The invention discloses a tissue clamping member of a linear
cutting anastomat and a nail granary of the tissue clamping member. The left side and the right side of a nail discharging surface of the nail granary are respectively provided with one column of barrier bars and barrier bulges, which are parallel to a knife pushing groove, and the front end part of a nail supporting surface of a nail supporting base of the tissue clamping member is provided with one row of semi-spherical concave holes along the left-right direction. During the use, the barrier bulges apply an acting force with the direction which is opposite to the advancing direction of a
cutting knife to the clamped
human body tissue, the two columns of barrier bars apply leftwards and rightwards acting forces which have the direction opposite to the advancing direction of the
cutting knife and face outside to the clamped
human body tissue, therefore the clamped tissue is stable and firm without slipping, wherein the left column of barrier bar applies to a leftwards acting force to the
human body tissue and the right column of barrier bar applies to a rightwards acting force to the human
body tissue, therefore, the clamped tissue is tightened, and the cutting knife carries out cutting more smoothly when advancing forwards.
