Description

Suture thread and method for producing same

Technical Field

The present invention relates to a suture thread applied to a surgical operation and a suturing method using the same, and more particularly, to a suture thread which does not require a knotting step in a suturing operation; a method of manufacturing the suture; and a suturing method using the suture thread.

Background

In suturing various surgical operations such as injured muscles, blood vessels, nerves, wound or surgical incisions, double-fold eyelid surgery, wrinkle plastic surgery, etc., tying knots to prevent the suture from loosening after the suture is sutured is a time-consuming, annoying and very important task that affects the outcome of the operation. In the sewing process, knots are used to prevent the loosening of the beginning and ending portions, or the middle section, if necessary, of the seam.

Since it is very important to shorten the operation time and to complete the operation as fast as possible, the suture and knot technique is indispensable for a stable and efficient operation. However, during a surgical procedure using, for example, a laparoscope (laproscope), an endoscope (endoscope), or an arthroscope (arthroscope), it is not easy to rapidly tie a knot at a distance using a tool to engage a suture portion of a body.

Traditionally, to tie a suture to a knot during suturing, operators use two tools to secure or wrap the suture while grasping it. Since large space is required for operating both tools, the operator must be experienced to minimize the time required for surgical suturing in as limited a space as possible, such as the abdominal cavity. Accordingly, a method and a suturing tool, for example, a tool having an excellent degree of freedom, such as a Cambridge endoscope (Cambridge end), a real hand (Realhand), a Radius surgical system (Radius surgical system), etc., or a robot, are developed to easily, rapidly, and stably rope a suture in a limited space.

Japanese patent laid-open publication No. 2006-25867 discloses a surgical suture in which a suture is woven in a length direction to have a hollow inside, and a suture tip is coupled to both end portions of the suture. Japanese patent laid-open No. 2003-19683 discloses a surgical manipulator for ligation and suturing to prevent damage to a living tissue. However, manipulators, such as a Davinci robot system (Davinci robot system) that facilitates suturing and knotting in endoscopic surgery, are rather expensive and require a large installation space, and thus cannot be widely used. Accordingly, there is a need for a suturing method that can be easily used at low cost, and a suture and needle for implementing the method.

Disclosure of Invention

Detailed description of the invention

The present invention provides a method for rapid and easy suturing in a limited space of a surgical operation, a tool for the method (suture support, needle housing, a suture with suture support and/or needle housing), and a method for manufacturing the tool.

Means for solving the problems

The present invention provides a suture thread which does not need to be tied with part or all of a knot which should be tied originally when the suture is sewed, a manufacturing method of the suture thread, a suture thread support body required by the suture thread, a needle accommodating body and a sewing method using the suture thread.

According to an aspect of the present invention, there is provided a support for preventing a tip of a suture thread from being caught by skin or tissue during suturing; and the support body is coupled with one end of the suture line. The other end of the suture thread is passed through the skin or tissue in the suture site by the suture needle to perform suturing. When sutured by a suture, the support acts as a knot, so that the end to which the support is coupled is fixed at the site where the suturing starts. Thus, no knotting is required during the suturing process, as there is no need to worry about the loosening of the suture. Furthermore, one end of the suture can be more firmly secured to the skin or tissue than if the suture had only one knot.

According to another aspect of the present invention, there are provided a needle accommodating body having a tube-like shape with a through hole penetrating through both ends, and a suture thread having the needle accommodating body. The needle holder may have the shape of a truncated cone or a truncated triangular cone, in which the diameter of the through hole increases from one end portion to the other end portion, or the shape of a cylinder or a corner post in which the diameter of the through hole is constant. If desired, the needle holder may be formed of a rigid or resilient material. The suture needle is inserted into the needle accommodating body. A portion of the needle body of the suture needle coupled to the needle housing may fit the shape of the through hole of the needle housing. The diameter of a part of the needle main body of the sewing needle is larger than that of the bottom end part of the needle accommodating body. The suture needle can be pulled from the bottom end portion of the needle accommodating body to remove the suture needle from the needle accommodating body. The suture needle is connected with the needle accommodating body.

