AI Technical Summary
Technical Problem
Conventional sutures for lifting treatments cause pain and risk breakage due to non-elastic materials and limited diameter, making natural facial expressions difficult and reducing lifting effectiveness.
Method used
A lifting thread with a locking portion and a length-variable portion that includes structural elasticity, formed by grooves or a spring-like shape, to prevent sagging and pain during muscle movement.
Benefits of technology
The thread provides firm lifting without sagging, prevents pain, and reduces breakage by integrating a stretchable section that adapts to muscle movement, while being cost-effective to manufacture.

Abstract
The present invention relates to a lifting thread having an elastic variable part that uses a normal medical thread that is relatively inelastic, and that firmly fixes the lifting area without sagging, while a structurally elastic variable part is formed in any part of the medical thread, so that pain is not induced at the treatment area even when muscles move significantly, such as when laughing or yawning, and the medical thread does not break. The present invention is characterized in that the medical thread includes a locking part formed on both sides of a fixing groove formed on the outer surface of the medical thread, with a first fixing section and a second fixing section facing each other, and a length variable part formed in a spring shape so that elasticity can be generated between the locking sections, and the spring shape of the length variable part stretches when an external force is applied, imparting elasticity to the medical thread.
