Guide wire super-selective balloon catheter

Abstract

The invention discloses a guide wire super-selective balloon catheter by which a guide direction can be regulated. According to the technical scheme, a main body of the balloon catheter is a tubular body; two balloons are fixedly arranged on the outer wall surface of the tubular body; the balloons are eccentric bag bodies which are non-axial with the central axis of the tubular body, and the two balloons are different in eccentric direction; and two filling cavities, which communicate with the two balloons, are additionally formed in the tubular body. Compared with the prior technologies, the balloon catheter disclosed by the invention has the beneficial effects that the direction of a guide wire can be effectively and rapidly regulated to the entrance of a designated pipeline, so as to facilitate entry of the guide wire; therefore, an operation time is shortened and a guide wire super-selective success rate is improved.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a guide wire superselection balloon catheter. Background technique [0002] Biliary tract disease is a common disease in clinical practice. In the past, the treatment of biliary tract disease focused on surgical operations. In recent years, with the development of endoscopic technology, many diseases such as bile duct stones, benign and malignant bile duct strictures can be treated by endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic treatment of biliary tract diseases mainly includes three aspects: 1. Removal of bile duct stones; 2. Relief of obstructive jaundice caused by biliary or pancreatic tumors; 3. Relief of biliary strictures caused by benign biliary strictures such as iatrogenic biliary injury . The so-called endoscopic stone removal is generally carried out through a basket or balloon. The so-called endoscopic relief of obstructive jaundice caused...

AI Technical Summary

Problems solved by technology

However, there are clinical situations where selective intubation is difficult, that is, the guide wire repeatedly enters the non-target lumen, especially when the narrow lumen is located in an eccentric position, or for hilar bile duct strictures, the guide wire repeatedly enters a lumen other than the target lumen Cavity

Then there will undoubtedly be the following problems: 1. Prolonged operation time; 2. Reduced success rate; 3. Increased chance of surgical infection
