Closure clip and tissue clipping device comprising same

The utility model discloses a closing clip and a tissue clipping device comprising the closing clip. The closing clip comprises a limiting assembly, a closing clip body, a butt joint pipe and a pull rod. The limiting assembly comprises a sleeve, a first limiting part and a second limiting part, wherein the first limiting part and the second limiting part are connected with the sleeve. When the closing clamp body moves backwards, the casing pipe forces the closing clamp body to be in a clamping and closing state, and the first limiting part and the second limiting part limit the closing clamp body to move in the opposite axial direction. The butt joint pipe is located behind the first limiting part and the second limiting part, the rear end of the sleeve pipe is bent inwards to form a third limiting part connected with the butt joint pipe in a clamped mode, and the third limiting part can expand and deform under the action of external force so that the butt joint pipe can be separated from the sleeve pipe.
