Description

Technology Field

[0001] The present invention relates to a composite thread for improving wrinkles by inserting it into a part of the body where wrinkles occur for cosmetic purposes, and a method for manufacturing the same. Background Technology

[0002] Generally, wrinkles occur as skin elasticity decreases, and to improve them, cosmetics containing ingredients that improve elasticity are applied, or stimulating devices that stimulate the skin are used.

[0003] However, since skin-irritating cosmetics or devices are applied only to the outer layer, it is difficult to effectively improve wrinkles; consequently, there has been an increase in procedures recently that improve wrinkles by inserting threads into the skin.

[0004] The procedure to improve wrinkles by inserting threads can improve wrinkles by restoring skin elasticity through the skin's regenerative properties, by inserting biodegradable threads into the skin.

[0005] A conventional thread inserted to improve wrinkles is disclosed in Korean Published Patent Application No. 10-2023-0142302 (published Oct. 11, 2023) as a "composite thread cannula assembly for wrinkle improvement."

[0006] The above-described composite thread cannula assembly for wrinkle improvement comprises a mesh thread having a hollow formed of a biodegradable material formed to a predetermined length, a core thread formed of a biodegradable material inserted into the mesh thread to prevent the hollow portion of the mesh thread from collapsing, and a cannula for inserting the composite thread into the body, wherein the mesh thread includes a suture portion that sutures one end portion of the mesh thread, and the core thread is positioned such that the folded portion is inserted into the mesh thread with the mesh thread folded so that both ends are parallel to each other, with the folded portion facing the suture portion, in order to increase the strength of the core thread while minimizing the volume.

[0007] This conventional composite thread cannula assembly for wrinkle improvement was able to improve wrinkles using the composite thread.

[0008] However, conventional composite thread cannula assemblies for wrinkle improvement had the problem that the tip of the needle would pierce through the mesh threads during the procedure, making it difficult to perform and requiring a long procedure time.

[0009] In addition, there was a problem where the back part of the mesh thread was unraveled and not neatly arranged, resulting in a procedural defect where the skin surface became uneven after the procedure due to the loosened thread.

[0010] In addition, when forming the sutures of the mesh sutures, there were problems such as the production taking a long time, the inability to provide uniform quality, and a high defect rate because the worker had to form the sutures by hand one by one. The problem to be solved

[0011] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a composite thread for wrinkle improvement that not only improves the improvement of wrinkles by overlapping a first mesh thread and a second mesh thread to provide volume according to thickness, but also prevents the needle from slipping out through the mesh during the procedure, thereby enabling a quick and easy procedure.

[0012] In addition, the present invention aims to provide a composite thread for wrinkle improvement that can be administered quickly and easily by forming a thread suture portion that sutures the first mesh thread and the second mesh thread with a length sufficient to cover the needle hole, thereby preventing the needle from slipping out through the mesh during the procedure.

[0013] In addition, the present invention aims to provide a composite thread for wrinkle improvement that can prevent the occurrence of procedure defects where the skin is not properly arranged after the procedure by forming a shaping fusion portion at the end opposite the direction of the thread suture portion to tidy up the loosened thread.

[0014] In addition, the present invention aims to provide a composite suture for wrinkle improvement that can be mass-produced quickly, produces sutures of uniform quality, and minimizes the defect rate by forming the suture sealing portion and the finishing fusion portion through an induction heat fusion mechanism. means of solving the problem

[0015] A composite thread for wrinkle improvement according to an embodiment of the present invention for achieving the above-mentioned objective comprises a composite thread administered through a cannula, wherein the needle of the cannula is inserted into the inner circumference and the biodegradable yarn is formed in the shape of a mesh tube; a second mesh tube thread having an inner diameter larger than the outer diameter of the first mesh tube thread, wherein the first mesh tube thread is inserted into the inner circumference and the second mesh tube thread is formed in the shape of a mesh tube on the biodegradable yarn; and a thread suture portion that is heat-fused and sutured at a portion located at the tip of the needle while the first mesh tube thread is inserted inside the second mesh tube thread, wherein the thread suture portion is formed from the tip of the needle to a portion where a needle hole is located that penetrates around the needle, so as to prevent the tip of the needle from slipping out through the mesh when the needle is penetrated into the skin.

[0016] It may include a finishing fusion section that heat-fuses and organizes the unwound yarn around the first mesh tube thread and the second mesh tube thread located at the opposite end of the above thread suture section.

[0017] The above thread suture can be heat-fused by an induction heat-fusion mechanism that heats by electromagnetic induction.

