Abstract

The invention discloses a valve decoupling mechanism and a valve delivery device. The valve decoupling mechanism comprises a mounting housing and a fixing barrel slidingly arranged in the mounting housing, wherein a mounting groove is formed in the mounting housing; a limiting groove is formed in an outer wall of the fixing barrel; the fixing barrel is sleeved with a limiting piece; the limiting piece is clamped in the limiting groove; the limiting piece is arranged in the mounting groove movably; a limiting hole is formed in the limiting piece; the valve decoupling mechanism further comprisesa limiting mechanism penetrating through the limiting hole to limit the limiting piece, and an elastic piece arranged in the mounting housing; the elastic piece allows the limiting mechanism to be inserted into the limiting hole in a first; and an outer pipe moving mechanism can act on the limiting mechanism to allow the limiting mechanism to resist an elastic force of the elastic piece to exit the limiting hole in a second state.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a valve decoupling mechanism and a valve delivery device. Background technique [0002] The heart is a very important organ of the human body, which provides power for the blood circulation of the human body. The heart is divided into two parts, the left and the right. Each part contains a ventricle and an atrium. There are valves between the atria, ventricles, and arteries that prevent blood from flowing back. The valve between the left atrium and left ventricle is the mitral valve, the valve between the right atrium and right ventricle is the tricuspid valve, the valve between the left ventricle and the aorta is the aortic valve, and the valve between the right ventricle and the aorta is the aortic valve. The valve between the pulmonary arteries is the pulmonary valve. [0003] The above-mentioned valves will open and close correspondingly with the contraction and rel...
