Pushing core wire of medical implant and medical device

Abstract

The invention provides a pushing core wire of a medical implant and a medical device. The pushing core wire is used for pushing the medical implant and comprises a sleeve assembly, a mandrel and a recycling assembly; the mandrel is used for being movably arranged in the sleeve assembly; the recycling assembly comprises a recycling part and a supporting part; the recovery assembly has a first state and a second state, and when the recovery assembly is in the first state, the recovery assembly is used for keeping a preset distance from the medical implant; and when the recovery assembly is in the second state, the recovery assembly is used for at least partially pressing against the medical implant or being inserted into a hole of the medical implant to recover the medical implant. The pushing core wire can reduce the resistance in the pushing process and the first release process, especially the resistance when a medical implant is in a bent state through a bent path, and solves the problem of retreating and recycling of the medical implant.

Description

Technical field [0001] The present invention relates to the field of medical devices, and more particularly to a push core wire and a medical device for medical implants. Background technique [0002] Animalioma is a severe arterial vascular lesion, and its damage to the human body is mainly reflected in two aspects. First, aneurysm increases the neurodular and arteriovenous tissue surrounding, causing the body uncomfortable or partial function loss, its secondary, arterial tumor wall aging or external reasons lead to rupture of the aneurysm, while it will endanger life, especially Brain stroke caused by brain aneurysm, has a relatively high fatal disability rate. In recent years, with the increase in people's living standards and the deterioration of the environment, the morbidity rate increases year by year. [0003] In the aneurysm, the most difficult treatment of intracranial aneurysm. At present, a recognized method of low-risk intracranial aneurysm is a minimally invasive i...
