The major complication of transseptal catheterization, that of inadvertent perforation of other structures, can best be avoided by maintenance of the correct needle tip position during introduction and maneuvering of the assembly. The addition of a needle-stop to the transseptal needle shaft and a sterile ruler to check its present position assures the maintenance of the needle tip position, freeing the operator's concern for accurate location of landmarks. The method of utilizing and setting the needle-stop is described.
经中隔导管插入术的主要并发症，即意外穿孔损伤其他结构，可通过在组件插入和操作过程中保持正确的针尖位置来最好地避免。在经中隔针杆上增加一个针止动器，并使用一个无菌标尺来检查其当前位置，可确保针尖位置的维持，使操作者无需担心标志物的准确定位。本文描述了使用和设置针止动器的方法。
