1. A medical instrument for removing specimens of tissue from a patient'"'"'s body during a minimally invasive surgical procedure, comprising:
- (a) an elongated housing having a distal end and a proximal end;
(b) an inlet to the housing located near the distal end of the housing;
(c) two rotary elements supported directly or indirectly by the housing, one of which is located near the distal end of the housing and the other of which is located closer to the proximal end of the housing;
(d) an elongated member selected from the group comprising a flexible member and a bendable member, wherein the elongated member extends around the rotary elements and wherein the elongated member may be made to move in a desired direction by an activation mechanism; and
(e) a plurality of anvils located on the elongated, such that when the elongated member is moved, the anvils, in turn, rotate past the at least one opening, and such that when tissue is located in the inlet at least a portion of the tissue is removed by the interaction of the anvil with an edge of the housing, wherein the removed tissue is transported within the housing away from the inlet toward the proximal end of the housing.

Abstract
Some embodiments of the invention provide an instrument for mechanically removing segments of tissue from a patient during a minimally invasive surgical procedure. An exemplary instrument provides an inlet for receiving tissue a mechanism for cutting away received tissue and for simultaneously moving the cut away tissue away from the inlet to allow additional material to enter the inlet for removal wherein multiple specimens can be captured and eventually removed from the patient'"'"'s body without the need of removing the instrument after each capture.
