ABSTRACT:
A device for picking up tissues comprises a flexible outer sheath, an extension wire extending through the outer sheath, a connector fixed by one end of the wire and having an outer diameter larger than the inner diameter of the outer sheath for abutting on one end of the outer sheath, a tissue picking-up section connected to said one end of the wire by the connector, a wire holding section for holding the other end of the extension wire and receiving the other end of the outer sheath, a chamber formed in the wire holding section, and a compression spring disposed in the wire holding section for resiliently urging the other end of the outer sheath toward the tissue picking-up section. The device is inserted into an endoscope disposed in a body cavity, and its outer sheath can be easily bent according to the shape of the body cavity.
