    TECHNICAL FIELD
    [001] The present invention relates to a suture used for a surgical operation, and more particularly, to a suture that does not require a knot tying the operation and is capable of being firmly and stably sutured or to firmly support and repair tissues . PRIOR TECHNIQUE
    [002] A suture has been used for a long time to be used to connect and suture muscles, blood vessels, nerves or tissues and injuries or damaged parts cut due to a surgical operation. Additionally, a suture is used for a double eyelid surgery and a medical operation to remove tissue, which is generated due to age, a decrease in skin elasticity, lesions, overdose, necrosis, or the like, saggy skin, wrinkles or the like. A medical facelift operation using a suture is a technology to lift loose skin or tissue, such as a face, chin, neck, abdomen, vagina, breast or hip using needles and threads instead of using a scalpel. The medical facelift operation using a suture has attracted a lot of attention because the medical facelift operation does not excessively cut the skin, minimizes scarring, and generates less bleeding and swelling due to an operation.
    [003] Recently, the suture in which filaments are formed on an outer surface thereof has been developed and used. Such a suture does not slip due to the filaments, and thus the suture is not easily untied after the suture.
    [004] One of the stitches to be considered in an operation using a suture that is firmly held and fixed in a part where a surgical operation has been performed, in order to maintain stable suture and firm adhesion, supporting and securing the tissues. Additionally, a firm spinning device to allow a suture to not be loosened is necessary, and it is also necessary to minimize time and effort in the tying process for quick and safe operation.
    [005] The inventors of the present invention have filed Korean patent applications n° 10-2011-0019895 and 10-2011-0064084 for a suture including a suture holder not requiring a binding process, and the contents of these are introduced in the this descriptive report. The inventors of the present invention conducted the study in order to invent a more useful and convenient suture. DESCRIPTION OF THE INVENTION TECHNICAL PROBLEM

    [020] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in many different forms, and should not be construed as being limited to the embodiments set forth herein; rather, these realizations are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to a person skilled in the art. In the drawings, the parts of the needle, suture holder and filament are enlarged for clarity.
    [021] FIG. 1 is a view showing a suture holder 20 in accordance with an embodiment of the present invention. Suture holder 20 has a truncated conical shape or a truncated pyramid shape. The suture holder 20 includes a communication hole 25 through which the upper and lower end portions communicate with each other, and a diameter of the communication hole 25 is greater than that of a suture (see FIG. 1(A)).
    [022] The suture holder 20 according to an embodiment of the present invention may include one or more cut portions 23 that are cut in a longitudinal direction from a lower end portion 22 of the lower portion having a relatively larger diameter between the upper end portions and lower (see FIG. 1(B)). Alternatively, a portion of the bottom is removed so as to form one or more gaps 24 formed from the bottom end in a wall of the bottom end (see FIGS. 1(C) and 1(D)). A length of the cut part 23 and a size or shape of the gap 24 can be appropriately adjusted according to the parts and purposes for using a suture.
    [023] The suture holder 20 according to an embodiment of the present invention may be formed from a material not absorbed into a body or an absorbable material according to the purposes. For example, suture holder 20 can be formed from nylon, polypropylene (eg, MESH), polyvinylidene fluoride, polyester, stainless steel, gold, titanium, silicone, medpor, gore-tex, mesh, polylactic acid, polydioxanone ( PDO, PDS), or copolymer of lactic acid and glycolic acid, but the present invention is not limited thereto. If the suture holder 20 is formed of an absorbable material, it is not necessary to remove the suture holder 20 after suturing an internal part of the body.
    [024] The length of the suture holder 20 according to an embodiment of the present invention can be, for example, about 1 to about 10 mm. However, the present invention is not limited thereto, and thus the length of the suture holder 20 can be adjusted according to the parts and purposes for using the suture holder 20. Between the holes of both end parts of the holder of suture 20, a relatively smaller hole diameter, for example, about 0.1 to about 2 mm, and a relatively larger hole diameter, for example, about 0.5 to 5 mm. However, the present invention is not limited thereto, and hole diameters can be adjusted according to the thickness of a suture and suture usage purposes.
