PROBLEM TO BE SOLVED: To provide a maintenance method for an endoscope device capable of facilitating maintenance work such as repair or inspection without degrading the performance during normal use.SOLUTION: A second end 15b of a pipe member 15 is detached from a body part, and a jig 41 is connected to the second end 15b of the pipe member 15, detached from the body part. A leading-end composing part 4 is moved with respect to a flexible pipe part 3 in a direction from a basal end of the flexible pipe part 3 toward a leading end thereof, thereby exposing the leading-end composing part 4 out of the flexible pipe part 3, and maintenance work is carried out for at least part of the leading-end composing part 4. The pipe member 15 and the leading-end composing part 4 are pulled back into the flexible pipe part 3 by moving a maintenance jig 40 with respect to the flexible pipe part 3 in a direction from the leading end of the flexible pipe part 3 to the basal end thereof. After the maintenance work is carried out and the connecting portion between the maintenance jig 40 and the pipe member 15 is exposed from the basal end of the flexible pipe part 3, the pipe member 15 and the maintenance jig 40 are separated. The second end 15b of the pipe member 15 is attached to the body part 30 again after the pipe member 15 and the maintenance jig 40 are separated.COPYRIGHT: (C)2013,JPO&INPIT【課題】通常使用時の性能を損なうことなく、修理や点検等の保守作業が容易にできる内視鏡装置の保守方法を提供すること。【解決手段】管部材15の他端を本体部から取り外し、本体部から取り外された管部材15の他端15bに治具41を接続し、可撓管部3の基端から先端へ向かう方向へ可撓管部3に対して先端構成部4を移動させることにより先端構成部4を可撓管部3の外に露出させ、先端構成部4の少なくとも一部に対して保守作業を行い、可撓管部3の先端から基端へ向かう方向へ可撓管部3に対して保守治具40を移動させることにより管部材15及び先端構成部4を可撓管部3内に引き戻し、保守作業の後であって且つ保守治具40と管部材15との接続部分が可撓管部3の基端から露出された後に、管部材15と保守治具40とを分離し、管部材15と保守治具40とを分離した後に、管部材15の他端15bを本体部30に再取り付けする。【選択図】図8
