- 挿入部の先端硬質部に複数の超音波振動子を配列した電子走査式超音波トランスデューサを装着し、またこの超音波トランスデューサより後方位置に通路開口面部となし、この通路開口面部に処置具を斜め前方に向けて導出させる処置具導出口を形成し、さらにこの通路開口面部より後部側に斜め前方に向けて傾斜し、内視鏡観察手段を装着した観察手段装着用傾斜面部が形成され、前記内視鏡観察手段は、観察部とこの観察部の左右両側に設けた少なくとも2箇所の照明部とした超音波内視鏡において、
前記処置具導出口は、少なくともその一部が前記観察部の観察視野内に位置するように配置し、
前記通路開口面部の左右両側の部位を前記照明部からの照明光が遮られるのを抑制するように切り落として導光用退避壁部とし、
前記導光用退避壁部は、左右方向に関して、前記観察部寄りの前記照明部の端の内側に入り込んで形成されている
ことを特徴とする超音波内視鏡。 - 前記通路開口面部は、前記超音波トランスデューサの装着部より低所であって、先端硬質部の軸線と平行な方向の平面となし、この平面の左右を斜め下方に向けて傾斜させることにより前記導光用退避壁部とする構成としたことを特徴とする請求項1記載の超音波内視鏡。
- 前記通路開口面部は、前記超音波トランスデューサの装着部より低所であって、先端硬質部の軸線と平行な方向の平面となし、この平面を斜め前方に向けて傾斜するように切り落とすことにより前記導光用退避壁部とする構成としたことを特徴とする請求項1記載の超音波内視鏡。