    [025] According to an embodiment of the present invention, when the suture holder 20 has a truncated conical shape or a truncated pyramid shape and includes the communication hole 25 and when a suture has first and second ends, the suture holder 20 it is connected to the first end, and the suture may have filaments. The suture holder 20 may include one or more cut portions 23 that are cut in a longitudinal direction from a lower end portion 22 of the lower portion having a relatively larger diameter between the upper and lower end portions (see FIG. 1(B)) , or a bottom portion is removed so as to form one or more gaps 24 formed from the bottom end in a bottom end wall 22 (see FIGS. 1(C) and 1(D)).
    [026] The method includes a step of coupling the suture to the suture holder 20 through the communication hole 25 so that an upper end portion 21 of the upper end having a relatively smaller diameter between both the upper and lower ends of the suture holder 20 faces the first end 11, and a step of forming a knot 50, which has a diameter greater than that of a hole in the upper end portion 21 of the suture holder 20, between the first end 11 of the suture and the upper end portion. 21 of the suture holder 20 and forming an agglomerated portion of the suture by applying heat thereto so that the suture holder 20 is not separated from the suture. However, the present invention is not limited to this.
    [027] According to an embodiment of the present invention, in the suture of the present invention, the other end part not connected to the suture holder 20, i.e., the second end 12, can be used in a coupled or uncoupled state to a needle . Here, the needle used is manufactured from a non-absorbable material such as a metal material, or an absorbable material (eg polylactic acid). The needle for a suture can be formed in the shape of a straight line or a curve, and a needle stitch can have a shape that is widely used, such as a round shape, a cut shape, or an extended shape.
    [028] Examples of a method of attaching a suture to a needle may include a method of inserting the suture into a hollow needle body and pressing the needle, a method of forming a hole (eye of the needle) in the needle and inserting the needle. suture in the hole, and the like. However, the present invention is not limited thereto, and several other methods can be used.
    [029] FIG. 2 is a view showing the suture including the first and second ends 11 and 12. In the suture, the suture holder 20 has a truncated conical shape or a truncated pyramid shape and includes the communication hole 25 through which the upper end portions and lower communicate. The suture holder 20 having cut-off portions or gaps in the lower end thereof is disposed at the first end 11 so that an upper end portion of the suture holder 20 (the upper end portion 21 having a relatively smaller diameter between the upper end and The lower end 21 and 22) faces the first end 11 of the suture connected to the suture holder 20, and a needle 30 is disposed at the second end.
    [030] The filaments are formed on a suture surface so that the angles between a longitudinal axis of the suture and the filaments are inclined in the same direction. The filaments are formed on the surface of the suture to be inclined so that an angle θ formed by the longitudinal axis of the suture and the filaments disposed at the second end of the suture is an acute angle. In this way, if the filaments are formed such that the angle between the filaments and the suture has a pointed shape towards the second end of the suture not including suture holder 20, the suture may lightly pass through the tissue when performing a suture using the needle attached to the second end of the suture. However, even if the needle is removed from the second end of the suture after suturing, if the suture intends to move in a direction opposite to a suture direction, the filaments can serve as a support to prevent suture movement. Although the needle is cut after suturing, the suture is not pulled out, so it is not necessary to tie a knot. Additionally, the suture holder 20 disposed at one end of the suture can serve as a knot that allows the suture not to be untied and can securely fix the suture holder 20 so that the suture holder 20 does not move due to the parts. cuts or gaps formed in the underside of the suture holder 20 when pulling the suture when performing a suture or lifting. In this way, the suture holder 20 can maintain a stable lifting effect for a long time.
    [031] According to an embodiment of the present invention, one or more sutures including filaments can be used, and a number of sutures can be appropriately adjusted according to the thickness of the sutures or purposes of use of the sutures. Each suture can be a single suture or a multiple suture that is twisted or woven. Here, the first end of each suture including filaments can be coupled to a suture holder 20 (see FIGS. 2(B), 2(C), 2(E) and 2(F)), or alternatively, the first end of each suture may include a separate suture holder (see FIG. 2(D)). Additionally, the second ends of the two sutures can be attached to one needle (see FIGS. 2(B), 2(C), 2(D) and 2(E)), or alternatively, different needles can be attached to the second of the two sutures, respectively (see FIG. 2(F)).