According to another aspect of the present invention, there is provided a suture thread having a needle housing and a suture needle, wherein a portion of a needle body of the suture needle coupled to a bottom end of the needle housing is larger than the bottom end (an end having a relatively larger diameter) of the needle housing. The needle housing may have a tubular shape penetrating through the through-holes at both ends, a truncated cone or truncated triangular cone shape in which the diameter of the through-hole increases from one end portion to the other end portion, or a cylindrical or angular column shape in which the diameter of the through-hole is constant. The suture needle is connected with the needle accommodating body. The suture needle can be pulled from the bottom end portion of the needle accommodating body to remove the suture needle from the needle accommodating body.

According to another aspect of the present invention, a method of making a support and/or a needle holder is provided.

When a suturing needle having a needle housing is used, the suturing needle penetrates or inserts into other tissues surrounding the suturing section from the needle housing into the tissue in the final step of suturing. Then, the suture needle is pulled from the bottom end portion of the needle housing to remove the suture needle from the needle housing. Thus, the needle receptacle remains in the tissue after the needle is removed, and the suture thread used for suturing remains coupled to the needle receptacle. Therefore, even if the knot is not tied at the last part of the stitch, the stitch is not untied.

According to the present invention, the sewing needle can facilitate a firm sewing without tying a knot. When the suture thread having the supporting body and/or the needle-receiving body is used, a stable knot effect can be obtained without taking time to tie the knot. Thus, by an easy sewing technique, the sewing time can be significantly reduced. Further, the suture operation can be stably and easily performed without using an experienced suture technique.

Furthermore, when the suture according to the present invention is used, the suture operation can be completed by a single tool. Therefore, even if the area to be treated with the endoscope is minute, the suturing can be performed quickly and accurately.

Furthermore, when the suture, the suture needle, the needle holder, and the support body of the present invention are made of a material that is absorbable by a living body, a process of removing these elements after the operation may be unnecessary.

Detailed Description

The present invention will now be described in more detail with reference to the accompanying drawings, in which exemplary embodiments have been shown. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein, which are provided for the purpose of illustration and description, but rather for the purpose of providing a thorough and complete disclosure that more fully conveys the concept of the invention to those skilled in the art. In the drawings, the needle portions are exaggerated for easy understanding of the present invention. It will be appreciated that the length of the thread connected to the needle or needle holder is relatively long for practical use.

Fig. 1 shows a suture 10 with different supports 40 according to an embodiment of the invention. The support 40 has a diameter greater than that of the suture 10 and a shape such as a rod, a sphere, a cylinder, a cone, a pyramid, a truncated cone or a truncated pyramid, a disk, a dish, a polyhedron, etc., the present invention is not limited thereto. Support 40 can have any shape and size that supports suture 10 to prevent the ends of suture 10 from being pulled into the seam. The support 40 may be a uniform solid, or may have at least one hole at both ends of the support 40. For example, the supporting body 40 is a truncated cone and has a through hole penetrating through both ends of the supporting body 40. The diameter of the hole or cavity is larger than the diameter of the suture in use. The support 40 may be formed of, for example, nylon (nylon), polypropylene (polypropylene), for example, MESH (MESH), polyvinylidene fluoride (polyvinylidene fluoride), unsaturated polyester (polyester), stainless steel, titanium, etc., which are not absorbed into the living body, but the present invention is not limited thereto. Further, the support body may be formed of an absorbable material according to the purpose. For example, polylactic acid (polylactic acid), polydioxanone (polydioxanone), a copolymer of lactic acid (lactic acid) and glycolic acid (glycolic acid), etc. may be used, but the present invention is not limited thereto. When a material absorbable by a living body is used, the support body 40 does not need to be removed after suturing the human body.

