Abstract

The invention discloses a delivery system for implanting an artificial prosthesis into a patient. The artificial prosthesis includes a bracket and a positioning frame. The delivery system includes: a frame body; The catheter assembly, the stent is installed at the distal end of the stent catheter assembly, and the positioning frame is installed at the distal end of the positioning catheter assembly; the control mechanism, installed on the frame body, includes a stent control assembly and a positioning control assembly, and the proximal end of the stent catheter assembly is connected to the stent a control assembly, the proximal end of the positioning catheter assembly is connected to the positioning control assembly; the positioning control assembly is used to drive the positioning catheter assembly to move, so as to implant the positioning frame into a preset position of the human body, and the stent control assembly is used to drive the stent catheter assembly to move, To adjust the position between the bracket and the positioning frame, and assemble the bracket and the positioning frame in the human body. The stent and the positioning frame of the artificial prosthesis can be loaded at the same time and delivered in sequence, and assembled in the body, and the structure is simple and the operation is convenient.

Description

technical field [0001] The present invention relates to the medical field, and further to a delivery system for implanting an artificial prosthesis in a patient, in particular, the artificial prosthesis being 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, and between the ventricle and the ventricle and between the atrium and the atrium is separated by the interventricular septum and the atrial septum. valve. Among them, the valve between the left atrium and the left ventricle is the mitral valve, the valve between the right atrium and the 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 right ventricle is the aortic valve. The valve between the pulmonary arteries is the pulmonary valve. [0003] The aforementioned valve will open and close correspondingly...
