Title:
SUTURE MANUFACTURED USING POLY OCTYL CYANOACRYLATE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/060622
Kind Code:
A2
Abstract:
The present invention relates to a suture manufactured using poly octyl cyanoacrylate, and a method for manufacturing same, and aims to provide a suture and a method for manufacturing the suture, the suture which maintains tensile strength at the time of a surgical procedure and is absorbed into the body without causing any problems after the surgical procedure, by using poly octyl cyanoacrylate generated as a byproduct during the preparation of octyl cyanoacrylate. The present invention provides a method for manufacturing a suture, and a suture prepared using the method, the method comprising: a step for preparing octyl cyanoacetate by reacting cyanoacetic acid and octane alcohol by 1:1 equivalence ratio under the existence of a solvent; a step for reacting the octyl cyanoacetate and paraformaldehyde by 1:1 equivalence ratio under the existence of a solvent; a step for isolating and refining octyl cyanoacrylate after removing the solvent when the reaction is completed; a step for collecting poly octyl cyanoacrylate from the byproduct left from refining octyl cyanoacrylate; and a step for manufacturing a suture by a braid process after manufacturing a thread by melt spinning and extrusion molding the collected poly octyl cyanoacrylate.
