Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a hemostatic device for upper gastrointestinal bleeding. Background Art

[0002] Upper gastrointestinal bleeding is a common clinical symptom. There are many causes of upper gastrointestinal bleeding, among which bleeding caused by esophageal, stomach, duodenum, pancreas or bile duct diseases ranks first, among which peptic ulcer bleeding is the most common. Conventionally, endoscopic titanium clip closure hemostasis, submucosal injection hemostasis, APC electrocoagulation hemostasis, oral hemostatics can be used for hemostasis. About 80-90% of patients have successful endoscopic hemostasis. However, if there is a large ulcer bleeding on the posterior wall of the duodenal bulb, it is often difficult to stop bleeding, prone to repeated bleeding, and poor surgical and interventional treatment effects, because there are abundant blood vessels in the posterior wall of the duodenum, such as the hepatic artery and its branches, the right gastric artery, the superior pancreaticoduodenal artery, the gastroduodenal artery and the right gastric adventitial artery; when the ulcer on the posterior wall of the duodenal bulb erodes any of the above blood vessels or their branches, it will cause blood vessel rupture, resulting in massive bleeding, unclear vision and difficulty in stopping bleeding;

[0003] Endoscopic hemostasis is achieved by spraying liquid medicine locally. Its hemostatic mechanism is to cause local gastric wall spasm, contraction of blood vessels around bleeding, and promote blood coagulation, thereby achieving the purpose of hemostasis. However, when spraying liquid medicine, if the wound at the bleeding site in the patient's digestive tract is large, the sprayed liquid medicine is easily washed away by the blood, which affects the hemostatic effect. In addition, some wounds are in special locations, that is, there are places in the patient's digestive tract that require tissue folding. The folded tissue easily blocks the wound and affects the spraying of the liquid medicine.

[0004] Therefore, in order to solve the above technical problems, the utility model provides a hemostatic device for upper gastrointestinal bleeding. Utility Model Content
