a support mechanism comprising a fixed connecting assembly and a drive assembly movable relative to the fixed connecting assembly; and
a clamp mechanism comprising closure members and capture portions which are in one-to-one correspondence with the closure members;
wherein each of the closure members comprises a closure connecting portion and a closure clamping portion in cooperation with respective one of the capture portions to clamp the tissue; and
wherein each of the closure connecting portions is provided with guide slots, each of the guide slots comprises, from a distal end to a proximal end thereof, at least a first slot portion and a second slot portion which is in communication with the first slot portion and has a radian smaller than that of the first slot portion, the fixed connecting assembly is provided with two pins at least partially located in the guide slots, respectively, and the fixed connecting assembly and the two closure connecting portions are arranged in such a manner that the two pins are slidable relative to the guide slots when the drive assembly moves relative to the fixed connecting assembly, so as to drive the two closure clamping portions of the clamp mechanism to move towards or away from each other.
