[0008] In addition, the purpose is to provide a suturing device that can reduce patient pain after suturing by configuring it to be thin so that the incision hole that needs to be formed on the outside of the body is small when suturing inside the body is performed. means of solving the problem

[0009] To achieve the above objective, the present invention comprises: a rubber band having first and second fitting holes formed through it; first and second tubular members each having first and second spaces facing each other formed through it inside, assembled facing each other in a tubular shape, inserted together into the first fitting hole in a tubular shape to slide in the longitudinal direction, and having first and second guide holes facing each other formed through it on one edge; wherein a third guide hole is formed through it on one edge of the first tubular member, a first locking part formed on the outer surface that is inserted into the second fitting hole and guided in the longitudinal direction by being inserted into the third guide hole; and a suture thread installed so as to be detachable from the first and second tubular members and the locking rod in front of the first locking part. and, a suture needle that is inserted so as to slide in the first and second spaces, and the opposite end protrudes from the first and second guide holes and is bent at least once to face the front of the first and second tube members, with a third space formed through it inside, and is inserted into the first and second spaces by penetrating the incision site as it slides in the first and second spaces; wherein the suture thread is characterized in that a first loop and a second loop are superimposed by the rotation of the suture thread, and in that state, the first loop is inserted into the outer side of the first and second tube members and the second loop is inserted into the outer side of the first and second tube members and the catch rod, and one first end of the suture thread is inserted into the tip of the suture needle and inserted into the third space, and as the suture needle slides in the first and second spaces, it penetrates the incision site and the first and second loops, and the first and second loops are caught on the first catch when moving in the length direction of the catch rod and detach from the first and second tube members. Provides a suture device. Effects of the invention

[0010] The present invention has the effect of being simply composed of a rubber band installed to allow the first and second tube members and a locking rod to move, a suture needle installed to allow the first and second tube members to move, and a suture thread that sutures an incision formed inside or outside the body by operating the first and second tube members, the locking rod, and the suture needle.

[0011] For this reason, the present invention has the effect of simplifying the configuration for performing a suturing procedure, and due to the simplified configuration, the incision site can be sutured with simple operation.

[0012] The present invention has the effect of having the first and second tube members assembled to form a tube shape, the first and second tube members and the catch rod close by a rubber band, and the suture needle installed to slide within the first and second spaces formed inside the first and second tube members.

[0013] That is, the suturing device of the present invention has the effect of being configured to have a thin thickness.

[0014] For this reason, the present invention has the effect of reducing the size of the incision hole that must be formed on the outside of the body for the insertion of a suture device when performing a suturing procedure inside the body, and also has the effect of reducing the pain that the patient may feel after the suturing procedure.

[0015] The present invention has the effect of changing the positions of the first and second pipe members and the locking rod by utilizing the elasticity of the rubber band.

[0016] For this reason, the present invention has the effect of suturing the incision site by flexibly responding to the environment of the suturing procedure.

[0017] The present invention has the effect of suturing an incision site with a square knot or a surgeon's knot by pulling the first end of the suture that has penetrated the first and second loops or the first, second, and third loops, and the second end of the suture on the opposite side.

[0018] In addition, since the second loop remains fixed by being caught on the catch rod until a square knot or sergeant knot is formed, there is an effect of forming a tight square knot or sergeant knot.

[0019] For this reason, the present invention has the effect of preventing the incision site from opening due to the square knot or surgeon's knot of the suture that does not easily come undone.

[0020] The present invention has the effect of the first knot portion, in which both ends of the suture are twisted once, adhering closely to the incision site, rather than the second knot portion, in which both ends of the suture are twisted twice.

[0021] In other words, the second knot, which is formed by twisting both ends of the suture twice, adheres closely to the incision site and has the effect of preventing strong compression of the incision site.

[0022] For this reason, the present invention has the effect of preventing necrosis from occurring at the incision site by preventing strong compression of the incision site with a surgeon's knot.

[0023] The present invention has the effect of preventing the suture from detaching from the first and second tube members before it is caught on the first catch of the catch rod, because the suture, i.e., the first and second loops or the first, second, and third loops, is fitted into the fitting groove of the second tube member.

[0024] The present invention has the effect of positioning the first and second loops or the first, second, and third loops close to the incision site by means of the fixing groove of the second tube member.

[0025] In other words, it has the effect of preventing a gap from forming between the square knot or surgeon's knot and the incision site.

[0026] In addition, since the first and second ends of the suture are pulled while the first and second loops or the first, second, and third loops are inserted into the fixing groove, it has the effect of helping to form a square knot or a sergeant's knot.

