Document Type and Number:
WIPO Patent Application WO/2018/025437
Kind Code:
A1
Abstract:
An insertion device 1 is equipped with: an insertion portion 3 which has a prescribed degree of flexibility and is inserted into a body cavity of a subject, with a spiral tube 31 that can rotate about the longitudinal axis being detachably mounted thereto; and a drive source 72 for rotating the spiral tube 31. The section 25 of the insertion portion 3 to which the spiral tube 31 is mounted is formed by a structure which is configured such that even when subjected to an external force from the attempt by the body cavity wall in contact therewith to maintain a curved shape, the structure does not bend beyond an arbitrary bending angle such that rotation of the spiral tube 31 does not stop due to the driving force from the drive source 72.
