The present invention relates to a member for inserting a living body and an injection device for injecting the same into a living body, and more particularly, a screw or spiral protrusion on a surface of a member having a thread shape or a cylindrical shape; And by providing a tooth groove or a concave-convex structure formed in the protrusions, and relates to a living body insertion member that can be continuously injected in the living tissue soft tissue and extends the tissue and the injection mechanism for injecting it into the living body.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a member for insertion of a living body used for the extension and maintenance of living soft tissue in plastic surgery, dermatological surgery, cosmetic surgery and general surgery, and an injection device for injecting the same into a living body.

With the development of modern medicine, there is a rapid development of the cosmetic surgery field where the help of medicine can be used to shape a part of the body that one has and to feel confident or satisfied.

In particular, the nose located in the center of the face of the part of the body depends on the first impression, the nose molding to raise the nose can be said to be a typical field in cosmetic molding. In this case, various methods are used to naturally raise or shape the nose (eg, using silicone implants or Gore-Tex, autologous cartilage, autologous fat, etc.).

Among them, silicone implants on the nose and filling the ear cartilage and nose cartilage obtained from the patient's body at the tip of the nose are the most common and stable surgical methods with few reported side effects.

However, the method of using autologous tissues has relatively various advantages, but it is necessary to bear the separate procedure of taking a part of one's body, and the disadvantage that the physical characteristics and absorption rate are not uniformly predicted. exist.

Moreover, when cartilage is not sufficient and about five years after surgery, the shaped nose is deformed (because the cartilage can move easily and the thread holding the cartilage can be loosened and the cartilage position can change). Since many cases have been reported to perform reoperation, this is not an ideal cosmetic method. In addition, there is a lot of swelling after the operation and the treatment period takes at least a week, so there is a lot of obstacles in daily life, there is a disadvantage that there are many restrictions.

In order to solve the problems with the existing nose molding method, various nose molding methods or tools have been invented and developed.

Therefore, the definitions of these terms should be described based on the contents throughout this specification.

Structure of Biometric Insertion Member

FIG. 2 is a view illustrating a biological insertion member 100 according to an exemplary embodiment of the present invention, and FIGS. 2A to 2F illustrate first to sixth elements of the biological insertion member 100, respectively. It is a figure which shows embodiment. Referring to Figure 2 will be described in detail a member 100 for insertion of a living body according to an embodiment of the present invention.

Biological insertion member 100 according to the present invention basically comprises a body portion 110 made of a yarn shape or a cylindrical shape; And a protrusion 120 formed to extend in a spiral shape along an outer circumferential surface of the body portion (see FIG. 2 (a)).

At this time, the diameter of the body portion 110 of the biological inserting member 100 is preferably in the range of about 0.1mm to 0.8mm, for this reason, if the diameter of the biological inserting member 100 is less than about 0.1mm Substantially, it is difficult to support the tissue in vivo, and when the diameter of the bio-insertion member 100 is larger than about 0.8 mm, the size of the member becomes large and it is difficult to be used for molding such as nose molding. .

Protruding portion 120 is formed to extend spirally along the outer circumferential surface of the body portion 110, as will be described later, to help the biological insertion member 100 is more easily injected into the living body and artificially extended living body It plays a role of resisting tissue elasticity so that the tissue can be maintained in an extended state without being returned by its elasticity. Note that the protrusion 120 is not particularly limited as long as the protrusion 120 can perform the above-described role, and the protrusion size, width, spiral angle, and separation distance.

Biological insertion member 100 according to the present invention may further include a tooth groove or concave-convex structure 130 formed on the surface of the protrusion 120 (see Fig. 2 (b)).

Tooth groove or concave-convex structure 130 is configured to increase the biocompatibility and surface area of the biological insertion member 100, and increases the surface area in contact with the biological insertion member 100 and the living tissue (i) tissue attachment Improves sex and (ii) effectively resists the force to be retracted by tissue elasticity and thereby (i) effectively maintains the tissue in an extended state.

It is noted that the tooth groove or the concave-convex structure 130 is not necessarily limited to a specific structure but may be variously changed and used as necessary.

On the other hand, such a biological insert member 100 may be composed of a medical suture.

