Abstract
In an endoscopic treatment instrument having a plurality of sheaths, a supporting member for directly and indirectly supporting the plurality of sheaths, and a connecting member for directly/indirectly bringing the sheaths and an endoscope in a connected state are provided. The supporting member constrains a relative position of the plurality of sheaths and the connecting member can change the connecting state. Therefore, when an operator changes the connecting state of the connecting member, the positional relation of the endoscope and the plurality of sheaths can be changed, while the positional relation of the plurality of sheaths is still constrained. Accordingly, for example, left and right sheaths can be easily exchanged.
