BIODEGRADABLE POLY PARA-DIOXANONE LIGATURE, METHOD FOR MANUFACTURING THE LIGATURE, KIT DEVICE USING THE LIGATURE AND METHOD FOR USING THE KIT DEVICE

摘要

Disclosed are a biodegradable poly para-dioxanone ligature, a method for manufacturing the ligature, a kit device using the ligature and a method for using the kit device. The present invention relates to a manufacturing method comprising: a step (S1) of crystallizing para-dioxanone generated from a dehydration reduction of diethylene glycol and performing a distillation at the vacuum condition of 10^-4 to 10^-2 torr; a step (S2) of stirring the para-dioxanone and at least one selected from a group consisting of caprolactone, trimethylene carbonate and glycolide and polyethylene glycol so as to prepare poly para-dioxanone; a step (S3) of drying the poly para-dioxanone to prepare a thread having a diameter of 50 to 100 µm; and a step (S4) of stretching the thread at an elongation of 5 to 10 times using an infrared ray source. The present invention also relates to a biodegradable poly para-dioxanone ligature manufactured by the method, a kit device using the ligature and to a method for using the kit device. Thus, it is possible to prepare poly para-dioxanone suitable for biocompatibility of a mammal from high purity para-dioxanone. When the thus-prepared poly para-dioxanone is implanted between the true skin and the panniculus of a mammal, the poly para-dioxanone may cause stimulation and generation of the skin fibroblast to improve wrinkles and cause skin volume to expand, thereby achieving the effects of plastic surgery.