[0018] The above-described induction heat fusion mechanism may include a heat fusion mold into which the ends of the first mesh tube thread and the second mesh tube thread are inserted to form the thread seal portion, and an induction heater installed in the heat fusion mold to heat by electromagnetic induction so as to melt the first mesh tube thread and the second mesh tube thread. Effects of the invention

[0019] According to the present invention, by overlapping the first mesh tube thread and the second mesh tube thread, not only can the improvement of wrinkles be enhanced by providing a sense of volume when inserted into the body, but the needle of the cannula can also be prevented from slipping out between the meshes of the first mesh tube thread and the second mesh tube thread, thereby enabling a quick and easy procedure.

[0020] In addition, the present invention forms a suture joint on the first mesh tube thread and the second mesh tube thread to prevent the needle of the cannula from slipping out through the mesh during the procedure, thereby enabling the procedure to be performed quickly and easily.

[0021] In addition, the present invention forms a finishing fusion part that organizes the unraveled thread at the end opposite to the direction of the thread suture part, thereby preventing the occurrence of procedural defects where the skin becomes irregular due to the unraveled thread after the procedure.

[0022] In addition, the present invention forms the suture sealing portion and the finishing fusion portion by an induction heat fusion mechanism, thereby enabling rapid mass production, as well as minimizing the occurrence of molding defects and providing composite sutures of uniform quality.

Specific details for implementing the invention

[0024] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

[0025] A composite thread (100) for wrinkle improvement according to an embodiment of the present invention can be inserted into the skin to increase skin elasticity through skin regeneration, thereby improving wrinkles, or can help in the regeneration of muscles or ligaments.

[0026] As illustrated in FIGS. 1 to 3, a composite thread (100) for wrinkle improvement according to an embodiment of the present invention may include a first mesh thread (110) and a second mesh thread (120).

[0027] The first mesh tube thread (110) can be formed from biodegradable yarn into the shape of a mesh tube.

[0028] Here, in this specification, the mesh tube may be in the form of a tube manufactured by forming yarn into a grid-shaped mesh.

[0029] The first mesh tube thread (110) may have an inner diameter into which the needle (210) of the cannula (200) can be inserted.

[0030] The second mesh tube thread (120) can be formed from biodegradable yarn in the shape of a mesh tube.

[0031] The second mesh tube wire (120) may have an inner diameter larger than the outer diameter of the first mesh tube wire (110), and the first mesh tube wire (110) may be inserted into the inner circumference of the second mesh tube wire (120) so that the second mesh tube wire (120) may overlap the first mesh tube wire (110).

[0032] The lengths of the first mesh tube thread (110) and the second mesh tube thread (120) vary depending on the treatment area, but they can be formed to be longer than half the length of the needle (210) of the cannula (200) and shorter than or equal to the total length of the needle (210).

[0033] When performing a procedure with the first mesh tube thread (110) or the second mesh tube thread (120) inserted into the needle (210) of the cannula (200), the needle (210) of the cannula (200) slips through the mesh of the first mesh tube thread (110) or the second mesh tube thread (120), and there is a problem in that only the needle (210) penetrates the body, while the first mesh tube thread (110) or the second mesh tube thread (120) cannot be inserted.

[0034] To prevent this, the present invention inserts the first mesh tube thread (110) into the second mesh tube thread (120) to minimize the tip of the needle (210) from slipping out through the mesh, thereby allowing for easy treatment. Furthermore, as the first mesh tube thread (110) and the second mesh tube thread (120) overlap and the mesh spacing becomes denser, skin regeneration is increased, thereby improving the skin's restorative power and enhancing the wrinkle improvement effect.

[0035] The biodegradable yarn forming the first mesh tube thread (110) and the second mesh tube thread (120) can be formed from any one of PDO (Poly Dioxanone), PLLA (Poly L-Lactic), and PCL (Poly Caprolactone), and can be formed by combining different yarns, and the first mesh tube thread (110) and the second mesh tube thread (120) can be formed from different types of yarn or the same type of yarn.

[0036] As illustrated in FIGS. 2 and 3, a composite thread (100) for wrinkle improvement according to an embodiment of the present invention may include a thread suture portion (130) and a finishing fusion portion (140).

[0037] The suture joint (130) sutures the open ends of the first mesh tube suture (110) and the second mesh tube suture (120) to prevent the needle (210) of the cannula (200) from being exposed in the direction of inserting the first mesh tube suture and the second mesh tube suture (120).

[0038] The suture joint (130) can be formed by heating and melting the first mesh tube suture (110) and bonding them together while the first mesh tube suture (110) is positioned partially outward from the end of the needle (210).

[0039] The end of the sutured portion (130) may have a rounded shape so that it can be easily inserted into the body, and the sutured portion (130) may be formed by an induction heat fusion mechanism (300) described below.

