the rib 336, but continues to stay in the hole 334 and flows out little by little.

The hole 334 may be formed at an appropriate position on the front surface of the injection plate 330 according to the size of the needle 310 in the shape of a circular disk. The solution supplied to the hole 334 comes into contact with the surface of the needle 310 and is deposited on the surface of the needle. As the needle is rotated, the solution is gradually discharged from the hole 334 while being buried on the surface of the needle 310. That is, as the needle 310 rotates around the shaft member 322, the solution is evenly spread over the disk-shaped needle 310. The solution buried on the surface of the needle 310 is moved to the needle 314 at the tip of the needle as the needle rotates and penetrates into the cut skin through the needle.

Needle unit 300 of this embodiment, by supplying a solution into the hole 334 of the injection plate 330, the solution is separately prepared in a container, and during the procedure, the need to move the needle to the container and dip it into the solution is troublesome. Can be reduced. In addition, as the solution is accommodated in the hole 334, evaporation of the solution is minimized, thereby reducing the amount of the solution used.

The solution used for skin treatment is difficult to use because it hardens rapidly and has a property of rapidly increasing viscosity. In this embodiment, friction is generated between the injection plate and the needle while the disk-shaped needle rotates. Accordingly, heat due to friction is applied to the solution, so that it is possible to minimize hardening of the solution. Accordingly, the device prevents the solution from hardening even when used for a long time, thereby reducing the amount of the solution used and performing a smooth procedure.

As such, the needle unit 300 according to the present embodiment rotatably supports the needle 310 by itself and can supply a solution through the injection plate 330. The needle unit 300 is mounted on various treatment apparatuses, and through this, the user can perform the treatment more conveniently while minimizing the trouble of having to bury the solution in a cumbersome manner.

The skin treatment apparatus 100 of the present embodiment includes a mounting part 400 for detachably fixing the needle unit 300. The mounting part 400 can easily and quickly clamp and fix the needle unit 300 or separate and remove the used needle unit 300 simply and quickly.

5 shows a needle unit according to another embodiment, and the needle unit shown in FIG. 5 has a structure capable of supplying a solution through a support member without having an injection plate. The embodiment shown in Fig. 5 is the same as the embodiment shown in Figs. 2 to 4 except that the solution is supplied from the support member to the needle without an injection plate. Accordingly, the same reference numerals are used for the same configuration, and detailed descriptions thereof are omitted.

As shown in FIG. 5, the needle unit 300 of this embodiment may include a skin incision needle 310, a shaft member 322, and a support member 320 for supplying a solution to the needle. . The needle 310 and the support member 320 are combined to form one unit 300. Accordingly, the solution accommodated in the support member 330 is continuously supplied to the needle 310 during the procedure, so that the procedure can be performed more conveniently.

The spacing between the opposite inner surfaces of the support member 320 is sufficient as long as the needle 310 rotates freely between the support members 320 and makes contact with the support member 320 with a gap. By appropriately setting the depth of the groove portion 324 or the length of the shaft member 322, a gap between the inner surfaces of the support member 320 facing each other may be appropriately formed. Accordingly, while the needle 310 is freely rotated, the solution can be smoothly supplied from the support member 320 toward the needle.

As shown in FIG. 5, a supply unit for supplying a solution to the needle 310 may be formed on the surface of at least one of the support members 320 of the present embodiment.

The support member 320 is fixed to the mounting portion, and the needle 310 rotates freely, so that the needle 310 and the support member 320 move relative to each other. Accordingly, while the needle 310 and the support member 320 cross each other, the front surface of the needle 310 passes through the supply portion of the support member 320. Accordingly, the solution accommodated in the supply portion of the support member 320 can be evenly supplied to the front surface of the needle 310.

The supply unit may include a hole 328 formed in the support member 320 and capable of receiving a solution. The hole 328 is formed through the support member 320 to supply the received solution toward the needle. The hole 328 may form a hopper shape having an inclined inner surface such that the width gradually narrows from the outside toward the needle.

The number or size of the holes 328 can be variously modified. At least one or more ribs (not shown) for holding the solution may be further formed in the hole 328. The hole 328 may be formed at an appropriate position on the front surface of the support member 320 according to the size of the needle 310 in the form of a circular disk. The solution supplied to the hole 328 contacts the surface of the needle 310 and is deposited on the surface of the needle. As the needle rotates, the solution is gradually discharged from the hole 328 as it is buried on the surface of the needle 310 and is evenly spread over the needle 310. The solution buried on the surface of the needle 310 is moved to the needle 314 at the tip of the needle as the needle rotates and penetrates into the cut skin through the needle.

