Title: A thread containing variable region for reducing the pain
Inventor: KIM HYEON HO
IPC: A61F2/00
Filed: 2021-03-16
Abstract: The present invention relates to a lifting operation thread, composed of a non-elastic medical thread. The medical thread comprises: a fixing part formed on both sides and fixed to the skin; and a variable part located between the fixing parts to impart structural elasticity, wherein the fixing part (200) and the variable part (300) form the medical thread (100) as an integrally and continually connected type without a separate connection structure. The lifting operation thread, according to the present invention, can prevent pain and thread breakage due to muscle (tissue) damage by the variable part structurally contracting or relaxing according to the movement of the muscle (tissue). Since the structurally variable part is provided by processing non-elastic thread, the lifting operation thread is more cost-competitive than thread for lifting operations that use elastic threads such as Aptos thread, but can produce almost the same effect as those using elastic threads. In particular, the lifting operation thread, according to the present invention, is processed to a thickness within the thread thickness, it is possible to increase the traction effect than the existing lifting thread while reducing the diameter of the needle and thread at the time of injection, and since the thickness of the needle and thread can be reduced to minimize tissue damage, pain during an injection can be reduced. The lifting operation thread can be manufactured in a simple way through press, molding, ultrasonic processing, etc., and has the advantage of lowering the manufacturing cost.
