γγIn recent years, the application of endoscopic hemostatic clips has become the most effective and clinically useful method for the non-surgical treatment of acute gastrointestinal bleeding in critically ill patients because of its less invasive nature, faster hemostasis, lower incidence of rebleeding, fewer complications, and more precise efficacy. Gastrointestinal bleeding is a common clinical condition. Endoscopic hemostasis has increasingly become one of the preferred methods of hemostasis. And the current hemostatic methods include: drug spray hemostasis, local drug injection hemostasis, laser coagulation, electrocoagulation, microwave hemostasis, hemostatic clip hemostasis, etc. For bleeding caused by the exposure of blood vessels on the ulcer surface, if the bleeding vessels are at the edge of the ulcer and the surrounding necrotic tissue is less, the bleeding site can be firmly clamped with a clip, and the hemostatic effect is rapid and satisfactory. For bleeding stumps during and after polyp electrosurgery, because they are surrounded by normal tissues, hemostatic clips can firmly clamp the bleeding stumps and normal tissues together, which greatly reduces the risk of endoscopic treatment of gastrointestinal polyps.γ
