In the case of experimental animals, especially rabbits, mice, rabbits, and beagles, where the movement of muscles is frequent, especially when the implantation material such as fat is injected into the mouth, neck, and limbs, the implanted area is severely moved. Irregularly received, the implant spreads or spreads outwards.

Even during the healing period, strong tension may occur in the direction of normal healing and fibrosis may be excessively proliferated, and bleeding may be caused, causing unexpected side effects, hematoma, and calcification.

In such experimental animals, there is a method of elastically fixing living tissue around the implant to prevent the spread of the implant broadly or outward. Specifically, a method of elastically fixing tissues outside a living tissue or elastically fixing the tissues inside a living tissue is known.

As a method of elastic fixing from the outside in the double, it can be made by using an external gamet or splint, cast, tape fixing, and the like. However, this method has a problem in that the fixing force is weak and it is difficult to limit the desired area.

In addition, the method of elastic fixation in the inside can be fixed to the surrounding tissue using a suture in the incision state, but the experiment time is long and may cause unexpected reaction during the healing process of the wound after the incision. There are many problems such as bacteria can penetrate inside. In addition, there is a problem that it is difficult to find a specific fixed position in the case of the neck and proximal limbs at the time of incision.

Hereinafter, an elastic fixing method of a living tissue according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The elastic fixation method of a living tissue of the present invention is inserted into a living skin (S) of an animal to perform elastic fixing between the first fixed tissue site (A1) and the second fixed tissue site (A2) in the living skin (S). It is an elastic fixation method of biological tissue. This elastic fixing method, after inserting the suture 20 inserted into the needle 10 through a small incision of the living skin (S), therein the first fixed tissue site (A1) and the second fixed tissue therein The parts A2 are elastically fixed to each other.

At this time, the first fixed tissue portion (A1) may be anywhere that the surgery is required, especially when the implant (C) is to be inserted into the surrounding tissue portion of the implant (C).

In addition, the second fixed tissue site (A2) is preferably an area opposite to the first fixed tissue site (A1) with the implant (C) therebetween, but is not limited to the first fixed tissue site Of course, any tissue in the skin that needs to be elastically fixed with A1 can be used. On the other hand, the first fixed tissue portion (A1) may be a local portion and may be a somewhat wider portion, if necessary, as is the second fixed tissue portion (A2).

This elastic fixing method, the first step of inserting the needle 10 is inserted into the interior of the skin of the living body suture 20, the adhesion projection 21 is formed on the surface, and the insertion of the needle 10 A second step of inserting the needle 10 such that an end thereof is positioned up to the first fixed tissue site A1 in the skin of the living body and adhering the end of the suture 20 to the first fixed tissue site A1; The first suture 20, the end of which is bonded in the form of a zigzag extending in a direction substantially parallel to the insertion direction of the needle 10 in the first fixed tissue site (A1) A third step of reciprocating the needle 10 to be adhered to A1), and moving the needle 10 to the second fixed tissue site A2 so that the suture is adhered to the second fixed tissue site The fourth step is to make it possible.

Specifically, as shown in FIG. 2 (a), after the needle 10 is inserted into the desired first fixed tissue site A1, the end of the suture 20 is first fixed tissue site A1. 2 and the suture 20 inside the needle 10 is pushed out while retracting the needle 10 to a predetermined range as shown in FIG. On the other hand, thereafter, as shown in Fig. 2 (c), while inserting the needle 10 again while moving the needle 10 in a direction substantially horizontal to the insertion direction, and moves the needle in an approximately inclined direction Accordingly, the suture 20 is fixed in the biological tissue in the form of approximately "V".

Subsequently, as shown in FIGS. 2D and 2E, the suture 20 is zigzag in a zigzag manner by repeating the above-described steps to incline the needle 10. To be able to coalesce within.

On the other hand, after securing a sufficient fixing force in the first fixed tissue site (A1), as shown in Figure 2 (f) retracts the needle 10 to the second fixed tissue site (A2) while retracting the needle ( 20) can be coalesced.

When the suture 20 is adhered to the living tissue by the above method, the suture 20 can be reliably fixed to the first fixed tissue site A1, thereby ensuring a firm fixation force, and thus the movement Even when the implant is inserted in many of these areas, there is an advantage that the damage of the implant can be reliably prevented.

As shown in Figure 1 is fixed in the biological tissue by this method, in Figure 1 by using the above-described elastic fixing method to fix the first fixed tissue portion (A1) in a zigzag and the other suture 2 to be fixed in a fixed tissue region (A2) zigzag.

