Description

Apparatus For Treating Skin

The present invention relates to a complex device for skin that the needle can be used to engrave a tattoo on the skin by automatically reciprocating straight line, or to regenerate the skin, and more specifically, the inclined guide on the inner circumferential surface of the cylindrical cam rotated by the driving motor operation The cam block, which forms a surface and is positioned inside the cylindrical cam and is mounted on one side of a roller rotatable along the inclined guide surface, operates the needle up and down through the connecting lever so that the needle does not vibrate left and right, and the straightness is greatly improved. Or it relates to a complex device for skin that can prevent damage to the skin during the skin regeneration procedure, minimize the pain and can be utilized for multi-purpose.

In general, a tattoo device refers to a device that uses a tattoo ink and a needle to express a pattern or a picture such as a predetermined symbol, letter, or figure on a human skin.

Such a tattoo device, the needle is automatically reciprocating back and forth for the convenience of the tattoo work, the tattoo ink to descend the needle while the needle is reciprocating, and when the needle pierces the human skin to a certain depth A predetermined pattern can be expressed on the skin of a person as intended by a tattoo operator.

Such conventional tattoo apparatuses mostly use the power of the driving motor to advance the needle, but most of the tattoo apparatus uses the elastic restoring force of the spring.

Therefore, such a conventional tattoo device has a problem in that the elastic restoring force of the spring is changed when used for a predetermined period so that the protruding needle does not retreat or takes a long time to retreat. As such, if the needle does not reciprocate correctly, the tattoo cannot be drawn accurately.

In order to solve such a problem, the "tattoo apparatus" of patent registration No. 10-0789398 is proposed.

Such a conventional technology is provided with a drive unit installed inside the case, such as a pen, a cam unit for converting the rotation of the drive motor to a linear reciprocating motion, and the needle is installed to move forward or backward in conjunction with the link.

And such a cam unit is a structure including a cam connected to the drive motor via a bevel gear pair to rotate in operation of the drive motor and a cam follower for a linear reciprocating motion in accordance with the rotation of the cam.

Therefore, such a conventional tattoo apparatus is intended to ensure the straightness by installing the contact point of the cam and the cam follower in a straight line with the needle.

However, this conventional technique generates vibration in the process of the movement of the cam and the cam follow through the link.

As a result, such vibrations cause the needle to shake left and right so that the forward and backward trajectories of the needle are different when the tattooer is working on the tattoo, thereby still causing skin damage and pain.

As another structure, the "liquid penetration device for skin" of Patent Registration No. 10-0922138 has been proposed.

Such a conventional technique includes a body having a drive device having a drive motor, a cam member rotated by the drive device, and a connecting member reciprocally driven by the cam member, the needle being detachable at the tip of the body part. The unit is mounted. In addition, the needle unit has a structure including a rubber member for preventing blood and pigments introduced into the needle unit after being discharged from the skin of the subject during the procedure and flowing into the body portion.

This conventional technique uses a cam member and a connecting member to convert the rotational operation of the drive motor into a linear motion of the needle, but it still uses a spring to return the needle, which does not guarantee reliable operation for a long time. It does not have a problem.

On the other hand, unlike such a tattoo device, a skin regeneration device for forcibly stimulating or hurting the skin to activate the skin regeneration is known.

As such a skin regeneration device, for example, a "skin regeneration device using a multi-hole" of Patent Registration No. 10-0910793 is proposed.

The patient's pain can be minimized during the procedure by puncturing the needle at a speed as fast as he can't feel, and most of all, the drug can be applied immediately after drilling a hole in the treatment area compared to the conventional method of applying the drug by hand. The drug penetration effect is very good and can significantly improve the therapeutic effect.

However, such a conventional technique uses an electric motor, a cam, a connecting rod, and a return spring, such that a structure for reciprocating the microneedle is not stable, generates noise, and has a problem of deterioration in durability.

That is, when the second cam member 164b is fitted into the first cam member 164a in a snap fit manner, the upper step 168a of the first cam member 164a and the bottom step of the second cam member 164b are combined. 168b face each other in parallel to form an inclined guide surface 166 on the inner circumferential surface of the cam 162.

