OVERTUBE
Document Type and Number:
WIPO Patent Application WO/2019/022335
Kind Code:
A1
Abstract:
Provided is an overtube comprising: a gap maintaining protrusion part formed to protrude from the outer surface of the front end of the overtube such that even a lesion having a relatively large diameter, by which endoscopy cannot be performed, can be simply ligated and then incised; a band ligation part for ligating a lesion portion, by means of each band, at the outer surface of the front end of the overtube; and a guide cap provided so as to be attachable/detachable to/from the gap maintaining protrusion part, thereby allowing the front end thereof to focus the lesion portion to be ligated while protecting the band ligation part. Therefore, an operation of the lesion having the relatively large diameter, by which endoscopy cannot be performed, can also be simply, conveniently and quickly performed without incision.