Hereinafter, a mounting unit according to the present embodiment will be described with reference to FIGS. 6 and 7.

The mounting part 400 is rotatably coupled through the hinge shaft 420 and a pair of tongs members 410 for fastening or separating the needle by opening or constricting one end around the hinge shaft 420, a clamp member It may include a clamping portion provided at the tip of 410 and coupled to the needle, and an elastic member 440 installed on the hinge shaft 420 to apply an elastic force so that the pair of tongs members 410 are closed.

In this way, by elastically opening or closing the clamp member 410, the needle unit 300 can be more easily fixed or separated and removed. Accordingly, it is possible to minimize the time and effort required for the operation by simply replacing the needle unit 300.

The clamp member 410 is a structure in the form of a bar that is elongated, and its length or shape can be variously deformed. The two clamp members 410 forming a pair are disposed opposite to each other, and a shaft bracket 412 into which the hinge shaft 420 is fitted may be formed to protrude on an inner surface facing each other. Accordingly, the hinge shaft 420 is inserted while the shaft bracket 412 is engaged so that the two clamp members 410 are rotatably coupled.

In this embodiment, the elastic member 440 may be formed of a coil spring. The coil spring is installed by being fitted to the hinge shaft 420, and both ends are extended to the two clamp members 410 to apply an elastic force to the clamp member 410. The elastic member 440 applies an elastic force so that the pair of clamp members 410 clamp and fix the needle unit 300.

One of the two clamp members 410 is formed with a clamping part at one end of the hinge shaft 420 as the center, and a pressing plate 450 for spreading the clamp member 410 at the opposite end. I can. Accordingly, the user can easily open the clamp member 410 by applying a force to the pressing plate 450.

In addition, of the two clamping members 410, the other clamping member 410 has a clamping part formed at one end of the hinge shaft 420, and the mounting part 400 is installed on the rod 200 at the opposite end. The fastening bar 460 may be formed.

The fastening bar 460 may be formed to protrude from the tip of the clamp member 410, and may have a structure in which a male screw fastened to a female screw hole (refer to 210 of FIG. 1) of the tip of the rod 200 is formed on the surface. Accordingly, the mounting part 400 may be detachably coupled to the rod 200 through a fastening bar.

The needle unit 300 is coupled to a clamping portion formed at the tip of the clamp member 410 and fixed to the mounting portion 400. The clamping part of the present embodiment may include insertion grooves 430 respectively formed at opposite ends of the clamp member 410 so that the support shaft 326 formed on the support member 320 of the needle unit 300 is fitted. The insertion groove 430 forms a groove structure depressed inward.

In addition to the above structure, in the case of the structure in which the groove is formed in the support member of the needle unit, the clamping part may have a structure in which the projections are formed at the opposite ends of the clamp member so as to be fitted into the groove. Accordingly, in this structure, the needle unit may be fixed to the mounting portion while the protrusion of the clamp member is fitted into the groove of the needle unit.

As such, the mounting part 400 of the present embodiment is able to more conveniently fix the needle unit 300 by opening the clamp member 410.

7 shows a state in which the needle unit 300 is coupled to the mounting part 400. As shown in FIG. 7, the clamp member 410 is closed by the elastic force of the elastic member 440. In this state, when the user applies a force to the pressing plate 450 of the clamp member 410, the elastic member 440 is elastically compressed and the clamp member 410 that was closed is opened. Accordingly, when the needle unit 300 is positioned between the insertion grooves 430 formed at the tip of the opened clamp member 410 and the force applied to the pressing plate 450 is removed, the clamp member 410 is retracted and the needle unit ( 300) It is fixed. That is, when the user does not apply a force to the pressing plate 450, the clamp member 410 is pressed to its original state by the elastic restoring force of the compression member 322, which has been elastically compressed, and is closed. Accordingly, while the support shaft 326 of the needle unit 300 is inserted into the insertion groove 430 formed at the tip of the clamp member 410, the clamp member 410 pressurizes and fixes the needle unit 300.

Accordingly, in the present embodiment, the needle unit 300 can be easily fixed to the mounting portion 400 by simply opening the clamp member 410, or the used needle unit 300 can be separated and removed from the mounting portion 400.

8 shows another embodiment of the mounting portion.

