Being the thread which is used for the suture after the technique of the software nylon

摘要

PPROBLEM TO BE SOLVED: To provide soft nylon suture thread suitable for suturing an oral cavity region when the oral cavity region is sutured after an operation, by considering the fact that, since silk thread, where bacteria grow, is often used in a conventional manner while nylon, which does not become a vehicle for the bacteria, comes to be used in recent years, but is hard to cause a large node, is easily untied, and as a result, requires a hard and long thread end, so as to allow a patient to have pain. PSOLUTION: Nylon 6 and nylon 66 are copolymerized for obtaining a thread to be used for suturing the oral cavity region after the operation. The copolymer is transferred by a metallic grid melting machine and filtered. The polymer is measured in a vessel consisting of a filter and a spinning cap. Melted filament passes through a tub in order to be cooled with liquid and is solidified, drawn by diameter to be required, heated, and re-extended to have a necessary length. The acquired thread is reduced in tissue reactions and enlarged in strengths and extension. Then the node is made to be firm, the suturing thread end is made to be shorter, and its material is soft, so that a stimulation is reduced at the suturing thread end. PCOPYRIGHT: (C)2005,JPO&NCIPI