[0040] Since the first mesh tube thread (110) and the second mesh tube thread (120) are formed from biodegradable yarn, they melt even at a heating temperature of 50°C or higher, so there is no need to heat them to a high temperature.

[0041] The thread suture portion (130) may have a rounded end so that it can be easily inserted into the body while installed on the needle (210).

[0042] And, the thread suture portion (130) can be formed with a length (L) that covers the needle hole (211) formed in the needle (210) from the end of the needle (210).

[0043] Here, if the length (L) of the thread suture portion (130) is formed to be from the end of the needle (210) to the front of the needle hole (211), the length is relatively short, so when the needle (210) is inserted into the body, the end of the needle (210) can be prevented from slipping through the mesh between the first mesh tube thread (110) and the second mesh tube thread (120).

[0044] The cannula (200) on which the first mesh tube thread (110) and the second mesh tube thread (120) are installed may have a gripping portion (230) installed at the end of a hollow needle (210) inserted into the body, and a needle hole (211) communicating with the hollow of the needle (210) may be formed through the tip portion of the needle (210).

[0045] The arranging fusion section (140) may be located at the end opposite to the position of the thread stitching section (130), and the arranging fusion section (140) may prevent the threads of the woven first thread (110) and second thread (120) from unraveling by arranging the unraveled threads of the first thread (110) and second thread (120) by applying heat around the circumference of the first thread (110) and second thread (120) and heat fusing them.

[0046] The fusion section (140) can be formed by applying a preset heat to melt and fuse the first mesh tube wire (110) and the second mesh tube wire (120), and the fusion section (140) can also be formed by the following induction heat fusion mechanism (300).

[0047] The fusion section (140) can be formed by applying heat and applying pressure around the needle (210) while the first mesh tube thread (110) and the second mesh tube thread (120) are fitted onto the needle (210).

[0048] As illustrated in FIG. 4, the composite thread (100) for wrinkle improvement according to an embodiment of the present invention can form a thread sealing portion (130) and a finishing fusion portion (140) by an induction heat fusion mechanism (300).

[0049] The induction heat fusion mechanism (300) can heat and melt the first mesh tube thread (110) and the second mesh tube thread (120), and pressurize the melted portion to form a thread sealing portion (130) and a finishing fusion portion (140).

[0050] The induction heat fusion device (300) may include a heat fusion mold (310) and an induction heater (320).

[0051] The heat fusion mold (310) may have the shape of the outer circumference of the thread suture portion (130) and the finishing fusion portion (140) to form the thread suture portion (130) and the finishing fusion portion (140).

[0052] The heat fusion mold (310) can be positioned at the location of the thread sealing part (130) and the finishing fusion part (140), and each heat fusion mold (310) has a mold groove formed according to the shape of the thread sealing part (130) and the shape of the finishing fusion part (140), so that when the first mesh tube thread (110) and the second mesh tube thread (120) are melted, they can be formed according to the shape of the mold groove.

[0053] In the embodiment, a mold groove is formed in the shape of a through hole so that the heat-fusion mold (310) can be inserted by penetrating the needle (210) in the longitudinal direction, and when the first mesh tube thread (110) and the second mesh tube thread (120) are installed on the needle (210) of the cannula (200) and inserted along the longitudinal direction and melted, it is configured to be formed according to the shape of the mold groove.

[0054] The induction heat fusion device (300) may include an induction heater (320).

[0055] The induction heater (320) can generate heat by electromagnetic induction to heat and melt the first mesh tube wire (110) and the second mesh tube wire (120).

[0056] An induction heater (320) may be positioned in each heat fusion mold (310), and the induction heater (320) may be positioned in the center of the heat fusion mold (310) of the spiral coil and heat the first mesh tube wire (110) and the second mesh tube wire (120) that have entered the heat fusion mold (310).

[0057] The induction heater (320) can heat and melt the first mesh tube wire (110) and the second mesh tube wire (120) by heating the heat fusion mold (310) through the electromagnetic induction phenomenon that occurs in the center of the coil as high-frequency current flows through the coil.

[0058] Meanwhile, the induction heat fusion mechanism (300) may further include an intake / output section (not shown) that inserts the heat fusion mold (310) for forming the thread suture section (130) and the heat fusion mold (310) for forming the finishing fusion section (140) into the heat fusion mold (310) by penetrating them together in the longitudinal direction while holding the gripping section (230) of the cannula (200), and then extracts them in the opposite direction from which they were inserted after forming the thread suture section (130) and the finishing fusion section (140).

