Description

Lifting thread for insertion into in-vivo < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a living body insertion body for lifting, and more particularly, to a living body insertion body for lifting, which comprises a wing-shaped protrusion on a surface of a thread, And at least one space portion formed at one side of the chamber so as to be continuously injected into the living body tissue and maintained in a state in which the tissue is extended.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biotissue thread for lifting used for extending and maintaining living body tissues in cosmetic surgery, dermatological surgery, cosmetic surgery and general surgery.

As modern medicine develops, the field of cosmetic surgery is rapidly developing, with the help of medicine, to form a part of the body that it possesses and to feel confident or to feel the satisfaction of oneself.

Particularly, in the case of the nose located in the center of the face among the parts of the body, the nose for increasing the nose is a typical field in cosmetic molding because it affects the first impression. In this case, various methods (e.g., methods using silicone implants or gore-tex, autologous cartilage, autologous fat, etc.) are used to naturally raise or shape the nose.

Among them, silicone implants are inserted into the nasal bridge, and the ear cartilage obtained from the patient's nose at the tip of the nose and the nasal cartilage are filled with the most common method, and there is little side effect reported.

However, the method of using the self-organization has relatively various advantages. However, it should be considered that a separate operation for collecting a part of the body should be performed, and there is a disadvantage that the physical characteristics and the absorption rate are not uniformly predicted exist.

Moreover, if cartilage retrieval is not sufficient and about 5 years after surgery, the formed nose shape is deformed (because the cartilage can easily move and the cartilage fixation thread may loosen and the cartilage position may change) There is a lot of cases in which reoperation is performed. Therefore, it is not an ideal molding method. In addition, there is a disadvantage that there is a lot of limitations in daily life because it causes swelling after surgery and the treatment period lasts at least a week.

Various nose forming methods and tools have been invented and developed to overcome the problems of the conventional nose forming method. In particular, Patent No. 10-0761921 entitled " Bioinjection Seal for Use in Anti-Press Multi-Fiber Adhesive Sealing Method for Biomechanical Stretching and a Tool for Inserting it into a Living Body " .

1 is a view showing a state in a living body insertion chamber for conventional nose formation.

Referring to FIG. 1, the patent document 10-0761921 discloses a human body insertion chamber 10 having a directional protrusion used for extending a part of a human body. The protrusion 12 has a wedge- And the protrusions 12 are formed of two sections 10A and 10B which are opposite to each other with respect to a reference point P on the seal axis, The biopsy device is inserted into the living body by the injection needle, and when the biopsied tissue is pulled out, the protrusion does not interfere with the tissue, and the tissue is stretched. When the pulling force is removed, the bioreactor resists the force Discloses a biocompatible thread for use in an anti-compression multifilament adhesion suturing method for soft tissue lengthening.

In the case of such a biotissue thread, the existing suture structure (a structure in which protrusions exist in both directions of the thread, disclosed in U.S. Publication No. 2005/0267532 (Surgical thread) This is significant in that it was used for the interbody abdominal multifilament adhesion suture for biomechanical extension.

However, in the case of using the biotooling chamber described in the above-mentioned Japanese Patent No. 10-0761921 for actual nose molding, (i) there are two kinds of protrusions which are necessarily operated in different directions in the thread, (Ii) because the thread for biopsy is made of a suture, there is a disadvantage in that the supporting force is very weak despite the presence of the bi-directional protrusion, (iii) the surface of the thread The surface area in contact with the living tissue is small due to the structure in which the wedge-shaped protrusion is present, so that it can not withstand the force that is to be re-entrapped due to the tissue elasticity. (Iv) Since the structure of the thread itself and both ends are pointed, After about 40% of patients, there was a serious side effect that the thread was protruding from the tip of the nose. Therefore, (v) the procedure using the biopsy room is not only very difficult for the specialist but also has a disadvantage that the patient 's satisfaction is also very low.