Accordingly, the roller 174a of the protrusion 174 located on the side of the cam block 172 is disposed on the inclined guide surface 166 of the cam 162 as shown in FIGS. When 162 rotates, the cam block 172 is converted into linear motion while being pushed back and forth by the inclined guide surface 166.

Meanwhile, the power converter 160 includes three linear guides 180 which prevent the cam block 172 from turning along with the cam 162 while the linear guides 180 are circumferential 120. It is formed on the outer side of the connecting lever 176 at an angle of FIG., The upper end is respectively connected to the lower end of the cam block 172, the first casing 112a through the partition wall 182 formed inside the casing 110 It is connected to the inside of the second casing (112b) from, the lower end is inserted and fixed to the support plate 184 in the inner side of the second casing (112b).

Accordingly, the cam block 172 connected to the straight guide 180 is not rotated together with the rotation of the cam 162, and is pushed in the front and rear linear directions through the roller 174a of the protrusion 174. Along with the push of the same cam block 172, the linear guide 180 and the support plate 184 are also linearly interlocked together.

The connecting lever 176 penetrates the center of the cam block 172, and an upper end thereof is fitted inside an upper bushing 178a rotatably mounted at the center of the inner surface of the cam 162. A part passes through a partition wall 182 disposed at a connection point of the first casing 112a and the second casing 112b through a lower bushing 178b, and a lower end of the supporting plate is connected to the straight guide 180. 184 penetrates and is fixed to the connecting table 186 on the lower side thereof.

Therefore, the connecting lever 176 transfers the linear motion of the cam block 172 to the connecting table 186 as it is, and the lower inner side of the connecting table 186 of the needle 142 embedded in the needle mounting unit 140. The upper side holder 144 is inserted and connected integrally so that the front and rear linear movement of the needle 142 together with the connection lever 176 is performed.

That is, the rotation shaft 124a, the cylindrical cam 162, the cam block 172, the connecting lever 176 and the needle 142 of the drive motor 124 as shown in the assembled state in Figures 3 and 4 , Coaxially arranged with each other, the needle 142 is connected to the front and the rear through the rotation operation of the drive motor 124.

The needle mounting unit 140 is connected to the front side of the casing 110 in which the power converter 160 is built.

The needle mounting unit 140 is connected to the hollow guider 150 through the needle depth adjusting unit 200 to be described later to the front side of the casing 110, such a hollow guider 150 in the front and rear The needle 142 and the holder 144 at the top thereof are located, and when used as a tattoo device, an ink reservoir 152 for supplying ink to the needle 142 is provided inside the hollow guider 150. Formed.

If the present invention is used as a skin regeneration apparatus, instead of the hollow guider 150 as described above, a separate guider (not shown) having a plurality of needles may be used instead as a skin regeneration apparatus.

In addition, the needle depth adjusting unit 200 is formed at the front end of the casing 110 and the connection point formed at the top of the guider 150 of the needle mounting unit 140, and the needle depth adjusting unit 200 is a user. When the rotary dial 202 rotates linearly inside the casing 110 to adjust the bottom protrusion depth of the guider 150 back and forth with respect to the casing 110, and penetrates the bottom of the guider 150 to the lower side. It is configured to adjust the length of the protruding needle 142.

To this end, a scale (not shown) indicating the protrusion length of the needle 142 is displayed on the outer surface of the rotary dial 202, and a reference point (not shown) is displayed on the outer surface of the casing 110 adjacent to the scale. The protruding length of the needle 142 can be easily adjusted by turning the rotary dial 202 while viewing the scale.

As shown in FIG. 2, the needle depth adjusting unit 200 is fixed to the upper jaw 208 by a coupling step 206 formed at the front end of the casing 110. 212 is provided with a plurality of two divided circular members (210a, 210b), respectively, and has a ring-shaped rotary dial 202 coupled to the outer surface of the plurality of two divided circular members (210a, 210b).

