Lifting seal assembly with needle and cannula at the same time

The present invention relates to a lifting seal assembly having a needle and a cannula at the same time, and it is possible to conveniently increase the length of the main office by mounting a cannula and a needle providing a human body insertion function at both ends of the main body that serves as a lifting, respectively. It relates to a lifting seal assembly that ensures the convenience of the procedure.

The medical lifting thread, which was widely used in the past to provide a suture function during surgery, is now used for the purpose of cosmetic and plastic surgery to lift sagging skin due to aging.

The lifting thread is inserted into the dermis layer of the skin, particularly the face, in a state made of a melting thread such as PDO (Polydionaxone), PLLA, and PCL to lift the skin in a desired direction. In many cases, a protrusion made of , that is, a cog is formed.

Such a lifting thread is generally released in a state accommodated in a needle or cannula, which is a type of skin insertion tool.

There are various types of thread insertion tools, but two types, namely, a needle and a cannula, are widely used.

A needle (needle) is a tube having a hollow, and has a structure with an opening in a state in which the end is formed sharply. On the other hand, the cannula (cannula) is made of a hollow tube structure like a needle, compared to the needle, the end is blunt and the opening is formed in a part deviated from the end to an inner point.

The needle has a sharper end than a cannula, so it can be treated in more detail, but it has the characteristic of large bruising and swelling.

On the other hand, the cannula has a blunt end, which forms an entry point with a separate needle and then inserts it into the skin.

As such, the needle and the cannula have their own pros and cons, and in the actual operating environment, it is often decided by the skill and preference of the operator, that is, the doctor.

Since the lifting thread procedure is widely used, there are many cases where the length of the lifting thread is extended longer than necessary for the reason of maximizing the lifting effect. came to a situation where

However, in the actual operation environment, there is a need to treat a skin area longer than the allowable length of the lifting thread. A problem exists.

In addition, as mentioned briefly above, a needle and a cannula may be required at the same time in the same operating environment depending on the operating environment and the doctor's preference. hassle ensues.

There are various prior literatures in which a lifting thread and a cannula or needle are combined. The domestic patent No. 1391659, a medical thread and a medical thread insertion device, is coupled to at least one of a protrusion chamber having a plurality of protrusions on the surface, and both ends of the protrusion chamber. Including a mono-seal part, each of the protrusions has a structure in which a pair of incision grooves recessed inwardly from the surface of the protrusion seal part are spaced apart from each other at a predetermined interval, thereby providing an effect of relieving pain during the procedure. has been

However, this prior art also relates to a structure in which one insertion tool is mounted on one thread as described above, and when a needle or cannula is to be used according to the needs and environment of the operator's needs or the operation environment, the needle or cannula The inconvenience of having to obtain a separate installed thread followed.

Therefore, a needle and a cannula are mounted at both ends of a single thread at the same time to ensure the convenience of selection of the insertion tool, and in the actual procedure, a long treatment area can be conveniently operated and cut according to the situation. There is a need to develop advanced lifting seal assemblies.

The present invention has been devised to overcome the problems of the above technology, and by mounting a needle and a cannula at both ends of the head office, respectively, to ensure the convenience of selection of an insertion tool, as well as to ensure the convenience of selecting an insertion tool, the thread length is also made longer than the general length, so that the needle and cannula are provided Its main purpose is to provide a lifting seal assembly that can be used at the same time and can be operated integrally or cut and used to ensure convenience.

Another object of the present invention is to provide a structure of any one of a symmetrical type and the same inclined direction type with respect to both ends of the head office, but forming a cog to strengthen the fixing force and traction force of the head office.

Another object of the present invention is to provide a fixing force strengthening means having various structures at the end of the main cannula side.

An additional object of the present invention is to strengthen the traction and fixation power by giving physical properties by adding a specific composition to the head office.

