An overtube comprising:
- an insertion part, that is inserted into a subject and has a lumen, through which a device insertion part of a device for performing a medical procedure inside a body of the subject is removably inserted, the insertion part being inserted into the subject;
- and
- a tissue incising part that is disposed at a distal end side of the insertion part so as to cross the lumen and incises a tissue of the subject.
An overtube comprising:
- an insertion part, that is opened at a distal end, inserted into a subject, and has a lumen, through which a device insertion part of a device for performing a medical procedure inside a body of the subject is removably inserted, the insertion part being inserted into the subject;
- and
- a tissue incising part that crosses a distal end side of the lumen is disposed at the insertion part so as to allow withdrawing of the crossing state, and incises a tissue of the subject.
A medical procedure through a natural orifice, comprising:
- inserting a device that extends in an axial direction into a lumen disposed in an insertion part of an overtube and inserting the insertion part into a hollow organ through a natural orifice of a subject;
- guiding the insertion part to an incision target site while using an observation device to observe the incision target site;
- using a tissue incising part, disposed at a distal end side of the insertion part, to incise the incision target site and form an opening;
- and
- introducing at least one of an operative device and the overtube into an abdominal cavity via the opening.
