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 Once the thread reaches the desired location, the needle is withdrawn, leaving only the thread inside.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] Prior art discloses a suture having a knot-shaped position fixing element and a hollow interior of a tissue-connecting element, but it causes pain to the subject during the procedure and has low fixing strength to the target area of ​​the biological tissue after the procedure, which limits its ability to enhance the lifting effect. Furthermore, other prior art discloses a lifting member using a suture and a natural polymer, but does not disclose a configuration in which multiple bodies connected to the suture are fixed by a fixing member, making it difficult to fix the suture to the tissue within the skin during the procedure.

[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 will 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; one or more fixing portions provided at predetermined intervals on the suture; one or more anchor portions positioned between adjacent fixing portions and movably provided on the suture; wherein the anchor portions include a receiving groove provided at one end of the anchor portion and capable of receiving the fixing portion; and a through hole penetrating the anchor portion from one end of the anchor portion to the other end and receiving the suture.

[0011] According to one embodiment of the present invention, the receiving groove and the through hole may be provided continuously from one end of the anchor portion to the other end.

[0012] According to one embodiment of the present invention, the diameter of the receiving groove can be maintained the same along the direction from one end of the anchor portion to the other end, and the diameter of the through hole can be maintained the same.

[0013] According to one embodiment of the present invention, the cross-sectional size of the receiving groove may be larger than the cross-sectional size of the fixing portion.

[0014] According to one embodiment of the present invention, the cross-sectional size of the through hole may be smaller than the cross-sectional size of the fixing portion.

[0015] According to one embodiment of the present invention, the length ratio of the diameter of the fixed portion and the diameter of the receiving groove may be 1:1.1 to 1:2.

[0016] According to one embodiment of the present invention, the length ratio of the diameter of the fixed portion and the diameter of the through hole may be 1:0.3 to 1:0.8.

[0017] According to one embodiment of the present invention, the length ratio of the diameter of the through hole and the diameter of the receiving groove may be 1:0.25 to 1:2.

[0018] According to one embodiment of the present invention, the length ratio of the diameter of the fixed portion and the height of the receiving groove may be 1:0.5 to 1:2.

[0019] According to one embodiment of the present invention, the anchor part may further include an additional receiving groove provided at the other end of the anchor part and capable of receiving the fixing part.

[0032]

[0033] Hereinafter, the present invention will be described in more detail.

[0034] Figure 1 is a drawing showing a lifting room according to one embodiment of the present invention.

[0035] One embodiment of the present invention provides a lifting thread (1) including: a suture (100); one or more fixing parts (200) provided at a predetermined interval on the suture (100); one or more anchor parts (300) positioned between adjacent fixing parts (200) and movably provided on the suture (100); wherein the anchor part (300) includes a receiving groove (310) provided at one end of the anchor part (300) and capable of receiving the fixing part (200); and a through hole (320) penetrating the anchor part (300) from one end to the other end of the anchor part (300) and receiving the suture (100).

[0036] 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.

[0037] Referring to Fig. 1, the lifting thread (1) may include a suture (100), a fixing part (200), and an anchor part (300). 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 soft tissue fixation.

[0038] 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.

[0039] According to one embodiment of the present invention, the fixing part (200) may be provided on the suture (100) in various shapes. Although an embodiment in which the cross-section of the fixing part (200) is circular is disclosed in FIGS. 1 to 3, the shape of the fixing part (200) is not limited thereto. The cross-section of the fixing part (200) may have a non-circular shape. For example, the non-circular cross-section of the fixing part (200) may be an oval, a triangle, a square, a parallelepiped, a trapezoid, a rhomboid, a pentagon, a hexagon, a cross, etc. In addition, the fixing part (200) may have a rough surface on the circular or non-circular cross-section. When the fixing part (200) has a rough surface, the area in which the fixing part (200) and cell tissue can come into contact with the skin of the recipient during a lifting procedure is increased, thereby maximizing the anchoring effect.