In order to achieve the above object, the lifting seal assembly having a needle and a cannula at the same time according to the present invention, the head office extending to a certain length; Needle (needle) having an opening at the pointed end to accommodate the portion from one end of the head office to the first point in the hollow; It is characterized in that it includes a; to accommodate the portion from the other end of the head office to the second point in the hollow, the cannula (cannula) having an opening on one side around the blunt end than the end of the needle tube.

In addition, the head office is divided into first and second parts based on a point, wherein the first part has a cog inclined toward the end of the head office, and the first part is an end of the head office And it is characterized in that it is provided with a cog inclined to run through any one of the opposite ends of the end.

Additionally, at one end of the head office on the side of the cannula, it is characterized in that a knotted portion is formed in a state extending outward from the opening.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing refer to like elements.

1 is a cross-sectional view showing a basic embodiment of the lifting seal assembly of the present invention, Figure 2 is a cross-sectional view showing a modified embodiment of the lifting seal assembly of the present invention.

As can be seen from FIG. 1.2, the assembly of the present invention is based on providing a structure in which a needle 20 and a cannula 10 are mounted at one end of the head office 100 extended to a certain length.

First, the head office 100 is made of a melting thread such as PDO (Polydionaxone), PLLA, PCL like the known lifting thread. In FIG. 1, the length of the head office 100 seems to be short, but the actual head office 100 may have a longer length than this. In particular, as will be described later, the needle 20 and the cannula 10 at both ends of the head office 100 are provided. At the same time, it is more preferable to be made longer than the length of a general leafing seal due to the characteristics provided.

1 and 2, the needle 20 is wrapped around one side of the head office 100, that is, on the right side.

The needle 20 is also made of a tube type having a hollow 21 like a general needle, and the end has a pointed shape with an opening 22 formed on one side (end in FIG. 1) without a separate punching tool. It is possible to insert directly through the skin.

That is, the needle 20 of the present invention is the right side of the head office 100 based on FIGS. 1 and 2 in the state made of the same structure as the known needles, that is, from one end of the head office 100 to the first point. accommodating the area.

Additionally, as can be seen from FIG. 2, the opening 22 of the needle 20 is not necessarily limited to being formed at the end of the needle 20 as shown in FIG. It is also possible to be formed in the area around the end of the , because of this, it is also possible to perform a function similar to that of the cannula 10 as if the needle 20 according to FIG. 2 to be described later.

The cannula 10 of the present invention is also made of a tube/tube structure having a hollow 11 in the same way as a known cannula, and the end of the cannula 10 is blunt than the end of the needle 20 as is well known. It adopts a structure having the opening 22 on one side of the periphery, that is, at a point deviating inward from the end. At this time, it is possible to provide a pedestal 13 formed to have a larger diameter than other parts at the opposite end of the end side of the cannula 10. This prevents the cannula 10 from being fully inserted into the body and also prevents the operator from inserting the cannula 10 into the body. It can provide convenience for finger manipulation.

This cannula 10 accommodates the other end portion of the head office 100, that is, the portion from the left end to the second point with reference to FIG. 1 .

When the first and second points are once again described with reference to FIG. 1 in the present invention, the first point means the boundary point between the area covered by the needle 20 and the area not covered by the needle 20 among the right side of the head office 100, The second point may be interpreted as understanding the boundary point between the part covered by the cannula 10 and the part not covered by the cannula 10 among the left part of the head office 100 .

Additionally, referring to FIGS. 1 and 2 , it is possible for the head office 100 to include the cogs 101 and 102 similar to the known lifting seals. At this time, the head office 100 can be divided into two parts, the first and second parts 110 and 120, and the first part 110 and the needle 20 cover the area covered with the cannula 10. It is referred to as 2 parts 120 .

