A material retrieval instrument, particularly for retrieving biological tissue. In one embodiment, the instrument comprises a cylindrical sheath having a distal end and a proximal end; an auger disposed in the sheath for rotation therein, the auger having a cutting blade disposed thereon, the cutting blade extending from the distal end of the sheath for engagement with tissue to be retrieved, the auger including a central longitudinal opening, the opening receiving an engaging member adapted to extend from the auger for engaging tissue to move the tissue into engagement with the cutting blade on the auger; the auger being rotatable in the sheath and comprising a conveyor for moving cut tissue longitudinally along the auger in the sheath to a tissue receiving reservoir; and a device for rotating the auger. In another embodiment, the instrument has an opening in a cylindrical surface of the sheath into which tissue to be excised can be fed for engagement with the cutting blade of the auger and subsequent removal.
A material retrieval instrument comprising: a cylindrical sheath having a distal open end and a proximal end; an auger disposed in the sheath for rotation therein, the auger having a cutting blade disposed thereon, the cutting blade extending from the distal open end of the sheath for engagement wit
