Description

{Skin Surgical Operation Apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a skin treatment apparatus, and more particularly, to a skin treatment apparatus, and more particularly to a skin treatment apparatus for repeatedly inserting and withdrawing a needle reciprocally driven by a motor, And a skin treatment apparatus that can be used for tattoos and the like.

A tattoo device refers to a device that uses a tattoo ink and a needle to express a pattern or figure such as a symbol, letter, or figure on a person's skin.

Such a tattoo device automatically moves back and forth in order to facilitate the operation of the tattoo, and while the needle is reciprocating, the tattoo ink comes down on the needle. When the needle moves the person's skin to a certain depth The desired pattern can be expressed on the human skin according to the intention of the tattoo practitioner.

Most of such conventional tattoo devices utilize the power of the driving motor to advance the needle, but most of them use the elastic restoring force of the spring to reverse the needle.

Therefore, when such a conventional tattoo device is used for a predetermined period of time, the resilient restoring force of the spring is changed, so that the protruded needle does not retreat or takes a long time to retreat. If the needle does not reciprocate correctly, it will not be possible to accurately draw the tattoo.

In order to solve such a problem, a "tattoo device" of Patent Registration No. 10-0789398 has been proposed.

Such a conventional technique has a cam unit that has a drive motor installed inside a case such as a pen and converts the rotation of the drive motor into a linear reciprocating motion, and a needle is provided so as to move forward or backward through a link.

The cam unit includes a cam that is rotated by the driving motor and a cam follower that performs a linear reciprocating motion in accordance with the rotation of the cam, the cam being connected to the driving motor through a pair of bevel gears.

Therefore, in such a conventional tattoo device, the contact point of the cam and the cam follower is disposed so as to be aligned with the needle to secure straightness.

However, such a conventional technique causes vibration in the course of the cam and cam follower movement being transmitted through the link.

As a result, such a vibration hinders the straightness of the needle and makes it swing to the left and right. Thus, when a practitioner performs a tattooing operation, the forward trajectory of the needle and the backward trajectory are made different, and still cause skin damage and pain.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a needle dispenser which does not use a spring during advancing and retracting operations of a needle so as to stably maintain the immediacy of the needle And it is an object of the present invention to provide a skin treatment apparatus which can easily perform an operation for an accurate position in skin treatment and minimize pain.

It is an object of the present invention to provide a needle having a pen-shaped body for gripping by hand, the needle being projected and operated on one end of the body, the body including a driving motor, Wherein the power switching unit comprises: a main body having a space formed therein and the first and second semicircular members formed on one side thereof with semicircular insertion portions facing each other; A rotary plate inserted in the body, inserted in the insertion portion, coupled to the shaft of the driving motor and rotated, and eccentrically formed on one side to form a protrusion; An operating member inserted into the space of the main body and having a groove having a cross-sectional area larger than a cross-sectional area of the protruding portion to which the protruding portion of the rotating plate can be inserted but being biased to one side and having a hinge- A link hinged at one end to the hinge coupling portion of the actuating member and hinged to the hinge coupling portion of the actuating member at a pin, And a shaft having a connecting portion formed at one end thereof so as to be hinged by a pin at the other end of the link, and a needle is connected to the other end of the shaft.

According to the present invention, it is possible to stably maintain the immediacy of the needle without generating a right-left vibration of the needle without using a spring in advance and backward operation of the needle, , And there is an effect that the pain can be minimized.

The body 100 is formed in a pen shape, and a wire to which power is supplied is connected to one end or a battery is mounted inside the body.

A switch 120 is formed on one side of the upper part of the body 100 and a guide member 130 connected to the power switching unit 2 and the power switching unit 2 toward the lower side, And a cap 150 at the tip.

The power switching unit 2 includes a main body 20; A rotary plate 22 inserted into the main body 20 and coupled to the shaft of the driving motor 200 and eccentrically formed at one side thereof to form a protrusion 221; A groove 242 which is inserted into the space of the main body 20 and has a cross sectional area larger than a cross sectional area of the protrusion 221 although the protrusion 221 of the rotary plate 22 can be inserted is formed in one side, An operation member 24 on which a hinge engaging portion 244 is formed; A link 26 hinged to the hinge coupling part 244 of the actuating member 24 by a pin and rotatably coupled to the body 20 by a rotation axis in the middle; And a shaft 28 formed with a connecting portion 282 formed at one end thereof so as to be hinged by a pin at the other end of the link 26. A needle 300 is connected to the other end of the shaft 28 .

The main body 20 has a space formed therein, and the first and second semicircular elements, on which semicircular insertion portions 201 are formed, are coupled to each other.

The rotary plate 22 is in the form of a circular plate and a boss 222 for receiving the shaft 209 of the drive motor 200 is formed on one surface of the rotary plate 22. The protrusion 221 is formed on the front surface, Eccentrically.

The projecting portion 221 is formed into a cylindrical shape.

The operation member 24 is formed in a rectangular parallelepiped shape and is inserted into the space of the main body 20 and has a groove 242 having a cross sectional area larger than the cross sectional area of the projecting portion 221 into which the projecting portion 221 of the rotary plate 22 can be inserted And a hinge engaging portion 244 is formed on one surface.

Two diaphragms 243 are formed on one surface of the operation member 24 and a hinge engaging portion 244 is formed at one end of each diaphragm 243. The hinge engaging portion 244 is provided on both sides And a slot is formed between the two diaphragms 243.

One end of the link 26 can be inserted into the slot and can be closely contacted.

The link 26 is formed in an approximately "B" shape in a plan view, and an arc-shaped engaging portion 265 is formed in the hinge engaging portion 244 of the actuating member 24 so as to be hinge- A cylindrical penetrating portion 266 is formed to be rotatably coupled to the main body 20 by a rotating shaft 262 and a through hole 267 is formed at the other end.
