A treatment apparatus for use with an endoscope, by being inserted in a forceps channel of the endoscope, includes an elongated flexible element connected, at a distal end thereof, to a treatment instrument. In particular, the flexible element includes at least two bendable portions. A first bendable portion has a predetermined flexibility and a second bendable portion has a greater flexibility and is shorter than the first bendable portion. The second bendable portion is located between the first bendable portion and the treatment instrument and at least a portion of the first bendable portion and the entire second bendable portion protrude from a distal end of the forceps channel when the treatment instrument is in use.
