Abstract

The invention relates to an embolization device. The embolization device comprises an embolization assembly and a conveyor, wherein the embolization assembly comprises a spring ring and a connecting piece arranged at one end of the spring ring; and the conveyor comprises an outer sleeve and an inner sleeve arranged in the outer sleeve in a penetrating mode, the inner sleeve comprises a main body section and a clamping section arranged at the far end of the main body section, the clamping section is detachably connected with the connecting piece, when the clamping section is located in the outer sleeve, the connecting piece is bound in the clamping section, and when the clamping section extends out of the outer sleeve, the connecting piece is separated from the clamping section. According to the embolization device, in the conveying process, the connecting piece can be clamped in the clamping section, connection between the embolization assembly and the conveyor is stable and reliable,in the releasing process, the connecting piece can be released only by pushing the inner sleeve out of the outer sleeve, and the operation is convenient and rapid.

Description

Technical field [0001] The invention relates to the field of medical instruments, in particular to an embolization device. technical background [0002] Intracranial aneurysms are mostly abnormal bulges on the wall of intracranial arteries, which is the first cause of subarachnoid hemorrhage, and subarachnoid hemorrhage is one of the main types of hemorrhagic stroke in clinic. There are two main treatments for aneurysms: surgical clipping and interventional therapy. Clinical trials show that the mortality rate of interventional therapy is lower than that of surgical therapy. [0003] Coil embolization of intracranial aneurysms is an interventional therapy technique developed in recent ten years. It is easy to operate, minimally invasive, and quick to recover, and can achieve the effect similar to that of surgical clipping. For some cases that cannot be operated or failed, coil embolization may be the only method. [0004] The surgical operation method of coil interventional thera...