[0027] For this reason, the present invention has the effect of preventing the incision site from being loosely sutured with sutures.

[0028] The present invention has the effect of preventing the suture from slipping off the suture needle before penetrating the incision site, because the first end of the suture is caught inside the bent portion of the suture needle.

[0029] Since a sharp needle portion is formed at one edge end of the first tube member, the present invention has the effect of allowing the first tube member to be easily inserted into the body while being less likely to get caught on the outside of the body.

[0030] For this reason, the present invention has the effect of allowing the suturing device to be easily inserted into the body and quickly suture the incision site.

[0031] Since the first and second guide protrusions of the first and second tube members are guided by each other, the present invention has the effect of preventing the first and second tube members from disengaging during a suturing procedure and improving straightness.

[0032] The present invention has the effect of easily penetrating the incision site with a suture needle because it pulls the body tissue with a pulling member to lift the incision site.

[0033] For this reason, the present invention has the effect of allowing the incision site to be sutured more delicately with sutures. Brief explanation of the drawing

Specific details for implementing the invention

[0035] Accordingly, an embodiment of the present invention as described above will be explained in detail with reference to the attached drawings as follows.

[0036] As illustrated in FIGS. 1 to 22, a suturing device (1000) according to an embodiment of the present invention is used to suture an incision (1) formed inside or outside the body with a suture thread (500).

[0037] The above-mentioned suturing device (1000) includes a rubber band (100), first and second tube members (200) (300), a stopper (400), a suture thread (500), and a suture needle (600).

[0038] The above rubber band (100) has first and second insertion holes (110) and (120) formed through it, respectively.

[0039] Here, the first and second fitting holes (110) (120) are formed parallel to each other on the rubber band (100).

[0040] The first and second tube members (200) (300) each have first and second spaces (210) (310) formed through them facing each other inside, and are assembled to face each other in a tube shape. They are fitted together into the first fitting hole (110) in the tube shape and slide in the longitudinal direction, and each has first and second guide holes (220) (320) formed through them facing each other on one edge.

[0041] Here, the first and second tube members (200) (300) are made of long, soft tubes or metal tubes, and the first and second spaces (210) (310) are formed facing each other by cutting a part of the first and second tube members (200) (300), and the first and second guide holes (220) (320) are formed facing each other by cutting a part of the first and second tube members (200) (300).

[0042] A third guide hole (230) is formed through one edge of the first tube member (200).

[0043] Here, the third guide hole (230) is formed by cutting a portion of the first pipe member (200) from one edge of the first pipe member (200) to the entrance of the first space (210).

[0044] The above-mentioned locking rod (400) is fitted into the second fitting hole (120), and a first locking part (410) is formed on the outer surface that is inserted into the third guide hole (230) and guided in the longitudinal direction.

[0045] Here, the locking rod (400) is made of a metal material or a long, soft tube, and the first locking part (410) is formed protruding by bending a part of the locking rod (400).

[0046] The above suture (500) is installed so as to be detachable from the first and second tube members (200) (300) and the catch rod (400) in front of the first catch part (410).

[0047] The above suture needle (600) is inserted so that one end slides into the first and second spaces (210) (310), and the opposite end protrudes from the first and second guide holes (220) (320) and is bent at least once to face the front of the first and second tube members (200) (300), and a third space (610) is formed through the inside, and as it slides in the first and second spaces (210) (310), it penetrates the incision area (1) and is inserted into the first and second spaces (210) (310).

[0048] As shown in FIGS. 13 and 14, the suture (500) has a first loop (510) and a second loop (520) formed continuously by the rotation of the suture (500) and overlaps, and in that state, the first loop (510) is fitted to the outer side of one edge of the first and second tube members (200) (300), and the second loop (520) is fitted to the outer side of one edge of the first and second tube members (200) (300) and the catch rod (400), and one first end (530) of the suture (500) is fitted to the end of the suture needle (600) and inserted into the third space (610), and as the suture needle (600) slides in the first and second spaces (210) (310), the incision site (1) and the first and second loops (510) (520) It will penetrate.

[0049] Here, the portion where the suture (500) intersects in the first loop (510) is formed opposite to the portion where the suture (500) intersects in the second loop (520).

[0050] And, when the first and second loops (510) (520) move along the length direction of the catch rod (400), they get caught on the first catch part (410) and detach from the first and second pipe members (200) (300).

[0051] And, the first end portion (530) is inserted into the third space (610) and is hung inside at least one bend (620) formed in the suture needle (600).

[0052] A fitting groove (330) into which a suture (500) is fitted is formed on the outer surface of one edge of the second tube member (300).

[0053] Here, the first and second loops (510) (520) are fitted into the fitting groove (330).