The ring-shaped rotary dial 202 as described above allows a plurality of two-part circular members 210a and 210b to be integrally coupled to each other on its inner circumferential surface to function as a female screw.

And the slider 220 extending inwardly of the casing 110 to the upper side of the guider 150 of the needle mounting portion 140 is press-fitted to the upper end of the guider 150 through the slide bushing 222, The leaf spring 224 is fitted therebetween to prevent the guider 150 from being pulled out of the slider 220.

In addition, a male thread 226 is formed on the outer surface of the slider 220. The male thread 226 is screwed to the internal thread 212 of the inner circumferential surface of the two-part circular member 210a or 210b. When the user rotates the rotary dial 202, the slider 220 with the guider 150 on the inside of the casing 110 through the rotation of a plurality of two divided circular members (210a, 210b) coupled thereto. By moving linearly, the bottom protrusion depth of the guider 150 is adjusted back and forth with respect to the casing 110.

At this time, the needle 142 located inside the guider 150 has a lower protrusion depth of the guider 150 because the holder 144 of the upper side thereof is fixedly coupled to the connecting table 186. When it is adjusted back and forth with respect to the casing 110, the result is to adjust the length of the needle 142 penetrating the lower end of the guider 150 to protrude downward, thereby adjusting the depth at which the needle 142 pierces the skin.

The complex device for skin 100 according to the present invention configured as described above is coupled as shown in FIGS. 3 and 4, and casings the rotational force of the driving motor 124 provided in the driving unit 120 behind the casing 110. The power converter 160 inside the 110 is converted into a linear motion and transmitted to the needle 142 provided in the needle mounting unit 140 in front of the casing 110.

In this structure, the rotating shaft 124a, the cylindrical cam 162, the cam block 172, the connecting lever 176 and the needle 142 of the drive motor 124 are arranged coaxially with each other so that the drive motor In the rotation operation of the 124, the needle 142 does not oscillate from side to side, but immediately moves straight forward and backward, thereby greatly improving its straightness.

That is, when the user rotates the rotary switch button 134 of the driving unit 120 and rotates the driving motor 124 at a set rotation speed, as shown in FIG. 4, the rotation shaft 124a of the driving motor 124. The cylindrical cam 162 of the power converter 160 connected through the socket 124b rotates at a predetermined speed.

At this time, the inclined guide surface 166 formed on the inner circumferential surface of the cylindrical cam 162 is rotated. As such, the inclined guide surface 166 rotates to convert the cam block 172 into linear motion through the roller 174a.

That is, the cam block 172 tries to rotate like the cylindrical cam 162 due to the roller 174a caught on the inclined guide surface 166 of the cylindrical cam 162, but the three linear guides 180 are located on the lower side thereof. Is coupled to penetrate the partition wall 182 of the casing 110 and is connected to the backing plate 184, and thus cannot be rotated together with the cylindrical cam 162, and instead the roller 174a is the upper step of the inclined guide surface 166. It is converted into a linear reciprocating motion while being pushed back and forth by 168a and the lower stepped step 168b.

Accordingly, the cam block 172 linearly reciprocating thus linearly reciprocates the connecting lever 176 at its lower end, and the connecting lever 176 penetrates the center of the support plate 184 to which the linear guide 180 is fixed. By being fixed to the upper end of the connecting rod 186, the connecting rod 186 is simultaneously linearly reciprocated, and the needle 142 is linearly reciprocating through the holder 144 fixed to the connecting rod 186.

Such a linear reciprocation of the cam block 172 is shown in detail with reference to FIGS. 5A and 5B.

That is, when the roller 174a is located on the upper side of the inclined guide surface 166 during the rotation of the cylindrical cam 162, the cam block 172 is moved backward, and the cylindrical cam 162 is moved. When the roller 174a is further rotated and positioned at the lower side of the inclined guide surface 166 as shown in FIG. 5B, the guider 150 positioned in front of the casing 110 is moved forward by moving the cam block 172. The needle 142 protrudes toward the lower side through the lower end of the needle, and the needle 142 sticks the skin by the length of the protrusion.

