Abstract

The invention discloses an integrated multifunctional double-balloon catheter, and relates to the technical field of medical instruments. The integrated multifunctional double-balloon catheter comprises a catheter body, a guide wire cavity is formed in the catheter body, a contrast agent outlet is formed in the end, close to the guide wire cavity, of the catheter body, the outer side of the catheter body is sleeved with a first radiopaque ring, a calculus removing balloon is installed on the catheter body, an air bag air outlet is formed in the calculus removing balloon and connected with the catheter body, and a dilation balloon is installed on the catheter body. According to the integrated multifunctional double-balloon catheter, the length of a narrow section of the digestive tract can be accurately measured during digestive tract dilation, the dilation effect can be evaluated through the calculus removing balloon at the front end, the calculus removing balloon and the dilation balloon are arranged on the catheter body, so that the catheter can be used for realizing conventional dilation and calculus removal operations in endoscopic retrograde cholangiopancreatography (ERCP), the manufacturing cost is lower than that of two instruments, and the cost performance is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated multifunctional double-balloon catheter. Background technique [0002] 1. Gastrointestinal stenosis is a very common lesion in clinical practice. There are many causes of gastrointestinal stenosis, such as tumor, anastomosis, IBD, etc., which may cause gastrointestinal stenosis. At present, the clinical treatment of gastrointestinal stenosis is mainly Dilation with a balloon or followed by stenting to relieve strictures in the digestive tract; [0003] currently existing problems: [0004] (1) The existing balloon dilation catheters in clinical practice cannot accurately measure the length of the stenosis of the digestive tract, so the inability to perform precise dilation may lead to poor dilation effect of the stenosis of the gastrointestinal tract; [0005] (2) After the existing dilation balloon completes the dilation of the stenosis of the digestive t...
