A tissue gripper, comprising:

• a connection frame, the connection frame comprising two connection pieces spaced apart and opposite to each other;
• two gripping arms, the two gripping arms respectively arranged on sides of the connection pieces, each of the gripping arms extending away from the other one of the gripping arms, and each of the gripping arms comprising a bending section connected to the corresponding connection piece, and a gripping section connected to the bending section and extending away from the corresponding connection piece, a width of the bending section being less than a width of the gripping section, and less than a width of the corresponding connection piece;
• wherein each of the connection pieces is connected to the corresponding bending section through a bent fixing piece, the fixing piece on the corresponding connection piece bending toward the other one of the connection pieces, and each of the bending sections bending away from the other one of the bending sections;
• wherein each of the bending sections includes a first end connected to the corresponding fixing piece, and a second end connected to the corresponding gripping section, a width of the bending section at the first end is greater than a width of the bending section at the second end;
• wherein the width of the bending section gradually decreases from the first end to the second end.
