Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a network disk turbulence device and a flow turbulence device delivery system. Background technique [0002] Aneurysm is a very common vascular disease, which is caused by the lesion or injury of the arterial wall, resulting in localized or diffuse expansion or bulging of the arterial wall. any part of the system. Once an aneurysm ruptures, serious consequences may result. Such as intracranial aneurysm rupture, resulting in subarachnoid hemorrhage, severe cases can cause vasospasm and large-scale cerebral infarction, leading to hemiplegia and coma. The current treatment options for aneurysms mainly include open surgery and endovascular intervention. The open surgical treatment plan needs to open the body cavity surrounding the aneurysm, such as craniotomy and thoracotomy, which will cause huge damage to the patient's body, and the postoperative recovery period is long....

Problems solved by technology

[0003] At present, the embolisms used in the endovascular interventional treatment of aneurysms are mainly coils. In the operation, in order to achieve the effect of thrombosis in the tumor, sometimes it is necessary to use multiple coils, and the coils are expensive. High cost

Moreover, if the coil is used alone, a stent needs to be placed in the blood vessel, and the patient needs to take medicine for a long time

[0004] In addition, the current delivery system for transporting emboli generally uses electrolysis to separate the emboli from the delivery device. The traditional electrolysis uses the human body as the circuit, the anode is connected to the power supply through a stainless steel delivery rod, and the cathode is inserted into the human arm and other parts. The connection between them is realized through the longer human blood vessels, and the relief is very slow, and the duration is about 30 to 60 seconds.

In the latest electrolysis device, the anode is connected to the conductive tube with a conductive wire, but the delivery rod and the supporting spring are used as the cathode to realize the conductive circuit, and the release time is improved, about 10 to 15 seconds, and there is also the problem of long operation time. question
