Description

[0001] SUTURE THREAD [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a suture formed with a locking protrusion, and more particularly, to a suture which improves the effect of a procedure by forming a locking protrusion in a rotation direction.

In general, sutures used as surgical suture materials can be classified into synthetic sutures and natural sutures according to the raw materials, and absorbable sutures and sutures that are naturally decomposed after a certain period of time The non-absorbable suture can be classified as a non-absorbable suture that requires removal of the suture through reoperation because the tissue at the wound site is not degraded after suturing. According to other manufacturing methods, monofilament suture composed of one filament and multifilament suture made by braiding several filaments can be classified.

Such a suture is attached to one end of a suturing needle, and a structure in which a suture is inserted into one end of a typical suturing needle is disclosed in U.S. Patent No. 1,558,037. That is, one end of the suture thread is inserted and fixed to a cylindrical installation groove formed at one end of the suture needle.

It has been common to use a suture formed with a locking protrusion for fixation. However, the conventional suture has a problem that the effect of the procedure is lowered because the locking protrusion is formed only on the end face.

The present invention provides a suture that improves the effect of the procedure by forming a locking protrusion in the direction of rotation.

According to an embodiment of the present invention, the suture includes a body having a predetermined length and a first locking protrusion formed at one end of the body in the direction of the other end, and the first locking protrusion is formed continuously in the screw direction.

The suture may further include a second locking protrusion formed in the one end direction from the other end of the body.

The first locking protrusion of the suture and the second locking protrusion may be formed at an angle of 20 DEG to 25 DEG from the body.

The first locking protrusions of the suture thread may be formed while being rotated at intervals of 90 degrees along the screw direction.

The body of the suture may have a cross-sectional diameter of 0.20 to 0.60 mm.

The first locking protrusion of the suture and the second locking protrusion of the suture may be formed at intervals of 1 to 2 mm, respectively.

The suture may have a length ratio of 3 to 5: 5 to 7 between the portion where the first locking protrusion is formed and the portion where the second locking protrusion is formed in the body.

The body of the suture may include at least one of PDO (PDS), polyglycolide (PG), polylactide (PL), or polycaprolactone (PCL).

According to another embodiment of the present invention, a needle having a suture includes a handle provided at one side, an insertion portion connected to the handle to be inserted into the body, a body formed at a predetermined length, And a second latching protrusion formed at the other end of the body in the one end direction.

Wherein the first and second locking projections are formed at an angle of 20 ° to 25 ° with respect to the body, the first locking protrusions are formed while being rotated at intervals of 90 ° along the screw direction, The first locking protrusion and the second locking protrusion may be formed at intervals of 1 to 2 mm, respectively.

The needle having the suture has a length ratio of 3 to 5: 5 to 7 in a portion of the body where the first locking protrusion is formed and a portion in which the second locking protrusion is formed, and the body is made of PDO (Polydioxanone) , Polyglycolide (PG), polylactide (PL), or polycaprolactone (PCL).

The needle having the suture incorporated therein may be formed by bending the suture at one end of the insertion portion of the needle.

The needle having the suture incorporated therein may further include a fixing device for fixing the folded suture.

The length of the suture may be any one selected from 150 mm, 200 mm, 250 mm, 300 mm, 350 mm or 400 mm.

The suture according to the embodiment of the present invention has the effect of maximizing the lifting effect due to the procedure.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

The drawings are schematic and illustrate that they are not drawn to scale. The relative dimensions and ratios of the parts in the figures are shown exaggerated or reduced in size for clarity and convenience in the figures, and any dimensions are merely illustrative and not restrictive. And to the same structure, element or component appearing in more than one drawing, the same reference numerals are used to denote similar features.

The embodiments of the present invention specifically illustrate ideal embodiments of the present invention. As a result, various variations of the illustration are expected. Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture.

Hereinafter, a suture 100 according to the present invention will be described with reference to Figs.

1, the suture 100 according to the present invention includes a body having a predetermined length and a first locking protrusion formed at one end of the body in the other end direction, .

As shown in FIG. 2, the body 110 formed in a predetermined length may have a circular cross-section, but may be formed in various polygonal shapes such as a triangle, a rectangle, and a pentagon, .

The body may include at least one of PDO (PDS), polyglycolide (PG), polylactide (PL), or polycaprolactone (PCL). The materials are naturally decomposed after a certain period of time after being inserted into the object. PDO (PDS: Polydioxanone) has the advantage of maximizing the effect of the suture according to the embodiment of the present invention, which is a safe thread which received KFDA KFDA 4 grade which is the highest safety grade for the medical device.

The body 110 has a first locking protrusion 120 formed at one end of the body in the direction of the other end, and the first locking protrusion is formed continuously in the screwing direction. Conventional sutures were formed only on one end face in a specific direction. However, in the present invention, the first locking protrusion formed on one end face is characterized in that the first locking protrusion is formed while rotating in the screw (spiral) direction until the next first locking protrusion is formed on the same end face in a specific direction. That is, the first locking protrusion is formed by changing the position along the direction from the one end to the other end with respect to the body. In this case, the conventional suture locking mechanism compensates for weakness of the physical traction force, and it is inserted into the SMAS layer of the skin to hook up the tissue, thereby improving the physical traction force and obtaining an excellent lifting effect.

