Description
Technical Field
The invention relates to the technical field of minimally invasive medical technology and surgical instruments, in particular to a double-cavity calculus removing balloon.
Background
Common bile duct stones are common diseases and frequently encountered diseases in China, bile excretion can be unsmooth due to blockage of the common bile duct stones, complications such as acute cholangitis, obstructive jaundice and liver damage can be induced, manifestations such as shivering, fever, abdominal pain and jaundice appear, serious patients even cause shock, and long-term stone stimulation has the risk of bile duct cancer, so that the common bile duct stones are important diseases harmful to human health. The existing treatment scheme of the common bile duct calculus comprises the steps of laparotomy biliary tract exploration calculus removal, laparoscopic biliary tract exploration calculus removal, Endoscopic Retrograde Cholangiopancreatography (ERCP) calculus removal, Percutaneous Transhepatic Cholangiopuncture (PTCD), fistula expansion and Percutaneous Transcholangioscopy (PTCS) calculus removal, PTCD-approach duodenal papillary balloon dilatation balloon calculus removal and the like.
The biliary tract exploration requires general anesthesia, so the operation risk is high; PTCS is a long-term disease and the overall cost of treatment is high. The ERCP stone removal has many symptoms such as few contraindications, small wound, quick recovery, few complications and the like, and the choledocholithiasis is treated by adopting a scope ERCP approach at present. The ERCP is adopted to remove stones, two instruments, namely a stone removal saccule and a stone removal basket are generally adopted, wherein the stone removal basket is mainly used for treating stones with the diameter of more than 5mm, and the stone removal saccule is generally used for treating muddy stones, broken stones or stones with the diameter of less than 5 mm.
Most of the existing stone removal balloons are three-channel balloons, and the existing stone removal balloons comprise a guide wire channel, a balloon channel and an imaging channel. The partial saccule combines the guide wire channel with the radiography channel, a double-channel saccule appears, but the clinical use is more complicated, and the guide wire needs to be pushed out when the biliary tract radiography is carried out. At present, the conventional saccule adopts a guide wire channel penetrating through a saccule catheter, and the following problems and disadvantages exist in the clinical use process: 1. the operation of inserting the saccule is completed by an operator, and the operation of filling the saccule, imaging and inserting the guide wire is completed by an assistant. During the process of placing the saccule, the guide wire is easily placed into a peripheral bile duct by the saccule, so that pain of a patient is caused; in the process of pulling back and removing the calculus, the guide wire is easy to be pulled into duodenum, bile duct intubation is needed again, operation risk is increased, and operation time is prolonged; 2. the diameter of a clinically used guide wire is generally 0.89mm, the diameter of a guide wire channel is generally 1mm, and the guide wire channel and a balloon channel are added, so that a certain tube wall thickness is kept, the diameter of the balloon catheter is generally larger than 2mm, and when part of thin tube diameter or calculus is embedded, the balloon catheter cannot reach the position above the calculus, and in addition, the resistance of the balloon catheter is also increased by the balloon at the front section of the catheter.
