Abstract

The invention provides a decompression assist device for cardiac aortic stenosis or incompetence. The decompression assist device is characterized by comprising a first clamp piece and a second clamp piece connected through a connecting shaft; the first clamp piece and the second clamp piece comprise a clamp arm and a clamp holder respectively; each of the clamp arms is provided with a bent arm; the front end of each of the bent arms is provided with an artery arm; a spring is arranged on the middle section of each of the bent arms; two ends of each of the springs are connected with the middle section of each of the bent arms of the first clamp piece and the second clamp piece; and each of the clamp holders is connected with an atrium support and positioning holes are formed on the edge of each of the atrium support.

Description

technical field [0001] The present invention relates to a medical device, and more particularly, the present invention relates to a decompression assist device for cardiac valve stenosis or regurgitation. Main classification number of the technical field of this application: A61B17 / 02 Sub-classification number: A61F2 / 24 Background technique [0002] There are valves in the heart and large blood vessels of the human body. The function of the valves is to ensure the one-way flow of blood flow, that is, arterial blood flows in the centrifugal direction and venous blood flows in the direction of the heart. Once the valve is damaged, it will disturb the blood flow and lead to disease. [0003] Heart valve disease is a disease mainly caused by congenital or acquired causes of pathological changes in the heart valves, mainly caused by heart blood flow disorders. When the heart valve is diseased, it will generally lead to the following two situations: one is the insufficiency of t...
