<p>PROBLEM TO BE SOLVED: To provide a double balloon type endoscope device that can be easily inserted into a deep gastrointestinal tract, and gives little pain to a person to be examined even when it is inserted into a deep part.SOLUTION: In a double balloon type endoscope device 10A having a fixing balloon 15 for an endoscope body 11 in an outer periphery on a distal end side of the endoscope body 11, and a fixing balloon 14 in an outer periphery on a distal end side of a sliding tube 12, a propelling balloon 16A for the endoscope body 11 is arranged between a distal end part of the sliding tube 12 and the endoscope body 11. The distal end side of the propelling balloon 16A for the endoscope body 11 is fixed on a proximal end side of the fixing balloon 15 for the endoscope body 11, and the proximal end side is fixed at the distal end of the sliding tube 12. A gas flow channel 13a for introducing gas inside the propelling balloon 16A of an insertion instrument and for sucking gas from the propelling balloon 16A is formed in the sliding tube 12 or the endoscope body 11.</p> |
