A thrombus removal device with a hidden crushing head

Abstract

The invention relates to a thrombus removing device with a concealed crushing head. The thrombus removing device comprises a main pipe, a double-joint pipe base and a crushing head, wherein the main pipe is composed of an inner pipe and an outer pipe, the double-joint pipe base is composed of a sleeve, a medicine injection branch pipe and a suction branch pipe, and the crushing head comprises a crushing head concealment pipe, a crushing rod, a control rod, an arc-shaped baffle and crushing thorns. The thrombus removing device is provided with the thrombus crushing head capable of being concealed, during normal suction, the crushing head is contracted in a suction pipeline, which cannot affect the suction operation, the crushing head stretches out from the suction pipeline and the crushingthorns are unfolded when meeting large-size high-viscosity thrombus, by rotationally operating the crushing head, the large thrombus can be broken up so as to enter the suction pipeline successfully.The thrombus removing device can perform crushing operation and suction operation simultaneously, so that the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a thrombus removal device with a hidden crushing head. Background technique [0002] A thrombus is a small piece of blood that forms on the surface of a vessel in the cardiovascular system where the lining has been peeled off or repaired. In the variable fluid-dependent type, the thrombus is composed of insoluble fibrin, deposited platelets, accumulated white blood cells, and trapped red blood cells. Thrombosis is a multifactorial process that interacts and influences each other with a set of genetic and environmental factors. The main characteristics of common clinical thrombosis patients are familial heredity, recurrence, severity of symptoms, abnormal thrombosis site, and younger onset time. Taking out the thrombus generated in the blood vessel and recanalizing the occluded blood vessel is the key to recovering the blood vessel blocked by the thrombus, and it is a...

AI Technical Summary

Problems solved by technology

Although this technical solution solves the problem of aspiration of large-volume and highly viscous thrombus, there are still some deficiencies.

First of all, the head end of the suction tube is an oblique cut opening, although it is convenient for the puncture of the suction tube, but there is also a risk of operation error and the head end punctures the blood vessel

Secondly, the operation of dispersing the thrombus and the suction operation cannot be carried out at the same time. The operation of dispersing the thrombus cannot be performed during suction, and the operation of dispersing the thrombus cannot be performed during suction. Frequent replacement of parts is required between the two operations. Complicated operation and low suction efficiency
