An object of the present invention at the time of water supply, and local cleaning for cleaning the part of the operative field, it is possible to and intraperitoneal cleaning for cleaning widely within the abdominal cavity, at the time of aspiration, without having to involve the abdominal cavity within the organization, and the pneumoperitoneum gas to provide an endoscopic surgical water-suction cleaning tube that can suck the cleaning solution, etc. without suction. . A outer tube 20 includes a first hollow hole 22p hollow cylindrical shape which is formed cylindrical portion 22 tip 23 at one end is joined. The first through hole 28 of the plurality of the distal end region 28s of the cylindrical portion 22 is formed, the second through hole 29 is formed in the tip 23. The inner cylinder 30 is formed a second hollow hole 32p is, as one end 32t is opposed by providing a gap between the tip portion 23 of the outer tube 20, within the first hollow hole 22p of the outer tube 20 is placed, an opening 32k is in a direction away from the closest position to the distal end 23 of the outer tube 20 and is movable along a first hollow hole 22p. Be water and suction through a second hollow hole 32p of the inner cylinder 30. . [Selection Figure Figure 3.【課題】送水時に、術野の一部を洗浄する局所洗浄と、腹腔内を広く洗浄する腹腔内洗浄とが可能であり、吸引時に、腹腔内組織を巻き込むことがなく、かつ気腹ガスを吸引せずに洗浄液等を吸引できる内視鏡手術用送水・吸引洗浄管を提供する。【解決手段】外筒20は、第1の中空孔22pが形成された中空円筒状の筒部22一端に先端部23が接合されている。筒部22の先端側領域28sに複数の第1の貫通孔28が形成され、先端部23に第2の貫通孔29が形成されている。内筒30は、第2の中空孔32pが形成され、一端32tが外筒20の先端部23との間に間隔を設けて対向するように、外筒20の第1の中空孔22p内に配置され、開口32kが外筒20の先端部23に最も接近した位置から離れる方向に、第1の中空孔22pに沿って移動可能である。内筒30の第2の中空孔32pを介して送水と吸引が可能である。【選択図】図3
