Abstract
The present invention relates to a kind of endovascular stents for TIPS art, to cause portal vein and Hepatic venous flow to be severely impacted when solving the problems, such as that straight tube shape overlay film frame is applied to TIPS art, while solving the problems, such as that traditional bare bracket is easy to appear tissue and leads to stent occlusion to the intracavitary hyperplasia of stand tube.It includes straight cylindrical skeleton and tubulose overlay film;The tubulose overlay film is fixed at the middle part of the straight cylindrical skeleton, so that the both ends of the straight cylindrical skeleton form exposed anchor portion.Its both ends are capable of forming the anchor portion with open-work, and locating effect is excellent, and open-work can reduce the influence to blood flow intravascular at anchoring in application by blood flow.
Description
Technical field
The present invention relates to Medical rack technical fields, and in particular to a kind of TIPS(transjugular intrahepatic
Portosystemic shunt) the dedicated endovascular stent of operation.
Background technique
In the world, cirrhosis is the fourth-largest lethal factor after tumour, cardiovascular disease, chronic lung disease
(non-communicable diseases), in past 20 years, the death rate caused by cirrhosis and liver cancer increases about 50,000,000 every year.Study carefully its original
Because being because hepatopathy compensation is powerful, the concealment of hepatopathy onset is asymptomatic.Liver cirrhosis patient is only being developed to decompensation
Phase can just show various Decompensated stage symptoms.In cirrhosis patients in decompensation, Esophago-gastric varices will occur in patient.Once
The esophageal varices rupture haemorrhage of varicose will cause serious massive hemorrhage of gastrointestinal tract.Alimentary canal caused by Cirrhotic Portal Hypertension
Bleeding accounts for about the 70% of entire Diagnosing Gastrointestinal Bleeding.The first time bleeding death rate can reach 15-20%, if liver when patient's bleeding
Function is Child-Pugh C grades, and the death rate can reach 30%.
Referring to Fig. 1, transjugular intrahepatic portosystemic shunt (transjugular intrahepatic
Portosystemic shunt, TIPS) passing through endovascular stent 2 in liver parenchyma 11 between portal vein 13 and vena hepatica 14
Set up split channel.TIPS art can not only reduce portal venous pressure, but also it is thorough to combine esophageal varices Embolization
Treatment Cirrhotic Portal Hypertension caused by hemorrhage of digestive tract.TIPS art has become treatment Cirrhotic Portal Hypertension alimentary canal at present
One of most important treatment method of bleeding.The bracket that current TIPS art can use includes bare metal stent, overlay film frame
(Fluency, Viabahn) and Viatorr overlay film frame.
There are two types of the production methods of bare metal stent: the first, gone out by laser-induced thermal etching with mesh in tubular metal
Tubular bracket, the bare metal stent rigidity that this method is produced is high, and support force is strong, but flexibility is poor;Second, pass through metal
Silk knits out the tubular bracket with mesh, and the bare metal stent flexibility that this method is produced is good, but support force is poor.It is using
When, body tissue can be grown by mesh into bare metal stent, and the lumen in bare metal stent is caused to block.Overlay film frame
(Fluency, Viabahn) and Viatorr compound film laminating bracket are to be covered with PTFE film on the outside of bare metal stent, due to
The blocking of PTFE film, tissue will not be to bare metal stent pipe Intracavities, and unobstructed effect at a specified future date is good.
Present inventor studies discovery: 1. when establishing door body split channel in liver using bare brackets, and body tissue can be with
By stent mesh to the intracavitary hyperplasia of stand tube, postoperative restenosis incidence is higher;2. bare bracket is unable to closure gate venipuncture
The cut at point place, the risk of portal vein point of puncture generation bleeding is higher in art;3. overlay film frame and bare bracket combined application are used, it can
With comprehensive two kinds of bracket advantages, but use two pieces of brackets costly, operative process is excessively complicated;4. using
Viatorr overlay film frame can simplify partial surgical operation, but the bracket proximal part is overlay film frame, influences vena hepatica trunk
And the blood flow of inferior caval vein.
Summary of the invention
Goal of the invention of the invention is to provide a kind of dedicated endovascular stent of TIPS operation, to pass through technical strategies
Mode when solving straight tube shape overlay film frame applied to TIPS operation caused by portal vein and vena hepatica blood vessel turnoff blood
The technical issues of stream is affected.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
Design a kind of dedicated endovascular stent of TIPS operation, including straight tube shape elastic skeleton and tubulose overlay film;The tubulose covers
Film is fixed at the middle part of the straight tube shape elastic skeleton, so that the both ends of the straight tube shape elastic skeleton form exposed anchor
Determine portion, open-work is equipped in the anchor portion.
Preferably, the straight tube shape elastic skeleton is laser engraving skeleton, in the laser engraving skeleton and the tubulose
The front end boundary of overlay film is equipped with developing mark point in the anchor portion.
Preferably, the straight tube shape elastic skeleton is metal wire knitted skeleton, in the front end of the metal wire knitted skeleton
It is formed with swollen thick changeover portion, the tubulose overlay film is equipped on the swollen thick changeover portion.
Compared with prior art, the beneficial effects of the present invention are:
The overlay film part of interlude can prevent the hyperplasia of postoperative inner membrance, improve bracket long-term patency rate;Both ends bare bracket forms band
There is the anchor portion of open-work, locating effect is excellent, and open-work can penetrate blood flow, can be greatly reduced in application to portal vein and liver
The influence of the blood flow of the blood vessel turnoff of vein.
The present invention can be also used for vena iliaca externa compression syndrome in addition to it can be used for portosystemic shunt in liver (TIPS) operation
With on the bow of aorta pectoralis endovascular repair points of artery orthotopic fenestration art.
