Claims (1)
- 非装着時には内視鏡本体が汎用の1チャンネル内視鏡としての通常使用を可能にするため着脱自在で、内視鏡の先端に装着して使用することにより内視鏡本体のチャンネルを介して挿入された切除具を用いずに切除・切開・剥離を可能にする独立した電気メス、ナイフもしくは高周波スネアを直接キャップ部の内側に取り付けたフードで、且つ、キャップ部の外側に取り付けられた電気メス、ナイフもしくは高周波スネアとなる金属線がキャッ プ部に開けられた斜孔を通ってキャップ部の内側に取り付けられ、これに連続するハンド ルを操作することにより、電気メス、ナイフもしくは高周波スネアの刃先の長さがキャップに対して水平方向に可変可能、つまり、最短時はキャップ内に留まり最長時はキャップ外に飛び出す長さに自在に出来、且つ、キャップ部の周在性を3分の1程度にカットし、狭細部への侵入を容易にした透明フード。
