    摘要： There is provided an endoscopic snare including: a flexible sheath 1; a cable 2 configured to slide in the sheath; a snare loop 3 connected to the cable 2, and projecting from or retracting into the sheath 1; a distal end tip 4 disposed in a distal end part of the sheath and retaining the snare loop 3; and a hand operating part for operating the snare loop 3 via the cable 2. One end of the snare loop 3 is attached to the distal end tip and the other end of the snare loop 3 is attached to a distal end of the cable. The snare loop 3 is expanded into a ring shape without a protruding portion when it is projected from the sheath 1, and is formed into an asymmetric shape where expansion is deviated to either side about an axis of the sheath.

    摘要： Disclosed is a snare instrument with a shaft area, a snare structure in a snaring area distally adjoining the shaft area, and a plurality of noose wires. The snare structure can be pulled closed, from an opened position with distally open snare, and has a plurality of flexible bending tubes which extend distally forwards and radially outwards in a radiating shape to form the snare, and of which the distal ends can be moved radially inwards towards each other so as to pull the snare structure closed. Each noose wire extends with a first base portion from the shaft area loosely through one of the bending tubes as far as the distal end thereof, from there with a noose arch to the distal end of the same or another bending tube, and from there with a second base portion loosely through the latter back to the shaft area. At least one of the noose wire base portions extends through each bending tube.
