    • An absorbable multi-filament suture having the excellent tenacity and in-vivo breaking strength retention and a manufacturing method thereof are provided to control the draft value by changing the cross-section area of a spinneret, thereby maximizing the alignment degree. A biodegradable polymer is manufactured. Thereafter, the manufactured biodegradable polymer is spun under the condition of the nozzle draft of 100 to 300 of the polymer passing through a spinneret so that the multi- filament is manufactured. Thereafter, the suture is manufactured from the manufactured multi-filament. The biodegradable polymer is poly glycol acid, poly lactide or the co-polymer of glycol acid and lactide. The diameter of the spinneret is 0.01 cm to 0.06 cm. The tensile strength of the multi-filament is 6.0 to 10.0g per fineness. The manufactured multi-filament suture has the in-vivo breaking strength retention of 80 to 95% after two weeks from braiding. When using the co-polymer of glycol acid and lactide, the ratio of the glycol acid and lactide is 95:5 to 80:20, preferably, 95:5 to 85:15.
    • 提供具有优异的韧性和体内断裂强度保持性的可吸收的多丝线缝合线及其制造方法,以通过改变喷丝头的横截面面积来控制牵伸值,从而使取向度最大化。 生产可生物降解的聚合物。 然后,将制造的生物降解性聚合物在通过喷丝头的聚合物的喷嘴通气量为100〜300的条件下纺丝,从而制造多丝。 此后,缝合线由制造的复丝制造。 可生物降解的聚合物是聚乙二醇酸,聚丙交酯或乙二醇酸和丙交酯的共聚物。 喷丝头的直径为0.01cm至0.06cm。 复丝的拉伸强度为每细度6.0〜10.0g。 制造的多丝线缝合在编织两周后具有80至95%的体内断裂强度保持率。 当使用乙二醇酸和丙交酯的共聚物时,乙二醇酸和丙交酯的比例为95:5至80:20,优选为95:5至85:15。

    • A flexible and biocompatible surgical mesh using mono filament for urinary incontinence and a manufacturing method for the same are provided to reduce a side effect caused by the meshes remaining in the human body, by gradually decomposing the mesh in the body by making the mesh of mono filament produced by composite-spinning degradable and non-degradable polymers in the type of segmented pie. A flexible and biocompatible surgical mesh contains mono filament produced by composite-spinning degradable and non-degradable polymers(1,2) in the type of segmented pie. In the section of the mono filament, degradable polymer is separated by non-degradable polymer. The non-degradable polymers are connected. The mesh contains the degradable polymer of 30~70vol.% and non-degradable polymer of 30~70vol.%. The degradable polymer contains single polymer of monomer or at least two selected from a group comprising glycolide, glycolic acid, lactide, lactic acid, epsilon-caprolactone, p-dioxanone, trimethylene carbonate, polyanhydride, and PHAs(Polyhydroxyalkanoates).
