FIG. 1 is an exploded perspective view of a needle assembly for a skin treatment apparatus according to an embodiment of the present invention, FIG. 4 is an exploded perspective view of a needle assembly for a skin treatment apparatus according to an embodiment of the present invention, FIG. FIGS. 5A to 5C are views illustrating an operation of a needle assembly for a skin treatment apparatus according to an embodiment of the present invention; FIGS.

A needle assembly for a skin treatment device according to an embodiment of the present invention is coupled to a syringe C mounted on a gun and inserted into the skin and injected with a drug of the syringe through a plurality of needles N. [

The needle 2 is formed in a handgun shape and has a syringe holder 22 to which a syringe C filled with a drug solution is removably seated and fixed. And a piston retention portion 27 is formed at the rear upper portion so that the piston of the syringe C is detachably held so as to be movable back and forth. A handle 25 for facilitating gripping is formed.

A trigger 26 is formed on the knob 25 so that the chemical liquid injection can be manually turned on and off.

The needle N of the needle assembly A is inserted into the skin by pulling the trigger 26, so that the chemical solution can be injected.

The driving unit 24 includes a motor 241 and a screw 242 connected to the motor 241 and includes a connecting rod 243 connected to and moved to the screw 242. A connecting rod 243 is connected to the syringe barrel 22).

Therefore, the syringe bar 22 is operated back and forth by the operation of the driving part 24. [

On the other hand, the piston operating portion 28 is provided so as to operate the piston wave spring 27 forward and backward.

The piston operating portion 28 is constituted by a motor 281 and a screw 282 connected to the shaft of the motor 281 and the piston 28 is coupled to the screw 282 to be operated forward and backward.

Hereinafter, a needle assembly A according to an embodiment of the present invention will be described.

The needle assembly A includes a housing 3, a body 4 coupled to the housing 3, a holder 6 coupled to the body 4 and inserted into the housing 3 and equipped with a needle N And a depth adjusting means 8 formed on the housing 3 to adjust the forward and backward lengths of the body 4.

A plurality of first needle holes 32 are formed in a front portion of the housing 3, an opening 33 is formed in a rear end of the housing 3, and a fastener 34 is formed on one side of the housing 3 .

The fixture 34 is mounted and fixed on the needle mounting base 23 of the key 2.

The body 4 is inserted and coupled through the rear end opening 33 of the housing 3 and has a plurality of through holes 41 corresponding to the first needle holes 32 formed in the front portion thereof. In a state in which it is inserted in the front side.

The holder 6 is coupled to the inside of the rear of the body 4 and has a plurality of needles N formed at the front and an injection port 63 communicating with the syringe C at the rear.

The depth adjusting means 8 is coupled to a dial knob 82 formed on one side of the housing 3 and the body 4 is operated forward and backward by the cam movement of the dial knob 82, The depth of injection of the needle of the needle can be adjusted.

A shaft rod 81 is formed at one side of the housing 3 to which a dial knob 82 is coupled and includes a display unit 84 formed radially corresponding to the outer circumferential surface of the dial knob 82.

The display portion 84 includes a protrusion 842 protruding in an arc shape and a numeral 843 formed at an upper surface of the trough 842 at regular intervals to indicate a numerical value to which the needle N is to be exposed.

Of course, in addition to the number 843, other forms of display means, such as color or braille, may be used.

A cutout hole 35 is formed at one side of the housing 3 and is formed to be cut from the rear end opening and formed to correspond to the body 4.

The dial knob 82 is formed in a circular plate shape, and a semicircular guide groove 821 is formed on one side and a latching piece 822 having elasticity is formed on the other side.

The latching piece 822 may be resilient by forming an arc-shaped cutting hole 823 on the upper side of the dial knob 82 and the outer surface of the latching piece 822 is convexly formed.

A plurality of engaging grooves 845 are formed at predetermined intervals along the inner circumferential surface of the trough 842 at the trough 842 of the display portion 84 to correspond to the engaging pieces 822.

One side of the body 4 is formed with a boss 43 which is coupled to the incision hole 35 and inserted into the guide groove 821. The rotation of the dial knob 82 allows the boss 43 to be moved in the shape of an arc by the shape of the guide groove 821 and the boss 43 is engaged with the straight- The boss 43 can be moved back and forth along the incision hole 35. As shown in FIG. This is referred to as driving by a cam (CAM) method.

A specific embodiment of the length adjustment of the needle N of the cam (CAM) method is as follows.

For example, the adjustment amount of the length of the needle (N) is 0.1 mm. This is a value corresponding to the engaging groove 845 formed on the inner peripheral surface of the lower jaw 842.

The total length of the needle N can be adjusted to 0.5 mm to 1.5 mm and the dial knob 82 is rotated to adjust the length of the needle N by 0.1 mm.

At this time, it is difficult to confirm the effect of the effect when the control section is 0.5 mm or less. When the control section is 1.5 mm or more, the uniformity of the quality and the size of the means for controlling the depth of the needle assembly increase in proportion.

It also includes an auto-injection feature.

Auto Injection is a device that injects an automatic drug according to the user's setting value (1,000 msec unit) after the negative pressure recognizes the pressure rise for the user's convenience.

The security of the user setting value Negative pressure intensity is set to +3 above the setting value, and when the auto injection function is implemented, it can be changed to the setting value, and the drug delivery efficiency can be improved.

The operation of the needle assembly for a skin care device of the present invention constructed as above is as follows.

The length of the needle N to be drawn out, the amount of the injected chemical liquid, and the intensity of the current are set in advance by operating the control unit (not shown).

Thereafter, the dial knob 82 of the needle assembly A is rotated to an appropriate value.

As an example, the needle assembly of the present invention can be configured to be exposed to a length of the first 0.5 mm. In this case, since the dial knob 82 is rotated and adjusted by 0.1 mm per latching groove 845, 11 stages can be adjusted, and the length of the needle N can be adjusted within a range of 0.5 mm to 1.5 mm in the control section . The above figures can be changed to various values as an example.

Thereafter, when the front end of the needle assembly A is brought into close contact with the skin and waiting for 1 to 2 seconds, the drug is automatically injected by the auto-injection function.

That is, the syringe holder 22 and the syringe 4 advance simultaneously and the body 4 of the needle assembly A, the holder 6 and the needle N advance simultaneously, Is drawn out from the housing 62 to a predetermined length.

The drawn needle (N) is inserted into the skin. The inserted length is the above-described set length.

Thereafter, the chemical solution of the injector 4 is injected into the skin by a predetermined amount through the needle N while the piston waveguide 27 is advanced.

Here, current may be applied to the needle N after injection of the drug.

By stimulating and activating the cell tissue by applying a high frequency current to the needle N, the drug remaining in the skin can be absorbed into the cell tissue.

In addition, suction is performed by operating the suction device together with the injection of the drug.

The needle 4 and the holder 6 and the needle N of the needle assembly A are simultaneously retracted at the same time The needle N is released from the skin and returned.

While the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
