Abstract
A length-measuring device comprises a flexible tube having a first slit and a second slit disposed rearwardly of the first slit, said tube being bendable at each of the first and second slit, and said tube further having a length-measuring portion extending forwardly from the first slit to a distal end of said tube; and means for bending said tube at the first and second slits. Typically, the bending means is a wire which has a connection relation with the length-measuring portion to pull the same. The length-measuring portion is coated with regularly arranged scale marks. After being projected from a forceps channel of an endoscope, the length-measuring portion is pulled to assume a T-shape. The length-measuring portion can be disposed at the center of a field of vision of the endoscope, and also can be easily brought into intimate contact with a target affected part. In a reference color display device, the length-measuring portion is replaced by a distal end portion coated with three primary colors.
