Abstract

The invention provides a three-cavity balloon catheter which is used for solving the problem that a balloon catheter in the prior art does not have the cutting function. The three-cavity balloon catheter comprises a catheter head, the near end of the catheter head is connected with a balloon and a three-cavity tube, the three-cavity tube is connected with a handle outlet, the far end of the balloon is conical, the boundaries of the two sides of the balloon are each provided with a developing material tag block, the near end of the balloon is connected with the outer layer of the three-cavity tube, cavity channels of the three-cavity tube include the first cavity channel through which a guide wire can penetrate, the second cavity channel where medicaments can be injected, and the third cavity channel with a blood vessel knife, a knife storage area is arranged at the far end of the third cavity channel, and the blood vessel knife is arranged in the knife storage area. The three-cavity balloon catheter can break through intima to enter a true lumen in the interventional operation process, endangium of a false lumen can be cut open or broken through according to requirements, a lesion section lumen is cut for passing, and therefore repeated withdrawing and repeated puncturing of the balloon catheter can be avoided.

Description

technical field [0001] The invention relates to the field of interventional medical equipment, in particular to a three-chamber balloon catheter. Background technique [0002] Currently, balloon catheters are used in interventional procedures to balloon narrowed arteries to improve tissue blood supply. For the balloon catheter, the proximal steel tube is made of medical stainless steel tube, and the end of the coaxial dirty tube is made of high-density polyethylene. When using a balloon catheter to dilate the lesion, the balloon catheter is sent to the lesion first, and then the high pressure resistant balloon is pressurized and expanded. After the femoral artery sheath is inserted during the operation, heparin sodium is injected intravenously to prevent intraoperative vasospasm. , before the balloon is withdrawn, inject nitroglycerin into the blood vessel lumen. [0003] However, in the process of interventional surgery, sometimes the guide wire catheter cannot enter the ...
