ENDOSCOPIC SLEEVE Russian patent published in 2018 - IPC A61B1/00 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to the endoscopic sleeve devices. Device comprises a tubular member from which extend a plurality of spaced projecting elements, said projecting elements being bendable towards both proximal and distal directions of said tubular member. Wherein a force (insertion force) required to bend said projecting elements towards the proximal direction is less than a force (extraction force) required to bend said projecting elements towards the distal direction and an outer periphery of said projecting elements decreases as the extraction force increases. In this case, the projecting elements comprise sets of protruding elements, each of which is spaced apart from each other along an axis. In this case, the radius of the sets of protruding elements extending from the tubular member, gradually increases as you move in the proximal direction along the length of the tubular element, or adjacent sets of projecting elements comprise a more proximal set of projecting elements and a more distal set of projecting elements, and the more proximal set of projecting elements is hindered in bending towards said distal direction by abutting against the more distal set of projecting elements.

EFFECT: device of an endoscopic sleeve is proposed.
