Description

A needle assembly for thread lifting that provides a safe and strong fixation point and a thread lifting procedure using the same

The present invention relates to a needle assembly used for thread lifting and a thread lifting procedure using the same, which allows a lifting thread to be easily mounted on a needle while using an existing lifting thread, and each needle is mounted on both ends of the lifting thread It relates to a needle assembly capable of providing a strong fixation point in a lifting procedure in a state of being lifted, and a thread lifting procedure using the same.

Recently, as interest in skin beauty increases, interest in various procedures for removing wrinkles on the face or neck and maintaining elastic skin is increasing.

Treatments for removing wrinkles and maintaining skin elasticity include facial lift, filler insertion, and laser skin regeneration, as well as injecting a thread that is harmless to the human body to increase elasticity and volume in areas such as nasolabial folds and chin, so that it can be lifted easily without going through a surgical procedure. Thread lifting technology is being introduced.

More specifically, thread lifting involves inserting a thread formed with small protrusions such as a rose thorn into the subcutaneous soft tissue and pulling it to avoid wrinkles and give elasticity to a desired area.

That is, a hole with a diameter enough to insert a thread is formed inside the long and thin needle with a handle (H) on one side, and the thread is inserted in the hole from the back of the needle to the front in the longitudinal direction and then pulled out from the tip of the needle. Prepare the needle assembly by fixing some of the thread that has escaped to the outer peripheral surface of the needle through a medical sponge.

And referring to FIG. 1, the needle assembly for lifting is subcutaneously inserted obliquely to the required site, and as the needle (N) is inserted subcutaneously, the medical sponge (S) is pushed backward, and the lifting thread (T) is the needle of the needle. It is inserted subcutaneously with advancing.

Afterwards, when the inserted needle is pulled out in the opposite direction to the insertion direction, the lifting thread remains under the skin, and the operator removes wrinkles by pulling the lifting thread exposed to the outside of the skin.

When the procedure is completed, the externally exposed thread is cut, and the thread remaining under the skin is fixed in a pulled state to maintain the wrinkle improvement effect.

For reference, the needle used in the above procedure is also called a cannula.

On the other hand, the fixation point of thread lifting is important in order to expect the desired treatment effect in the thread lifting procedure. In other words, it is important to have a fixed point because it must be firmly fixed at the fixed point to prolong the maintenance period of the lifted state, and also to support the force in the opposite direction to the movement of tissue caused by aging and gravity.

For this reason, in the above-mentioned thread lifting procedure, another lifting thread is equally inserted at the point where the lifting thread is subcutaneously inserted, and then the two exposed threads are tied and knotted to make a fixed point (see Fig. 2) ).

However, in the case of the above-mentioned lifting procedure, two lifting threads must be used, and with each thread inserted into the skin, the exposed extremities are tied together and knotted to make a fixation point, so the procedure is not easy. It often happens that the end of the knot at the fixing point is not neat.

To solve this problem, by integrating the needles at both ends of one lifting thread, first insert the needle on one side subcutaneously, then pass the needle through the other side, cut one side of the lifting thread exposed together, and remove the needle on the other side. A procedure is introduced in which one side of the needle is inserted at the same point where the needle is inserted and the other side of the lifting thread, which is also exposed, is cut and then lifted by pulling each end exposed from the thread. In this case, the midpoint of the lifting thread is It acts as a fixed point like a knot in the existing procedure.

This procedure has the advantage of being able to easily create a fixation point and providing a strong fixation force compared to the existing procedure. However, the needle used for the procedure has a sharp tip, so there is a risk of damage to blood vessels or nerve tissue during the procedure.

On the other hand, as a prior art related to thread lifting, there is Registered Patent No. 10-2069250 (Jan. 16, 2020) "Needle Assembly for Face Lifting", the patent suggests an improved needle assembly configuration, but the needle assembly is As a needle assembly used for a lifting procedure using a cannula mentioned in the prior art, it is different from the procedure method of the present invention described below, and has a clear structural difference from the needle assembly of the present invention.

In addition, Patent Registration No. 10-1532704 (June 24, 2015) "Cannula for suture lifting" is also used for the lifting procedure using the cannula mentioned in the prior art, which is different from the procedure of the present invention described below, It has a clear structural difference from the needle assembly of the invention.

Accordingly, the present invention is designed in consideration of the advantages and disadvantages of each lifting procedure using a cannula and a lifting procedure using a needle assembly integrating a needle and a lifting thread,

An object of the present invention is to provide a needle assembly and a thread lifting procedure that can provide a safe and strong fixation point while using an existing shared lifting thread during a thread lifting procedure.

In addition, the purpose of improving the structure of the needle is to provide a needle assembly that allows a lifting thread to be easily attached to the needle, and furthermore, a needle assembly and thread lifting procedure that can minimize damage to blood vessels and nerve tissue during the procedure is intended to provide.

