Description
本発明は、内視鏡用穿刺針装置及びチューブに関する。 The present invention relates to an endoscope puncture needle device and a tube .
本発明は、かかる不都合を解消して、外筒チューブ及び内筒チューブの座屈を抑制するとともに、優れた操作性を得ることができる内視鏡用穿刺針装置及びチューブを提供することを目的とする。 An object of the present invention is to provide an endoscopic puncture needle device and a tube that can eliminate such inconvenience, suppress buckling of the outer tube and the inner tube, and obtain excellent operability. And
前記目的を達成するために、本発明は、筒状の把持部と、該把持部の先端に連結され、内視鏡の処置具装着用チャネルに挿脱可能な外筒チューブと、該把持部の内部に挿入され、該把持部に対して進退自在である筒状の操作部と、該操作部の先端に連結されるとともに該外筒チューブの内部に配設され、該操作部とともに進退自在の内筒チューブと、該内筒チューブの先端に取着され、該操作部の進退に伴って、該外筒チューブの先端から出没自在の穿刺針とを備える内視鏡用穿刺針装置において、該外筒チューブは、ポリテトラフルオロエチレンを主成分とする樹脂材料からなり、該内筒チューブは、ポリエーテルエーテルケトンを主成分とする樹脂材料からなることを特徴とする。 In order to achieve the above object, the present invention provides a cylindrical gripping part, an outer tube connected to the distal end of the gripping part and detachable from a treatment instrument mounting channel of an endoscope, and the gripping part are inserted therein, and freely der Ru cylindrical operating portion forward and backward relative to the grip portion, disposed within the outer cylinder tube while being connected to the distal end of the operation portion, forward and backward together with the operating unit In an endoscope puncture needle device comprising: a free inner tube; and a puncture needle that is attached to the distal end of the inner tubular tube and can be moved forward and backward from the distal end of the outer tubular tube as the operation unit advances and retreats. The outer cylinder tube is made of a resin material containing polytetrafluoroethylene as a main component, and the inner cylinder tube is made of a resin material containing polyether ether ketone as a main component.
前記外筒チューブは、内径が１．５ｍｍ未満では前記内筒チューブの挿通を妨げる場合があり、内径が１．８ｍｍを超えてもそれ以上の効果を得ることができない。
また、前記外筒チューブ及び前記内筒チューブは、前記外筒チューブの内径と前記内筒チューブの外径との差が０．２ｍｍであるように構成してもよい。
また、本発明の内視鏡用穿刺針装置は、前記操作部は、前記把持部の基端側からその内部に挿入され、前記把持部の軸方向に沿って進退自在であるとともに、基端側に注射筒が装着されるように構成してもよい。
また、前記目的を達成するために、本発明は、内視鏡用の処置具装着用チャネルに挿脱可能な外筒チューブと、該外筒チューブの内部に進退自在に配設される内筒チューブとを備え、該外筒チューブは、ポリテトラフルオロエチレンを主成分とする樹脂材料からなり、該内筒チューブは、ポリエーテルエーテルケトンを主成分とする樹脂材料からなることを特徴とする。
本発明のチューブは、ＰＴＦＥとＰＥＥＫとを組み合わせることにより、両チューブの間に生じる摩擦係数を小さくすることができる。したがって、本発明のチューブは、前記内筒チューブにより、前記外筒チューブと併せて両チューブの座屈を抑制することができ、該両チューブを前記内視鏡の処置具装着用チャネルに円滑に挿入させることができる。また、前記内筒チューブを前記外筒チューブの先端から円滑に出没させることができる。
If the inner tube has an inner diameter of less than 1.5 mm, the inner tube may be prevented from being inserted, and even if the inner tube exceeds 1.8 mm, no further effect can be obtained.
The outer tube and the inner tube may be configured such that a difference between an inner diameter of the outer tube and an outer diameter of the inner tube is 0.2 mm.
In the puncture needle device for an endoscope of the present invention, the operation portion is inserted into the inside from the proximal end side of the gripping portion, and is movable forward and backward along the axial direction of the gripping portion. You may comprise so that a syringe can be mounted | worn by the side.
In order to achieve the above object, the present invention provides an outer tube that can be inserted into and removed from a treatment instrument mounting channel for an endoscope, and an inner tube that is disposed in the outer tube so as to be able to advance and retract. And the outer tube is made of a resin material mainly composed of polytetrafluoroethylene, and the inner tube is made of a resin material mainly composed of polyetheretherketone.
The tube of the present invention can reduce the friction coefficient generated between both tubes by combining PTFE and PEEK. Therefore, the tube of the present invention can suppress buckling of both tubes together with the outer tube by the inner tube, and both the tubes can be smoothly used as the treatment instrument mounting channel of the endoscope. Can be inserted. In addition, the inner tube can be smoothly projected and retracted from the tip of the outer tube.
