Description
Technical field:
The utility model relates to heart assistance cycle arts, and in particular, to a kind of minimally invasive catheter type synchronization heart assistance
Device.
Background technique:
Heart failure is to seriously threaten the disease of human life, and there are about 1/5 cardiacs every year in the whole world eventually
Development is heart failure, at present China's heart failure disease incidence reach 0.9% and 5 years death rates be more than 60%.When traditional drug
Treatment has certain limitation, cannot reach satisfactory effect, and heart transplant faces donor shortage again, the difficulty such as postoperative rejection
When, researchers propose that the method for helping heart to restore using mechanical device has developed ventricular assist device.From upper
A sixties in century, by many years studies and clinical application, the application of ventricular assist device was from painstaking effort since clinical application
Pipe hand Anabiosis after operation, bridge to heart transplantation or substitution are expanded to the permanent treatment of recovery or even the heart failure of myocardial function.
The bridge that ventricular assist device acts not only as transition before heart transplant is also to lead to the canoe of cardiac muscle recovery to improve heart failure and suffer from
Person's quality of life is used for the treatment of patients with heart failure.
Ventricular assist device is the most effective treatment method of the generally acknowledged all kinds of terminal phase heart failures in the whole world.From the upper world 60 years
The third generation suspension blood pump that today is developed to for first generation pneumatic blood pump, second generation axial flow blood pump, it is difficult to experienced several generations scientist
Pungent research progress.China starts to carry out the research of ventricular assist device at the beginning of the eighties in last century, though the effort through several generations, with
Foreign countries there is no the domestic heart-assist device of commercialization for clinical application so far compared to still there is larger gap.Though there are commodity in foreign countries
The ventricular assist device of change, but set of device price is up to 500,000 yuan -100 ten thousand yuans, but set of device is at high price.Cause
This develops function admirable, cheap new type domestic ventricular assist device becomes the task of top priority.By Chinese engineering team and
Medicine team unity successfully develop first, China it is implantable, third generation ventricular assist device, zoopery created state
It is implanted into the longest survival record of third generation ventricular assist device, China's third generation ventricular assist device development obtains great prominent
It is broken.
But domestic third generation ventricular assist device be implanted and non-pulsation, both needed surgical operation implantation cause compared with
