    摘要: An interlocking nested cannula set (231) has a plurality of telescoping tubes cooperatively configured and dimensioned to reach a target location relative to an anatomical region. Each tube has a pre-set interlocking shape. A nesting of an inner tube (30) within an outer tube (40) includes a gap (50) between the tubes (30, 40), which interlock within the gap (50) to limit rotation of the tubes (30, 40) relative to the gap (50). The interlocking shapes of the tubes (30, 40) may be identical or different. Examples of the interlocking shapes of a polygonal interlocking shape, a non-circular closed curve interlocking shape, a polygonal-closed curve hybrid interlocking shape and a keyway interlocking shape.

    摘要: Methods and systems for nested cannula configuration involving helical tubes (40). The nested cannula (60) includes a plurality of telescoping tubes cooperatively configured and dimensioned to reach a target location relative to an anatomical region through a set of arcs (11, 21, 41) including one or more helical arcs (41) with each arc being determined between a point associated with the anatomical region and the target location. In particular, a three-dimensional image (51) of the anatomical region is utilized to generate the series of arcs, which in turn are utilized to calculate a pathway (53) that is utilized to configure and dimension the tubes.
