Intervening and closuring partitioning catheter for congenital heart disease ventricular septal defect surgery

Abstract

The invention relates to an intervening and closuring partitioning catheter for a congenital heart disease ventricular septal defect surgery. The intervening and closuring partitioning catheter comprises a soft head and a catheter body. The catheter body comprises a catheter head end, a head-adjacent end and a catheter tail end. The front end of the head-adjacent end is connected to the catheter tail end, and the rear end of the head-adjacent end is bent reversely and preformed and is connected to the catheter tail end provided with an end hole. The end of the catheter head end is provided with the soft head. By the aid of the intervening and closuring partitioning catheter, establishment of a rail can be completed rapidly before being closured, time for the rail to be established and exposed in X rays can be shortened, and success rate of establishing the rail and entire surgery success rate of closuring the ventricular septal defect can be increased.

Description

technical field [0001] The invention relates to the field of ventricular septal defect closure of congenital heart disease, in particular to a transseptal catheter in the operation of interventional closure of ventricular septal defect of congenital heart disease. Background technique [0002] The current interventional occlusion methods can treat most congenital heart disease ventricular septal defects, and most of the occluders use nickel-titanium alloy occluders. However, the success rate of interventional closure of ventricular septal defect in each heart center at home and abroad is not the same. First of all, the methods and means of establishing the track of the left heart system-ventricular septum-right heart system before occlusion are not the same, resulting in different operation time and X-ray exposure time. The main reason is the lack of dedicated transseptal catheters. Most of the previous transseptal catheters used JR4.0 angiographic catheters or 3DRC cathete...

However, the success rate of interventional closure of ventricular septal defect in each heart center at home and abroad is not the same

First of all, the methods and means of establishing the track of left heart system-ventricular septum-right heart system before closure are not the same, resulting in different operation time and X-ray exposure time. The main reason is the lack of a dedicated transseptal catheter

Most of the previous transseptal catheters used JR4.0 angiography catheter or 3DRC catheter in coronary surgery, or the pigtail catheter with part of the head removed, and then reshaped. Experienced operators can quickly complete the shaping and send it into the main The orbit is established on the aortic valve, and inexperienced surgeons spend a lot of time on catheter shaping and orbit establishment, and the doctor and patient are always under X-ray exposure when the orbit is established, resulting in possible failure of the operation or prolonged operation time, And increased the potential adverse consequences of a large number of X-ray exposure

[0003] So far, there is no special transseptal catheter suitable for children and adults in the operation of ventricular septal defect. It is necessary to further standardize the method of establishing the orbit of the left heart system-ventricular septum-right heart system to increase the success rate of establishing the orbit and shorten the operation time. Operating time and X-ray exposure time
