Abstract

The invention provides an aneurysm embolization catheter and an aneurysm operation auxiliary device, which relate to the technical field of medical devices. The aneurysm embolization catheter comprises a connector and a catheter body, wherein the connector is connected with one end of the catheter body. The catheter body includes a multi-lumen structure and an inflatable balloon disposed on the external surface of the catheter body. The multi-cavity structure comprises a guide wire guide cavity, a spring coil guide cavity and an inflation cavity. The inflatable cavity is communicated with theinflatable balloon. The connector is provided with a guide wire inlet, a spring coil inlet and an inflation interface, which are one-to-one correspondingly communicated with the guide wire guide cavity, the spring coil guide cavity and the inflation cavity. The other end face of the catheter body is provided with a guide wire outlet communicating with the guide wire guide cavity. A spring coil outlet communicating with the spring coil guide cavity is arranged on the outer surface of the catheter body corresponding to the position of the inflatable balloon. The catheter and the device solve thetechnical problems of complicated operation and easy winding of the spring coil and the protective balloon catheter in the prior art.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an aneurysm embolization catheter and an aneurysm operation auxiliary device. Background technique [0002] Normal peripheral arterial vessels dilate into capsules, which are called aneurysms. Aneurysm walls are weaker and less elastic than normal vessel walls, and are prone to rupture and bleeding leading to hemorrhagic shock. If aneurysm rupture occurs in an intracranial artery, patients often present with severe headache, limb paralysis or even loss of consciousness. In addition, the blood flow in the tumor cavity is in a vortex state for a long time, which is prone to secondary thrombus. If the thrombus falls off to the peripheral artery, it can also lead to acute arterial embolism, manifested as acute ischemic necrosis and functional loss of distal organs. Therefore, peripheral aneurysms are extremely dangerous if left untreated. [0003] With the development of en...
