The invention discloses an endoscope device and a bidirectional elastic flexible body for controlling the bending of the flexible body, wherein the endoscope device for controlling the bending of the flexible body comprises a swinging head mechanism, a support part and, at least, a bidirectional elastic flexible body and at least a line body.The head swinging mechanism is provided with an inner viewing lens group and the first and second connecting parts of the phase plane pair.The supporting part faces the swinging head mechanism, and the supporting part is provided with a first holding space.The bi-directional elastic flexible body is positioned between the head swinging mechanism and the support part and has a plate body, a first joint part and a second joint part.The first and second sides of the plate body can be bent. The first joint is at one end of the plate body, and the second joint is at the other end of the plate body.The line body connects the first and second connecting parts and passes through the first holding space.By pulling one end of the wire body, the plate body is bent towards the corresponding first or second side.本發明揭露一種控制可撓體彎曲之內視鏡裝置及雙向彈性可撓體，其中控制可撓體彎曲之內視鏡裝置係包含一擺頭機構、一支撐部及、至少一雙向彈性可撓體及至少一線體。擺頭機構具有一內視鏡頭組以及相面對之第一、第二連接部。支撐部面對擺頭機構，支撐部內具有第一容置空間。雙向彈性可撓體位於擺頭機構及支撐部間且具有板體、第一接合部及第二接合部。板體之第一面及第二面可彎折，第一接合部位於板體一端，第二接合部位於板體另一端。線體連接第一、第二連接部且穿越第一容置空間。其中藉由拉動線體之一端，使板體朝相對應之第一面或第二面彎折。
