Implantable atrium shunting device

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.
