Abstract
An endoscope system has an overtube having a proximal end and a distal end, and a main lumen and a sub lumen; an endoscope having a channel and inserted into the main lumen; a flexible shaft being advanceable and retractable in the sub lumen; a curved needle having a proximal end and a distal end; and a needle holder configured at a distal end of the shaft to hold the curved needle, wherein the held curved needle is movable to a first position protruding from a distal end opening of the sub lumen, and due to a rotation around the longitudinal axis, part of the curved needle held by the needle holder is movable from the first position in front of the distal end opening of the sub lumen to a second position in front of the channel of the endoscope inserted into the main lumen.
