Abstract

The invention belongs to the technical field of cardiac surgical instruments, and provides a guide stent and an injection system. The guide stent comprises an outer pipe; an inner pipe, wherein the outer pipe is telescopically arranged on the outer side of the inner pipe; an elastic bracket, wherein one end of the elastic bracket is connected with the outer pipe, and the other end is fixedly connected with the inner pipe; an elastic guide sleeve which is arranged on the elastic bracket; one or several guide pipes, wherein one end of each guide pipe is communicated with the bottom of the elastic guide sleeve, and the other end is connected with the side wall of the elastic support and communicated with the outer side of the elastic support. Through the above technical scheme, the problem that an injection needle is difficult to accurately position in a three-dimensional heart cavity when a catheter is injected through an endocardium is solved, and a series of problems that chest openingtrauma is large as well as anesthesia risks are high caused by chest opening transendocardial intracardiac injection, pericardial structures are directly damaged, postoperative scar adhesion furtherreduces the intervention effect, clinical application is difficult and the like are also avoided.

Description

technical field [0001] The invention belongs to the technical field of heart surgery instruments, and relates to a guide bracket and an injection system. Background technique [0002] With the development of the economy, especially the change of lifestyle, cardiovascular disease has become the number one killer threatening human life, and a variety of cardiovascular diseases can lead to heart failure, such as myocardial infarction, heart valve disease, cardiomyopathy, high blood pressure etc. For patients with heart failure, even if the primary cause is corrected, since the vast majority of cardiomyocytes are in a terminally differentiated state, the cells lack the ability to regenerate themselves, and once necrotic, it is difficult to regenerate, so the deterioration of cardiac function is difficult to reverse. In addition, the treatment of heart failure also includes cardiac resynchronization, left ventricular assist device, heart transplantation, etc., but all have their...
