Abstract
An endoscopic tissue collecting instrument includes an outer sheath that has an annular blade portion formed on the outer periphery of its distal end and which has a tissue retaining recess formed in the lateral side of an area close to the blade portion, and an inner needle that is fitted into the outer sheath to be capable of moving back and forth along the longitudinal axis and which has formed at the distal end a cutting blade for cutting off the tissue entering the tissue retaining recess and a needle tip pointed forward. The inner needle can be manipulated by the operator to move back and forth between two positions, one being where its distal end is drawn into the outer sheath such that it does not close the tissue retaining recess and the other being where it protrudes from the distal end of the outer sheath.
