Artery peripheral sucker stent and mounting method thereof

Abstract

The invention belongs to the technical field of artery interventional medical instruments, and discloses an artery peripheral sucker stent and a mounting method thereof. A net pipe stent is provided with supporting rods, each supporting rod is formed by connecting a plurality of V-shaped rods end to end, and every two opposite V-shaped rods form a rhombic mesh; an opening is formed in one side ofthe net pipe stent; a sucker stent is arranged in the middle of the net pipe stent; and a plurality of micro suckers are arranged inside the sucker stent. According to artery peripheral sucker stent disclosed by the invention, an intravascular operation mode is changed into a mode of performing operations from the vascular outer membrane, and radial uniform adsorption along the periphery of the pipe wall is carried out on the vascular outer membrane at a narrow part by adopting a sucker type stent auxiliary device, so that the otorhinolaryngeal cavity is uniformly enlarged, the cerebral bloodflow is increased, the ischemia and hypoxia symptoms of the brain are improved, the situation that a patient having an internal carotid artery stent needs to take anticoagulant drugs orally for a longterm to cause more serious complications can be avoided, the pain of the patient is relieved, blood vessels do not need to be blocked, and the safety coefficient is high.

Description

technical field [0001] The invention belongs to the technical field of arterial interventional medical devices, and in particular relates to an arterial peripheral suction cup bracket and an installation method thereof. Background technique [0002] At present, hypoxic-ischemic encephalopathy has become a major risk factor that threatens human health. One of the factors leading to the high incidence of this disease is directly related to the gradual aggravation of atherosclerosis. With age, the compliance of blood vessel walls Decline, internal carotid artery device and vertebrobasilar artery, the two main blood supply devices of the brain, may have arterial lumen stenosis caused by atherosclerosis, which will cause insufficient blood supply to the brain and lead to ischemic hypoxic encephalopathy . [0003] The clinical treatment of ischemic hypoxic encephalopathy mainly includes: internal carotid artery stent implantation for patients with internal carotid artery stenosis...

AI Technical Summary

Problems solved by technology

[0006] (2) The risk of surgical operation is high. Temporary occlusion of the internal carotid artery and then intravascular operation are likely to cause serious complications due to cerebral ischemia and surgical site hemorrhage.

[0007] The difficulty in solving the above problems and defects is: because the alloy material is commonly used in the internal carotid artery stent system, it is easy to affect blood components such as red blood cells and platelets from the perspective of its network structure itself. At present, in order to prevent this complication An effective method is to take anticoagulant drugs for a long time after placing the stent system, but the problem with long-term use of anticoagulant drugs is that the patient's own blood coagulation mechanism is destroyed, which often leads to a significantly increased risk of bleeding

In order to prevent the occurrence of bleeding, patients need to go to the hospital to draw blood regularly to test the four coagulation indicators, and often need to adjust the dosage of drugs, which has a great impact on the patient's body and mind. Greatly increased risk after stent implantation