On the other hand, in the third step it is preferable that the needle can be reciprocated at least three times or more to provide a firm fixing force so that the suture is firmly adhered to the fixed tissue site.

In addition, a single suture may be inserted into the needle, but is not limited thereto, and two or more sutures may be inserted into one needle as shown in FIG. 3. As such, when a plurality of sutures are inserted into a single needle, there is an advantage of providing a more secure fixing force as shown in FIG. 4. In particular, two or more sutures have the advantage of not being able to easily recognize that the suture is inserted in the skin tissue when viewed from the outside by thinning the overall thickness rather than thickening a single suture.

The adhesion protrusion 21 is also to enhance the adhesion to the biological tissues of the human body, it is also preferred to have the effect of being fixed to the tissue only in one direction by placing the orientation. Such suture 20, but it is also possible to use a single suture, but more preferably two or more are used for a more secure fixing force.

On the other hand, the directionality of the coalescing protrusions 21 may not only have the directionality in one direction but also have the directionality in both directions. For example, it is possible to change a variety of designs according to the treatment conditions, such as one direction in one section and another direction in another section.

These sutures 20 can be used in a variety of materials to maximize the adhesion to the human tissue and excellent elasticity and strong support, 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, Titanium (Ti) and Titanium Materials such as alloys can be used.

The handpiece 30 is detachably coupled to the other end 10b of the tubular needle 10, the suture 20 is inserted therein, and the suture 20 to the outside through the needle 10. It is an auxiliary device for pushing the suture, in which the pushing member 32 is pushed out.

This handpiece 30 includes a body portion 31 and the pushing member (32). The body portion 31 is formed integrally with the entry portion 311 and the entry portion 311 having a shape corresponding to an end portion of the needle 10 so as to be inserted into the end portion of the needle 10. It consists of a support part 312 for supporting the roller 321. The support 312 is formed with a support plate 313 rotatably pivotally coupled. The support part 312 and the support plate 313 are connected by the elastic spring 314, which allows the support plate 313 to always be placed in a constant position with respect to the support 312. . On the other hand, the entry portion 311 is formed with a slot 311a in a direction perpendicular to the longitudinal direction of the suture 20, the suture 20 is perpendicular to the longitudinal direction of the suture 20 in the slot 311a. It can be inserted in the direction.

The pushing member 32 is installed side by side facing each other with the suture 20 interposed therebetween and pushes the suture 20 from the needle 10 as it rotates in contact with the suture 20. It consists of a pair of rollers 321.

On the other hand, at this time, the roller 321 disposed on the upper side of the pair of rollers 321 is rotatably coupled to the support portion, the lower roller 321 is rotatably coupled to the support plate 313. At this time, since the lower roller 321 is coupled to the support plate 313 that is elastically rotated with respect to the support 312, the lower roller 321 may be elastically biased toward the upper roller 321.

In the tubular needle package according to the preferred embodiment of the present invention, the support plate 313 is rotated as shown in FIG. 6 in a state where the suture 20 is inserted into the slot 311a and coupled to the body portion 31. The lower roller 321 is to face the upper roller 321 so that the suture 20 can be disposed between the pair of rollers 321. After that, the other end of the needle 10 is coupled to the body portion 31 side. Thereafter, as shown in FIG. 7, the suture 20 is pushed into the needle 10 while rotating the upper roller 321. At this time, the suture 20 can be easily pushed out by the surface friction of the rollers (321). In the present embodiment, the upper roller 321 is rotated by a finger, but the present invention is not limited thereto, and various driving means, for example, a motor, may be used.

In this embodiment, the suture is moved upward by using a roller, but is not limited thereto, as shown in FIGS. 8 and 9.

It is also possible to use the slide means 323. For example, the tubular needle package according to another embodiment of the present invention consists of a needle 10, a suture 20, and a handpiece 30. At this time, the handpiece 30 is composed of a body portion 31 and the pushing member (32). The shape of the body portion 31 is similar to that shown in FIGS. 6 and 7. However, the extrusion member 32 is extended along the longitudinal direction of the suture 20, the sliding surface 322 on which the suture 20 can be seated, and the sliding surface with the suture 20 therebetween. It is disposed on the opposite side of the 322 is coupled to the body portion 31 to move along the longitudinal direction of the suture 20 and moves in contact with the suture 20 seated on the sliding surface (322) 20 may include slide means 323 to push the needle 10 out of the needle 10.

