Problems solved by technology

[0003] During the operation, it is necessary to use the X-ray machine for many times for a long time to contrast the heart, which will cause certain radiation damage to the medical staff and patients.
[0004] Moreover, due to the long length of the existing delivery device, complications such as blood vessel damage may be caused during the operation.

Abstract

The invention discloses a surgical conveying device for interventional treatment of congenital heart diseases, which comprises an outer sheathing canal, an inner sheathing canal, a push rod, a hemostatic valve, a loading sheath, a heart-opening combination device and a conveying combination device, wherein the heart-opening combination device is combined by the outer sheathing canal and the inner sheathing canal, and the conveying combination device is combined by the outer sheathing canal, the push rod, the hemostatic valve and the loading sheath. By using the surgical conveying device disclosed by the invention, no X-ray radiography is required in a surgical process, therefore, no radiation damage is caused on doctors and patients.

Description

technical field [0001] The invention relates to a medical device, in particular to a surgical delivery device for interventional treatment of congenital heart disease. Background technique [0002] The traditional interventional treatment of congenital heart disease adopts medical interventional treatment, which is to cut a small wound from the femoral artery and deliver the delivery device to the lesion along the femoral artery. Due to the relationship between the location of the lesion, the delivery device needs to have different angles to send the occluder into the location of the lesion. [0003] During the operation, it is necessary to use the X-ray machine for many times for a long time to contrast the heart, which will cause certain radiation damage to the medical staff and patients. [0004] Moreover, due to the relatively long length of the existing delivery device, complications such as blood vessel damage may be caused during the operation. Contents of the inve...
