Abstract
Disclosed is a gastrointestinal endoscope, including a deflectable direction-change tube, which consists of plural ring units, each having a hollow section. Adjacent ring units are spaced by a predetermined distance, having opposing end faces between which at least two integrally formed connectors are provided to connect the adjacent ring units together. An end of the deflectable direction-change tube is operatively coupled to a direction-change operation device and an opposite end coupled to a capsule endoscope clamping structure. At least one control wire extends through a bore of the deflectable direction-change tube and connected between the direction-change operation device and the capsule endoscope clamping structure. By operating an operation capstan to have the control wire pulling the capsule endoscope clamping structure, the deflectable direction-change tube is controlled to change direction, thereby changing direction of a capsule endoscope retained by the capsule endoscope clamping structure.
