Abstract: An instrument for collecting tissue from a body cavity includes a hollow tubular body having a tubular wall. The hollow tubular body can collect material from a body cavity in a coring mode or an aspiration mode. The tubular wall defines a passage that extends from a proximal end portion of the tubular body to a distal end portion of the tubular body. A middle section of the tubular body includes an articulating section that allows the middle section to articulate relative to the proximal end portion. The distal end portion includes at least one suction port extending from an outer wall surface to an inner wall surface of the tubular wall. The suction port provides a path of fluid communication between the outer wall surface and the passage for drawing in tissue from a body cavity when the tubular body is connected to a source of negative pressure.

Abstract: A body tissue collection instrument having: a rigid shaft; an articulating shaft extending from the rigid shaft; a core drill attached to the end of the articulating shaft; a central passage defined within the rigid shaft, the articulating shaft and the core drill, the central passage extending continuously from the proximal rigid shaft end to a distal opening located on a longitudinal axis of the core drill at the distal end of the core drill; and a flexible cannula located within the central passage along the articulating shaft. The articulating shaft has interlocking segments with a gap between each adjacent pair of segments. The flexible cannula has a sidewall configured to engage an inner wall surface of the central passage defined by the plurality of interlocking segments to seal the gaps between adjacent pairs of the interlocking elements.
