Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly, to artery clamp device and apparatus for fastening.
Background technology
Acute cerebrovascular diseases, also known as apoplexy, cerebral apoplexy or cerebrovascular accident are cerebral vessels or it is dynamic to supply the neck of brain
The focal blood circulation disorder of brain caused by the lesion of arteries and veins, and caused with local nerve afunction by brain blood dyshaemia
The disease being characterized.Apoplexy can be divided into ischemic and hemorrhagic two major classes according to the cause of disease, pathology, the former includes transient cerebral ischemia
Breaking-out, limitation cerebral infarction；The latter includes cerebral hemorrhage and subarachnoid hemorrhage.Limitation cerebral infarction abbreviation cerebral infarction refers to
Because of Arterial thrombosis, embolus, inflammation, damage etc. cause local brain tissue acute ischemia, necrosis.Wherein cerebral thrombosis is scarce
Common type in courageous and upright cerebrovascular disease, in national standard《Tcm clinical practice diagnosis and treatment term》In, it will be including cerebral thrombosis
Ischemic cerebrovascular disease be specifically termed as " Ischemic Apoplexy ".
It is to study cerebral ischemia pathophysiological change and evaluation to have to establish the ideal live body cerebral ischemia animal model of norm controlling
Imitate the means of intervening measure.To understand the observation of the pathogenesis and evolution process and realization of headstroke to curative effect of medication, right
There is an urgent need for a kind of success rate height, the experimental animal moulds that stability is good, operation is efficient, disturbing factor is smaller in the experimental study of headstroke
Type.By good stability and repeatability, cerebral ischemia re-pouring animal model becomes the weight of research ischemic cerebrovascular disease
Approach is wanted, researcher is helped utmostly to simulate the pathological process of mankind's Ischemic Stroke.
The production method that scholars have invented a variety of arteria cerebri media focal cerebral ischemia in rats in recent years, such as craniotome tool
It is block system, microembolus embolism blocked method, chemical stimulation inducing thrombosis block system, photochemical induction thrombosis method, intravascular
Bolt line Blocking Method etc..Wherein early in 1986, the big of achievable Reperfu- sion is made in the line brush invented by Japanese scholars Koizumi
Brain Middle cerebral artery occlusion rat model, because cranium, wound are small, Reperfu- sion can be achieved without opening for it, closer to acute human cerebral infarction warp
The pathological process of revascularization after drug thrombolysis, and cause the extensive concern of scholars.
At present by recognized by numerous scholars be the foundation such as Longa arteria cerebri media ischemic (MCAO) Reperfu- sion animal mould
Type.But in specific experiment operating process, this method still exposes some defects, and plug wire operation is because of blood vessel feature out of shape in operation
It is easily affected by human factors, leads to experimental animal disability rate, the death rate are high, model success rate is low etc..Such as：Arteria carotis communis clip
When, since the operation of dynamics and angle artificially manipulates entirely, notch will cause arteria carotis communis to be broken completely very much greatly, the too small meeting of notch
Cause the insertion of fishing line very difficult.The careless slightly failure that modeling will be caused to test, by being found when reading pertinent literature,
The current operating instruction for still lacking detailed to the modelling process specification, standard, it is difficult according to such document to cause learner
Complete the preparation work of model.
