Abstract: A surgical system includes: an overtube including a channel into which an endoscope is inserted; and an expansion device configured to ensure a surgical space by expanding an interior of a body at a distal side relative to a tip of the overtube. The expansion device includes a sheath and a wire configured to be protrudable from the sheath. The wire is configured to be switchable between a first configuration in which the wire protrudes from the sheath and a second configuration in which the wire protrudes from the sheath in a state where the wire is tilted, around a longitudinal axis, at an angle different from the first configuration.

Abstract: An overtube for an endoscope includes: a tube body having a main lumen through which the endoscope is inserted and an air-supply lumen through which gas flows; a fixing balloon provided on an outer peripheral surface of a distal end of the tube body, expandable outward from the outer peripheral surface and contractible toward the outer peripheral surface; an air supply device configured to send the gas to the air-supply lumen; and an airtight valve unit having a tubular portion communicating with the main lumen at a rear end of the tube body, the airtight valve unit closing the gap between the endoscope inserted through the tubular portion into the main lumen and an inner peripheral surface of the tubular portion.