[0040] According to one embodiment of the present invention, the fixing part (200) may be provided on the suture (100) to limit the range of movement of the anchor part (300). To this end, the fixing parts (200) may be provided in multiple numbers on the suture (100). The multiple fixing parts (200) may be provided on the suture (100) at regular intervals. In addition, the multiple fixing parts (200) may be provided on the suture (100) at irregular intervals. In addition, some of the multiple fixing parts (200) may be provided on the suture (100) at regular intervals, and other parts may be provided on the suture (100) at irregular intervals. The interval of the fixing parts (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.

[0041] According to one embodiment of the present invention, the anchor part (300) can support the suture (100) after being inserted into the lifting area. The anchor part (300) 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 (300) 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.

[0042] The length of the anchor portion (300) may be 1 mm or more and 100 mm or less, but the length of the anchor portion (300) is not limited thereto and may be adjusted in various ranges depending on the usage area and purpose.

[0043] FIG. 2 is a drawing showing an anchor part according to one embodiment of the present invention, and FIG. 3 is a drawing showing an anchor part according to another embodiment of the present invention.

[0044] Referring to FIGS. 1 and 2, the cross-sectional size of the anchor portion (300) can be changed with respect to the longitudinal direction of the suture (100). For example, the anchor portion (300) can have a shape in which the cross-sectional size increases along the direction from one end (the left side of FIG. 2) to the other end (the right side of FIG. 2) of the suture (100). That is, the anchor portion (300) can have a shape similar to a cone shape. When the anchor portion (300) having a shape similar to a cone shape is used, the lifting thread (1) can be easily inserted into the target area in the direction in which the cross-sectional size of the anchor portion (300) decreases during a lifting procedure. In particular, since the receiving groove (310) of the anchor portion (300) receives the fixing portion (200) provided on the suture (100), the liftil thread (1) can be smoothly inserted into the dermal layer of the skin of the subject without experiencing great resistance during the lifting procedure.

[0045] According to one embodiment of the present invention, the receiving groove (310) and the through hole (320) may be continuously provided from one end to the other end of the anchor part (300). Referring to FIGS. 1 and 2, the anchor part (300) may include the receiving groove (310) and the through hole (320). The suture (100) is inserted into the through hole (320) provided in the anchor part (300), so that the anchor part (300) can move on the suture (100). In addition, the receiving groove (310) of the anchor part (300) can receive the fixing part (200) provided on the suture (100). Through this, the movement range of the anchor part (300) on the suture (100) can be limited by the fixing part (200). The anchor part (300) can be provided on the suture (100) through a method in which the suture (100) is inserted into the receiving groove (310) and the through hole (320). At this time, since the receiving groove (310) and the through hole (320) are provided continuously in the direction from one end of the anchor part (300) to the other end, it can be easy to provide the anchor part (300) on the suture (100). In addition, the anchor part (300) can move more smoothly in a limited but straight line in any direction without shaking on the suture (100), which makes it easier to fix the anchor part (300) within the cell tissue in the dermal layer of the skin of the subject, thereby activating cell tissue regeneration and stimulating collagen production, thereby enhancing the effect of the lifting procedure.

[0046] According to one embodiment of the present invention, the diameter of the receiving groove (310) can be maintained the same along the direction from one end to the other end of the anchor part (300), and the diameter of the through hole (320) can be maintained the same. Referring to FIGS. 1 and 2, the diameter of the receiving groove (310) can be maintained along the direction from one end to the other end of the anchor part (300). By maintaining the diameter of the receiving groove (310), the receiving groove (310) can more stably accommodate the fixing part (200). In addition, the diameter of the through hole (320) can be maintained along the direction from one end to the other end of the anchor part (300). By maintaining the diameter of the through hole (320), the anchor part (300) can move more smoothly on the suture (100). Through this, the lifting thread (1) can be inserted more smoothly into the lifting area without shaking of the anchor part (300). In addition, the receiving groove (310) of the anchor part (300) can stably receive the fixing part (200), thereby minimizing pain that occurs during the process of inserting the suture (100) during the lifting procedure. In addition, since the anchor part (300) can move smoothly on the suture (100), it can effectively dig into the human tissue without being affected by the movement of the muscles of the subject.

