PROBLEM TO BE SOLVED: To surely discharge smoke out of a peritoneal cavity by providing an aeroperitoneum means having a gas injecting means for injecting the gas into the peritoneal cavity to swell the peritoneal cavity and a sucking means for sucking the gas in the peritoneal cavity, and driving the aeroperitoneum means when a smoke generated by the cauterizing treatment of an affected tissue by a smoke detecting means. SOLUTION: In the medical treatment of the inner part of a peritoneal cavity under endoscopic observation, an aeroperitoneum device 8 is set, and CO2 gas is injected into the peritoneal cavity through a trocal 9 to expand the peritoneal cavity. A valve unit 27 is controlled by a control part 28 to regulate the temperature, flow rate or the like of the gas supplied from a bomb 26. When the internal pressure of the peritoneal cavity reaches a prescribed value, an endoscope 2 or a high frequency treatment tool 12 is inserted into the peritoneal cavity through trocals 9, 10, a high frequency cauterizing device 7 is started to cauterize the affected tissue in contact with the cauterizing electrode 29 of the high frequency treatment tool 12. When the smoke generated at this time is detected from the image projected on a TV monitor 17, a sucking pump 32 is operated to discharge the smoke out of the peritoneal cavity. |
