Abstract

The invention provides a double-cavity calculus removing balloon. The calculus removing balloon comprises a catheter body, a balloon part arranged at the front end of the catheter body and a handle part arranged at the rear end of the catheter body. A first channel and a second channel are formed in the catheter body, the first channel and the second channel are respectively connected to a first handle and a second handle, the first channel is used for inflating the balloon part, the second channel is used for injecting a contrast medium for cholangiography, the front end of the balloon part is provided with a head part, the head part is a single-channel tube, and the tube wall of the tube is provided with a guide wire through hole for a guide wire to pass through. During use, the tail endof the guide wire sequentially penetrates through the front end of the head part and the guide wire through hole, the contrast medium is injected through the second handle for cholangiography, and the balloon is filled with gas injected through the first handle for calculus removal. According to the invention, a guide wire side hole is formed in a catheter in front of the balloon, the balloon anda body part are not provided with guide wire channels but only provided with an injection channel and a balloon channel, and therefore a balloon bile duct can be made thinner, and the requirements ofa manufacturing process and materials are lower.

Description

Technical field

[0001] The invention relates to the technical fields of minimally invasive medical technology and surgical instruments, in particular to a double-cavity stone extraction balloon. Background technique

[0002] Common bile duct stones are a common disease and frequently-occurring disease in my country. Blocking the common bile duct by stones can lead to poor bile excretion, which in turn induces complications such as acute cholangitis, obstructive jaundice, liver damage, chills, fever, abdominal pain, and jaundice. Severe cases can even lead to shock. Long-term stone stimulation has the risk of bile duct cancer, which is an important disease endangering human health. The current treatment options for choledocholithiasis include open bile duct exploration, laparoscopic biliary exploration, endoscopic retrograde cholangiopancreatography (ERCP) stone retrieval, percutaneous transhepatic cholangiography (PTCD) + fistula dilation + percutaneous transhepatic biliary tract ...
