摘要 |
A tissue capturing device (2) is formed by a substantially circular cylinder-shaped container (18), a filter member (19), and a lens member (20). The filter member (19) is provided with a substantially circular plate-shaped partitioning portion (31), and a circular column portion (32) that is formed substantially in the shape of a circular column and that is provided coaxially with a top surface (31a) of the partitioning portion (31). Recessed portions (36) that have a sufficient size to enable them to capture biological tissue A are formed n a circumferential wall portion (32b) of the circular column portion (32). Tissue capturing surfaces (37) are formed in bottom surfaces (36a) of the recessed portions (36). A plurality of micro through holes (38) that penetrate as far as a bottom surface (31 b) of the partitioning portion (31) are formed in the tissue capturing surfaces (37) of the recessed portions (36). A lens member (20) is also mounted on the container (18). The mounting position of the lens member (20) is a position that faces the tissue capturing surfaces (37). |
