Abstract

The invention relates to the technical field of medical instruments, in particular to an implantable atrium shunting device. The implantable atrium shunting device comprises a left disk, a right diskand a waist disk, wherein disk centers of the left disk, the right disk and the waist disk are shunting holes; a left disk connecting wire is arranged at the maximum diameter of the left disk in a circumferential direction; a wire end of the left disk connecting wire is located on the outer surface of a take-up harness and fixed in a take-up ball; and when the take-up ball rotates relative to thetake-up harness, the left disk connecting wire is wound on the surface of the take-up harness, so that the maximum diameter of the left disk is reduced. Due to the mode and the novel structural design, in the embodiment of the invention, the entire implantable atrium shunting device can be recycled at any time; the technical problem that an existing implantable atrium shunting device cannot be recycled is solved; the life of a patient is prolonged; and the device is recycled more conveniently and quickly.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implantable atrial shunt device. Background technique [0002] Heart failure (heart failure) referred to as heart failure refers to the failure of the venous blood to fully discharge the heart due to the dysfunction of the systolic function and / or diastolic function of the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system, resulting in Cardiac circulatory disorder syndrome, which is characterized by pulmonary congestion and vena cava congestion. Heart failure is not an independent disease, but the end stage of the development of heart disease. The vast majority of heart failures begin with left heart failure, that is, the first manifestation is pulmonary circulation congestion. [0003] Sustained high pressure in the left atrium pressurizes the left ventricular cavity, increases the filling volume, and incre...
