Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a press button type artificial valve conveying device which comprises a mandrel, an outer sheath pipe, a screw, a first handle and a second handle, the screw is installed between the first handle and the second handle, the outer sheath pipe is fixedly connected with the first handle, and the mandrel is arranged in the outer sheath pipe, the first handle and the second handle in a penetrating mode. A valve is loaded between the mandrel and the outer sheath pipe, a knob, a connecting pipe and a press button assembly are installed on the second handle, and the screw drives the first handle and the outer sheath pipe to move towards the near end by rotating the knob so as to achieve positioning of the valve. By pressing the press button assembly and pulling the press button assembly to the near end, the connecting pipe drives the screw to move and is in linkage with the first handle and the outer sheath pipe to move to the near end so as to release the valve. The device is convenient to operate and stable in operation, and can realize accurate positioning and quick release of the artificial valve.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a push-button artificial valve delivery device and a delivery method. Background technique [0002] Heart valve refers to the valve between atrium and ventricle or between ventricle and artery. Valves play a key role in the heart's never-ending activity of circulating blood. Every human heart has four valves. The aortic valve connects the left ventricle to the aorta, the pulmonary valve connects the right ventricle to the pulmonary artery, the mitral valve connects the left atrium to the left ventricle, and the tricuspid valve connects the right atrium to the right ventricle. They all act as one-way valves, so that blood can only flow from one direction to the other and not back. [0003] Valvular heart disease is a common heart disease, the main clinical manifestations of mitral valve, tricuspid valve, aortic valve and pulmonary valve due to rheumatic feve...
