Adjustable type microtubular for cerebrovascular intervention
The present invention relates to the field of medical instrument technology, more particularly, to the adjustable type microtubular of cerebrovascular intervention.
Cerebral hemorrhage refers to mainly there there is with cerebrovascular lesion occurrence cause in non-traumatic cerebral essence caused by cerebral hemorrhage
It closes, i.e., it is related with the aging etc. of hyperlipidemia, diabetes, hypertension, blood vessel.Traditional treatment is but the drug with drug after cerebral hemorrhage
Stop blooding slower, after there is blood coagulation, operation of opening cranium often leaves sequelae.And (artery micro-wire expands hand to interventional therapy operation
Art and stenter to implant operation) it is a series of diagnosis carried out by using intervention apparatus and material and modernization digital diagnosis and treat equipment
It is operated with treatment；It only needs local anaesthesia compared with traditional surgery, opens the osculum of 1-2mm, thus it has
The advantages that blood is few, wound is small, few intercurrent disease, fast and safe and reliable post-operative recovery, so as to mitigate what patient was born significantly
According to above-mentioned, by opening a duck eye at human thigh's arteries position, then cranial nerve interventional therapy refers to
With a micro-wire, deeply the cerebrovascular, the minimally invasive intracavity operation for carrying out cranial vascular disease are treated in patient body.Wherein microtubular exists
After going deep into designated position, in order to improve the stabilization for the treatment of and accurate, the fastness and stability of microtubular are most important but existing
Microtubular lack good fixation because structure is simple, has a single function, therefore not only increase the risk of operation, also increase
The operating burden of medical staff, in view of disadvantages described above, it is really necessary to the adjustable type microtubulars designed for cerebrovascular intervention.
