Claims

[Scope of Claim for Utility Model Registration] A flexible tube that can be inserted into and removed from a forceps channel of an endoscope, and a flexible tube that is radially drilled into the tube at a distance from the tip of the tube. a first cut that is bendable and extensible; a length-measuring section formed by the tube beyond the first cut; and a distance shorter than the length of the length-measuring section from the first cut to the base side. A second cut is made in the tube in the radial direction at the open position and allows the tube to bend and expand; and an elastic member that bends a second cut to form a T-shaped tip of the tube; In the endoscope length measuring tool having a flexible core rod that moves from a position to a position beyond the first cut, the length measuring tool for an endoscope has a flexible core rod that moves from a proximal end of the elastic member or the position of the tube to a position beyond the first cut. The tube is divided into a tip side and a base side at a position closer to the base side, and a connecting means is provided at the divided portion for detachably connecting the tip side and the base side of the tube. Length measurement tool for endoscope.
