Abstract
A tubular treatment tool for an endoscope includes a flexible tubular member. A groove traversing the flexible tubular member in a direction of a diameter thereof is formed on the flexible tubular member. An operation wire is inserted in the flexible tubular member. The operation wire is movable relative to the flexible tube along an axis of the flexible tube. The distal end of the operation wire is secured to the flexible tube at a position on a distal end side with respect to the groove.
Claims26
