Abstract
Description
Lifting thread
[0001] The present invention relates to a lifting room.
[0002] Recently, with the growing interest in skin beauty, thread-embedding therapy, which uses medical threads to improve sagging skin or wrinkles, has been developed and is being widely used.
[0003] Medical threads inserted through acupuncture stimulate and pull the surrounding skin tissue, strengthening muscles or improving sagging or wrinkled skin, and are absorbed into the treated skin over time.
[0004] In addition, the thread used in this acupuncture treatment is usually administered through a thread inserter, which is composed of a pipe-shaped insertion needle that extends long in the front-back direction and has a handle at the rear end, and a thread that is inserted into the insertion needle at one end and is exposed to the outside and extends rearward.
[0005] When a thread inserter inserts a needle into the body, the thread is drawn into the body. Once the thread reaches the desired location, the needle is withdrawn, leaving only the thread inside. The thread thus retained pulls and stabilizes the tissue, effectively improving sagging skin and wrinkles.
[0006] The prior art discloses a facial lifting suture including a plurality of anchor portions provided by penetrating a monofilament yarn, but there is difficulty in fixing the suture to the tissue within the skin during the procedure, and the fixation force to the target area of the biological tissue after the procedure is low, so there is a limit to increasing the lifting effect.
[0007] Therefore, in order to solve the problems described above, there is an emerging need to develop a lifting thread that prevents the lifting thread from moving or being pushed after being inserted into a living tissue, reduces pain to the patient, and improves the lifting effect.
[0008] The present invention provides a lifting thread that can be easily inserted into a lifting portion and can be firmly and stably fixed to the lifting portion.
[0009] However, the problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned can be clearly understood by those skilled in the art from the description below.
[0010] One embodiment of the present invention provides a lifting thread comprising: a suture; and one or more anchor portions provided at predetermined intervals on the suture; wherein one end of the anchor portion is fixed by being joined to the suture, and the other end of the anchor portion is spaced apart from the suture.
[0011] According to one embodiment of the present invention, the diameter of the anchor part can increase in the direction from one end of the anchor part to the other end.
[0012] According to one embodiment of the present invention, the angle formed by the anchor portion with respect to the suture may be 10° or more and 50° or less.
[0013] According to one embodiment of the present invention, the ratio of the distance from one end of the anchor part to the other end along the outer surface of the anchor part and the distance from the suture to the other end of the anchor part may be 1:0.3 to 1:0.6.
[0014] According to one embodiment of the present invention, the ratio of the distance (d2) from the suture to the other end of the anchor portion and the distance (d3) from one end of the anchor portion to the other end along the longitudinal direction of the suture may be 1:1.5 to 1:5.
[0015] According to one embodiment of the present invention, the lifting thread may further include a connecting portion that connects one end of the anchor portion to the suture.
[0016] According to one embodiment of the present invention, the anchor part may include two or more types of anchor parts having different shapes.
[0017] According to one embodiment of the present invention, the anchor part includes a first anchor part and a second anchor part, and an angle formed by the first anchor part with respect to the suture may be smaller than an angle formed by the second anchor part with respect to the suture.
[0018] According to one embodiment of the present invention, the lifting thread may further include a mesh member provided on the outer surface of the suture.
[0019] According to one embodiment of the present invention, a spiral engraving may be provided on the surface of the anchor portion along a direction from one end of the anchor portion to the other end.

[0030]
[0031] Hereinafter, the present invention will be described in more detail.
[0032] FIG. 1 is a drawing showing a lifting room according to one embodiment of the present invention, and FIG. 2 is a drawing showing an anchor part according to one embodiment of the present invention.
[0033] One embodiment of the present invention provides a lifting thread (1) comprising: a suture (100); and one or more anchor parts (200) provided at predetermined intervals on the suture (100); wherein one end of the anchor part (200) is fixed by being joined to the suture (100), and the other end of the anchor part (200) is spaced apart from the suture (100).
