摘要
An excisional device for either handheld car stereotactic table use may comprise an outer sheath that may comprise a distal scoopula shape configured to penetrate and/or cut tissue independently or in concert with work element(s). The articulable work element(s) may comprise articulable beak(s) and may be configured to translate and/or rotate at a first rate and to cut tissue in a direction implied by placement of the scoopula shaped outer sheath. A first helical element or equivalent assembly may be configured to transport tissue cut by the work element(s) and/or scoopula, may be co-axially disposed relative to the work element(s) and may be operative to rotate at a second rotation rate that is different than the first rate. A proximal sheath may be co-axially disposed relative to the work element(s) and the first helical element, and may be configured to rotate and actuate the work element(s).