    [032] FIG. 2(B) shows two or more sutures in which the front filaments and rear filaments are formed to be bent in the same direction. In FIG. 2(B), the end parts of the suture are attached to a needle and the other end part of the needle is attached to the suture holder 20. Here, the filaments are arranged to be inclined so that the angle θ formed by the longitudinal axis of the suture and the filaments disposed at the end of the suture coupled to the needle is at an acute angle. FIG. 2(C) shows another embodiment in which one or more sutures are folded in half and then both ends are coupled to the suture holder 20 and the needle. In FIG. 2(C), the suture is formed so that the front filaments and rear filaments formed in the suture are slanted in an opposite direction (eg, so that an angle between the front filaments and the longitudinal axis of the suture is less than 90° and the front filaments are slanted towards a front end of the suture and such that an angle between the rear filaments and the longitudinal axis of the suture is less than less than 90° and the rear filaments are slanted towards the rear end of the suture).
    [033] FIG. 3 shows a suture to which the suture holder 20 is attached, which includes a communication hole through which the upper and lower end portions communicate and has a truncated conical shape or a truncated pyramid shape, or the suture holder 20 is coupling that includes a communication hole through which the upper and lower end portions communicate, has a truncated conical shape or a truncated pyramid shape, and has cut portions or gaps in a lower end portion of the suture holder 20. The holder of suture 20 is coupled to the suture through the communication hole to be disposed at the first end 11 so that the upper end portion 21 (end portion having a relatively smaller diameter than the upper and lower end portions) of the suture holder 20 faces the first end 11 of the suture, and the needle is not disposed at the second end 12. The suture may include filaments on the surface thereof, and the filaments may be formed to be inclined towards the second end of the suture so that an angle θ formed by the longitudinal axis of the suture and the filaments are an acute angle.
    [034] According to an embodiment of the present invention, one or more sutures including filaments can be used, and a number of sutures can be appropriately adjusted according to the thickness of the sutures or purposes of use of the sutures. When two or more sutures are used, the sutures may pass through a communication hole of a suture holder 20 to make a knot (see FIGS. 3(B) and 3(C)), or alternatively, a suture is attached to the suture holder 20 to pass through the communication hole of the suture holder 20 (see FIG. 3(D)). FIGS. 3(C), 3(D) and 3(E) show an example in which one or more sutures, which are formed such that the front filaments and back filaments are slanted in an opposite direction, are folded in half and then one end of the suture is attached to the suture holder 20.
    [035] A suture including filaments is disclosed in Korean Patent Application No. 10-2008-0039345 and 10-2005-0108494, Korean Utility Model No. 20-320005, US Patent No. 5931855, and the like, and the contents are introduced in this descriptive report. The filaments can be arranged in a fiber according to any necessary configurations, and can be formed using any suitable methods including methods well known in the art. These methods can include injection molding using a knife, a laser, or pressure molding, stamping and cutting. A required number of pieces cut at an acute angle are formed into a suture. A filament size can be appropriately adjusted for purposes within the limits of common sense in the art. For example, a depth of the filament formed in the suture can be about 30 to 100 microns and can be adjusted according to a diameter of the suture. A gap between filaments formed on a suture surface can be about 100 microns and 1 mm or more.
    [036] The suture used in the present invention can be formed, for example, of a polymeric material, a metallic material, a biological material, or the like. The suture can be formed from a non-absorbable material, for example, polypropylene, gold, stainless steel, titanium, nylon, polyvinylidene fluoride, polyester, or woven silk, or an absorbable material, for example, polydioxanone (PDO, PDS). However, the present invention is not limited to this. Additionally, the suture used in the present invention can be formed into a shorter wound shape or a twisted shape.