At this time, the medical suture may use a variety of materials to increase the adhesion while increasing the adhesion and elasticity with human tissue, specifically, nylon, polypropylene, polydioxanon, polycarprolacton, poly-L-lactic acid (PLLA), polyglycolic acid (PGA), poly-lactic-glyolic acid (PLGA), cat gut, gold (Au), alloys containing Au, platinum (Pt), alloys containing platinum, alloys containing Titanium (Ti) and Titanium It may be made of a material.

Also preferably, the biological insertion member 100 may be made of a silicon material. This is because the silicone material is used in various ways for medical purposes, and in particular, the flexibility or the supporting force is better than that of the above-described suture material, and thus exhibits an excellent effect of supporting the extended tissue in the state in which the insert member 100 is inserted into the living body. to be.

That is, due to such a configuration, the tissue is stretched without resistance when the biological insertion member 100 is applied to the biological tissue in a state where the biological insertion member 100 is inserted in the living body, and the protrusion is removed when the force applied to the biological tissue is removed. 120 and the tooth groove or the concave-convex structure 130 can resist the force of the tissue to return to its original state, so that the tissue can be continuously maintained in an extended state for a long time.

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

2 (c) to 2 (f) are views showing various embodiments of the biological insertion member 100. The biological inserting member 100 shown in FIGS. 2 (c) to 2 (f) is different from the biological inserting member 100 shown in FIGS. And only the additional effects caused by this will be described.

Biological insertion member 100 shown in Figure 2 (c) is a body portion 110 made of a yarn shape or cylindrical; And a protrusion 120a protruding from the outer circumferential surface of the body portion. In addition, the biological insertion member 100 illustrated in FIG. 2 (d) includes a tooth groove or an uneven structure 130 formed on an end side surface of the protrusion 120a.

In this case, the protrusion 120a is not formed in a spiral shape along the outer circumferential surface, but is provided in a form in which the disc-shaped protrusions individually protrude along a specific interval. However, it is to be noted that the protrusion and the structure may be changed as necessary. That is, although the protrusions are shown in the shape of a disc in the drawings, a plurality of protrusions may be formed, such as a plurality of cylinders and dots.

The biological inserting member 100 illustrated in FIG. 2E shows a structure in which both ends of the biological inserting member 100 are divided into one or more strands. Although both ends of the biological inserting member 100 are illustrated as being divided into four strands in the drawing, it should be noted that one end may be divided into only one or more strands (for example, two strands).

According to this configuration, the living body insertion member 100 can be moved in any state in the state inserted into the body to prevent secondary protruding from the tip of the nose or the skin and also to prevent the pain caused by the pain sensory organs concentrated on the skin. It becomes possible.

Figure 2 (f) is a biological insertion member 100 shown is a body portion 110 made of a yarn shape or cylindrical; Protruding portion 120 is formed to extend in a spiral along the outer peripheral surface of the body portion; And a sawtooth groove or uneven structure 130 provided at the end of the protrusion 130. However, it is characterized in that the protrusions 120 extending in a spiral shape on the basis of a specific reference point M extend in opposite directions (A direction, B direction).

In this case, it is noted that the reference point M may be an intermediate point of the biological inserting member 100 and may be located at the distal end of the biological inserting member 100 according to a user's need. For example, when the reference point M is located at the distal end, the whole insertion member 100 may be provided with one direction (A direction) protrusion, and only the distal end may be provided with the opposite direction (B direction) protrusion. In this case, when a predetermined time has elapsed while the biological inserting member 100 is inserted into the body, the spiral protrusion is formed only in one direction, thereby moving through the groove to prevent protruding from the tip of the nose or the skin. Will be able to perform

On the other hand, although not shown, one or both ends of the biological inserting member 100 may be provided with a rough surface such as an uneven portion, a protrusion, and a curved portion at its cross section.

Note that such a rough surface may be naturally formed in the process of cutting to use the bio-insertable member 100, or may be formed in advance in the process of manufacturing the bio-insertable member 100 as necessary.

