摘要:
To provide a cutting device capable of reliably cutting hard fibrous tissue with a simple structure with a small number of parts and cutting even when the object is difficult to cut, such as hard fibrous tissue in a recess portion, Which does not cause an increase in the burden of the endoscope and waste of time.SOLUTION: This guide pipe 20 has a guide pipe 20 which inserts the small diameter endoscope 10 in a state of being movable in the axial direction, and the distal end portion 22 of the guide pipe has a center Section 24a has an opening 23 which communicates from the inner wall to the outer wall of the guide pipe and which is farther from the distal end portion 22 of the guide pipe than both end portions 24b thereof, and the operation provided at the proximal end portion of the small diameter endoscope and the guide pipe , By changing the relative position in the axial direction between the small diameter endoscope and the guide pipe, the tissue to be cut 3 is placed between the edge 24 of the distal end portion and the distal end portion 12 of the small diameter endoscope A small-diameter endoscopic surgical instrument for clipping and cutting, and a small-diameter endoscopic surgical instrument having a distal end portion of a guide pipe cut at a tilted surface and having a blade thereon.(FIG.【課題】部品点数の少ない簡単な構成で、堅い繊維状の組織を確実に切断し、さらに、凹部にある堅い繊維状の組織等、対象が切断しにくい状態にある場合にも切断でき、患者の負担の増加や時間の浪費をもたらさない、細径内視鏡手術器具を提供する。【解決手段】細径内視鏡10を内挿し、軸方向に移動可能な状態で支持するガイドパイプ20を有し、ガイドパイプの遠端部22に、その遠端部側の縁24の中央部24aが、その両端部24bよりガイドパイプの遠端部22から遠い、ガイドパイプの内壁から外壁に通ずる開口23を有し、細径内視鏡とガイドパイプの近端部に設けられた操作部を用いて、細径内視鏡とガイドパイプの軸方向の相対的な位置を変えることにより、切断対象組織3を遠端部の縁24と細径内視鏡の先端部12の間に挟み込んで切断する細径内視鏡手術器具、さらに、ガイドパイプの遠端部を傾いた面で切断し、そこに刃を設けた細径内視鏡手術器具。【選択図】図4