The first part 110 has a cog 101 inclined toward the end (cannula side) of the head office 100 is formed. At this time, as shown in FIG. 1 , the cog 101 includes a plurality of unit sets at regular intervals along the longitudinal direction in a state in which one or two pieces are made along the circumference of the first part 110 as one unit set. It is possible to form Alternatively, as shown in FIG. 2 , both sides of the cross-section of the first part 110 may be alternately formed. This structural pattern may be equally applied to the cog 102 of the two-part 120 to be described later.

The cog 102 of the second part 120 has a shape inclined toward the end (needle side) of the head office 100, and as a result, the first and second parts 110 and 120 have a symmetrical structure that faces each end. Regardless of whether the head office 100 is cut or not, in particular, the code 101 and 102 of the first and second parts 110 and 120 are all in the same direction in a general surgical method of bending and inserting the head office 100 in a straight line. It extends obliquely to face the

The necessity of a symmetrical structure of the above-described cogs 101 and 102 can be understood with reference to FIG. 3 .

In summary, the cogs 101 and 102 have end directivity (directionality) so that they can be easily inserted into the treatment site through the cannula 10 or the needle 20, and at the same time, it is possible to provide a firm body tissue fixation force. .

Hereinafter, the function and operation of the present invention will be described with reference to FIG. 3 .

Figure 3 is a conceptual diagram illustratively showing a facial area that has been lifted through the seal assembly of the present invention.

Figure 3 (a) is a view showing an embodiment of the present invention used integrally without cutting the seal assembly.

The operator can select any one of the cannula 10 or the needle 20 and insert the head office 100 subcutaneously as in (1). In FIG. 3 (a), the operator selects the cannula 10 first Insertion was exemplified. In this case, before inserting the cannula 10 subcutaneously, an entry point is punched at the point where (1) and (2) meet through a separate punching tool, so that the cannula 10 with a blunt end can be easily subcutaneously to be inserted into

When the operator inserts the cannula 10 in the direction (1) and then pulls it out, only the first part 110 remains subcutaneously along the same line as in (1). At this time, the cannula 10 can be withdrawn while passing the second part 120 and the needle 20. For this, the diameter of the needle 20 may be greater than the diameter of the cannula 10, and the needle 20 According to the order of insertion first between the cannula 10 and vice versa may be formed.

Thereafter, when the needle 20 is inserted into the above-mentioned entry point in a direction different from (1), that is, in a direction (2), and then the needle 10 is pulled out, the second part can be inserted as shown in (2).

As such, it is difficult to separate the needle 20 or cannula 10 inserted in the lower order from the main office 100 because the main body 100 connected thereto is already inserted subcutaneously when the needle 20 or cannula 10 is inserted subcutaneously and then pulled out. In order to do so, an incision space may be formed along the longitudinal direction from one end of the side of the needle 20 or the cannula 10 to the other end, which is inserted in the latter order, and it can be separated from the head office 100 through this incision space.

In addition, at the ends of (1) and (2), the first and second parts 110 and 120 may protrude out of the skin for a certain length, and the remaining protruding portions will be described later in (3) and (4) of FIG. 3(b). ), it is also possible to complete the procedure by inserting it under the skin in the reverse direction.

According to this, by inserting the first and second parts 110 and 120 in different directions through one and the same entry point, it is not only prevented from adding unnecessary punching work to the body, but also used integrally without cutting the head office 100 Therefore, it is possible to provide properties that can strengthen the traction and fixation of the skin.

The embodiment of Fig. 3 (b) shows a surgical method such as using two threads by cutting the head office 100.

Specifically, when the central portion of the head office 100 is cut, the first part 110 in which the cannula 10 is partially mounted and the second part 120 in which the needle 20 is partially mounted can be secured separately. have.

After that, the first part 110 is inserted in the (1) direction, the cannula 10 is taken out, and then the remaining protrusion of the first part 110 is reversed as in the (2) direction. In addition, the second part 120 is inserted in another part of the skin, that is, in the (3) direction, and then the needle 20 is taken out to form the second part 120 as in (3), and then the second part 120 is The procedure can be completed by inserting the remaining protrusion in the direction (4).

