Abstract

Disclosed is a bendable multifunctional coronary artery guiding catheter. The bendable multifunctional coronary artery guiding catheter comprises a shell, a rubber sleeve, a composite tube, a right-handed and left-handed internal thread guide tube, a left-handed half-thread tension mechanism and a right-handed half-thread tension mechanism. The bendable multifunctional coronary artery guiding catheter with the novel structure can easily reach coronary artery ostia and be deeply inserted into coronary arteries by adjusting the direction of the guiding catheter, super-large active supporting force can be provided during treatment of complicated cases, left and right coronary artery arteriography and PCI can be completed through one guiding catheter, and repeated catheter replacement is not needed during an operation.

Description

technical field [0001] The invention relates to a medical device, in particular to an adjustable and bendable multifunctional coronary artery guiding catheter. Background technique [0002] At present, different coronary guide catheters can be selected according to the characteristics of the aortic arch, the position and direction of the coronary ostium, and the selection of support force, but these catheters are all placed at the coronary ostium or near the end. Even so, stents or balloons in severe tortuous or calcified vessels still cannot lesion smoothly, or traditional guiding catheters cannot provide sufficient supporting force. Contents of the invention [0003] The object of the present invention is to provide an adjustable and multifunctional coronary artery guiding catheter with simple structure and convenient operation, which can be inserted deep into the coronary artery by adjusting the direction of the guiding catheter. [0004] In order to solve the above te...
