Description

Technical Field

[0001] The present invention relates to the technical field of vascular stents, and in particular to an implantation device for vascular stents. Background Art

[0002] A vascular stent is a stent that is inserted into the diseased segment on the basis of luminal balloon dilatation to support the narrowed and occluded segment of the blood vessel, reduce the elastic retraction and reshaping of the blood vessel, and maintain smooth blood flow in the lumen. Vascular stents can be divided into simple support stents and therapeutic stents according to their functions. Therapeutic stents include stents or radioactive stents that are coated with drugs on the surface of the stent or use the outer film of the stent to carry therapeutic substances. Vascular stents can be divided into self-expanding and balloon-expandable types according to the way they are deployed in the blood vessel. The former, such as Z-shaped stents and mesh stents, can expand themselves in the blood vessel, while the latter are inelastic and rely on balloon expansion to a certain diameter value to adhere to the blood vessel.

Before the operation, the single-layer densely woven vascular stent is radially compressed and attached to the end of the push rod with the metal wedge, and the push rod is rotated in the direction of the metal wedge, so that the metal wedge is wedged into the mesh of the densely woven stent to firmly grasp the vascular stent. When releasing, the microcatheter is first completely withdrawn from the surface of the vascular stent, and then the push rod is rotated in the opposite direction of the metal direction to withdraw the metal sheet wedged into the mesh of the vascular stent, so that the vascular stent loses its grip and achieves the purpose of final release.