According to this method, it is possible to use the needle 20 and the cannula 10 at the same time based on a single head office 100, that is, a needle with a sharp end in the area requiring a more precise operation by the operator, for example ( Usability of the seal assembly by inserting the second part 120 equipped with 20) and inserting the first part 110 equipped with the cannula 10 having a blunt end in the site for less bruising. In addition to maximizing the effect, various shapes such as 'C' can be used to lift the treatment area.

Additionally, in the case of cutting and using the head office 100 as shown in FIG. 4(b), between the first and second points in the head office 100 to ensure the convenience of cutting the head office 100, for example, in the central part of the head office 100 It is also possible to assist in easily separating the head office into the first and second parts 110 and 120 without a separate tool by providing a cutting part recessed inward and the cutting part performing a role like a kind of incision line.

In summary, according to the seal assembly of the present invention, it is possible to not only guarantee the convenience of the operation, but also provide the advantage of increasing the lifting effect of the treatment site by forming it longer than the length of the existing thread.

4 is a cross-sectional view showing a detailed structure formed at one end of the cannula-side head office.

4 shows that various three-dimensional structures are formed at the end of the head office 100 on the side of the cannula 10, that is, the structure additionally provided in FIG. 4 inserts the cannula 10 to subcutaneously the head office 100 When the cannula 10 is withdrawn from the subcutaneous tissue after being inserted together, it prevents the main body 100 (the first part) inserted subcutaneously from being pulled out together with the cannula 10 while performing a strong anchoring point function in the inserted subcutaneous tissue. It can serve as a kind of anchor point.

First, according to the embodiment of Figure 4 (a), there is a protruding portion extending outside the opening 12 of the cannula 10 at the end of the head office 100 (first part) on the side of the cannula 10, this protruding portion presents a knotted structure, and the knotted portion is referred to as a knot 150 .

This knot 150 is not only larger in diameter than other parts of the head office 100, but also larger than the diameter of the opening 12, so that when the cannula 10 is withdrawn from the skin, the head office 100 is aligned along the cannula 10. As well as preventing the problem of being pulled out, since it can be made in a post-process of knotting the end of the head office 100 without separate molding, it provides a characteristic that guarantees the convenience of manufacturing.

The embodiment of Fig. 4 (b) shows the rolling portion 130 in which the portion protruding outside the opening 12 of the cannula 10 in the head office 100 (the first part) is rolled.

The rolling portion 130 is also formed by rolling the protruding end portion without separate molding like the knot portion 150, and is processed to have a larger diameter or volume than other portions of the head office 100, providing convenience in manufacturing and It can ensure its role as an anchor point in the subcutaneous tissue.

Figure 4 (c) shows that in the manufacturing process of the head office 100, the end of the cannula 10 side head office 100 is formed to be thicker or larger in diameter than other areas, and this area is expanded part 140 say

Since this extension 140 is formed to have a larger diameter than other parts of the head office 100 from the time of manufacture, it serves as an anchor point under the skin while solving the problem that the parts around the head office are cut off when unfolded by an external force or when a knot is made. It is possible to perform

Additionally, the extension 140 includes at least one extension protrusion 141 that protrudes, and it is also possible to provide a function of strengthening the fixing force under the skin through the extension protrusion 141 .

In summary, the three embodiments according to FIG. 4 have a difference in the manufacturing process or shape, but with the cannula 10 by securing a sufficient diameter of the end portion of the head office 100 (first part) on the cannula 10 side. It provides the function of securing the fixation force while preventing it from being pulled out of the skin.

5 is a flowchart illustrating a process for manufacturing a functional material contained in the head office.

As another embodiment, the head office 100 of the present invention may include a functional material including pectin to enhance the adhesion of the lifting thread, thereby assisting in fixing and traction to the living tissue.

