Description

Medical fixator conveyor and fixing system

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to a medical fixer conveyer and fixing system is related to.

Background

The aortic dissection or aortic aneurysm is a very dangerous vascular disease, has great threat to the life of a patient, is mainly caused by hypertension, arteriosclerosis, injury, infection and other reasons to cause the aorta to have limited dilatation, and slowly presents the aneurysm shape under the impact of high-pressure blood flow. The aorta is expanded for a long time, the vessel wall becomes very fragile, rupture is very easy to occur, once the aneurysm ruptures, a large amount of bleeding is caused, and the name of a bomb in a human body is listed as one of 10 life diseases in European and American countries. With the increasing aging of population, the improvement of people living standard and the continuous improvement of medical standard, the incidence and detection rate of aortic dissection and aortic aneurysm have been on the rising trend year by year. At present, surgical treatment methods mainly comprise open surgery, hybrid surgery and intracavity repair treatment.

The intra-cavity repair treatment, namely aortic intra-cavity repair (EVAR), is a novel minimally invasive vascular intra-cavity operation developed in recent years, and is characterized in that a conveying system loaded with a covered stent is pushed to a diseased part through an aortic far end such as a femoral artery incision of a human body, the covered stent is unfolded to isolate a diseased artery, and a blood transport channel is reconstructed, so that the pressure of an aneurysm body is reduced, and the treatment purpose is achieved. The intracavity repair treatment belongs to complete interventional therapy, does not need to open the chest and open the abdomen, and has the advantages of small surgical wound, short surgical time, quick postoperative recovery and the like compared with open treatment and hybrid surgery. Since the 90 s of the 20 th century, the advent and development of minimally invasive, intraluminal repair therapies has gradually replaced open surgical procedures as the surgical primary choice for the treatment of aortic dissections and aortic aneurysms.

Although the advantages of the conventional aortic endoluminal repair (EVAR) are obvious, at the same time, there are at least the following disadvantages: the aortic dissection and aneurysm for interventional therapy still have deficiencies, the stent is attached to the inside of a human blood vessel through self elasticity after being released, the risk of internal leakage and stent displacement is caused under the action of high-pressure and high-speed blood flow impact, the internal leakage and/or stent displacement can cause that the tumor body cannot be reduced or continuously increases after the operation, and the interventional operation cannot achieve the expected therapeutic effect and even endangers the life of a patient.

In the case of internal leakage or stent migration, it is currently common practice to implant a stent again at the proximal end of the original stent. However, this method has many disadvantages, for example, the re-implanted stent has many unstable factors due to poor anchoring conditions, the long-term operation effect is to be evaluated, and due to the branched blood vessels at the proximal end of the stent, the re-implantation of a new stent may not have enough anchoring regions to block endoleaks by the new stent.
