Drainage tube introducer for endoscope

摘要

A drainage tube introducer for an endoscope includes a flexible guide wire having at a distal end thereof a puncturing portion adapted to be stabbed into an organic tissue. A drainage tube is fitted on a portion of the guide wire that is closer to the distal end thereof. The drainage tube is held on the guide wire by frictional resistance. A flexible pusher is loosely fitted on the guide wire axially movably so that the drainage tube is pushed out forwardly by the pusher.
