Abstract

An endoscope treatment tool includes a sheath and an incision device. The sheath includes a distal end portion having a first channel. The first channel extends internal to the distal end portion between a distal opening at a distal end surface of the distal end portion and a proximal opening at a main flow chamber. The incision device is inserted in the first channel and includes a second channel extending between a distal end of the incision device and a proximal end of the incision device. The endoscope treatment tool is switchable between a first mode and a second mode. In the first mode, a first path for fluid is formed between the main flow chamber and the first channel. In the second mode, a second path for fluid is formed between the main flow chamber and the second channel.