A method of coupling a suture 10 to a support 40, comprising a method of melting a portion of the support coupled to an end of a bonded suture and/or the suture; a method of forming at least one hole (e.g., hole 41 of the support in fig. 8 (c)) by passing a suture through the hole and tying the suture together or tying the suture to a knot 42 having a diameter larger than the hole in the support; and a method of passing a suture passed through one aperture in an opposite direction through another aperture. However, the present invention is not limited thereto, and various methods may be used (FIG. 1)

The suture 10 with the support 40 of the present invention is inserted into a suture needle or coupled needle receptacle during use. The suture needle used may be formed of a non-absorbable material such as metal, or a material that is readily absorbable such as Polydioxanone (PDS). The whole sewing needle has a straight line or a curve shape. The needle tip may have a common and widely used shape, such as a spherical or sharpened (pointed) shape.

A method of coupling a suture 10 to a suture needle, comprising a method of inserting a suture in a hollow needle body and pressing the needle; a method of forming a hole (needle hole) in a needle and inserting a suture into the hole; and a method of cutting a groove in a needle wall having a cavity and guiding a suture over the groove. However, the invention is not limited and other different methods may be used herein.

When suturing with a suture thread having the above-described support, there is no need to individually tie knots at the beginning of the suturing, but the suture thread can also be tied more firmly than in the case of tying knots only. This facilitates suturing not only outside the human body but also inside the human body, such as endoscopic surgery.

FIG. 2 shows a suture 10 having a support 40 and a needle 30 according to one embodiment of the present invention. Referring to fig. 2, a support body in the form of a truncated cone is used, which has a through hole penetrating through both ends thereof. When a support having a larger diameter at the bottom surface, such as the support 40, is disposed to face the sewing needle 30, a stable knotting effect can be obtained.

Fig. 3 shows a needle housing 20 and a suture 10 having the needle housing 20 according to an embodiment of the present invention. The needle container 20 of the present invention is coupled to the suture thread 10, and the needle container 20 has a tubular shape of a through hole penetrating through both ends thereof, and has a shape of a truncated cone or a truncated triangular pyramid, and the diameter of the through hole thereof increases from one end to the other end. The diameter of the through-hole in the needle housing 20 is adjusted to allow the needle to pass therethrough and to be inserted into the through-hole, considering the diameter of the suture needle to be used.

A method of coupling a suture 10 to a needle housing 20, comprising a method of melting an end of the suture and/or coupling the suture to adhere the suture to a portion of the needle housing; and a method of forming at least one hole in a needle receptacle, wherein a suture is inserted into the hole and tied to a knot or tied together. However, the present invention is not limited thereto, and other various methods may be used.

The suture needle 30 is coupled to the needle housing 20. The suture needle 30 used in the present invention includes a needle body 31 and a needlepoint 32, the needlepoint 32 being formed at one end of the needle body 31. The diameter of the needle body gradually increases from the needle tip to the other end of the needle body 31. The suture needle 30 is inserted into the needle housing 20 to which the suture thread 10 is coupled, to perform suturing. In the final step of suturing, the suture needle 30 penetrates other tissues around the suture part, or penetrates or pierces other tissues around the suture part, to push the needle housing 20 into the tissues. The needle 30 is then removed by pulling the needle toward a bottom end 21 of the needle holder 20. In this way, the needle housing 20 without the suturing needle 30 is left in the tissue, and the suturing thread 30 for suturing is still coupled with the needle housing 20, so that no knot is tied in the final step of suturing, and the suturing can not be loosened.

Since the needle housing 20 has a conical or triangular shape, the diameter of the through hole increases from one end portion of the needle housing 20 to the other end portion thereof, and a portion of the needle main body 31 inserted into the needle housing 20 also has a diameter gradually increasing toward the other end portion thereof. Therefore, when the suture thread 10 is pulled after the suture needle 30 is inserted into the suture site during the suturing process, the suture needle 30 is not removed from the needle housing 20. For this, the through-hole in the needle housing 20 has a size sufficient to receive the suture needle 30. Further, the size of the through hole of the distal end portion 22 of the needle housing 20 is smaller than the size of the portion of the needle body 31 having the largest diameter.

