Description

Serial-type stone balloon catheter of getting

Technical Field

The utility model belongs to the technical field of medical instrument makes, a minimal access medical surgery apparatus is related to for handle the minimal access surgery apparatus of inside and outside bile duct calculus of liver in the ERCP operation, specifically speaking are serial-type get stone sacculus pipe.

Background

Extrahepatic bile duct calculus is a common disease and frequently encountered disease in China, and the blockage of bile ducts by calculus can cause complications such as epigastric pain, high fever due to chills, obstructive jaundice, liver abscess and the like, and even cause infectious shock, cholestatic cirrhosis and the like, so that the life of a patient is endangered by serious patients.

The radical treatment method for the extrahepatic bile duct calculus comprises three treatment methods of surgery, intervention and endoscope treatment, wherein general anesthesia is required for the surgery, and the operation risk is high; the intervention treatment has small trauma, but has longer course of disease and higher total treatment cost. The Endoscopic Retrograde Cholangiopancreatography (ERCP) in the endoscopic technology has the advantages of small wound, quick recovery, relatively few complications and the like in treating the extrahepatic bile duct stones, and is the mainstream treatment scheme for treating the extrahepatic bile duct stones at present.

At present, consumable materials for ERCP (enterolith Electron cyclotron resonance) calculus extraction are mainly a calculus extraction balloon and a calculus extraction basket, small calculus is often extracted through the balloon, and most calculus with the diameter of more than 1cm is extracted through the basket. The lithotomy balloon for clinical application comprises two balloons, wherein one balloon is a fixed-diameter balloon, and the other balloon is a variable-diameter balloon. The diameter of the bile duct is only one, when the diameter of the bile duct is smaller than that of the balloon, the larger balloon presses the wall of the bile duct, so that the wall of the bile duct is easy to guide the blood to tear and bleed, and therefore, the diameter-variable balloon is selected in clinic. The balloon has only two controllable diameters, and if the diameter of the bile duct is larger than that of the balloon, small stones are easy to overflow through a gap between the balloon and the wall of the bile duct, so that the stones are taken out unsuccessfully; if the diameter of the bile duct is smaller than the minimum controllable diameter of the balloon, the bile duct wall is easy to be squeezed by the guide wire balloon to rupture and bleed, and at the moment, if the pressure in the balloon is reduced, the diameter of the balloon is not reduced along with the reduction of the pressure in the balloon due to the elasticity of the balloon, but the balloon is in a completely non-filling state, so that the calculus removal fails.
