For example, in the course of radical operation of rectal cancer, before the intestinal canal at the far end of the tumor is cut off, the intestinal canal needs to be cleaned by anus enema, and the traditional method comprises the following steps: (I): the pre-cut upper edge is not blocked, and direct enema washing can cause washing liquid to pass through a tumor area, so that the risk of dropping tumor cells and planting proximal intestinal tracts can be caused, the tumor-free principle can not be achieved, and the risk of tumor intestinal tract planting and anastomotic stoma recurrence can be increased; and the content of the proximal intestinal canal continuously flows into the distal intestinal canal, so that the intestinal canal is difficult to be washed cleanly, the pollution of an anastomotic stoma is serious, and the risk of anastomotic leakage is increased. (II): the intestinal clamp is used for directly clamping the intestinal canal, and the intestinal clamp is limited in clamping force and difficult to last in the manner of clystering and cleaning the reserved intestinal canal, so that the risks of tumor intestinal canal implantation and anastomotic stoma recurrence are increased. (III): the hepatic portal occlusion band is knotted to occlude the intestinal canal, the risk of tumor intestinal canal implantation and anastomotic stoma recurrence is increased when the knot is too loose, and the risk of intestinal necrosis caused by insufficient blood supply at the intestinal canal occlusion part is increased when the knot is too tight; and the ligation mode often is difficult to reach the cross section, and the intestinal canal tissue at the ligation position forms folds, when using the cutting anastomat to cut the intestinal canal, easily makes the incisal edge uneven or forms the wedge incisal edge, leads to anastomosing the difficulty or anastomotic stoma tension increase, increases the risk that the anastomotic stoma leaks.

The effective clamping length of the tissue clamp, namely the size of the corresponding part of the clamping part 100 and the lower clamping part 300 in the closed state of the tissue clamp, can be set into different specifications according to years of clinical experience of all inventors, so that the effective clamping length of the tissue clamp can be conveniently selected according to the size of an intestinal canal or other tissues needing to be clamped and blocked of a patient in clinic, the specified tissue clamps with the effective clamping lengths of 50mm, 55mm, 60mm and 80mm can be set, and the clinical requirement can be met.

As shown in fig. 2, the upper end surface of the first closed end 120 is flush with the upper end surface of the upper clamping plate 110, and the lower end surface of the first closed end 120 is inclined upward from left to right; the second closed end 320 comprises a transition part 321 and a buckling part 322, the buckling part 322 is arranged at the top end of the transition part 321, at least part of the buckling part 322 protrudes to the left beyond the left end surface of the transition part 321, and the upper end surface of the buckling part 322 is arranged upwards from left to right; in the process of fastening the first closed end 120 to the second closed end 320, the lower end surface of the first closed end 120 is firstly attached to the upper end surface of the fastening part 322, so that the resistance to fastening the first closed end 120 downward can be effectively reduced, the upper end surface and the lower end surface of the first closed end 120 are both in fillet transition with the right end surface, and the resistance to fastening the first closed end 120 downward is further reduced; in the closed state of the tissue clip, the lower end surface of the fastening portion 322 is attached to the upper end surface of the first closed end 120.
When the puncture outfit is used, in order to reduce the operation difficulty of the tissue clamp in the abdominal cavity, the tissue clamp needs to be sent into the abdominal cavity in an unclosed state, the front end and the rear end of the left side of the connecting part 200 can be clamped by the separating forceps, the head part of the separating forceps is positioned in the clamping cavity 210, the lower end surface of the first closing end 120 is attached to the upper end surface of the buckling part 322 and then is plugged into the puncture outfit, and therefore due to the toughness of the connecting part 200 of the tissue clamp, the tissue clamp is in an open state after entering the abdominal cavity, and the tissue clamping operation is convenient; because the tissue clip needs to be sent into the abdominal cavity through the puncture outfit, the size of the circumscribed circle of the tissue clip along the length direction is smaller than the inner diameter of the puncture outfit under the state that the lower end surface of the first closed end 120 is attached to the upper end surface of the buckling part 322; preferably, the dimension of the circumscribed circle along the length direction of the tissue clip is less than 12mm in a state where the lower end surface of the first closed end 120 is fitted with the upper end surface of the fastening part 322.
As shown in fig. 1 to 3, the right end of the connecting portion 200 is provided with an opening, and above the opening, the connecting portion 200 is connected to the left end of the upper clamping portion 100; below the opening, the connecting portion 200 is connected to the left end of the lower clamping portion 300, the clamping cavity 210 formed by the shape of the connecting portion 200 is located on the left side of the opening, and at least a part of the separating forceps can extend into the clamping cavity 210, so that the separating forceps can control the tissue clip through the clamping connecting portion 200.
