Abstract

The invention discloses a conveying system for implanting an artificial prosthesis into the body of a patient, the artificial prosthesis comprises a support and a positioning frame, and the conveying system comprises a frame body; the catheter mechanism comprises a stent catheter assembly and a positioning catheter assembly which are sleeved with each other, the stent is installed at the far end of the stent catheter assembly, and the positioning frame is installed at the far end of the positioning catheter assembly; the control mechanism is installed on the frame body and comprises a support control assembly and a positioning control assembly, the near end of the support catheter assembly is connected to the support control assembly, and the near end of the positioning catheter assembly is connected to the positioning control assembly; the positioning control assembly is used for driving the positioning catheter assembly to act so as to implant the positioning frame to the preset position of the human body, and the support control assembly is used for driving the support catheter assembly to act so as to adjust the position between the support and the positioning frame and assemble the support and the positioning frame in the human body. A support and a positioning frame of the artificial prosthesis can be loaded and sequentially delivered at the same time and assembled in vivo, the structure is simple, and operation is convenient.

Description

technical field [0001] The present invention relates to the medical field, and further relates to a delivery system for implanting an artificial prosthesis into a patient, in particular, the artificial prosthesis is an artificial heart valve. Background technique [0002] The heart is divided into two parts, left and right, each part includes a ventricle and an atrium, between the ventricle and the ventricle and between the atrium and the atrium are separated by the interventricular septum and the atrial septum, and there is a function between the atrium, the ventricle and the artery to prevent blood backflow valve. Among them, the valve between the left atrium and left ventricle is the mitral valve, 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 aorta is the aortic valve. The valve between the pulmonary arteries is the pu...
