Description
Technical field
The present invention relates to medical apparatus technical fields, more particularly, to a kind of aorta arch constriction art regulating device and its behaviour
Make method.
Background technology
Aorta arch constriction is a kind of important method applied in heart disease research.This method is for simulating hypertension
Cardiopathic damage establishes the increased pathological conditions of cardiac afterload in vivo in experimental animal (mouse), to cardiac hypertrophy,
The processes such as heart failure are simulated and are studied.This method application mechanical means (ligation applies blood vessel titanium folder) causes the arch of aorta
Constriction is narrow, to cause narrow width proximal pressure rise, at this time heart afterload increase, further occur myocardial hypertrophy with
And heart failure.
In the art, the mechanical stenosis manually applied will generate important shadow for the pathophysiological process of disease
It rings, it is known that stenosis is heavier, the increase of cardiac afterload is more apparent.And in various degree narrow, it can be to experimental result
It is had an important influence on the pathophysiological process of animal pattern.Therefore for the adjusting of constriction degree and control for the arch of aorta
Constriction technology is most important.
Existing technology can carry out constriction by two different methods to the arch of aorta, and a kind of method is using operation seam
Zygonema ligatures, and another method is to carry out part folder to the arch of aorta using Clip Applier release titanium folder to close.Two methods are for master
It is standard that the control of arch of aorta constriction degree, which is by application syringe needle, i.e.,：Using different-diameter syringe needle as reference
Standard carries out constriction to blood vessel, and the diameter (when suture ligature) or anteroposterior diameter constriction to make blood vessel reach (when titanium folder portion point folder closes)
To needle diameter (usually identical as needle diameter), to cause the narrow completion model of blood vessel.
But since the syringe needle of application different model is used as the standard of referring to so that the degree of aorta arch constriction cannot connect
Continuous variation, i.e.,：Aorta arch constriction diameter or size can only be syringe needle size specification (be usually 27G syringe needle -0.4mm and
Two kinds of 26G syringe needles -0.45mm), it cannot achieve fine-tuning for diameter or constriction degree.
