The present invention is an invention related to a mae line and a mae line self-inserting machine, specifically, the invention related to a film type ed line self-injection device that allows easy insertion of the film-like line and the film type into the skin to be.

The skin is divided into three layers: the outermost layer of the epidermis, the middle layer of the dermis, and the subcutaneous tissue below. Among them, most of the collagen and elastin, which determine the skin's elasticity, sagging, and wrinkle formation, are present in the dermis layer. The most effective treatment for the recovery and prevention of aging is to target the dermal layer.

On the other hand, in order to solve the problem of aging, various treatment methods such as surgery, Maeseon therapy, drug injection method, and laser treatment have been developed and used, and a representative one is Maeseon therapy.

Maeseon therapy is a procedure in which a circular standard standard bioabsorbable Maeseon is inserted into the skin layer together with an injection needle, then Maeseon remains in the skin and only the inserted injection needle is removed. It plays a role in promoting the production of collagen and elastin through continuous mechanical stimulation for many years.

However, as described above, since the dermal layer determines the production of collagen and elastin in the skin, procedures for promoting collagen production must be performed with the dermal layer as a target. However, in the case of Maeseon according to the prior art, a standardized circular shape without considering the thickness of the dermal layer Because it has the shape of, in most cases, when the skin is inserted into the skin, the skin is protruded out of the skin due to its thickness and shape, or the dermal layer, the subcutaneous fat layer, and the muscle layer are all included in most cases.

Therefore, there existed a problem in that the portion of the skin that could not be inserted into the dermal layer that leads to the generation of collagen, as well as the side effects such as reflection and foreign body sensation on the skin surface, caused loss in collagen production as much as that portion.

Maeseon according to an embodiment is an invention devised to solve the above-described problem, and a model of Maeseon is manufactured in the form of a flat film considering the thickness of the dermal layer. When Maeseon is inserted into the dermal layer of the skin, a part of Maeseon is external to the skin. Its purpose is to prevent it from protruding or being inserted into the subcutaneous fat.

In addition, the self-introduction device according to an embodiment is a self-introduction device manufactured so that each line can be effectively inserted into the dermal layer, and by making a model of the self-introduction machine according to each line in the form of a film, each line is not inserted into another layer, but Its purpose is to ensure that all are inserted into the dermal layer.

Each line in the form of a film according to an embodiment is a line that is formed long in one direction, wherein the shape of each line is in the shape of a flat film, and the horizontal length of each line is 5 times or more than the height of the line. It can be characterized.

1 is a view showing a comparison of the appearance of each line 1 according to the prior art and each line 10 in the form of a film according to an embodiment.

Referring to FIG. 1, each line 10 in the form of a film according to an embodiment has a structure that is elongated in one direction, and the shape of each line 10 in the form of a film has a shape of a flat film.

The skin is divided into three layers: the outermost layer of the epidermis, the middle layer of the dermis, and the subcutaneous tissue below it. Among them, about 90% of collagen and elastin, which determine the skin's elasticity, sagging, and wrinkle formation, are fibroblasts in the dermal layer. Is formed from Therefore, it is preferable that the treatment for recovery of skin elasticity and prevention of aging proceeds to the target of the dermal layer.

However, in the case of performing the procedure using the conventional technique, as shown in Fig. 1 (a), the treatment is performed using a uniformly manufactured circular model without considering the thickness of the dermal layer. As it turned out, there was a problem that Maeseon could not be effectively inserted into the dermal layer.

That is, in the case of the face, the thickness of the epidermal layer is about 0.1 to 0.2 mm, and although the thickness of the dermal layer is generally 0.5 mm to 1.2 mm, in the case of conventional Maeseon, the diameter (r) is a circular model with a diameter of 1.0 mm to 1.49 mm. As it turns out, the diameter of each line is larger than the thickness from the surface of the skin to the dermal layer, and if the line is inserted into the dermis layer, a part of the line may protrude to the skin surface, which may interfere with daily life after the procedure. There were problems such as feeling of foreign body due to purchases and reflection of purchases.

In addition, due to this problem, in most cases, conventional bridging procedures are self-injection over the subcutaneous fat layer or the dermal layer, the subcutaneous fat, and the muscle layer below it.

However, there are blood vessels larger than the dermal layer in the subcutaneous fat layer, and if the line is inserted into the subcutaneous fat layer, side effects such as bleeding, swelling, pain, and bruising are more likely to occur.

In addition, a portion of the dermis, which leads to the production of collagen, cannot be inserted into the dermis layer, and a portion of the mashed line that is inserted across the subcutaneous fat or muscle layer acts as a loss in collagen production as much as that portion. There was a problem with the need to perform additional treatments.