At this time, the slide means 323 is slidably coupled by an elastic line 324 installed on the body portion 31 so as to be elastically biased toward the sliding surface 322. On the other hand, it is preferable that the uneven surface is formed on the surface in contact with the suture 20 in the slide means 323, so that the suture 20 can be easily moved along the slide means (323).

The tubular needle package shown in FIG. 8 is pressed by pressing the slide means 323 somewhat spaced apart from the suture 20 seated on the sliding surface 322, and the slide means 323 and the suture 20. In this case, as shown in FIG. 9, when the slide means 323 moves forward, the suture 20 moves forward with the slide means 323. Meanwhile, in the technique of FIG. 6, the support plate 313 is rotatably supported by the elastic spring 314 in a state in which the support plate 313 is pivotally coupled to the support part 312, but in this embodiment, the support plate 313 is a ratchet ( By 312a). In addition, the sliding surface 322 means the upper surface of the support plate 313.

On the other hand, as shown in Figure 10, one end (10a) of the tubular needle (10) is preferably formed in a blunt cross-sectional shape in order to reduce the frictional force generated in the contact surface during the suture pushed out.

The tubular needle package according to another embodiment of the present invention may be modified as shown in FIGS. 11 to 14.

FIG. 11 is a perspective view of the tubular needle package, FIG. 12 is a side cross-sectional view of FIG. 11, FIGS. 13 and 14 are views of the main components, and FIG. 15 is an operational view of FIG. 11. The handpiece 30 of the tubular needle package consists of a body portion 33 and a pushing member 34. The body part 33 includes a main body 331 having a guide slot 331a extending in one direction and a bar member 332 rotatably installed with respect to the main body 331.

The pushing member 34 is mounted on the guide slot 331a of the main body 331 to slide the slide portion 341, the wave is mounted on the upper side of the slide portion 341, the user's hand wave A branch portion 341a, an entry portion 342 connected to the slide portion 341 and having a shape corresponding to an end portion of the tubular needle so as to be inserted into an end portion of the tubular needle, and coupled to the entry portion 342. A guide portion 343 for guiding the suture, a driven roller 347 rotating while being in contact with the slide portion 341, and rotatable by receiving a rotational force of the driven roller 347, and a suture is inserted therebetween. And extrusion rollers 345 and 346.

The driven roller 347 is rotatably coupled to the main body 331, one of the push rollers 345 is rotatably coupled to the main body 331 and the other push roller 346 is It is rotatably coupled to the bar member 332.

On the other hand, the push roller 345 is provided with a one-way gear for receiving the rotational force of the driven roller 347 to rotate the push roller 345 only when the driven roller 347 rotates in one direction. Therefore, when the driven roller 347 is rotated in the other direction, the push roller 345 will be idle. Specifically, the one-way gear is composed of protrusions 345a installed in the extrusion roller in the circumferential direction, and a locking gear 345b caught in one direction by the protrusions 345a.

In the tubular needle package according to the present embodiment, when the slide unit moves, the driven roller coupled to the slide unit rotates the push roller, and accordingly, the suture in contact with the push roller is pushed. In addition, the entrance coupled to the needle moves forward while the needle moves forward. On the other hand, when the slide unit is retracted, the driven roller rotates, but by the one-way gear, the pushing roller does not rotate together with the driven roller, but instead turns away. On the other hand, at this time, the entry stock is retracted with the needle while retreating.

The tubular needle package according to the invention can be used as follows. That is, after inserting the needle into the living skin, the suture inside the needle is pulled out while the end of the suture is fixed to a desired area in the living skin, and the suture inside the needle exits the inside of the living skin. In the process of pushing the needle again, the push member is operated to allow the suture to be pushed out of the needle so that the suture is zigzag at a desired site. That is, in the process of the needle falling back, the suture naturally comes out of the needle, so it is not necessary to use a separate pushing member, but in the process of the needle coming out, the suture becomes difficult to come out in contact with the end of the needle. By using the pushing member, the suture can be easily pulled out of the needle.

In the above-described embodiment, the tubular needle package can be used in the treatment of animals and the like, but is not limited thereto and can be used for humans and can be used in various procedures such as wrinkle removal.

Although the present invention has been described in detail by way of examples, the present invention is not necessarily limited to these embodiments and modifications, and may be variously modified and implemented within the scope of the technical spirit of the present invention.
