ADJUSTABLE THROW PERCUTANEOUS NEEDLE

摘要

A device for collecting a tissue sample includes an outer needle extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough. The device also includes an inner needle extending longitudinally from a proximal end to a distal end and including an opening extending laterally in and along a length thereof. The inner needle is sized and shaped to be slidably received within the lumen of the outer needle and movable relative thereto between an insertion configuration, in which the opening is covered by the outer needle, to a tissue collecting configuration, in which the opening is exposed. In addition, the device includes a handle assembly for adjusting a throw length of the inner needle relative to the outer needle.
