Blood vessel stent device and use method thereof

Abstract

The invention relates to a blood vessel stent device and use methods thereof. The caliber of the front half section of the blood vessel stent device can be equal to the caliber of the rear half section of the blood vessel stent device, or the caliber of the front half section of the blood vessel stent device can be larger than or less than the caliber of the rear half section of the blood vessel stent device, so as to adapt to blood vessels of different size of a receptor. The use methods of the blood vessel stent mainly comprise two use methods, i.e. an end-to-end anastomosis method and an end-to-side anastomosis method, wherein an end-to-end part is that a guide wire is put in a receptor blood vessel which is to be used as a anastomosis blood vessel, the other section of blood vessel to be anastomosed is sheathed on the guide wire, and the blood vessel stent for anastomosis is slid into the receptor blood vessel along the guide wire. The strip label of the blood vessel stent can be directly seen from a transparent blood vessel sheath. When the strip label is between two blood vessel sections, the blood vessel sheath is dropped back to release the self-expandable blood vessel stent to complete the anastomosis. The invention has the advantages that the surgical process can be effectively simplified, the surgical time is saved, the surgery success rate is improved and the like.

Description

technical field [0001] The invention relates to the technical field of vascular stents, in particular to a vascular stent device capable of effectively simplifying the operation process, saving operation time and improving the success rate of the operation, and a method for using the same. Background technique [0002] In the field of commonly used vascular anastomosis techniques, end-to-side anastomosis (end-to-side anastomosis) and end-to-end anastomosis (end-to-end anastomosis) are the basic technical skills, and suture techniques include continuous suture (continuous suture ) and interrupted suture, but no matter what kind of anastomosis, the problem of anastomosis stricture (anastomosis stricture) cannot be avoided. The most common reasons for this phenomenon include poor surgical technique (technical error) and surgical The abnormal endothelial hyperplasia caused by secondary vascular endothelial damage, and these two causes of anastomotic stenosis cannot be completely...

Problems solved by technology

The third reason is that the implanted artificial blood vessel 150 is different from the compliance of the blood vessels at the anastomosis, causing the stenosis at the anastomosis to cause thrombus formation.
