Description
上記目的を達成するため、本発明は以下の手段を提供する。
本発明の一態様は、可撓性を有する長尺の可撓管と、該可撓管の先端に接続され相互に開閉可能である第１把持部材および第２把持部材とを備え、該第１把持部材および前記第２把持部材は、該第１把持部材および前記第２把持部材が閉じた閉状態において相互に対向する第１内面および第２内面をそれぞれ有し、前記第１内面は、相互に並列する一対の受け部と、該一対の受け部の間に形成された溝とを有し、前記一対の受け部および前記溝は前記閉状態において前記可撓管の長手軸に沿う方向にそれぞれ延び、前記第２内面は、前記閉状態において前記溝と対向し前記長手軸に沿う方向に延びる突起部を有し、該突起部の少なくとも一部の頂面は、前記長手軸に対して傾斜する傾斜面を有し、該傾斜面は、前記溝の基端側に向いた先端側部分と、前記溝の先端側に向いた基端側部分とを有し、前記一対の受け部、前記先端側部分および前記基端側部分の間に縫合針が把持される、内視鏡用持針器である。
In order to achieve the above object, the present invention provides the following means.
One aspect of the present invention includes a long flexible tube having flexibility, and a first gripping member and a second gripping member connected to the distal end of the flexible tube and capable of opening and closing each other. The first gripping member and the second gripping member each have a first inner surface and a second inner surface facing each other in a closed state in which the first gripping member and the second gripping member are closed, the first inner surface comprising: A pair of receiving portions parallel to each other and a groove formed between the pair of receiving portions, wherein the pair of receiving portions and the groove are oriented along the longitudinal axis of the flexible tube in the closed state. and the second inner surface has a protrusion facing the groove in the closed state and extending in a direction along the longitudinal axis, and a top surface of at least a portion of the protrusion extends relative to the longitudinal axis. The inclined surface has a distal portion facing the proximal side of the groove and a proximal portion facing the distal side of the groove, and the pair of receiving portions and a needle holder for an endoscope, wherein a suture needle is gripped between said distal portion and said proximal portion.
上記態様において、前記第１内面の先端部が前記凹凸面を有し、該凹凸面に対して前記一対の受け部が前記第２内面とは反対側にオフセットしていてもよい。
この構成によれば、一対の受け部上に配置された縫合針は、一対の受け部と凹凸面との間の段差によって、一対の受け部上に安定的にとどまる。したがって、操作者の意図に反して縫合針が一対の受け部から凹凸面側へ抜け出してしまうことを防ぐことができる。
In the above aspect, the tip portion of the first inner surface may have the uneven surface, and the pair of receiving portions may be offset from the uneven surface to the side opposite to the second inner surface.
According to this configuration, the suture needle placed on the pair of receiving portions stably stays on the pair of receiving portions due to the difference in level between the pair of receiving portions and the uneven surface. Therefore, it is possible to prevent the suture needle from slipping out of the pair of receiving portions to the uneven surface side against the intention of the operator.
操作部５は、可撓管２の内部を通るワイヤのような長尺の動力伝達部材によって、第２把持部材４と接続されている。操作者が操作部５に加えた力が動力伝達部材によって第２把持部材４に伝達されて第２把持部材４ｓが揺動することによって、把持部材３，４は開閉する。例えば、操作部５は、長手軸Ａに沿って延びるシャフト５ａと、シャフト５ａに沿ってスライド可能なスライダ５ｂとを有する。操作者は、スライダ５ｂを基端側へ牽引することによって把持部材３，４を閉じることができ、スライダ５ｂを先端側へ押圧することによって把持部材３，４を開くことができる。 The operating portion 5 is connected to the second gripping member 4 by an elongated power transmission member such as a wire passing through the flexible tube 2 . The gripping members 3 and 4 open and close when the force applied by the operator to the operating portion 5 is transmitted to the second gripping member 4 by the power transmission member and the second gripping member 4s swings. For example, the operating portion 5 has a shaft 5a extending along the longitudinal axis A and a slider 5b slidable along the shaft 5a. The operator can close the gripping members 3 and 4 by pulling the slider 5b toward the proximal side, and can open the gripping members 3 and 4 by pushing the slider 5b toward the distal side.
