Description

technical field

[0001] The invention belongs to medical equipment, in particular to an intravascular catheter with a balloon for vascular surgery. Background technique

[0002] During surgery, in order to facilitate the operation, it is necessary to temporarily block the artery or vein. The medical device currently used is an intravascular balloon catheter, and its structure is to install one or two balloons at the open end of the catheter tube. , from the other end of the catheter tube, insert the trachea and blood vessel (also known as the lumen), which are respectively connected to the inner cavity of each balloon and the opening of the catheter tube, and block the artery or vein by intermittently filling the balloon blood flow. The arterial intravascular balloon catheter disclosed in Chinese patent ZL 02113689.0 adds a side hole on the catheter tube body and a delivery tube (also known as a lumen) that only communicates with the side hole on the basis of the above struc...
