Description
Technical Field
The utility model relates to the field of surgical instruments, in particular to a supporting catheter for interventional operation.
Background
The incidence of coronary heart disease is higher and more, complex coronary artery diseases are more and more, the difficulty of the coronary artery interventional operation is high, and a guide tube needs to be strongly supported to finish the complex diseases, particularly twisted vascular diseases and chronic occlusive diseases. A good guide catheter must have good active and passive support capabilities, by which is meant the forward delivery capability of the catheter into the coronary vessel, often not being overly relied upon for fear of deep insertion of the catheter into the coronary vessel; the passive support capability is proportional to the diameter of the guiding catheter, the contact area between the catheter and the aorta, the friction between the catheter and the aorta wall, and the included angle between the catheter and the aorta. At present, all guide catheters in the market increase the support by changing the shape of the tip of the catheter, and the aortic root structure, coronary artery opening, size and the like of each patient are different, so that the situation that the tip of the guide catheter is displaced backwards and even breaks away from the opening of a blood vessel when a complex coronary artery interventional operation is carried out cannot be avoided, and the guide catheter is sometimes inserted into the coronary artery deeply for increasing the support, so that the blood vessel is damaged to cause the blood vessel to tear, thereby causing acute adverse events and even death.
The current operation support catheter has single function, and a support catheter for interventional operation is needed to solve the problem. An effective solution to the problems in the related art has not been proposed yet.
