Claims (3)
- 中間にL字状に屈曲した屈曲部を有し先端部が下方に向って屈曲した中空の針部と、針部の後端に設けられたハブと、針部の先端を収容自在な可撓性のチューブ体とを備える留置針において、
ハブには前方へ延びて針部の後端部を覆う筒状部が設けられ、筒状部には前後方向に延びるスリットが設けられ、
チューブ体は、針部を摺動自在に内挿すると共に、初期状態では筒状部内であって針部の後端側に位置し、
チューブ体の後端には、筒状部内で針部の屈曲部と後端との間を摺動自在な摺動筒が設けられ、
摺動筒には、筒状部のスリットから外方へ露出する操作レバーが設けられ、
チューブ体の上側外面に前後方向に間隔を存して複数の切込部が設けられ、
操作レバーを筒状部のスリットに沿って前進させることによりチューブ体が針部の先端を収容することを特徴とする留置針。 - 請求項1記載の留置針において、チューブ体は先端を閉塞する閉塞部を備え、チューブ体の先端部にはチューブ体の中心軸線に対して偏心させた位置に孔部が設けられ、この孔部からチューブ体の先端を湾曲させるようにして針部の先端部が露出し、操作レバーを筒状体のスリットに沿って前進させ針部の先端がチューブ体の孔部から抜け出したときに、針部の先端がチューブ体内に収容されることを特徴とする留置針。
- 請求項1又は請求項2記載の留置針において、操作レバーを筒状体のスリットに沿って前進させ、チューブ体内に針部の先端を収容したときに、操作レバーの後退を阻止する後退阻止機構を備えることを特徴とする留置針。
