TISSUE CAPTURING DEVICE, TREATMENT TOOL FOR ENDOSCOPE AND ENDOSCOPE
First Claim
1. A tissue capturing device comprising:
- a container that has an intake aperture that is connected to a fluid intake tube that transports biological tissue that has been collected by a treatment portion of a treatment tool for an endoscope and has been mixed with a liquid, and an outlet aperture that is connected to a fluid outlet tube that discharges the fluid that has been separated from the biological tissue;
a filter member that forms a screen between the intake aperture and the outlet aperture inside the container, and in which tissue capturing surfaces that are able to capture the biological tissue are formed on the intake aperture side, and in which a plurality of micro through holes that are in communication with the outlet aperture side and through which only the liquid is able to pass are formed in the tissue capturing surfaces; and
a lens member that is provided at a position inside the container where makes it possible to observe an enlargement of the tissue capturing surfaces.

Abstract
A tissue capturing device is formed by a substantially circular cylinder-shaped container, a filter member, and a lens member. The filter member is provided with a substantially circular plate-shaped partitioning portion, and a circular column portion that is formed substantially in the shape of a circular column and that is provided coaxially with a top surface of the partitioning portion. Recessed portions that have a sufficient size to enable them to capture biological tissue are formed in a circumferential wall portion of the circular column portion. Tissue capturing surfaces are formed in bottom surfaces of the recessed portions. A plurality of micro through holes that penetrate as far as a bottom surface of the partitioning portion are formed in the tissue capturing surfaces of the recessed portions. A lens member is also mounted on the container. The mounting position of the lens member is a position that faces the tissue capturing surfaces.
