Abstract
An insertion instrument includes a shaft projecting, by being inserted through a hole of a fixing instrument, from a distal end of the fixing instrument toward a distal side, and a gas supply channel formed in the shaft section and having a jet port, which jets a gas, in a distal portion of the shaft section. The gas is supplied from a proximal side to the distal side toward the jet port in the gas supply channel, and an extension dimension along the longitudinal axis from the jet port toward the proximal side is greater than an extension dimension of the hole of the fixing instrument.

1-12. (canceled)
A medical treatment system comprising:
- an endoscope including an insertion section which extends along a longitudinal axis and is inserted into a body cavity, the endoscope including a distal portion, and an observation window provided in the distal portion and configured to observe a subject, and the endoscope further including a gas supply channel which is passed through an inside of the insertion section and has a jet port configured to jet a gas in a direction along the longitudinal axis;
- a first trocar having a first hole which keeps airtightness with the insertion section of the endoscope in a state in which the insertion section of the endoscope is inserted through the first hole, the first trocar being configured such that the distal portion of the endoscope projects from a distal end thereof;
- a treatment instrument including a treatment section configured to perform a treatment of a treated target by using energy;
- a second trocar having a second hole through which the treatment instrument is inserted, and an exhaust channel configured to exhaust the jetted gas from the body cavity to an outside, the second trocar being configured such that the treatment section of the treatment instruments projects from a distal end thereof;
- a gas supply tube connected to the gas supply channel of the endoscope;
- and
- a gas supply source to which the gas supply tube is connected, the gas supply source being configured to perform pressure adjustment and to supply the gas to the gas supply channel via the gas supply tube.
An endoscope comprising:
- an insertion section including a distal surface and extending along a longitudinal axis;
- an observation window provided on the distal surface and configured to observe a subject;
- a gas supply channel provided in the insertion section;
- and
- a jet port which opens to an outside of the insertion section on the distal surface of the insertion section, the jet port being configured to jet a gas, which is supplied through the gas supply channel, in a direction along the longitudinal axis.
A medical treatment system comprising:
- an endoscope including an insertion section which extends along a longitudinal axis and is inserted into a body cavity;
- a treatment instrument including a treatment section which is configured to perform a treatment of a treated target by using energy;
- a plurality of trocars through each of which the endoscope or the treatment instrument is inserted, each of the trocars having a hole through which the endoscope or the treatment instrument is inserted, at least one of the trocars includes an exhaust channel configured to exhaust a gas in the body cavity to an outside;
- and
- a gas supply source including a gas storage tank, and configured to jet a gas, via a gas supply tube, toward a treated region of the treatment instrument from a jet port which is located on a distal side with respect to a distal end of the trocar.
