Needle assembly for face lifting

Various embodiments of the present invention relate to a needle assembly for face lifting.

In recent years, in line with a trend of increasing interest in beauty, various procedures for removing wrinkles on the face or neck have emerged.

Wrinkle removal procedures include facial elevation, filler insertion, botulinum toxin injection, or laser skin regeneration, but recently, a facial surgeon removes wrinkles by inserting a special surgeon into the skin layer without cutting the plastic part A lifting method has been developed and used.

Facial lifting is a procedure that inserts a thread with a small bump, such as a rose thorn, into the skin and pulls out the wrinkles. Threads used for face lifting generally use medical threads that are harmless to the human body. Face lifting implants these threads under the skin, pulling the soft tissue evenly, pulling out loose skin and tightening the loose skin. In addition to improving wrinkles, facial lifting can catch sagging skin and sagging jaw lines, thereby eliminating wrinkles such as forehead wrinkles and nasolabial folds.

In particular, face lifting is a simple partial anesthesia that does not overwhelm the body and is performed using only special threads and needles, so that the burden on the patient can be reduced and immediate face lifting, wrinkle removal, and jawline improvement can be expected.

However, such a conventional face lifting is often the case that the end of the thread is not anchored to the skin after the insertion of the thread into the skin or the face or skin lifting is not properly performed due to the weak anchoring, so that a large number of facial faces There was a problem that should be inserted into.

1A, 1B and 1C are cross-sectional views illustrating a needle assembly 100 for face lifting according to various embodiments of the present disclosure, and side and partial enlarged cross-sectional views of the lifting seal 130.

1A to 1C, the needle assembly 100 for face lifting according to an embodiment of the present invention may include a needle 110 and a lifting seal 130.

Needle 110 may be coupled to a syringe (not shown). The needle 110 may be coupled to the plastic connector 120 substantially, and the plastic connector 120 may be coupled to the end of the syringe. The needle 110 and the plastic connector 120 are hollow, that is, hollow, so that the lifting chamber 130 or the drug can pass therethrough. Of course, the needle 110 may be made of metal or plastic, for example, but not limited to.

In addition, the needle 110 may further include a chamfer 111 whose outer diameter gradually decreases at an end adjacent to the anchor 133 of the lifting seal 130 to be described later. That is, the chamfer 111 may be formed by grinding the end of the needle 110 so that the outer diameter gradually decreases toward the end of the needle 110. Skin damage is minimized when the needle 110 is inserted into the skin by the chamfer 111. If the chamfer 111 is not processed, burrs may remain at the ends of the needles 110, which may cause damage to the skin during the procedure.

The lifting seal 130 may include a body 131 having a predetermined length, a plurality of protrusions 132 formed on the body 131, and an anchor 133 formed at an end of the body 131. Here, the plurality of protrusions 132 are formed at a predetermined pitch along the longitudinal direction of the body 131, and serves to anchor the body 131 so that the body 131 does not move when the body 131 is inserted into the skin. In addition, the anchor 133 is formed so that the end is approximately round and pointed, not only to facilitate insertion into the skin, but also strongly anchored to the skin after the insertion is completed to maintain the lifting seal 130 to maintain the procedure position.

Here, the body 131 of the lifting seal 130 is located inside the needle 110, the anchor 133 is located outside the needle 110. Accordingly, the anchor 133 located at the end of the needle 110 passes through the skin. In addition, the diameter (outer diameter) of the anchor 133 may be equal to or larger than the diameter (outer diameter) of the needle 110. Preferably, the diameter (outer diameter) of the anchor 133 may be larger than the diameter (outer diameter) of the needle 110. Therefore, the anchor 133 does not enter the needle 110 when the needle 110 is inserted into the skin, so that the procedure can be performed successfully. Of course, the diameter (outer diameter) of the anchor 133 is larger than the diameter (outer diameter) of the body 131, so that it is anchored firmly in the skin after the procedure.

In particular, the anchor 133 is, for example, but not limited to, the flat portion 134 in contact with the end of the needle 110 and the outer diameter from the flat portion 134 as shown in FIG. 1C. It may include a small and extended inclined portion 135, and a round portion 136 for closing the end of the inclined portion 135. Here, the outer diameter of the boundary area between the flat portion 134 and the inclined portion 135 may be equal to or larger than the outer diameter of the needle 110.

Therefore, when the lifting seal 130 composed of the body 131 and the anchor 133 having a plurality of protrusions 132 is inserted into the skin, the procedure position is maintained until it naturally melts away.

On the other hand, the lifting seal 130 may be made of PDO (Polydioxanone) having biodegradability and excellent in a strong retention period. Since the PDO component promotes collagen remodeling, the lifting sustaining force is maintained even after the lifting seal 130 melts away.

In addition, the lifting seal 130 is a single yarn such as polypropylene, polyacrylonitrile, monocarryl, polycarprolactone (PCL), poly (glycolic acid), and polylactic-co-glycolic acid (PLGA). It may be made of biodegradable polymer (MonofilmentBIODEGRADABLE POLYMER).

In addition, it is obvious that various features of the above-described embodiments may be applied to all other embodiments described herein.

2A to 2D are cross-sectional views illustrating a cross section of a needle among the needle assembly 100 for face lifting according to various embodiments of the present disclosure.

As shown in FIGS. 2A-2D, the cross section of the needle is, for example, but not limited to, circular 110A, elliptical 110B, pentagonal (or ∞ shaped) 110C or rectangular 110D. Can be. Thus, for example, but not by way of limitation, when the shape of the needle is elliptical 110B, pentagonal (or ∞) 110C or rectangular 110D, at least two lifting seals 130 are accommodated. Allow the procedure to proceed. Therefore, the two lifting seals 130 can be positioned in the skin in one operation, thereby reducing the number of procedures.

As shown in FIG. 3, the anchor 233 of the lifting seal 230 may include a second flat portion 234 having an expanded diameter between the inclined portion 135 and the rounded portion 136 compared to the inclined portion 135. And, the outer diameter from the second flat portion 234 to the round portion 136 is gradually reduced and may further include a second inclined portion 235 extended. That is, the anchor 233 of the lifting seal 230 has two

flat portions
