Claims (5)
- 可撓性チューブと、該チューブの中を通る可撓性ワイヤと、該ワイヤの先端に設けられた、周面に溝を有する細胞採取針と、手元側から該ワイヤを押し引きして、該針を該チューブの先から出没させるための操作器からなる穿刺型細胞診器具において、該操作器が、 該チューブの後端から引き出した該ワイヤを固定するための、該操作器ボディに前後に移 動できるように支持されたピストンと、該操作器ボディに前後に移動自在に支持されたラ ックと、該ラックと噛合する、該操作器ボディに回転自在に支持されたピニオンと、該ラ ックを所定の方向に所定の範囲動かすと、該ピストンが前進し、次いで後退して元の位置 に戻るよう、該ピニオンの回転運動を該ピストンの前後運動に変換する運動変換手段から 構成されることを特徴とする穿刺型細胞診器具。
- 該可撓性チューブの先に中空針を延設し、該細胞採取針が該中空針の先から出没するようにした請求項1に記載の穿刺型細胞診器具。
- 該運動変換手段が、該ピストンに設けられた、前後方向に垂直に延びる溝と、該溝に係合する、該ピニオンに設けられたピンからなる請求項1または2に記載の穿刺型細胞診器具。
- 該ピストンに、該ワイヤの後端に取り付けられたエンドピースを固定するための固定点が前後に間隔を存して複数設けられている請求項1、2または3に記載の穿刺型細胞診器具。
- 該ラックがいっぱいに前進または後退した位置に来ると、該ラックを動かないように保持するストッパが働くようにした請求項1、2、3または4に記載の穿刺型細胞診器具。
