Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an integrated release umbrella-shaped protective bracket for an internal carotid artery.
Background
Carotid Angioplasty and Stenting (CAS) are minimally invasive therapies for treating carotid stenosis. Since the introduction of this approach 20 years ago, the use of CAS has steadily increased, with CAS being used in 8% of 107000 carotid surgeries performed in europe in 2001. Without the discomfort of a sizeable neck incision, the prospect of outpatient surgery has led patients to decide to discard carotid endarterectomy, the first procedure used to treat carotid bifurcation disease in the past fifty years.
According to the above, the release mechanism of the prior clinical traditional internal carotid artery elastic stent and the recovery mechanism of the protective umbrella are two independent systems, when the support is released, the support release system needs to be withdrawn firstly, then the protective umbrella is recovered by the protective umbrella recovery conduit, therefore, the secondary operation is needed, the operation is complicated, the problem that the thrombus in the protective umbrella escapes easily, meanwhile, the released bracket is needed to pass through in the process of recovering the catheter by the protective umbrella again after the bracket release system is withdrawn, if the blood vessel is circuitous or the stent is not well pre-expanded, the recovery catheter of the protective umbrella often meets great resistance and can not pass through the stent to reach the position of the protective umbrella, therefore, the protective umbrella cannot be recovered, serious complications such as vascular occlusion and the like are caused, and finally great hidden danger is brought to clinical popularization and application.
