Pgla , one biodegradable material , is used to braid the conduits , which integrates the merits of its two aggregate ingredients . it is easy to adjust degrading rate to match the regeneration period of the nerve by changing the proportion of the two ingredients . the conduits are fabricated enlacing 2 . 2 millimeter stainless steel on the braiding machine with 16 spindles using 2700 tex yarns . four conduits with different structures are braided : common braided structure , braided structure using braided ply yarn , braided structure with inserted reinforcing yarn and adding bridge - yarn structure , the last two conduits are new attempts to look for good shape - keeping structure , being able to lead the nerve to regenerate effectively 本课题选用可生物降解材料聚乙丙交酯( pgla )为原料，它兼具两种聚合成分的优点，可以通过调节两者聚合的配比来调节它的降解周期，使与神经再生的周期相吻合。导管的制作是在16锭编织机上采用2700tex纱线进行带芯编织，芯子为直径2 . 2mm的不锈钢丝。共制作四种结构神经导管，分别为普通结构神经导管、编织线结构神经导管、加筋结构神经导管和加芯结构神经导管。
