Blood vessel expansion equipment

Abstract

The invention relates to the technical field of medical equipment, and discloses blood vessel expansion equipment. The blood vessel expansion equipment comprises an expansion stent, a monitor, a dataprocessor and an electromagnetic suspension driving assembly; the expansion stent has the shrinkage form and the expansion form and is used for excising thromboses and expanding the blood vessels; themonitor is used for detecting the position and the form of the expansion stent, and generating data signals according to the detected position and form; the data processor is in signal connection with the monitor and is used for generating control signals according to the data signals; the electromagnetic suspension driving assembly is in signal connection with the data processor and is used fordriving the expansion stent to move according to the control signals and driving the expansion stent to be switched into the expansion form from the shrinkage form according to the control signals. The diameter of the expansion stent in the blood vessel expansion equipment in the shrinkage form can be made smaller, the blood vessel expansion equipment can be applied to thrombosis treatment of medium and small arteries and veins, and the influence of the initial guiding-in position of the expansion stent on a patient is smaller.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a blood vessel expansion equipment. Background technique [0002] In the traditional thrombus treatment plan, the stent needs to be set on the expandable balloon of the balloon catheter to move and expand, and a series of invasive equipment such as the balloon catheter must be provided. nearby (such as Figure 1a shown) to open a wound; then, insert the balloon catheter 02 covered with the stent 01 into the wound (such as Figure 1b shown), and determine the position of the stent in the blood vessel by X-ray; finally, when the stent 01 is located at the position of the thrombus, the balloon 021 is inflated to destroy the thrombus and expand the stent to support the blood vessel (such as Figure 1c and Figure 1d shown). However, there are also some problems in the above-mentioned thrombus treatment scheme, for example, the minimum diameter of the stent is limited by ...

Problems solved by technology

However, there are also some problems in the above-mentioned thrombus treatment plan, for example, the minimum diameter of the stent is limited by the diameter of the balloon, and a larger arterial vessel must be selected as the insertion site for the invasion site
