Abstract

The present invention discloses a cardiovascular dilator and belongs to the technical field of medical devices. The cardiovascular dilator comprises an injector, a first dilating body and a second dilating body, the second dilating body is provided with multiple layers of additional dilating bodies, and the multiple layers of the additional dilating bodies are arranged at intervals in an axis direction of the second dilating body; air bags are arranged in the additional expansion bodies; and each layer of the additional dilating body is formed by evenly distributing a plurality of elastic arc-shaped protrusions, the arc-shaped protrusions of every two adjacent layers of the additional dilating bodies are distributed in a staggered mode, and a liquid outlet is formed in a lower end of the second dilating body. The second dilating body of the cardiovascular dilator conducts primary dilating, the additional dilating bodies in the second dilating body enable blood vessels to be slowly dilated, and damages to blood vessels can be effectively prevented; and channels are formed between the additional dilating bodies, so that blockage of the blood vessels is effectively prevented, normal blood circulation can still be carried out while the blood vessels are dilated, extruded and broken neoplasms in the blood vessels are brought out, operations of medical staff are easier, and view fields and operation spaces are wider.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cardiovascular dilator. Background technique [0002] The heart is a hollow muscular organ located in the middle of the thoracic cavity. It is divided into two left and right chambers by a partition. Each chamber is divided into two parts: the upper atrium and the lower ventricle. The atrium collects blood from the heart, and the ventricle ejects The blood flows out of the heart, and there are valves at the inlet and outlet of the ventricle to ensure the one-way flow of blood. The cardiovascular system is composed of the heart and blood vessels, and the blood vessels include arteries, veins and capillaries. A stent or balloon is installed in the patient's cardiovascular system, but because the cardiovascular pipeline is relatively thin, it is difficult to manually install the stent or balloon. Moreover, the balloon completely blocks blood circulation during expansion, ...
