Abstract

The invention provides a three-lumen balloon catheter to solve the problem that the balloon catheter does not have the cutting function in the prior art. A three-lumen balloon catheter, including a tube head, the proximal end of the tube head is connected to the balloon and the three-lumen tube, the three-lumen tube is connected to the outlet of the handle, the distal end of the balloon is tapered, and the boundaries on both sides of the balloon are respectively A developing material marking block is installed, and the proximal end of the balloon is connected to the outer layer of the three-lumen tube. The lumen of the three-lumen tube consists of a first lumen for the guide wire to pass through and a second lumen for drug injection. It is composed of a third cavity with a vascular knife, a knife storage area is provided at the far end of the third cavity, and the vascular knife is arranged in the knife storage area. The three-lumen balloon catheter can break through the intima into the true lumen during the interventional operation, incise or break through the intima of the false lumen as needed, and cut through the lumen of the diseased segment to avoid repeated withdrawal and puncture of the balloon catheter.

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 , before the balloon is withdrawn, inject nitroglycerin into the blood vessel lumen.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 ...