FIG. 4 shows a needle containment body and a suture needle profile according to another embodiment of the present invention. When the needle accommodating body and a part or all of the needle main body of the sewing needle are larger than the bottom end portion of the needle accommodating body, a break can be formed, and therefore, when the sewing needle is pulled in a sewing direction during sewing, the sewing needle can be prevented from being removed from the needle accommodating body. The needle housing 20 has an outer shape of a tube having a through hole penetrating both ends thereof, and has an outer shape of a truncated cone or a truncated triangular pyramid, the diameter of the through hole of which increases from one end to the other end ((a) in fig. 4), or a cylindrical or corner-post, the diameter of the through hole of which is fixed ((b) in fig. 4). In the above method, the suture is coupled to the needle holder.

The suture needles used in the present invention may have a generally straight or curved profile. The needle tip may have a common and widely used shape, such as a spherical or sharpened (pointed) shape. The length and thickness of the needle tip can be adjusted to suit its purpose.

The needle container of the present invention may be formed of a material that is absorbable (absorbable) in the living body, such as polylactic acid (polylactic acid), polydioxanone (polydiaxanone), lactic acid (lactic acid), and Glycolic acid (Glycolic acid), etc., but the present invention is not limited thereto.

The present invention includes the suture of fig. 5 wherein the needle receptacle is coupled to both ends of the suture; the suture of fig. 1 to 3 and 6 to 8, wherein the needle housing is coupled to one end of the suture and/or the support is coupled to the other end thereof; and the suture of fig. 9, wherein the buttress couples the two ends of the suture.

The suture used in the present invention includes various shapes known in the art to which the present invention relates, and the suture of the present invention may be composed of one or two wires and include at least one winding portion (fig. 6 and 7). Fig. 7 (a) shows the insertion of the suture needle into the needle housing 20. Fig. 7 (b) shows the suture needle 30 removed from the needle housing 20.

In the present invention, a monofilament (monofilame) suture or a twisted (twisted) suture, or a monofilament suture or a twisted suture having barbs (barb) or cogs (cog) on the surface thereof, may be used as the suture 10. Barbed sutures are disclosed in Korean patent laid-open publication Nos. 10-2008-39345 and 10-2005-0108494, Korean New publication No. 20-320005 and U.S. Pat. No. 5931855, the contents of which are incorporated herein by reference. Barbs may be provided on the fibers according to a desired configuration and may be formed by any suitable method including those known in the art to which the present invention pertains. These methods may utilize knives or lasers, injection molding via press forming, stamping or cutting. A desired number of acute angle incisions are made in the suture. In the related art, the size of the barbs may be adjusted within a reasonable range according to the purpose. For example, the barbs formed on the suture may be about 30-100 microns, which may be adjusted depending on the diameter of the suture. The spacing of the barbs formed on the outer surface of the suture may be 100 microns to 1 mm, or more.

