Surgical mitral stenosis balloon dilatation instrument set

Abstract

The invention relates to a surgical mitral stenosis balloon dilatation instrument set which is compose of a puncture sheath, a puncture needle, a pre-bent catheter, a guide wire, a pre-bent balloon catheter, a balloon catheter guide wire and a syringe. That puncture sheath is provided with a hollow cavity through which the puncture needle passes through. A guide hole is arranged on the pre-bent conduit along its axial direction, and a guide wire can penetrate through the guide hole; a guide hole is arranged along the axial direction of the pre-bent balloon catheter, a balloon is arranged at the front end of the pre-bent balloon catheter, a guide steel wire of the balloon catheter penetrates the guide hole, and the front section of the guide steel wire of the balloon catheter is soft; the pre-bent balloon catheter has one or more inner holes along the axial direction, the tail end of the inner hole is connected with the syringe, and the front end of the inner hole is connected with theballoon through the side hole. A surgical mitral valve stenosis balloon dilation instrument sleeve set has reasonable structure design, simple and convenient operation and easy mastery, low technicallevel requirement for a doctor, minimally invasive and safe, and has good popularization 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 ...

AI Technical Summary

Problems solved by technology

However, due to the medical interventional balloon dilatation under X-ray, because of the long surgical path, complicated instruments, and high difficulty in operation, the success rate is low and serious complications often occur, so it is basically eliminated now.
