Balloon dilatation tube for the pediatric hepatobiliary surgery department

Abstract

The invention, which belongs to the field of pediatric surgery, discloses a balloon dilatation tube for the pediatric hepatobiliary surgery department. The balloon dilatation tube comprises a catheterbody, a balloon assembly, a catheter reinforcer, a catheter seat, and a perfusion inner tube arranged in the catheter body. The perfusion inner tube penetrates the two ends of the catheter body. Theballoon assembly is installed at one side of the catheter body; one end, away from the balloon assembly, of the catheter body is connected with the catheter seat through the catheter reinforcer. A main channel and an auxiliary channel are respectively arranged on the catheter seat and are provided with second inflation inlets; a first inflation inlet is formed in the end, away from the balloon assembly, of the perfusion inner tube; a medicine injection opening is formed in one side of the first inflation inlet; and the outer end of the medicine injection opening penetrates the exterior of theperfusion inner tube. In addition, the balloon dilatation tube also includes an inflation device. The balloon dilatation tube having the high functionality is capable of reducing the pain and psychological burdens of a patient greatly; medicine treatment can be carried out, liquid medicine enters the body of a patient in a powder mist mode, and the powder adheres to the infection focus position, so that the medicine treatment is realized.

Description

technical field [0001] The invention relates to the technical field of pediatric surgery, in particular to a balloon dilation tube for pediatric hepatobiliary surgery. Background technique [0002] Hepatolithiasis in children is not only rare, but also due to the coexistence of pathological changes in the intrahepatic and extrahepatic bile ducts, the treatment is more complicated, and the balloon dilatation catheter is a kind of tube used to expand the human digestive tract or other pipelines in the human body for treatment. In the modern society where the medical technology is more developed, the balloon dilatation catheter, as a kind of medical tool, is also relatively well-developed, from the material to the specific structure. Balloon dilation catheters are also required. Although the current balloon dilation catheters are relatively sound, they are still functionally single, such as [0003] 1. The expansion tube cannot administer drugs to the patient, which brings a l...

Problems solved by technology

[0002] Hepatolithiasis in children is not only rare, but also due to the coexistence of pathological changes in the intrahepatic and extrahepatic bile ducts, the treatment is more complicated, and the balloon dilatation catheter is a kind of tube used to expand the human digestive tract or other pipelines in the human body for treatment. In the modern society where the medical technology is more developed, the balloon dilatation catheter, as a kind of medical tool, is also relatively well-developed, from the material to the specific structure. Balloon dilation catheters are also required. Although the current balloon dilation catheters are relatively sound, they are still functionally single, such as

[0003] 1. The expansion tube cannot administer medicine to the patient, which brings a lot of inconvenience to the need for powder drug treatment

[0004] 2. The inflated balloon has to bear a certain pressure in the bile duct, and the balloon is easy to rupture, which brings difficulties to the operation. At this time, it is difficult to push the catheter back and forth, causing pain to the patient and increasing the psychological burden
