Clip refers to titanium clips, stomach bleeding on titanium clips is effective. Hemostasis titanium clip hemostasis is a hemostatic method that enters the bleeding site through the endoscopic biopsy hole and directly clamps the bleeding blood vessels and lesions visible to the naked eye. Its main purpose is to achieve hemostasis by clamping blood vessels and surrounding tissues. The principle of hemostasis is similar to that of surgical vascular suture or ligation, which is a mechanical method and does not cause coagulation, deformation and necrosis of mucosal tissues. This procedure has the advantages of small damage, fast hemostasis, low incidence of rebleeding, few complications, and precise efficacy. Hemostatic titanium clip technology is through the gastroscope biopsy hole into the hemostatic clip, under direct vision on the lesion to release the clip clamp hemostasis, for larger lesions can be released more than one clip, the operation is fast, convenient and safe. Titanium clips are prohibited for hemostasis in patients with variceal gastrointestinal bleeding, massive vomiting, shock and severe cardiopulmonary insufficiency, as well as diffuse mucosal bleeding. If the patient has gastric bleeding need to use titanium clips to stop bleeding, it is recommended to go to the regular hospital for consultation, clear examination, and actively cooperate with the doctor for treatment.
