Abstract

The invention belongs to the technical field of minimally invasive treatment of cardiac surgery, and particularly refers to a surgical mitral stenosis balloon dilatation instrument set. The surgical mitral stenosis balloon dilatation instrument set comprises a puncture sheath, a puncture needle, a preflex catheter, a preflex balloon catheter, a guiding wire, a balloon guiding wire and a syringe, wherein the puncture sheath is provided with a hollow cavity along the axis direction, and the puncture needle passes through the hollow cavity; the preflex catheter is provided with a guiding hole along the axis direction, and the guiding wire penetrates the guiding hole; the preflex balloon catheter is provided with a guiding cavity along the axis direction. The front end of the preflex balloon catheter is provided with a balloon, the balloon guiding wire penetrates the guiding cavity, and the front section of the balloon guiding wire is soft. The surgical mitral stenosis balloon dilatation instrument set is reasonable in structure design, simple and convenient to operate, easy to master, low in technical requirements for doctors, minimally invasive and safe, and has good promotion and application value.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgical treatment of heart disease, and specifically provides a mitral valve stenosis balloon expansion device set for surgery. Background technique [0002] With the rapid development of social economy, people's living standards have been greatly improved, but at the same time, the pressure of life and work is increasing, resulting in various diseases that affect people's health. Among them, mitral valve stenosis is a common rheumatic heart disease, which seriously affects the life of patients. At present, there are two conventional treatment methods for mitral valve stenosis: one is surgical operation. After establishing extracorporeal circulation, the patient's heart is cut open, and after the narrow mitral valve is resected, an artificial valve is implanted. The second is that under X-ray, the internal medicine department delivers the expansion balloon to the mitral valve orifice ...
