Embodiment Construction

[0049] The stent delivery system proposed by the present invention and its usage method will be further described in detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0050] The core idea of ​​the present invention is to provide a stent delivery system, which makes the overall release structure more efficient through the structural design of the outer tube, the rear release assembly, the coated sleeve assembly and the handle assembly and the design of the connection structure between these components. In order to be reliable, the use method of the delivery system provided by the present invention controls the release ac...

Abstract

The invention provides a stent delivering system. The stent delivering system includes an external tube, a back releasing assembly, a covered cannula assembly, and a handle assembly; and through connection structures among the parts, the whole releasing structure is more reliable. The use method of the stent delivering system is characterized in that the handle assembly controls the external tube, the covered cannula assembly and the back releasing assembly to successively perform releasing motions, and then a gradual releasing process of covered cannula releasing-stent primary releasing-stent complete releasing can be achieved. Through the gradual releasing process and the whole structure of the stent delivering system, the stent releasing accuracy of the stent delivering system can be improved, and medical accidents can be reduced.

Description

technical field [0001] The present invention relates to a medical operation device and its usage method, in particular to a stent delivery system and its usage method. Background technique [0002] A stent graft is an implantable device consisting of a tubular surgical graft sheath and a self-expanding frame. The covered stent is placed in the blood vessel, which can block the aneurysm and rebuild the blood flow path, so that the hemodynamic pressure cannot reach the vascular lesion. [0003] When the stent graft is released in the segment of the blood vessel that needs to be repaired, it needs the cooperation of the delivery system. An excellent delivery system, from the immediate point of view, needs to have the performance of precise and easy introduction, precise and safe release, and easy and easy retraction. Because whether it is a true aneurysm, a false aneurysm or a dissection aneurysm, it is due to different degrees of damage and disease of the blood vessel, and t...
