摘　　要：目的研制国产化的可控电熔微弹簧圈,并对其性能进行测试.方法采用抗拉伸、抗扭力、顺应性及疲劳性实验,检测微弹簧圈及其连接点的性能;体外接通直流电检测微弹簧圈的解脱时间;X射线透视下检测微弹簧圈标记的清晰程度.结果微弹簧圈及其连接点的抗拉伸强度为(83.53±2.47)cN(厘牛,1牛顿=103厘牛)、抗扭力强度为(134±13)圈、顺应性、疲劳性以及在体外接通直流电解脱实验取得了比较满意的结果,证明其安全性、稳定性与进口产品相近.结论 国产电熔可控微弹簧圈在其性能上达到或接近国外同类产品的水平,特别是在抗拉伸、抗扭力和解脱时间等方面优于国外产品,实验结果证明国产材料的安全性和稳定性.Objective To develop controllable electrolytic detachable coil, and test its properties. Methods After completion of testing anti--strain, anti-torque and fatigue test of coils and connection point, the coil is electrified to test its detachability and observed under X--ray. Results The results of an- ti-strain, anti-torque, flexibility and fatigue test were satisfactory. Conclusion The coil is as safe and effi- cient as imported GDC, especially its anti-strain, anti-torque properties and detaching time.
