SURGICAL SUTURE MATERIAL,ITS APPLICATION AT TIME OF SURGERY,AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide an easily usable and reliable surgical suture material which is easily usable and reliable and enables simple and inexpensive production by forming a surgical suture material as absorbable synthetic polymer out of a glycolidetrimethylene carbonate copolymer which has a monomer exhibiting a statistic distribution with the content of glycolide of a specified value. SOLUTION: A surgical suture material as absorbable synthetic polymer is formed out of a glycolide-trimethylene carbonate copolymer which has a monomer exhibiting a statistic distribution with the content of glycolide of 76 wt.% or more. The surgical suture material herein used is formed into a monofilament with the diameter of 0.001 or 0.8 mm and the content of glycolide is 78 wt.% or more of the total copolymer. Moreover, the content of glycolide is 80-99 wt.%, especially 83-93 wt.% of the total copolymer. The suction period in vivo should be 35-91 days, some times 42-56 days and the degree of crystallization be 15-40%.
