Abstract

The embodiment of the invention discloses a conveying device. The device comprises an outer conveying tube, a push rod structural component, an inner tube structural component and a functional handle, wherein at least two fixed claw hooks are arranged on the top of a fixed claw in the push rod structural component. In the embodiment of the invention, at least two fixed claw hooks are arranged on the top of the fixed claw, and the fixed claw hooks are hooked on a recycling hole of a valved stent when the device is used, and the device is released layer by layer, so that the heart valve can be recycled at any time through a handle if the heart valve is not placed on a proper position by a unique connecting mode of the conveying device and the heart valve.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a delivery device. Background technique [0002] The heart valve is composed of thin and extremely tough sheet-like tissue, and the valve opens and closes as the heart contracts and relaxes. The heart of a normal person beats about 100,000 times a day, and the valve opens and closes 100,000 times. Therefore, the valve of the heart must remain flexible, tense, and able to withstand the pressure of the heart cavity and the washing of blood for a long time. [0003] Heart valvular disease is one of the most common heart diseases in my country, among which valve damage is mainly caused by rheumatic fever; in recent years, with the development of the aging population, valve degeneration (including calcification and mucous degeneration) and metabolic disorders valves Damage is also increasing in our country; in addition, congenital valvular disease is also one of the common ...
