Problems solved by technology

[0005] However, after the patient is implanted with the heart defect occluder of the above structure, due to the existence of the connecting hole (ie the axial through hole in CN202776633U), the cardiopulmonary function cannot be effectively improved all the time, which is not conducive to its recovery

Abstract

The present invention relates to the field of cardiovascular medical treatment, and specifically discloses an adjustable heart defect occluder, comprising a first umbrella disc, a second umbrella disc and a waist between the first umbrella disc and the second umbrella disc, the first umbrella disc The plate is provided with a first through hole, the second umbrella plate is provided with a second through hole, and the waist is provided with a communication channel for communicating the first through hole and the second through hole; the first through hole, the second through hole or the communication A regulating device for adjusting the flow rate is provided at the hole. During treatment, the occluder can be positioned at the heart defect of the patient first, and the flow rate can be adjusted to the maximum value through the regulating device, so that the communication structure formed by the first through hole, the second through hole and the communication channel can play the role of transmitting pressure. Function; then according to the patient's recovery, the flow can be gradually reduced through the adjustment device to adapt to the patient's recovery, until the flow in the final connecting structure reaches the minimum value, thereby achieving complete closure of the defect.

Description

technical field [0001] The invention relates to the field of cardiovascular medicine, in particular to an adjustable heart defect occluder. Background technique [0002] Heart defects include atrial septal defect (ASD) and ventricular septal defect (VSD), which refers to the abnormality of the atrial septum / ventricular septum in the process of its occurrence and absorption, which fails to close normally, causing it to be between the left and right atrium / left and right ventricle. Residual through-holes generally require closure for treatment. The main instrument used in the occlusion operation is the occluder, which can be implanted by intervention; the traditional occluder is generally a double-disc thin waist structure (including the head umbrella disk, the tail umbrella disk and the head umbrella disk The waist between the umbrella plate and the tail umbrella plate), through the clamping effect of the left and right umbrella plates on the residual tissue of the atrial se...
