摘要：
An endoscopic sleeve includes a tubular member from which extend spaced projecting elements. The projecting elements are bendable towards both proximal and distal directions of the tubular member. The force (insertion force) required to bend the projecting elements towards the proximal direction is less than a force (extraction force) required to bend the projecting elements towards the distal direction. An outer periphery of the projecting elements decreases as the extraction force increases.
