Claims (4)
- 長手方向の一端に第1の針先を有する筒状の外針と、
先端に形成された第2の針先と、先端の前記第2の針先に向かって傾斜する傾斜面と、前記傾斜面よりも基端側の側面に生体組織を採取するためのノッチが形成されたノッチ部とを有し、前記外針に対して該外針の長手方向に進退自在に挿通される柱状を成す内針と、
前記外針および前記内針をそれぞれ独立して長手方向にスライドさせる移動機構であって、該移動機構が移動することによって、前記外針及び前記内針が、前記第2の針先が前記第1の針先よりも先端側に位置する第1の状態と、前記第1の針先の長手方向における位置が前記内針の傾斜面の基端よりも先端側に位置するとともに前記第1および第2の針先間の距離が前記第1の状態における針先間の距離より短い第2の状態と、の間を遷移するように、前記内針の先端方向へのスライド可能な最大距離よりも前記外針の先端方向へのスライド可能な最大距離の方が大きく設定された移動機構と、
を有することを特徴とする生検針。 - 前記第1の状態は、長手方向における前記第1の針先の位置が前記内針の傾斜面より基端側であることを特徴とする請求項1に記載の生検針。
- 前記第1の状態は、前記外針の内部に前記ノッチ部の少なくとも一部が位置することを特徴とする請求項1に記載の生検針。
- 前記内針は、円柱状であることを特徴とする請求項1に記載の生検針。