In order to solve various problems occurring during actual use of the above-described biotool, the inventor of the present invention has found that a wedge-shaped protrusion is formed on the surface of a thread made of a thread, a cylinder or an ellipse and a space formed on one side of the thread The inventors of the present invention have invented a living body insertion chamber which is injected into a living body tissue and can be maintained more effectively in a state in which the above-described tissue is extended.

In this process, the thickness of the lines and the size of the constituent elements shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

Structure of a biotissue thread

FIG. 2 is a side view showing a living body 100 according to the present invention. FIG. 3 (a) is a perspective view showing a living body 100 having a cylindrical shape according to an embodiment of the present invention, FIG. 3 (b) is a perspective view illustrating an elliptical living body insertion chamber 100 according to an embodiment of the present invention. FIG. 4 is a perspective view of a body 100 of a living body 100 according to an embodiment of the present invention. Sectional view showing the portion 110 and the protrusion 120 of the first embodiment.

The body 100 according to the present invention includes a body portion 110 which is basically made of a thread, a cylinder or an ellipse, a protrusion 120 which is formed by protruding in a wing shape on the outer peripheral surface of the body portion 110, And at least one space 130 formed at one side of the unit 110.

Particularly, such a body 100 for insertion may be divided into three sections: a first section composed of a body 110; A second section in which a protrusion 120 is formed on the body section 110; And a third section in which a space 130 is formed in the body 110 together with the protrusions 120.

At this time, The length of the first section is in the range of about 2.8 cm to about 3.2 cm, and the length of the second section and the third section is preferably in the range of about 3 cm to about 5 cm.

In one embodiment, the first section of the body 100 for insertion may be lifted (a method of inserting the absorbed thread under the skin to increase the sagging of the face and to restore the line and elasticity) It plays a role of bringing up the flesh and allowing it to enter the living tissue easily.

Therefore, it is desirable that the length of the first section is within the range of about 2.8 cm to about 3.2 cm to perform the above-mentioned function. It is noted that the first section is a region where the supporting force is improved from three weeks after the insertion into the living tissue.

In addition, it is preferable that the second section includes only protrusions that can support the living tissue while the living tissue grows in the space 130 described later.

The diameter of the first section and the second section is in the range of about 0.8 mm to about 1.2 mm, and the diameter of the third section is about 1.8 mm to about 1.2 mm. Preferably within a range of about 2.2 mm.

This is because, according to one embodiment of the present invention If the diameter of the living body insertion chamber 100 is less than about 0.8 mm, it is difficult to substantially support the living body in vivo. If the diameter of the living body insertion chamber 100 becomes larger than about 2.2 mm, And it is difficult to be used for molding such as nose shaping or face shaping.

On the other hand, although the diameter range of the body 100 for insertion is limited, the above diameter range is a recommended diameter in which threads or protrusions are not visible on the surface of the skin when applied to the face portion. When applied to other body parts other than the face portion It is possible to exceed the diameter range of the body 100 for insertion.

The protrusion 120 is formed to extend in a wing shape on the outer circumferential surface of the body 110. The protrusion 120 facilitates the insertion of the living body insertion chamber 100 into the living body as described later, And it plays a role of resisting the tissue elasticity so as to maintain the elongated state without returning by the elasticity of itself.

The projected size, width, helix angle, and spacing distance of the protrusion 120 are not particularly limited as long as the protrusion 120 can perform the above-described functions, but the spacing distance is preferably in the range of about 1 mm to about 2 mm.

Such a separation distance is suitable for the insertion of the protrusion 120 after the insertion of the living body 100 into the living tissue, and even if the range of the separation distance is larger or smaller than the above range, Please note that

The space 130 is formed on one side of the body 110. The space 130 may be formed of one or more pieces and may be configured to pass through one side of the body 110. [

In addition, the space 130 may be arranged to be arranged in one or more rows, and the living tissue may grow through the space 130.

