Abstract

The invention discloses a rapid dredging device for cardiovascular and cerebrovascular embolism, and relates to the field of medical instruments. The problem that an existing dredger cannot clean thrombus completely is solved. The equipment specifically comprises a probe mechanism and a moving assembly, the probe mechanism comprises a main pipe joint and an upper blocking assembly, the outer wall of the upper blocking assembly is fixedly connected with a middle assembly, and the outer wall of the bottom of the middle assembly is fixedly connected with a lower blocking assembly. By arranging the upper blocking assembly and the lower blocking assembly, the whole upper blocking assembly is guided to penetrate through a thrombus, then the middle assembly is located in a thrombus plugging area, the outer walls of one sides of the upper blocking assembly and the lower blocking assembly are located in smooth blood, at the moment, the middle rod is pushed out through the combined action of the flow guide pipe and the first air pipe, then the first air pipe is inflated, and the first air bag expands, and the inner wall of the blood vessel is blocked. Then the second air pipe and the second air bag are inflated, so that the area where the thrombus is located is completely sealed, the thrombus flowing area is sealed, and diffusion is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a rapid dredging device for cardiovascular and cerebrovascular embolism. Background technique [0002] In the field of treatment of cardiovascular and cerebrovascular diseases, minimally invasive surgery is mainly used for embolization treatment, but the basic working principle of the existing dredge is the catheter extraction method. With clean extraction, scattered plugs are at risk of reaggregation. [0003] After retrieval, the Chinese patent application number 201710814584.X discloses a rapid dredging device for cardiovascular and cerebrovascular infarction, and a device for removing vascular plaque is arranged on the dredging device. The device for fast dredging of cardiovascular and cerebrovascular infarction according to the present invention comprises a pressure-charging and negative-pressure two-in-one conduit, wherein the pressure-charging and negative-pressure two-in-o...
