Abstract
A locking mechanism for an endoscopic overtube comprising a generally tubular member having a slot extending from the distal end to the proximal end of the tubular member for insertion of an endoscope into the lumen configured to slidably receive the endoscope. The overtube has a second, smaller lumen configured to receive an elongated member. The slot has an interdigitating configuration with a plurality of interlocking members that join together to close the overtube. The second lumen connects the interlocking members to receive the elongated member therein to align and securely close the slot around the endoscope in the larger lumen. The elongated member in the second lumen connects the ends of the tubular member to keep the slot closed during an endoscopic procedure. A sleeve can be used at the distal end of the overtube to maintain closure of the slot.
