Abstract

The invention discloses an electrocoagulation guide wire system used for arterial aneurysm embolism. The electrocoagulation guide wire system comprises a power supply, a positive electrode hypotube and a positive electrode platinum-iridium ring, wherein a PTFE inner insulating layer is arranged between the positive electrode hypotube and the positive electrode platinum-iridium ring, a positive electrode conductive wire is arranged in the PTFE inner insulating layer, two ends of positive electrode conductive wire are electrically connected with the positive electrode hypotube and the positive electrode platinum-iridium ring, a negative electrode hypotube and a negative electrode HHS tube are fixedly connected to the outer side of the PTFE inner insulating layer, the positive electrode conductive wire is connected with the positive electrode of the power supply, both the negative electrode hypotube and the negative electrode HHS tube are connected with the negative electrode of the powersupply, the negative electrode HHS tube and the negative electrode hypotube are fixedly connected through welding, same first epoxy glue is arranged between the positive electrode hypotube and the negative electrode hypotube, the outer sides of the positive electrode hypotube and the negative electrode hypotube are fixedly connected with one same first PET heat shrinkable tube, and the outer sideof the first PET heat shrinkable tube is fixedly connected with a PTFE heat shrinkable tube. The electrocoagulation guide wire system is easy to operate, and convenient in use and treatment, and theuse requirements can be satisfied.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to an electrocoagulation guide wire system for aneurysm embolization. Background technique: [0002] Cerebral aneurysm is a sac-shaped tumor formed by the outward expansion of the local vessel wall due to the structural dysplasia of the cerebral artery wall or the damage or aging of the arterial wall caused by trauma or arteriosclerosis. It is the first cause of subarachnoid hemorrhage , in cerebrovascular accidents, second only to cerebral thrombosis and hypertensive cerebral hemorrhage, cerebral aneurysm is the invisible killer of life, if it ruptures, the disability rate and fatality rate. [0003] At present, the treatment methods for cerebral aneurysms mainly include conservative medical treatment, craniotomy and endovascular interventional treatment. The treatment methods are inconvenient and cannot meet the needs of use. Invention content: [0004] The purpose of ...