Figure 8 illustrates a barbed suture according to one embodiment of the present invention. Referring to fig. 8 (a), two or more sutures 10 are combined, wherein the front half and the back half of each suture 10 have a plurality of barbs 50 inclined in the same direction, and the barbs 50 are inclined at an angle of less than ninety degrees or more than ninety degrees and less than one hundred eighty degrees relative to the long axis of the suture 10. Then, one end of each suture thread 10 is coupled to the suture needle 30, and the other end of each suture thread 10 is coupled to the supporting body 40. In other embodiments, as shown in fig. 8 (b), one or more suture threads 10 have barbs 50 formed on the suture thread 10, and the barbs 50 are inclined in opposite directions in the front half and the rear half. For example, all barbs 50 of the front half are inclined at an angle of less than ninety degrees relative to the long axis of suture 10 toward the front end of suture 10, and all barbs 50 of the back half are inclined at an angle of less than ninety degrees relative to the long axis of suture 10 toward the back end of suture 10. Suture 10 is doubled back through the posterior eye 34 of needle 30. Then, both ends of any of the sutures 10 are coupled to the supporting bodies 40, or one end of any of the doubled sutures 10 is inserted into the suture needle 30 and pressed thereto, and the other end thereof is coupled to the supporting bodies 40. Referring to fig. 8 (c), the barbs 50 of the suture thread 10 are inclined in a direction different from that of the suture thread in (b). In this case, the suture 10 is folded in half after passing through the hole of the supporter 40 and both ends of the suture 10 are coupled with the suture needles 30. For example, two, three or four sutures 10 with barbs 50 may be used, and the number of sutures 10 may be adjusted depending on the thickness of the suture 10 or the purpose of use. The orientation of barbs 50 in suture 10 is schematically shown on the right half of any of figures (a), (b), and (c) of figure 8. For example, in the example of the suture 10 of the present invention made as described above, as shown in fig. 8, the barbs 50 are inclined toward the support 40, thus forming an acute angle with respect to the length of the suture 10. When barbs 50 have the above-described configuration, suture 10 can travel smoothly forward during suturing, and barbs 50 prevent suture 10 from traveling in a direction opposite the direction of suturing. When the needle 30 is cut after completion of suturing, the suture 10 does not come loose due to the barbs 50 and thus does not need to be tied with a knot. As such, when two or more sutures 10 having barbs 50 coupled to the support 40 and/or the needle holder 20 are used, a knot need not be tied and a more stable knot effect can be obtained. Furthermore, the single thread may be broken during suturing because the length of the suture thread is reduced by about half or more, as compared to the use of the conventionally used suture thread 10 having the barbs 50. However, when two or more sutures are used, the strength of the sutures may be increased by two or more times, and thus the sutures may reduce breakage. In addition, since the number of barbs or the contact surface of any one barb is increased by two or more, a more stable suture can be obtained and the reverse travel of the suture can be prevented.

In another embodiment of the present invention, the supporting body 40 is coupled to one end of the suture thread 10 and the suture needle 30 is coupled to the other end thereof, and the supporting body or cone 51 has a shape of a truncated cone or a truncated triangular cone and has a through hole penetrating both ends of the supporting body 40. The support 40 is inserted into the suture 10 at a position close to the needle 30, as shown in fig. 9. A truncated cone produces less friction and is more suitable as cone 51. The cone 51 is disposed such that a portion thereof (leading end) having a smaller diameter may face the needle 30 and two knots a and B each having a diameter larger than the leading end and formed respectively before and after the leading end ((a) and (B) of fig. 9). The two knots ((a) and (b) of fig. 9) are close to each other. Knot a prevents cone 51 from escaping after suturing and after needle 30 is removed. Knot B prevents cone 51 from being pulled back during suturing. The cone 51 remains at the end of the suture 10 even when the suture is completed and the needle 30 is removed. Therefore, there is no need to tie knots after suturing, and there is no concern that the suture 10 will not tie knots. Another truncated cone 51 or triangular cone may also be provided before the knot a and has a surface of smaller diameter (front end) facing the suture needle 30. Thus, the knot a can easily pass through the tissue during suturing, and the suturing can be easily completed ((b) of fig. 9). When the needle is removed after suturing, the front cone 51 is removed therewith, and thus the knot a and the rear cone 51 may prevent the suture thread 10 from being loosened, as shown in fig. 9 (a). Cone 51 may be formed from an absorbable material, such as a copolymer of poly (L-Lactide) and Glycolide (Glycolide), or a non-absorbable material, such as polypropylene. The length of cone 51 is, for example, about one to ten millimeters. However, the present invention is not limited thereto, and the length may be adjusted according to the location of use and the purpose. The diameter of the through hole in cone 51 that passes through both ends of support 40 may be: for example, a relatively small diameter, about one-half to two millimeters, at the front end and a relatively large diameter, about one-half to five millimeters, at the rear end. However, the present invention is not limited, and the diameter may be adjusted according to the thickness and purpose of the suture thread.

