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 in that there are many obstacles in the postoperative period 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 " .

In this process, the thicknesses of the lines and the sizes of the components 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 member for biomechanical insertion

2 is a sectional view of a part of the surface of the member 10 for biometrics according to an embodiment of the present invention. 3 is a perspective view of a member 10 for biometrics according to an embodiment of the present invention. 4 is a front view of the member 10 for biometrics according to an embodiment of the present invention. 5 is a partial perspective view of the member 10 for biometrics according to the present invention.

2 to 6, the body-insertable member 10 according to the present invention includes a body portion 11 which is basically formed in a cylindrical shape or a cylindrical shape, And a cutting part 13 formed in the body part 11 and having a predetermined space.

The protruding portion 12 may include a first protruding portion 12a and a second protruding portion 12b so that the cutting portion 13 is also inclined with respect to the longitudinal direction of the body portion 11, (The first inclined surface 14a and the second inclined surface 14b).

The reason for this is that, when cutting the surface of the member 10 for insertion, the cutting member has been cut by setting the cutting angle in two steps. Specifically, since the first cutting angle? 'And the second cutting angle? "Are different from each other, the slopes of the first slanted face 14a and the second slanted face 14b are different from each other, 12a and the second protrusions 12b are also formed differently.

On the other hand, the factors such as the secondary cutting length a, the primary cutting angle? ', The secondary cutting angle?' And the total cutting depth c can be set to a shape desired by the user .

At this time, it is preferable that the above-mentioned second cutting length a is 0.6 mm to 0.8 mm, and the total cutting depth c is about 0.18 to 0.25 mm. The diameter d of the body portion is preferably about 0.4 mm to 0.6 mm. Preferably, the first cutting angle b 'and the second cutting angle b' and the second cutting angle? 'Are about 25 ° to 40 °, and the first inclined surface has a larger inclination angle than the second inclined surface . This is because it is possible to extend and maintain the tissue more effectively when the member 10 for biometrics exists within the above-mentioned numerical range.

3 to 5, it can be seen that one or more protrusions 12 are formed at regular intervals along the longitudinal direction of the body part 11. FIG.

That is, the protrusions 12 are formed in a spiral shape (i.e., spirally) along the longitudinal direction of the body part 11 at regular intervals. For example, it is noted that one or more protrusions 12 may be formed at intervals of 180 degrees or at intervals of 90 degrees.

The density and the number of the protrusions 12 existing in the same length of the biopsy member 10 differ depending on the positions of the protrusions 12. The distance between the protrusions 12 It should be noted that the body insertion member 10 can be variously set depending on the state in which it is used.

The protrusions 12 may extend in opposite directions about a specific reference point M of the body 11. [ Note that the reference point M may be an intermediate point of the member 100 for biometrics according to the needs of the user and may be located at the distal end of the member 100 for biometrics.

For example, when the reference point M is located at the distal end, the biometrics member 100 may be provided with a protrusion protruding in one direction and only in the distal portion thereof. In this case, when a predetermined time has elapsed in a state where the body-insertable member 100 is inserted into the body, a spiral protrusion is formed only in one direction, and the body is moved along the groove to prevent protrusion from the nose tip or the skin . ≪ / RTI >

As described above, the biomechanical member 10 according to the present invention is not limited to the shape of the protrusion 12 (that is, the thickness, the length and the angle of the wing and the groove) In accordance with the intention of the user.

That is, due to such a configuration, when the biomechanical member 10 is inserted into a living body and the biomechanical structure is extended by applying a force, the tissue is stretched without much resistance. When the force applied to the living tissue is removed, The structure of the cutting portion 12 and the cutting portion 13 resists the force for returning the biomechanical tissue to its original state, so that the state of the tissue can be maintained continuously for a long period of time.

Therefore, it can be effectively used for extending and maintaining the soft tissue in the cosmetic surgery or cosmetic molding. Especially, since the thickness and the length of the protrusions and grooves are constant, the effect of the procedure is satisfactory when the nose is applied. do.

In addition, both ends of the member 10 for biometrical insertion according to the present invention are divided into one or more strands so as to prevent the member 10 for biometrical insertion in the living body from protruding outward.

Specifically, both ends of the body portion 11 may include divided portions 15a and 15b which are divided into at least one of four strands, six strands, and eight strands.

6, the divided portions 15a and 15b are divided by AA 'line, BB' line, CC 'line and DD' line by a wire or a cutting knife (not shown) , Six strands, and eight strands.

At this time, the divided portions 15a and 15b are preferably divided into a length of 0.3 mm to 0.7 mm in the longitudinal direction of the body portion 11, and are divided. The reason for this is that if the length is shorter than the length, the dividing portions 15a and 15b can not sufficiently perform the function, and if the length is longer than the length, it protrudes more than necessary and hinders the operation.

Due to the constitution including the divided portions 15a and 15b, the member 10 for biometrical insertion according to the present invention increases the surface area in contact with the living tissue at both ends to improve the tissue adherence, The pressure applied to both ends of the body 10 can be reduced to prevent the biopsy member 10 from protruding out of the skin (outside).

The dividing sections 15a and 15b can be formed naturally in the process of cutting for use of the biopsy member 10 or can be formed in advance in the process of manufacturing the biopsy- .

On the other hand, the biopsy member 100 may be constructed 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 biopsy member 100 is preferably made of a silicone material. The reason for this is that silicone material is widely used for medical use and particularly since the flexibility and the supporting force are better than the suture material described above and the biopsy member 100 is inserted into the living body, to be.
