Conveying device for interventional therapy of congenital heart disease in surgical department

Abstract

The invention relates to the field of interventional therapy instruments for heart diseases and discloses a conveying device for interventional therapy of the congenital heart disease in the surgicaldepartment. The device comprises a conveying sheathing canal, a connector, a hemostasis device, a transfer device, a pushing steel cable, a connection body, a plugging device and a cannula; the cannula of one side of the plugging device is in threaded connection with the connection body of one end of the pushing steel cable. According to the conveying device for interventional therapy of the congenital heart disease in the surgical department, by pulling an adjustment steel cable, under limit of a limit tube structure to a sliding body, the sliding body and the limit tube structure are bent relative to a fixing tube structure, so that the plugging device is bent relative to the fixing tube structure, when the long axis of the aorta is vertical to the ventricular septal defect direction ofthe heart valve, the plugging device is controlled to be vertical relative to the fixing tube structure, and it is guaranteed that when placed, the plugging device cannot be pulled by the pushing steel cable; it is guaranteed that the plugging device completely fits the plugging defect part, and the plugging effect is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of heart disease interventional treatment equipment, in particular to a delivery device for surgical interventional treatment of congenital heart disease. Background technique [0002] Cardiac surgery interventional therapy is a new technique for the diagnosis and treatment of cardiovascular diseases. It has the advantages of less trauma, no need for general anesthesia, no blood transfusion and short operation time. , sent into the heart catheter, through the specific heart catheter operation technology to diagnose and treat heart disease diagnosis and treatment methods, can be used to treat congenital heart disease such as left-to-right shunt congenital heart disease and congenital heart valve disease. [0003] In the treatment of congenital valvular heart disease (see Figure 3-4 ), the occluder 6 is sent to the congenital heart defect or the patent site for occlusion by delivering the sheath tube 1. However, when t...

Problems solved by technology

[0003] In the treatment of congenital valvular heart disease (see Figure 3-4 ), the occluder 6 is sent to the congenital heart defect or the patent site for occlusion by delivering the sheath tube 1. However, when the existing delivery device for interventional therapy delivers the occluder 6, since the long axis of the aorta is almost the same as The direction of the heart valve ventricular septal defect is vertical. When the occluder 6 is placed, the occluder 6 is pulled by the push cable 5, and its long axis direction cannot be parallel to the long axis of the heart valve ventricular defect, and the occluder 6 is placed obliquely. within the defect, but cannot be completely attached to the occluded defect, resulting in residual shunt, making the occluder 6 lose its effect, and the occluder 6 is threaded with the push cable 5, and after the occluder 6 rotates, it will cause Pushing the wire cable 5 and the occluder 6 threaded connection is too tight, which makes it more difficult to release the occluder and affects the progress of the operation