Therefore, the film-shaped Mae-Seon 10 according to an embodiment is an invention designed to solve these problems, and the model of Mae-Seon 10 is not manufactured in a circular shape unlike the prior art, but in consideration of the thickness and structure of the dermal layer. The purpose is to maximize the effect of each line by reducing the loss of each line by making it into a thin film-type model, and to minimize side effects such as reflection, foreign body sensation, bleeding, swelling, and pain. .

Specifically, the horizontal length of each line 10 in the form of a film can be manufactured within the range of 0.75 mm to 1.5 mm in order to increase the surface area to act on the dermal layer and minimize pain, bleeding, and wounds to the skin fat layer. The length of 10) can be manufactured within the range of 0.15mm to 0.25mm so as to be thinner than the average thickness from the skin surface to the dermal layer.

In addition, if the ratio of the length (X) and the height (Y) of each line 10 in the form of a film within this range is 5 to 6:1, the inserted line protrudes out of the skin or the subcutaneous fat layer Because it is not inserted into the dermis, most of the dermis can be inserted into the dermis while reducing side effects and maximizing the effect.

In addition, the horizontal length (x), height (y), and length (z) of each line 10 in the form of a film according to an exemplary embodiment are of the area to be treated (face, forearm, thigh, abdomen, buttocks, etc.). It can be produced by varying the thickness and length according to the thickness of the dermal layer.

For example, the thickness of the skin dermal layer of the face is approximately 1 mm, but the thickness of the skin dermal layer of the arm is 2.13 mm on average, the thigh 1.77 mm, the abdomen 2.05 mm, and the hips 2.31 mm. Accordingly, the film-shaped wire 10 according to an exemplary embodiment may be manufactured by being deformed according to the skin thickness according to the treatment site.

In addition, the film-shaped wire 10 according to an exemplary embodiment may have various shapes within a range in which the wire in a state inserted into the skin may not be touched or reflected from the outside of the skin. For example, it can be manufactured in the form of a general smooth shape, a shape with a spinous protrusion, a shape with an embossing, a shape with a cone, a shape with a mesh, a tornado and a coil shape, etc. , Each corner can be rounded so that it does not interfere with the movement of the face.

In the case of the film-shaped Mae-Seon 10 according to an embodiment, when the film-shaped Mae-Seon 10 is inserted into the dermis layer, the effector 11 that promotes the production of collagen and inhibits decomposition and the strength of the Mae Seon is increased. It may include at least one of the biodegradable polymer materials 12 that extend the decomposition time of each line in a living body.

In order to restore skin elasticity and prevent aging damaged by aging of the skin, it is important to reduce the problem of free radicals and induce the regeneration of the connective tissue of the skin such as damaged collagen elastin hyaluronic acid.

However, if an effect agent is made with only chemical drugs for skin regeneration, there is an advantage that the chemical drug penetrates into the skin and an immediate effect can be obtained, but the effect ends as a one-time and the maintenance period is short, so the treatment must be repeated every time.

In addition, in the case of an effect agent processed in the form of a film using only chemical drugs, it is difficult to self-inject into the skin dermal layer while maintaining the shape of a film such as a thin film because the mechanical strength is weak. Even if the mechanical stimulation is insufficient, there is a problem that the collagen regeneration effect is lowered.

Therefore, the film-shaped medium line 10 according to an embodiment is a chemical drug capable of preventing aging, and at the same time, it is biodegradable to increase the mechanical strength of the benefit agent and extend the decomposition time in vivo. A method of probing a polymer material between the benefit agents was used to implement a film-shaped wire 10.

That is, the film-shaped medium line 10 according to an embodiment includes the benefit agent 11 capable of generating such a chemical effect, specifically, phyto-placenta, selenium, and glutathione ( glutathione), idebenone, copper-tripeptide-1, polydeoxyribonucleotide sodium, beta-glucan, hyaluronic acid, alpha lipoic acid It may contain at least one of (alpha-lipoic acid) and multi growth factor (MGF).

However, these constituents are only an example, and constituents included in the benefit agent 11 are not limited thereto, and various ingredients may be additionally included in the benefit agent 11 according to the purpose.

For example, cells, proteins, nucleic acids, peptides, polysaccharides, lipids, botox, vitamin C or derivatives thereof, retinol or retinol derivatives, arbutin, adenosine, caffeine, diosmethine, mayslignan, asiaticoside, polydatin, ginseno At least one of side, frangenidine, and hydroxyproline may be further included.

In addition, the film-shaped bare wire 10 according to an embodiment increases the strength of the film-like bare wire 10 and at the same time, when the film-shaped bare wire 10 is inserted into the dermal layer, it is not easily decomposed in the dermal layer and is maintained for a long time. It may include a biodegradable polymer material 12 to be able to be.

For example, polylactide, polyglycolide, polylactide-co-glycolide, polyanhydride, polyorthoester, polyetheramide, polycarprolactone, It may contain at least one of polyesteramide, polybutyric acid, polyvaleric acid, polyurethane, and polydioxanone.

