Hereinafter, with reference to Figures 1 to 4 for explaining an embodiment of the present invention will be described in detail.

1 is a view illustrating a seal inserter to which a coupling structure of a coil spring PDO and a needle tube 100 is applied according to an embodiment of the present invention.

FIG. 2 is a view illustrating a coupling structure of the coil spring PDO and the needle tube 100 illustrated in FIG. 1.

3 is a perspective view and an enlarged view in which the auxiliary part 320 is additionally configured in the drawing of FIG. 1.

4 is a flowchart illustrating a coupling method of the coil spring PDO and the needle tube 100 according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the seal inserter to which the coupling structure of the coil spring PDO and the needle tube 100 is applied according to an embodiment of the present invention may include a needle tube 100, a needle needle 200, and a needle guide 300.

Specifically, the acupuncture tube 100 is suture (T) is connected and inserted into the skin so that the suture (T) can be seated on the skin.

In this case, the suture T may be an absorbent suture T inserted into the body and formed of polydioxanone (PDO) and having a property of being absorbed into the body.

One end of the suture T may be inserted into the needle tube 100, coiled spirally along the outer circumferential surface of the needle tube 100, and knotted once or twice to be fixed outside the needle tube 100.

In addition, after one end of the suture (T) of the present invention is inserted into the acupuncture tube 100, so as to protrude 1 to 1.5cm to the rear side of the acupuncture 200, when the position fixing of the suture after the procedure is not seated, protruding suture Hold (T) and pull it out so that it can be settled exactly where you want.

That is, as formed as described above, the elasticity around the suture T increases, so that the skin is relaxed and inserted smoothly.

In addition, if the suture (T) is not protruded to the rear side of the acupuncture 200, the end of the suture (T) may be exposed to the outside of the skin of the treated area, the blood is invaded during the suture (T) removal process, the external bacteria There is a fear of infection.

Therefore, the suture (T) inserted in the process of pulling the protruding suture (T) serves to help maintain or fix the coiled state in a spiral as it is, needle guide 300 and auxiliary after insertion of the needle tube (100) It was designed to pull after pulling out the acupuncture (310) (100).

In addition, the suture (T) in the process of removing the suture (T) can be cut by pulling the amount to be fixed so as not to protrude out of the skin can be prevented infection by external bacteria due to invasion of blood.

In other words, if the protruding to less than 1cm to the rear side of the acupuncture 200, it is difficult to get the same effect as the picking up by hand, when protruding more than 1.5cm, interferes during the procedure is more likely to be exposed to external bacteria There is a most preferably protruding from 1 to 1.5cm to the rear side of the immersion 200.

1 is a universal catheter cannula L type, which is shown by way of example, the acupuncture tube 100 is a needle and general purpose catheter cannula (C Type, L Type, N Type, W) are generally used Type, LS Type, etc.) can be used depending on the procedure and purpose of use.

Acupuncture 200 may be connected to the rear end of the acupuncture tube 100 to serve as a handle.

Accordingly, the thread inserter may be easy to be gripped by the user during the procedure, and the gland tube 100 may be easily inserted into the skin by preventing slipping during gripping.

The needle guide 300 is fixed to the front of the needle 200, and may include an auxiliary needle tube 310.

At this time, the needle guide 300 may be formed to be moved forward or backward along the longitudinal direction of the needle tube (100).

In other words, when the needle guide 300 is not used unlike the prior art, the needle guide 300 is fixed to the needle 200 and protects the coiled suture T, and when the user presses, the needle guide 300 moves to pressurize the rear side of the suture T It can be easily inserted into the skin.

Therefore, unlike the prior art, the suture (T) is often pressurized only when the procedure is not stimulated, so there is no fear that the suture (T) will be damaged.

The auxiliary needle tube 310 may be formed larger than the diameter (or outer diameter) of the needle tube 100 and may be formed of a stainless steel tube.

At this time, after punching the end of the auxiliary needle tube 310 and lumped together, the sharp part remaining on the end may be smoothly processed to be blunt.

That is, when the suture (T) is pushed to rest in the skin, the suture (T) may be broken if the end of the auxiliary acupuncture tube (310) is cut only in the cut state, which is rather disturbing during the procedure. It is desirable to process the ends smoothly and bluntly.

When the acupuncture tube 310 and the suture T are inserted into the skin, the auxiliary acupuncture 310 may be inserted into the skin so that the coiled suture T is not deformed, thereby securing a space to be positioned in the skin. have.

Accordingly, the knot portion of the suture (T) is seated in the correct position in the skin to give a lifting effect.

That is, when the acupuncture tube 100 is removed from the skin, the auxiliary needle tube 310 holds the position of the end of the suture T to prevent the suture T from being pushed backward along the longitudinal direction of the acupuncture tube 100. can do.

In addition, it may further include a protective cover 400 for protecting the blade tip and the suture (T) of the needle tube (100).

Although not shown in the drawing, it is formed in a cylindrical shape with a space therein, one end may be an open form.

At this time, since the protective cover 400 is configured to protect the needle tube 100 and the suture (T), it is formed in a length that can be fitted from the needle tube 100 to the tip of the needle guide 300, and unlike the prior art when acupuncture It can be coupled to the tip of the needle guide 300 that is fixed in the interference fit method (200), the suture (T) can be protected without being damaged by loosening can be precisely position adjustment during the procedure.

In addition, referring to Figure 3, when the suture (T) is pressed on the skin, it may further include an auxiliary portion 320 provided in front of the auxiliary needle tube 310 to insert a little more stable.

The auxiliary part 320 may include a moving plate 321, a moving tube 322, and a fixing bar 323.

