- the thread inserter when the insertion needle is inserted into the human body, the thread is drawn into the human body by the insertion needle. . As such, the thread remaining inside the human body pulls and fixes the tissue inside the human body, thereby improving skin sagging or wrinkles.
- the larger the diameter of the inserted thread the greater the effect can be obtained.
- the diameter of the insertion needle increases, the diameter of the insertion needle is limited for reasons such as aggravating pain and causing side effects, and the diameter of the thread inserted into the insertion needle is also limited within a certain range.
- FIG. 1 shows a suture 1 for a lifting procedure having a conventional straight shape, the suture is divided into first and second zones around a certain point, the first zone (a) and the second zone ( At the periphery of b), a plurality of protrusions are inclined at an angle to face each other, so the protrusions in the first section lift the sagging skin and the protrusions in the second section serve as an anchor to hold the raised tissue from sagging again. .
- the suture 1 for a lifting procedure having such a conventional straight shape only plays a role of pulling the skin under the skin, the skin is continuously maintained in a rigid state, and there is a problem that a frown or a smiling expression cannot be made naturally. do.
- most of the sutures are made of non-stretchable materials, when the treated muscles move a lot, such as yawning or laughing out loud, pain is induced in the treated area or the tissue is torn, and in severe cases, a suture for a lifting procedure is used. It may break and reduce the lifting effect.
- the present invention intends to propose a new type of suture for a lifting procedure that can effectively solve the problems of the conventional suture for a lifting procedure.

- variable portion may be formed in the form of a spring by digging a suture so as to be spirally connected along the longitudinal direction of the medical thread, and the depth (h) of the expansion and contraction groove is preferably greater than the linear distance (H) from the center of the medical thread to the outer circumferential surface. do.
- the suture for a lifting procedure comprises a first area for firmly fixing the lifting area so as not to sag using a single medical thread, and a second area which is structurally and elastically designed to be embedded in a high-movement area.
- a first area for firmly fixing the lifting area so as not to sag using a single medical thread
- a second area which is structurally and elastically designed to be embedded in a high-movement area.
- the present invention also has the advantage of lowering the manufacturing cost because it is possible to form a relatively easily stretchable variable part using a press, molding, laser, ultrasonic processing, etc. even using a relatively inexpensive non-stretchable medical thread.
- a bending groove for releasing the support force that supports the acute-angled inclined jaw not to be pushed back is formed on the rear of the acute-angled inclined jaw, even if it is manufactured using a thread of the same diameter. As it is bent and rotated in the direction to fill the bending groove, it protrudes further in the outer direction of the suture to serve as an anchor, so it has the advantage of being able to fix the lifting part more firmly.
- FIG. 1 shows a suture for a conventional lifting procedure.
- Figure 2 schematically shows a variable lifting thread for pain reduction comprising a first region and a second region, according to an embodiment of the present invention.

- first region and the second region, and again the first region and the second region, are repeated along the longitudinal direction of the medical thread is also possible, like the first region, the second region and the first region. If at least one or more first and second regions are provided, both are achievable and fall within the scope of the present invention.
- first region having fixing grooves is provided on both sides of the second region having the variable portion, only the variable portion may be formed in the second region and the fixing groove may be formed only in the first region.
- the acute-angled inclined jaw 150 formed on one side of the fixing groove 200 may be manufactured on the outer circumferential surface of the medical thread through ultrasonic waves or fine blade processing.
- the medical thread usually uses a non-elastic material, but in some cases, even if it is made of a flexible material, the first region is a fixed part without a variable structure, and if a variable part having a variable structure is formed in the second region, the present invention It is possible to achieve the goals of preventing pain and preventing thread breakage, which are sought in the present invention.
- the straight yarn is illustrated as an embodiment having a circular cross-section, but it is also possible to have a non-circular cross-sectional shape in order to increase the surface area and more effectively form the protrusion.
- These non-circular cross-sections can be formed into ovals, triangles, squares, parallelepipeds, trapezoids, rhomboids, pentagons, hexagons, crosses, etc.
- These medical yarn yarns are formed by extrusion using a die having a circular cross-section. Since it is manufactured by cutting a polymer filament, the cross-section of the extrusion die can be changed to a desired cross-sectional shape of a specific shape, so it is also possible to manufacture a medical thread having a non-circular cross-section.
- a material such as polydioxanone (PDO), polylactic acid (PLA), or polyglycolide (PGA), which are biodegradable polymers, may be used.
- PDO polydioxanone
- PLA polylactic acid
- PGA polyglycolide
- the depth h of the expansion and contraction groove 160 formed in the variable part 300 is larger than the linear distance H from the center of the yarn used for manufacturing the suture for the lifting procedure to the outer peripheral surface (H). It is desirable to have a value.
- variable part 300 a plurality of V-shaped or U-shaped bends or grooves alternate in the left/right or up/down directions in the longitudinal direction are formed in a form alternating in the left and right directions, Structural elasticity can be imparted to the non-stretchable medical yarn due to the structure formed by such an alternating structure.
- a V-shaped or U-shaped expansion groove 160 between a pair of fixing parts 200 is in the left and right direction.
- a variable portion 300 having an alternating shape is formed, and a plurality of basic repeating units U of the variable portion 300 may be included.
- a bending groove 160 for releasing the supporting force of the acute angle inclined jaw is formed at a position spaced apart from the rear of the fixing groove 130 by a predetermined distance, so that the acute angle When the slanted jaw digs into the human tissue, it is bent and rotated in the direction to fill the bending groove 160 and protrudes further in the outer direction to dig deeper into the human tissue to be firmly fixed.
- the additional bending groove 160 of the fixing part 200 may be selectively applied to the suture for a lifting procedure according to the present invention.

It is preferable to form a distance excluding the thickness (d).
- the bent or groove portion of the yarn is not in direct contact with the subcutaneous tissue. As it is stretched inside the cylinder, irritation or damage to the tissue can be prevented, so that no pain is induced in the treatment area.
- the structure in which the variable part is positioned between the two fixing parts is integrally formed, so that the muscle (tissue) after being embedded in the subcutaneous tissue of the recipient It has the advantage of being able to naturally relax or contract according to movement.
- the suture for a lifting procedure according to the present invention is spaced apart from each other and between the fixing parts 200 formed on the outer circumferential surface of the medical thread, not due to the elasticity of the thread, but a variable part ( 300) is located, and by allowing the basic repeating unit including them to be repeated a predetermined number of times, not only can relax and contract naturally according to the movement of the skin muscle, but also a separate coupling structure is provided in the medical thread in which the fixing part 200 is formed.
- By being formed as an integral structure instead of a non-removable one it has a unique effect of being able to effectively contract and relax in a stably fixed state.
