Background
In clinical operations, especially endoscopic operations, it is necessary to clamp blood vessels and other tissues before they are severed and then to perform severing and resection, and the main purpose of the surgical operation is to prevent digestive tract leakage such as hemorrhage and bile leakage. At present, commonly used ligation clips comprise an absorbable biological ligation clip and a Hem-o-lock plastic ligation clip (which are not absorbable), and the principle of clipping is to buckle the upper end and the lower end of the clip under the external force of a clip applier so as to achieve the purpose of clipping. The ligature clips with different sizes and models are selected according to the sizes of blood vessels or tissues.
At present, the problems that the tightening force is not controllable and the ligation process cannot be visualized when a clip applier is used for tightening a ligation clip exist; in addition, the main problems of using the ligation clip include that the ligation clip is fixed in size and type, target blood vessels and tissues to be clamped are different in size, so that incomplete clamping and partial clamping are inevitable, the clamping force is too large to cause 'tripping' and slipping after clamping, the large clip is small in size and slips or the operation visual field is occupied, the subsequent operation is limited, or the ligation clip is wasted due to inaccurate selection, and the ligation clip is also used for slightly larger tissues without corresponding ligation clips. The above problems, some occurring during surgery and some occurring after surgery, present immeasurable risks and damages to both the clinician and the patient. Secondly, the problem of firmness of clamping is that after the ligation clip used at present is clamped, due to the design structure, the ligation clip is not firmly buckled in use or has no multiple protection once the ligation clip is tripped after operation, so that the risks of the operation and the operation are obviously increased, and even the life safety is threatened.