However, polylactide and polyglycoic acid are more preferable as the biocompatible material forming the structure of the film-shaped wire 10 in terms of biocompatibility of the film-shaped wire 10 and the ease of absorption of the active ingredient.

According to an embodiment, when the film-type Maeseon 10 including the benefit agent 11 is inserted into the dermal layer, the film-shaped Maeseon 10 is decomposed by moisture and enzymes in the body in the dermal layer. Since silver alcohol has a terminal group, it can play a role in promoting collagen production. In addition, since the biodegradable polymer material 12 has an absorption time in a living body of about 6 to 36 months, there is an effect that can have a significantly higher in vivo retention period than when using only the film benefit agent alone.

Of course, the biodegradable polymer material 12 applied to the present invention is not limited to the components listed above, and various components may be additionally included depending on the purpose.

In addition, according to an embodiment, in the case of the film-type Maeseon 10 including a benefit agent and a biodegradable polymer, it may be manufactured in various ways, for example, wet spinning, dry spinning, It can be manufactured using melt spinning, electro spinning, or other spinning methods.

2 and 3 are diagrams showing a process in which the film-shaped medium wire 10 manufactured according to an embodiment is inserted into the dermal layer.

In the case of inserting the film-shaped Mae-Seon 10 manufactured according to an embodiment into the skin, as shown in FIG. 2, the needle body 120 of the film-shaped Mae-Seon Zhejiang machine 100 is placed in a dermal layer perpendicular to the skin layer. After inserting up to the mark line 122, the film-shaped self-contained device 100 is rotated 90 degrees as shown in FIG. 3 and placed parallel to the skin surface, and then one side of the needle body 120 is inserted. The needle body 120 is inserted all the way into the dermal layer of the skin. In this state, while holding down the surface of the skin at the position where the Mae-seon 10 is inserted, and the Mae-seon-inspired device 100 is removed from the skin layer, only Mae-seon 10 remains in the skin layer.

In the case of performing the procedure in this way, since each line is inserted parallel to the dermal layer, the line is not inserted outside the skin or toward the subcutaneous fat under the dermal layer, and the thickness of the line 10 according to an embodiment does not exceed the thickness of the dermal layer. Therefore, in the end, all of each line will exist in the dermal layer.

Therefore, when the treatment is performed using the film-shaped ties 10 according to an embodiment, unlike the prior art, loss of ties does not occur. There is an advantage in that it not only can reduce bleeding, but also side effects such as bleeding, swelling, pain, and bruising.

FIG. 5 is a perspective view showing the appearance of the film-type sheeting machine 100 according to an embodiment, and FIG. 6 is a side view showing the appearance of the film-type sheeting machine 100 according to an embodiment.

Specifically, referring to Figs. 5 and 6, a film-shaped stylus 100 according to an embodiment is coupled to one side of the stylus body 110 and the stylus body 110, so as to form a sheet into the skin ( 10) It may include a needle body 120 and a needle insertion handle 130 for inserting.

Specifically, the needle body 110 may have a rectangular shape with a flat bottom, and the needle body 120 is coupled to one side of the needle body 110 to have a flat film shape. 130 may be coupled to the upper portion of the needle body 110 in a direction parallel to the upper surface of the body body 110.

In the case of a procedure using Mae-seon, Mae-seon must be inserted parallel to the dermal layer so that Mae-seon can effectively stay inside the dermal layer. Therefore, as shown in Fig. 6, when the bottom surface of the inserter main body 110 has a flat rectangular model and the handle is coupled in a parallel direction to the inserter main body 110, Figs. 3 and 4 As shown in Fig. 9, after rotating the magnetic stripe by 90 degrees, since the movement of the magnetic stripe in the horizontal direction is possible, there is an effect of allowing the piercing to be inserted parallel to the dermal layer.

In addition, the purpose of the film-type self-contained machine 100 according to an embodiment is to allow the film-type median line 10 manufactured according to the previously described embodiment to be easily inserted into the skin. The shape of the needle body 120 for inserting the film-shaped wire 10 into the skin may have a flat film shape similar to the model of the film-shaped wire 10. Specifically, the horizontal length of the needle body 120 may be 5 times or more than the height of the needle body 120.

In addition, the needle body 120 includes an insertion unit 121 inserted in contact with the skin, a dermal layer indicator line 122 and a needle body 120 marked with lines at regular intervals so that the degree of insertion of the needle body 120 is known. ) Is inserted into the skin and then the operator presses the skin and pulls the needle body 120 out of the skin, so that the film-shaped Maesun 10 can escape to the outside of the needle body 120 and stay inside the dermal layer. It may include an opening 123 with an open side.

The insertion part 121 of the needle body 120 is a conical shape whose diameter decreases toward the end, and may be specifically implemented in a convex curved shape.