[0054] At one end of the edge of the second tube member (300), a fixing groove (340) is formed to position the suture (500), which has been detached from the first and second tube members (200) (300) by the sliding movement of the second tube member (300), so that the suture (500) is positioned close to the incision site (1).

[0055] Here, the fixing groove (340) is formed in a crescent shape at one edge of the second tube member (300).

[0056] A needle portion (240) is formed at one edge end of the first tube member (200).

[0057] Here, the needle portion (240) is formed like a sharp needle by slanting or sharpening one edge end of the tube member (200).

[0058] And, the first tube member (200) having the needle portion (240) formed thereon protrudes forward more than the second tube member (300).

[0059] On the surfaces of the first and second tube members (200) (300) that come into contact with each other, first and second guide protrusions (250) (350) that guide each other are formed.

[0060] Here, the first and second guide projections (250) (350) are formed to protrude longitudinally on the surfaces of the first and second tube members (200) (300) that come into contact with each other, at the rear of the first and second guide holes (220) (320).

[0061] The operation of the above-described suture device (1000) according to the embodiment of the present invention configured as above is described as follows.

[0062] As shown in FIGS. 1 to 22, an incision (1) formed on the outside of the body or an incision (1) formed on the inside of the body is positioned between the suture needle (600) and the first and second tube members (200) (300).

[0063] Then, the above suture needle (600) is slid toward the first and second tube members (200) (300).

[0064] Here, the suture needle (600) is guided through the first and second guide holes (220) (320) and slides backward along the first and second spaces (210) (310).

[0065] In addition, since the first end portion (530) of the suture thread (500) is caught inside the bent portion (620) of the suture needle (600), it does not detach from the third space (610).

[0066] Then, as shown in FIG. 16, the first end portion (530) that was fitted to the end of the suture needle (600) sequentially penetrates the incision area (1), the second loop (520), and the first loop (510) together with the suture needle (600).

[0067] And, as illustrated in FIG. 17, when the first and second loops (510) (520) are inserted into the first end portion (530) and the catch rod (400) is advanced in the longitudinal direction, the first catch portion (410) is guided into the third guide hole (230) and moves forward, and the first and second loops (510) (520) that were inserted into the insertion groove (330) are caught by the first catch portion (410) by the catch rod (400) moving in the longitudinal direction and come out of the insertion groove (330), thereby being detached from the first and second tube members (200) (300).

[0068] Here, the first and second loops (510) (520) are caught on the suture needle (600), and the second loop (520) remains caught on the catch rod (400).

[0069] Then, the above suture needle (600) is slid away from the first and second tube members (200) (300).

[0070] Here, the suture needle (600) is guided through the first and second guide holes (220) (320) and slides forward along the first and second spaces (210) (310).

[0071] Then, as illustrated in FIG. 18, the suture needle (600) is removed from the first and second spaces (210) (310) and the incision site (1), and the first end portion (530) of the suture thread (500) is released from the third space (610) as it is released from the inside of the bent portion (620) of the suture needle (600).

[0072] Then, the second tube member (300) is slid forward.

[0073] Here, the second guide projection (350) of the second tube member (300) slides while being guided by the first guide projection (250) of the first tube member (200).

[0074] Then, as shown in FIG. 19, the first and second loops (510) (520) are positioned close to the cut area (1) by the second tube member (300) which slides while being fitted into the fixing groove (340) of the second tube member (300).

[0075] That is, the first and second loops (510) (520) are fixed around the incision site (1).

[0076] Then, with the first and second loops (510) (520) inserted into the fixed groove (340), the first end (530) that penetrates the first and second loops (510) (520) and the opposite second end (540) are pulled.

[0077] That is, the first and second ends (530) (540) are pulled while the second loop (520) is fixed by being caught on the catch rod (400).

[0078] And, as shown in FIG. 20, when the first and second loops (510) (520) are connected by pulling the first and second ends (530) (540), the catch rod (400) is pulled out of the second loop (520), and the second tube member (300) is slid away from the cut portion (1).

[0079] Of course, the first tube member (200) is also moved away from the cut area (1).

[0080] For this reason, as shown in FIG. 21, the suture (500) sutures the incision (1) with a square knot (550) formed by the pulling of the first and second ends (530) (540).

[0081] Here, the square knot (550) is composed of a first knot portion that sutures the incision area (1) and is formed in a shape where both ends of the suture thread (500) protruding from both sides of the incision area (1) are twisted once to press the incision area (1), and a second knot portion that is formed in a shape where both ends of the suture thread (500) protruding from both sides of the first knot portion are twisted once to press the first knot portion.

