Partial-sealing reverse-flow type blood clot resorption device

Abstract

Provided is a partial-sealing reverse-flow type blood clot resorption device. The partial-sealing reverse-flow type blood clot resorption device comprises a balloon, a balloon catheter, a blood clot removing drill bit, a blood supplementing tube and a collecting tube. The blood clot removing drill bit is of a hollow structure and is connected and communicated with the blood supplementing tube. The blood clot removing drill bit and the blood supplementing tube are sleeved with the collecting tube, and the collecting tube, the blood clot removing drill bit and the blood supplementing tube form a collecting tube cavity which is communicated with a blood clot suction outlet. The partial-sealing reverse-flow type blood clot resorption device has following beneficial effects: blood clot scraps can be sucked out of the human body through the collecting tube after blood clots are smashed; meanwhile, blood is supplemented through the blood supplementing tube for blood loss, and therefore the pressure intensity inside the blood vessel is maintained; in addition, thrombolytic drugs can be injected at the same time; and besides, the blood supplementing type blood clot remover is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a medical device, in particular to a partially blocked backflow thrombus suction device. Background technique [0002] In the cardiovascular system of a living body, the process of coagulation of blood or the formation and coagulation of certain substances in the blood to form solid masses is called thrombus formation. Different from blood clots, thrombus is a small piece of blood formed on the surface of the peeled or repaired part of the inner surface of the cardiovascular system under the state of blood flow. The thrombus may dislodge and enter the pulmonary artery along the direction of blood flow, causing fatal pulmonary embolism with a high fatality rate. [0003] Considering the severity and prevalence of diseases related to thromboembolism (such as cardiac embolism, cerebral embolism, organ embolism, peripheral thrombosis, etc.), various techniques for dissolving or removing thrombus have been developed, and the common...

AI Technical Summary

Problems solved by technology

However, there will be small blood clots generated during the grasping process, which remain in the blood vessel and cannot be removed

[0010] The above-mentioned prior art still has the following deficiencies: the intima of the blood vessel is damaged during the thrombus scraping process, and secondary thrombus is easily formed; the broken small thrombus pieces produced during the scraping and thrombus part remain in the blood and enter the bypass arteries and organs, which may cause Embolism or failure of related organs