When the insertion part 121 has such a shape, it is possible to prevent subcutaneous tissue or blood vessels from being pinched inside the end because the needle body 120 is inserted in a manner that squeezes and enters the skin tissue when the needle body 120 is inserted into the skin. Therefore, there is an effect of preventing damage to tissues or blood vessels due to the procedure.

In addition, when the needle body 120 is inserted into the skin layer, a line is displayed on the insertion part 121 of the needle body 120 at predetermined intervals from the end so that the degree of insertion is indicated, so that the dermal layer indicator line 122 is exist.

In order to accurately insert the film-shaped wire 10 into the dermal layer by using the film-type wire inserting machine 100, it is important to accurately determine the depth of the dermal layer and insert the wire wire 10 into the dermal layer. However, since the thickness of the dermal layer is very thin, it is difficult for the operator to measure the depth.

Accordingly, when the needle body 120 is inserted into the skin layer, the dermal layer indicator line 122 is displayed at predetermined intervals from the end in order to know the degree of insertion of the needle body 120 according to an exemplary embodiment.

Since the average depth from the skin surface to the dermis layer excluding the face to the orbit (about 0.5 mm) is about 1 mm, it is efficient to insert the needle body into the dermal layer from 0.9 mm to 1.1 mm.

Therefore, at the end of each line embroidery machine 100, mark lines are displayed at a distance of 0.9m (122a), 1.0mm (122b), and 1.1mm (122c) from the end, so that the operator sees these lines accurately, the needle body 120 ) Can be inserted into the dermal layer.

0.9m, 1.0mm, and 1.1mm displayed on the needle body 120 are only one embodiment, and the displayed point is not limited thereto, and the position of the line displayed according to the area to be treated and the distance between the mark lines are It can be transformed and displayed according to the environment.

In addition, the thread holder 100 according to an embodiment may include a seal holder 124 capable of fixing the position of the sheet 10 in the form of a film during a procedure.

The thread holder 124 is for fixing the thread exposed through the opening 123 of the needle body 120 and may be implemented in a structure that can move along the longitudinal direction of the needle body 120.

FIG. 7 is a view showing the appearance of a wire inserting machine 100 according to another embodiment, and the wire inserting machine 100 may include a plurality of needle bodies 120 described above, and a plurality of needle bodies 120 ) May be combined with the magnetic body at regular intervals (d).

In general, there is a drawback of taking a long time since the bargaining procedure requires dozens to hundreds of bargains at once. However, as shown in FIG. 7, when the needle body 120 is inserted once the needle body 120 includes a plurality of needles 120a, 120b, and 120c, the 3 film-shaped sheets 10 It can reduce the procedure time by 1/3 because it can be inserted simultaneously. Accordingly, there is an advantage of reducing the swelling and pain of the treatment site of the person undergoing treatment, as well as increasing the efficiency of the operator.

In addition, as shown in FIG. 7, since the plurality of needle bodies 120 according to the exemplary embodiment are arranged at a uniform interval d, it is possible to prevent each line procedure from being concentrated on one side, so that it is evenly distributed over the entire treatment area. You can buy yourself a purchase. Therefore, there is an advantage of being able to form a dense collagen network overall in the treatment site.

The number of needle bodies 120 coupled to the needle body 110 may be variously modified according to the treatment site, but as shown in FIG. 7, three may be combined, and in addition, two, depending on the treatment environment. It can contain various numbers such as 4, 5, etc.

In addition, the distance (d) between the needle body 120 may include a range of 0.2mm to 0.4mm, the application example of the present invention is not limited to this value, and other ranges equivalent thereto may be included in the embodiment. .

Each line 10 in the form of a film according to an embodiment has a flat film shape in consideration of the thickness of the dermal layer, so when the line 10 in the form of a film is inserted into the skin, a part of each line protrudes to the outside of the skin, It can prevent insertion into the subcutaneous fat.

In addition, since the film-shaped barge-type machine 100 according to an embodiment is provided with a needle body 120 that fits the flat film-shaped barge-type model, it is possible to effectively insert the film-shaped barge into the dermal layer, Since the model of the needle body 120 is also manufactured in consideration of the thickness of the dermal layer, when the needle body 120 is inserted into the skin, the needle is not inserted into the subcutaneous fat layer, so there is an effect of reducing sequelae after the procedure.

In addition, in the film-shaped sheet insertion machine 100 according to an embodiment, a plurality of needles are arranged at regular intervals, so that even if the sheet thread insertion device is inserted only once, multiple film-shaped sheets 10 are simultaneously inserted into the dermal layer. Therefore, it is possible to shorten the time of the procedure and reduce the aftereffects of the procedure. In addition, since each line can be inserted at even intervals, a systematic and dense collagen network can be formed in the dermal layer.
