摘要：
An excisional device may comprise a work element configured to rotate at a first rotation rate and comprising a first and a second articulable beak configured to cut tissue. A first helical element, configured to transport tissue cut by the first and second articulable beaks, may be co-axially disposed relative to the work element and operative to rotate at a second rotation rate that is different than the work element. A proximal sheath may be co-axially disposed relative to the work element and the first helical element, and may be configured to rotate the work element and to actuate the first and second articulable beaks.
