Abstract

The invention relates to the technical field of medical instruments, and discloses a prosthetic valve conveying system. The conveying system comprises a balloon connecting pipe, an adjustable bent outer pipe connected to the outside of the balloon connecting pipe in a sleeving mode, an operating handle arranged at the near end and a valve mounting part arranged at the far end. The operating handlecomprises: a fine adjustment scale part which sleeves the balloon connecting pipe, wherein a first dial is arranged on the fine adjustment scale part, and a locking part capable of locking the balloon connecting pipe is arranged at one end of the fine adjustment scale part; a locking knob which is in threaded connection with the exterior of the locking part, wherein the balloon connecting pipe can be locked or released by rotating the locking knob; and a fine adjustment knob which is in threaded connection with the exterior of the fine adjustment scale part, wherein the fine adjustment scalepart can be driven to move by rotating the fine adjustment knob so as to drive the balloon connecting pipe to move. The system is easy to operate and convenient to use, a doctor can visually know theconveying position of the valve at the position of the operating handle, rapid and accurate adjustment operation is carried out, and finally the valve can reach the ideal release position.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an artificial valve delivery system. Background technique [0002] The heart is an important organ of the human body, which provides circulation for human blood. There are four sets of valves inside the heart, which control the direction of blood flow and effectively prevent valve regurgitation. The valve between the left atrium and left ventricle is the mitral valve, and 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 pulmonary artery is the pulmonary valve. Problems with the valves will lead to insufficient blood supply to the heart, increase the burden on the heart, and lead to heart failure. For this type of heart disease, the traditional treatment method is thoracotomy and valve replacement surgery. This treatmen...