Since the mounting portion 400 of the present embodiment is the same as the configuration of the mounting portion 400 described above, except for the structure for coupling with the needle 310, the same reference numerals are described for the same configuration below, and detailed description thereof Is omitted. As mentioned above, the needle may also be a disk-shaped needle having a needle formed on the outer circumferential surface.

As shown in Fig. 8, the mounting part 400 of this embodiment has a structure that can be used by attaching and detaching only the needle 310.

To this end, the mounting part 400 of the present embodiment includes a clamp member 410, a clamping part, and an elastic member 440, and the clamping part is a coupling groove formed in the clamp member 410 on one side of the clamp member 410 ( 470), is formed protruding from the other clamp member 410, is fitted into the coupling groove 470 when the clamp member 410 is closed, and penetrates the central hole 316 of the needle 310 to penetrate the needle 310 It may include a protruding bar 472 rotatably supported.

The inner surface facing the clamp member 410 of the present embodiment is a surface in contact with the needle 310 and may be formed in a smooth flat shape so as not to interfere with the needle.

The protruding bar 472 forms the axis of rotation of the needle 310. The needle 310 is rotated around the protruding bar 472 as an axial center. The needle 310 may be freely rotated between the two clamp members 410.

The protruding bar 472 may have a circular cross-sectional structure or a polygonal cross-sectional structure such as a square or pentagon. Since the size of the protruding bar 472 is relatively small compared to the size of the center hole 316 of the needle 310, the needle 310 is axially formed by the protruding bar 472 regardless of the cross-sectional shape of the protruding bar 472. Can be rotated freely.

In the case of a structure in which the protruding bar 472 is formed in a polygonal cross-sectional structure, in addition to the rotatable disk-shaped needle 310, a needle extending in a strip shape and having a needle formed at the tip may be fixed to the mounting portion. For example, a square hole is formed in a strip-shaped needle body, and the protruding bar may be formed in a square cross-sectional structure having a corresponding size so that it can be fitted into the square hole. Thus, it is possible to easily couple or separate the needle into the mounting portion by inserting the strip-shaped needle into the protruding bar. By coupling the square hole of the needle to the square protruding bar, the strip-shaped needle can be fixedly installed on the mounting portion in a non-rotating state.

In the embodiment shown in FIG. 8, when the clamp member 410 is closed, the protruding bar 472 is inserted into the coupling groove 470 and the needle 310 fitted to the protruding bar 472 is inserted into the protruding bar ( 472).

The gap between the two clamp members 410 is maintained at which the needle 310 can be rotated. When the clamp member 410 is closed and the protruding bar 472 is completely fitted in the coupling groove 470, the gap between the clamp members 410 may be formed to be greater than or equal to the thickness of the needle 310. Accordingly, even when the tongs member 410 is completely closed, the needle 310 may freely rotate around the protruding bar 472 as a rotation axis without interfering with the tongs member 410.

In this embodiment, the mounting unit 400 may further include a supply unit for supplying a solution to the needle 310. Accordingly, it is possible to provide a solution directly to the needle 310 through the mounting part 400. The supply unit may include a solution receiving groove 480 formed on one side of the clamp member 410 to form a space in which the solution is accommodated, and a supply hole 482 through which the solution is discharged through the needle 310 is formed at the bottom. have.

The solution receiving groove 480 may form a hopper shape with an inclined inner surface so that the width gradually narrows toward the supply hole 482 from the outside of the end.

The solution supplied to the solution receiving groove 480 contacts the surface of the needle 310 through the supply hole 482 at the bottom and is buried on the surface of the needle 310. As the needle 310 is rotated, the solution is gradually discharged while being buried on the surface of the needle 310 through the supply hole 482 in the solution receiving groove 480. Accordingly, even if only the needle 310 is directly coupled to the mounting part 400, the solution can be supplied to the needle 310.

Accordingly, while the needle 310 is rotated around the protruding bar 472, the solution discharged through the supply hole 482 is evenly applied to the entire disk-shaped needle 310. The solution buried on the surface of the needle 310 is moved to the needle at the tip of the needle as the needle rotates, and penetrates into the cut skin through the needle.

As described above, the treatment apparatus of the present embodiment can be used by simply replacing various types of needles such as a needle unit, a circular disk-shaped needle, and a strip-shaped needle by simply opening the tongs member.

As described above, exemplary embodiments of the present invention have been shown and described, but various modifications and other embodiments may be made by those skilled in the art. These modifications and other embodiments are all considered and included in the appended claims and will not depart from the true spirit and scope of the present invention.
