PROBLEM TO BE SOLVED: To provide a surgical endoscope apparatus by which observation of a surgical site and surgical operation can be smoothly carried out by avoiding a soft endoscope and a surgical device from interfering in each other when using the surgical endoscope apparatus in a body in which the area near a front end side of a flexible tube part is formed softer than an area near the proximal end side.SOLUTION: In the flexible tube part 11, the area 11s near the distal end side is formed softer compared to the area 11h near the proximal end side from the flexible deforming part 11x formed in the middle of the flexible tube part 11, the length from the distal end of the flexible insertion parts 11, 12, 13 to the flexible the forming part 11x is formed longer than the length from the flexible the forming part 11x to the proximal end of the flexible insertion parts 11, 12, 13.COPYRIGHT: (C)2012,JPO&INPIT【課題】可撓管部の先端側寄りの領域が基端側寄りの領域より柔軟に形成された手術用内視鏡装置を用いる場合に、体内において軟性内視鏡と手術デバイスが干渉するのを回避して、手術部位の観察及び手術操作等をスムーズに行うことができる手術用内視鏡装置を提供すること。【解決手段】可撓管部11において、その途中に形成された可撓性変移部11xより基端側寄りの領域11hと比較して先端側寄りの領域11sの方が柔軟に形成されていて、可撓性挿入部11,12,13の先端から可撓性変移部11xまでの長さが、可撓性変移部11xから可撓性挿入部11,12,13の基端までの長さ以上に形成されている。【選択図】 図1
