BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for injecting a suture into a skin, and a method of injecting a suture using the suture, and more particularly, to an injection apparatus and an injection method including a groove in which a suture is seated.

Among the various procedures for removing the wrinkles existing on the skin surface of the human body in recent years, as a thread for medical use, a practically used suture obtained permission for the use of the human body is inserted into the subcutaneous tissue and the subcutaneous tissue and the dermal tissue are adhered to each other There is a way to use the principle that the tension is strengthened. Further, when the above-mentioned cohesive portions are pulled and fixed to the upper side, the principle that the stretched portions are raised and fixed by the tension of the suture is used.

Such a procedure, so-called lifting, involves pulling together aged skin and aging soft tissue (SMAS) in the skin to remove wrinkles and resurrect the elasticity, and by using the needle through simple local anesthesia, The incidence of scarring, which is the greatest disadvantage of such methods as incision of the skin of the user, for example, facial elevation, can be minimized. In addition, it has the advantages of less bleeding and swelling caused by it, as well as reduced irritation and damage of the treatment area, and it has been widely practiced since it gives natural tension to the skin to make the skin appear elastic and youthful.

As the lifting procedure becomes more common, the suture used in the treatment has also been evolved. Specifically, the suture used for the treatment has been strengthened by processing the suture such as a cog or a leaf to have a protrusion, There is a case in which an effect of being fixed to the tissue only in one direction is provided. In addition, various attempts have been made to enhance adhesion, such as different orientation.

However, the conventional thread having a simple connection of the engaging projections is effective at the beginning of the procedure, but this has also been disadvantageous in that the lifting effect is significantly reduced as time passes (within about 6 months) naturally slips.

Therefore, it is necessary to use thick sutures to increase the friction between the subcutaneous muscles and the suture for effective treatment. For example, retinas made of a three-dimensional net structure twisted with dozens of thin threads are now selective for deep wrinkles or severely intense skin .

US Patent Application Publication No. US 2011-0112557 "Apparatus and method for laparoscopic port site suture"

A conventional syringe-like injector for injecting a suture is a method of pushing a suture inserted into a needle into the skin (see Fig. 1). In the background art described above, the retinas used for maximizing the lifting effect The use of such an injector to inject a thick suture such as a suture into the skin limits the thickness of the suture that can be selected since only a suture thinner than the needle inner diameter of the injector can be inserted into the needle. On the other hand, expanding the inner diameter of the needle for the use of coarse sutures may not be a suitable solution because it may cause pain of the recipient and scarring of the penetrating skin.

As an alternative to injecting thick sutures, a hook-shaped needle is a method of pulling a suture released from a suture injection port to a hook-shaped hook by pulling a suture discharged from a suture outlet, and the skin penetration portion has two points, There is a problem.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a suture infusion device including a head, a main body, and a handle, wherein the head includes a tip portion penetrating the skin, The suture injection device according to claim 1, In the suture injection device of the present invention, the suture is bent in the form of '⊂' so that the suture is injected into the subcutaneous muscles in a double state.

The head portion of the suture injection device of the present invention means from the uppermost end of the tip portion to the innermost end of the groove portion, and the entirety of the head portion is inserted into the skin as a portion penetrating the skin and seating the suture. In this case, the length (ℓ) of the head part is preferably 1.5 ≦ ℓ ≦ 40 mm, and the minimum diameter (D _home-min ) of the groove part is the maximum diameter of the body part (D _body-max ) Is preferably within 10 to 90%.

When the injection device and the injection method including the groove portion in which the suture thread of the present invention is seated is applied, there is no limitation in the thickness of the suture thread, and a coarse suture thread like a retent can be injected conveniently and stably, Since the double suture is injected into the subcutaneous muscles, the friction between the subcutaneous muscles and the suture is increased and the lifting effect is improved.

In addition, in the case of using a conventional hook-shaped needle, the skin penetrates through two places. However, the suture injection device of the present invention injects only one site to seat the suture and recover from the injection port, thereby minimizing skin damage and scarring. , Shortening the recovery period and minimizing side effects.

FIG. 1 is a cross-sectional view of a needle of an injector for injecting a conventional suture using a principle in which a suture is injected into a needle, which is a needle. When such a conventional injector is used, only a suture thinner than the inner diameter of the needle can be used. As in the known lifting procedure, the suture is pushed to the side while pushing the wrinkled or unstressed skin with the finger of the operator, and at the same time, the suture inserts the needle into the suture with the needle and the subcutaneous muscle is injected. In this state, when the operator pushes the upper skin of the inserted needle and pulls the needle, only the suture remains on the skin, and the skin with wrinkles or decreased elasticity is pulled to the side and lifted. The suture out of the skin is cut and finished.

2, the suture injection device according to the present invention includes a head portion 10, a main body portion 20, and a handle portion 30. The suture injection device includes a head portion 10, (11) and a groove (12) in which the suture is seated in the form of '⊂'. In the suture injection device of the present invention, the suture is bent in the form of '⊂', and is injected in the state of hanging in the groove portion 12, so that there is no limitation in the thickness of the suture and the double suture is injected into the subcutaneous muscle do.

2, the head portion 10 of the suture inserting device of the present invention means from the uppermost end of the tip portion 11 to the innermost end of the groove portion 12, The whole of the head portion 10 is inserted into the skin.

On the other hand, the handle 30 refers to the rest of the head except the head 10 and the main body 20, and is a portion that the practitioner grasps and pushes or pulls by hand. As shown in FIGS. 2 to 4, the suture injection device according to an embodiment of the present invention clearly distinguishes the boundaries between the main body portion 20 and the handle portion 30, but in some cases, .

3, the length (ℓ) of the head portion 10, which is the horizontal distance from the top end of the tip portion 11 to the innermost end of the groove portion 12, is 1.5 ≦ ℓ ≦ 40 mm is most preferred for penetrating the skin and seating the suture. The tip 11 has a length of 0.5 to 30 mm and an optimum range of 1 to 10 mm. The length of the groove 12 is 1 to 10 mm and the optimum range is 2 to 5 mm. If the length of the tip 11 is short, the skin penetration is weak. If the length of the tip 11 is long, the distance from the suture that is seated on the groove 12 becomes long, .

Although the diameter (D) of the suture injection device according to the present invention is not limited, it is possible to adjust the diameter of the suture injection device within a diameter range that can be injected into the skin according to the thickness of the suture material to be injected.
