Net disk turbulence device and turbulence device conveying system

Abstract

The invention relates to a net disk turbulence device which comprises a turbulence net disk, the turbulence net disk comprises a disk body part and a combination part, the outer side of the combination part is provided with a development mark, the inner side of the combination part is connected with an embolism object through a polymer wire, the outer side of the development mark is connected witha release part, and the disk body part of the turbulence net disk is attached to the inner wall of a tumor cavity. The invention further relates to a turbulence device conveying system which comprises the net disc turbulence device and a conveying steel pipe, the near end of the conveying steel pipe is sleeved with an insulating pipe, and the insulating pipe is sleeved with a conductive pipe. A supporting spring is arranged at the far end of the conveying steel pipe, a second negative electrode is arranged at the far end of the supporting spring, the second negative electrode is connected with the conveying steel pipe through a negative electrode conductive wire arranged in the conveying steel pipe in a penetrating mode, and a second positive electrode is arranged at the far end of the second negative electrode and connected with the conductive pipe through a positive electrode conductive wire arranged in the conveying steel pipe in a penetrating mode; the far end of the second positive electrode is connected with the release part; the second positive electrode and the second negative electrode can be communicated through electrolyte in blood to form a loop, the release part is broken through electrochemical dissolution, and the net disc turbulence device is left in the tumor cavity.

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 circui...
