Abstract: A medical device insertion method includes: inserting an endoscope into an overtube until a distal end of the endoscope protrudes from a distal end of the overtube; grasping a part of the endoscope protruding from the distal end of the overtube and inserting the endoscope into the large intestine until the distal end of the endoscope is between the splenic flexure and the sigmoid colon of the large intestine; and inserting the overtube together with the endoscope into the large intestine until the distal end of the endoscope is beyond the splenic flexure while grasping the overtube from an outer radial direction so as to deform the overtube in an inner radial direction until an inner surface of the overtube is pressed against an outer circumferential surface of the endoscope, and then inserting the overtube into the large intestine until a reinforced region is placed in the splenic flexure.

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.