[0047] According to one embodiment of the present invention, the cross-sectional size of the receiving groove (310) may be larger than the cross-sectional size of the fixing part (200). When the cross-section of the receiving groove (310) is circular, the cross-sectional size of the receiving groove (310) may refer to the diameter of the cross-section. In addition, when the cross-section of the fixing part (200) is circular, the cross-sectional size of the fixing part (200) may refer to the diameter of the cross-section. Meanwhile, when the cross-section of the receiving groove (310) is non-circular, the cross-sectional size of the receiving groove (310) may refer to the longest length passing through the center of the cross-section. In addition, when the cross-section of the fixing part (200) is non-circular, the cross-sectional size of the fixing part (200) may refer to the longest length passing through the center of the cross-section.

[0048] The cross-sectional size of the above-mentioned receiving groove (310) is formed to be larger than the cross-sectional size of the above-mentioned fixing part (200), so that the above-mentioned anchor part (300) can stably accommodate the above-mentioned fixing part (200). A plurality of fixing parts (200) may be provided on the above-mentioned suture (100), and the above-mentioned anchor part (300) may be provided between two adjacent fixing parts (200). As described above, the above-mentioned anchor part (300) can move on the above-mentioned suture (100), and the range of movement may be limited by the above-mentioned fixing part (200). At this time, when the movement of the anchor part (300) is limited in such a way that the fixing part (200) is accommodated in the receiving groove (310) of the anchor part (300), the shock to the tissue within the skin can be reduced when the movement of the anchor part (300) is limited during the lifting procedure, which can effectively reduce the pain that may occur to the patient during the lifting procedure. That is, compared to the case where the fixing part (200) is not accommodated inside the anchor part (300) because the fixing part (200) is larger than the receiving groove (310), the shock or pain that may occur during the lifting procedure can be reduced.

[0049] According to one embodiment of the present invention, the cross-sectional size of the through hole (320) may be smaller than the cross-sectional size of the fixing part (200). When the cross-section of the through hole (320) is circular, the cross-sectional size of the through hole (320) may refer to the diameter of the cross-section. Meanwhile, when the cross-section of the through hole (320) is non-circular, the cross-sectional size of the through hole (320) may refer to the longest length passing through the center of the cross-section. The cross-sectional size of the through hole (320) may be formed to be larger than the cross-sectional size of the fixing part (200), so that the fixing part (200) may not pass through the through hole (320). Through this, the movement range of the anchor part (300) on the suture (100) may be limited to a preset range.

[0050] According to one embodiment of the present invention, the length ratio of the diameter of the fixing part (200) and the diameter of the receiving groove (310) may be 1:1.1 to 1:2. Referring to FIGS. 1 and 2, the length ratio of the diameter (D1) of the fixing part (200) and the diameter (D2) of the receiving groove (310) may be 1:1.1 to 1:2. When the diameter of the fixing part (200) and the diameter of the receiving groove (310) are within the above-described range, the anchor part (300) can effectively receive the fixing part (200). Through this, the movement of the anchor part (300) is stably restricted, thereby reducing the impact on the skin tissue when the movement of the anchor part (300) is restricted, and effectively reducing pain that may occur to the subject. In addition, the lifting thread (1) can be firmly and stably fixed to the lifting area.

[0051] According to one embodiment of the present invention, the length ratio of the diameter of the fixing part (200) and the diameter of the through hole (320) may be 1:0.3 to 1:0.8. Referring to FIGS. 1 and 2, the length ratio of the diameter (D1) of the fixing part (200) and the diameter (D3) of the through hole (320) may be 1:0.3 to 1:0.8. When the diameter of the fixing part (200) and the diameter of the through hole (320) are within the above-described range, the movement of the anchor part (300) can be stably restricted. Through this, when the movement of the anchor part (300) is restricted, the impact on the skin tissue can be reduced, pain that may occur to the recipient can be effectively reduced, and the anchor part can be firmly and stably fixed to the lifting area.

