PROBLEM TO BE SOLVED: To provide a tube apparatus with a puncture function capable of performing puncture to a position to curve greatly from a body surface implantation position, utilizing characteristics of a distal end treatment apparatus of a robot arm having free operability and broad movable area in surgery using a scope-assisted support robot.SOLUTION: A tube apparatus with a puncture function comprises: an outer cylindrical pipe 1 made of flexible resin having a leading end chamfered in a tapered shape; an inner needle 3 insertably/extractably inserted in a form that a tip is protruded from the outer cylindrical pipe; and an outer cylindrical pipe base and an inner needle base 4 connected to the outer cylindrical pipe and the inner needle, and connected so as to be detachable and to be fixed. The inner needle is formed of a flexible wire composed of a metal needle at the leading end formed to be 7-15 mm long, and a metal wire strand that extends to the metal needle. An organ, etc. are punctured during surgery by a scope-assisted surgery support robot, and the outer cylindrical pipe is indwelled and used as a passage to and from the outside of a body.【課題】鏡視下支援ロボットを用いた手術において、自在な操作性及び広い可動域をもつロボットアームの先端処置具の特徴を活かし、体表刺入位置から大きく回り込むような位置への穿刺を可能とする穿刺機能付きチューブ器具を提供する。【解決手段】テーパー状に面取りされた先端を備えた可撓性樹脂よりなる外筒管1と、該外筒管より刃先を突出する形態で挿脱自在に内挿する内針3と、前記外筒管及び内針に接続し着脱自在かつ固定可能に接続される外筒管基及び内針基4より構成し、前記内針は、長さ7mm以上、15mm以下に形成される先端部の金属針と、該金属針に延設する金属撚線よりなるフレキシブルワイヤーにより形成する。そして、鏡視下手術支援ロボットによる手術のさいに臓器等に穿刺して、外筒管を留置して体外との通路として用いる。【選択図】図1
