    Abstract: The dilator has a central bore for a guide wire and a flexible distal portion merging continuously with an intermediate portion of constant cross-section. A proximal portion is convex in profile and merges continuously with the intermediate portion. The distal portion comprises a hemispherical tip followed by a conical section, a concave section and a convex section, respectively. The dilator is primarily for dilating oesophageal strictures when used in conjunction with an endoscope to place the guide wire and is urged along the wire using a threadably engaged insertion rod.

    Abstract translation: 扩张器具有用于导丝的中心孔和与恒定横截面的中间部分连续地合并的柔性远端部分。 近端部分是凸形的,并与中间部分连续地合并。 远侧部分分别包括半球形尖端,随后分别是圆锥形部分,凹形部分和凸形部分。 当与内窥镜一起使用以放置导丝时,扩张器主要用于扩张食管狭窄,并且使用可螺纹接合的插入杆沿着丝线被推动。
