我们在推广应用输精管可复性注射栓堵法时,常出现栓堵剂经穿刺孔返流到阴囊皮肤的现象。其时,栓子多为哑铃形或其他形状,达不到有效堵管的目的,日后若取栓复通,也必麻烦。为此,笔者试作如下探讨。一、原因分析: 1.潜在缝隙:在安置输精管阻断镊开始时,圆环内输精管处于常压。逐渐拧紧阻断镊螺旋,环边压榨的组织一部分移向环内。由于环的束缚,该段输精管受压不断增高。当阴囊较厚或夹住的软组织较多时,压力尤高。栓堵剂为胶状予聚体,加压注入后,若注入压力足以将该段输精管象吹气球一 We promote the use of vas deferens refastenable injection plug method, often appear plugging agent through the puncture hole back to the scrotum skin phenomenon. At the time, mostly embossed dumbbell-shaped or other shapes, not up to the purpose of effective plugging tube in the future if you take suppository, will trouble. To this end, I try the following discussion. First, the cause of the analysis: 1. Potential gap: In the beginning of placement of vas deferens tweezers, the ring within the vas deferens at atmospheric pressure. Gradually tighten the tweezers to block the screw, the ring around the squeeze part of the organization moved to the ring. Due to the shackles of the ring, the vas deferens are under increasing pressure. When the scrotum thick or clamped more soft tissue, the pressure is particularly high. Plugging agent for the gel-like polymer, after the injection of pressure, if the injection pressure is sufficient to the section of the vas deferens like a balloon inflatable