[0034] A lifting thread (1) according to one embodiment of the present invention can be easily inserted into a lifting area and can be firmly and stably fixed to the lifting area. In addition, the lifting thread (1) can reduce pain in human tissue and effectively prevent sagging. Meanwhile, the lifting thread (1) may include one end having a pointed shape to facilitate insertion into the treatment area, and when the one end having a pointed shape is included, the other end may include a terminal shape (e.g., a hook-shaped end) that allows the lifting thread (1) to be fixed to the tissue within the treatment area.
[0035] Referring to Fig. 1, the lifting thread (1) may include a suture (100) and an anchor portion (200). The lifting thread (1) may be a medical thread, and may be used, for example, as a suture for plastic surgery, a suture for cosmetic surgery, or a suture for fixing soft tissue.
[0036] According to one embodiment of the present invention, the suture (100) can be manufactured using materials used in the art. The suture (100) can be manufactured using a biodegradable polymer. For example, the suture (100) can include, but is not limited to, polydioxanone (PDO), polylactic acid (PLA), polyglycolide (PGA), or a copolymer of L-lactide and glycolide. The suture (100) can have a monofilament structure, and can also have a structure braided with multiple strands. In addition, the suture (100) can be formed of a soft material and can have a predetermined elasticity.
[0037] According to one embodiment of the present invention, the anchor part (200) can support the suture (100) after being inserted into the lifting area. The anchor part (200) can be made of a material that is not absorbed into the body, or can be made of an absorbable material depending on the purpose. For example, the anchor part (200) can be made of nylon, polypropylene (e.g., MESH, etc.), polyvinyliden fluoride, polyester, stainless steel, gold, titanium, silicone, Medpore, Gore-Tex, mesh, polylactic acid, polydioxanone (PDO, PDS), copolymer of lactic acid and glycolic acid, etc., but is not limited thereto.
[0038] According to one embodiment of the present invention, the anchor portions (200) may be provided in multiple numbers on the suture (100). The multiple anchor portions (200) may be provided on the suture (100) at regular intervals. In addition, the multiple anchor portions (200) may be provided on the suture (100) at irregular intervals. In addition, some of the multiple anchor portions (200) may be provided on the suture (100) at regular intervals, and other some may be provided on the suture (100) at irregular intervals. Meanwhile, the intervals of the anchor portions (200) may be appropriately adjusted according to the tissue type, structure, or thickness of the dermal layer or subcutaneous layer in the skin of the subject.
[0039] According to one embodiment of the present invention, the length (d3) of the anchor portion (200) may be 1 mm or more and 100 mm or less, but the length of the anchor portion (200) is not limited thereto, and may be adjusted in various ranges depending on the usage area and purpose.
[0040] According to one embodiment of the present invention, one end of the anchor part (200) is coupled to and fixed to the suture (100), and the other end of the anchor part (200) can be spaced apart from the suture (100). Referring to FIGS. 1 and 2, since one end of the anchor part (200) is coupled to and fixed to the suture (100), the anchor part (200) can maintain its position on the suture (100). Accordingly, the insertion of the lifting thread (1) can be facilitated. In addition, after the insertion of the lifting thread (1), the anchor part (200) can be more easily positioned at a desired point within the living body. Meanwhile, the other end of the anchor part (200) can be spaced apart from the suture (100). Through this, the anchor part (200) can be allowed to move freely with respect to the suture (100). Specifically, the anchor part (200) can move in the up-and-down and left-right directions with respect to the suture (100). Through this, the lifting thread (1) can be easily inserted into the target area. In addition, after the insertion of the lifting thread (1), the anchor part (200) can move smoothly on the suture (100), so that it can be effectively inserted into the dermal layer of the skin without being affected by the movement of the muscles of the subject, and pain of the subject can be reduced during the lifting procedure.
