Summary: | PROBLEM TO BE SOLVED: To provide a treatment instrument for an endoscope capable of inserting a guide wire into a guide wire lumen easily when a multi-lumen sheath is provided.SOLUTION: A treatment instrument includes a second sheath 12 in which a slit 12e for moving a guide wire into or out of a first lumen is formed, and a sheath holding part in which a guide wire insertion opening 20b having a slit 20c and a main opening 20d is formed. A first end part of the second sheath 12 is formed with a first side part cut surface 12g and a second side part cut surface 12h that intersect in the shape of X, an axial direction cut surface formed by cutting in parallel with a center axis O12 from an end surface 12k, an opening surrounded by the first side part cut surface 12g, the second side part cut surface 12h, and the axial direction cut surface, and communicated with the first lumen at a position overlapping with the main opening 20d, and a piece-like part.SELECTED DRAWING: Figure 10
【課題】内視鏡用処置具において、マルチルーメンシースを備える場合に、ガイドワイヤをガイドワイヤルーメンに容易に挿通することができるようにする。【解決手段】処置具は、第1ルーメンにガイドワイヤを出し入れ可能なスリット12eが形成された第2シース12と、スリット20cと主開口20dとを有するガイドワイヤ挿入用開口20bが形成されたシース保持部と、を備え、第2シース12の第1端部には、X字状に交差する第1の側部切り込み面12gおよび第2の側部切り込み面12hと、端面12kから中心軸線O12と平行に切り込んで形成された軸方向切り込み面と、第1の側部切り込み面12g、第2の側部切り込み面12h、および軸方向切り込み面で囲われ主開口20dに重なる位置の第1ルーメンに連通する開口部と、片状部と、が形成される。【選択図】図10 |
