Claims (3)
- 基部が内視鏡の処置具挿通チャンネルの入口部分に着脱自在に取り付けられる筒状の鉗子栓本体と上記鉗子栓本体の突端入口部に着脱自在に取り付けられる蓋体とが共に弾力性のある部材により形成されて、上記処置具挿通チャンネルに挿通される処置具によって押し開かれる閉鎖膜が上記鉗子栓本体と上記蓋体とに設けられた内視鏡の鉗子栓であって、
上記鉗子栓本体の外周面に円周溝が形成されて、上記鉗子栓本体の突端入口部寄りの部分の周囲を囲む状態に上記蓋体側から突設された環状壁の先端部分に、上記円周溝に対して係脱自在な内方突起が突出形成され、上記蓋体の内方突起を上記鉗子栓本体の外周面に沿わせて押し広げた状態に弾性変形させて上記内方突起を上記円周溝に係脱させるようにした内視鏡の鉗子栓において、
上記鉗子栓本体の外周面の上記円周溝より上記突端入口部寄りの部分が、縁部の面取り部分を除く全面において上記突端入口部側へ次第に径が細くなるテーパ状に形成されると共に、
上記蓋体の上記環状壁の内周面が、縁部の面取り部分を除く全面において上記鉗子栓本体の外周面の上記円周溝より上記突端入口部寄りの部分に沿うテーパ状に形成されて、
上記蓋体の内方突起が上記鉗子栓本体の円周溝に係合した状態になると、上記蓋体の環状壁のテーパ状の内周面が上記鉗子栓本体のテーパ状の外周面に密接することを特徴とする内視鏡の鉗子栓。 - 上記蓋体の内方突起が上記環状部の先端部分から全周にわたって内方に突出形成されている請求項1記載の内視鏡の鉗子栓。
- 上記蓋体の内方突起が上記鉗子栓本体の円周溝に係合した状態になると、上記蓋体の環状壁のテーパ状の内周面が上記鉗子栓本体のテーパ状の外周面に密接し、上記蓋体の閉鎖膜部分が上記鉗子栓本体の突端入口部の内周面に密接する請求項1又は2記載の内視鏡の鉗子栓。
