Claims (1)
- 基部が内視鏡の処置具挿通チャンネル(3)の入口部分に取り付けられる鉗子栓本体(11)と、その鉗子栓本体(11)に対し被さった状態に着脱自在に取り付けられる略キャップ状の蓋体(12)とが共に弾力性のある材料により形成されて、上記処置具挿通チャンネル(3)に挿通される処置具により押し開かれる閉鎖膜(16,17)が上記鉗子栓本体(11)と上記蓋体(12)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(11)の外周部の周方向に外周溝(21)が形成されて、その外周溝(21)に対して係脱自在な環状の内方突起(23)が上記蓋体(12)の開口端部に内方に向けて突出形成されると共に、上記鉗子栓本体(11)の外周面が頂部(11a)側から基部側へ次第に径が窄まる逆テーパ状に形成されて、その部分と上記外周溝(21)との間の部分に上記頂部(11a)より外径の大きな大径部(26)が形成され、
上記大径部(26)の両端面のうちの頂部側端面が円錐面(31)状に形成されると共に、上記蓋体(12)が上記鉗子栓本体(11)に取り付けられる際には、上記蓋体(12)の内方突起(23)が、上記鉗子栓本体(11)の円錐面(31)に当接してから上記太径部(26)を乗り越えて上記外周溝(21)に係合するように構成された内視鏡の鉗子栓において、
上記蓋体(12)が上記鉗子栓本体(11)に取り付けられる動作の途中において上記円錐面(31)に当接する上記内方突起(23)の端面が円錐孔面(32)状に形成されて、その円錐孔面(32)の頂角(δ2)が、上記鉗子栓本体(11)の大径部(26)の頂部側端面に形成された円錐面(31)の頂角(δ1)より大きく形成されていることを特徴とする内視鏡の鉗子栓。
