Poly-p-dioxanon sutures (PDS) have been common in surgery as an absorbable material for years. After hardening by a particular procedure we use PDS pins as spacer material in interstitial I-125 implantations. The advantages of PDS are the mechanical qualities in contrast to catgut which causes hazards because of its soft consistency. PDS supports the efforts in optimization of seed distribution and dose application in interstitial radiotherapy.
聚对二氧环己酮缝线（PDS）作为一种可吸收材料在外科手术中已应用多年。通过特定程序硬化后，我们将PDS针用作间质碘-125植入术中的间隔材料。与肠线相比，PDS的优点在于其机械性能，肠线因其质地柔软会带来风险。PDS有助于优化间质放射治疗中籽源的分布和剂量应用。
