Endoscopic treatment tool

An endoscopic treatment tool comprising:

• a sheath;
• an operating wire inserted into the sheath and being configured to advance and retract;
• a basket part positioned at a distal side of the operating wire and formed by binding a plurality of elastic basket wires having helical shapes in a natural state;
• a distal end tip which binds and fixes distal ends of the plurality of basket wires at a distal end of the basket part;
• a binding part in which proximal end portions of the plurality of basket wires are bound together and fixed;
• and
• a support member disposed through the basket part along a central axis of the basket part, a proximal end portion of the support member being positioned inside the sheath, and a distal end portion of the support member being fixed to the distal end tip;
• and
• a connecting member positioned at a proximal side than the binding part, the connecting member connecting the proximal end portion of the support member with the operating wire inside the sheath such that the proximal end portion of the support member is along a longitudinal axis of the operating wherein the connecting member includes:
• a sliding part configured to slide with respect to the operating wire;
• and
• a holding part holding the proximal end portion of the support member at the position offset from the sliding part and along the central axis.