A first needle extending in the longitudinal direction, a ring is formed at the rear end, and the end is round finished;

A second needle extending in the longitudinal direction and having a ring formed at the rear end and rounded at the end, and

A plurality of thorns are formed on the outer circumferential surface and it is characterized in that it comprises a lifting thread mounted on the rings of the first and second needles.

In addition, the lifting thread has a first invisible portion in which no thorn is formed, a visible portion in which a thorn is formed following the first invisible portion, and a second invisible portion in which a thorn is not formed following the visible portion in both end directions with respect to the center. It is characterized in that it consists of an invisible part.

And the needle assembly for lifting the thread further includes an auxiliary body for inserting the thread for lifting into the rings of the first and second needles,

The auxiliary body is formed by bending a wire and is characterized in that the front part has a tapered ring shape.

Next, the thread lifting procedure of the present invention using the above-mentioned needle assembly is,

and mounting the lifting thread on the loops of the first and second needles.

A step of making a hole in the puncture point to inject the lifting thread,

Inserting and advancing the first needle into the skin through the puncture point in which the hole is formed, and extracting the first needle to the discharge point formed by drilling a hole in advance to the place where the first needle will come out;

Cutting the lifting thread on the first needle coming out of the skin;

Inserting and advancing the second needle into the skin as the puncture point, and extracting the second needle to the discharge point formed by drilling a hole in advance to the place where the second needle will come out;

and lifting the skin by pulling each lifting thread coming out of the skin.

According to the above configuration, it is possible to provide a strong fixing point without knotting or sutures while using a common lifting thread used in a lifting procedure using a cannula, and a needle assembly in which the needle and the lifting thread are integrated. As it is safer than the lifting procedures used , optimal lifting effects can be expected compared to the existing thread lifting procedures, so it is possible to provide high-quality services to consumers.

In addition, according to the needle assembly structure proposed in the present invention, it is possible to easily combine the needle with the lifting thread, and it is possible to minimize damage to blood vessels and nerve tissue during the procedure.

1 is a simplified diagram for explaining a lifting procedure using an existing cannula.
Figure 2 is a view for explaining a method of forming a fixed point with a knot in a lifting procedure using an existing cannula.
3 and 4 are views for explaining the configuration of the needle assembly according to the present invention.
Figure 5 is a simplified view for explaining the thread lifting procedure using the present invention.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

As shown in Figures 3 and 4, the needle assembly of the present invention is made of two needles (10, 20) and both ends of the lifting thread 30 to which the respective needles are mounted.

The lifting thread used in the present invention is a lifting thread used in a lifting procedure using an existing cannula rather than a separately manufactured thread for the present invention, but a two-way cog thread is preferable.

For reference, the lifting thread used in the thread lifting procedure is classified into a straight thread, a spiral thread called a tornado lifting thread, and a cog thread with a number of thorns formed in the middle of the thread. In particular, the cog thread has a thorn-shaped protrusion in the middle of the thread, so it can pull the skin tissue, and it has the advantage that it can produce an excellent lifting effect even if a small number of threads are inserted compared to other threads.

Such a cog seal has a one-way cog seal in which thorns are formed in only one direction and a two-way cog seal in which thorns are also formed in the opposite direction.

As mentioned above, in the present invention, a cog seal is used as a lifting thread, but it is preferable to use a cog seal in both directions.

On the other hand, the lifting thread can be made of biodegradable PDO (Polydioxanone). Since the PDO component promotes collagen remodeling, it has an effect of maintaining the lifting power even after the lifting thread melts and disappears.

In addition to PDO, PLLA (Poly L-Lactic Acid) is also used. PLLA (Poly L-Lactic Acid) is a biodegradable polymer that induces autologous collagen regeneration and is known to give skin elasticity and volume.

Referring back to FIG. 3 , the first needle 10 and the second needle 20 to which both ends of the lifting thread are mounted respectively extend in the longitudinal direction and have rings 15 and 25 formed at the rear end, the leading end (10A, 20A) It is preferable that the surface is finished to be round.

That is, in the case of the needle assembly in which the needle and the lifting thread described as one of the prior art are integrated, the tip of the needle is sharply formed and inserted and advanced while directly puncturing the skin. In this case, the risk of damage to blood vessels or nerve tissue in the skin There is this.

Accordingly, in the case of the first and second needles employed in the present invention, the tip (10A, 20A) is finished with a round surface to reduce the risk of damage to blood vessels or nerve tissue in the skin.

And, in the present invention, the first and second needles are not formed integrally with the lifting thread, but are designed so that the operator mounts the lifting thread to each needle during the procedure.

