Patent ID: 10335185

Abstract:
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.
