- 観察窓等が配置された先端部本体が遠隔操作により屈曲する湾曲部の先端に連結されて、上記湾曲部を外装被覆する弾力性のある湾曲部外皮チューブの先端部分が上記先端部本体の外周面に緊縛糸で緊縛固定され、さらに上記緊縛糸が外表面に露出しないように上記緊縛部の外面に接着剤が塗布された内視鏡の挿入部において、
上記緊縛部の先側に隣接して上記先端部本体の外周部の全周に、底面が上記緊縛糸と並ぶ程度の深さの接着剤充填溝が形成されて、その接着剤充填溝の先端壁が上記底面に対して鈍角をなす角度で上記底面から立ち上がった斜面状に形成され、
上記湾曲部外皮チューブの先端の上記緊縛糸で緊縛された窄まった部分と上記先端部本体の接着剤充填溝とにより一つの凹溝が上記挿入部の全周にわたって形成されて、上記接着剤が、その凹溝の外周側開口面より外方に突出することなくその凹溝内全体に充填され、
上記接着剤充填溝の先端壁の外縁部分付近が、上記先端部本体の外周部において径方向に盛り上がった形状に形成されて、それより先端寄りの領域の上記先端部本体の外周面が全体として上記接着剤充填溝の先端壁の外縁部分より細い一定の径に形成されていることを特徴とする内視鏡の挿入部。
