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 present invention relates to the technical field of medical instruments, and more specifically, relates to a delivery device. Background technique [0002] The valves of the heart are made of thin but extremely tough sheets of tissue that open and close as the heart contracts and relaxes. A normal human heart beats about 100,000 times a day, and its valves open and close about 100,000 times a day. Therefore, the valves of the heart must remain flexible and tense throughout a person's life, and can withstand the pressure of the heart chamber and the washing of blood for a long time. [0003] Valvular heart disease is one of the most common heart diseases in my country, mainly due to valve damage caused by rheumatic fever; in recent years, with the development of population aging, valve degeneration (including calcification and mucus degeneration, etc.) Damage is also increasing in our country; in addition, congenital valvular disease is also one of...
