Problems solved by technology

[0003] Anticoagulant drugs and thrombolytic drugs are often used clinically for treatment, but the therapeutic effect is very insignificant. The larger the diameter of the blood vessel blocked by the thrombus, the worse the therapeutic effect is, the recanalization rate is low, and the recanalization time is long, and some patients Not suitable for thrombolytic therapy
[0004] At present, some mechanical devices are used to remove thrombus, which provides a new and efficient treatment method for blood vessel recanalization for patients with thrombosis. Mechanical thrombectomy has a short operation time and fewer related complications, and is currently a research hotspot in the fiel

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a universal thrombus smashing and extracting device with biomimetic jellyfish contraction and expansion functions. The device comprises a spraying mechanism used for spraying a thrombolytic drug, a thrombus smashing and extracting mechanism used for guiding thrombus out and connected with the spraying mechanism, a guiding mechanism used for pushing the spraying mechanism to go into a human body lumen and a power mechanism used for driving the guiding mechanism to move. According to the universal thrombus smashing and extracting device with the biomimetic jellyfish contraction and expansion functions, the spraying mechanism can go into the human body lumen by means of the guiding mechanism,then the thrombolytic drug is sprayed by the spraying mechanism so that thrombolysis can be conducted, the thrombus is smashed and extracted by the thrombus smashing and extracting mechanism, operation is convenient, the thrombus elimination speed is high, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a universal thrombus crushing device with the contraction and expansion function of bionic jellyfish. Background technique [0002] Thrombosis is due to the existence of some incentives, secondary to the endogenous or exogenous coagulation system, the platelets and other formed components in the blood are abnormally aggregated in the circulating blood to form a blood clot, and the blood clot may occur in the inner wall of the heart or On the wall of a blood vessel, causing blockage or embolism of the blood vessel, with subsequent serious bodily injury. Thrombosis spreads throughout the entire cardiovascular system, affecting tissues and organs throughout the body, not limited to myocardial infarction, deep vein thrombosis, or cerebrovascular thrombosis. Thrombosis can occur in blood vessels anywhere in the body. The incidence of venous thrombosis is higher than that of a...
