1. A device, comprising:
a work element, configured to cut tissue and formed from a single tube of material and comprising a plurality of cuts to define, at a distal end of the single tube of material, at least one articulable beak and, at a proximal end of the single tube of material, the plurality of cuts further defining a helical resilient section that is configured to bias the at least one articulable beak in an open configuration and that, when compressed, causes the at least one articulable beak to assume a closed configuration;
a flexible tube having a distal end co-axially coupled to the helical resilient section of the work element;
a handle comprising an actuating lever that is coupled to a proximal end of the flexible tube and that is operative to selectively cause the at least one articulable beak to assume an open or closed configuration by acting upon the flexible tube.
