Problems solved by technology

[0002] Biliary stones are a common disease in surgery. Stones in the common bile duct can cause biliary obstruction secondary to jaundice, cholangitis and even pancreatitis, which is life-threatening. Surgery is the only way to treat this disease. Choledochoscopic stone removal is currently the most commonly used surgical treatment for biliary stones. A kind of method, in this process, usually place the fiber choledochoscope along the biliary incision, after discovering the stone, use the stone removal net to take out the stone, but the stone removal effect of the prior art is not ideal, thus resulting in long operation time, causing harm to the patient Therefore, we propose a negative pressure suction biliary stone removal aid
