Dual movable blade biopsy tool for multiple core biopsy

A biopsy system operable through an endoscope by a user comprising:

• a flexible sheath having a terminus with a distal chamber configured with a forward facing cutting edge comprising a plurality of movable blades, the plurality of movable blades including two counter rotating blades positioned perpendicular or beveled relative to a long axis of the distal chamber, each counter rotating blade of the two counter rotating blades configured to pivot from a separate corresponding axis;
• a manipulation end controllable by the user to plunge the forward facing cutting edge at a set depth or a depth selected by the user and to engage a cutting action by the plurality of movable blades at the set depth or the depth selected to acquire a plurality of specimens storable in the distal chamber;
• and
• a proximal chamber in fluid communication with the distal chamber, the proximal chamber configured to receive the plurality of specimens in an order and an orientation acquired upon exposure of a suction conveyed through the flexible sheath.