Specifically, the tissue changes caused by the suture according to the present invention are as follows. Insert the suture first. The inserted suture activates dendritic fibers and cells through tissue damage and increases growth factors. In addition, the collagen, elastin, and neovascularization of the suture is increased, and the fibrotic capsule around the suture forms the support gudxofh scaffold. These sutures cause a lifting effect, promote collagen regeneration and improve skin elasticity. In addition, the blood circulation is improved due to the increase of the new blood vessels, and the cellulite is decomposed to relax the muscle tension.

The first locking protrusion formed along the screw (helical) direction can appropriately adjust the number of the first locking protrusions while rotating one wheel. As shown in FIG. 2, the first locking protrusion may be formed in three directions while rotating one turn from one end to the other end of the body. In this case, the first locking protrusion may be formed at an angle of 120 ° when the gap is maintained to be the same, and the first locking protrusion may be formed by varying the angle by adjusting the angle as necessary. Also, the first locking protrusion may be formed in four directions while being rotated one turn from one end to the other end of the body. In this case, the first locking protrusion may be formed at an angle of 90 degrees, and the first locking protrusion may be formed by adjusting the angle to adjust the gap. Also, the first locking protrusion may be formed in five directions while being rotated one turn from one end to the other end of the body. In this case, the first locking protrusion may be formed at an angle of 72 °, and the first locking protrusion may be formed by adjusting the angle to adjust the gap. Although only three cases are illustrated in FIG. 2, a first locking protrusion may be formed by adjusting various directions and angles as necessary.

As a result, in the case of the first locking protrusion, when the body of the suture is cut in the direction normal to the longitudinal direction, the first locking protrusion is formed while rotating in the screw (helical) direction. And the first locking protrusion is formed in various cross-sectional directions.

The suture according to the present invention may further include a second locking protrusion 130 formed at the other end of the body in the one end direction to maximize the physical pulling effect of the first locking protrusion. In the case of the second locking protrusion, since the first locking protrusion is inserted into the object and then fixed, the lifting effect accompanied by the physical traction force is raised not only by lifting up the portion where the second locking protrusion is stretched, When the thread breaks down, the second cell transformation transforms the new collagen into a small, smooth line that is stretched and remodeled.

In the case of the first and second locking protrusions, it is preferable to adjust the angle with respect to the body in accordance with a desired effect. Generally, the angle is preferably 20 to 25 degrees from the body.

FIG. 2 is a view of the body viewed from one end to the other end, and its cross section is circular. However, as described above, it is possible to form various polygons according to need. The first locking protrusion shown in Fig. 2 is formed along the direction of the other end from one end to the other and has a first locking protrusion in various directions. However, when the locking protrusion is cut in the normal direction of the longitudinal direction of the body, Or more, is not formed. At this time, it is preferable that the diameter of the cross section is 0.20 to 0.60 mm.

The distance between the first and second locking protrusions formed on the suture according to the present invention can be appropriately adjusted, and it is generally 1 to 2 mm.

The suture according to the present invention can appropriately adjust the length ratio between the portion where the first locking protrusion is formed and the portion where the second locking protrusion is formed according to the purpose and method of the procedure, 5 to 7 is preferable.

3 is a needle having a suture incorporating a suture according to the present invention. This will be described below with reference to FIG.

The needle having the suture according to another embodiment of the present invention includes a handle 210 provided at one side, an insertion part 220 connected to the handle to be inserted into the body, a body formed with a predetermined length, And a second locking protrusion formed on the other end of the body in the direction of the one end. The first locking protrusion is formed continuously in the screw direction along the other end direction from the one end of the body.

The handle 210 allows a user to hold a needle having a suture built therein according to an embodiment of the present invention. The handle may include an elastic material to easily hold the needle when the needle with the suture is used, but it may be formed of various materials as needed.

The needle with the suture is a tool used to insert the suture into the object. The suture is inserted into the needle and the suture is inserted into the object through the needle. At this time, the suture included in the needle is the same as the suture described above, so that the explanation is omitted.

Wherein the first and second locking projections are formed at an angle of 20 ° to 25 ° with respect to the body, the first locking protrusions are formed while being rotated at intervals of 90 ° along the screw direction, The first locking protrusion and the second locking protrusion may be formed at intervals of 1 to 2 mm, respectively, in the same manner as the suture.

The needle having the suture has a length ratio of 3 to 5: 5 to 7 in a portion of the body where the first locking protrusion is formed and a portion in which the second locking protrusion is formed, and the body is made of PDO (Polydioxanone) It can be made of at least one of polyglycolide (PG), polylactide (PL), polycaprolactone (PCL), and the like.

In addition, the suture thread of the needle having the suture included therein may be formed by bending at one end of the insertion portion of the needle, and may further include a fixing device 230 for fixing the sutured suture. The suture is bent at one end of the insertion portion and extends in a direction toward the handle portion. At this time, the fixing device is pushed in the direction opposite to the direction in which the needle is inserted, so that the fixing device is not inserted into the object, and only the needle and the suture can be inserted into the object. In addition, the suture remains on the object even after the needle is retracted and removed.

The length of the suture may be any one selected from 150 mm, 200 mm, 250 mm, 300 mm, 350 mm or 400 mm. The length of the suture can be varied according to various conditions, and it is generally preferable to use any one of the lengths exemplified above.