    [037] Here, the description will be of a method of using a suture 10 including the suture holder 20 at one end thereof, wherein the suture holder 20 may include a communication hole through which the upper and lower end portions communicate and have a truncated conical shape or a truncated pyramid shape, or may include cut off portions or gaps in a lower end of the pyramid and have a truncated cone shape or a truncated pyramid shape. The method can include the following processes. 1) a step of piercing the skin or tissue using a needle such that a suture holder is placed in a predetermined position of the skin or tissue and pushing a hollow tube into the predetermined position of the skin or tissue, 2) a a step of inserting the suture 10 including the suture holder 20 according to an embodiment of the present invention into the barrel such that the suture holder 20 reaches the predetermined position, 3) a step of pressing the suture holder 20 having passed through of the pipe into the skin or tissue from the outside, securing the suture holder 20 using a thin bar in order to move and remove only the pipe, and 4) a step of pushing the skin or tissue by pressing the holder. suture 20 and pull the suture. Here, one or a plurality of sutures can be used in which a row of filaments is formed and includes suture holder 20 at one end thereof. Alternatively, the suture used here can be a suture in which two or more strands of filaments are formed can be coupled to a suture holder 20. In the method described above, the suture holder 20 can serve as a knot that allows for suturing. that the suture is not untied and can also allow the suture not to move and be secured by pulling the suture when performing a suture or lift. The suture holder 20 having the cut parts or the gaps formed at the lower end thereof can still firmly secure the suture, and thus the suture holder 20 can keep a stable lifting effect for a long time.
    [038] When the filaments are formed to be inclined towards the second end such that the angle θ formed by the longitudinal axis of the suture and the filaments disposed at the second end of the suture is an acute angle, the filaments formed can prevent the suture from be pulled out in a direction opposite to elevation by an angle between the filaments and a surface of the suture and can maintain tissue in a pulled state. When inserting the suture into a long pipe, the resistance against the tissue does not exist, so the suture can easily pass through the long pipe. Additionally, even when removing the long barrel and pushing the tissue by pressing the suture holder 20 and pulling the suture, the filaments formed so that an angle between the filaments and the suture is an acute angle does not greatly affect tissue movement, but if the fabric intends to return in an opposite direction, the filaments resist.
    [039] An embodiment of the present invention provides a device capable of easily performing an operation using the suture provided in the present invention. The device provided in the present invention includes a kit (kit A) equipped with a suture and a suture positioning kit (kit B) to allow a suture to be precisely positioned in tissue.
    [040] The kit (kit A) equipped with a suture includes a hollow tube 70 in which a hole through which both end parts communicate with each other is formed, and the suture installed in the hollow tube 70. The suture has the first and second ends, and suture holder 20 is disposed at the first end of the suture. The suture holder 20 may have a truncated conical shape or a truncated pyramid shape and may include a communication hole through which the upper and lower end portions communicate with each other. Alternatively, the suture holder 20 may have a truncated conical shape or a truncated pyramid shape, it may have a communication hole through which the upper and lower end portions communicate with each other, and cut portions or gaps may be formed in the portion. lower end of this. The suture holder 20 is coupled to the suture through the communication hole to be disposed at the first end of the suture so that the upper end of the suture holder 20 faces the first end of the suture. The suture may include filaments on a surface thereof, and the filaments may be formed to be inclined towards the second end of the suture such that an angle θ formed by the longitudinal axis of the suture and the filaments disposed at the second end of the suture is an angle acute. In kit A, the suture holder 20 provided in the present invention is disposed in the hollow barrel 70 in which both end parts communicate with each other, and a suture including filaments on a surface thereof is inserted into the hollow barrel 70. Here, the holder of suture 20 is positioned at one end of the suture pierced in a tissue between both ends of the suture (see FIG. 4(A)). The suture holder 20 can be positioned inside the hollow tube 70 or outside the end of the hollow tube 70, or it can be positioned through the inside and outside of the hollow tube 70, when necessary. In kit A, the hollow pipe communication hole 70 can have a diameter capable of accommodating the suture, and the diameter can be adjusted for the purposes.
    [041] The suture positioning kit (kit B) to allow a suture to be precisely positioned in a tissue includes a hollow tube 80 in which a communication hole through which both end parts communicate with each other is formed, and a rod 90 which is inserted into the communicating hole of the hollow barrel 80, is shaped to be longer than the hollow barrel 80, and has a pointed tip capable of being inserted into a body on one side thereof (see FIG. 4(B) ). Stem 90 is formed of a material having the strength to be pierced into skin or tissue, and if the pointed tip of stem 90 has a blind or rounded shape, tissue damage can be minimized.