[0052] According to one embodiment of the present invention, the length ratio of the diameter of the through hole (320) and the diameter of the receiving groove (310) may be 1:0.25 to 1:0.8. Referring to FIGS. 1 and 2, the length ratio of the diameter (D3) of the through hole (320) and the diameter (D2) of the receiving groove (310) may be 1:0.25 to 1:0.8. By adjusting the diameter of the through hole (320) and the diameter of the receiving groove (310) within the aforementioned range, the anchor portion (300) may be moved more smoothly on the suture (100) without restriction or shaking. Through this, the lifting thread (1) may be easily inserted into the lifting portion.

[0053] According to one embodiment of the present invention, the length ratio of the diameter of the fixing part (200) and the height of the receiving groove (310) may be 1:0.5 to 1:2. Referring to FIGS. 1 to 3, the length ratio of the diameter (D1) of the fixing part (200) and the height (L1) of the receiving groove (310) may be 1:0.5 to 1:2. When the ratio of the diameter of the fixing part (200) and the height of the receiving groove (310) is within the above-described range, the anchor part (300) can effectively receive the fixing part (200). Through this, the movement of the anchor part (300) is stably restricted, so that the shock to the skin tissue when the movement of the anchor part (300) is restricted can be alleviated, and the pain of the subject can be effectively reduced. In addition, the lifting thread (1) can be firmly and stably fixed to the lifting area.

[0054] In Fig. 3, an embodiment is disclosed in which the anchor part (300) is provided with a first receiving groove (310) and a second receiving groove (311, additional receiving groove).

[0055] According to one embodiment of the present invention, the anchor part (300) may further include an additional receiving groove (311) provided at the other end of the anchor part (300) and capable of receiving the fixing part (200). Referring to FIG. 3, a first receiving groove (310) of the anchor part (300) may be provided in a direction toward one end (left side of FIG. 3) of the suture thread (100), and a second receiving groove (311, additional receiving groove) of the anchor part (300) may be provided in a direction toward the other end (right side of FIG. 3) of the suture thread (100). That is, the first receiving groove (310) may receive the fixing part (200) located at the front of the anchor part (300), and the second receiving groove (311) may receive the fixing part (200) located at the rear of the anchor part (300). By accommodating the fixing portions (200) provided at the front and rear of the anchor portion (300), the lifting thread (1) can be inserted more smoothly into the lifting area. In addition, when the movement of the anchor portion (300) is restricted, the impact on the tissue within the skin can be alleviated, and the pain of the subject can be more effectively reduced.

[0056] According to one embodiment of the present invention, the length ratio of the height of the additional receiving groove (311) and the height of the receiving groove (310) may be 1:2 to 1:3. Referring to FIGS. 1 to 3, the length ratio of the height (L2) of the additional receiving groove (311) and the height (L1) of the receiving groove (310) may be 1:2 to 1:3. By adjusting the height ratio of the additional receiving groove (311) and the receiving groove (310) within the aforementioned range, the lifting thread (1) can be inserted more smoothly into the lifting area. In addition, when the height ratio of the additional receiving groove (311) and the receiving groove (310) is within the aforementioned range, the impact on the skin tissue when the movement of the anchor part (300) is restricted can be reduced, and the pain that may occur during the lifting procedure can be more effectively reduced.

[0057] 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 (300) can be reduced over time.

[0058] According to one embodiment of the present invention, a spiral engraving (not shown) may be additionally provided on the surface of the anchor part (300) in a direction from one end of the anchor part (300) to the other end. By providing the spiral engraving on the surface of the anchor part (300), 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 (300), 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.

[0059] 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.