[0041] According to one embodiment of the present invention, the diameter of the anchor part (200) may increase along the direction from one end of the anchor part (200) to the other end. Referring to FIGS. 1 and 2, the cross-sectional size of the anchor part (200) may change with respect to the longitudinal direction of the suture (100). Specifically, the anchor part (200) may have a shape in which the cross-sectional size increases along the direction from one end (left side of FIG. 2) to the other end (right side of FIG. 2) of the suture (100). That is, the anchor part (200) may have a shape similar to a cone shape. When the anchor part (200) having a shape similar to a cone shape is used, the liftil thread (1) may be smoothly inserted into the dermal layer of the skin of the subject without experiencing great resistance during a lifting procedure.
[0042] According to one embodiment of the present invention, the angle formed by the anchor part (200) with respect to the suture (100) may be 10° or more and 50° or less. Referring to FIGS. 1 and 2, when the angle (θ) formed by the anchor part (200) with respect to the suture (100) is 10° or more and 50° or less, the lifting thread (1) can be inserted more smoothly into the lifting area, and after the insertion of the lifting thread (1), the anchor part (200) can move in the up-and-down direction and left-right direction with respect to the suture (100), so that it can effectively penetrate into the dermal layer of the skin without being affected by the movement of the muscles of the subject, and the occurrence of pain can be minimized.
[0043] According to one embodiment of the present invention, the ratio of the distance (d1) from one end of the anchor part (200) to the other end along the outer surface of the anchor part (200) and the distance (d2) from the suture (100) to the other end of the anchor part (200) may be 1:0.3 to 1:0.6. Referring to FIGS. 1 and 2, when the ratio of the distance (d1) from one end of the anchor part (200) to the other end along the outer surface of the anchor part (200) and the distance (d2) from the suture (100) to the other end of the anchor part (200) is within the above-mentioned range, the lifting thread (1) can be inserted more smoothly into the lifting area during the lifting procedure. Furthermore, the pain of the recipient can be reduced and sagging of the procedure area can be effectively prevented.
[0044] According to one embodiment of the present invention, the ratio of the distance (d2) from the suture (100) to the other end of the anchor portion (200) and the distance (d3) from one end of the anchor portion (200) to the other end along the longitudinal direction of the suture (100) may be 1:1.5 to 1:5. By adjusting the ratio of the distance (d2) from the suture (100) to the other end of the anchor portion (200) and the distance (d3) from one end of the anchor portion (200) to the other end along the longitudinal direction of the suture (100) within the aforementioned range, the lifting thread (1) can be inserted more smoothly into the lifting area. In addition, the impact on the skin tissue during the procedure can be reduced, and the pain of the subject can be reduced more effectively.
[0045] According to one embodiment of the present invention, the ratio of the distance (d3) from one end to the other end of the anchor part (200) along the longitudinal direction of the suture (100) and the distance (d1) from one end to the other end of the anchor part (200) along the outer circumference of the anchor part (200) may be 1:1.2 to 1:2. When the ratio of the distance (d3) from one end to the other end of the anchor part (200) along the longitudinal direction of the suture (100) and the distance (d1) from one end to the other end of the anchor part (200) along the outer circumference of the anchor part (200) is within the above-mentioned range, the lifting thread (1) can be inserted more smoothly into the lifting portion.
[0046] Figure 3 is a drawing showing a joint part and an anchor part according to one embodiment of the present invention.
[0047] According to one embodiment of the present invention, the lifting thread (1) may further include a coupling part (300) that couples one end of the anchor part (200) onto the suture (100). Through the coupling part (300), one end of the anchor part (200) can be more stably fixed onto the suture (100). The coupling part (300) may be formed of the same material as or a different material from the anchor part (200). In this case, when the coupling part (300) is formed of a material softer than the anchor part (200), one end of the anchor part (200) can be more stably fixed onto the suture (100), and at the same time, the anchor part (200) can move more freely in the up-down direction and the left-right direction with respect to the suture (100).