[0082] As shown in FIG. 22, since a needle portion (240) is formed at the edge end of the first tube member (200), the first tube member (200) is easily inserted into the body where the incision (1) is formed.

[0083] As illustrated in FIGS. 23 to 31, in the suture device (1000) according to the first modified example of the embodiment of the present invention, the suture thread (500) has a connecting part (560a) that connects the space between the overlapping first and second loops (510) (520), and a third loop (560) formed by twisting is overlapped with the first loop (510) on the opposite side of the second loop (520) and fitted to the outer edge of one side of the first and second tube members (200) (300).

[0084] Here, the third loop (560) is fitted into the fitting groove (330) together with the first and second loops (510) (520).

[0085] And, the operation of the above-mentioned suture device (1000) is described as follows.

[0086] An incision site (1) formed on the outside of the body or an incision site (1) formed on the inside of the body is positioned between the above suture needle (600) and the first and second tube members (200) (300).

[0087] Then, the above suture needle (600) is slid toward the first and second tube members (200) (300).

[0088] Here, the suture needle (600) is guided through the first and second guide holes (220) (320) and slides backward along the first and second spaces (210) (310).

[0089] In addition, since the first end portion (530) of the suture thread (500) is caught inside the bent portion (620) of the suture needle (600), it does not detach from the third space (610).

[0090] Then, as shown in FIG. 26, the first end portion (530) that was fitted to the end of the suture needle (600) sequentially penetrates the incision area (1), the second loop (520), the first loop (510), and the third loop (560) together with the suture needle (600).

[0091] And, as illustrated in FIG. 27, when the first, second, and third loops (510)(520)(560) are inserted through the first end portion (530) and the catch rod (400) is advanced in the longitudinal direction, the first catch portion (410) is guided into the third guide hole (230) and moves forward, and the first, second, and third loops (510)(520)(560) that were inserted into the insertion groove (330) are caught by the first catch portion (410) by the catch rod (400) moving in the longitudinal direction and come out of the insertion groove (330), thereby being detached from the first and second tube members (200)(300).

[0092] Here, the first, second, and third loops (510)(520)(560) are caught on the suture needle (600), and the second loop (520) remains caught on the catch rod (400).

[0093] Then, the above suture needle (600) is slid away from the first and second tube members (200) (300).

[0094] Here, the suture needle (600) is guided through the first and second guide holes (220) (320) and slides forward along the first and second spaces (210) (310).

[0095] Then, as illustrated in FIG. 28, the suture needle (600) is removed from the first and second spaces (210) (310) and the incision site (1), and the first end portion (530) of the suture thread (500) is released from the third space (610) as it is released from the inside of the bent portion (620) of the suture needle (600).

[0096] Then, the second tube member (300) is slid forward.

[0097] Here, the second guide projection (350) of the second tube member (300) slides while being guided by the first guide projection (250) of the first tube member (200).

[0098] Then, as shown in FIG. 29, the first, second, and third loops (510)(520)(560) are positioned close to the cut area (1) by the second tube member (300) which slides while being fitted into the fixing groove (340) of the second tube member (300).

[0099] That is, the first, second, and third loops (510)(520)(560) are fixed around the cut area (1).

[0100] Then, with the first, second, and third loops (510)(520)(560) inserted into the fixed groove (340), the first end (530) that penetrates the first, second, and third loops (510)(520)(560) and the opposite second end (540) are pulled.

[0101] That is, the first and second ends (530) (540) are pulled while the second loop (520) is fixed by being caught on the catch rod (400).

[0102] And, as illustrated in FIG. 30, when the first, second, and third loops (510)(520)(560) are connected by pulling the first and second ends (530)(540), the catch rod (400) is pulled out of the second loop (520), and the second tube member (300) is slid away from the cut portion (1).

[0103] Of course, the first tube member (200) is also moved away from the cut area (1).

[0104] For this reason, as shown in FIG. 31, the suture (500) sutures the incision (1) with a surgeon's knot (570) formed by the pulling of the first and second ends (530) (540).

[0105] Here, the surgical knot (570) is composed of a first knot portion (570a) that sutures the incision (1) and is formed in a shape where both ends of the suture thread (500) protruding from both sides of the incision (1) are twisted once to apply pressure to the incision (1), and a second knot portion (570b) that applies pressure to the first knot portion (570a) and is formed in a shape where both ends of the suture thread (500) protruding from both sides of the first knot portion (570a) are twisted twice.

[0106] As illustrated in FIGS. 32 to 35, the suturing device (1000) according to a second modified embodiment of the present invention has a fourth space (710) formed through it internally so that the suture needle (600) is inserted so as to be able to slide along the suture needle (600).