Therefore, since the driving motor 124 continuously rotates at high speed, the roller 174a of the cam block 172 is continuously pushed up and down by the top step 168a and the bottom step 168b of the inclined guide surface 166. A linear reciprocating motion is performed while continuously moving between the upper side and the lower side of the inclined guide surface 166, and the practitioner performs a tattoo on the skin by stabbing the skin while linearly reciprocating the needle 142 using this. Skin regeneration is performed to form and regenerate micropores.

In this process, the operator can be used for a variety of purposes by varying the depth of the needle 142 to stick the skin, in this case it can be easily adjusted through the needle depth adjusting unit 200.

In this case, the user rotates the scale (not shown) displayed on the outer surface of the rotary dial 202 of the needle depth adjuster 200 with respect to the outer reference point (not shown) of the casing 110 to rotate the needle by a predetermined length. 142 can easily adjust the protruding length.

If the user wants to treat the skin at a shallow depth L1 by adjusting the protrusion depth of the needle 142 protruding from the bottom of the guider 150 to be small, as shown in FIG. Rotate to the scale of depth L1.

As the rotary dial 202 rotates as described above, the plurality of two-part circular members 210a and 210b coupled to the inner circumferential surface thereof rotate to push the slider 220 and the guider 150 toward the front of the casing 110. Let's do it. In this case, a spline protrusion 240a is formed in the middle of the holder 144 fixed to the upper end of the needle 142, and the spline protrusion 240a slides in the spline groove 240b formed inside the upper end of the guider 150. Since it is coupled so as to be possible, the slider 220 and the guider 150 move linearly with the rotation of the rotary dial 202 to move forward of the casing 110.

As the guider 150 moves forward as described above, the guider 142 positioned inside the guider 150 has the guider 144 of the upper side thereof fixedly coupled to the connecting rod 186 so that the guider 150 is fixed. When the bottom protruding depth of the 150 is adjusted forward with respect to the casing 110, the length of the needle 142 penetrating the bottom of the guider 150 and protruding downward is reduced, resulting in the needle 142 being skinned. It is to control the depth of the stab shallowly.

On the contrary, if the depth of the needle 142 protruding from the lower end of the guider 150 is to be applied to the skin at a deep depth L2, as shown in FIG. 6B, the rotary dial 202 is defined to have a predetermined depth. Rotate in the opposite direction with the scale of (L2).

Through this operation, the lower guider 150 is moved to the inside of the casing 110, and the length of the needle 142 protruding therefrom is increased to deeply control the depth at which the needle 142 pierces the skin. As described above, since only the direction thereof is reversed, a detailed description thereof will be omitted.

As described above, the complex apparatus 100 for skin according to the present invention is connected to the driving motor 124 to rotate the cylindrical cam 162 and the rotation operation of the cam 162 to the linear movement movement in the axial direction therein. Since the needle 142 is moved forward and backward through the power converter 160 having the cam block 172, a separate spring for needle reverse is not required and the left and right vibration of the needle 142 is not generated. The straightness of the needle 142 can be greatly improved.

Therefore, the present invention prevents skin damage during tattooing or skin regeneration, minimizes pain, and enables high quality skin treatment.

In addition, according to the present invention, the connection point formed at the front end of the casing 110 and the top of the guider 150 of the needle mounting part 140 further includes a needle depth adjusting part 200 at the lower side of the casing 110. The lower protrusion depth of the guider 150 for guiding the needle 142 can be easily adjusted back and forth with respect to the casing 110.

Therefore, the present invention can easily adjust the depth of the needle 142 protrudes from the bottom of the guider 150 by simply rotating the rotary dial 202 of the needle depth adjustment unit 200, stab the skin, tattoo surgery or skin regeneration It can be conveniently used for the purpose of the procedure.

Although the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited to such a specific structure. Those skilled in the art will be able to variously modify or change the embodiments of the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. Nevertheless, it will be apparent that all such modifications or design modifications to such simple embodiments will clearly fall within the scope of the present invention.
