摘　　要：本文应用扫描电镜、能谱仪、Ｘ射线衍射仪、金相检查等方法对宫腔内放置１０年以上ＶＣｕ２００宫内节育器（ＩＵＤ）进行了表面沉积物形态、元素成份、物相结构及金相变化等研究。结果表明，ＶＣｕ２００ＩＵＤ的腐蚀形成为不均匀腐蚀；表面沉积物元素为Ｃｕ、Ｃａ、Ｓ、Ｓｉ、Ｆｅ、Ｍｇ、Ｐ等；物相结构为Ｃｕ２Ｏ、ＣａＣＯ３、Ｃｕ。从长期放置含铜ＩＵＤ的安全性考虑，我们认为ＶＣｕ２００ＩＵＤ使用期限以７～１０年为宜，最长不超过１０年。The surface deposit form, elementary composition, mattergraphy struction and metallography change of VCu200 IUD used over 10 years were studied with scanning electron microscope, energy dispersive spectrophotometry and X-ray diffraction. The results showed that VCu200 IUD was unevenly corroded.The elements of surface deposits were Cu, Ca, S, Si, Fe, Mg, P and so on. Mattergaphy structions were Cu2O, CaCO3, Cu. In regard to the long term safety of copper IUD, we consider that the usage length for VCu200 IUD should be 10～12 years,no ever 10 years.
