Title:
CLIP REMOVAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/210364
Kind Code:
A1
Abstract:
The present invention reliably releases the grip of a clip main body on a biological tissue regardless of the orientation of the clip main body. A removal loop part 4 is pulled into a sheath 2, from a state in which a clip 10 is disposed within the opening of the removal loop part 4 so as to be further toward the sheath side than is a narrow part 41. Thus the narrow part 41 is used to move a tightening ring 12 to the rear side of the clip main body 11 so that the grip of the clip main body 11 on the biological tissue is released.
