Abstract
The utility model discloses a Y shaped stent graft for the large artery trunks, used for micro-traumatic interventional therapy for the abdominal aneurvsms. The utility model is composed of a metal graft and a Y-shaped tube stent stitched together, wherein the metal graft comprises a plurality of columnar single coils. Made of alloy wire, the columnar single coils are composed of a plurality of waves. The columnar single coils comprise three kinds of columnar single coils. After the first kind of class columnar single coils are expanded, the peaks and the wave bottoms are arranged on two lines. Compared with the first kind, the second kind of columnar single coils have smaller but more waves. After the third kind of columnar single coils are expanded, all the wave bottoms are on the same line, and outwardly from the middle peak, the peaks gradually ascend in sequence. Wherein the first kind of columnar single coils are arranged in the middle part of a main body of the stent graft, the second kind of columnar single coils are arranged in the start-position of a stent segment of the main body of the stent graft, and the third kind of columnar single coils are arranged on two branches of the stent graft. The Y shaped stent graft has the main features of integrative structure, the designing of inner-leakage-proof at the near end, better bending and compliance of the branches and broader application.
Description
Technical field
This utility model relates to a kind of Wicresoft for the treatment abdominal aortic aneurysm and hinders the interventional medical device product, relates in particular to a kind of large artery trunks overlay film frame.
Background technology
Aneurysm is very dangerous clinically a kind of angiopathy, the old people of mostly occurring in one's mid-50s, but begin in recent years gradually in, adolescence's mass-sending exhibition.Show according to the ASSOCIATE STATISTICS data: if the untimely treatment measure of taking of aneurysm patient, mortality rate in 24 hours reaches about 15%, one week reached about 30% with interior mortality rate, and the mortality rate in month reaches about 75%, and the survival rate in 5 years only is 17%.Therefore, once finding the aneurysm patient, should carry out corresponding treatment to it as early as possible.
At present, utilizing the Wicresoft of inner cavity insulation principle to hinder interventional therapeutic technique is utilized widely, it is with the thinner induction system of a cover caliber, the large artery trunks overlay film frame of confined state is sent to the position of lesion vessels, after accurately locating, with its release and covering lesion vessels, isolated tumor chamber also forms new channel of blood flow; Aneurysm is after the forfeiture blood supply, and tumor intracavity remained blood forms thrombosis gradually and flesh changes into vascular tissue, and the tumor wall of expansion state shrinks because of being subjected to negative pressure, returns near original form gradually, thereby reaches the aneurysmal purpose of treatment.
When aneurysm is positioned near the intersection of ventral aorta and iliac artery, should use the profile Y type large artery trunks overlay film frame similar to shape of blood vessel, wherein: the main part of Y type large artery trunks overlay film frame is positioned at ventral aorta, two branches lay respectively in the iliac artery, finish effectively isolated to the tumor chamber respectively, thereby reach treatment abdominal aortic aneurysm.
Because patient's lesion vessels form varies with each individual, partly there is comparatively more serious bending in patient's iliac artery greatly, and the most of Y type large artery trunks overlay film frames that existed in the market are difficult to be useful in the similar lesion vessels.Existing large artery trunks overlay film frame mainly shows at the major defect under this environment: after the large artery trunks overlay film frame discharges, and the mount proximal end internal hemorrhage due to trauma; The large artery trunks overlay film frame branch that is positioned at iliac artery easily gives a discount, and causes that internal diameter is narrow, internal hemorrhage due to trauma, support force weaken, induction system is difficult to withdraw from even support slippage or displacement etc. take place.
Summary of the invention
This utility model technical issues that need to address are a kind of Y type large artery trunks overlay film frames of design, with after overcoming large artery trunks overlay film frame that prior art exists and discharging, and the mount proximal end internal hemorrhage due to trauma; The large artery trunks overlay film frame branch that is positioned at iliac artery easily gives a discount, cause that internal diameter is narrow, internal hemorrhage due to trauma, support force weaken, induction system is difficult to withdraw from, defectives such as support slippage or displacement take place, for a kind of integral type, the anti-internal hemorrhage due to trauma design of near-end, the crooked compliance of branch is better, the indication scope is bigger is used for the Y type large artery trunks overlay film frame that interventional therapy is hindered by abdominal aortic aneurysm Wicresoft.
The technical solution of the utility model:
A kind of Y type support, constitute by a main part and two components, main part and component comprise the support of the column individual pen formation that contains a plurality of waveforms that a plurality of alloy silks are made and the tubulose overlay film of Y shape, support and overlay film are stitched together by medical surgical sewing thread, become a complete Y type overlay film frame.
Said column individual pen comprises first kind column individual pen, the second class column individual pen and the 3rd class column individual pen;
Behind the said first kind column individual pen and the second class column spread of single circle blade, all crests of waveform are all on same straight line, all troughs are also all on same straight line, and the difference of the first kind column individual pen and the second class column individual pen is: the waveform of the second class column individual pen is littler, wave number is more;
Behind said the 3rd class column spread of single circle blade, all on same straight line, all crests are outside from intermediary crest for all troughs, raise gradually successively;
After each personal connector of two ends of the said first kind column individual pen and the second class column individual pen is connected, form a cylinder respectively;
The two ends of said the 3rd class column individual pen form an oblique circular cylinder after connecting with connector;
All column individual pens become an integral body with piped overlay film by suture, promptly constitute Y type large artery trunks overlay film frame;
Column individual pen and order that the main part of said Y type support is used are: first is first kind column individual pen, and second is the second class column individual pen, and all the other are first kind column individual pen;
The column individual pen that the component of said Y type support uses is the 3rd class column individual pen;
The utility model has the advantages that fairly obvious: the second class column individual pen that is positioned at the overlay film near-end is except that providing enough support force, because waveform is little, the ripple interbody spacer is few, the blood vessel that can adapt to non-regular sections shape, and effectively increase the adherent effect of large artery trunks overlay film frame near-end, therefore can reduce the probability of near-end internal hemorrhage due to trauma significantly; The inclined-plane of the oblique circular cylinder that all the 3rd class column individual pens in the large artery trunks overlay film frame branch form is towards all toward the outer side, bigger between the then ramose adjacent column in the gap in the outside, even bigger bending takes place in branch, overlapping between adjacent column can not appear yet, avoid making the support bending, thereby guarantee the overlay film inner wall smooth, submissive, adherent better effects if, greatly improve the ramose bending of large artery trunks overlay film frame and complied with performance, make support also be suitable for treating crooked serious vascular lesion, enlarged the indication scope of large artery trunks overlay film frame, reduce operating difficulty and risk, improved the success rate of operation and the survival rate of postoperative patient.
