A treatment device for use with an endoscope having a instrument channel for passage of an endoscopic instrument and a distal end is provided. The treatment device includes an end effector assembly with a base for placement at the distal end of the endoscope, an end effector rotatable relative to the base, and a mounting portion for attaching the base to the endoscope. The mounting portion is resiliently compressible and can be radially compressed for insertion into the instrument channel, whereby an expansion force of the resiliently compressed mounting portion retains the base relative to the distal end of the endoscope. The mounting portion also includes an opening longitudinally extending therethrough and communicable with the instrument chann 1 and sized for receiving an endoscopic instrument therethrough. |