Such a space 130 increases the biocompatibility and surface area of the body 100 for insertion and increases the surface area of contact between the body 100 and the living tissue to (i) (Ii) effectively resist forces that are reclosed by tissue elasticity, thereby (iii) maintaining the tissue more effectively in an extended state.

Although the space 130 has a rectangular parallelepiped shape in the drawing, it should be noted that the space 130 is not limited to a specific structure and may be used in various ways as needed. It should be noted that cylindrical or elliptical space portions may be formed depending on the shape of penetration.

On the other hand, such a body 100 for insertion may be composed of a medical suture.

In this case, the medical suture may be made of various materials such as nylon, polypropylene, polydioxanone, polycarprolactone, poly-L-lactic acid (PLLA) alloys containing platinum (Pt), platinum, alloys including titanium (Ti) and titanium, and the like, including polyglycolic acid (PGA), polyglycolic acid (PLGA), cat gut, gold Material.

Preferably, the living body insertion chamber 100 is made of a silicon material. The reason for this is that silicon material is widely used for medical use and particularly excellent in flexibility and support force than the suture material described above and thus has an excellent effect in supporting the elongated tissue in the state where the living body insertion chamber 100 is inserted in the living body Because.

That is, due to such a configuration, when the living body insertion chamber 100 is inserted in the living body and the living body is extended by applying a force, the living body tissue is stretched without any appreciable resistance. When the force applied to the living body tissue is removed, It is possible to maintain the state where the tissue is stretched for a long period of time because the body 120 and the space 130 resist the force of returning the tissue to its original state.

Therefore, the body 100 for insertion according to the present invention can be effectively used for plastic surgery, dermatological surgery, cosmetic surgery, and general surgery.

Principle and application status of the chamber

Fig. 6 is a view showing a state in which the living body 100 according to the present invention is inserted into the living tissue. Fig. 7 (a) shows the living body 100 according to the present invention, FIG. 7B is a view schematically showing a state where the living body insertion chamber 100 according to the present invention is applied to the nose region. FIG.

Referring to FIGS. 6 and 7, the operation principle and application state of the living body 100 according to an embodiment of the present invention will be described in detail.

Referring to FIG. 6, the living body insertion chamber 100 according to the present invention is inserted into a living body using a tool such as a needle (not shown). At this time, when the biocentric cell 100 is extended by applying a force to the tissue, the tissue is extended without any specific resistance. Then, in the case of removing the force applied to the tissue, in general, the tissue is returned to the original state by the elasticity of the tissue. When the living body insertion chamber 100 according to the present invention is inserted and positioned, Even if a force is applied, since the living body insertion chamber 100 is resistant to the force, it is possible to prevent the body tissue from returning to its original state.

Such an effect is obtained when the living body insertion chamber 100 has the wing-shaped protruding portion 120 and the space portion 130 formed at one side of the body portion 110, and these structures are combined with the living tissue in the extended state This is because the structural features resist the force of restoring the original structure.

Referring to FIG. 7, there is shown a state where at least one living body 100 according to the present invention is inserted and inserted into a living body.

In the case where one or more biocompatible chambers 100 are used in this manner, unlike the case of using one, the strengthened strength of the biocompatible tissue can be maintained more effectively.

At this time, the thickness, the length, and the separation distance between the living body insertion chambers 100 are different depending on the state of the patient or the tissue position. For example, in the case of general rubrication, It is possible to obtain an elongation effect by inserting about 4 to about 10 biopsy chambers 100 having a diameter of about 0.8 mm to about 2.2 mm.

Here, the diameter of the needle is preferably about 0.5 mm larger than the diameter of the body 100 for insertion.

It should be noted that the number of the living body insertion chambers 100 varies depending on the position of the living tissue to be used, and about four to ten living cells are suitable for the face region.

As described above, according to the present invention, by providing a wing-shaped protrusion on the surface of a thread made of a thread, a cylinder, or an ellipse, and one or more space portions formed on one side of the thread, It is possible to maintain a more effective state.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