When such a rough surface is provided at one end or both ends of the bioinsertion member 100, the surface area is increased to improve tissue adhesion, and the pressure applied to both ends of the bioinsertion member 100 is reduced to insert the living body. It is possible to prevent the dragon member 100 from protruding out of the skin.

Principle of operation and application state of biological insertion member

Figure 3 is a view showing the action when the insertion member 100 according to the present invention is inserted into the biological tissue, Figure 4 is a biological insert member 100 according to the present invention configured in a roll form 5 is a diagram schematically illustrating a state in which the bio-insertable member 100 according to the present invention is applied to a living tissue soft tissue extension surgery, and FIG. 6 is a bio-insertable member according to the present invention. 100 is a diagram schematically illustrating the steps of applying the parabolic procedure.

3 to 6 will be described in detail the operation principle and application state of the member 100 for insertion of a living body according to an embodiment of the present invention.

Referring to FIG. 3, the biological insertion member 100 according to the present invention is inserted into a living body using a tool such as a needle (see FIG. 3A). At this time, in the case where the biological insertion member 100 is extended by applying a force to the tissue of the inserted portion, the tissue is extended without special resistance (see FIG. 3 (b)). Then, when the force applied to the tissue is removed, the tissue is returned to its original position by the elasticity of the tissue in general. When the bio-insertion member 100 according to the present invention is inserted and positioned, the tissue is returned by the elasticity. Even if a force to be applied is applied, the body insertion member 100 is resistant to the force, thereby preventing the body tissue from returning to its original state (see FIG. 3 (c)).

The effect is that the insert member 100 has a helical protrusion 110 and the tooth groove or concave-convex structure 130 is provided at the end of the protrusion, and these structures are combined with the biological tissue in the extended state Because of its structural features, the tissue resists the force to return to normal.

Referring to Figure 4, it can be seen that the living body insertion member 100 according to the present invention is provided in a form wound on a roll. In this case, the use unit may be configured to be used by cutting the required length within the range of 0.5cm to 6cm.

At this time, it is noted that the different types of biological inserting members 100 may be repeatedly wound on a roll, or only the same type of biological inserting members 100 may be wound on a roll. In particular, the bio-insertable member 100 wound on the roll is only one embodiment, and in some cases, may be used in a form that is inserted into a needle in advance and cut to fit a use unit. Be careful.

Referring to FIG. 5, a state in which one or more biological insertion members 100 according to the present invention is used and inserted into a living body is illustrated.

When one or more biological inserting members 100 are used in this manner, they have a significantly stronger resistance strength than when one is used, so that the extended state of the biological tissues can be more effectively maintained.

In this case, the thickness, length, and separation distance between the bioinsertion member 100 and the bioinsertion member 100 are different according to the condition or tissue position of the patient to be treated. For example, in the case of general ablative surgery, 21 gauge By using a needle, the extension effect may be obtained by inserting about two to eight biological insertion members 100 having a diameter of about 0.3 mm within a range of about 5 mm.

Referring to FIG. 6, a step of applying the bio-insertable member 100 according to the present invention to the fusion procedure using the bio-insertable member 100 supplied in the form of being inserted into the syringe or inserted into the syringe in advance is outlined. It is shown.

Specifically, the insertion member 100 is inserted into the injection needle in a state in which the injection needle 100 is inserted or inserted into a portion to be extended. Then, when the biological insertion member 100 inside the injection needle is slowly pushed while rotating, the biological insertion member 100 is inserted into a portion to be extended along the spiral protrusion 120. At this time, when the injection needle is pulled out while the biological insertion member 100 is inserted into the body, only the biological insertion member 100 is inserted into the body. After repeating this process as necessary, if the nose tip is extended to the required level, one end of the biological insertion member 100 is naturally buried inside the skin. In such a state, as described above, the tissue 110 is naturally maintained in the extended state due to the toothed groove or the uneven structure 130 provided at the protrusion 110 of the biological insertion member 100 and the end of the protrusion. Effect occurs.

As described above, according to the present invention, a screw or spiral protrusion and a sawtooth groove or uneven structure formed on the protrusion are provided on the surface of a member having a thread shape or a cylindrical shape so as to be injected into a living soft tissue to extend the tissue. The effect can be maintained more effectively in the state.
