Claims (1)
- 底部側が内視鏡の処置具挿通チャンネルの入口部分に連通する状態に取り付けられる弾力性のある材料からなる樽状部材と、上記樽状部材の頭部側に係脱自在な弾力性のある材料からなる蓋状部材とが設けられ、処置具が通されることにより弾性変形して押し広げられるスリットを有する閉鎖膜が上記蓋状部材に形成された内視鏡の鉗子栓において、
上記樽状部材内の処置具が通る空間には、上記蓋状部材が上記樽状部材に取り付けられたとき上記閉鎖膜の裏面壁に当接して上記スリットを塞いだ状態になる舌片のみが上記樽状部材の内壁から内方に向かって突出形成され、
上記舌片は、上記蓋状部材が上記樽状部材に取り付けられると上記閉鎖膜の裏面壁により一端側を支点に押し下げられ、処置具が上記スリットを通って通過することによりさらに押し退けられた状態になることを特徴とする内視鏡の鉗子栓。