In the suture 10 having the barbs 50 and one end coupled to the support 40 (e.g., fig. 8) or the suture 10 having one end coupled to the support 40 and a knot and cone formed near a portion connected to the suture needle (e.g., fig. 9), the other end of the suture 10 not coupled to the support 40 may be coupled to the needle housing 20 or may be directly coupled to the suture needle 30 for use. When the needle container 20 as a knot is not used at the suture site where the suture is completed, the suture thread 10 is not detached due to the barbs 50 or the conical suture thread 51 even if the suture needle 30 is removed after the suture.

The suture provided according to the present invention may be formed of a non-absorbable (non-absorbable) material such as polypropylene (polypropylene), gold, stainless steel, titanium, nylon, polyvinylidene fluoride (polyvinylidene fluoride), unsaturated polyester, woven silk (braided silk), etc., or an absorbable (absorbable) material such as polydioxanone (polydiaxanone), although the present invention is not limited thereto.

According to an embodiment of the present invention, a method of manufacturing a suture having a suture needle and/or a needle housing includes an operation of coupling one end of the suture thread to a support and coupling the other end of the suture thread to the suture needle or the needle housing.

Coupling the suture to the support includes providing thermal energy to one end of the suture and/or a portion of the support to melt one end of the suture and the support, and joining the suture and the support with either or both ends melted. The coupling of the suture to the support may additionally include reducing a temperature of a portion where the suture and the support are coupled to each other. In addition, the method may include passing a suture through a hole or through a through-hole formed in the support and then tying a knot in the suture to have a diameter larger than the hole or through-hole of the support. In addition, the method may include passing the suture through the hole or through the aperture formed in the support and then passing the suture through the other hole formed in the support in an opposite direction. When two sutures are used, the invention may include passing the sutures through holes formed in the support or through holes formed in the support, and then tying the sutures together or tying the sutures with knots.

Coupling the suture to the needle may include placing the suture into the needle having the through-hole formed therein and pressing the needle; inserting a suture thread into a hollow formed in a suture needle; or to suspend a suture from an incision formed in the wall of a needle having a through-hole.

The coupling of the suture to the needle housing may include joining by melting one end of the suture and/or coupling a portion of the needle housing of the suture, and inserting the suture into at least one hole formed in the needle housing, and tying the suture to a knot or tying the suture together to be larger than a diameter of the hole.

According to an embodiment of the present invention, the method of manufacturing the suture includes an operation of combining two sutures, each of the sutures has a plurality of barbs inclined in the same direction at a front half portion and a rear half portion thereof, and one end of each of the sutures is coupled to the supporter and the other end thereof is coupled to the needle. Furthermore, in another embodiment of the present invention, the suture having barbs is doubled, the barbs are inclined in opposite directions in the front half and the rear half of the suture, and then the suture is coupled to the support at one end and to the needle at the other end.

In another embodiment of the present invention, a method of making a suture includes: coupling a suture buttress to one end of a suture; tying the suture thread to a knot at a portion near the other end of the suture thread; inserting a truncated cone (cone) (or truncated triangular cone) having a through-hole penetrating both ends thereof into the suture thread at the front side (needle direction) of the knot formed on the suture thread such that the front end thereof has a smaller diameter to face the suture needle; tying the suture to a knot before the taper; and coupling the other end of the suture to the suture needle. The method may further comprise inserting an additional cone between the needle and the knot before the cone such that the leading end has a relatively smaller diameter to face the needle.

A suture needle formed by the above method is within the scope of the present invention.