Accordingly, the first and second needle rear ends preferably have rings 15 and 25 for the lifting thread to pass through and to be mounted, and an auxiliary for easily inserting and mounting the lifting thread 30 into the needle loop. A sieve 40 is provided.

The auxiliary body is completed in a specific shape by bending a wire of a specific length a number of times, and may be completed in various shapes, but in the completed shape, the front portion 40A is preferably formed in a tapered ring shape.

By inserting a part of the lifting thread into the corresponding ring, and inserting the tapered ring front part 40A of the auxiliary body 40 into the loops 15 and 25 of the first and second needles in a state in which the thread part is inserted, The lifting thread is mounted on the first and second needles.

The auxiliary body 40 is introduced because it is difficult to insert the lifting thread into the ring of the first and second needles, that is, the small hole, and it is preferable that the ring formed in the auxiliary body is larger than the ring of the first and second needle And, it is preferable that the front portion 40A of the ring is tapered so that the ring formed on the auxiliary body is easily inserted into the ring of the first and second needles.

Referring to FIG. 3 , in the case of the auxiliary body, a ring shape was completed in a diamond shape while bending the wire 5 times.

Next, in the case of the two-way cog seal used in the present invention, the first invisible part 31 in which no thorns are formed in both end directions with respect to the center of the thread, and the visible part in which thorns are formed following the first invisible part (32) and the second non-visible portion 33 in which no thorns connected to the visible portion are formed.

That is, the two-way cog seal, which is the lifting thread 30 used in the present invention, is symmetrical with respect to the center of the thread, and includes the first invisible part 31 - the visible part 32 - the second invisible part 33 .

In addition, the first invisible part 31 is formed as a section with a length of 1 cm, the subsequent visible part 32 is a section with a length of 5 cm, and a thorn is formed in the corresponding section, and the subsequent second invisible part 33 is a thorn. It is formed over a section of 5 cm length equal to the part. And, following the second invisible part, a knot 34 for knotting with the first and second needles is formed, and the knot 34 may be included in the second invisible part.

Accordingly, during the procedure, the operator inserts both ends of the lifting thread into the loops 15 and 25 of the first and second needles using an auxiliary body and knots the first needle 10-lift thread 30-made 2 Complete the needle assembly consisting of the needle 20 (see [A] in FIG. 4).

For reference, in the method of mounting the lifting thread to the needle, the lifting thread is inserted into the needle loop (15. 25) and then knotted so that the lifting thread is connected to the needle, but depending on the method, the first And it is also possible to connect the lifting thread to the needle by pressing and compressing the ring in a state in which the lifting thread is inserted into the loop (15. 25) of the second needle.

Of course, in addition to the above-mentioned method, unlike the existing ones, the first and second needles without rings 15 and 25 are prepared, and a lifting thread is inserted into the empty needle body from the rear end of the needle, and the rear end of the needle is pressed and pressed in the inserted state. It is also possible to consider a method of connecting the lifting thread to the needle (see [B] in FIG. 4).

The thread lifting operation method using the needle assembly of the present invention configured as described above with reference to FIG. 5 is as follows,

First, as mentioned above, by mounting a lifting thread on the rings of the first and second needles, a needle assembly consisting of 'first needle-lifting thread-second needle' is completed.

Next, using a puncture needle or the like, a hole is made in the skin of the face to be subjected to the lifting procedure, that is, the puncture point P1 where the lifting thread will be injected. For reference, the insertion point where the needle is inserted into the skin such as the face, that is, the puncture point (P1) and the discharge point (P2) where the needle penetrates the skin are marked in advance.

Then, the first needle is inserted into the skin through the puncture point where the hole is formed, and the first needle is pulled out to the opposite side, that is, the discharge point (P2) by advancing the required length. In this case, the first needle inserted into the skin in a state in which a hole is drilled in advance at the discharge point is pulled out to the corresponding discharge point.

Thereafter, the lifting thread 30 connected to the ring of the first needle 10 is cut to separate the lifting thread and the first needle. At this time, the visible part of the lifting thread is inserted into the skin.

Next, the remaining second needle 20 is inserted into the skin at the puncture point P1, and the second needle 20 is advanced to the other side in the other direction in which the first needle has advanced to the discharge point P2 formed by drilling a hole in advance on the opposite side. ) and then cut the lifting thread 30 connected to the ring of the second needle to separate the lifting thread and the second needle. Also in this case, the visible part of the lifting thread is inserted into the skin.

When the procedure proceeds in this way, a lifting thread is inserted into the skin in a V-shape based on the puncture point (P1), and the distal end is exposed to the outside of the skin. It will lift the skin.

And, as confirmed in [C] of FIG. 5, the puncture point P1 functions as a strong fixation point in this procedure. Compared with a lifting procedure using a conventional cannula, the operator needs to tie a knot to make a fixation point there will also be no