Specifically, the moving plate 321 is formed in the shape of a circular plate having a larger diameter than the auxiliary needle tube 310 in the drawing, but is not limited thereto, and the auxiliary needle tube 310 and the suture T are larger than the coiled diameter. Once formed is enough.

That is, it may be made of a circle, a square, a triangle, a pentagonal (polygonal) plate.

In addition, the moving plate 321 may be moved along the needle tube 100 by passing through the same center as the hollow diameter of the auxiliary needle tube 310.

The moving tube 322 may be coupled to the front of the auxiliary needle tube 310 in a configuration connected to the penetrated portion.

In addition, the length of the moving tube 322 is not limited, and may vary according to the length of the needle tube 100 and the coiled length of the suture T coupled to the needle tube 100.

In addition, the moving tube 322 is coupled to the auxiliary needle tube 310 is a hook method can be convenient to combine / separate.

That is, the needle guide 300 may be pressurized when the suture (T) is seated on the skin, but during the procedure requiring fine movement, the moving tube 322 is separated from the auxiliary needle tube 310 to move the plate ( 321 may be moved to pressurize.

The fixing bar 323 is provided in plurality in front of the moving plate 321, it may be formed in a cylindrical shape in the drawing.

However, this shape is not limited thereto, and is provided to prevent the shape of the coiled suture T from being deformed and to prevent the coiled suture T from being deformed.

In addition, the fixed bar 323 is formed on the moving plate 321 to be spaced apart at a predetermined interval from the outside of the coiled suture (T) in the drawing, which is shown to easily explain the shape and structure of the fixed bar 323 It is merely to the original can be formed to be in close contact with the outer surface of the suture (T) as much as possible.

That is, because the shape of the coiled suture (T) must be in close contact without being deformed and pressed into the skin.

In addition, the coiled portion can be prevented from loosening by that much.

Next, referring to Figure 4, the coupling method of the coil spring PDO and the needle tube 100 according to an embodiment of the present invention step of inserting one end of the suture (T) into the groove of the needle tube 100 (S10), suture Spirally coiling the other end of the (T) to the outside of the needle tube (100) (S20), the step of closely contacting the coiled suture (T) so that there is no gap (S30), the suture (T) is the needle tube (100) It may comprise the step of knotting to be fixed to (S40).

Specifically, the step S10 and S20 is a step of coiling the suture (T) described above, by inserting one end of the suture (T) into the groove of the acupuncture tube (100), the other end of the outside of the acupuncture tube (100) By spirally coiling in the suture (T) may be provided to give an elastic force when seated in the skin.

In addition, in step S10 the suture (T) is inserted into the groove of the needle tube 100 to protrude 1 to 1.5cm toward the rear side of the needle 200.

That is, to ensure that the suture (T) is accurately seated in the desired position during the procedure.

At this time, in order to maximize the above effects, step S30 must be performed, and the coiled suture (T) must be closely adhered so that there is no gap to relax the skin to give a lifting effect.

Step S40 is a step of knotting the suture (T) to be fixed to the acupuncture tube 100, wherein the knot is most preferably knotted once or twice.

Knotting more than once or twice may cause the skin to bulge outwardly when seated on the skin, which is not aesthetically pleasing and may reduce the lifting effect.

In addition, the coiled suture (T) is easily deformed and difficult to be fixed to the acupuncture tube (100) unless the knot is made as in step S40.

In addition, it may be useful for the user to press and release by hand when leaving the acupuncture tube 100 from the suture (T) to secure the suture (T) in the body.

That is, it may be useful to press the needle guide 300 in the procedure to position the suture (T) in the body, and to completely detach from the acupuncture tube (100) to the rear end of the suture (T).

On the other hand, the skin treatment method using the coil spring PDO of the present invention comprises the steps of marking on the skin one or more lifting treatment site of the off cheeks, nasolabial folds, grumpy beam, contour, brow, forehead wrinkles, skin under the eyes; Inserting the needle tube (T) coiled with the suture (T) of the coil spring POD into the skin from the tip to the suture (T) knot site; Pressing the needle guide 300 is separated from the acupuncture 200 so that the suture (T) is seated in the skin to the auxiliary needle tube 310 coupled to the needle guide 300; Removing the acupuncture tube 100 from the skin and may include a step of hemostasis with a band-aid or skin-specific patch on the surgical site.

Here, when the suture (T) is difficult to be accurately seated on the surgical site, after pressing the auxiliary needle tube 310, a part of the tip of the auxiliary needle tube 310 is inserted into the skin to suture (T) to maintain the coiling tunnel. It may further include a step of guiding to be accurately seated on the treatment site.

In addition, after the needle guide 300 is separated from the needle bed 200 and used, the needle guide 300 may further include a step of fixing the needle guide 300 at the tip of the needle bed 200 so that there is no inconvenience during the subsequent steps. .

Coupling structure of the coil spring PDO and the needle tube 100 of the present invention described above is coupled to the groove of the 'L' shaped needle tube 100 to the outside of the coil spring suture (T) formed of a polydioxanone without visible Coiling without gaps to increase the elasticity around the coiling suture (T) to the structure that is combined with the acupuncture tube 100 so that the skin is strongly relaxed, manufacturing efficiency and the reliability of the bonding can be improved.

In addition, the insertion of a single acupuncture 100 into the skin can give a strong skin relaxation, thereby preventing a wound due to the procedure.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art may implement the present invention in other specific forms without changing the technical spirit or essential features of the present invention. You will understand that. Accordingly, the embodiments described above are exemplary in all respects and not restrictive.
