Description
Claims (2)
- 流体が流通可能に筒状に形成されるとともに患者に対して穿刺可能に形成された針本体と、該針本体と同方向に延びるように形成されるとともに該針本体の径方向の外側に並設され、患者に対して穿刺可能に形成された少なくとも一つの補助針と、前記針本体及び補助針のそれぞれを自己の軸心方向に往復動させるアクチュエータと、該アクチュエータの動作を制御するための制御手段とを備え、前記補助針には、前記針本体と対向する面とは反対側の面の少なくとも先端側に突起部が設けられ、前記制御手段は、少なくとも一つの補助針を軸心方向に押し出しつつ前記針本体を前記軸心方向に引き込んだ後、前記針本体を前記軸心方向に押し出しつつ前記少なくとも一つの補助針を前記軸心方向に引き込む動作を少なくとも一回行うようにアクチュエータを制御するように構成され、前記制御手段は、前記針本体及び前記補助針が穿刺する目的の位置に到達するまで、前記針本体及び前記補助針の往復動作を行うように前記アクチュエータの動作を制御することを特徴とする穿刺ユニット。
- 前記補助針は前記針本体の両側に設けられ、前記突起部は前記針本体の軸方向に複数設けられていることを特徴とする請求項1に記載の穿刺ユニット。