A suturing method using the suture thread with the needle accommodating body comprises the steps of using a suture needle in the needle accommodating body coupled with the suture thread to suture a suture part; pushing the suture needle through the tissue near the end of the suture site to embed or pass the needle receptacle through the tissue; and removing the suture needle by pulling the suture needle toward the bottom end portion of the needle accommodating body. When the needle housing with the suture is embedded in the tissue and fixed thereto, one end of the suture is also connected to the needle housing. Therefore, there is no fear that knots are not tied in the suture line, and there is no need to tie knots.

Industrial applicability

The suture thread, the needle holder and the suture thread support according to the present invention can be used for various kinds of surgical suture such as damaged muscle, blood vessel, nerve, wound or surgical incision, double eyelid surgery, wrinkle plastic surgery and the like.

A suture having one end coupled to a suture support, the suture support having one or more holes through which the suture passes, any hole having a diameter larger than the suture and preventing one end of the suture from being pulled into skin or tissue, and the other end of the suture being connected to a suture needle, wherein the suture support has the shape of a frustum of a cone or a frustum of a triangle and has a through-hole passing through both ends of the suture support, one end of the suture support has a relatively larger diameter and is disposed toward the suture needle, and a knot is tied to the suture passing through the through-hole of the suture support to prevent the suture support from being detached from the suture.

10. The suture of claim 9, wherein the suture is formed from more than two barbed wires.

11. The suture of claim 9, wherein the suture includes barbs.

12. A method of manufacturing a suture comprising coupling one end of a suture to a suture support and coupling the other end of the suture to a suture needle, the suture support having a diameter greater than the suture to prevent one end of the suture from being pulled into skin or tissue, wherein two lines having barbs inclined in the same direction are joined, and wherein one end of either of the two lines is coupled to the suture support and the other end is coupled to the suture needle.

13. A method of manufacturing a suture, the method comprising coupling one end of a suture to a suture support and coupling the other end of the suture to a needle receptacle, the suture support having a diameter larger than the suture to prevent one end of the suture from being pulled into skin or tissue, wherein two lines having barbs inclined in the same direction are joined, and any one of the two lines is coupled at one end to the suture support and at the other end to the needle receptacle.

14. A suture formed by the manufacturing method of claim 12 or 13.

15. A method of manufacturing a suture, the method comprising coupling one end of a suture to a suture support and coupling the other end of the suture to a suture needle, the suture support having a diameter greater than the suture to prevent one end of the suture from being pulled into skin or tissue, wherein a thread having barbs is doubled, the barbs being inclined in opposite directions in a first half and a second half of the thread, and one end of the thread being coupled to the suture support and the other end being coupled to the suture needle.

16. A method of manufacturing a suture, the method comprising coupling one end of a suture to a suture support and coupling the other end of the suture to a needle housing, the suture support having a diameter larger than the suture to prevent one end of the suture from being pulled into skin or tissue, wherein a thread having barbs is doubled, the barbs being inclined in opposite directions in a front half and a rear half of the thread, and one end of the thread being coupled to the suture support and the other end being coupled to the needle housing.

17. A suture formed by the method of manufacture of claim 15 or 16.

18. A method of manufacturing a suture having a suture buttress, the method comprising:

coupling the suture buttress to one end of the suture and tying the suture to a knot at a portion proximate the other end of the suture;

providing a cone having the shape of a frustum of a cone or a truncated pyramid and having a through-going hole running through both ends of the suture before facing the knot of a suture needle, a front end of the cone facing the suture needle having a relatively small diameter; and

the suture is tied to a knot before the cone and an end of the suture is coupled to the needle.

19. The method of claim 18, further comprising providing a further cone having the shape of a truncated cone or a truncated triangular cone with a through hole passing through both ends between the needle and the knot tied in front of the cone, a forward end of the further cone facing the needle having a relatively smaller diameter.

20. A suture formed by a method of manufacture of claim 18 or 19.
