Embodiment Construction

[0019] The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.

[0020] Such as Figure 1~3 As shown, an interventional artificial heart valve delivery device with a biased release structure includes a delivery device 1 and a nursing device 2. The delivery device 1 is composed of a delivery tube 3, a cavity 4, an elastic support 5, and a release sleeve 6. , the delivery pipe 3 is a tubular structure made of a nanocomposite material prepared by a sol-gel method with zirconium dioxide as the dispersed phase and zirconate as the precursor, between the zirconium dioxide and the zirconate The molar ratio is 1:1.2, the delivery tube made has high mechanical strength, high tear strength and tensile strength, and good thermal and chemical stability. One end of the delivery tube 3 is connected to the handle 7, and the other end is conne...

Abstract

The invention discloses an intervention type heart valve prosthesis conveying device with a bias release structure. The intervention type heart valve prosthesis conveying device comprises a conveying device and a nursing device. The conveying device is composed of a conveying pipe, a cavity, an elastic support and a release sleeve. A valve storage is arranged in the cavity, the elastic support is located at the joint of the conveying pipe and the cavity, the release sleeve is located at the joint of the conveying pipe and the elastic support, the nursing device is nested in the conveying device to perform axial movement, the nursing device is composed of a pair of hemostatic forceps, a liquid flow guiding pipe, a bias assembly and a medicine ring, the pair of hemostatic forceps is connected with a locking screw, the liquid flow guiding pipe is connected with the pair of hemostatic forceps, and the medicine ring is connected with a heart valve support. The device is simple in structure, convenient to use, high in release success rate and applicable to various ways of conveying of intervention type heart valve prostheses.

Description

technical field [0001] The invention relates to a human tissue substitute and its implantation device, in particular to an interventional artificial heart valve delivery device with a biased release structure. Background technique [0002] The heart is the most important organ of the human body. The heart is divided into two parts, the left and the right, and each part includes the atrium and the ventricle. The left and right atria and right and left ventricles are separated by the atrial and ventricular septum, respectively. There are four heart valves in the heart, namely the tricuspid valve, pulmonary valve, mitral valve and aortic valve. In the human blood circulation system, the four heart valves play a vital role. The hypoxic blood in the systemic circulatory system enters the right atrium through the vena cava, and then enters the right ventricle through the tricuspid valve. The contraction of the right ventricle pushes the blood into the pulmonary circulatory syste...
