Description
Technical Field
The invention relates to a peripheral blood vessel thrombus removal support, in particular to an adjustable peripheral blood vessel thrombus removal support component.
Background
According to statistics, the number of death caused by thrombus accounts for 51 percent of the total death number in China, which is far higher than that of other diseases, about 260 million people in China die of stroke and myocardial infarction which take thromboembolism as a main expression form, and about one death happens every 12 seconds on average. The current methods for treating thrombus are mainly divided into two types: drug thrombolysis and mechanical thrombus removal.
Drug thrombolytic therapy is to reduce or eliminate the symptoms of the patient by dissolving the thrombus in the arterial or venous vessels, allowing blood to circulate again. Venous thrombolysis is a common rescue method for acute cerebral infarction, and the time window from the beginning to thrombolysis is within 4.5 hours, and the shorter the time is, the better the thrombolysis effect is. However, after the thrombolytic drug passes through the whole body, the drug concentration is greatly reduced, the treatment effect is greatly reduced, the success rate can only reach about 20%, and if the drug dosage is increased, complications are easy to generate, and the risk is very high.
Mechanical thrombus removal refers to a treatment method which can recover the smoothness of blood vessels by using a special instrument to remove thrombus blocking the blood vessels. The mechanical thrombus removal is to draw the thrombus into the near-end catheter to be taken out after the thrombus is sucked in vacuum through the near end or the thrombus is contacted with the far end, so that the blood perfusion can be quickly recovered, and the blood vessel recanalization is realized. The time window of mechanical thrombus removal is less than 8 hours, so mechanical thrombus removal can be considered when the time for dissolving the thrombus by the medicine is over. Compared with the medicine thrombus removal, the mechanical thrombus removal is simpler and quicker, the risk is reduced greatly, and the subsequent blood vessel passing rate is higher.
In 2008 1 month to 2013 6 months, 80 acute cerebral infarction patients analyzed and treated by neurologists in electric hospitals in Heilongjiang province, wherein 42 patients are treated by arteriovenous combined thrombolysis, and 38 patients are treated by mechanical thrombolysis. The treatment efficiency is judged by Barthel score, the blood vessel recanalization rate is judged by adopting a myocardial infarction thrombolysis grading standard (T IM I), and the effective rate, the blood vessel recanalization rate and the near-term and long-term prognosis effects of the 2 groups are compared. The results show that the curative effective rates of the arteriovenous combined thrombolysis treatment group and the mechanical thrombus taking group are 97.6 percent and 100 percent respectively, and the difference has no statistical significance (P is more than 0.05); the blood vessel recanalization rate is 71.4 percent and 100 percent; 45.2 percent and 15.7 percent (P is less than 0.05) respectively for the residual stenosis rate which is less than or equal to 30 percent; the acute reocclusion rate of the blood vessel is 47.6 percent and 0 percent respectively (P is less than 0.05); the disease death rates are 11.9% and 0% respectively. The results show that the curative effect of the artery and vein combined thrombolysis and the mechanical thrombolysis is similar, but the short-term and long-term prognosis of the mechanical thrombolysis group is far superior to that of the arteriovenous combined thrombolysis group. Analysis proves that the treatment effect of mechanical thrombus removal is more obvious than that of drug thrombolysis, the safety is higher, the later-stage prognosis is better, and the mechanical thrombus removal is more worthy of popularization in medical clinic.
According to the above, the chinese utility model patent 201420743450.5 discloses an adjustable intracranial vascular thrombus removal device, which comprises an adjusting guide wire, a thrombus removal device, and an external fixing sheath.
