- 鈍い遠位端が設けられる2つの遠位ハウジング部材を有しかつ2つの遠位ハウジング部材間に溝を形成する套管針ハウジングと、
套管針ハウジングの鈍い遠位端を遠位端方向に越える防護位置と、防護位置から内側に引込まれる安全位置との間で套管針ハウジング内で摺動可能な鋭利な先端部を有する刃組立体と、
防護位置にある刃組立体の先端部を越えて制動部材が延伸する突出位置と、防護位置にある刃組立体の先端部を露出させる引込位置との間で、套管針ハウジングに対して相対的に移動可能に套管針ハウジング内に配置される制動部材と、
刃組立体の先端部を防護位置に保持する刃係止部と、
制動部材に接続される係止解除部材と、
遠位端方向に制動部材を付勢するばね部材とを備え、
2つの遠位ハウジング部材間の溝内で刃組立体と制動部材とを摺動でき、
制動部材が組織に接触して突出位置から引込位置に内側に制動部材を摺動させると、防護位置にて制動部材から刃組立体の鋭利な先端部が露出して、先端部により組織を切断でき、
制動部材と組織との接触が解除されると、制動部材は、ばね部材により遠位端方向に引込位置から突出位置に移動し、
制動部材が引込位置から突出位置に移動すると、係止解除部材の移動による刃係止部と套管針ハウジングとの係合解除動作により、刃組立体を防護位置から安全位置に移動させることを特徴とする套管針組立体。 - 刃係止部は、刃組立体と套管針ハウジングとの一方に取り付けられかつ刃組立体と套管針ハウジングとの他方に着脱自在に係合し、刃組立体を防護位置に着脱自在に固定する請求項1に記載の套管針組立体。
- 刃係止部の係止部が套管針ハウジングの孔に係合するとき、係止解除部材は、刃係止部に選択的に係合され、
刃係止部は、係止解除部材の移動により套管針ハウジング又は刃組立体との係合を解除する請求項2に記載の套管針組立体。 - 刃組立体と套管針ハウジングとの一方に対して軸回転可能に刃係止部を取り付け、
刃組立体と套管針ハウジングとの他方に係合して套管針ハウジングに対する刃組立体の内側への移動を防止する係止位置と、防護位置から安全位置に刃組立体を内側に移動できる非係止位置との間で刃係止部を軸回転できる請求項2に記載の套管針組立体。 - 刃組立体に軸着される刃係止部に設けた係止部を係止位置で套管針ハウジングに係合させ、係止解除部材は、刃係止部に係合可能な爪を有する請求項4に記載の套管針組立体。
- 刃係止部に弾力を作用させて、刃係止部を付勢して套管針ハウジングに係合させるばねを設けた請求項5に記載の套管針組立体。
- ばねは、回転点と、回転点から延伸する第1のアームと、第1のアームとは異なる方向に回転点から延伸する第2のアームとを有し、
第2のアームを介してばねのばね作用を刃係止部に付与することにより刃係止部を付勢して、套管針ハウジングに係合させる請求項6に記載の套管針組立体。 - 係止解除部材の爪は、近位の表面と、遠位の角部とを有し、
刃係止部に対して係止解除部材を内側に移動する間、係止解除部材の近位の表面で刃係止部を案内し、遠位の角部を刃係止部に係合する請求項5に記載の套管針組立体。 - 制動部材の遠位端が套管針ハウジングの遠位端を越えて延伸する突出位置と、套管針ハウジングの遠位端に近接する引込位置との間で制動部材を套管針ハウジング内で摺動させる請求項1に記載の套管針組立体。
- 套管針ハウジングに対して刃組立体を摺動させて、套管針ハウジングの遠位端と制動部材の遠位端とを越える穿刺位置に鋭利な先端部を延伸させる請求項1に記載の套管針組立体。
- 制動部材の遠位端が套管針ハウジングの遠位端を越えて延伸する突出位置に向けて制動部材をばね部材により付勢し、
刃組立体が防護位置にありかつ制動部材が突出位置にあるとき、制動部材は、刃組立体の鋭利な先端部を遠位方向に越えて延伸する請求項1に記載の套管針組立体。