[0048] Although Fig. 3 discloses an embodiment in which the cross-section of the connecting portion (300) is circular, the shape of the connecting portion (300) is not limited thereto. The cross-section of the connecting portion (300) may have a non-circular shape. For example, the non-circular cross-section of the connecting portion (300) may be an oval, a triangle, a square, a parallelepiped, a trapezoid, a rhomboid, a pentagon, a hexagon, a cross, etc. In addition, the connecting portion (300) may have a rough surface on the circular or non-circular cross-section. When the connecting portion (300) has a rough surface, the area in which the connecting portion (300) and cell tissue can come into contact with the skin of the recipient during a lifting procedure is increased, thereby maximizing the anchoring effect.
[0049] Figure 4 is a drawing showing an anchor part according to another embodiment of the present invention.
[0050] According to one embodiment of the present invention, the anchor part (200) may include two or more kinds of anchor parts (200) having different shapes. Referring to FIG. 4, the anchor part (200) may include a plurality of first anchor parts (210) and a plurality of second anchor parts (220), and the shapes of the first anchor parts (210) and the second anchor parts (220) may be different from each other. For example, one second anchor part (220) may be provided between two first anchor parts (210). In addition, two second anchor parts (220) may be provided between two first anchor parts (210), or three second anchor parts (220) may be provided between two first anchor parts (210). However, the number of second anchor parts (220) provided between the two first anchor parts (210) is not limited to the above-described number, and may be appropriately adjusted depending on the intended use and the intended use area. When the lifting room (1) includes two or more anchor parts (200) of different shapes, the lifting room (1) can be inserted more smoothly into the lifting area and can be more stably accommodated in the lifting area.
[0051] According to one embodiment of the present invention, the anchor part (200) includes a first anchor part (220) and a second anchor part (220), and the angle formed by the first anchor part (210) with respect to the suture (100) may be smaller than the angle formed by the second anchor part (220) with respect to the suture (100). By adjusting the angle formed by the second anchor part (220) with respect to the suture (100) to be larger than the angle formed by the first anchor part (210) with respect to the suture (100), the lifting thread (1) can effectively penetrate into the dermal layer within the skin without affecting the insertion thereof.
[0052] According to one embodiment of the present invention, the distance (d2) from the suture (100) to the other end of the first anchor portion (210) may be smaller than the distance from the suture (100) to the other end of the second anchor portion (220). Through this, the lifting thread (1) can be inserted more smoothly into the lifting area, reducing pain to the patient and effectively preventing sagging of the treatment area.
[0053] According to one embodiment of the present invention, the lifting thread (1) may further include a mesh member (not shown) provided on the outer surface of the suture (100). The mesh member may include a plurality of pores and may have the form of a porous mesh. The mesh member may be bonded to the outer surface (surface) of the suture (100). To this end, methods such as extrusion molding, injection molding, weaving, braiding, post-processing, cutting, and heat bonding may be used. The mesh member may be used without limitation as long as it is a biocompatible material that is harmless to the human body. For example, the mesh member may include polydioxanone (PDO), polylactic acid (PLA), polyglycolide (PGA), or a copolymer of L-lactide and glycolide. By providing the mesh member on the suture (100), tissue ingrowth may progress, thereby making adhesion with the tissue more solid. Through this, the load applied to the anchor part (200) can be reduced over time.
[0054] According to one embodiment of the present invention, a spiral engraving (not shown) may be additionally provided on the surface of the anchor part (200) in a direction from one end of the anchor part (200) to the other end. By providing the spiral engraving on the surface of the anchor part (200), the lifting thread (1) can be inserted more smoothly into the lifting area during a lifting procedure. In addition, when the spiral engraving is provided on the surface of the anchor part (200), attachment and growth of cells within the tissue can progress, so that the adhesion between the tissue and the anchor part (300) can be made more solid.
[0055] According to one embodiment of the present invention, the lifting room (1) can be manufactured in a simple manner using injection, press, molding, laser, ultrasonic processing, etc., thereby reducing the manufacturing cost.