This functional material is manufactured through a mixing 1 solution preparation step (S100), a mixture 2 solution preparation step (S110), a mixture 3 solution preparation step (S120), a mixture 4 solution preparation step (S130), and a functional material completion step (S140) can be, and the specific method for this is as follows.

First, the mixing 1 solution preparation step (S100) is a process of preparing a mixture 1 solution by mixing 80 to 95 parts by weight of water and 5 to 20 parts by weight of pectin.

Here, pectin is a colloidal polysaccharide widely distributed in plants, and is abundant in leaves, stems, fruits, etc., in a small amount in wood, and is also contained in seaweed. Such pectin can be dissolved in water to represent a highly viscous colloidal solution and impart adhesiveness.

Next, the mixed 2 solution preparation step (S110) is a process of preparing a mixed 2 solution by mixing 85 to 95 parts by weight of dimethyl sulfoxide and 5 to 15 parts by weight of N-hydroxysuccinimide (NHS). Here, dimethyl sulfoxide serves as a solvent for dissolution of NHS, and NHS as a crosslinking agent activates the carboxyl group of pectin by esterification reaction to produce an NHS-pectin intermediate, which will be described later. It can bind more strongly with gelatin.

Then, the mixing 3 solution preparation step (S120) is 30 to 60 parts by weight of the mixture 1 solution, 30 to 60 parts by weight of the mixture 2 solution, and 1 to 10 parts by weight of EDC (1-ethyl-3-(3-dimethyl aminopropyl)carbodiimide) After mixing, it is a process of preparing a mixed 3 solution by stirring at 20 to 30° C. for 20 to 30 hours, and the mixed 4 solution preparation step (S130) is 70 to 90 parts by weight of 0.1M PBS (Phosphate buffered solution), 10 to 10 parts by weight of gelatin Mixing 30 parts by weight is the process of preparing a mixed 4 solution.

Here, EDC serves as an adjuvant capable of further improving the above-described NHS-pectin intermediate and crosslinking between pectin and gelatin. In addition, 0.1M PBS serves as a solvent for dissolving gelatin, and gelatin is cross-linked with pectin by NHS and EDC. It is a kind of induced protein obtained by treatment with alkali. Here, 0.1M means a molarity of 0.1.

Finally, the functional material completion step (S140) is a process of mixing 40 to 60% by weight of the mixed 3 solution and 40 to 60% by weight of the mixed 4 solution and then heating at 40 to 60° C. for 10 to 20 hours to complete the functional material to be.

The functional material manufactured through this process is manufactured through a crosslinking reaction of pectin and gelatin, so it is environmentally friendly and harmless to the human body.

In addition, the functional material may further include mussel foot protein to further improve fixation and adhesion to living tissue.

Specifically, relative to the total weight of the functional material, the mussel foot protein may be included in a ratio of 1 to 10% by weight, and the mussel foot protein is included in the middle of the functional material manufacturing process, mixed in the finished functional material, or coated on the surface It may be included in the functional material in such a way that there is no specific limitation thereto.

At this time, the mussel foot protein has a shape with a flat pad attached to the end of a thin thread called byssus, and is composed of more than 12 types of proteins. At this time, proteins named Mfp-1 (Mytilus foot protein-1), Mfp-3, and Mfp-5 are present in a high proportion in the mussel foot protein, and 3,4-dihydroxyphenyl-L-alanine (DOPA) is present in these proteins. ) is very rich in modified amino acids called

This mussel foot protein has a strong coating ability and adhesion, and especially has excellent adhesion in water, and since it is a protein component, it can have high functionality even when applied to the body. Therefore, the mussel foot protein may be included in the functional material to help improve the fixation and traction power of the functional material to the living tissue.

As described so far, the configuration and operation of the lifting seal assembly having the needle and the cannula according to the present invention are expressed in the above description and drawings, but these are merely examples and the spirit of the present invention is reflected in the above description and drawings. It is not limited, and various changes and modifications are possible without departing from the technical spirit of the present invention.
