Abstract
【解決手段】 CO2ガスを供給して膨らませた患者腹部に複数のトラカールを穿刺させて、第1のトラカール37には処置具1が挿入され、第2のトラカール47には硬性内視鏡4が挿入されている。硬性内視鏡4の先端部には観察窓92が設けられ、この観察窓92の表面に反って流れるようにCO2ガスを間欠的に噴射する噴射ノズル93が具備されている。噴射ノズル93から噴射されるCO2ガスの噴射量が腹腔内から漏出するガスの漏出量以下となる条件下で、噴射ノズル93から噴射されるCO2ガスの噴射圧と噴射時間とを任意に設定可能なガス供給制御手段7が具備されている。

Claims (3)
- 体腔内膨出用の加圧ガスを供給して膨らませた被検体腔内に複数のガイド管を穿刺させて、前記複数のガイド管のうち1本のガイド管には内視鏡が挿入され、他の1又は複数のガイド管には処置具を挿入して処置を行う内視鏡システムであって、
前記内視鏡の挿入部先端に設けられる観察窓に前記加圧ガスと同じガスを清浄用ガスとして間欠的に供給して、前記観察窓の表面に沿って流れるように清浄用ガスを噴射する噴射ノズルと、
前記噴射ノズルから噴射される前記清浄用ガスの噴射量が前記体腔内から漏出する前記気腹ガスの漏出量以下となる条件下で、前記噴射ノズルから噴射される前記清浄用ガスの噴射圧と噴射時間とを設定可能な清浄用ガス供給制御手段と、を有することを特徴とする内視鏡システム。 - 前記内視鏡システムは、前記加圧ガスを供給する加圧ガス供給装置を有し、この加圧ガス供給装置には、前記体腔内の圧力を検出する圧力検出手段が具備され、この圧力検出手段は前記体腔内の圧力が所定圧力以下になったときには、前記加圧ガスを前記体腔内に供給し、
前記ガス供給手段は、前記加圧ガス供給装置から供給される前記加圧ガスの供給量と、前記噴射ノズルから噴射される前記清浄用ガスの噴射量との合計が、前記体腔内から漏出される前記加圧ガスの漏出量と同等になるように制御することを特徴とする請求項1記載の内視鏡システム。 - 前記加圧ガスの噴射量は、前記腹腔内から漏出する前記加圧ガスの漏出量の半分以下であることを特徴とする請求項2記載の内視鏡システム。