[0059] The intake and output section can be configured to reciprocate the gripping section (230) of the cannula (200) along the longitudinal direction of the needle (210) by means of a cylinder, belt, or gear combination in which the gripping clamp reciprocates, so as to bring in or take out the cannula (200) on which the first mesh tube thread (110) and the second mesh tube thread (120) are installed, while the gripping clamp holds the cannula (200).

[0061] We will now explain the interactions and effects between each component described above.

[0062] In the composite thread (100) for wrinkle improvement according to an embodiment of the present invention, a first mesh thread (110) is inserted into the needle (210) of a cannula (200), and a second mesh thread (120) has an inner diameter larger than the outer circumference of the first mesh thread (110) and is inserted outside the first mesh thread (110).

[0063] And, the first mesh tube thread (110) and the second mesh tube thread (120) located at the end of the needle (210) are positioned to protrude further than the end of the needle (210) and form a thread sealing portion (130) that is sealed by melting with heat so that the needle (210) does not protrude.

[0064] At this time, the thread suture portion (130) is formed to be longer than the length (L) at which the needle hole (211) formed in the needle (210) is located, so that the thread suture portion (130) can cover the needle hole (211), thereby preventing the needle (210) from protruding between the mesh of the first mesh tube thread (110) and the second mesh tube thread (120) when inserted into the body.

[0065] And, at the end opposite to the direction in which the thread suture portion (130) is located, the end is melted by heat to form a finishing fusion portion (140) around the circumference of the first mesh thread (110) and the second mesh thread (120) to prevent the thread from unraveling.

[0066] Here, the thread sealing portion (130) and the finishing fusion portion (140) can be formed by an induction heat fusion mechanism (300), and the induction heat fusion mechanism (300) can form the thread sealing portion (130) and the finishing fusion portion (140) by installing an induction heater (320) in a heat fusion mold (310) in which a corresponding mold groove is formed to form the thread sealing portion (130) and the finishing fusion portion (140), and heating the heat fusion mold (310) by the induction heater (320) to heat and melt the first mesh tube thread (110) and the second mesh tube thread (120) introduced into the heat fusion mold (310).

[0067] When the thread suture portion (130) and the finishing fusion portion (140) are formed by the induction heat fusion mechanism (300), the thread suture portion (130) and the finishing fusion portion (140) can be formed with uniform size and shape, so not only can the quality be standardized, but there is also the advantage of being able to mass-produce quickly.

[0068] In this way, when the thread suture portion (130) and the finishing fusion portion (140) are formed on the cannula (200), the gripping portion (230) of the cannula (200) is grasped and the thread suture portion (130) is inserted into the area to be treated. When the first mesh tube thread (110) and the second mesh tube thread (120) are completely inserted into the body, the procedure of the composite thread (100) can be completed by pulling out the cannula (200) in the opposite direction from which it was inserted, leaving only the first mesh tube thread (110) and the second mesh tube thread (120) in the body.

[0069] Of course, depending on the depth or size of the wrinkles in the treatment area, multiple composite threads (100) can be inserted to perform the procedure.

[0071] Accordingly, the composite thread (100) for wrinkle improvement according to an embodiment of the present invention can improve wrinkle improvement by overlapping a first mesh tube thread (110) and a second mesh tube thread (120) formed in the shape of a tube to maximize the number of pores, thereby enhancing skin regeneration through each pore.

[0072] In addition, since the second mesh tube thread (120) is inserted into the first mesh tube thread (110), the thickness of the composite thread (100) is increased to have volume, thereby not only making it easier to improve deep wrinkles, but also preventing the needle (210) from slipping out through the mesh during the procedure, allowing for rapid insertion at the correct location.

[0073] In addition, a thread suture portion (130) is formed at the end of the composite thread (100) to prevent the needle (210) from slipping out through the mesh during the procedure, thereby allowing for rapid insertion into the correct position.

[0074] In addition, a finishing fusion part (140) is formed at the end opposite to the direction in which the thread suture part (130) is located to prevent the threads of the first mesh thread (110) and the second mesh thread (120) from unraveling, thereby preventing side effects of the procedure caused by unraveled threads and allowing the procedure to be performed neatly as if the procedure area were finished, thereby improving satisfaction with the procedure.

[0075] In addition, the suture sealing portion (130) and the finishing fusion portion (140) can be formed by an induction heat fusion mechanism (300) to enable rapid mass production, and a composite suture (100) of uniform quality can be produced to minimize the defect rate.

[0077] Although embodiments of the present invention have been described above, the scope of the present invention is not limited thereto and includes all changes and modifications within the scope recognized as equivalents that can be easily changed by a person skilled in the art from the embodiments of the present invention.