    [042] Hollow barrel 80 from kit B is shorter than hollow barrel 70 from kit A, and may have a larger communication hole diameter than kit A to accommodate kit A. rod can be formed from any material that has high rigidity to be pierced into a metal or tissue and is harmless to humans, eg urethane or plastic. The hollow barrel 70 from kit A and the hollow barrel 80 from kit B can be provided with a handle on one end of the latter for convenient operation.
    [043] The device shown in FIG. 4 can be used using a method including the following processes. 1) one step of pushing kit B into a part or tissue to be sutured or lifted, 2) one step of removing only stem 90 and leaving hollow barrel 80, 3) one step of pushing kit A into hollow barrel 80 remaining in a tissue (here, a part where the suture holder 20 is positioned is allowed to face the inside of the tissue), 4) a step of removing the hollow barrel 80 from kit B and leaving kit A in the tissue. 5) one step of pushing the suture holder 20 using a thin bar on the outside of the fabric of the hollow barrel 70 from kit A, 6) one step of removing the hollow barrel 70 from kit A and the thin bar, and 7 ) one step pushing the skin (or the outside of the tissue) towards the suture holder 20 when pulling a suture. If necessary, it is possible to allow the suture holder 20 not to move by pushing the suture holder 20 from the outside (eg the skin).
    [044] The present invention also provides a kit that facilitates an operation using the suture provided in the present invention (see FIG. 5). The kit includes: i) a hollow barrel 104 including a front end provided with a point 101 which is shaped to be tapered, a rear end provided with a loop 103, and an accommodation part 102 accommodating the suture holder 20 disposed in a suture around the front end capable of being separated in one direction of a longitudinal axis connecting the front end and the rear end; and ii) the suture including suture holder 20 which is installed in the hollow barrel 104 and is provided in the present invention. FIG. 5(A) shows the hollow barrel 104 in which the suture including suture holder 20 is disposed.
    [045] Here, one end of the front end of the hollow barrel 104 can be closed, or alternatively, a hole can be formed in the front end of the hollow barrel 104 to communicate with the rear end. The tip may be formed from a material having the strength to pierce a tissue. If the tip is formed to be rounded, tissue damage can be reduced. The accommodation portion 102 formed in the hollow barrel 104 is formed to extend from the front end portion and is a space capable of accommodating the suture holder 20 disposed in the suture. A size and shape of the accommodation part 102 can be appropriately adjusted in accordance with a size and number of the suture holder 20 accommodated in the accommodation part 102 (see FIGS. 5(B)).
    [046] The hollow barrel 104 can be separated in one direction along a longitudinal axis connecting the front end and the rear end as shown in FIG. 5C. Hollow barrel 104 can be formed by placing the suture including suture holder 20 over half 104b of separate hollow barrel 104 and covering the other half 104a over the suture. Here, for example, a convex part 105 can be formed in a half loop 103a and a half loop 103b at the junction of the half loop 103a and the half loop 103b, and a concave part 106 can be formed in the other half loop 103a and the half loop 103b at the junction of half loop 103a and half loop 103b so that half loop 103a and half loop 103b can be stably attached by coupling half loop 103a and half loop 103b to each other, thus keeping the hollow barrel stable. 104 accommodating the suture (see FIG. 5(D) which is a top view of loop 103). Additionally, various methods can be carried out to allow the hollow barrel 104 formed by coupling the two separate parts together to maintain its shape stable up to a time required during an operation.
    [047] An operation can also be performed using a method of pushing the hollow barrel 104 accommodating the suture in a part to be sutured or raised from the tip 101, inserting the thin bar through a space of the hollow barrel 104 in order to move the suture holder 20, separating the hollow barrel 104 to sequentially remove the separate half parts 104a and 104b, and pushing the skin (or outer tissue) towards the suture holder 20 by pulling the suture.
    [048] The suture provided in the present invention can be used to safely perform an operation without making a knot by adhering, supporting and firmly fixing the tissues to be sutured. The suture can be held and fixed firmly on a part to be sutured and can hold the tissues effectively. Additionally, when the kit provided in the present invention is used, an operation can be easily, simply and effectively performed irrespective of the skill of a physician. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail can be made without departing from the spirit and scope of the present invention as defined by the following claims.
