Background technique

[0002] endoscopy, push enteroscopy and other microscopic look, descending duodenum nipple size, polyps and other targets are in tangential display, hard look into the whole picture of the lesion. Duodenum side mirror can clearly show the duodenal papilla size, polyps and other targets, have become the weapon of diagnosis and treatment, especially the descending duodenum duodenal disease, duodenal passage through ERCP more for the diagnosis and treatment of biliary and pancreatic disease wings, descending duodenum sphincterotomy, polypectomy, have already carried out in the clinical routine.

[0003] partial duodenal bleeding is a common complication of endoscopic therapy side. According to clinical statistics, ERCP sphincterotomy bleeding line rate and delayed bleeding rate of between 0.7% to 1.8%. Special, super-corrosive bile and pancreatic anatomy are important factors sphincterotomy bleeding is difficult to control. After the EPT is also a direct result of bleeding in patients with prolonged hospital stay, average hospital costs rise, and even some patients due to the failure to control bleeding EPT disability or death.

[0004] The hot biopsy forceps are commonly used instrument look endoscopic hemostasis in vascular accident Endoscopic forceps or lesions, then pass to coagulation current can achieve precise and effective hemostasis. Hot biopsy forceps endoscopic mucosal resection, endoscopic submucosal dissection has a strong practical value, but also an essential instrument of endoscopic mucosal resection. However, endoscopic workers found that hot biopsy forceps in use, the insulating layer prone to displacement, resulting in partial exposed help putter, so that the high-frequency surgical equipment with the use of the process is likely to have some non-essential burns, for doctors and patients increases risk of use.
